The dehumidifying assembly50 includes a condenser <NUM>, an evaporator <NUM>, and a refrigerant circulation line. The condenser <NUM> and the evaporator <NUM> are respectively connected to the refrigerant circulation line. The condenser <NUM> and the evaporator <NUM> are both arranged close to the dehumidifying air outlet <NUM>, and the evaporator <NUM> is closer to the dehumidifying air outlet <NUM> than the condenser <NUM>. The evaporator <NUM> is configured to cover the dehumidifying air outlet <NUM>. As such, the air flow entering the air duct <NUM> from the air inlet <NUM> can be blown out from the dehumidifying air outlet <NUM> after being heated and warmed by the condenser <NUM> and condensed and dehumidified by the evaporator <NUM> in sequence, to complete a dehumidifying process. It should be appreciated that the refrigerant circulation line includes a compressor <NUM>, a throttling device (not shown) and pipelines (not shown) for connecting various components. The compressor <NUM> compresses the refrigerant and form high-temperature gas. After the heat of the high-temperature gas is dissipated passing by the condenser <NUM>, the low-temperature liquid is formed by the throttling device. The low-temperature liquid absorbs heat in the air in the evaporator <NUM> and is evaporated, and then returns to the compressor <NUM> to complete a refrigerant circulation process.

The purifying assembly <NUM> includes a purification filter layer and a mounting assembly (not shown). The mounting assembly is configured to fix the purification filter layer in the housing <NUM> and makes the purification filter layer cover the purifying air outlet <NUM>. As such, the air flow entering the air duct <NUM> from the air inlet <NUM> can be filtered by the purification filter layer before blown out from the purifying air outlet <NUM> to complete the purifying process.

When the fan <NUM> operates regularly, the air outside the housing <NUM> enters the housing <NUM> from the air inlet <NUM>. After circulating in the housing <NUM>, some of the air is dehumidified by the dehumidifying assembly <NUM> to become dry air, and is discharged from the dehumidifying air outlet <NUM>. The other part of the air is purified by the purification module <NUM> to become clean air, and discharged from the purifying air outlet <NUM>. As such, the purification dehumidifier <NUM> simultaneously operates with dehumidification and the air purification.

It should be appreciated that, according to the technical solution of the present invention, the air inlet <NUM>, the dehumidifying air outlet <NUM> and the purifying air outlet <NUM> are arranged on the housing <NUM> of the purification dehumidifier <NUM>. The dehumidifying assembly <NUM> is arranged corresponding to the dehumidifying air outlet <NUM> and the purifying assembly <NUM> is arranged corresponding to the purifying air outlet <NUM>. A part of air entering the housing <NUM> from the air inlet <NUM> can be dehumidified by the dehumidifying assembly <NUM> before changed into dry air and discharged from the dehumidifying air outlet <NUM>. The other part of air entering the housing <NUM> from the air inlet <NUM> can be purified by the purifying assembly <NUM> before changed into clean air and discharged from the purifying air outlet <NUM>. Thus dehumidification and the air purification can be achieved by the purification dehumidifier <NUM>. Namely the purification dehumidifier <NUM> is provided with dehumidification and purification.

As shown in <FIG> and <FIG>, the purification dehumidifier <NUM> further includes an air door assembly which is disposed in the housing <NUM> and corresponds to the dehumidifying air outlet <NUM> or the purifying air outlet <NUM>, configured to open or close the dehumidifying air outlet <NUM> and/or the purifying air outlet <NUM>. It can be appreciated that the air door assembly can open or close the purifying air outlet <NUM> or the dehumidifying air outlet <NUM>, and control an air outlet mode of the purification dehumidifier <NUM>.

A separate purification or a separate dehumidification is provided. When air purification is demanded, the purifying air outlet <NUM> is opened through the air door assembly, and the dehumidifying air outlet <NUM> is set closed. The fan <NUM> starts and external air enters through the air inlet <NUM>. Dust particles and impurities in the air are filtered through the purifying assembly <NUM>, and then flow out through the purifying air outlet <NUM>, to complete the purification. When air dehumidification is demanded, the dehumidifying air outlet <NUM> is opened through the air door assembly, and the purifying air outlet <NUM> is set closed. The fan <NUM> starts, and external air enters through the air inlet <NUM>, dehumidifies the air through the dehumidifying assembly <NUM>, and then flows out through the dehumidifying air outlet <NUM>, to complete the dehumidification. When the purification and dehumidification are simultaneously demanded, both the purifying air outlet <NUM> and the dehumidifying air outlet <NUM> are opened through the air door assembly, and outside air enters the air duct <NUM> through the air inlet <NUM> for purification and dehumidification, and then flows out through the purifying air outlet <NUM> and the dehumidifying air outlet <NUM>.

