Description

Technical Field

[0001] The present invention relates to the technical field of air coolers, and particularly to a dual heat dissipation structure for an air cooler. Background Art

[0002] An air cooler is provided with a wet curtain and a fan. A water pump transports the water in the water tank to the wet curtain to keep the wet curtain moist. When hot air flows through the wet curtain, water evaporates and absorbs heat, reducing the air temperature and achieving the first heat dissipation. At the same time, the fan operates to blow out the cold air cooled by the wet curtain, forming an air-cooling effect and achieving the second heat dissipation. The cold air is sent to the area that needs to be cooled. Utilizing the natural physical phenomenon of water evaporation absorbing heat can effectively reduce the air temperature, and the evaporation of water can increase the air humidity, which is applicable to dry areas. Air cooling can quickly spread the cold air, making the cooling range wider and the effect more uniform. To ensure that the wet curtain of the air cooler can work continuously and effectively, it is crucial to clean or replace it regularly, because the water absorption and air permeability of the wet curtain have a direct impact on the performance of the air cooler. If the wet curtain is not properly cleaned for a long time, its surface may become a breeding ground for bacteria and molds, which will not only produce unpleasant odors but also seriously damage the indoor air quality. In addition, the cooling effect of the wet curtain will be greatly reduced. After a period of use, it may be damaged or deformed.

[0003] The Chinese patent document publication number: "CN112781132B discloses a dual heat dissipation structure for an air cooler and an air cooler. Among them, the dual heat dissipation structure of the air cooler includes a first heat dissipation body, a heat generation body, a heat exhaust body, and a second heat dissipation body. An accommodation cavity for storing a heat dissipation medium is provided inside the first heat dissipation body; at least part of the heat generation body is in contact with the heat dissipation medium; a gas collection cavity is provided between the heat exhaust body and the first heat dissipation body, and the heat exhaust body is also provided with a heat exhaust hole communicating with the gas collection cavity; the second heat dissipation body is located between the heat exhaust body and the first heat dissipation body.

[0025] Embodiment 1: Please refer to Figure 1 - Figure 11, A dual heat dissipation structure of a cold air blower, comprising: a water tank 1 and a housing 2 fixed on the water tank 1, further comprising: an axial flow fan 3 fixed inside the housing 2, and two wet curtains 4 are arranged inside the housing 2. A humidification unit 5 adapted to the two wet curtains 4 is arranged in the water tank 1. The humidification unit 5 is used to humidify the two wet curtains 4, and a cleaning unit 6 is arranged inside the housing 2. The cleaning unit 6 cleans and processes the two wet curtains 4, and; a filter element 7 is arranged inside the housing 2. The filter element 7 can filter dust and impurities in the air. A shaking mechanism 8 is arranged inside the housing 2. The shaking mechanism 8 is used to drive the wet curtain 4 to move up and down reciprocally. The bottom of the water tank 1 is provided with a chamfered slope to ensure that the water source is concentrated at the inner bottom position of the water tank 1, facilitating the replacement of the water source in the water tank 1; Wherein, a shutter 50 is fixed on the housing 2 by opening a groove. The shutter 50 is located on one side of the axial flow fan 3. A plurality of universal wheels 51 are fixed on the water tank 1. Through the setting of the shutter 50, by changing the angle of the shutter 50, the blown cold air swings up and down or left and right within a certain range, so as to realize air supply in different directions, expand the coverage range of the cold air, and can more evenly reduce the indoor temperature, enabling every corner of the room to feel cool. With the setting of the universal wheels 51, it is convenient for the user to push the device to move the position; In addition, a grille frame 47 is sleeved on the installation frame 31. A plurality of spring buckles 48 are fixed on the housing 2. The grille frame 47 is snap-connected with the spring buckles 48 through a snap sleeve 49. Through the cooperative setting of the spring buckles 48 and the snap sleeve 49, it is convenient for the user to disassemble the grille frame 47, so as to facilitate cleaning and maintenance after disassembling the grille frame 47; It should be noted that through the setting of the two wet curtains 4, the humidification unit 5 evenly sprays water on the water curtain, and under the action of gravity, it evenly flows on the surface of the water curtain to form a water film. When the external hot air passes through the water curtain, the water in the water film will absorb the heat in the air and evaporate, reducing the air temperature. Based on the principle that water absorbs heat of vaporization when evaporating, the air is cooled, and cold air is sent out. The cooled air is blown out by the axial flow fan 3 to form cold air, so as to achieve the purpose of reducing the indoor or local environment temperature. At the same time, the device can also increase the air humidity during operation and play a certain humidifying role; It also should be noted that the wet curtain 4 is generally made of special paper materials or fiber materials, with good water absorption and water permeability. There are many small pores on the surface of the wet curtain 4. When water is evenly distributed on the water curtain, a thin water film will be formed. When air passes through the wet curtain 4, the water evaporates and absorbs heat, thus reducing the air temperature. This is a conventional setting in this field, so it will not be elaborated in detail here.

