The positioning device2has a locked state and an unlocked state. In the locked state, the positioning device2extends into the receiving groove a and is fitted with the window300to position the window300. In the unlocked state, the positioning device2is separated from the window300.

Thus, the user may control the positioning device2to be in the locked state so as to position the window300in the receiving groove a, without any other auxiliary parts such as a screw, which simplifies the process of positioning the window300after the user mounts the window air conditioner100. The operation to position the window300by user is simple. Further, it is effectively avoided that the window300is destroyed by dismounting and mounting the window air conditioner100, and also it helps to reduce the cost of mounting the window air conditioner100.

The user may also control the positioning device2to be in the unlocked state so as to unlock the window300positioned in the receiving groove a, such that the window300is separated from the positioning device2, and hence it is convenient to open the mounting opening201. Thus, the user may enjoy fresh air or dismount the window air conditioner100, and hence the way to detach the window air conditioner100from the window300is simple and easy to handle.

As mentioned above, after mounting the window air conditioner100according to embodiments of the present disclosure, the user may control the positioning device2to be in the locked state or the unlocked state so as to position or unlock the window300in the receiving groove a according to the actual needs. Thus, the window300can be effectively fixed, and it is convenient for the user to mount and dismount the window air conditioner100. The mounting and dismounting processes of the window air conditioner100are effectively simplified, and the comfort for the user is improved. Moreover, the window300is effectively avoided from being destroyed by dismounting and mounting the window air conditioner100.

In the window air conditioner100according to embodiments of the present disclosure, with the positioning device2positioning or being separated from the window300, the window300can be effectively fixed, and the mounting and dismounting processes of the window air conditioner100are simplified, which facilitates the user to mount and dismount the window air conditioner100and improves the user's comfort.

As illustrated inFIGS. 1-5, according to some embodiments of the present disclosure, the positioning device2is arranged at a side wall of the indoor part12close to the outdoor part11. Thus, the reliability of positioning the window300by the positioning device2can be ensured to a certain degree, and also an occupied space of the window air conditioner100can be reduced, thus ensuring the light transmission area of the window300.

In some embodiments of the present disclosure, the positioning device2includes a positioning member211and a first elastic member212.

One end of the positioning member211is arranged at the indoor part12, and the other end of the positioning member211extends towards the receiving groove a with respect to the indoor part12. The other end of the positioning member211is movable with respect to the indoor part12. One end of the first elastic member212is fitted with the positioning member211to normally push the other end of the positioning member211to move into the receiving groove a to the locked state. Hence, the structure of the positioning device2is simple.

In the process of placing the window300in the receiving groove a, when the window300passes by the positioning member211, the window300squeezes the positioning member211so that the positioning member211overcomes a push force of the first elastic member212and moves to the indoor part12, so as to ensure that the window300extends into the receiving groove a. When the window300is placed, the positioning member211abuts against the window300under the push force of the first elastic member212, so as to be in the locked state, thus positioning the window300, so that the window300can be stably arranged in the receiving groove a.

When the user needs to move at least a part of the window300out of the receiving groove a, he/she only needs to press the positioning member211manually so that the positioning member211overcomes the push force of the first elastic member212and moves to the indoor part12, so as to be in the unlocked state. Then, the positioning device2is separated from the window300.

Furthermore, as illustrated inFIG. 2andFIG. 5, the positioning device2also includes a mounting shaft213, an abutting protrusion214and a connecting plate215. The mounting shaft213is arranged at the indoor part12. The abutting protrusion214is arranged at an end of the mounting shaft213facing to the receiving groove a. The connecting plate215is connected with the positioning member211, and sleeved over the mounting shaft213. The connecting plate215is movable with respect to the mounting shaft213. The first elastic member212is sleeved over the mounting shaft213and abuts against the connecting plate215.

Thus, when the positioning member211is not subject to an external force, the connecting plate215moves along the mounting shaft213to the abutting protrusion214driven by the first elastic member212. Since the connecting plate215is connected with the positioning member211, the positioning plate211moves synchronously with the connecting plate215to the locked state. When the positioning device2is in the unlocked state, the positioning member211moves to the indoor part12under action of the external force, and thus the connecting plate215compresses the first elastic member212. Therefore, the reliability of the first elastic member212normally drives the other end of the positioning member211to move into the receiving groove a to the locked state is ensured, and the structure of the positioning device2for positioning the window300is simple and reliable.

Specifically, the first elastic member212is a spring, which helps to reduce the manufacturing cost of the window air conditioner100and ensures the reliability of the first elastic member212pushing the positioning member211to move to the locked state. The first elastic member212may also be formed by other materials as long as the reliability of the positioning device2is ensured.

Further, as illustrated inFIG. 5, the positioning device2also includes a connector216, and the connector216passes through the side wall of the indoor part12and is fitted with a connecting hole213ain the mounting shaft213so as to fix the mounting shaft213to the indoor part12. Thus, the reliability of the positioning device2being arranged at the indoor part12can be ensured, and also it is convenient for the user to mount and dismount the positioning device2.