Further, the air door assembly includes at least one air door structure <NUM> corresponding to the dehumidifying air outlet <NUM> or the purifying air outlet <NUM>.

The air door structure <NUM> includes a driving piece <NUM>, a connecting piece <NUM> and at least two swing blades <NUM>. The connecting piece <NUM> is connected with the driving piece <NUM> and the swing blades <NUM>. The driving piece <NUM> is configured to drive the connecting piece <NUM> to move and drive the swing blades <NUM> to rotate. A gap may be formed between two adjacent swing blades <NUM> to open the dehumidifying air outlet <NUM> or the purifying air outlet <NUM>; or, the two adjacent swing blades <NUM> are abutted to block the dehumidifying air outlet <NUM> or the purifying air outlet <NUM>.

When the purifying air outlet <NUM> and the dehumidifying air outlet <NUM> are opened or closed, the air door structure <NUM> is correspondingly adopted. The driving piece <NUM> drives the connecting piece <NUM> and drives the swing blades <NUM> to rotate, so that gaps are formed between adjacent swing blades <NUM>, and air enters the air duct <NUM> from the gaps; or two adjacent swing blades <NUM> are abutted to block the path of air entering the air duct <NUM>. As such, the air door structure <NUM> is relatively simple in nature, and the purifying air outlet <NUM> and the dehumidifying air outlet <NUM> can be opened or closed conveniently and quickly. In addition, the purifying air outlet <NUM> and the dehumidifying air outlet <NUM> respectively correspond to one air door structure <NUM>. The effect of independently opening or closing the purifying air outlet <NUM> and the dehumidifying air outlet <NUM> can be realized.

The air door structure <NUM> includes a plurality of swing blades <NUM> arranged in the housing <NUM>, and each swing blade <NUM> is elongated and extended in the vertical direction. A plurality of swing blades <NUM> are arranged along the circumferential direction of the housing <NUM>, and each adjacent two swing blades <NUM> can form an arc-shaped door body structure after being spliced, with no gap along the circumferential direction of the door body structure. In addition, both ends of the door structure are respectively provided with an annular partition <NUM>. The upper end of the cylindrical structure is abutted against the inner edge of the annular partition <NUM> located above, and the lower end of the door structure is abutted against the inner edge of the annular partition <NUM> located below. When the driving piece <NUM> drives each swing blade <NUM> to rotate, each adjacent two swing blades <NUM> are separated from each other to form a gap. The corresponding purifying air outlet <NUM> and/or dehumidifying air outlet <NUM> are communicated with the air duct <NUM> in the door body structure, and air can enter the air duct <NUM> through the purifying air outlet <NUM> and/or dehumidifying air outlet <NUM>.

The air door assembly may include a air door structure <NUM> disposed corresponding to the dehumidifying air outlet <NUM>. As such, the air outlet mode of the purification dehumidifier <NUM> can be a combined mode with dehumidification and purification and a separate purification mode. Of course, the air door structure <NUM> can also be arranged corresponding to the purifying air outlet <NUM>, As such, the air outlet mode of the purification dehumidifier <NUM> can be a combined mode with dehumidification and purification, and a separate dehumidification mode. Alternatively, the air door assembly directly comprises two air door structures <NUM>. One air door structure <NUM> is arranged corresponding to the dehumidifying air outlet <NUM> and the other air door structure <NUM> is arranged corresponding to the purifying air outlet <NUM>. As such, the air outlet mode of the purification dehumidifier <NUM> can be a combined mode with dehumidification and purification, a separate dehumidification mode and a separate purification mode.

As shown in <FIG>, the connecting piece <NUM> includes: a first gear <NUM> connected to the driving piece <NUM>, a rack <NUM> meshed with the first gear <NUM>; and at least two second gears <NUM>. each second gear <NUM> is meshed with the gear rack <NUM>. Each of the second gears are engaged with the gear rack, and connected to one end of one of the swing blades. The driving piece is configured to drive the first gear to rotate, the first gear is configured to drive the gear rack to move; the gear rack is configured to drive each of the second gears to rotate; and each of the second gears is configured to rotate to drive one of the swing blades to rotate.

