With the development of technology, the air conditioner has gradually become an indispensable home appliance in the daily life of people, and people's requirements on differentiation and multi-function are increasing. Currently, the movable air conditioner is generally provided with a heat exchanger and a volute inside the housing, and a heat exchange air channel communicating with the heat exchanger is formed in the volute. In the related art, the volute is directly screwed and fixed in the housing through screws, which has the defect that the installation is unstable.

In view of the above, the present application provides a movable air conditioner, and <FIG> are specific embodiments of the movable air conditioner provided by the present application.

The middle partition plate <NUM> is arranged in the housing <NUM>. The volute <NUM> is arranged in the housing <NUM>. The volute <NUM> and the middle partition plate <NUM> are provided with a fixing structure, and the fixing structure is arranged around the volute <NUM> to fix the volute <NUM> on the middle partition plate <NUM>.

According to the embodiments provided by the invention, the middle partition plate <NUM> can limit a downward movement of the volute <NUM>. By arranging the fixing structure around the volute <NUM>, the volute <NUM> can be restricted to move in a circumferential direction, thus, good fixation of the volute <NUM> in the housing <NUM> is achieved, and the installation stability of the volute <NUM> is improved.

It should be noted that, in this embodiment, the middle partition plate <NUM> is arranged in a middle part of the housing <NUM>, so as to divide the housing <NUM> into an indoor side cavity and an outdoor side cavity which are distributed along an up-down direction. The movable air conditioner includes an indoor side heat exchanger <NUM>, an outdoor side heat exchanger (not shown in the figures) and an outdoor heat exchanging air duct (not labeled in the figures). The indoor side heat exchanger <NUM> is arranged in the indoor side cavity. An indoor side heat exchanging air duct is formed in the volute <NUM> and includes an air inlet and an air outlet. The orientation of each of the air inlet and the air outlet can be any one in various orientations, but in this embodiment, the air inlet is optionally formed on one side of the volute <NUM> close to the indoor side heat exchanger <NUM>, and communicates with the indoor side heat exchanger <NUM>, and the air outlet is formed at an upper end of the volute <NUM>. Therefore, a length of the indoor side heat exchanging air duct is prolonged. The outdoor side heat exchanger is arranged in the outdoor side cavity, the outdoor side heat exchanging air duct is communicated with the outdoor side heat exchanger and the indoor side heat exchanging air duct. The specific heat exchange principle of the movable air conditioner using the indoor side heat exchanger <NUM> and the outdoor side heat exchanger can make reference to the related art, and is not described in detail here.

In addition, the fixing structure is arranged around the volute <NUM> in this design, that is, the fixing structure is arranged at a periphery of the volute <NUM> along a circumferential direction of the middle partition plate <NUM>, and the fixing structure can be of a structure arranged along a circumferential direction of the middle partition plate <NUM> without an interruption. In one embodiment, the fixing structure is specifically shown as an annular convex rib, and the annular convex rib is arranged on the periphery of the volute <NUM>. The annular convex rib and the middle partition plate <NUM> cooperate to define a mounting groove. An inner size of the annular convex rib is matched with an outer contour size of a corresponding position of the volute <NUM>, so that the mounting groove can just clamp the volute <NUM> and connect with the volute <NUM>, and the fixing and mounting of the volute <NUM> are achieved. Of course, the fixing structure can be of a structure arranged along the circumferential direction of the middle partition plate <NUM> with one or more interruptions. In another embodiment, the fixing structure is specifically shown as a plurality of convex blocks, and the plurality of convex blocks are distributed on the periphery of the volute <NUM>, so that good limiting of the volute <NUM> can be achieved, and the advantages of being light and saving materials are also achieved.