Specifically, the connector216is a screw and the connecting hole213ais a threaded hole. Therefore, the cost of the connector216is low, and also the reliability of the fit of the connector216and the connecting hole213acan be ensured, which facilitates mounting and dismounting of the positioning device2.

Optionally, the connecting plate215is integral with the positioning member211. Thus, the production efficiency of the window air conditioner100can be enhanced, and the structural strength and reliability of the positioning device2can be improved.

Specifically, as illustrated inFIG. 5, the one end of the positioning member211passes through the side wall of the indoor part12and extends into the indoor part12. The two ends of the positioning member211are rotatable with respect to the indoor part12. Hence, the reliability of the other end of the positioning member211located in the receiving groove a moving with respect to the indoor part12can be ensured.

Furthermore, the first elastic member212is arranged in the indoor part12and fitted with the one end of the positioning member211in the indoor part12for normally driving the other end of the positioning member211in the receiving groove a to rotate to the locked state. Thus, the reliability of the positioning device2can be ensured. Also, the structure of the positioning device2is simple and the cost is low.

Optionally, the positioning member211is a sheet-metal part. Thus, the strength of positioning member211can be ensured, and thus the reliability of positioning device2can be ensured.

Optionally, the positioning member211is integral with the casing1. Thus, the production efficiency of the window air conditioner100can be improved.

As illustrated inFIGS. 6-11, according to some other embodiments of the present disclosure, the positioning device2includes a rotating member221and a rotating drive member222.

One end of the rotating member221is rotatably arranged at the indoor part12, and the rotating member221is provided with a sliding slot221aextending along its length direction. The rotating drive member222is rotatably arranged at the indoor part12through a pivot shaft222a. The rotating drive member222is provided with a drive shaft222bwhich extends into the sliding slot221aand is movably fitted with the sliding slot221a. The drive shaft222bis spaced apart from the pivot shaft222a. The rotating drive member222rotates to drive the other end of the rotating member221to rotate between a locked state and an unlocked state through the drive shaft222b. Thus, in the window air conditioner100according to embodiments of the present disclosure, the positioning device2switches between the locked state and the unlocked state through the rotating drive member222driving the rotating member221to rotate.

Thus, in the process of placing the window300in the receiving groove a, the rotating drive member222may be controlled to rotate so as to drive the other end of the rotating member221to rotate to the unlocked state through the drive shaft222bsliding in the sliding slot221a. Thus, a gap between the positioning device2and the window300is ensured such that the window300can be placed in the receiving groove a. After the window300is placed in position, the rotating drive member222may be controlled to rotate so as to drive the other end of the rotating member221to rotate to the locked state through the drive shaft222bsliding in the sliding slot221a, and then the other end of the rotating member221is fitted with the window300to position the window300.

When the user needs to move at least a part of the window300out of the receiving groove a, he/she only needs to control the rotating drive member222to rotate so as to drive the other end of the rotating member221to rotate to the unlocked state through the drive shaft222bsliding in the sliding slot221a. Then, the positioning device2is separated from the window300and thus it is ensured that the at least part of the window300can be moved out of the receiving groove a.

In addition, as illustrated inFIGS. 7 and 9, the rotating drive member222includes a cam222c, and the cam222cis rotatably arranged at the indoor part12through the pivot shaft222a, and the drive shaft222bis arranged at the cam222c. Thus, the cam222crotates to drive the drive shaft222bto slide in the sliding slot221a, so as to drive the other end of the rotating member221to rotate, so that the positioning device2can switch between the locked state and the unlocked state. The arrangement of the cam222ceffectively ensures the reliability of the positioning device2.

Furthermore, as illustrated inFIGS. 7 and 9, the rotating drive member222also includes a rotating knob222d, and the rotating knob222dis arranged at the cam222cto drive the cam222cto rotate. That is, the user may control the cam222cto rotate by rotating the rotating knob222d, so as to drive the drive shaft222bto drive the other end of the rotating member221to rotate, so that the positioning device2can switch between the locked state and the unlocked state. Hence, the reliability of the positioning device2is further ensured, the user's operation is facilitated and the user's comfort is improved.

Specifically, at least a part of the rotating knob222dis arranged outside the indoor part12. Thus, it is convenient for the user to rotate the knob222d, thereby improving the comfort of the user operating the positioning device2.

Furthermore, the rotating knob222dis arranged at a left side and/or a right side of the indoor part12. Thus, it is convenient for the user to operate the rotating knob222dindoors, thereby improving user's comfort.

Optionally, the sliding slot221aruns through the rotating member221in a thickness direction of the rotating member221. Thus, the reliability of the drive shaft222bsliding in the sliding slot221acan be effectively ensured, thereby ensuring the reliability of the positioning device2.

