The floor type equipment not only has large size but also needs to occupy very large ground installation space, and is mainly suitable for villa or scene with independent equipment room, and is difficult to install and adapt in the flat.

[0004] For the existing dehumidification fresh air machine, it usually adopts wall hanging or ceiling installation. For wall hanging installation, the installation length requirement is more than 1.5 meters; for ceiling installation, the installation thickness is more than 350 mm, and the longitudinal depth is more than 650 mm. For ordinary flat ceiling, the ceiling height is usually less than 350 mm, so the dehumidification fresh air machine is difficult to be completely installed above the ceiling. For the standard cabinet, the longitudinal depth is not more than 600 mm, and in the extreme case, the general longitudinal depth is also not more than 650 mm, so the dehumidification fresh air machine is also difficult to be directly installed in the existing cabinet. Therefore, the current dehumidification fresh air machine is also difficult to popularize and apply in the flat scene. In addition, taking the installation of the dehumidification fresh air machine on the balcony as an example, since the installation length of the dehumidification fresh air machine is required to be more than 1.5 meters, and the depth size of the existing balcony (especially the service balcony for placing washing machine and drying clothes) is mostly within 1.5 meters, and even the longitudinal depth of some balconies is within 1.2 meters, therefore, the dehumidification fresh air machine is difficult to be installed on the balcony in terms of installation thickness, longitudinal depth size or installation length.

[0005] Overall, how to install the indoor unit of the air treatment system in the limited space of the flat scene, so that the indoor treatment system can be applied in the flat scene is an urgent improvement direction. UTILITY MODEL CONTENT

The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0102] The utility model provides a kind of indoor air treatment device, air treatment system's indoor unit can be installed in the space of the limited space of flat scene, so that indoor processing system can be applied in flat scene, and when using, it can also achieve better mute effect.

[0103] Please refer to Figures 1 to 5In the embodiments of the present application, an indoor air treatment device 200 can include an air treatment module 4 and an air supply module 5 arranged separately, the air supply module 5 is arranged at least partially above a ceiling 6, and the air treatment module 4 is arranged below the ceiling 6 in a wall-mounted manner. The air treatment module 4 has a first housing 40 in which a heat exchanger is arranged, the heat exchanger is used for directly and / or indirectly treating indoor air, the air supply module 5 has a second housing 50 in which a fan 23 is arranged, an air inlet and an air outlet 413 are arranged on the first housing 40, and an air inlet 501 is arranged on the second housing 50, the air outlet 413 and the air inlet 501 are connected in communication through a pipeline.

[0104] In the embodiments of the present application, the indoor air treatment device 200 can include an air treatment module 4 and an air supply module 5 arranged separately. When the air treatment module 4 and the air supply module 5 are arranged separately, the original indoor air treatment device 200 can be divided into two relatively smaller sizes from a larger size, and the air treatment module 4 and the air supply module 5 can be installed flexibly in the installation space suitable for the flat scene, thereby facilitating the installation and application of the indoor air treatment device 200 in the flat scene with limited installation space.

[0105] As shown in Figure 2 For the application scene provided with the ceiling 6, the air supply module 5 can be arranged at the upper part of the ceiling 6, and the air treatment module 4 can be arranged at the lower part of the ceiling 6 in a wall-mounted manner. For the air supply module 5, the second housing 50 is provided with the fan 23. Since the air supply module 5 is provided with the fan 23, the fan 23 will generate a certain noise when working. When the air supply module 5 is arranged at least partially above the ceiling 6, the fan 23 can be arranged away from the user, and the noise generated by the fan 23 when working can be isolated by the ceiling 6. Not only can the indoor air treatment device 200 be installed and applied in the flat scene, but also the indoor air treatment device 200 can achieve a better silent effect when working, thereby ensuring a better user experience.

[0106] For flat layer, its installation space is relatively limited, usually without separate equipment room, the position capable of installing the indoor air treatment device 200 is very limited. And for flat layer scene, users want to efficiently use the area in the room, and do not want to install a separate machine occupying a large space in the room. Therefore, one of the positions where the indoor air treatment device 200 can be installed is the balcony 600. Therefore, in the present embodiment, the indoor air treatment device 200 installed on the balcony 600 is mainly taken as an example for illustration. Of course, in the present embodiment, it is also not excluded that the indoor air treatment device 200 can be installed in other scenarios.

[0107] When the indoor air treatment device 200 is installed on the balcony 600, the air supply module 5 can be installed above the ceiling 6 of the balcony 600, and the air treatment module 4 can be installed on the side wall of the balcony 600 by wall hanging. In order to install the appearance, the air treatment module 4 can be hiddenly installed in the cabinet of the balcony 600.

[0108] In the present embodiment, the air treatment module 4 has a first shell 40, which is mainly used for installing core functional components such as heat exchangers. The first shell 40 is provided with an air inlet and an air outlet 413. The air supply module 5 has a second shell 50, which is mainly used for installing the fan 23. The second shell 50 is provided with an air outlet 502 and an air inlet 501. The air outlet 413 of the first shell 40 is connected to the air inlet 501 of the second shell 50 through a pipeline, and after the fan 23 is started, the air flowing into the first shell 40 through the air inlet can flow into the second shell 50 through the air outlet 413 of the first shell 40 and the air inlet 501 of the second shell 50.

[0109] In one embodiment, the first shell 40 has a transverse dimension and a longitudinal dimension in the transverse direction and the longitudinal direction, and the transverse dimension is greater than the longitudinal dimension.

[0110] In the present embodiment, the first shell 40 can be a hollow box structure as a whole, and of course the first shell can also have other regular or irregular structures, and in the present embodiment, the first shell 40 is mainly taken as a cuboid for illustration.

[0111] The first shell 40 has a transverse dimension (i.e. length dimension) in the transverse direction and a longitudinal dimension (i.e. height dimension) in the longitudinal direction, wherein the transverse dimension is greater than the longitudinal dimension. When the air treatment module 4 is arranged horizontally, the transverse dimension extends along the horizontal direction X and the longitudinal dimension extends along the height direction Y, so as to improve the ground clearance of the air treatment module 4, so that the height of the air treatment module 4 from the ground does not easily interfere with the user's head. When the air treatment module 4 has a higher ground clearance, corresponding devices such as a basin and a washing machine can be arranged below the air treatment module 4, which can be operated and used below the air treatment module 4, so that the space below the air treatment module 4 can be effectively utilized.