Further, referring to <FIG>, in this embodiment, the volute <NUM> includes an air duct plate <NUM>, the air duct plate <NUM> is formed on one side of the volute <NUM> away from the indoor side heat exchanger <NUM>, that is, the side of the volute <NUM> away from the air inlet. The air duct plate <NUM> is in an arc shape, so that a large space is formed in the volute <NUM>, and the indoor side heat exchanging air duct can be bent, and the heat exchanging effect can be enhanced. The fixing structure includes a supporting base <NUM> protruded from the middle partition plate <NUM>, the supporting base <NUM> is provided below the air duct plate <NUM> and abuts against the air duct plate <NUM>, thereby restricting the movement of the volute <NUM> in a direction away from the indoor side heat exchanger <NUM>. Similarly, the supporting base <NUM> can be of a structure arranged along a length direction of the volute <NUM> without an interruption or with one or more interruptions. When the supporting base <NUM> is arranged along the length direction of the volute <NUM> without an interruption, the supporting base <NUM> can extend along the length direction of the volute <NUM> to abut against a whole lower end of the volute <NUM>, so as to enlarge an abutment area between the supporting base <NUM> and the volute <NUM>. Of course, the supporting base <NUM> can extend along the length direction of the volute <NUM> to a part of the lower end of the volute <NUM>. At this time, since the air duct plate <NUM> is in an arc shape, a remaining part of a lower end of the air duct plate <NUM> is not abutted against the supporting base <NUM>, and is suspended above the middle partition plate <NUM>. Therefore, one or more cushion blocks (not shown in the figures) can be convexly arranged at the remaining section of the middle partition plate <NUM> to fill space corresponding to the suspended position, so as to ensure the balance and stability of the volute <NUM> on the middle partition plate <NUM>.

Next, in this embodiment, an upper end of the supporting base <NUM> is provided with an abutting surface abutting against an outer wall surface of the air duct plate <NUM>. A shape of the abutting surface is matched with a shape of the outer wall surface of the air duct plate <NUM>. Based on the above, the air duct plate <NUM> in this embodiment is preferably in an arc shape, that is, the outer wall surface of the air duct plate <NUM> abutting against the abutting surface is in a convex arc surface shape. In this case, the abutting surface can be provided in a concave arc surface shape, and the abutment area between the supporting base <NUM> and the air duct plate <NUM> can be increased with the male-female fitting between the convex arc surface and the concave arc surface.

In addition, in this embodiment, the volute <NUM> further includes a wind deflector bottom plate <NUM>, the wind deflector bottom plate <NUM> extends from the lower end of the air duct plate <NUM> to be away from the air duct plate <NUM>. A shape of the wind deflector bottom plate <NUM> is adapted to a shape of a corresponding part of the middle partition plate <NUM>, for example, when the middle partition plate <NUM> is in a flat plate shape at this part, the wind deflector bottom plate <NUM> is in a flat plate shape parallel to or approximately parallel to the middle partition plate <NUM>. The fixing structure further includes a first blocking rib <NUM> protruded from the middle partition plate <NUM>. The first blocking rib <NUM> is provided on one side of the wind deflector bottom plate <NUM> away from the air duct plate <NUM>, and abuts against a side edge of the wind deflector bottom plate <NUM> away from the air duct plate <NUM>. An extending direction of the first blocking rib <NUM> is identical to an extending direction of the side edge of the wind deflector bottom plate <NUM> away from the air duct plate <NUM>, and the first blocking rib <NUM> may be exactly equal to or slightly higher than the side edge of the wind deflector bottom plate <NUM> in height. In this embodiment, the first blocking rib <NUM> is arranged to cooperate with the supporting base <NUM>, so that the volute <NUM> can be effectively restricted to move close to or away from the indoor side heat exchanger <NUM>.

In order to enlarge the space in the volute <NUM> to increase an air inlet amount, referring to <FIG>, in this embodiment, the volute <NUM> further includes an extension plate <NUM> arranged at the lower end of the air duct plate <NUM>. The extension plate <NUM> extends downwards, and the wind deflector bottom plate <NUM> is arranged at a lower end of the extension plate <NUM>. Further, a plurality of reinforcing ribs <NUM> can be provided at the extension plate <NUM>. The plurality of reinforcing ribs <NUM> extend along a width direction of the extension plate <NUM>, and are arranged at intervals along a length direction of the extension plate <NUM>, which helps to enhance the connection strength of the extension plate <NUM>.

