Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to a water storage device and a mobile air conditioner. Background Art

[0002] When a mobile air conditioner is cooling, the condensed water generated on the evaporator generally drains into the water storage tank at the base, and then the shaded pole motor drives the water wheel to disperse the condensed water and pour it on the fins of the condenser, causing the condensed water to vaporize and then be discharged outdoors through the air duct.

[0003] However, during actual construction, in a high-humidity environment, excessive condensed water can easily cause water full protection for the mobile air conditioner. When the water level in the base water storage tank exceeds the safety value, it is necessary to control the compressor to stop running. When the water is consumed below the safety line in the water storage tank, the compressor can continue to run. This process will cause the compressor to start and stop frequently, reducing the user experience. Summary of the Invention

[0004] The problem solved by the present invention is the technical problem that the mobile air conditioner is extremely prone to water full protection, resulting in frequent start and stop of the compressor, and achieving the technical effect of reducing the probability of the air conditioner tripping due to water full.

[0005] To solve the above problems, the present invention provides a water full protection device. The water full protection device is used for a mobile air conditioner. The mobile air conditioner is provided with a water collection device. The water full protection device includes: a water storage device, which is arranged on the mobile air conditioner and connected to the water collection device; a first sensing device, which is arranged on the water collection device; a second sensing device, which is arranged on the water storage device; and a control device, which is respectively connected to the first sensing device and the second sensing device.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the water full protection device further increases the accommodation space for condensed water in the mobile air conditioner through the water storage device, and a first sensing device and a second sensing device are arranged in two water collection devices for condensed water respectively, which is convenient for detecting the content of condensed water in the two parts, reacting in time and controlling in time. If the water is full, the sensor can send a signal in time, or control the transfer of condensed water between the water collection device and the water storage device, and finally protect the mobile air conditioner from water full first.

[0007] In an example of the present invention, the water storage device includes: a water tank, which is arranged at the bottom of the evaporator of the mobile air conditioner; a water inlet device, which connects the water tank and the water collection device; a water outlet device, which connects the water tank and the water collection device; and a water injection port, which extends from the top surface of the water tank.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The water collection device and the water storage device are connected into a circular water circulation system through the water inlet device and the water outlet device. Water can circulate between the water collection device and the water storage device. When there is too much water in the water collection device and too little water in the water storage device, the water inlet device is controlled to send the water in the water collection device into the water storage device; when there is too little water in the water collection device and too much water in the water storage device, the water outlet device is controlled to send the water in the water storage device into the water collection device; when there is too much water in both the water collection device and the water storage device, a signal is sent through the sensing device, and after the control device receives it, an alarm is issued to remind the user to manually disassemble and install the water collection device to pour out the water. When there is too little water in both the water collection device and the water storage device, the water collection device can continuously obtain condensed water through the evaporator and the condenser. If the collection of condensed water is too slow, manual filling can be carried out through the water injection port provided on the water tank. Such a setting facilitates ensuring that the water in the mobile air conditioner will not be full, and thus will not cause frequent start and stop of the compressor.

[0016] Compared with the prior art, the technical effects achieved by adopting this technical solution are: through the first groove and the second groove, the accommodation space in the water collection device is increased.

[0017] In an example of the present invention, the groove wall is provided with a notch, the notch penetrating the groove wall to connect the first groove and the second groove.

[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are: a notch is provided between the first groove and the second groove to connect the two, facilitating the sensor in the second groove to measure the water level, and further increasing the water collection space in the water collection device.

[0039] In this embodiment, a water full protection device 100 is provided. This device is used for a mobile air conditioner 200, is arranged on the mobile air conditioner 200, and is used for water full protection of the mobile air conditioner 200. In the existing mobile air conditioners 200, a water collection device 210 is provided to collect condensed water, but the accommodation space of the water collection device 210 is insufficient, often resulting in water overflow when full. Generally, the water collection device 210 is arranged at the bottom of the mobile air conditioner 200 to facilitate the collection of condensed water. Further, a condenser 230 is generally arranged at the bottom of the evaporator 220 of the mobile air conditioner 200. A water leakage hole is provided at the bottom of the evaporator 220 to allow the condensed water to flow out. The condenser 230 is set to be strip-shaped and is arranged on both sides of the water leakage hole of the evaporator 220 to divert the condensed water exposed by the water leakage hole into the water collection device 210 and condense it. The water collection device 210 is specifically arranged below the condenser 230.