[0115] The first heat exchanger 21 and the second heat exchanger 22 are arranged transversely in the first shell 40, specifically the thickness direction of the first heat exchanger 21 and the thickness direction of the second heat exchanger 22 are arranged along the transverse dimension of the air handling module 4, so that the transverse dimension of the air handling module 4 is utilized to the maximum extent to arrange the core components in the first shell 40 of the air handling module 4. In addition, the transverse dimension of the air handling module 4 can also be effectively controlled so as not to be too large, thereby improving the adaptability of the air handling module 4. Specifically, the transverse dimension of the air handling module 4 (i.e. the length dimension of the first shell 40) can be controlled to be within 900 mm, so that it can be adapted to the depth dimension of all balconies 600.

[0116] In one embodiment, the first refrigerant flow channel 211 of the first heat exchanger 21 has a first refrigerant inlet and a first refrigerant outlet, the second refrigerant flow channel 221 of the second heat exchanger 22 has a second refrigerant inlet and a second refrigerant outlet, the second heat exchanger 22 includes a water flow channel 212 having a water flow channel 212 inlet and a water flow channel 212 outlet, the air inlet includes a fresh air inlet 411 and a return air inlet 412, the fresh air inlet 411 and the exhaust air outlet 413 are located on the top wall 403 of the first shell 40, the first refrigerant flow channel 211 and the second refrigerant flow channel 221 are connected to the refrigerant flow channel of the outdoor unit 100, the first refrigerant flow channel 211, the second refrigerant flow channel 221 and the water flow channel 212 are arranged through the top wall 403 of the first shell 40 or the first refrigerant flow channel 211, the second refrigerant flow channel 221 and the water flow channel 212 are arranged inside the first shell 40 and the refrigerant flow channel of the outdoor unit 100 is arranged through the top wall 403 of the first shell 40, and the return air inlet 412 is arranged on the side wall or the bottom wall 404 of the first shell 40.

[0117] In the present embodiment, the first heat exchanger 21 can include a plate-shaped body, the first refrigerant flow channel 211 of the first heat exchanger 21 includes a first internal refrigerant flow channel arranged inside the plate-shaped body, a first refrigerant inlet and a first refrigerant outlet arranged on the plate-shaped body, and a first external refrigerant flow channel connected to the first internal refrigerant flow channel through the first refrigerant inlet and the second refrigerant outlet. The first refrigerant inlet can be in the form of a refrigerant connector for connecting a refrigerant pipe, and the first refrigerant outlet can also be in the form of a refrigerant connector for connecting a refrigerant pipe.

[0118] The second heat exchanger 22 can include a heat exchange body for flowing refrigerant, which is substantially plate-shaped. The second refrigerant flow channel 221 of the second heat exchanger 22 includes a second internal refrigerant flow channel arranged inside the heat exchange body, a second refrigerant inlet and a second refrigerant outlet arranged on the heat exchange body, and a second external refrigerant flow channel in communication with the second internal refrigerant flow channel through the second refrigerant inlet and the second refrigerant outlet. The second refrigerant inlet can be in the form of a refrigerant joint for connecting a refrigerant pipe, and the second refrigerant outlet can also be in the form of a refrigerant joint for connecting a refrigerant pipe.

[0119] The first refrigerant inlet and the second refrigerant inlet can be connected to a first merging portion (for example, a tee joint) through a first external refrigerant pipe, and then connected to the outdoor unit 100 through a refrigerant pipe (for example, a first refrigerant connecting pipe 61 connected to the refrigerant inlet 11 of the outdoor unit 100, and a second refrigerant connecting pipe 62 connected to the refrigerant outlet 12 of the outdoor unit 100) of the outdoor unit 100. The second refrigerant outlet and the second refrigerant outlet can also be connected to a second merging portion (for example, a tee joint) through a second external refrigerant pipe, and then connected to the outdoor unit 100 through the refrigerant pipe (the first refrigerant connecting pipe 61 and the second refrigerant connecting pipe 62) of the outdoor unit 100.

One group of openings is used for passing the first refrigerant flow channel 211, and the other group of openings is used for passing the second refrigerant flow channel 221. When the first refrigerant flow channel 211 and the second refrigerant flow channel 221 pass through the top wall 403 of the first shell 40 and are connected to the refrigerant flow channel of the outdoor unit 100, it is beneficial to connect and maintain the refrigerant pipe outside the first shell 40.

[0122] In the embodiment, the first shell 40 has a height space of the ceiling 6 on the top wall 403. When the fresh air outlet 411 and the exhaust air outlet 413 are located on the top wall 403 of the first shell 40, the first refrigerant flow channel 211, the second refrigerant flow channel 221, and the water flow channel 212 are arranged through the top wall 403 of the first shell 40 or are arranged in the first shell 40, and the refrigerant flow channel of the outdoor unit 100 is arranged through the top wall 403 of the first shell 40, the ceiling 6 space can be used for pipe connection, and the refrigerant pipe, the water pipe, and the air pipe can be arranged in the ceiling 6 space. In addition, the pipe connection in the ceiling 6 space is beneficial to the protection of the pipes and ensures the installation aesthetics.

[0123] Considering that the installation space in a flat environment is very limited, especially the transverse dimension space and the lower ground clearance, there is no extra space that can be used. If the opening required for the external pipe is arranged on the left / right side wall of the first shell 40, the transverse dimension of the first shell 40 may be too large to be arranged in a flat environment. If the opening required for the external pipe is arranged on the front / rear side wall of the first shell 40, the size of the first shell 40 in the front-rear direction will be increased, which is depressing and requires a higher longitudinal depth of the cabinet for the cabinet scene. If the opening required for the external pipe is arranged on the bottom wall 404 of the first shell 40, the ground clearance of the air handling module 4 will be reduced, which will interfere with the user's head and affect the normal use of the equipment below the air handling module 4. Therefore, the pipe arrangement in the embodiment can maximize the optimization of the space arrangement of the first shell 40 below the ceiling 6 and maximize the installation adaptability of the first shell 40.