The inner wall of the housing <NUM> is provided with an annular partition <NUM>, which can be provided with an arc-shaped slide rail <NUM>. Correspondingly, the gear rack <NUM> is also arranged in an arc shape, matching with the arc-shaped slide rail <NUM>. The gear rack <NUM> is mounted on the arc-shaped slide rail <NUM>, and can relatively slide along the arc-shaped slide rail <NUM>. In addition, the inner teeth of the arc-shaped rack <NUM> are meshed with each second gear <NUM>. Each second gear <NUM> is sleeved on the rotating shaft of a swing blade <NUM>. Additionally, the outer teeth of the arc-shaped rack <NUM> are meshed with the first gear <NUM>, and the first gear <NUM> is sleeved on the output shaft of the first drive motor <NUM>.

When the driving piece <NUM> operates, its output shaft drives the first gear <NUM> to rotate. The rotation of the first gear <NUM> drives the gear rack <NUM> to slide along the slide rail <NUM>. The sliding of the gear rack <NUM> drives each second gear <NUM> to rotate. The rotation of each second gear <NUM> drives one swing blade <NUM> to rotate, splicing or separating of each adjacent two swing blades <NUM>. As such, the synchronous rotation of each swing blade <NUM> is effectively realized, and the structure is simple and practical.

Further, a guiding inclined surface is provided at a splicing location of one swing blade <NUM> and the other adjacent swing blade <NUM>.

As such, the guiding and buffering of the guiding inclined surface can not only reduce the wear at the splicing location of each adjacent two swing blades <NUM> and prolong the service life of the swing blades <NUM>, but also improve the sealing effect at the splicing location of each adjacent two swing blades <NUM> by abutting the two guiding inclined surfaces and avoid air leakage.

The driving piece <NUM> is a stepmotor. As the precision of each step of the stepmotor is between <NUM>% and <NUM>%, the error of one step will not accumulate to the next. The stepmotor has advanced position precision and movement repeatability.

As shown in <FIG>, the fan <NUM> is a cross-flow fan.

Specifically, the cross-flow fan includes a volute <NUM>, an impeller <NUM> arranged in the volute <NUM>, and a motor <NUM> driving the impeller <NUM> to rotate. The volute <NUM> is positioned in the housing <NUM> and fixed to the side wall of the housing <NUM>. The motor <NUM> is fixed to the upper end of the housing <NUM>. The volute <NUM> has an air inlet side <NUM> and an air outlet side <NUM>. The air inlet side <NUM> is communicated with the air inlet <NUM>, and the air outlet side <NUM> is communicated with the dehumidifying air outlet <NUM> and the purifying air outlet In addition, the impeller <NUM> is extended in the height direction of the housing <NUM>, and the height of the air inlet <NUM> is matched with the height of the impeller <NUM>.

As such, the air inlet area of the purification dehumidifier <NUM> can be effectively increased and the air resistance can be reduced, thereby greatly improving the purifying and dehumidifying capability and the purifying and dehumidifying efficiency of the purification dehumidifier <NUM>. And the purifying and dehumidifying effects of the purification dehumidifier <NUM> are further effectively enhanced. In addition, the application of the cross-flow fan can also enable the air intake of the purification dehumidifier <NUM> more uniform, thus improving the dehumidification effect of the dehumidifying assembly <NUM> and the purification effect of the purifying assembly <NUM>. Additionally, the air flow flows through the impeller <NUM> with two times forces of the blades. The wind force on the air outlet side <NUM> of the volute <NUM> can be more stabilized, thus improving the dehumidification and purification. In addition, the application of cross-flow fan may produces relatively less noise.

As shown in <FIG>, the dehumidifying air outlet <NUM> and the purifying air outlet <NUM> are spaced in the height direction of the housing <NUM>.

Specifically, the housing <NUM> includes a cylinder <NUM> and an end cap <NUM> that covers the upper end of the cylinder <NUM>. The peripheral wall of the cylinder <NUM> is formed with an air inlet <NUM>, a dehumidifying air outlet <NUM>, and a purifying air outlet <NUM>. In which, the air inlet <NUM>, the dehumidifying air outlet <NUM>, and the purifying air outlet <NUM> are all in a grid shape formed by a plurality of small circular holes distributed at intervals. The purifying air outlet <NUM> is located above the dehumidifying air outlet <NUM>, both of which are opposite to the air inlet <NUM>.