Specifically, the other end of the rotating member221is formed to have a cone shape. Thus, the reliability of the fit between the other end of the rotating member221and the window300can be effectively ensured. That is, the reliability of the positioning device2positioning the window300is ensured. The other end of the rotating member221is not limited to having a cone shape, but may also be formed to have other shapes, as long as the reliability of the positioning device2positioning the window300is ensured.

Specifically, as illustrated inFIG. 9, the positioning device2includes a rotating shaft223, and the rotating shaft223is fixed to an inner wall on the left side and/or the right side of the indoor part12, and the one end of the rotating member221is rotatably arranged at the rotating shaft223. Thus, the rotating member221may be driven by the drive shaft222bto rotate with respect to the rotating shaft223, so that the positioning device2may switch between the locked state and the unlocked state.

As illustrated inFIGS. 12-17, according to some other embodiments of the present disclosure, the positioning device2includes a cover231, a second magnetic member233and a second elastic member234.

One end of the cover231is rotatably arranged at the indoor part12, and the cover231is provided with a first magnetic member232. The second magnetic member233is arranged at the indoor part12. When the second magnetic member233is in a power-off state, it is nonmagnetic. When the second magnetic member233is in a power-on state, the second magnetic member233and the first magnetic member232attract each other to control the cover231to rotate to the unlocked state. An end of the second elastic member234abuts against the cover231, so as to normally push the cover231to rotate to the locked state.

Thus, in embodiments of the present disclosure, without an external force, the cover231normally rotates to the locked state driven by the second elastic member234. When the second magnetic member233is powered on, the second magnetic member233and the first magnetic member232of the cover231attract each other, and then the cover231overcomes a push force of the second elastic member234and rotates to the unlocked state so as to be separated from the window300. That is, in the window air conditioner100according to embodiments of the present disclosure, the positioning device2may be controlled to be in the locked state or the unlocked state by controlling the power on and the power off of the second magnetic member233.

Thus, in the process of placing the window300in the receiving groove a, the second magnetic member233may be controlled to be powered on, so that the second magnetic member233is attracted to the first magnetic member232of the cover231. Thus, the cover231overcomes the push force of the second elastic member234and rotates to the unlocked state, such that it is ensured that there is a gap between the positioning device2and the window300, and hence the window300can be placed in the receiving groove a. After the window300is placed in position, the second magnetic member233may be controlled to be powered off, and then the cover231rotates to the locked state under the push of the second elastic member234, so that the cover231may be fitted with the window300effectively to position the window300.

When the user needs to move at least a part of the window300out of the receiving groove a, he/she only needs to control the second magnetic member233to be powered on so that the second magnetic member233attracts the first magnetic member232of the cover231, and then the cover231overcomes the push force of the second elastic member234and rotates to the unlocked state. Thus, the positioning device2is separated from the window300, and it is ensured that the at least part of the window300can be moved out the receiving groove a.

It should be understood that, in the case of power outage, the user may manually press the cover231which is in the locked state so that the cover231overcomes the push force of the second elastic member234and rotates to the unlocked state. Thus, the positioning device2is separated from the window300, and it is ensured that the at least part of the window300can be moved out of the receiving groove a. Therefore, the usage flexibility of the positioning device2is improved.

Furthermore, as illustrated inFIGS. 12 and 15-17, the positioning device2also includes a battery box235and a switch236. The battery box235is arranged in the indoor part12and electrically connected with the second magnetic member233. The switch236is arranged at an outer side wall of the indoor part12. The switch236is electrically connected with the battery box235to control the second magnetic member233to be powered on or off. Thus, the second magnetic member233is powered by the battery box235. The power on and the power off of the second magnetic member233are controlled by the switch236. The user may directly control the power on and the power off of the second magnetic member233through the switch236indoors, so that the way of controlling the positioning device2to be in the locked state or the unlocked state is simple for the user, thus effectively improving the user's comfort.

In addition, as illustrated inFIGS. 16 and 17, the positioning device2also includes a position limiting structure237and a support bar238. The position limiting structure237is arranged at the indoor part12, and the support bar238is fixed to the cover231. The support bar238passes through the position limiting structure237, and is movable with respect to the position limiting structure237. The second elastic member234is sleeved over the support bar238, and the two ends of the second elastic member234abut against the support bar238and the position limiting structure237, respectively. Thus, the support bar238is arranged at an inner side of the cover231. The arrangement of the support bar238and the position limiting structure237ensures the push force of the second elastic member234to the cover231, and also helps to restrict a rotation path of the cover231, so as to avoid the influence on the reliability of the positioning device2caused by the cover231deviated from the rotation path due to a long-term rotation to a certain degree, thus improving the reliability of the positioning device2and the reliability of the window air conditioner100.

Specifically, as illustrated inFIG. 17, the position limiting structure237is provided with a position limiting through hole237a, and the support bar238passes through the position limiting through hole237aso as to move with respect to the position limiting structure237. Thus, the reliability of the overall structure of the positioning device2is improved, the rotation path of the cover231is further restricted, and the reliability of the window air conditioner100is improved.