[0124] In the following, the specific arrangements of the above-mentioned parts will be introduced respectively.

[0125] In the embodiment, the water in the water flow channel 212 can exchange heat with the refrigerant in the first refrigerant flow channel 211, and the cooled water or the heated water after the heat exchange with the refrigerant in the first refrigerant flow channel 211 can be supplied to the indoor radiation terminal 32. The indoor radiation terminal 32 releases cold or heat to the indoor to adjust the indoor temperature. The water flow channel 212 has a water flow channel 212 inlet and a water flow channel 212 outlet. A first water channel can be arranged between the water flow channel 212 inlet and the plate-shaped body, and a water pump 213 can be arranged on the first water channel. The water pump 213 is used to provide driving force for water circulation. The water flow channel 212 inlet can be in the form of a water pipe joint and is used to connect a water return pipe.

[0126] A second water passage can be provided between the outlet of the water channel 212 and the plate-shaped body. This second water passage can be equipped with a flow switch to control the flow of water. Specifically, the outlet of the water channel 212 can be in the form of a water pipe connector for connecting a water outlet pipe.

[0127] In this embodiment, the exhaust port 413 of the first housing 40 is located on the top wall 403 of the first housing 40. When the exhaust port 413 is located on the top wall 403 of the first housing 40, the exhaust port 413 can be efficiently and conveniently connected to the air supply module 5 located above the ceiling 6 through the shortest connection channel.

[0128] Specifically, the exhaust port 413 can be rectangular or quasi-rectangular, with its length direction perpendicular to the transverse direction (i.e., the length direction) of the first housing 40. The exhaust port 413 can be symmetrically arranged about the depth Z direction (i.e., the thickness direction) of the first housing 40, which helps to ensure the uniformity of the air outlet 413 of the first housing 40.

[0129] The air flowing in from the air inlet needs to be regulated in temperature and / or humidity and / or cleanliness by flowing laterally through the components inside the first housing 40 before being discharged from the air outlet 413. Devices for regulating the temperature and / or humidity and / or cleanliness of the air can be arranged sequentially along the lateral side of the first housing 40. The air outlet 413 and the air inlet can be located on opposite sides. The air outlet 413 can be located on the top wall 403 near the first side wall of the first housing 40. Figure 3 or Figure 4 The right sidewall 406 shown in the diagram, the air inlet can be close to the second sidewall of the first housing 40 ( Figure 3 or Figure 4 The left side wall 405 shown in the diagram allows air entering from the air inlet to flow sufficiently through the temperature and / or humidity and / or cleanliness processing components within the first housing 40.

[0130] The air inlet may include a fresh air inlet 411 connected to the outside and a return air inlet 412 connected to the inside. When the fan 23 is started, a negative pressure can be formed inside the first housing 40 of the indoor air handling unit 200, which introduces outdoor air into the first housing 40 through the fresh air inlet 411 and indoor air into the first housing 40 through the return air inlet 412, and the two mix inside the first housing 40.

[0131] Generally, there is a certain difference between the outdoor fresh air and the indoor air temperature / humidity. When the outdoor fresh air is directly introduced into the indoor, it will affect the indoor temperature / humidity, and will reduce or increase the temperature / humidity, so that it deviates from the preset target temperature / humidity. In the embodiment, the return air is introduced into the indoor through the return air inlet 412. Compared with the case of introducing fresh air completely from the outdoor, since the return air with the same temperature and humidity as the indoor is introduced to replace part of the fresh air, the cold or heat of the indoor return air can be effectively utilized, the fluctuation of the indoor temperature / humidity caused by the total air introduced can be reduced, and the load required for the indoor air handling device 200 to adjust the temperature / humidity can be reduced, thereby saving energy consumption.

[0132] The fresh air inlet 411 can be located on the top wall 403 of the first shell 40. For the fresh air inlet 411, it needs to be connected with the external air through a pipeline. When the fresh air inlet 411 is arranged on the top wall 403, a bent pipe structure can be arranged in a hidden manner by using the space above the ceiling 6. After the pipeline passes through the wall of the balcony 600, it is connected with the external air.

[0133] Further, the fresh air inlet 411 can be arranged close to the rear side wall 402 of the first shell 40. When the fresh air inlet 411 is arranged close to the rear side wall 402 of the first shell 40, the fresh air inlet 411 and the wall can be connected through an air inlet pipe with small bending and short length, so that it can be ensured that the external fresh air can be supplied into the first shell 40 from the fresh air inlet 411 with low resistance and large flow. In addition, when the fresh air inlet 411 is arranged close to the rear side wall 402, interference with other pipelines on the top can be avoided, and the pipelines above the top wall 403 of the first shell 40 can be arranged in the most simple manner.

[0134] In the embodiment, the opening position of the first shell 40 for penetrating the water pipe and the refrigerant pipe can be located between the air outlet 413 and the fresh air inlet 411, and specifically can be located in the middle of the top wall 403, and can be arranged corresponding to the positions of the first heat exchanger 21 and the second heat exchanger 22 in the first shell 40. In this way, the length of the water pipe and the refrigerant pipe connecting the first heat exchanger 21 to the top wall 403 in the first shell 40 can be reduced, the length of the refrigerant pipe connecting the second heat exchanger 22 to the top wall 403 in the first shell 40 can be reduced, the pipelines in the first shell 40 can be arranged compactly and occupy less space, and the miniaturization design of the first shell 40 can be ensured.

[0135] The return air inlet 412 is located on the side wall or the bottom wall 404 of the first shell 40.

[0136] In the embodiment, the return air inlet 412 can be located on the side wall of the first shell 40, or on the bottom wall 404 of the first shell 40. The return air inlet 412 belongs to a part of the air inlet, which is also arranged away from the exhaust air outlet 413. The exhaust air outlet 413 can be arranged on the top wall 403 and close to the first side wall of the first shell 40, and when the fresh air inlet 411 can be arranged on the top wall 403 of the first shell 40 and close to the second side wall of the first shell 40, the return air inlet 412 can be arranged on the second side wall or close to the bottom wall 404 of the second side wall.