Understandably, since the dehumidifying air outlet <NUM> and the purifying air outlet <NUM> are arranged at intervals in the height direction of the housing <NUM>, the dehumidifying air outlet <NUM> and the purifying air outlet <NUM> can respectively occupy the side wall surfaces at different height positions of the housing <NUM>, thereby being beneficial to increasing the dehumidifying air outlet area and the purifying air outlet area. It may also increases the volumes of the condenser <NUM>, the evaporator <NUM> and the purification filter layer, further greatly improving the dehumidification and purification capacity and efficiency, and improving the dehumidification and purification effects.

Further, the air inlet <NUM>, the dehumidifying air outlet <NUM>, and the purifying air outlet <NUM> are all distributed along the circumferential direction of the housing <NUM>.

Specifically, the air inlet <NUM>, the dehumidifying air outlet <NUM>, and the purifying air outlet <NUM> are all distributed along the circumferential direction of the cylinder <NUM>. As such, the dehumidifying assembly50 correspondingly includes a condenser <NUM> and an evaporator <NUM> which are in an arc shape. The condenser <NUM> and the evaporator <NUM> are sequentially provided along the air outlet direction of the dehumidifying air outlet <NUM>. As such, the evaporator <NUM> is positioned outside the condenser <NUM> and covers the dehumidifying air outlet <NUM>. The purifying assembly <NUM> includes a purification filter layer with an arc shape, which covers the purifying air outlet <NUM>.

It can be appreciated that when the fan <NUM> operates, under the drive of the fan <NUM>, a part of the air in the purification dehumidifier <NUM> changes into dry air after passing through the arc-shaped condenser <NUM> and evaporator <NUM>, and the dry air diffuses into the room from the dehumidifying air outlet <NUM>. The dehumidifying air outlet <NUM> is distributed along the circumferential direction of the housing <NUM>, not only effectively increasing the volume of the condenser <NUM> and evaporator <NUM>, but improving the dehumidification capacity, dehumidification efficiency and dehumidification effect of the purification dehumidifier <NUM>. And the air outlet area of the dehumidifying air outlet <NUM> is also increased, so that dehumidified air can fill the room more quickly, further improving the dehumidification effect of the purification dehumidifier <NUM>. Additionally, another part of the air in the purification dehumidifier <NUM> is changed into clean air by the purifying air outlet <NUM> after being acted by the arc shape purifying filter layer and diffused into the room. As such, the purifying air outlet <NUM> is distributed along the circumferential direction of the housing <NUM>, not only effectively increasing the volume of the purifying filter layer, but also improving the purifying capacity, the purifying efficiency and the purifying effect of the purification dehumidifier <NUM>. The air outlet area of the purifying air outlet <NUM> is also increased, and the purified air can fill the room more quickly, thereby further improving the purifying effect of the purification dehumidifier <NUM>. In addition, the air inlet <NUM> being distributed along the circumferential direction of the housing <NUM> can further increase the air inlet area and reduce the air resistance, thereby further improving the purification and dehumidification capability of the purification dehumidifier <NUM> and improving its purification and dehumidification efficiency.

In addition, it can be appreciated that in other embodiments, the housing <NUM> can also be provided as a cavity structure with an oval or polygonal cross section.

Further, the purification filter layer includes an activated carbon filter layer and a high-efficiency air filter layer, which are sequentially provided along the air outlet direction of the purifying air outlet <NUM>. As such, the air blown out from the purifying air outlet <NUM> can pass through the activated carbon filter layer and the high-efficiency air filter layer successively before being blown out, effectively improving the air purification effect.

It should be appreciated that, the activated carbon filter layer can utilize porous activated carbon to adsorb one or more substances in the air on its surface and remove them. The removed objects include soluble organic substances, microorganisms, viruses and a certain amount of heavy metals. It may also decolorize, deodorize and purify the air. The activated carbon lattice can form developed pores with different shapes and sizes, thus greatly increasing the specific surface area and improving the adsorption capacity.