Furthermore, as illustrated inFIG. 17, the position limiting structure237is provided with a mounting groove237bwhose opening faces to the cover231, and the second magnetic member233is arranged in the mounting groove237b. When the cover231is in the unlocked state, the first magnetic member232is attached to the second magnetic member233. Thus, an attracting force between the second magnetic member233and the first magnetic member232is ensured when the second magnetic member233is powered on, and also it is convenient to mount and position the second magnetic member233, such that the reliability of the structure of the positioning device2can be improved to a certain degree, and the structure of the positioning device2is miniaturized.

Specifically, the indoor part12is provided with a through hole. In the unlocked state, the cover231is fitted in the through hole to close the through hole. In the locked state, at least a part of the cover231rotates to the outside of the through hole. That is, the cover231is formed by a part of the side wall of the indoor part12, so as to reduce the manufacturing cost of the window air conditioner100. Moreover, the cover231is arranged at the side wall of the indoor part12close to the outdoor part11in this case. Thus, the reliability of the positioning device2positioning the window300can be further ensured, and the light transmission effect of the window300can be ensured.

Optionally, a plurality of the positioning devices2are provided and spaced apart from one another along the width direction of the mounting opening201. Thus, the window air conditioner100can effectively position the window300and the reliability of the window300being placed in the receiving groove a is ensured. Even if one of the plurality of the positioning devices2fails, the user may position the window300through the other positioning devices2of the window air conditioner100, thus improving the reliability of the window air conditioner100and facilitating to prolong a service life of the window air conditioner100.

According to some embodiments of the present disclosure, the casing1may include a chassis13, and the chassis13may be arranged at a bottom of the cabinet10and disposed on the wall200. The window air conditioner100also includes a sealing device30, and a connecting end34of the sealing device30is connected with the casing1.

As illustrated inFIGS. 18, 22, 25 and 30, the sealing device30includes a fixing member31and a sliding member32.

As illustrated inFIG. 30, the fixing member31may be connected with the casing1of the window air conditioner100, and the sliding member32may be slidably fitted with the fixing member31. The sliding member32may have a first position and a second position. In the first position, the sliding member32may overlap the fixing member31. In the second position, the sliding member32may slide out of the fixing member31and have contact with the mounting opening201. The fixing member31and the sliding member32may have contact with the window300respectively, so as to seal a gap between the window300and the mounting opening201.

Specifically, when the window air conditioner100is mounted, the window air conditioner100may be placed in the mounting opening201. The window300may move up and down with respect to the wall200. When the window300moves down, it may extend into the receiving groove a of the cabinet10. Thus, the indoor part12of the window air conditioner100may be separated from the outdoor part11of the window air conditioner100. It should be understood that, when the window air conditioner100is mounted, there is a gap between the window300and the mounting opening201. If the gap is not sealed, the window air conditioner100is prone to have a cold air leakage, thus affecting the cooling and heating efficiency of the window air conditioner100. The sealing device30may be used to seal the gap between the window300and the mounting opening201, so as to prevent the window air conditioner100from having the cold air leakage, thus improving the sealing effect of the indoor space, and further improving the cooling and heating effect of the window air conditioner100.

An end of the fixing member31may be fixedly connected with the casing1of the window air conditioner100, and the sliding member32may slide with respect to the fixing member31, so as to adjust a length of the sealing device30. When the sealing device30is in transit, the sliding member32may be in the first position. In this case, the sliding member32and the fixing member31are overlapped, so as to reduce the occupied volume of the sealing device30, thus facilitating the carriage of the sealing device30. When the sealing device30is in operation, the sliding member32may be moved to the second position. In this case, the sliding member32and the fixing member31may be closely fitted with the inner wall of the mounting opening201, respectively, so as to seal the gap between the mounting opening201and the window300.

Optionally, when the sliding member32is in the second position, a sliding distance of the sliding member32with respect to the fixing member31may be selected and set according to an actual need. For example, when a distance between an outer peripheral wall of the casing1of the window air conditioner100and the inner wall of the mounting opening201is large, an extension distance of the sliding member32may be prolonged. When the distance between the outer peripheral wall of the casing1of the window air conditioner100and the inner wall of the mounting opening201is small, the extension distance of the sliding member32may be shortened. Thus, through the above arrangements, a usage flexibility may be improved for the user, and the sealing device30may be applied to different types of mounting openings201, so as to improve the sealing effect of the sealing device30.

Optionally, as illustrated inFIG. 32, the inner wall of the mounting opening201may be provided with a window frame301, and the chassis13may be arranged at the window frame301, so as to improve the sealing effect between the mounting opening201and the window air conditioner100. When the window air conditioner100is mounted, the window300may move downwards with respect to the wall200and extend into the receiving groove a, and the sealing device30may be closely fitted with an inner peripheral wall of the window frame301, so as to improve the sealing effect between the window300and the mounting opening201.