In addition, referring to <FIG> and <FIG>, in this embodiment, the middle partition plate <NUM> is provided with a water guide groove <NUM> which is obliquely arranged. The water guide groove <NUM> is arranged above the outdoor side heat exchanger. The first blocking rib <NUM> includes two sections distributed on two sides of the water guide groove <NUM>. An air leakage gap is formed between the two sections of the first blocking rib <NUM>, and a water blocking ridge <NUM> is formed on the wind deflector bottom plate <NUM> corresponding to the air leakage gap. The water guide groove <NUM> is provided with a plurality of water falling holes <NUM> communicated with the indoor side cavity and the outdoor side cavity. The plurality of water falling holes <NUM> are arranged at intervals along a length direction of the water guide groove <NUM>, the water guide groove <NUM> is arranged below the volute <NUM>, and is used for converging condensate water generated in the indoor side cavity to be output to the outdoor side cavity. The inclined water guide groove <NUM> helps to expand an area range of the water guide groove <NUM> in the length direction of the volute <NUM>, thereby facilitating the rapid drainage. Then, the water blocking ridge <NUM> correspondingly covers at least part of a notch of the water guide groove <NUM>, so that the condensate water in the water guide groove <NUM> can be prevented from being reversely splashed into the volute <NUM>. A length of the water blocking ridge <NUM> can be set to be equal to a length of the air leakage gap, so that when the volute <NUM> is installed on the middle partition plate <NUM>, the air leakage gap is exactly matched with the water blocking ridge <NUM> in a male-female fitting manner to jointly form a watertight water blocking rib. The water blocking rib can not only block the condensate water from entering the volute <NUM>, but also strengthen the limiting effect of the first blocking rib <NUM> on the volute <NUM>.

In this embodiment, the water blocking ridge <NUM> includes a wind deflector <NUM> arranged on the side edge of the wind deflector bottom plate <NUM>, and the wind deflector <NUM> protrudes downwards from the wind deflector bottom plate <NUM>. That is, the wind deflector <NUM> protrudes from the wind deflector bottom plate <NUM> until being substantially flush with the lower end of the wind deflector bottom plate <NUM>. The wind deflector <NUM> can block wind from entering the lower end of the wind deflector bottom plate <NUM>, while does not affect the condensate water entering the water guide groove <NUM> from a position under the water blocking ridge <NUM>.

Based on the above, referring to <FIG> and <FIG>, in this embodiment, at least one second blocking rib <NUM> is further provided on the middle partition plate <NUM>, the at least one second blocking rib <NUM> is disposed on one side of the first blocking rib <NUM> facing away from the volute <NUM>, and an extending direction of each second blocking rib <NUM> may be identical to that of the first blocking rib <NUM>, and each second blocking rib <NUM> is provided with an opening for the condensate water to flow to the water guide groove <NUM>. Two adjacent second blocking ribs <NUM> or the first blocking rib <NUM> and an adjacent second blocking rib form a drainage groove to allow the condensate water to flow through. The drainage groove formed between the first blocking rib <NUM> and the second blocking rib <NUM> is taken as an example, the drainage groove is arranged to be gradually inclined downwards in a direction towards the water guide groove <NUM>, so that the condensate water in the drainage groove is conveniently and thoroughly drained into the water guide groove <NUM>. In addition, the opening on the second blocking rib <NUM> can be arranged corresponding to the water guide groove <NUM>. A flow shunting rib <NUM> can be convexly arranged between the opening and the air leakage gap, and the flow shunting rib <NUM> can be used for dispersing the condensate water from the opening to the water guide groove <NUM>, so that the condensate water is dispersed in the water guide groove <NUM>, and not accumulated at a certain water falling hole <NUM> in the water guide groove <NUM> to affect the drainage efficiency.

Referring to <FIG>, <FIG> and <FIG>, in this embodiment, the volute <NUM> further includes two side plates <NUM>, the two side plates <NUM> are distributed on two sides of the air duct plate <NUM>, the two sides of the air duct plate <NUM> refer to two sides of the air duct plate <NUM> corresponding to the length direction of the volute <NUM>. The two side plates <NUM>, the air duct plate <NUM>, the extension plate <NUM> and the wind deflector bottom plate <NUM> cooperate to form the volute <NUM>. The side plate <NUM> is formed with a first protrusion <NUM> protruded away from the wind deflector bottom plate <NUM>. The fixing structure further includes a second protrusion <NUM> protruded from the middle partition plate <NUM>. The second protrusion <NUM> abuts against the first protrusion <NUM>. It should be noted that the specific forms of the first protrusion <NUM> and the second protrusion <NUM> are not limited in the present design, for example, the first protrusion <NUM> may be protruded toward the indoor side heat exchanger <NUM>, and the second protrusion <NUM> abuts against an outer side wall of the first protrusion <NUM>, or the first protrusion <NUM> may protrude from the side plate <NUM> along the length direction of the volute <NUM>, and form a reinforcing plate <NUM> which is substantially parallel to an edge of a port of the air inlet. At this time, the second protrusion <NUM> is provided with a clamping groove, and the clamping groove is in fit with at least part of a side edge of the first protrusion <NUM> in a male-female fitting manner. In addition, according to different practical applications, the first protrusion <NUM> may be formed on at least one of the two side plates <NUM>, especially when there are two first protrusion <NUM> corresponding to the two side plates <NUM>, the limiting to the volute <NUM> in the length direction of the volute <NUM> can be reinforced.