[0137] In the embodiment, the fan 23 can include a fresh air fan 41 and a supply air fan 51. When the fresh air fan 41 is started, it can simultaneously generate negative pressure close to the arranged fresh air inlet 411 and return air inlet 412, so as to suck external air and indoor air into the first shell 40. That is to say, when the fresh air inlet 411 is arranged on the top wall 403, and the return air inlet 412 is arranged on the side wall or the bottom wall 404 close to the fresh air inlet 411, the same fresh air fan 41 can be used to realize the suction of the two kinds of air.

[0138] As shown in the embodiment, the distance W1 from the wall of the front side wall 401 of the first shell 40 is 550-600 mm; and the distance H1 from the ground of the bottom wall 404 of the first shell 40 is 1.7-1.8 m. Figure 2

[0139] In the embodiment, the first shell 40 has opposite front and rear side walls 401 and 402, and opposite top and bottom walls 403 and 404, and opposite left and right side walls 405 and 406. When the air treatment module 4 is installed close to the wall, the distance W1 from the wall of the front side wall 401 of the first shell 40 is 500-600 mm, so that the air treatment module 4 can be installed in a standard size (usually the depth Z is 600 mm) cabinet (such as a hanging cabinet), to realize hidden installation, which can realize installation and achieve an aesthetic effect. The hanging cabinet is located below the suspended ceiling 6 and close to the suspended ceiling 6. The distance from the top of the wall to the suspended ceiling 6 is 300 mm. When the air treatment module 4 is installed on a flat balcony 600, the distance H1 from the ground of the bottom wall 404 of the first shell 40 can be controlled to be 1.7-1.8 m. The above-mentioned distance H1 from the ground can on the one hand leave a distance below the first shell 40 for installation of a table basin, a washing machine, etc., and on the other hand can facilitate the user to operate below the first shell 40 without interference with the first shell 40, and in addition, the above-mentioned height distance is convenient for the user to open the hanging cabinet to maintain or replace the filter element of the air treatment module 4.

[0140] ​It should be noted that the ground clearance H1 of the bottom wall 404 of the first shell 40 can be personalized between 1.7 meters and 1.8 meters according to the user's needs. For example, for a user with a higher height, the ground clearance H1 of the bottom wall 404 of the first shell 40 can be set higher; for a user with a lower height, the ground clearance H1 of the bottom wall 404 of the first shell 40 can be set lower.

[0141] In one embodiment, the air treatment module 4 further comprises an air purification unit 43, the air purification unit 43, the second heat exchanger 22 and the first heat exchanger 21 are arranged transversely in the first shell 40; the front side wall 401 of the first shell 40 is detachable or openable to take out the air purification unit 43.

[0142] In the present embodiment, the air treatment module 4 can further comprise an air purification unit 43, which has slightly different functions and forms according to the different positions of the air purification unit 43.

[0143] For example, the air purification unit 43 can include a first filter element arranged between the air inlet and the second heat exchanger 22. In the flow direction of the air, the air purification unit 43 can be arranged downstream of the air inlet and upstream of the second heat exchanger 22. The air purification unit 43 is used to purify the air flowing into the air inlet. When the air inlet includes a fresh air inlet 411 and a return air inlet 412, the first filter element can include a fresh air filter element arranged downstream of the fresh air inlet 411 and a medium efficiency filter element arranged downstream of the return air inlet 412. It should be noted that the medium efficiency filter element can be arranged downstream of the return air inlet 412, for example, when the return air inlet 412 is arranged on the second side wall of the first shell 40, the medium efficiency filter element can be arranged on the second side wall, which can be arranged inside the first shell 40 or outside the first shell 40. When the medium efficiency filter element is arranged inside the first shell 40, the first shell 40 can be used to protect the medium efficiency filter element, and at the same time, the maximum transverse dimension of the whole machine treatment module can be reduced.

[0144] Alternatively, the air purification unit 43 can include a second filter element arranged between the second heat exchanger 22 and the air outlet 502. Specifically, in the air flow direction, the air purification unit 43 can be arranged downstream of the second heat exchanger 22 and upstream of the air outlet 413. The air purification unit 43 is configured to purify the air after heat exchange by the second heat exchanger 22 and then discharge the air through the air outlet 413. Specifically, the second filter element can be a high-efficiency filter element. Since the air outlet 413 is arranged on the top wall 403 of the first housing 40, the overall air flow path in the first housing 40 is along the lateral direction. In order to uniformly guide the air flowing in the lateral direction to the air outlet 413 of the top wall 403, the high-efficiency filter element can be arranged at an angle and its projection towards the air outlet 413 can cover the air outlet 413 to ensure that the air flowing out of the air outlet 413 is filtered by the high-efficiency filter element.

[0145] Alternatively, the air purification unit 43 includes a first filter element arranged between the air inlet and the second heat exchanger 22, and a second filter element arranged between the second heat exchanger 22 and the air outlet 502. Specifically, the specific arrangement and form of the first filter element and the second filter element can be referred to the specific description above, which will not be repeated here. It should be noted that the specific form of the first filter element and the second filter element in the embodiments of the present application is only for illustration, and those skilled in the art can make other changes under the technical essence of the present application, as long as the functions and effects achieved are the same or similar to the present application, which should be covered by the protection scope of the present application.

[0146] In the embodiments, the first heat exchanger 21 and the second heat exchanger 22 are arranged in the lateral direction of the first housing 40, i.e., the first heat exchanger 21 and the second heat exchanger 22 are arranged along the lateral dimension of the air treatment module 4. In addition, the air purification unit 43 can also be arranged in the lateral direction of the first housing 40. Taking the air purification unit 43 as a filter element with a predetermined thickness as an example, the thickness direction of the filter element is arranged along the lateral dimension of the air treatment module 4. Such arrangement is beneficial to maximize the use of the lateral dimension of the air treatment module 4 to arrange the core components in the first housing 40 of the air treatment module 4. In addition, the lateral dimension of the air treatment module 4 can be effectively controlled to be not too large, which improves the adaptability of the air treatment module 4. Specifically, the lateral dimension of the air treatment module 4 (i.e., the length dimension of the first housing 40) can be controlled to be within 900 mm or even smaller, so that it can be adapted to the depth dimension of all balconies 600.

