Except where otherwise indicated, the singular forms "a", "an" and "the" include plural referents.

[0045] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that an embodiment in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is expressly understood that the embodiments described herein are merely examples from a whole class of comparable embodiments which those skilled in the art will readily appreciate. The term "comprising" is intended to mean that there can be additional features which are not specifically described.

[0046] In order to better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings.

[0047] Referring to the drawings Figures 1 to 7 The present application provides an air water generator using recycled wastewater for heat dissipation, comprising an evaporator 1, a condenser 2, a water collecting tray 3, an air extractor 12, a water tank 4, a water pump 5, a self-cleaning filter element 6, a valve body 7 and a drain pipe 8.

[0048] The evaporator 1 and the condenser 2 are both provided with densely arranged fins, and the fins are arranged as shown in the accompanying drawings. Figure 3 The evaporator 1 and the condenser 2 are arranged side by side, the evaporator 1 absorbs heat from outside, and the condenser 2 emits heat to the outside. The air extractor 12 is located on the side of the condenser 2 away from the evaporator 1, and the air extracted by the air extractor 12 passes through the evaporator 1 and the condenser 2 in turn.

[0049] The water collecting tray 3 is provided with a first water collecting cavity 31 and a second water collecting cavity 32, the first water collecting cavity 31 is located below the evaporator 1, and the second water collecting cavity 32 is located below the condenser 2.

[0050] The water tank 4 is located below the water collecting tray 3 and is connected to the bottom of the first water collecting cavity 31. The water pump 5 is connected to the water tank 4 and the self-cleaning filter core 6 respectively. The self-cleaning filter core 6 in this embodiment is a conventional RO membrane filter core with automatic cleaning function. The self-cleaning filter core 6 has a waste water outlet end 61. The valve body 7 is connected to the waste water outlet of the self-cleaning filter core 6. The first end of the drain pipe 8 is connected to the valve body 7. The valve body 7 is an electromagnetic valve. The second end of the drain pipe 8 is located above the condenser 2.

[0051] The second end of the drain pipe is also connected to a water dispersing pipe 9. The water dispersing pipe 9 extends along the width direction of the condenser 2. A plurality of water outlets 91 are arranged along the length direction of the water dispersing pipe 9. The water outlets 91 are located above the condenser 2.

[0052] Specifically, as the evaporator 1 absorbs heat from outside, the outside air is sucked into the air water generator by the air blower 12. When the air flows through the evaporator 1, the water in the air is condensed into water droplets due to heat absorption. The water droplets fall into the first water collecting cavity 31 and then flow into the water tank 4 for collection and storage. The water pump 5 is used to extract the water in the water tank 4 and deliver it to the self-cleaning filter core 6. After filtration and purification by the self-cleaning filter core 6, the purified water enters the water tank for storage before being used. The waste water generated by the self-cleaning filter core 6 after automatic cleaning can flow to the upper part of the condenser 2 through the drain pipe 8 when the valve body 7 is opened. Then the waste water is dispersed by the water dispersing pipe 9, so that the waste water is scattered and falls on the fins of the condenser 2. At this time, as the condenser 2 emits heat to the outside, the waste water absorbs heat and evaporates. The water vapor can be sucked away by the air blower 12 and discharged to the outside. The process of waste water evaporation not only absorbs heat, but also cools the surface of the condenser 2. Moreover, after the waste water is dispersed by the water dispersing pipe 9, the condenser 2 has a larger contact area with the waste water, and the heat absorption effect is better. Therefore, the water cooling cooling method has higher efficiency than the air cooling method. The condenser 2 is cooled more quickly and more fully utilizes the waste water, rather than directly discharging the waste water, which leads to waste.

[0053] If there is too much waste water flowing out of the drain pipe 8, the condenser 2 cannot evaporate all the water, and the excess water will fall down and be temporarily collected in the second water collecting cavity 32.

[0054] On the other hand, the air blower is located behind the condenser. When the air blower works, the air first passes through the ice-cold evaporator, so that the air becomes a low-temperature airflow. The low-temperature airflow then passes through the warm condenser, which has a cooling effect on the condenser. The low-temperature cold air has a better air cooling effect. As shown in FIG. 6, the arrow direction is the airflow direction of the air blower. Figure 7

[0055] ​Further, in order to utilize the excess water collected in the second water collecting cavity 32, the preferred embodiment of the present application further comprises a water splashing mechanism 10 installed on the water collecting tray 3, one end of the water splashing mechanism 10 extends into the second water collecting cavity 32 to rotate, the operation of the water splashing mechanism 10 can splash water upward, thus the water splashing mechanism 10 can splash the water in the second water collecting cavity 32 onto the condenser 2, so that the water re- adheres to the fins of the condenser 2 to be evaporated again by heat absorption.

