[0002] Window air conditioners are popular in overseas markets with high labor costs because of their easy installation. However, when the air conditioner is in cooling mode, it will produce a lot of condensed water. When the condenser is frosted and defrosted during heating, it will also produce a lot of defrost water. Once the water inside the air conditioner exceeds the set capacity, the user needs to connect an external drain pipe to drain it. However, since the window unit is partially external and suspended in the air, this operation is relatively dangerous, and regulations in some regions prohibit the air conditioner from draining water externally. Therefore, the market urgently needs an automatic water-removing window air conditioner that does not require manual intervention to meet user needs.

[0003] Patent No. CN202222987936.0 discloses a compressor water removal device, which uses the compressor's own heat to evaporate the chassis condensed water, but the temperature of the compressor outer wall under heating conditions is not enough to remove all condensed water or defrost water.

[0044] Embodiment 1

[0045] See also Figure 1-4As shown, this embodiment discloses a water removal device, which is applied inside the air conditioner and can process and remove the accumulated water inside the air conditioner without human intervention, and avoids the accumulation of water inside the air conditioner causing the mechanical or electronic components to get damp and shorten the service life of the air conditioner.

[0046] The dewatering device of this embodiment includes: a water storage tray 1 and a heating element 2; the water storage tray 1 is provided with a water storage tank 11, and the water storage tank 11 is used to collect air-conditioning accumulated water; the heating element 2 is provided with a hot end 21, the hot end 21 faces the water storage tank 11, and the hot end 21 is used to generate heat to evaporate the accumulated water.

[0047] The water removal device of the present embodiment is provided with a water storage tank 11 and a heating element 2. The condensed water and defrost water collected in the water storage tank 11 are evaporated by transferring heat through the hot end 21, thereby removing the accumulated water inside the air conditioner without the user having to drain the accumulated water. This solves the drainage problem of the window air conditioner, improves the overall performance and user experience of the air conditioner, and meets the needs of users and the market for intelligent, safe and convenient home appliances.

[0048] Specifically, the hot end 21 is provided with a first radiator 22, and the first radiator 22 extends from the hot end 21 toward the water storage tank 11. The first radiator 22 increases the contact area between the hot end 21 and the air inside the air conditioner, and is used to improve the heat transfer efficiency of the hot end 21, which helps the heat of the hot end 21 to be evenly and quickly conducted, thereby accelerating the evaporation of accumulated water, ensuring the effective use of heat, and improving the water removal efficiency of the water removal device. Furthermore, the first radiator 22 lengthens the heat transfer path, which is conducive to the transfer of heat to the water storage tank 11 and other components in the air conditioner, such as the condenser 7, which helps to achieve non-stop defrosting and ice-melting of the water storage pan 1 under low-temperature heating conditions.

[0049] Specifically, the first radiator 22 includes a plurality of first radiator fins, which are evenly distributed on the hot end 21, and there are gaps between adjacent first radiator fins. There is a gap between every two first radiator fins, so that each first radiator fin can be in full contact with the air, which reduces material consumption and improves the heat dissipation performance of the first radiator 22; the first radiator fins are small and light, making the first radiator 22 easy to install and maintain, and also reducing the overall weight and cost of the dehydration device, and can play a better heat dissipation function when the internal space of the air conditioner is limited.

[0050] Furthermore, the first heat sink is made of a metal material with thermal conductivity. The metal material with thermal conductivity enables the first heat sink to withstand high temperature and humid environments, thereby improving the reliability and stability of the water removal device in long-term use.

[0051] Specifically, the heating element 2 is provided with a cold end 23, which is provided at one end of the heating element 2 away from the water storage tank 11. The heating element 2 generates heat when working, and the heat is transferred outward from the hot end 21, while the cold end 23 is relatively low in temperature and is used to dissipate heat to ensure the service life of the heating element 2, or to cool down other heat-generating components in the air conditioner, such as the compressor 6, the electrical box 8, etc.

[0052] Specifically, the cold end 23 is provided with a second radiator 24, and the second radiator 24 extends from the cold end 23 in a direction away from the water storage tank 11. The second radiator 24 increases the contact area between the cold end 23 and the air inside the air conditioner, and is used to improve the heat exchange efficiency between the cold end 23 and the air inside the air conditioner, which helps the heating element 2 to quickly dissipate heat, or quickly cool down the heat-generating components in the air conditioner.

[0053] Specifically, the second radiator 24 includes a plurality of second radiator fins, which are evenly distributed on the cold end 23, and there are gaps between adjacent second radiator fins. There is a gap between every two second radiator fins, so that each second radiator fin can be in full contact with the air, which reduces material consumption and improves the heat exchange efficiency between the second radiator 24 and the air; the second radiator fins are small and light, making the second radiator 24 easy to install and maintain, and also reducing the overall weight and cost of the dehydration device.