Optionally, the sealing device30may be a non-metallic part, and the non-metallic part has advantages of a light weight as well as easy mounting and dismounting. For example, the sealing device30may be made of non-metallic materials such as plastics, rubber and silica gel. Of course, the sealing device30may also be a metal part, and the metal part has advantages of a firm structure and a long service life. For example, the sealing device30may be a sheet-metal part.

Optionally, the sealing device30may have a detachable connection with the casing1. The sealing device30may be configured to have different models. The different models of the sealing devices30may have different lengths and heights. Thus, an appropriate sealing device30may be selected according to a distance between the casing1and the mounting opening201and a height difference between a bottom wall of the receiving groove a and the inner wall of the mounting opening201, so as to improve the applicability of the sealing device30, thus resulting in a close fit structure between the sealing device30and the mounting opening201and hence providing a good sealing effect.

As illustrated inFIGS. 18-19, according to some embodiments of the present disclosure, the sealing device30may also include a locking member33, the fixing member31is provided with a plurality of first positioning holes311spaced apart from one another and the sliding member32is provided with a plurality of second positioning holes321directly opposite to the first positioning holes311. In the second position, the locking member33may pass through the first positioning hole311to be fitted with the second positioning hole321so as to position the sliding member32, thus improving the sealing effect of the sealing device30.

Specifically, the locking member33may position the sliding member32. When the sliding member32is in the second position, the locking member33may prevent the sliding member32from moving with respect to the mounting opening201, so as to ensure that the sliding member32is closely fitted with the inner wall of the mounting opening201. In the specific example illustrated inFIG. 19, the fixing member31is provided with the plurality of first positioning holes311running through the fixing member31along an up and down direction. The sliding member32is provided with the plurality of second positioning holes311running through the sliding member32along the up and down direction. A distance between two adjacent first positioning holes311is the same with that between two adjacent second positioning holes321. Thus, the first positioning hole311may be easily aligned with the second positioning hole321through the above configurations, such that it is ensured that the locking member33can be smoothly inserted into the first positioning hole311and the second positioning hole321. Optionally, the locking member33may be a positioning pin, and the positioning pin is easy to process and low in cost, thus reducing a usage cost of the sealing device30.

As illustrated inFIGS. 25-26, according to some embodiments of the present disclosure, one of the fixing member31and the sliding member32may be provided with a positioning part312, and the other one of the fixing member31and the sliding member32may be provided with a sliding guide rail322fitted with the positioning part312. The positioning part312may have a deformed state and a positioned state, and the sliding guide rail322may have a plurality of positioning grooves3221spaced apart from one another along a length direction of the sliding guide rail322. In the positioned state, at least a part of the positioning part312may extend into the positioning groove3221to only restrict the degree of freedom of movement of the sliding member32in a direction approaching the fixing member31. In the deformed state, the positioning part312may be separated from the positioning groove3221. Thus, the fit of the fixing member31and the sliding member32may be firm, and the sealing effect of the sealing device30may also be improved.

Specifically, the fixing member31may be provided with the positioning part312, and the sliding member32may be provided with the sliding guide rail322. Or, the fixing member31is provided with the sliding guide rail322, and the sliding member32is provided with the positioning part312. When the positioning part312is in the positioned state, the positioning part312always extends into the positioning groove3221of the sliding guide rail322, and the sliding member32may slide freely in a direction running away from the fixing member31. When the sliding member32slides in the direction approaching the fixing member31, the positioning part312may abut against an inner peripheral wall of the positioning groove3221so as to prevent the sliding member32in the second position from sliding in the direction approaching the fixing member31, so that it is ensured that the sliding member32is closely fitted with the inner wall of the mounting opening201. When the distance between the window air conditioner100and the mounting opening201shortens, the positioning part312may be in the deformed state, and the positioning part312may be separated from the positioning groove3221. Thus, the positioning part312may slide freely.

As illustrated inFIG. 27, in some embodiments of the present disclosure, the positioning part312may have a first inclined surface3122aand a second inclined surface3122b. An included angle α between the first inclined surface3122aand a reference plane is larger than 90 degrees, and an included angle β between the second inclined surface3122band the reference plane is 90 degrees. The reference plane may be a horizontal plane parallel to an extension direction of the sliding guide rail322. Each positioning groove3221may have a third inclined surface3221aand a fourth inclined surface3221b, the third inclined surface3221amay be arranged parallel to the first inclined surface3122a, and the fourth inclined surface3221bmay be arranged parallel to the second inclined surface3122b. When the sliding member32moves in the direction running away from the fixing member31, the first inclined surface3122aand the third inclined surface3221aare slidably fitted with each other. When the sliding member32moves in the direction approaching the fixing member31, the second inclined surface3122babuts against the fourth inclined surface3221bto restrict the movement of the sliding member32. Thus, by the above configuration, the fit between the positioning part312and the sliding guide rail322is simple and the positioning effect is great.

