The preferred technical scheme of the cabinet air-conditioner indoor unit and the air conditioner is described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a cabinet air-conditioning indoor unit provided in an embodiment of the present application, fig. 2 is a schematic structural view of a humidifying component in the cabinet air-conditioning indoor unit provided in the embodiment of the present application, and fig. 3 is a schematic structural view of a refrigerating component in the cabinet air-conditioning indoor unit provided in the embodiment of the present application.
As shown in fig. 1 to 3, an embodiment of the present application provides a cabinet air conditioner indoor unit 100, which includes a casing assembly 110, an indoor heat exchanger 120, and a humidifying assembly 130, where the indoor heat exchanger 120 and the humidifying assembly 130 are both disposed in the casing assembly 110;
it can be understood that the indoor heat exchanger 120 is located inside the housing assembly 110 and is fixedly connected with the housing assembly 110, and a person skilled in the art can set a fixing manner between the indoor heat exchanger 120 and the housing assembly 110 according to actual needs. It will be readily appreciated that the indoor heat exchanger 120 serves to evaporate refrigerant at low pressure, absorb heat from the gas and thereby cool the gas.
The indoor heat exchanger 120 is used for exchanging heat with air flowing through the indoor heat exchanger 120, and the indoor heat exchanger 120, the compressor, the condenser, the throttling device, the connecting pipeline and other accessories jointly form a vapor compression refrigeration cycle system, so that refrigeration/heating of the cabinet air conditioner indoor unit 100 is realized, and specific principles and structures are not described herein again.
Generally, the indoor heat exchanger 120 here may be an evaporator. In addition, it is understood that the evaporator performs heat exchange with the incoming air, and the gas after the heat exchange flows into the room again.
In some examples, the housing assembly 110 includes a front panel and a back panel disposed opposite to each other, and two side panels disposed between and enclosing a cavity with the front panel and the back panel, and it is apparent that the cavity enclosed by the back panel, the front panel and the two side panels is a cylindrical cavity, or the cavity has two open ends. The housing assembly 110 further comprises a top plate at the top and a bottom plate at the bottom, the top plate and the bottom plate are arranged oppositely, the top plate and the bottom plate cover openings at two ends of the cylindrical cavity respectively, and the back plate, the front panel, the two side plates, the top plate and the bottom plate enclose the housing assembly 110 together.
Illustratively, the back plate, the front panel, the two side plates, the top plate and the bottom plate can be connected by a detachable connection mode or a fixed connection mode.
In practical applications, a fan is usually disposed in the cabinet air-conditioning indoor unit 100, for example, a cooling function of an air conditioner, the fan is used for sucking indoor air and discharging the air processed by the cabinet air-conditioning indoor unit 100 into the room, the evaporator is used for absorbing heat of the air entering the cabinet air-conditioning indoor unit 100, and the refrigerant is evaporated in a pipeline of the evaporator to cool the evaporator.
Illustratively, the indoor heat exchanger 120 is a three-stage fin heat exchanger covering the space in front of and above the fan.
The humidifying assembly 130 includes a water collecting tank 131 and a nozzle 132, which are communicated with each other, the water collecting tank 131 is communicated with a condensed water pipe of the indoor unit 100 of the cabinet air conditioner, and the nozzle 132 faces the indoor heat exchanger 120 to spray atomized liquid to the indoor heat exchanger 120.
It should be noted that, when the air conditioner is in the cooling mode, the low-temperature condensed liquid passes through the evaporator, and then exchanges heat with the external air, so as to achieve the cooling effect, and meanwhile, the moisture in the external air is condensed therewith, and further condensed water is formed.
It is understood that when the surface temperature of the indoor heat exchanger 120, i.e., the evaporator, is lower than the dew-point temperature of the air, condensed water is formed on the surface of the evaporator, which is generated by the cabinet air conditioner indoor unit 100 itself, and the condensed water flows into the water collecting tank 131 through the condensed water pipe to be stored.
In this embodiment, it can be understood that the design of the water collection tank 131 can play a role in collecting the condensed water, and the collected condensed water is sprayed on the indoor heat exchanger 120 through the nozzle 132 to increase the humidity of the surface of the indoor heat exchanger 120, thereby increasing the thickness of frost.
In some examples, the water collection tank 131 may be mounted at the bottom end of the housing assembly 110 using a detachable or fixed connection, for example, a bolt or snap connection.
For example, the water collecting tank 131 may be directly installed under the indoor heat exchanger 120 when in use, so as to collect all the condensed water generated by the indoor heat exchanger 120.