When at least one of the two side plates <NUM> is protruded from the wind deflector bottom plate <NUM> in a direction away from the air duct plate <NUM>, a spigot is defined between the the side plate <NUM> and the wind deflector bottom plate <NUM>, and the first blocking rib <NUM> is provided in the spigot so as to abut against the side edge of the wind deflector bottom plate <NUM> away from the air duct plate <NUM> as well as to abut against the side plate <NUM>. Further, referring to <FIG>, <FIG> and <FIG>. In this embodiment, the side plate <NUM> is provided with a positioning groove <NUM>, and the first blocking rib <NUM> is clamped in the positioning groove <NUM>. Compared with the design of the first blocking rib <NUM> directly abutting against the side plate <NUM>, by means of the cooperation of the first blocking rib <NUM> and the positioning groove <NUM>, the connection strength between the first blocking rib <NUM> and the side plate <NUM> is enhanced, and thus the limiting effect of the first blocking rib <NUM> on the volute <NUM> is enhanced.

In order to further enhance the limiting of the fixing structure to the volute <NUM> along the length direction of the volute <NUM>, referring to <FIG>, in this embodiment, the fixing structure further includes a side blocking protrusion <NUM> provided on the middle partition plate <NUM>, the side blocking protrusion <NUM> is located on one side of the side plate <NUM> and abuts against the side plate <NUM>. The side blocking protrusion <NUM> may correspond to at least one of the two side plates <NUM>. Further, there may be a plurality of side blocking protrusions <NUM> corresponding to each side plate <NUM>, and the plurality of side blocking protrusions <NUM> are arranged at intervals along the width direction of the volute <NUM>. It should be noted that the specific form of each side blocking protrusion <NUM> is not limited in this design. In one embodiment, the side blocking protrusion <NUM> can be a block, so that one side wall of the side blocking protrusion <NUM> directly abuts against the corresponding side plate <NUM>. Or in another embodiment, the side plate <NUM> can be provided with a limiting groove, and the side blocking protrusion <NUM> is engaged with the limiting groove in a male-female fitting manner. Or liking that in this embodiment, the side plate <NUM> can be provided with a limiting rib, the side blocking protrusion <NUM> is provided with a groove at a position corresponding to the limiting rib, and the groove is engaged with the limiting rib in a male-female fitting manner, so that an abutment area between the volute <NUM> and the side blocking protrusion <NUM> is enlarged, and the mounting stability between the volute <NUM> and the side blocking protrusion <NUM> is ensured.

In this embodiment, the fixing structure further includes a connecting column <NUM>.

Specifically, a mounting hole can be formed in the connecting column <NUM>, a threaded hole can be formed on the volute <NUM> corresponding to the mounting hole. The fixing structure further includes a threaded member, and the threaded member passes through the mounting hole and then is connected with the threaded hole through threads, so that the volute <NUM> is fixedly mounted on the middle partition plate <NUM>. It should be noted that, according to actual requirements, the connecting column <NUM> in the present design may be disposed at any position along the circumferential direction of the volute <NUM>, and there may be one or more connecting columns <NUM> according to actual requirements, or a plurality of mounting holes may be provided on one connecting column <NUM>. In addition, when the threaded hole is set at a higher position of the volute <NUM>, a raised portion can be provided on the middle partition plate <NUM>, then the connecting column <NUM> is convexly arranged on the raised portion, thereby avoiding to affect the connection strength of the connecting column <NUM> by directly setting a longer connecting column <NUM> on the volute <NUM>.

It should be noted that the air duct plate <NUM>, the wind deflector bottom plate <NUM>, the side plate <NUM> and the like described above do not constitute a limitation on the specific shape of the volute <NUM>. Taking the side plate <NUM> as an example, the side plate <NUM> may be directly connected to the wind deflector bottom plate <NUM>, or as shown in <FIG>, the side plate <NUM> is connected to the wind deflector bottom plate <NUM> through a step portion, which not only helps to form a mounting structure for mounting other components in the volute <NUM>, but also increases the connection strength between the side plate <NUM> and the wind deflector bottom plate <NUM>.