[0054] Furthermore, the second heat sink is made of a metal material with thermal conductivity. The metal material with thermal conductivity enables the second heat sink to withstand high temperature and humid environments, thereby improving the reliability and stability of the water removal device in long-term use.

[0055] In this embodiment, the heating element 2 is a semiconductor thermoelectric cooling sheet. The semiconductor thermoelectric cooling technology adopts the principle of the Peltier effect, that is, direct current passes through two different thermoelectric materials, such as N-type and P-type semiconductor materials, and absorbs or releases heat at the joint, so that one end of the heating element 2 absorbs heat to become the cold end 23, and the other end releases heat to become the hot end 21, thereby realizing the cooling of the cold end 23 and the heating of the hot end 21. Therefore, this embodiment adopts semiconductor thermoelectric cooling technology to realize the heating of the hot end 21, so that the accumulated water evaporates, and avoids the accumulated water from overflowing the water storage tank 11 and damaging the air conditioner. At the same time, the cold end 23 is cooled, so that the heat-generating components such as the compressor 6 and the electrical box 8 are cooled, and the second radiator 24 accelerates the cooling of the heat-generating components, avoiding the overheating of the heat-generating components and causing the air conditioner failure, and ensuring the overall stability and service life of the air conditioning system.

[0056] It is understandable that in other embodiments, a combination of an electric heating structure and a heat dissipation structure may be used to replace the semiconductor thermoelectric cooling sheet. Specifically, the electric heating structure is used to generate heat to form a hot end 21 to achieve evaporation of accumulated water, such as an electric heating wire, an electric heating film or a PTC ceramic heating element; the heat dissipation structure is used to reduce the temperature to form a cold end 23 to achieve heat dissipation of the heating component, such as a fan or a liquid cooling system.

[0057] Specifically, the dewatering device of this embodiment further includes: a liquid level detector 3; the liquid level detector 3 is used to detect the liquid level of the water storage tank 11. The liquid level detector 3 is used to detect the change of the liquid level of the water storage tank 11, and then control the heating element 2 to turn on or off to evaporate the accumulated water so that the water storage tank 11 reaches a preset liquid level.

[0058] Specifically, the dewatering device of this embodiment further includes: a circulation pipe 4 and a circulation pump 5; the circulation pump 5 is arranged on the circulation pipe 4, and is used to drive the fluid in the circulation pipe 4 to circulate along the circulation pipe 4; the circulation pipe 4 extends to the hot end 21. Driven by the power of the circulation pump 5, the fluid in the circulation pipe 4 flows through the hot end 21 area and circulates continuously. The fluid in the circulation pipe 4 can continuously and dynamically absorb heat from the hot end 21 and bring the heat to other areas, thereby realizing continuous heat transfer, which helps to transfer heat to the surface of the condenser 7 and the accumulated water when the circulation pipe 4 extends to the condenser 7 and the water storage tank 11, so as to realize the defrosting of the condenser 7 and the ice melting of the water storage pan 1 under the condition of low-temperature heating. The working state of the circulation pump 5 of this embodiment can be intelligently adjusted according to the signal of the liquid level detector 3. For example, when the liquid level in the water storage tank 11 is high, the circulation pump 5 is turned on or accelerated to promote the evaporation of the accumulated water. When the liquid level reaches the preset value, the circulation pump 5 slows down or stops to save energy and avoid excessive evaporation.

[0059] Specifically, the circulation pipe 4 is arranged between the hot end 21 and the first radiator 22. The circulation pipe 4 is directly placed between the hot end 21 and the first radiator 22, which can ensure that the heat generated by the hot end 21 can be quickly and efficiently transferred to the fluid in the circulation pipe 4, reducing the path and obstacles of heat transfer, so that the heat can be diffused to the entire dewatering system more quickly, thereby improving the overall heat transfer efficiency.

[0060] Embodiment 2

[0061] See also Figure 1-4 As shown, this embodiment discloses an air conditioner, including the water removal device of embodiment one.

[0062] The air conditioner of this embodiment introduces a water removal device, which evaporates accumulated water by heating without human intervention, thereby realizing the air conditioner's external exhaust-free water removal and enhancing the heat dissipation of the compressor 6 and the electrical box 8 during operation, greatly improving the overall performance and user experience of the air conditioner, thereby improving the market competitiveness of the air conditioner product.