In addition, in the present embodiment, the nozzle 132 is used to atomize and spray the condensed water in the water collection tank 131 onto the surface of the indoor heat exchanger 120. When the water-cooling device is used, the condensed water in the water collecting tank 131 flows into the nozzle 132, and the nozzle 132 atomizes the water and sprays the atomized water onto the internal heat exchanger to form a water curtain to increase the humidity of the surface of the water curtain.
Alternatively, the nozzle 132 may be an atomizer, and the particular embodiments of the present application are not so limited.
In some examples, the water collecting tank 131 may have a regular shape such as a cylinder, a sphere, a prism, or other irregular shapes. The specific shape, the embodiments of the present application are not so limited.
Through the arrangement, namely, through the design of the humidifying assembly 130, the condensed water generated by the cabinet air conditioner indoor unit 100 can be utilized to spray the indoor heat exchanger 120, so that the surface humidity of the indoor heat exchanger is increased, the frosting thickness of the indoor heat exchanger 120 is improved, the self-cleaning capability of the cabinet air conditioner indoor unit 100 is improved, the cost is saved, and the user experience feeling is better.

The semiconductor refrigeration uses the peltier effect of semiconductor materials, that is, when direct current passes through a couple formed by series-connected semiconductor materials, the two ends of the couple can absorb heat and release heat respectively, thereby achieving the purpose of refrigeration.
On the basis, the plurality of semiconductor refrigerating pieces 141 are used for cooling and refrigerating the indoor heat exchanger 120, condensed frost is prevented from being dissolved by water mist of condensed water sprayed from the nozzles 132, the frosting capacity of the surface of the indoor heat exchanger 120 is improved, the frosting thickness is increased, and the self-cleaning capacity of the cabinet type air-conditioning indoor unit 100 is further improved.
In some examples, the plurality of semiconductor cooling members 141 are disposed on the surface of the indoor heat exchanger 120 at regular intervals, and of course, the plurality of semiconductor cooling members may also be disposed on the surface of the indoor heat exchanger 120 in a disc manner, and the embodiments of the present invention are not limited herein.
In other examples, the plurality of semiconductor cooling members 141 may be detachably or fixedly attached to the indoor heat exchanger 120, for example, by bolts or snap-fit connection. The specific connection form is not limited too much here.
As shown in fig. 1 to 3, in an alternative embodiment, the humidifying assembly 130 further includes a first pipe 133 and a second pipe 134, one end of the first pipe 133 is communicated with the water collecting tank 131, and the other end of the first pipe 133 is communicated with the nozzle 132.
It can be understood that the water collecting tank 131 and the nozzle 132 are communicated with each other through the first pipe 133, so that the condensed water in the water collecting tank 131 can flow into the nozzle 132.
Of course, the first pipe 133 is designed, on the one hand, for the circulation of the condensed water, and on the other hand, because of the space inside the housing assembly 110, the nozzle 132 thereof may face the indoor heat exchanger 120, and because the indoor heat exchanger 120 extends along the height direction of the housing assembly 110, a certain size of the first pipe 133 is required between the water collection tank 131 and the nozzle 132.
In some examples, the first pipe 133 may be detachably or fixedly coupled to the water collecting tank 131 at one end thereof, for example, by a bolt or a snap-fit.
Similarly, in some examples, the other end of the first pipe 133 and the nozzle 132 may be detachably or fixedly connected, such as by bolts or snaps.
Due to the design, the first pipeline 133 and the nozzle 132 can be mounted and dismounted, and can be dismounted and maintained at a later stage.
Wherein, one end of the second pipeline 134 is communicated with the water collecting tank 131, and the other end of the second pipeline 134 is communicated with the condensate pipe.
It can be understood that the water collecting tank 131 is communicated with the condensed water pipe through the second pipeline 134, so as to ensure that the condensed water in the condensed water pipe flows into the water collecting tank 131.
In addition, it should be understood that the design of the second pipeline 134 can be adjusted according to actual situations, so as to reduce the modification of the inside of the cabinet air-conditioning indoor unit 100 and reduce unnecessary processes.
In some examples, the second pipe 134 may be detachably or fixedly connected to the water collection tank 131 at one end thereof, for example, by bolts or a snap-fit connection.
Similarly, in some examples, the other end of the second pipe 134 may be detachably or fixedly connected to the condensate pipe, for example, by a bolt or a snap connection.
Due to the design, the second pipeline 134 can be mounted and dismounted, and further can be dismounted and maintained in the later period.
As shown in fig. 1 to 3, in an alternative embodiment, the second pipe 134 communicates with an upper wall of the water collecting tank 131;
and/or the first pipe 133 communicates with the bottom wall of the water collecting tank 131.