For example, as illustrated inFIG. 27, the positioning part312includes a connecting arm3121and an assembling protrusion3122, the connecting arm3121may be connected with the sliding member32or the fixing member31, and the assembling protrusion3122is connected to the connecting arm3121and extends into the positioning groove3221. The assembling protrusion3122has the first inclined surface3122aand the second inclined surface3122b. The included angle α between the first inclined surface3122aand the horizontal plane is 120 degrees, and the included angle β between the second inclined surface3122band the horizontal plane is 90 degrees. The positioning groove3221has the third inclined surface3221aand the fourth inclined surface3221barranged opposite to each other in a left and right direction. The third inclined surface3221ais arranged parallel to the first inclined surface3122a, and the fourth inclined surface3221bis arranged parallel to the second inclined surface3122b. When the positioning part312is in the positioned state, the assembling protrusion3122always extends into the positioning groove3221. When the positioning part312is in the deformed state, the connecting arm3121is elastically deformed, such that the assembling protrusion3122may be driven to be separated from the positioning groove3221.

As illustrated inFIG. 26, in some embodiments of the present disclosure, one of the fixing member31or the sliding member32is provided with an assembling groove313, and the positioning part312may be arranged in the assembling groove313. The positioning part312has elasticity such that the overall structure of the sealing device30is compact. For example, the positioning part312may be arranged at the fixing member31, and the fixing member31is provided with the assembling groove313for accommodating the positioning part312, such that the overall structure of the positioning part312is compact. Since the positioning part312is elastic, the positioning part312may be elastically deformed, thus facilitating the separation of the positioning part312and the positioning groove3221.

As illustrated inFIGS. 22-24, according to some embodiments of the present disclosure, the fixing member31may be sleeved over the sliding member32. In the first position, the sliding member32may be received in the fixing member31, such that the fit of the fixing member31and the sliding member32is simple. Optionally, both the fixing member31and the sliding member32may be configured as hollow members, and at least one of the fixing member31and the sliding member32may be provided with a heat insulation layer. That is, the heat insulation layer may be provided only on an inner wall of the fixing member31, or only on an inner wall of the sliding member32, or both on the inner wall of the fixing member31and on the inner wall of the sliding member32at the same time, so as to improve the heat insulation effect of the sealing device30. Furthermore, the heat insulation layer may be made of rubber materials or foam materials.

As illustrated inFIGS. 20-21, according to some embodiments of the present disclosure, one of the fixing member31and the sliding member32is provided with a slide rail314, and the other one of the fixing member31and the sliding member32has a sliding groove323slidably fitted with the slide rail314. That is, the slide rail314may be provided to the fixing member31, and the sliding groove323may be provided in the sliding member32. Or, the sliding groove323may be provided in the fixing member31, and the slide rail314may be provided to the sliding member32. The slide rail314may be slidably fitted with the sliding groove323, such that the fixing member31is fitted with the sliding member32smoothly.

For example, as illustrated inFIG. 21, a part of an upper end of the fixing member31extends upwards to form two spaced slide rails314, and a bottom of the sliding member32is provided with two spaced sliding grooves323. When the sliding member32is assembled with the fixing member31, each slide rail314may extend into the corresponding sliding member323. When the sliding member32extends outwards, the slide rail314and the sliding groove323are slidably fitted with each other. Optionally, a lubricant oil may be added into the sliding groove323such that the slide rail314and the sliding groove323may be fitted with each other smoothly. Optionally, an adhesive layer may be provided on an end face of the sliding member32close to the mounting opening201. In the second position, the sliding member32may be hermetically fitted with the inner wall of the mounting opening201by the adhesive layer, and hence the connection structure between the sealing device30and the mounting opening201is firm.

In the specific example illustrated inFIGS. 28-29, the fixing member31may be fitted with the sliding member32in a nested manner. The fixing member31may include a fit space for the sliding member32, and the sliding member32may include a fit space for the fixing member31. Thus, the fixing member31and the sliding member32are firmly fitted together. Through the above configurations, the fit structure of the fixing member31and the sliding member32is firm, so as to prevent the sliding member32from having a dislocation phenomenon during its sliding process.

As illustrated inFIG. 30, according to some embodiments of the present disclosure, the sealing device30is rotatable with respect to the casing1, and the sealing device30may have a stretched state and a retracted state. In the retracted state, the sealing device30may be received in the receiving groove a, and in the stretched state, the sealing device30may be rotated and stretched out of the casing1. Thus, the connection between the sealing device30and the casing1may be flexible and it is convenient to mount the sealing device30. Specifically, when the window air conditioner100is in transit, the sealing device30may be in the retracted state, and the sealing device30may be received in the receiving groove a. Thereby, the occupied volume of the sealing device30is reduced. When the window air conditioner100is assembled in the mounting opening201, the sealing device30may be adjusted to the stretched state, and the sealing device30may be stretched out with respect to the casing1and closely fitted with the inner wall of the mounting opening201, thus providing a good sealing effect.

As illustrated inFIGS. 30 and 31, according to some embodiments of the present disclosure, the sealing device30is rotatable with respect to the casing1, and the chassis13is provided with an accommodating groove b. The sealing device30has the stretched state and the retracted state. In the retracted state, the sealing device30is accommodated in the accommodating groove b, and in the stretched state, the sealing device30is rotated and stretched out of the casing1. Thereby, the connection between the sealing device30and the casing1is flexible and it is convenient to mount the sealing device30.