[0063] Specifically, the air conditioner of this embodiment further includes: a compressor 6, a condenser 7 and an electrical box 8; the compressor 6, the heating element 2 and the water storage tank 11 are arranged between the electrical box 8 and the condenser 7, and the circulation pipe 4 extends to the side wall of the condenser 7 and the water storage tank 11. The water storage tank 11 is arranged below the heating element 2, and the heating element 2 is started to heat the hot end 21, so that the accumulated water in the water storage tank 11 evaporates, thereby achieving the removal of accumulated water in the air conditioner. The circulation pipe 4 extends to the side wall of the condenser 7 and the water storage tank 11, which helps to transfer the heat of the hot end 21 to the surface of the condenser 7 and the accumulated water through the fluid, so as to achieve the defrosting of the condenser 7 and the defrosting of the water storage pan 1 without stopping under the condition of low-temperature heating.

[0064] Among them, the compressor 6 is used to compress the refrigerant vapor, so that the temperature and pressure of the refrigerant are increased, and then the refrigerant can effectively release heat and condense into liquid in the condenser 7 to achieve a refrigeration effect. The condenser 7 is used to receive the high-temperature and high-pressure refrigerant vapor from the compressor 6, and make the refrigerant vapor exchange heat with the outdoor air or cooling water, release heat and condense into a liquid, ensuring that the refrigerant can be discharged to the outside with the heat absorbed from the room, thereby realizing the refrigeration function of the air conditioner. The electrical box 8 is a centralized installation area for the electrical components inside the air conditioner, such as the control circuit, protection device, terminal block and other key components, which can protect these electrical components from interference and damage from the external environment. Furthermore, the control circuit in the electrical box 8 can accurately control and adjust the compressor 6 and other components according to the temperature and humidity parameters set by the system or the user to achieve the best refrigeration effect.

[0065] Specifically, the compressor 6, the condenser 7 and the electrical box 8 are installed on the water storage pan 1. That is, in this embodiment, the water storage pan 1 is the air conditioner chassis, which is used to install components. The chassis is provided with a water storage tank 11 to collect condensed water generated by refrigeration operation, defrost water or other accumulated water generated by heating operation, which simplifies the structure of the air conditioner, reduces material consumption, and helps to reduce the assembly difficulty and production cost of the air conditioner. It can be understood that in other embodiments, the water storage pan 1 is a water storage component independent of the air conditioner chassis, embedded in the chassis, and located below the heating component 2.

[0066] Specifically, the edge of the water storage tank 11 is inclined. The inclination of the notch of the water storage tank 11 helps to guide the accumulated water to flow quickly to the bottom of the water storage tank 11, so as to facilitate centralized treatment of the accumulated water.

[0067] In this embodiment, the air conditioner is a window air conditioner, and the heating element 2 and the compressor 6 are arranged in sequence from the side vent of the window air conditioner to the inside of the window air conditioner; the electrical box 8 is arranged on the side of the window air conditioner close to the outdoor fan. In the window air conditioner, the side vent is located on the left or right side surface. When the air conditioner is running, under the negative pressure of the outdoor fan, the air enters the air conditioner through the side vent, exchanges heat with the cold end 23 and the second radiator 24 to form cold air, and the cold air is discharged after passing through the compressor 6 and the electrical box 8, thereby taking away the heat, improving the heat dissipation efficiency of the heating components, and ensuring the normal operation of the air conditioner.

[0068] It is understandable that in other embodiments, the positions of the compressor 6, the condenser 7, the electrical box 8 and the heating element 2 can be adjusted according to actual needs or the type of air conditioner.

[0069] Furthermore, in other embodiments, the first radiator 22 can extend to the side vents. While ensuring that the first radiator 22 transfers heat from the hot end 21, the first radiator 22 extending to the side vents can help accelerate the heat dissipation of the hot end 21 to extend the service life of the heating element 2.

[0070] Embodiment 3

[0071] See also Figure 1-7 As shown, this embodiment discloses an air conditioner dehydration method, which is performed by the air conditioner of embodiment 2 and includes the following steps:

[0072] Step S1: when receiving a cooling mode instruction, obtaining the liquid level of the water storage tank 11, and turning on or off the heating element 2 according to the liquid level of the water storage tank 11, so that the water storage tank 11 reaches a first preset liquid level.

[0073] For step S1, it is ensured that in the cooling mode, the air conditioner can automatically start or shut down the heating element 2 according to the liquid level of the water tank 11, thereby effectively dealing with the accumulated water in the water tank 11 and preventing excessive water accumulation. At the same time, the water tank 11 is kept within the preset safe liquid level range to ensure the normal operation of the air conditioner.

[0074] See also Figure 6 As shown, step S1 includes the following specific steps:

[0075] Receiving a cooling mode instruction, starting the compressor 6, and entering the cooling mode;

[0076] Monitor the liquid level of the water storage tank 11, and when the liquid level of the water storage tank 11 is greater than a first liquid level threshold, turn on the heating element 2 to heat the hot end 21;

[0077] Detecting the liquid level of the water storage tank 11 to determine whether the liquid level of the water storage tank 11 is greater than a first liquid level threshold and less than a second liquid level threshold, if so, the hot end 21 stops heating, otherwise the hot end 21 continues heating;

[0078] Waiting for compressor 6 to shut down;

[0079] The liquid level of the water storage tank 11 is monitored, and when the liquid level of the water storage tank 11 is less than or equal to the first preset liquid level, the heating element 2 is turned off.