[0147] In addition, the air purification unit 43 is a relatively consumable part, and needs to be replaced periodically after being used for a predetermined length of time. When the air purification unit 43 is arranged in the first shell 40 in the thickness direction, the air purification unit 43 can be replaced by plugging and unplugging.

[0148] The front side wall 401 of the first shell 40 is detachable or openable, and is used to take out the air purification unit 43. When the front side wall 401 of the first shell 40 is detachable or openable, the air purification unit 43 can be conveniently replaced.

[0149] In an embodiment, the air inlet includes a fresh air inlet 411 and a return air inlet 412, and the air inlet, the second heat exchanger 22, the first heat exchanger 21, and the air purification unit 43 are arranged in sequence in the direction of air flow.

[0150] In the embodiment, the air inlet can include a fresh air inlet 411 connected to the outside and a return air inlet 412 connected to the inside. External air can flow into the first shell 40 through the fresh air inlet 411, and indoor air can flow into the first shell 40 through the return air inlet 412. After the external air and the indoor air flow into the first shell 40, they need to be mixed and then exchanged with the second heat exchanger 22. After being exchanged with the second heat exchanger 22, the air is purified by the air purification unit 43 and then discharged from the first shell 40 through the air outlet 413. Therefore, the air inlet, the second heat exchanger 22, and the air purification unit 43 are arranged in sequence along the air flow channel 222.

[0151] The first heat exchanger 21 is generally provided with a temperature detection part for detecting the water temperature on the water flow channel 212. If the first heat exchanger 21 is located downstream of the second heat exchanger 22, in the case of refrigeration, when the temperature detected by the temperature detection part is low when the cold air flowing through the second heat exchanger 22 flows through the first heat exchanger 21, the freeze protection mechanism of the first heat exchanger 21 can be triggered, which can cause the corresponding components to malfunction, thereby increasing energy consumption, and can also cause the service life of the components to be reduced.

[0152] Furthermore, regarding the first heat exchanger 21 and the second heat exchanger 22 within the first housing 40, both are equipped with refrigerant flow channels. For example, during cooling, the air flowing in from the air inlet is at a relatively high temperature, and condensation may occur on the surfaces of the first heat exchanger 21 and the second heat exchanger 22 as it flows through them. The air purification unit 43 itself is a component that is not prone to condensation. When the air inlet, the first heat exchanger 21, the second heat exchanger 22, and the air purification unit 43 are arranged sequentially along the airflow direction, it is equivalent to separating the components prone to condensation from the air purification unit 43. This facilitates centralized treatment of condensation generated by these components. For example, a water collection tray for collecting condensate can be provided at the bottom of the first heat exchanger 21 and the second heat exchanger 22. Furthermore, achieving dry and wet separation helps ensure a longer service life for the air purification unit 43.

[0153] In one embodiment, the second heat exchanger 22 is vertically disposed close to or adjacent to the rear sidewall 402 of the first housing 40.

[0154] In this embodiment, when the first heat exchanger 21 is vertically arranged close to or adjacent to the rear sidewall 402 or front sidewall 401 of the first housing 40, along the transverse direction ( Figure 2 As shown in the horizontal direction X, a space can be left open to facilitate the full mixing of indoor air flowing in from the air inlet (specifically, the external space flowing in from the fresh air inlet 411 and the indoor air flowing in from the return air inlet 412). This not only makes the temperature of the mixed air more uniform, but also makes the flow field of the mixed air more stable. When it passes through the second heat exchanger 22, it can perform heat exchange more fully and improve the heat exchange efficiency.

[0155] Furthermore, when the first heat exchanger 21 is vertically positioned close to or adjacent to the rear sidewall 402 or front sidewall 401 of the first housing 40, it effectively ensures that at least the space in the middle of the second heat exchanger 22 is left unoccupied, and the heat exchange efficiency in the middle of the second heat exchanger 22 is the highest. In this case, the mixed air can flow along the flow channel in the middle of the second heat exchanger 22 to the second heat exchanger 22, achieving sufficient contact and heat exchange with the middle region of the second heat exchanger 22, thereby achieving a high heat exchange efficiency.

[0156] The air treatment module 4 can further comprise a controller, which can be in the form of an electric control board or an electric control box 46. When the first heat exchanger 21 is arranged vertically close to the rear side wall 402 of the first housing 40, the controller can be arranged vertically close to the front side wall 401 of the first housing 40; when the first heat exchanger 21 is arranged vertically close to the front side wall 401 of the first housing 40, the controller can be arranged vertically close to the rear side wall 402 of the first housing 40. In this way, the flow passage in the middle of the second heat exchanger 22 can be ensured to be unobstructed, and further, the controller is arranged upstream of the second heat exchanger 22, and can be cooled by the flow of air.

[0157] Please refer to Figure 4 , Figure 5 and Figure 6 In an embodiment, the air treatment module 4 further comprises a wet membrane humidifier 65 arranged in the first housing 40, the wet membrane humidifier 65 is connected with a clean water inflow pipe 63, clean water can flow into the wet membrane humidifier 65 through the clean water inflow pipe 63, the clean water inflow pipe 63 penetrates the top wall 403 of the first housing 40, and the clean water inflow pipe 63 is further provided with an electromagnetic valve 64, which is used to control the opening and closing of the clean water inflow pipe 63.

[0158] In the embodiment, the air treatment module 4 can further be provided with a humidity adjusting mechanism, which can be used to humidify the air flowing into the room. In particular, when the indoor air treatment system is running in the heating mode, the humidity adjusting mechanism for adjusting humidity can be arranged on the second heat exchanger 22 or downstream of the second heat exchanger 22, and when the mixed gas composed of the outdoor introduced air and the indoor return air flows through the second heat exchanger 22, it can be in contact with the humidity adjusting mechanism, thereby increasing the humidity of the air sent into the room, and achieving the purpose of adjusting the indoor humidity.