For example, as illustrated inFIGS. 30 and 31, two accommodating grooves b are provided in a side wall of chassis13, and the two accommodating grooves b are spaced apart from each other by the receiving groove a of the casing1. One of the accommodating grooves b is arranged in front of the receiving groove a, and the other accommodating groove b is arranged in rear of the receiving groove a. When the sealing device30is in the retracted state, the sealing device30may be accommodated in one of the accommodating grooves b, which may be selected and set according to the actual usage need.

In the following, the window air conditioner100of the present disclosure will be described in detail with reference toFIGS. 25-27 and 30-32by means of a specific embodiment. The window air conditioner100may be used for adjusting an indoor air temperature and an indoor air humidity. It should be understood that the following descriptions are only exemplary, and cannot be construed as a limitation to the present disclosure.

As illustrated inFIG. 32, the wall200is provided with the rectangular mounting opening201, the inner peripheral wall of the mounting opening201is provided with the window frame301, the window300is arranged in the mounting opening201and may be moved up and down with respect to the mounting opening201, and the window air conditioner100is mounted in the mounting opening201.

As illustrated inFIGS. 30-31, the window air conditioner100includes the casing1and the sealing device30. The casing1includes the cabinet10and the chassis13. The outer peripheral wall of the cabinet10is provided with the receiving groove a recessed downwards, and the bottom wall of the receiving groove a is provided with a second sealing member made of silica gel materials. The side wall of the chassis13is provided with two accommodating grooves b, and the two accommodating grooves b are spaced apart from each other by the receiving groove a of the casing1. One of the accommodating grooves b is arranged in front of the receiving groove a, and the other accommodating groove b is arranged in rear of the receiving groove a. The left end and the right end of the casing1each are provided with the sealing device30, and the sealing device30is rotatably connected with the casing1.

As illustrated inFIGS. 25-27, the sealing device30includes the fixing member31and the sliding member32. The fixing member31is connected with the casing1, and the sliding member32is slidably fitted with the fixing member31. The fixing member31is provided with the positioning part312, and the sliding member32is provided with the sliding guide rail322fitted with the positioning part312. The sliding guide rail322has a plurality of positioning grooves3221spaced apart from one another along the length direction of the sliding guide rail322.

As illustrated inFIG. 27, the positioning part312includes the connecting arm3121and the assembling protrusion3122, the connecting arm3121is connected with the fixing member31, and the assembling protrusion3122is connected with the connection arm3121and extends into the positioning groove3221. The assembling protrusion3122has the first inclined surface3122aand the second inclined surface3122b. The included angle α between the first inclined surface3122aand the horizontal plane is 120 degrees, and the included angle β between the second inclined surface3122band the horizontal plane is 90 degrees. The positioning groove3221has the third inclined surface3221aand the fourth inclined surface3221barranged opposite to each other in the left and right direction. The third inclined surface3221ais arranged parallel to the first inclined surface3122a, and the fourth inclined surface3221bis arranged parallel to the second inclined surface3122b.

The positioning part312has the deformed state and the positioned state. When the positioning part312is in the positioned state, the assembling protrusion3122extends into the positioning groove3221. When the sliding member32moves in the direction running away from the fixing member31, the first inclined surface3122aand the third inclined surface3221aare slidably fitted with each other. When the sliding member32moves in the direction approaching the fixing member31, the second inclined surface3122babuts against the fourth inclined surface3221bto restrict the movement of the sliding member32. When the positioning part312is in the deformed state, the connecting arm3121is elastically deformed, such that the assembling protrusion3122may be driven to be separated from the positioning groove3221. In this case, the sliding member32may slide freely in the left and right direction.

The sealing device30has the stretched state and the retracted state. When the sealing device30is in the retracted state, the sealing device30may be received in the receiving groove a, or the sealing device30may also be accommodated in one of the accommodating grooves b. When the sealing device30is in the stretched state, first, the sealing device30rotates with respect to the casing1to a position where the sealing device30is parallel with the horizontal plane of the window frame301, and then, the sliding member32slides outwards with respect to the fixing member31and is closely fitted with the inner wall of the window frame301. The positioning part312allows the sliding member32to keep closely fitted with the window frame301, thus providing a good sealing effect.

According to some embodiments of the present disclosure, as illustrated inFIGS. 31 and 32, the casing1may include the chassis13, and the chassis13may be arranged at the bottom of the cabinet10and placed on the wall200. The window air conditioner100also includes the sealing device30.

As illustrated inFIG. 30-34, the connecting end34of the sealing device30may be rotatably connected with the casing1. The sealing device30may have a retracted state and a sealed state. In the retracted state, the sealing device30may be received in the casing1. In the sealed state, the sealing device30may extend out of the casing1and contact a lower end of the window300, so as to seal the gap between the window300and the mounting opening201.