High efficiency particulate air filter (HEPA) is mainly used to collect dust particles and various suspended substances below <NUM> micrometer. The filter layer of the high efficiency air filter is featured that air can pass through, but fine particles is blocked. Its count transmittance for particles with particle diameter ≥<NUM> micrometer is ≤<NUM>% (i.e. efficiency ≥<NUM>%), and it is the most effective filter medium for pollutants such as smoke, dust and bacteria. The filter layer of the high-efficiency air filter can be a PP filter paper, a glass fiber, a composite PP-PET filter paper, a meltblown polyester nonwoven fabric or a meltblown glass fiber, etc..

Therefore, through the filtration of the active carbon filter layer and the high-efficiency air filter layer, organic pollutants and particles in the air can be purified, thus improving the purification effect and the air quality.

It should be appreciated that the shape, size and arrangement of the condenser <NUM> and the evaporator <NUM> need to be matched with that of the dehumidifying air outlet <NUM> to achieve the optimal dehumidification effect. Additionally, the shape, size and arrangement of the purification filter layer need to be matched with that of the purifying air outlet <NUM> to achieve the optimal purification effect. In addition, both the condenser <NUM> and the evaporator <NUM> can be provided with a plurality of heat exchange fins to increase the heat exchange area and improve the heat exchange efficiency.

Referring further to <FIG>, the dehumidifying assembly <NUM> further includes a water tank <NUM> and a water receiving tray <NUM> disposed in the housing <NUM>. The water receiving tray <NUM> is located below the evaporator <NUM> and is communicated with the water tank <NUM>. By arranging the water receiving tray <NUM> below the evaporator <NUM>, the water receiving tray <NUM> can receive the condensed water flowing down from the surface of the evaporator <NUM>, and by communicating the water receiving tray <NUM> with the water tank <NUM>, the condensed water can be better guided into the water tank <NUM> for collection. The leakage or overflow of the condensed water can be thus avoid of causing adverse effects on the internal circuit of the purification dehumidifier <NUM>. In addition, the water tank <NUM> may also be provided with a liquid level detection device, which is connected with the main controller of the purification dehumidifier <NUM>. When the liquid level detection device detects that the water level in the water tank <NUM> reaches a preset threshold, it transmits an alarm signal to the main controller, and the main controller sends out a prompt tone or message. As such, the user can be reminded of leading out the water flow in the water tank <NUM>. The water flow in the water tank <NUM> can be led out in two ways: one way is to arrange a water outlet pipe on which a valve is arranged to control the outflow of water. The other option is that the housing <NUM> is provided with an avoiding opening, the avoiding opening is provided with a movable door <NUM>, and the water tank <NUM> is arranged in the housing <NUM> and corresponding to the avoiding opening. By opening the movable door <NUM>, the water tank <NUM> is taken out from the avoiding opening, and the water is poured out.

Further, the compressor <NUM> is located below the condenser <NUM> and the evaporator <NUM>, and provided opposite to the water tank <NUM>. The compressor <NUM> is arranged below the condenser <NUM> and the evaporator <NUM> to facilitate the communication of pipelines. Since both the water tank <NUM> and the compressor <NUM> are heavy components, the installation of the purification dehumidifier <NUM> can be more stable by arranging both the water tank <NUM> and the compressor <NUM> at the lower end of the housing <NUM>. Additionally, arranging the water tank <NUM> opposite to the compressor <NUM> can save the arrangement space inside the housing <NUM>, so that the overall structural layout of the purification dehumidifier <NUM> is more compact.

The purification dehumidifier <NUM> may further include a first air door assembly (not shown) and a second air door assembly (not shown), wherein the first air door assembly is provided corresponding to the purifying air outlet <NUM> to open or close the air flow passage at the purifying air outlet <NUM>, while the second air door assembly is provided corresponding to the dehumidifying air outlet <NUM> to open or close the air flow passage at the dehumidifying air outlet <NUM>. In addition, the purification dehumidifier <NUM> may also be provided with an air quality monitoring device, including a particle sensor, a humidity sensor, etc. The air quality monitoring device is electrically connected with the main controller, and when more dust in the air is detected, the main controller controls the first air door assembly to open the airflow channel at the purifying air outlet <NUM> to purify indoor air. When the humidity in the air is detected high, the main controller controls the second air door assembly to open the air flow passage at the dehumidifying air outlet <NUM> to dehumidify the air indoor. Of course, when more dust and moisture are simultaneously detected, the main controller controls the two air door assemblies to open the air flow passages at the purifying air outlet <NUM> and the dehumidifying air outlet <NUM> respectively to purify and dehumidify the air.
