[0039] The embodiment of the present application discloses a card-type air conditioner.

[0040] See also Figure 1 , an embodiment of the card-type air conditioner provided in the embodiment of the present application includes:

[0041] A machine body 100 and an air conditioning module 200 disposed in the machine body 100;

[0042] An inspection port and a wire outlet are provided on the machine body 100, and an openable and closable inspection door panel 1 is installed on the inspection port; by providing an inspection port on the machine body 100 and setting an openable and closable inspection door panel 1, during maintenance, the internal pipe fixings and the like can be repaired by opening the inspection door panel 1, avoiding overall disassembly.

[0043] A waterproof junction box 2 connected to the outlet is installed on the body 100 at the outlet position. The waterproof junction box 2 is arranged outside the body 100, and the connection between the wiring in the air conditioning module 200 and the control circuit is placed outside the body 100 to facilitate the maintenance of the control circuit, etc., and avoid overall disassembly. The waterproof junction box 2 can be designed with reference to the existing waterproof junction box structure, and the details are not repeated. In addition, a sealing ring can be arranged around the outlet. When the waterproof junction box 2 is installed, it can be clamped with the body 100 to ensure the connection sealing between the outlet and the waterproof junction box 2.

[0044] The solution based on the above design makes the maintenance of the cassette air conditioner more convenient, which can improve the maintenance work efficiency by more than 5 times and save more than 5 times the maintenance cost.

[0045] The above is the first embodiment of the card-type air conditioner provided in the embodiment of the present application. The following is the second embodiment of the card-type air conditioner provided in the embodiment of the present application. For details, please refer to Figures 1 to 3 .

[0046] Based on the solution of the above embodiment 1:

[0047] Furthermore, with regard to the specific design of the machine body 100 and the air conditioning module 200 , the existing structure may be used for design. For example, the machine body 100 includes an outer shell 31 .

[0048] An upper cover plate 36 is provided on the top of the outer shell 31, and a shutter installation frame 32 is provided on the bottom of the outer shell 31. The shutter installation frame 32 is provided with outdoor air intake shutters 34, indoor air intake shutters 35 and outer shell bottom plate shutters 33.

[0049] The air conditioning module 200 includes a turbo fan 42, a fan motor 41, a water receiving tray 44, a filter 45, a water pump (not shown) and a condenser 43. The fan motor 41 is connected to the turbo fan 42 to drive the turbo fan 42 to rotate. The filter 45 is installed on the bottom plate louver 33 of the housing and is located directly above the indoor air inlet louver 35.

[0050] The water receiving pan 44 is installed above the filter 45, the turbofan 42 is installed above the water receiving pan 44, the condenser 43 is arranged around the turbofan 42, and its own converging water inlet pipe 431 and converging water outlet pipe 432 extend out of the outer shell, and a bottom plate insulation 46 is also provided between the water receiving pan 44 and the bottom plate louver 33 of the outer shell; the outdoor air inlet louver 34 and the indoor air inlet louver 35 respectively form an air inlet channel with the turbofan 42, and an air outlet channel is provided between the condenser 43 and the bottom plate louver 33 of the outer shell.

[0051] The water pump is installed in the outer shell 31, one end of which is connected to a water pump pipe (not shown) extending to the water receiving tray 44, and the other end is connected to a water outlet pipe extending out of the outer shell. The fan motor 41 drives the turbo fan 42 to rotate to form a negative pressure so that air is sucked into the air inlet channel. The air sucked by the turbo fan 42 enters the condenser 43 for cooling and then enters the air outlet channel to be blown out. The blowing process is filtered by the filter 45.

[0052] Taking the above structural design as an example, the inspection port is opened in the shell and corresponds to the installation position of the water pump, so as to facilitate the maintenance of the water pump. Taking the position of the water pump below the converging water inlet pipe 431 and the converging water outlet pipe 432 as an example, the inspection port can be opened on the wall where the converging water inlet pipe 431 and the converging water outlet pipe 432 are located, and is located below the converging water inlet pipe 431 and the converging water outlet pipe 432. It can be understood that the inspection port is opened at the installation position of the water pump corresponding to the air conditioning module 200.

[0053] Furthermore, a heat-insulating layer 37 is laid on the inner wall surface of the outer shell 31 , and the heat-insulating layer 37 may be a heat-insulating cotton material layer.

[0054] Further, with regard to the design of the inspection door panel 1, one side thereof is hinged to the machine body 100 through a hinge 11, and the other side thereof is detachably buckled with the machine body 100 through a buckle assembly 12. The buckle assembly 12 includes a first buckle provided on the inspection door panel 1 and a second buckle provided on the machine body 100, and the first buckle and the second buckle may be a conventional buckle structure that can be buckled by pressing, and there is no specific limitation.

[0055] Furthermore, after research, it was found that the outer water retaining edge 441 of the existing water receiving tray 44 is only 75 mm. Once a period of time has passed, the water receiving tray 44 becomes too dirty, causing the water pump to pump water too slowly, and condensed water in the water receiving tray 44 will easily overflow. For this reason, the present application designs the outer water retaining edge 441 of the water receiving tray 44 to be no less than 90 mm, preferably 90 mm.

[0056] Furthermore, after research, it was found that the existing converging water inlet pipe 431 and the converging water outlet pipe 432 are arranged in an upper and lower interval, but the upper and lower spacing is only 15 mm. Once the water inlet electric two-way valve fails and the related connecting pipes and fittings are leaking, water will penetrate into the electric two-way valve actuator and the insulation layer 37, and the insulation layer 37 at the interface between the converging water inlet pipe 431 and the converging water outlet pipe 432 is difficult to do well, which leads to an increase in maintenance costs. For this reason, the present application designs the upper and lower spacing between the converging water inlet pipe 431 and the converging water outlet pipe 432 to be not less than 80 mm, preferably 80 mm.

[0057] Furthermore, after research, it was found that the inner diameter of the existing water suction pipe is 8.5mm, and the inner diameter of the water outlet pipe is 10.5mm. The inner diameters are relatively small, which makes it easy to get blocked over time. Therefore, the inner diameters of the water suction pipe and the water inlet pipe are not less than 12mm, preferably not less than 12.7mm.

[0058] Furthermore, in order to prevent the dirt in the condensed water from being deposited and difficult to discharge, a stirring mechanism (not shown) may be added, with the stirring end extending into the water receiving tray 44 to stir the water in the water receiving tray 44 to break up the dirt, making it easier for the condensed water to carry the dirt with it when discharged.

[0059] The above is a detailed introduction to the card-type air conditioner provided in the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