[0040] Therefore, for the water full protection device 100 proposed in this case, the water storage device 110 can further improve the capacity for condensing water based on the water collection device 210. The water storage device 110 can be arranged at the bottom of the evaporator 220, or can be arranged inside the water collection device 210 or at the bottom of the water collection device 210. Preferably, the water storage device 110 is arranged at the bottom of the evaporator 220. The water storage device 110 is connected to the water collection device 210 to convey the condensing water in the water collection device 210 into the water storage device 110. A sensing device 120 is arranged inside the protection device 100 for detecting the water volume and timely transmitting the information of water full. Specifically, the sensing device 120 includes a first sensing device 121 and a second sensing device 122 respectively.

[0041] When the first sensor 121 detects that there is too much condensing water in the water collection device 210, it will transmit the signal to the control device 130, and the control device 130 controls the water storage device 110 to suck out a part of the water in the water collection device 210 to prevent the water in the water collection device 210 from being full. When the second sensor 122 detects that there is too much water in the water storage device 110, the second sensing device 122 will send the signal to the control device 130, and the control device 130 controls the water storage device 110 to release a part of the water. Specifically, the water released from the water storage device 110 can be released into the water collection device 210, or can also be released into other containers or positions. When both the first sensing device 121 and the second sensing device 122 transmit the water full information, a warning signal can be sent through the control device 130 to remind the user to pour out the water in the water collection device 210 and the water storage device 110.

The first water level mark is at the lowest end of the column, and the third water level mark is at the uppermost end of the column.

[0071] When the first buoy 121c is below the first water level mark and this state is stable for more than 1 minute, the first float switch 121a sends a signal to the control device 130 to drive the valve 113b on the water tank 111 to open. Under the action of gravity, the water tank 111 supplies water to the second groove 213. If there is no water in the water tank 111, it can prompt the user to inject water into the water tank 111. The water on the second groove 213 is driven by the driving device 240 to drive the water impeller 250 to break up and then poured on the fins of the condenser 230 to vaporize, improving the heat exchange capacity of the condenser 230, so that the air conditioner 200 achieves the effect of rapid cooling. When the first buoy 121c reaches the water level 1 and this state is stable for 1 minute, the first sensing device 121 sends a signal to the control device 130 to drive the valve 113b on the water tank 111 to close and stop supplying water to the second groove 213;

[0072] In the refrigeration state of the air conditioner, when the first buoy 121c reaches the second water level mark and the state is stable for 1 minute, the first buoy 121c sends a signal to the main control to drive the water pump 112a to start working, continuously pumping the water on the first groove 212 into the water tank 111 for storage. When the first buoy 121c drops below the second water level mark and the state is stable for 1 minute, the first buoy 121c sends a signal to the control device 130 to drive the water pump 112a to stop working.

[0073] In the refrigeration state of the air conditioner, when the first buoy 121c reaches the third water level mark and the state is stable for 1 minute, the first buoy 121c sends a signal to the control device 130, the compressor stops running, and the water pump 112a continues to work. When the first buoy 121c drops below the third water level mark, the first buoy 121c sends a signal to the control device 130, the compressor restarts, and the water pump 112a continues to work until the first buoy 121c is below the second water level mark and the state is stable for 1 minute, then the first buoy 121c sends a signal to the control device 130 to drive the water pump 112a to stop working.

[0074] Whether the water tank 111 stores water is controlled by the second sensing device 122 in the water tank 111. When the second buoy 122d in the water tank 111 is lower than the safety mark 122c, water can be continuously stored. When the second buoy 122d is higher than the safety mark 122c, the micro switch at the top of the water tank 111 closes. At this time, the second sensing device 122 sends a signal to the control device 130 to drive the water pump 112a to stop working, and the water tank 111 no longer stores water.

[0075] In the refrigeration state of the air conditioner, when the second buoy 122d in the water tank 111 is higher than the safety mark 122c, and the first buoy 121c of the water collection device 210 reaches the third water level mark and the state is stable for 1 minute, the control panel prompts the user to clean the water stored in the water tank 111 in time and directly remove the water tank to pour the water to prevent the whole machine from having a water full protection.

[0076] Among them, in the whole process, the priority of driving the water pump 112a is that the safety mark 122c is preferred to the second water level mark.