[0056] Specifically, referring to the accompanying drawings Figure 6 The water splashing mechanism 10 comprises a water splashing motor 101 and a water splashing wheel 102, the water collecting tray 3 is provided with an installation boss 33 on the outer side, the water splashing motor 101 is fixedly connected to the installation boss 33 by bolts, and the water splashing motor 101 is located on the outer side of the water collecting tray 3. The water collecting tray 3 is further provided with an installation gap 34 on the side wall surface, the output shaft of the water splashing motor 101 extends into the second water collecting cavity 32 through the installation gap 34, and the water splashing wheel 102 is located in the second water collecting cavity 32 and is fixedly installed on the output shaft of the water splashing motor 101, so that the water splashing wheel 102 rotates in the vertical plane, the water splashing motor 101 is drivingly connected to the water splashing wheel 102, and the structure is more convenient for disassembly and assembly of the water splashing mechanism 10.

[0057] When the second water collecting cavity 32 accumulates water to a certain depth, a part of the water splashing wheel 102 is located below the water surface, when the water splashing wheel 102 rotates at high speed, the water splashing wheel 102 will take water out of the water surface, and then the water splashes in the tangential direction of the rotation track of the water splashing wheel 102, and the general direction of the splashed water is upward.

[0058] Of course, in order to make the water splashed by the water splashing wheel 102 more evenly distributed on the condenser 2, in a preferred embodiment of the present application, the water splashing wheel 102 is arranged close to one side of the condenser 2, and the water splashed by the water splashing wheel 102 splashes to the other side of the condenser 2. For example, the water splashing wheel 102 is arranged close to the left side of the condenser 2, and the water splashed by the water splashing wheel 102 splashes to the right side of the condenser 2.

[0059] Further, the water splashing wheel 102 is arranged with a plurality of inclined teeth 1021 in the circumferential direction. The arrangement of the inclined teeth 1021 can make gaps between the teeth, and because water has tension, when the water splashing wheel 102 rotates out of the water surface, the water splashing wheel 102 will take out more water, that is, more water will be left in the gaps between the teeth, and the water will be separated from the water splashing wheel 102 due to the centrifugal force, and then splashes in the tangential direction of the water splashing wheel 102. This arrangement can make the water splashing efficiency of the water splashing wheel 102 higher. The inclined direction of the inclined teeth 1021 is opposite to the turning direction of the water splashing wheel 102, which can guide the water left in the gaps between the teeth to separate from the gaps more conveniently.

[0060] Further, as shown in the accompanying drawings Figure 4 and 5 The first water collecting cavity 31 and the second water collecting cavity 32 are provided with a partition plate 35, which is used to block the first water collecting cavity 31 and the second water collecting cavity 32, so as to reduce the possibility of the sewage in the second water collecting cavity 32 flowing into the first water collecting cavity 31. The second water collecting cavity 32 is provided with an inclined platform 36, which is inclined to the first water collecting cavity 31, and the side of the inclined platform 36 away from the first water collecting cavity 31 is higher than the side of the inclined platform 36 close to the first water collecting cavity 31, and the side of the inclined platform 36 close to the first water collecting cavity 31 is also lower than the partition plate 35, so that the water falling from the condenser 2 first drips on the inclined platform 36, and then slides along the inclined platform 36 into the second water collecting cavity 32, and the effect of the inclined platform 36 is to reduce the splashing effect caused by the water droplets colliding on the inclined platform 36, and reduce the possibility of the sewage entering the first water collecting cavity.

[0061] In order to further utilize the excess sewage in the second water collecting cavity 32, as shown in the accompanying drawings Figure 1 In this embodiment, the air water generator further comprises a compressor 11, and the top of the compressor 11 is provided with an evaporation cover 111 in an open-top structure, and the water collecting disc 3 is further provided with a water inlet 37 connected to the second water collecting cavity 32, and the water inlet 37 is located above the evaporation cover 111, so that the sewage collected in the second water collecting cavity 32 can fall into the evaporation cover 111 above the compressor 11, and since the compressor 11 generates a large amount of heat during operation, the water in the evaporation cover 111 absorbs the heat emitted by the compressor 11 and evaporates, thereby achieving the heat dissipation effect of the compressor 11.

[0062] The air water generator according to the present application should also contain other parts that should be possessed by existing air water generators, such as a shell, a water storage tank for purifying water, a drinking water outlet mechanism, etc.

[0063] Obviously, the above-described embodiments are only some embodiments of the present application, not all embodiments, and the preferred embodiments of the present application are given in the accompanying drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing specific embodiments, or equivalently replace some technical features therein. Any equivalent structure made by using the content of the present application specification and drawings, directly or indirectly applied to other related technical fields, is also within the patent protection scope of the present application.