It can be understood that the embodiments of the present application can have three cases, which are respectively: the second pipe 134 communicates with the upper wall of the sump 131; alternatively, the first pipe 133 is communicated with the bottom wall of the water collecting tank 131; alternatively, the second pipe 134 communicates with the upper wall of the water collecting tank 131, and the first pipe 133 communicates with the bottom wall of the water collecting tank 131.
In addition, it should be understood that such a design may facilitate the flow of the water collection tank 131 into the nozzle 132 while reducing the cost of the first and second pipes 133 and 134.
As shown in fig. 1 to 3, in an alternative embodiment, the humidifying assembly 130 further includes a driving pump 135, and the driving pump 135 is disposed on the first pipe 133 to drive the condensed water in the first pipe 133 to flow to the nozzle 132.
It will be appreciated that the pump 135 may be actuated to provide motive force for the flow of condensate in the first conduit 133 to the nozzle 132.
So configured, water with certain pressure can be provided to the nozzle 132, and the atomization effect of the nozzle 132 is improved.
As shown in fig. 1 to 3, in an alternative embodiment, the humidifying assembly 130 further includes a solenoid valve 136 and a first controller, the solenoid valve 136 is disposed on the second pipeline 134, and the first controller is electrically connected to the solenoid valve 136.
It can be understood that the solenoid valve 136 is used for controlling the conducting state of the second pipeline 134, when it is required to open, the condensed water in the condensed water pipe flows into the water collecting tank 131 through the second pipeline 134; when the condensed water is not required to flow into the water collection tank 131, the condensed water is prevented from flowing into the water collection tank 131 by closing the second pipe 134.
It should be noted that, when the cabinet air-conditioning indoor unit 100 is in the self-cleaning state, the electromagnetic valve 136 is in the closed state, that is, no condensed water needs to flow into the water collecting tank 131, because there is dirt and then wastewater is generated during self-cleaning, and the wastewater does not need to flow into the water collecting tank 131 to block the nozzle 132 and be damaged.
In addition, in the embodiment of the present application, when the cabinet air-conditioning indoor unit 100 is not in the self-cleaning state, the humidifying component 130 and the cooling component 140 are in operation, and when the cabinet air-conditioning indoor unit 100 is in the self-cleaning state, the humidifying component 130 and the cooling component 140 are in suspension of operation.
Specifically, the first controller may control to execute a corresponding function according to a function instruction input by a user, for example, the user may select a required function by operating a remote controller of the cabinet air conditioner indoor unit 100, may also send a remote instruction by an application installed on a terminal device, and may also input the function instruction by using voice, where a manner of inputting the function instruction by the user is not particularly limited in this embodiment.
Taking the example that the user inputs a function command through the remote controller, the user can select the humidification function through the remote controller, and the first controller controls the open/close state of the electromagnetic valve 136 after receiving the command of the humidification function.
As shown in fig. 1 to 3, in an alternative embodiment, the humidifying assembly 130 further includes an overflow pipe 137, and the overflow pipe 137 is communicated with the second pipe 134.
It will be appreciated that the overflow pipe 137 is designed to flow out through the overflow pipe 137 when the condensed water collected in the sump 131 is overfilled.
In some examples, the overflow pipe 137 may be connected to the upper sidewall of the water collecting tank 131 or may communicate with the second pipe 134, particularly, as long as the purpose can be achieved, and the embodiment of the present invention is not limited thereto.
As shown in fig. 1 to 3, in an alternative embodiment, the humidifying assembly 130 further includes a filter disposed on the first pipe 133 between the water collecting tank 131 and the driving pump 135.
It will be appreciated that the filter is designed to filter out impurities in the condensate in the tank, to avoid damage to the drive pump 135, and to further increase the service life of the drive pump 135.
In order to further improve the service life of the humidification unit 130, the purity of the condensed water may be controlled by a filter, so that the condensed water is not easily corroded and has a longer service life.
In this embodiment, the filter is a loose and porous material, for example, the filter may mainly be made of sponge, woven fabric, asbestos, or the like, and of course, the filter may also be made of a plurality of metal meshes arranged in a stacked manner, so as to intercept impurities carried in condensed water when the condensed water passes through the filter.
In some examples, the cross-section of the filter is not limited to a regular shape such as a circle, square, or triangle, but may be other irregular shapes.
Optionally, the cross-sectional shape of the filter is adapted to the first pipe 133 so that the condensed water entering the first pipe 133 first passes through the filter and the filtered condensed water flows into the nozzle 132.
