Description

Technical Field

[0001] The invention relates to the technical field of air coolers, in particular to an air cooler with self-cleaning function. Background Art

[0002] In addition to bringing fresh air and lowering the temperature in corporate workshops, public places, and commercial entertainment venues, the air cooler has another important feature: energy saving and environmental protection! It is a brand-new environmentally friendly product without compressors, refrigerants, or copper tubes. The main components are: evaporative wet curtains (multi-layer corrugated fiber laminates) and a 1.1KW main motor / 1 / 8 of the power consumption of traditional central air conditioners, which can save electricity for various industries. Therefore, it is widely used in homes. When the fan is running, it enters the cavity to generate negative pressure, causing the air outside the machine to flow through the porous wet wet curtain surface, forcing the dry bulb temperature of the air passing through the curtain to drop to a wet bulb temperature close to the air outside the machine, that is, the dry bulb temperature at the outlet of the air cooler is 5-12℃ lower than the outdoor dry bulb temperature (up to 15℃ in dry and hot areas). The drier and hotter the air, the greater the temperature difference, and the better the cooling effect; at the same time, because the machine uses the principle of evaporative cooling, it has the dual functions of cooling and humidifying;

[0003] However, when the outside air is introduced into the cavity through the operation of the fan, the air can filter impurities in the air through the air inlet and the wet curtain to ensure that the discharged gas is fresher. However, the temperature difference between the outside air and the fan is large, which easily produces water droplets attached to the air inlet. For a long time, the dust in the outside air adheres to the water droplets on the air inlet, causing impurities to adhere and block, making cleaning cumbersome and inefficient.

[0004] Moreover, when the wet curtain is soaked with cold water, the cold water drips from the top, and the wet curtain is in a static state to receive the cold water, resulting in low wetting efficiency of the wet curtain, and then resulting in slow cooling effect. In view of this, we propose a cold air blower with self-cleaning function. Summary of the invention

[0005] The object of the present invention is to provide a self-cleaning air cooler to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides a self-cleaning air cooler, comprising an air cooler housing, both sides of the outer wall of the air cooler housing are provided with air inlets, and an air inlet grille assembly is provided inside the air inlet, wherein:

[0008] A wet curtain plate is elastically slidably arranged inside the frame structure, and the baffle plate is used to adjust the size of the inlet by rotating with the limit rotating rod and abutting against the surface of the wet curtain plate.

[0009] As a further improvement of the present technical solution, a fan is rotatably provided inside the cold air shell, the fan is connected via an output shaft of a driving motor fixed to the inner wall of the cold air shell, and an air outlet grille is provided on the outer wall of the cold air shell, and the wind force of the fan is directed toward the air outlet grille.

[0010] As a further improvement of the technical solution, a water storage cavity is formed at the bottom of the inner cavity of the cold air housing, and a circulation cavity is formed at the top of the inner cavity of the cold air housing, a delivery pipe is connected between the circulation cavity and the water storage cavity, the end of the delivery pipe is connected to the drainage end of the water pump, and the water inlet end of the water pump is connected to the bottom of the inner cavity of the water storage cavity;

[0011] The bottom of the inner cavity of the water storage cavity near both sides is provided with through holes, and the through holes are located directly above the wet curtain plate.

[0012] As a further improvement of the technical solution, a guide plate is provided near the center of the inner cavity of the circulation cavity, and the guide plate is in a structure that smoothly extends toward a plurality of through holes, the through holes are at the lowest point of the guide plate, and the connection point at the upper end of the delivery pipe is located at the highest point of the guide plate;

[0013] A hose is connected to the top of the wet curtain plate, and the hose is connected to one of the through holes.

[0014] As a further improvement of the present technical solution, the fitting adjustment control unit at least includes a slide plate sliding in the slide groove on the outer wall of the limiting rotating rod, a coil spring is fixedly connected between the surface of the slide plate and the end of the inner cavity of the slide groove, and a torsion spring is fixedly connected between the baffle and the slide plate, and the torsion spring is used to generate a rebound force to keep the baffle in a horizontal state.

[0015] As a further improvement of the technical solution, the coil springs in the outer wall sliding grooves of two adjacent limiting rotating rods are symmetrically arranged, and the coil springs are in a compressed state to drive the two adjacent baffles to fit and connect.

[0016] As a further improvement of the technical solution, an elastic member is provided between the frame structure and the wet curtain board, and screws are fixedly connected at both ends of the elastic member. The two ends of the screws are respectively threadedly connected to the surface of the frame structure and the outer wall of the wet curtain board, and slide when the wet curtain board is subjected to extrusion force.