[0159] The principle of adjusting humidity by the humidity adjusting mechanism can be different according to the form of the humidity adjusting mechanism. For example, the humidity adjusting mechanism can be in the form of a wet membrane humidifier 65 arranged upstream of the second heat exchanger 22. When the humidity adjusting mechanism is a wet membrane humidifier 65, the wet membrane humidifier is connected with a clean water inflow pipe 63, and clean water can flow into the wet membrane humidifier 65 through the clean water inflow pipe 63 to provide the wet membrane humidifier 65 with clean water required for humidification.

[0160] Specifically, the clean water inflow pipeline 63 can be arranged on the top wall 403 of the first shell 40, close to the installation positions of the refrigerant pipeline and the water pipeline on the top wall 403. On the one hand, the installation volume required by the indoor air treatment system can be reduced as much as possible. On the other hand, when multiple pipelines are arranged in a concentrated manner, the operator can conveniently perform centralized installation and maintenance operations at the same position.

[0161] The electromagnetic valve arranged on the clean water inflow pipeline 63 is used to control the on-off of the clean water inflow pipeline. The length of time for which the electromagnetic valve is turned on or off can be controlled to control the length of time for which the wet membrane humidifier 65 supplies clean water, so as to regulate the humidity parameter of the wet membrane humidifier 65. Of course, the regulation of the humidity parameter of the wet membrane humidifier 65 is not limited to the above examples. For example, the wet membrane humidifier 65 can also be regulated in multiple regulation directions such as the amount of clean water sprayed on the wet membrane of the wet membrane humidifier 65, so as to achieve the regulation of humidity.

[0162] In an embodiment, the air inlet includes a fresh air inlet 411 and a return air inlet 412. In the direction of air flow, the air inlet, the first heat exchanger 21, the second heat exchanger 22, the wet membrane humidifier 65, and the air purification unit 43 are arranged in sequence.

[0163] In the above embodiment, in the direction of air flow, the air inlet, the first heat exchanger 21, the second heat exchanger 22, and the air purification unit 43 are arranged in sequence. In this embodiment, the wet membrane humidifier 65 is taken as an example for supplementary description.

[0164] In this embodiment, for the embodiment in which the wet membrane humidifier 65 is arranged, in the direction of air flow, the wet membrane humidifier 65 can be located downstream of the second heat exchanger 22 and upstream of the air purification unit 43. In this way, the wet membrane humidifier 65 can be used to humidify the air treated by the second heat exchanger 22. In addition, since the wet membrane humidifier 65 can produce water droplets downward during use, the wet membrane humidifier 65 and the component that is prone to produce refrigerant water can be arranged close to each other, so as to facilitate the drainage treatment of the wet membrane humidifier 65 and the component that is prone to produce refrigerant water.

[0165] In an embodiment, the air treatment module 4 can further include a first water collecting tray 66 located below the first heat exchanger 21 and the second heat exchanger 22, used to collect the condensed water of the first heat exchanger 21 and the second heat exchanger 22.

[0166] Alternatively, the air treatment module 4 further comprises a first water receiving tray 66 and a wet membrane humidifier 65, the first water receiving tray 66 is located below the first heat exchanger 21, the second heat exchanger 22 and the wet membrane humidifier 65, and is used to receive the condensed water of the first heat exchanger 21, the second heat exchanger 22 and the wet membrane humidifier 65.

[0167] In the embodiment, for the components prone to produce condensed water, by arranging the first water receiving tray 66 directly below the components prone to produce condensed water, the condensed water is collected and then discharged. For example, when the components prone to produce condensed water include the first heat exchanger 21 and the second heat exchanger 22, the first water receiving tray 66 is located directly below the first heat exchanger 21 and the second heat exchanger 22; when the components prone to produce condensed water include the first heat exchanger 21, the second heat exchanger 22 and the wet membrane humidifier 65, the first water receiving tray 66 is located directly below the first heat exchanger 21, the second heat exchanger 22 and the wet membrane humidifier 65.

[0168] Further, the air treatment module 4 can further comprise a second water receiving tray 67, the second water receiving tray 67 is located below the first water receiving tray 66 and the downward projection of the first water receiving tray 66 falls entirely within the second water receiving tray 67, the first water receiving tray 66 has a first drain pipe, the second water receiving tray 67 has a second drain pipe, the first drain pipe is inserted into the second drain pipe and is spaced apart from the outer wall of the first drain pipe and the inner wall of the second drain pipe.

[0169] In the embodiment, the air treatment module 4 can further comprise a second water receiving tray 67, which is used to receive a small amount of condensed water that may be produced by other components, and timely discharge the condensed water to prevent its accumulation in the first housing 40 and breeding of bacteria, etc.

[0170] The second water receiving tray 67 is located directly below the first water receiving tray 66, and specifically, the second water receiving tray 67 can be installed on the bottom wall 404 of the first housing 40. The surface area of the second water receiving tray 67 can be the same as or similar to the surface area of the bottom wall 404.

[0171] The first water receiving tray 66 is provided with a first drain pipe, and the second water receiving tray 67 is provided with a second drain pipe, the upper first drain pipe can be inserted into the lower second drain pipe and is spaced apart from the inner wall of the second drain pipe, leaving a flow gap for discharging the condensed water on the second water receiving tray.

[0172] When the first drain pipe and the second drain pipe are installed inside and outside each other, the pipe layout can be simplified and the number of openings on the first housing 40 can be reduced, making the structure inside the first housing 40 more compact. In addition, since the downward projection of the first water receiving tray 66 falls completely into the second water receiving tray 67, even if the first drain pipe of the first water receiving tray 66 is blocked or other problems occur, and the condensate accumulated in the first water receiving tray 66 overflows, it can flow into the second water receiving tray 67 under the action of gravity, thereby using the second water receiving tray 67 for drainage, ensuring the reliability of drainage.

[0173] like Figure 7 As shown, in one embodiment, the air supply module 5 includes a fan box and an air supply fan 51, the air supply fan 51 being disposed within the fan box, and the impeller of the air supply fan 51 rotating along the longitudinal direction (i.e., Figure 2 The height shown extends in the Y direction.

[0174] In this embodiment, the air supply module 5 may include a fan housing and an air supply fan 51 disposed within the fan housing. To achieve better noise reduction, the air supply module 5, which has a second housing 50, can be installed completely above the ceiling 6. To install the air supply module 5 on the ceiling 6, which has a limited height, the air supply fan 51 is installed horizontally.

