[0002] Air conditioners, as refrigeration appliances, have entered every household, especially in summer, when the usage rate of air conditioners is higher. The working principle of air conditioners is to use a compressor to compress the refrigerant in the pipeline into a high-temperature and high-pressure liquid and flow into the condenser for heat dissipation. Then, under the throttling and pressure reduction of the expansion valve, it enters the interior of the evaporator. The liquid refrigerant turns into a gas inside the evaporator and absorbs heat, so that the evaporator can achieve the effect of cooling the indoor air. Existing air conditioners will produce a large amount of condensed water during the refrigeration process. The traditional way of treating the condensed water is to directly discharge it to the outside, and the condensed water is not utilized. Based on the above situation, it is necessary to design an air conditioning condensed water recycling energy-saving device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0021] refer to Figure 1 and Figure 2In order to enable those skilled in the art to understand the innovative features of the present invention, the prior art of the present invention is first described. The existing air conditioner includes an outdoor unit assembly 1 and an indoor unit assembly 2, wherein the outdoor unit assembly 1 includes an outdoor unit housing 103 with a heat dissipation vent, a compressor 101 inside the outdoor unit housing 103, a condenser 102 at the output end of the compressor 101, and a cooling fan 105 for dissipating heat from the condenser 102; the indoor unit assembly 2 includes an indoor unit housing 203, an evaporator inside the indoor unit housing 203, and an evaporator inside the indoor unit housing 203. 201, and the axial flow fan 202 for driving the indoor air through the evaporator 201. During the cooling process, the compressor 101 compresses the refrigerant in the pipeline into a high-temperature and high-pressure liquid refrigerant through compression, and enters the interior of the condenser tube 102 to cooperate with the cooling fan 105 for heat dissipation. When the cooling fan 105 is dissipating heat, it takes away the heat on the surface of the condenser tube 102 through the flow of air, and then blows it out from the heat dissipation port 104 of the outer shell 103. The refrigerant after heat dissipation passes through the expansion valve (the medium-temperature and high-pressure refrigerant is throttled and depressurized). , becomes a low-pressure state) enters the interior of the evaporator 201, and the refrigerant entering the evaporator 201 becomes a gas due to the sudden drop in pressure, absorbing the surrounding heat, and the axial flow fan 202 drives the indoor air to the surface of the evaporator 201 to cool the air, and blows it out from the air outlet 204 of the inner machine shell 203. This process is the existing air conditioning refrigeration process. In the existing air conditioning refrigeration process, when the evaporator 201 of the inner machine assembly 2 cools the air, a large amount of condensed water will be generated in the air, which is collected by the water collecting box 3 under the evaporator 201. After being collected, the air is discharged to the outside through the drain pipe 301. Directly discharging the air to the outside causes waste, and the existing air conditioner often has a worse cooling effect when the weather is hotter. The main reason is that the hotter the weather, the worse the heat dissipation effect of the condenser 102, and the worse the indoor cooling effect. Therefore, when cooling is performed in the hot summer, the indoor cooling effect is poor due to the poor heat dissipation effect of the condenser 102, and the compressor 101 needs to work for a long time, wasting a lot of electricity. Based on the above situation, the present invention makes the following improvements to the existing air conditioner.

[0022] refer to Figure 3-Figure 5The main improvement of the present invention is that a condensed water utilization device 4 is added. The condensed water utilization device 4 is specifically implemented as follows: a water storage tank 402 is provided to be connected to the water collecting box 3 through a connecting pipe 401, so as to realize the centralized collection of the condensed water generated during the refrigeration process. At the same time, the condensed water is circulated through the circulation pipe box pump body 403. Specifically, the circulation pipe includes a conveying section 404, a heat absorbing section 408 and a heat dissipating section 406. The heat absorbing section 408 is attached to the outer wall of the condenser tube 102 and absorbs the heat of the condenser tube 102 through heat transfer. The heat absorbing section 408 can be in a straight line state or can be spirally wound and attached to the outer wall of the condenser tube 102. Preferably, a spiral heat absorbing section 408 is used. It can ensure an effective contact area and achieve sufficient heat absorption of the condenser 102. The heat dissipation section 406 can be set to a vortex shape, a serpentine shape (shown in a serpentine shape in the figure) or other shapes such as a mosquito coil shape. The heat absorbed by the water inside the heat absorption section 408 is dissipated by the heat dissipation fan 407 when passing through the heat dissipation section 406, thereby achieving a sufficient heat dissipation effect on the condenser 102, thereby achieving efficient cooling. Especially in summer, when the outdoor temperature is high and the heat dissipation effect of the condenser 102 is poor, the condenser 102 is efficiently cooled by the condensed water, thereby achieving an efficient cooling effect, avoiding the problem of power waste due to long-term operation of the compressor 101 due to poor indoor cooling effect.

[0023] Specifically, refer to Figure 6 , a controller 5 is also required. A temperature sensor 405 is also provided on the circulation pipe for monitoring the water temperature at the output end of the heat dissipation section 406 and transmitting the water temperature signal to the controller 5. The temperature sensor 405 can be installed on the conveying section 404 or on the heat dissipation section 406. A cooling fan 105 is also provided outside the heat dissipation section 406. When the water temperature inside the circulation pipe is high, the controller 5 is used to improve the working efficiency of the pump body 403 and the heat dissipation fan 407, that is, to improve the speed of the heat dissipation fan 407 and the conveying speed of the water pump, so that the water temperature inside the circulation pipe can be quickly dissipated, and the cooling effect on the condenser 102 is better. The better the heat dissipation of the condenser 102, the better the indoor cooling effect. It should be noted that the cooling fan 105 can also be controlled by the controller 5. When the water temperature is too high, the controller 5 also synchronously controls the speed of the cooling fan 105 to increase, thereby improving the heat dissipation effect of the condenser 102.

[0024] Furthermore, in order to ensure that the condensed water in the water collecting box 3 can be used by the water storage tank 402 first, the drain pipe 301 and the connecting pipe 401 connected to the inside of the water collecting box 3 are respectively set at different heights, that is, the input end height of the drain pipe 301 is higher than the input end height of the connecting pipe 401, to ensure that the water inside the water collecting box 3 first flows into the inside of the water storage tank 402, and the excess water inside the water collecting box 3 is then discharged from the drain pipe 301. In order to prevent the water inside the water storage tank 402 from still circulating when the liquid level is low, the height of the input end of the conveying section 404 is lower than the height of the output end of the heat dissipation section 406, to ensure that the water inside the water storage tank 402 can still circulate when the liquid level is low.

[0025] Specifically, a liquid level sensor is also provided inside the water tank 402 for monitoring the water level inside the water tank 402. When there is no water inside the water tank 402 or the water level is too low to meet the circulation of the circulating water pipe, the controller 5 does not control the pump body 403 and the cooling fan 407 to work. It is mainly suitable for air conditioning heating in winter. The functions of the evaporator 201 and the condenser 102 are interchanged, that is, the evaporator 201 is used for heating and the condenser 102 is used for cooling (through the adjustment of the four-way valve, this technology is existing technology and will not be elaborated in detail). At this time, the evaporator 201 will not produce condensed water, and the air conditioning condensed water recycling energy-saving device does not participate in the work.

[0026] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
