[0038] Reference Figures 1-7 An embodiment of the present application shows a vertical explosion-proof air conditioner indoor unit, which comprises a cabinet 1, a fan 3, an evaporator 2, a humidifying assembly 4 and a recovery tank 5. The cabinet 1 is formed with an upper and lower distribution refrigeration cavity 11 and an air guiding cavity 12. The cabinet 1 is provided with an air outlet 13 corresponding to the position of the refrigeration cavity 11 and an air inlet 14 corresponding to the position of the air guiding cavity 12. The fan 3 is arranged in the air guiding cavity 12, and the output end of the fan 3 is communicated with the refrigeration cavity 11. The evaporator 2 is arranged in the refrigeration cavity 11, and the evaporator 2 is arranged between the output end of the fan 3 and the air outlet 13. The humidifying assembly 4 comprises a water tank 41, a pump (not shown) and a water supply pipe 42. The water tank 41 and the pump are arranged in the air guiding cavity 12. The first end of the water supply pipe 42 is connected to the water tank 41, and the second end extends into the refrigeration cavity 11 and is provided with an atomizing nozzle. The recovery tank 5 is arranged between the air guiding cavity 12 and the refrigeration cavity 11, and the recovery tank 5 is located below the evaporator 2. The recovery tank 5 is provided with a drain hole 511, and the drain hole 511 is communicated with the water tank 41 through a return pipe 6.

[0039] Specifically, when the fan 3 is working, external air is introduced into the air guide cavity 12 through the air inlet 14 and is sent into the refrigeration cavity 11, passes through the evaporator 2, and completes heat exchange with the evaporator 2, so that the temperature of the air is reduced and the air is output from the air outlet 13, thereby achieving refrigeration. When humidification is required, the pump works to send water in the water tank 41 to the atomizing nozzle along the water delivery pipe 42, the atomizing nozzle atomizes the water to form very small water droplets, and the air carries the water droplets out of the air outlet 13 to the indoor; wherein when the air passes through the evaporator 2, the air releases heat, and the water vapor in the air condenses and adheres to the evaporator 2, and when the condensation forms a certain scale, it flows and drops along the evaporator 2 into the recovery tank 5 and flows to the water tank 41 through the drain pipe and the return pipe 6.

[0040] The vertical explosion-proof air conditioner indoor unit recovers the condensed water through the recovery tank 5 and the water tank 41 when performing normal refrigeration or dehumidification, and facilitates proper utilization of the condensed water when humidification is performed.

[0041] The fan 3 is a volute fan 3. The volute fan 3 has a compact structure, which is conducive to reducing the volume of the cabinet 1.

[0042] The above scheme is specifically as shown in Figure 4 The evaporator 2 is inclined in the refrigeration cavity 11 and divides the refrigeration cavity 11 into a first refrigeration sub-cavity 111 and a second refrigeration sub-cavity 112, the output end of the fan 3 is communicated with the first refrigeration sub-cavity 111, and the air outlet 13 is located on the side wall corresponding to the second refrigeration sub-cavity 112.

[0043] The atomizing nozzle is arranged on one side of the evaporator 2. If the air power of the fan 3 is small, the atomized droplets sprayed by the atomizing nozzle may not be all output outside the cabinet 1; the atomized droplets can adhere to the evaporator 2, and when the atomized droplets accumulate to a certain scale, the atomized droplets flow and drop along the evaporator 2 into the recovery tank 5 and are returned to the water tank 41.

[0044] In some embodiments, in order to enable the recovery tank 5 to better collect the condensed water dropped from the evaporator 2, as shown in Figures 4-6 The recovery tank 5 includes a bottom plate 51, first and second vertical plates 52 and 53 are respectively arranged on both sides of the bottom plate 51, a tank body structure is formed between the first vertical plate 52, the bottom plate 51 and the second vertical plate 53, a guide inclined plate 54 is extended from the top of the first vertical plate 52 and is connected to the lower end of the evaporator 2, end plates 55 are respectively arranged at both ends of the bottom plate 51, the end plates 55 are provided with connecting holes 551 for connecting with the cabinet 1, and a drain hole 511 is arranged on the bottom plate 51.

[0045] The fan 3 is a volute fan 3. The volute fan 3 has a compact structure, which is conducive to reducing the volume of the cabinet 1. Figure 6As shown, the guide inclined plate 54 is extended on one side of the evaporator 2 and extends upward for a certain distance, so that the condensed water dripping on the evaporator 2 can all fall into the recovery tank 5, avoiding dripping into the cabinet 1. The recovery tank 5 is connected with the cabinet 1 through the end plates 55 at both ends, and the connecting holes 551 on the end plates 55 are detachably fixed with the cabinet 1 through a bolt assembly, ensuring the stable position of the recovery tank 5 in the cabinet 1. When the water in the water tank 41 overflows, the condensed water in the recovery tank 5 reaches a certain amount, which will bring a certain bearing pressure to the recovery tank 5, and the stable mounting structure of the recovery tank 5 can ensure the stable bearing of the condensed water.

[0046] In some embodiments, as shown in Figure 4 and Figure 5 As shown, the water supply pipe 42 extends from the side where the second vertical plate 53 of the recovery tank 5 is located to the second refrigeration sub-cavity 112, and the water supply pipe 42 is wrapped with a protective cotton sleeve 45. In this way, the protective cotton sleeve 45 can prevent the water supply pipe 42 from being scratched by the second vertical plate 53 and prevent the water supply pipe 42 from being damaged.

[0047] In some embodiments, as shown in Figure 2 and Figure 7 As shown, the cabinet 1 is provided with a cabinet door 15, the air inlet 14 is arranged on the cabinet door 15, the lower end of the cabinet door 15 is provided with a bearing plate 151, and the bearing plate 151 is provided with a filter screen assembly 7. The air entering the cabinet 1 is filtered through the filter screen assembly 7 to prevent dust from entering, so that the condensed water generated by the air on the evaporator 2 is relatively pure. The filter screen assembly 7 is arranged on the bearing plate 151 of the cabinet door 15, which is convenient to replace, and when the cabinet door 15 is opened, the filter screen assembly 7 can be removed at the same time, which is convenient for maintenance and repair work.

[0048] In some embodiments, as shown in Figure 5 As shown, the water tank 41 is provided with a water inlet 44. When the water in the water tank 41 is insufficient, water can be added to the water tank 41 through the water inlet 44; wherein the water inlet 44 can be manually filled with water, or the water inlet 44 can be connected to an external water supply system (not shown) for automatic water filling.

[0049] In some embodiments, the material of the vertical explosion-proof air conditioner indoor unit is explosion-proof material to prevent the occurrence of dangerous situations such as electric sparks; and it adopts D-type explosion-proof method, and the electronic components of the vertical explosion-proof air conditioner indoor unit are arranged in an external explosion-proof box (not shown) to ensure stable operation in a dangerous environment.

[0050] To sum up, the application provides a vertical explosion-proof air conditioner indoor unit, which is designed with a humidifying assembly 4 and a recovery groove 5, so as to realize the humidifying function of the vertical explosion-proof air conditioner indoor unit, and to recover the condensed water generated on the evaporator 2, so that the condensed water is returned to the water tank 41 and utilized, thereby reducing the waste of water resources and meeting the modern environmental protection and energy saving concept; the internal structure of the vertical explosion-proof air conditioner indoor unit is compact and reasonable, and the design of the recovery groove 5 does not adversely affect the size of the vertical explosion-proof air conditioner indoor unit.