[0175] Specifically, for the air supply fan 51, the thickness of its impeller is relatively small compared to its outer perimeter. To minimize the size required by the air supply module 5 in the height direction Y, the rotation axis of the impeller of the air supply fan 51 extends along the longitudinal direction. Of course, in this embodiment, it is not excluded that the rotation axis of the impeller of the air supply fan 51 forms a certain angle with the longitudinal direction. In principle, any embodiment that ensures the second housing 50 of the air supply module 5 can be installed above the ceiling 6 can be applied to this embodiment. When the rotation axis of the impeller of the air supply fan 51 extends entirely along the longitudinal direction, the size required by the air supply module 5 in the height direction Y is minimized.

[0176] In one embodiment, the blower 51 includes a first volute 511, a first impeller disposed within the first volute 511, a second volute 512, and a second impeller disposed within the second volute 512. The rotation axes of the first impeller and the second impeller are offset and both extend in the longitudinal direction. At least a portion of the front part of the surrounding plate 513 of the first volute 511 and at least a portion of the rear part of the surrounding plate 513 of the second volute 512 are the same plate, or at least a portion of the front part of the surrounding plate 513 of the first volute 511 and at least a portion of the rear part of the surrounding plate 513 of the second volute 512 are different plates that are close to each other.

[0177] For the ceiling 6 used in the balcony 600, the height of the ceiling 6 is usually less than 350 mm, and it is difficult for the existing large fan to be completely installed above the ceiling 6. In a specific scenario, when a clothes hanger or the like needs to be installed below the ceiling 6, the height of the ceiling 6 usually needs to be further reduced, usually controlled within 250 mm. Thus, it is more difficult for the existing large fan to be completely installed above the ceiling 6.

[0178] In the embodiment, the air supply fan 51 can be composed of two small-size fans. Compared with one large-size fan, the two small-size fans can reduce the installation size for installing the air supply fan 51, so that the size of the second shell 50 for installing the air supply fan 51 is as small as possible, thereby being completely installed above the ceiling 6. In addition, compared with one large-size fan, the two small-size fans can also reduce the noise generated when the fan works. Specifically, when the large-size fan and the two small-size fans work at the same rotating speed, the noise generated by the large-size fan is at least more than 3 decibels.

[0179] In the specific installation, in order to reduce the space size as much as possible, the rotating shafts of the two fans 23 extend along the longitudinal direction, and further, the first impeller rotating shaft of one fan 23 and the second impeller rotating shaft of the other fan 23 can be staggered.

[0180] Specifically, the front part of the at least part of the first volute 511 of the surrounding plate 513 and the rear part of the at least part of the second volute 512 of the surrounding plate 513 are the same plate, and the surrounding plates 513 adjacent to the two volutes can be shared, thereby being beneficial to reducing the volume. In addition, the front part of the at least part of the first volute 511 of the surrounding plate 513 and the rear part of the at least part of the second volute 512 of the surrounding plate 513 are different plates close to each other. The gap between the two surrounding plates 513 close to each other can be 0 or a small size. Specifically, the value of the gap can be different according to the specific mechanism of the fan 23, such as the radius of the surrounding plate 513, and the present application does not limit the value.

[0181] In an embodiment, the fan box is laid above the ceiling 6, two adjacent sides of the fan box are respectively provided with a first air inlet 501, and the fan box further comprises a blocking plate. When one first air inlet 501 is communicated with the air outlet 413 through the pipeline, the blocking plate is used to block the other first air inlet 501.

[0182] In the embodiment, the fan box has a box structure as a whole, and has opposite length, width and thickness dimensions. The thickness dimension can be the smallest dimension. The fan box can be placed horizontally above the ceiling 6, and the thickness dimension of the fan box extends along the height direction Y. The fan box has opposite top and bottom surfaces, and opposite front and rear side surfaces, and opposite left and right side surfaces. For example, the right side surface of the fan box is provided with the air outlet 502, and the bottom and front side surfaces of the fan box are respectively provided with the first air inlets 501. During installation, one of the first air inlets 501 can be connected to the air outlet 413 through a pipeline according to the current installation condition, and the other first air inlet 501 is blocked by a blocking plate, so as to improve the adaptability of the fan box installation.

[0183] As shown in the drawings, Figure 7 In one embodiment, a cavity 514 is arranged between the air supply outlet 515 of the air supply fan 51 and the air outlet 502 of the second shell 50. The cavity 514 is a hollow cavity with a certain flow cross-sectional dimension. Specifically, the cavity 514 can be formed by part of the second shell 50 and a partition plate 516 arranged at the air supply outlet 515. For example, the cavity 514 can be a regular cuboid chamber as a whole, and the air supply outlet 515 is arranged opposite to the air outlet 502. Of course, the specific structure of the cavity 514 is not limited to the above example, and those skilled in the art can also make adaptive adjustments according to actual needs.

[0184] The air discharged from the air supply outlet 515 of the air supply fan 51 first passes through the cavity 514, is subjected to noise reduction treatment, and then is discharged through the air outlet 502 of the second shell 50, so as to ensure that the user has a better silent effect. The flow cross-sectional dimension of the cavity 514 is greater than the flow area of the air supply outlet 515. When the airflow flows from the air supply outlet 515 with a smaller flow area into the cavity 514 with a larger flow cross-sectional dimension, the cavity 514 can reduce the aerodynamic noise of the airflow flowing out of the air supply outlet 515, so that the flow of the gas is smoother, thereby achieving the purpose of noise reduction.

[0185] In one embodiment, the air treatment module 4 can further include a heating unit 45.

[0186] In the flow direction of the air, the heating unit 45 is arranged downstream of the air purification unit 43 (for example, a high-efficiency filter element). The heating unit 45 is used to heat and warm the air flowing out of the air purification unit 43, so as to reduce the humidity in the air. Specifically, the heating unit 45 can be in the form of an electric heating element, for example, a PTC heating rod. The electric heating element can include a plurality of electric heating elements, and the plurality of electric heating elements are arranged at intervals in the cross section of the air outlet 413, so as to uniformly heat the air.