[0026] Further, the humidifying unit 5 includes: a circulation water pump 9 is fixed in the water tank 1 through a bracket, the output end of the circulation water pump 9 is fixed with a connecting pipe 10, and the other end of the connecting pipe 10 is connected with at least two spray pipes 12 through a butt joint pipe 11. A water injection pipe 13 communicating with the inside is fixed on the water tank 1, and it is convenient to inject a fixed amount of water source into the water tank 1 through the water injection pipe 13; Wherein, a drain pipe 52 communicating with the inside is fixed at the bottom of the water tank 1, and the other end of the drain pipe 52 is fixed with a faucet 33. The water tank 1 is fixed to the drain pipe 52 through a support sleeve to prevent the drain pipe 52 from shaking; It should be noted that through the setting of the humidifying unit 5, it is responsible for transporting the water in the water tank 1 between the two wet curtains 4. When the axial flow fan 3 operates, the circulation water pump 9 pumps the water out of the water tank 1, pressurizes it and transports it to the position between the two wet curtains 4, so that the water can flow evenly on the surface of the wet curtain 4, which can effectively improve the wetting effect of the wet curtain 4 and the cooling effect of the cold air; It should also be noted that two spray pipes 12 are provided. The pressurized water is transported into the spray pipes 12 through the butt joint pipe 11, and the pressurized water is evenly sprayed on the opposite surfaces of the two wet curtains 4 through the spray pipes 12, so as to improve the wetting effect of the wet curtain 4.

[0027] In this solution, the cleaning and maintenance principle of the wet curtain 4 and the filter element 7: First of all, through the drive of the servo motor 22, the rotating shaft 23 rotates synchronously, driving the transmission wheel 24 to rotate synchronously. Using the transmission function of the connecting rod b25, the docking rod 20 and the mounting plate 15 move left and right reciprocally along the sliding groove 14 after being stressed, so as to use the mutually approaching mounting plates 15 to squeeze the wet curtain 4, so as to reduce the water retention capacity of the wet curtain 4 and take out the dust attached to the wet curtain 4 by the water flow; At the same time, using the meshing transmission function of the bevel gears 35, the transmission shaft 34 rotates synchronously, driving the cam 37 to rotate synchronously. Cooperating with the extrusion transmission function between the cam 37 and the extrusion plate 42, the filter element 7 is driven to vibrate up and down reciprocally, and the dust and impurities attached to the surface of the filter element 7 can be shaken off; Secondly, in cooperation with the water guide plate 27, the sewage containing impurities is guided to the seepage tank 29, so as to ensure that the sewage is guided into the water collecting box 30, and the water collecting box 30 realizes the centralized collection of the sewage.

[0028] Embodiment 2: Please refer to Figure 6 - Figure 9 This embodiment further illustrates the embodiment, and the difference lies in the cleaning method of the wet curtain 4.