Specifically, when the window air conditioner100is in transit, the sealing device30may be in the retracted state, and the sealing device30may be received in the casing1, so as to reduce the occupied volume of the sealing device30. When the window air conditioner100is assembled in the mounting opening201, the sealing device30may be adjusted to the sealed state.

Optionally, as illustrated inFIG. 32, the inner wall of the mounting opening201may be provided with the window frame301, and the chassis13may be arranged at the window frame301, so as to improve the sealing effect between the mounting opening201and the window air conditioner100. When the window air conditioner100is mounted, the window300may move downwards with respect to the wall200and extend into the receiving groove a. A left side wall and a right side wall of the window300may be closely fitted with the inner peripheral wall of the window frame301, respectively. Thus, the sealing effect between the window300and the mounting opening201can be improved, and hence the cooling and heating efficiency of the window air conditioner100can be enhanced.

It may be understood that, due to a height difference between the bottom wall of the receiving groove a and the bottom wall of the mounting opening201, after the window300is fitted with the window air conditioner100, there is an assembling gap between the bottom wall of the window300and the bottom wall of the mounting opening201, which thus leads to the cold air leakage of the window air conditioner100and affects the cooling and heating efficiency of the window air conditioner100. The sealing device30may be fitted with the mounting opening201to seal the assembling gap between the window300and the mounting opening201, so as to improve the cooling efficiency of the window air conditioner100.

Specifically, the sealing device30may have the connecting end34and a sealing end35, and the connecting end34of the sealing device30may rotate with respect to the casing1. Thus, the sealing device30may switch between the sealed state and the retracted state. When the sealing device30is in the sealed state, the bottom wall of the sealing device30may be fitted with the bottom wall of the mounting opening201hermetically, and the sealing end35of the sealing device30may be closely fitted with the inner wall of the mounting opening201, so as to seal the assembling gap between the window300and the mounting opening201, thus preventing the cold air leakage of the window air conditioner100.

Optionally, the sealing device30may be a non-metallic part, and the non-metallic part has advantages of light weight as well as easy mounting and dismounting. For example, the sealing device30may be made of non-metallic materials such as plastics, rubber and silica gel. Of course, the sealing device30may also be a metal part, and the metal part has advantages of a firm structure and a long service life. For example, the sealing device30may be a sheet-metal part.

Optionally, the sealing device30may have a detachable connection with the casing1. The sealing device30may be configured to have different models. The different models of the sealing devices30may have different lengths and heights. Thus, an appropriate sealing device30may be selected according to a distance between the casing1and the mounting opening201and a height difference between a bottom wall of the receiving groove a and the inner wall of the mounting opening201, so as to improve the applicability of the sealing device30, thus resulting in a close fit structure between the sealing device30and the mounting opening201and hence providing a good sealing effect.

In the following, the window air conditioner100of the present disclosure will be described in detail with reference toFIGS. 32, 34 and 36by means of a specific embodiment.

As illustrated inFIG. 32, the wall200is provided with a rectangular mounting opening201, the inner peripheral wall of the mounting opening201is provided with a window frame301, and the window300is arranged in the mounting opening201and may be moved up and down with respect to the mounting opening201.

As illustrated inFIGS. 34 and 36, the window air conditioner100includes a casing1and a sealing device30. The casing1includes a cabinet10and a chassis13. The cabinet10is provided with a receiving groove a recessed downwards. The chassis13is disposed at the bottom of the cabinet10and arranged at the window frame301. The left end and the right end of the cabinet10each are provided with the sealing device30, and each sealing device30has a connecting end34and a sealing end35. The connecting end34of the sealing device30is rotatably connected with the cabinet10, and the sealing end35of the sealing device30may be fitted with the inner wall of the window frame301. The sealing device30has a retracted state and a sealed state. When the window air conditioner100is in transit, the sealing device30may be in the retracted state, and the sealing device30may be received in the casing1so as to reduce the occupied volume of the sealing device30. When the window air conditioner100is assembled in the mounting opening201, first, the window300moves downwards and extends into the receiving groove a of the cabinet10, and then, the sealing device30is adjusted from the retracted state to the sealed state. The connecting end34of the sealing device30rotates with respect to the casing1to make the bottom wall and the side wall of the sealing device30closely fitted with the inner peripheral wall of the window frame301, respectively. Thus, a sealed fit between the window air conditioner100and the mounting opening201can be realized, and the cold air leakage of the window air conditioner100can be prevented, so that the cooling and heating efficiency of the window air conditioner100can be improved.

It should be noted that an arrangement manner of the sealing device30is not limited to this, but may be selected and set according to the actual mounting situation. For example, the sealing device30may be provided only on one side of the casing1along the width direction (i.e. the left and right direction as illustrated inFIG. 32), and the other side of the casing1along the width direction may be closely fitted with the inner wall of the mounting opening201. Thus, the sealed fit between the window air conditioner100and the mounting opening201may also be realized.