[0187] In a specific application scenario, for example, in the plum rain season, the user has a large demand for dehumidification, but has a small demand for temperature regulation. In this case, the heating unit 45 is started to dehumidify the air introduced through the air inlet. Of course, in the above scenario, the compressor 1 of the outdoor unit 100 can also be started in a low-power mode to dehumidify the air through refrigeration, and the heating unit 45 can be used to heat the dehumidified air. The combination of dehumidification through refrigeration and heating through the heating unit 45 can achieve efficient dehumidification.

[0188] In an embodiment, the air inlet includes a fresh air inlet 411 and a return air inlet 412. The fresh air inlet 411 is configured to communicate with the outdoor environment to introduce outdoor air, and the return air inlet 412 is configured to communicate with the indoor environment to introduce indoor air into the indoor air treatment device 200. The fresh air inlet 411 and the return air inlet 412 can be in a simultaneously open state to mix the outdoor air and the indoor air in the indoor air treatment device 200.

[0189] In this embodiment, the air inlet can include a fresh air inlet 411 that communicates with the outdoor environment and a return air inlet 412 that communicates with the indoor environment. The indoor air treatment device 200 can include a first housing 40. When the fan 23 is started, a negative pressure can be formed inside the first housing 40 of the indoor air treatment device 200, and outdoor air can be introduced into the first housing 40 through the fresh air inlet 411, and indoor air can be introduced into the first housing 40 through the return air inlet 412. The two are mixed in the first housing 40, and the mixed gas is subsequently exchanged with the second heat exchanger 22, and then flows out of the air outlet 502 and into the indoor environment through the indoor air delivery end 31.

[0190] Generally, there is a certain difference in temperature / humidity between outdoor fresh air and indoor air. When outdoor fresh air is directly introduced into the indoor environment, it will affect the temperature / humidity of the indoor environment, and will lower or raise the temperature / humidity, causing it to deviate from the preset target temperature / humidity. In this embodiment, the return air is introduced into the indoor environment through the return air inlet 412. Compared to the case where fresh air is completely introduced from the outdoor environment, since the return air with the same temperature and humidity as the indoor environment is introduced to replace part of the fresh air, the cold or heat of the return air can be effectively utilized, the fluctuation of the indoor temperature / humidity caused by the total air introduced can be reduced, and the load required for temperature / humidity adjustment by the indoor air treatment device 200 can be reduced, thereby saving energy consumption.

[0191] In an embodiment, the fan 23 includes a fresh air fan 41 and a supply air fan 51. The fresh air fan 41 and the supply air fan 51 can be in a simultaneously open state. The fresh air fan 41 is configured to introduce the outdoor air into the indoor air treatment device 200, and the supply air fan 51 is configured to supply the mixed outdoor air and indoor air into the indoor air output end.

[0192] In the present embodiment, the fan 23 can include a fresh air fan 41 for introducing outdoor air into the indoor air handling device 200, and a supply fan 51 for sending the mixed and heat-exchanged outdoor air and indoor air to the indoor air delivery terminal 31.

[0193] In use, the fresh air fan 41 and the supply fan 51 can be turned on at the same time, and the two work together to suck outdoor air and / or indoor return air into the first housing 40 of the indoor air handling device 200 for mixing, and the mixed air is then sent out from the air outlet 502 after heat exchange with the second heat exchanger 22, and flows into the indoor space through the indoor air delivery terminal 31.

[0194] In one embodiment, the fresh air inlet 411 and / or the return air inlet 412 is provided with a flow regulating device for regulating the mixing ratio of the outdoor air and the indoor air.

[0195] Further, the fresh air inlet 411 and / or the return air inlet 412 is provided with a flow regulating device for regulating the mixing ratio of the outdoor air and the indoor air.

[0196] In the present embodiment, at least one of the fresh air inlet 411 and the return air inlet 412 can be provided with a flow regulating device, which can be a flow valve with adjustable opening degree, etc. By adjusting the flow regulating device, the mixing ratio of the outdoor air and the indoor air can be controlled, i.e. the ratio between the fresh air introduced from the outdoor and the return air introduced from the indoor in the total air introduced can be controlled.

[0197] Specifically, the flow regulating device can be electrically connected with a controller, and the controller is electrically connected with the air quality detection device 34. The controller can adjust the opening degree of the flow regulating device according to the temperature and / or humidity and / or cleanliness of the indoor air detected by the air quality detection device 34. In addition, the controller can also receive the air quality (including temperature and / or humidity and / or cleanliness) signal of the outdoor air, and the controller can determine the opening degree of the flow regulating device based on the air quality of the outdoor air and the air quality of the indoor air.

[0198] For example, when the outdoor temperature and humidity are close to the indoor temperature and humidity, and the outdoor air cleanliness is higher than the indoor air cleanliness, the proportion of the outdoor air flowing into the fresh air inlet 411 can be increased, and even all the air can be introduced through the fresh air inlet 411. When the outdoor temperature and humidity are quite different from the indoor temperature and humidity, and the outdoor air cleanliness is relatively poor, the proportion of the outdoor air flowing into the fresh air inlet 411 can be appropriately reduced.

[0199] For example, when the outdoor temperature and humidity are close to the indoor temperature and humidity, and the outdoor air cleanliness is higher than the indoor air cleanliness, the proportion of the outdoor air flowing into the fresh air inlet 411 can be increased, and even all the air can be introduced through the fresh air inlet 411. When the outdoor temperature and humidity are quite different from the indoor temperature and humidity, and the outdoor air cleanliness is relatively poor, the proportion of the outdoor air flowing into the fresh air inlet 411 can be appropriately reduced. Figure 1As shown, the indoor air treatment device 200 provided in the embodiments of the present application can be applied in an indoor air treatment system, which mainly comprises the indoor air treatment device 200 and the outdoor unit 100.

[0200] The outdoor unit 100 can comprise a compressor 1, a heat exchange unit, a throttling unit, a reversing valve and the like. The outdoor unit 100 has a refrigerant input port 11 and a refrigerant output port 12, which can be connected with the indoor air treatment device 200 through a refrigerant connecting pipe, and cooperate with the indoor air delivery end 31 and the indoor radiation end 32, so as to realize the function of indoor temperature and / or humidity and / or cleanliness adjustment.