[0029] Further, the cleaning unit 6 includes: several sliding grooves 14 are formed on the outer shell 2, an installation plate 15 is slidably connected to the sliding grooves 14, a wet curtain 4 is fixed on the installation plate 15, several guide rods 16 are fixed on the outer shell 2, and a hinge seat a 17 slidably penetrates through the guide rods 16, a hinge seat b 18 is fixed on the installation plate 15, a connecting rod a 19 is hinged between the hinge seat a 17 and the hinge seat b 18, two adjacent installation plates 15 are fixed by a docking rod 20, a support plate 21 is fixed on the outer shell 2, a servo motor 22 is fixed on the support plate 21, a rotating shaft 23 is coaxially fixed at one end of the output shaft of the servo motor 22, and a transmission wheel 24 is fixed on the rotating shaft 23, a connecting rod b 25 is hinged between the transmission wheel 24 and the docking rod 20, a recovery mechanism 26 is arranged in the water tank 1, and the recovery mechanism 26 is used for recovering the sewage squeezed from the wet curtain 4. An additional plate 46 is fixed on the installation plate 15, and the additional plate 46 is slidably connected to one side wall of the outer shell 2. Through the addition of the additional plate 46, it plays a role in guiding and limiting the movement of the installation plate 15, preventing the situation of shaking and instability when the installation plate 15 moves; Among them, the recovery mechanism 26 includes: two water guide plates 27 fixed in the water tank 1, a storage box 28 is fixed on the water tank 1, a seepage groove 29 is formed on the water tank 1 between the water guide plates 27 and the storage box 28, a water collecting box 30 slidably penetrates through the storage box 28, a handle is fixed on the water collecting box 30, and the water guide plates 27 and the inner wall of the water tank 1 are inclinedly distributed, so as to smoothly guide the sewage into the water collecting box 30; In addition, by the arrangement of the connecting rod a 19, it plays a role in supporting and guiding the installation plate 15, ensuring that the installation plate 15 is in a relatively stable state during the translational movement in the left - right direction, preventing the situation of displacement when the installation plate 15 moves. Cooperating with the sliding of the hinge seat a 17 on the guide rod 16, it plays a guiding role for the hinge seat a 17, and then improves the stability of the hinge seat a 17 during movement; It should be noted that through the setting of the cleaning unit 6, the problem that the wet curtain 4 is prone to mildew and peculiar smell due to being in a water - retaining state for a long time can be effectively solved. By adopting the method of squeezing the wet curtain 4, not only can the water - retaining amount of the wet curtain 4 be effectively reduced, but also the dust on the surface of the wet curtain 4 can be removed to a certain extent under the action of water flow during squeezing, and then the service life of the wet curtain 4 can be further improved; It should also be noted that through the configuration of the recovery mechanism 26, the sewage generated during the squeezing of the wet curtain 4 can be effectively collected and guided, and recovered into the water collecting box 30. This process not only ensures that the sewage does not flow into the water tank 1 and mix with the clean water, thus avoiding water quality pollution, but also realizes the centralized collection of sewage. In this way, users can conveniently dispose of the sewage in the water collecting box 30 regularly.

[0030] Embodiment Three: Please refer to Figure 9 -Figure 11 This embodiment further elaborates on other embodiments. The difference lies in the way of cleaning the filter element 7 by jolting it up and down.

[0031] Specifically, the jolting mechanism 8 includes: an installation frame 31 fixed on the outer shell 2. The inner side wall of the installation frame 31 is slidably connected with a frame 32, and the filter element 7 is installed in the frame 32. A transmission shaft 34 is rotatably connected to the support plate 21 through a rotating seat. The transmission shaft 34 and the rotating shaft 23 are meshed and driven through two bevel gears 35. A through groove 36 is formed in the installation frame 31, and a cam 37 located inside the through groove 36 is fixed on the transmission shaft 34. A positioning plate 38 is slidably connected in the installation frame 31. At least two connecting rods 39 that penetrate through the installation frame 31 are fixed on the positioning plate 38. One end of the connecting rod 39 is fixed with a connecting ring 40, and a spring 41 is sleeved on the surface of the connecting rod 39. One end of the spring 41 is fixed to the connecting ring 40, and the other end of the spring 41 is fixed to the installation frame 31. An extrusion plate 42 is fixed on the positioning plate 38, and the extrusion plate 42 abuts against the cam 37. Among them, a pressing plate 43 is rotatably connected to the outer shell 2 through a rotating rod. A positioning bolt 44 is fixed on the outer shell 2. A positioning groove 45 is formed in the pressing plate 43, and the positioning groove 45 is engaged with the positioning groove 45, and the pressing plate 43 abuts against the frame 32. It should be noted that by linking the jolting mechanism 8 with the cleaning unit 6, when squeezing and cleaning the wet curtain 4, the filter element 7 can be synchronously driven to move up and down reciprocally, so that the dust and impurities adsorbed on the surface of the filter element 7 can be shaken off, and then the purpose of cleaning the dust attached to the filter element 7 can be achieved, preventing the situation that the filter element 7 is severely blocked by dust after long-term use and affecting the use. The principle of the jolting mechanism 8 driving the filter element 7 to move up and down reciprocally: Through the drive of the servo motor 22, the rotating shaft 23 rotates synchronously. By the meshing and driving action of the two bevel gears 35, the transmission shaft 34 rotates synchronously, thereby driving the cam 37 to rotate synchronously. By the elastic action of the spring 41, it is ensured that the extrusion plate 42 is always in contact with the cam 37. Through the extrusion drive between the cam 37 and the extrusion plate 42, the positioning plate 38, the frame 32 and the filter element 7 can be driven to move up and down reciprocally, so as to achieve the purpose of shaking off the attached dust.