[0080] More specifically, in this embodiment, the depth of the water tank 11 is 30 mm, the first liquid level threshold is 15 mm, the second liquid level threshold is 25 mm, and the first preset liquid level is 0 mm. In specific implementation, the cooling mode causes the condenser 7 to generate condensed water. If the condensed water is too little, the airflow generated by the fan will throw off the condensed water on the condenser 7, and the condensed water will fall into the water tank 11. However, if the condensed water is too little, the water pumping performance of the fan cannot reach the optimal state. If the condensed water is too much, it will exceed the capacity of the water tank 11 and easily overflow the water tank 11. Therefore, the optimal water level range of the preset condensed water is between the first liquid level threshold and the second liquid level threshold. When the liquid level detector 3 detects that the condensed water reaches the first liquid level threshold, the heating element 2 starts to work, and the hot end 21 evaporates the condensed water in the water tank 11, so that the overall water level of the water tank 11 is maintained within the optimal water pumping height range of the fan, which can not only maintain a high overall performance, but also avoid the user from draining the water by himself. When the liquid level detector 3 detects that the liquid level of the water storage tank 11 is at the first liquid level threshold and the second liquid level threshold, the heating element 2 stops working. After the compressor 6 stops working, the heating element 2 resumes working to heat the hot end 21 until all the accumulated water in the water storage tank 11 is evaporated, so as to prevent the condensed water from being retained in the water storage pan 1 for a long time and generating odor.

[0081] Step S2: When receiving the instruction of the heating mode, the outdoor temperature and the liquid level of the water storage tank 11 are obtained, and the heating element 2 is turned on or off according to the outdoor temperature to make the water storage tank 11 reach a second preset liquid level.

[0082] For step S2, in the heating mode, the air conditioner needs to absorb heat from the outdoor environment. The lower the outdoor temperature, the lower the heat exchange efficiency of the air conditioning system, because it needs to overcome a larger temperature difference to extract heat. When the outdoor temperature is too low, the surface of the condenser 7 is prone to frost, which will greatly reduce its heat exchange efficiency and even cause the system to fail to operate normally. At the same time, the accumulated water in the water tank 11 may also freeze due to the low temperature. Therefore, by monitoring the outdoor temperature, the heat exchange efficiency of the system can be understood in real time, so as to make corresponding dehydration, defrosting, and ice-melting adjustments.

[0083] See also Figure 7 As shown, step S2 includes the following specific steps:

[0084] Receiving a heating mode instruction, starting the compressor 6, and entering the heating mode;

[0085] Monitor the outdoor temperature. When the outdoor temperature is lower than a first temperature threshold, the heating element 2 generates heat and the circulation pump 5 is turned on.

[0086] Monitor the outdoor temperature, and when the outdoor temperature is greater than a second temperature threshold, turn off the circulation pump 5;

[0087] The liquid level of the water storage tank 11 is monitored, and when the liquid level of the water storage tank 11 is less than or equal to a second preset liquid level, the heating element 2 stops heating.

[0088] Among them, the second temperature threshold is greater than the first temperature threshold. More specifically, in this embodiment, the second preset liquid level is 0 mm. In specific implementation, the heating mode causes the condenser 7 to frost and the water storage pan 1 to freeze. When the outdoor temperature reaches the first temperature threshold, the heating element 2 is started to heat the hot end 21, and the fluid in the circulation pipe 4 is circulated through the circulation pump 5 to achieve defrosting of the condenser 7 and defrosting of the chassis. When the outdoor temperature reaches the second temperature threshold, the circulation pump 5 stops working to complete the defrosting and defrosting action, while the hot end 21 continues to heat until the liquid level detector 3 detects that the defrosting water in the water storage tank 11 is completely evaporated, and the heating element 2 stops working to avoid water accumulation in the water storage tank 11 under low temperature conditions and affect the performance of the whole machine.

[0089] It is understandable that in other embodiments, the values ​​of the first liquid level threshold, the second liquid level threshold, the first preset liquid level, the first temperature threshold, the second temperature threshold and the second preset liquid level may be adjusted according to actual needs.

[0090] The present invention provides a water removal device, an air conditioner and an air conditioner water removal method, which evaporates condensed water and defrost water collected in a water storage tank by transferring heat through a hot end, thereby removing accumulated water inside the air conditioner without the need for a user to drain the accumulated water. This solves the water drainage problem of a window air conditioner, improves the overall performance of the air conditioner and the user experience, and meets the needs of users and the market for intelligent, safe and convenient home appliances.