[0017] As a further improvement of the technical solution, the baffle is fixedly connected to a side of the slide plate close to the adjusting rod, and the slide plate is provided with a rotating groove on its outer surface, the rotating groove has two symmetrical limit grooves in the transverse and longitudinal directions on its inner wall, the adjusting rod has slots in the transverse and longitudinal directions on its outer wall, and blocks are elastically slidable inside the slots;

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the self-cleaning air cooler, two adjacent baffles are closely stacked when in a horizontal state through the fitting adjustment control, so that the limit rotating rod drives the baffle to rotate, so that the surfaces of the two baffles rub and scrape against each other, which is conducive to scraping off the water droplets attached to the surface of the grille formed by multiple baffles, improving convenience and preventing the water droplets from absorbing dust in the air and affecting the air intake effect;

[0022] In addition, when the baffle is driven by the limit rotating rod to rotate toward the wet curtain plate, the end of the baffle presses against the wet curtain plate and makes it slide outward. As the baffle rotates away, the wet curtain plate is reset. During the sliding and resetting process of the wet curtain plate, the wet curtain plate can shake off the attached impurities under the action of inertia. At the same time, during the sliding process, the dripping cold water can contact the wet curtain plate more evenly, thereby improving the wetting effect.

[0023] 2. In the self-cleaning air cooler, the baffle is kept in a vertical state by overcoming the twisting force of the twisting spring. At the same time, the friction resistance formed by the rubber pads on the outer walls of the two baffles also overcomes the twisting force of the twisting spring, further ensuring that the baffle is in a vertical state and more stable, so that the two adjacent baffles are in a vertical state to close the air inlet, reducing the contact of external dust with the wet curtain when not in use, and prolonging the service life;

[0024] Moreover, when the baffle is in a vertical state, it rotates along with the limit rotating rod, and can scrape when the end of the baffle is in contact with the outer surface of the wet curtain plate, which is beneficial to further clean the impurities and water droplets on the outer wall of the wet curtain plate.

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0040] The main components of the air cooler are: evaporative wet curtain (multi-layer corrugated fiber laminate) and 1.1KW main motor. It consumes 1 / 8 of the power of traditional central air conditioners, which can save electricity for various industries. Therefore, it is widely used in households. When the fan is running, it enters the cavity to generate negative pressure, so that the air outside the machine flows through the porous wet curtain surface, forcing the dry bulb temperature of the air passing through the curtain to drop to a level close to the wet bulb temperature of the air outside the machine. That is, the dry bulb temperature at the outlet of the air cooler is 5-12℃ lower than the outdoor dry bulb temperature (up to 15℃ in dry and hot areas). The drier and hotter the air, the greater the temperature difference and the better the cooling effect. At the same time, because the machine uses the principle of evaporative cooling, it has the dual functions of cooling and humidifying. Please refer to Figure 1-Figure 10 As shown, this embodiment provides a self-cleaning air cooler, including an air cooler housing 100, both sides of the outer wall of the air cooler housing 100 are provided with air inlets 110, and the air inlet 110 is provided inside the air inlet grille assembly 200, wherein:

[0041] The air intake grille assembly 200 at least comprises a frame structure 201 embedded in the air intake port 110, wherein a plurality of limit rotating rods 210 are rotatably arranged at equal intervals inside the frame structure 201, a plurality of baffles 220 are equidistantly arranged on the outer wall of the limit rotating rod 210, and a fitting adjustment control 230 is arranged between the baffles 220 and the limit rotating rod 210, and the baffles 220 on two adjacent limit rotating rods 210 are staggered by the fitting adjustment control 230, and a rebound force is generated to make the two stacked and fitted;

[0042] A wet curtain plate 300 is elastically slidably disposed inside the frame structure 201 , and the baffle plate 220 is used to adjust the size of the inlet by rotating with the limit rotating rod 210 and abutting against the surface of the wet curtain plate 300 .

[0043] The present invention takes into account that when the outside air is introduced into the cavity through the operation of the fan, the air can pass through the air inlet 110 and the wet curtain to filter impurities in the air, ensuring that the discharged gas is fresher. However, the temperature difference between the outside air and the inside of the fan is large, and water droplets are easily attached to the air inlet 110. For a long time, the dust in the outside air adheres to the water droplets on the air inlet 110, causing impurities to adhere and block, making cleaning cumbersome and inefficient. Therefore, if Figure 1 As shown, by using the fitting adjustment control 230, two adjacent baffles 220 are closely fitted and stacked when they are in a horizontal state, so that the limit rotating rod 210 drives the baffle 220 to rotate, so that the surfaces of the two baffles 220 rub and scrape against each other, which is conducive to scraping off impurities attached to the surface of the grille formed by the multiple baffles 220, improving the convenience of cleaning impurities and avoiding long-term attachment that affects the air intake effect;

[0044] Furthermore, considering that when the wet curtain is soaked with cold water, cold water drips from the top, and the wet curtain is in a stationary state to receive the cold water, the wetting efficiency of the wet curtain is low, and thus the cooling effect is slow. When the baffle 220 is driven by the limit rotating rod 210 to rotate toward the wet curtain plate 300, the end of the baffle 220 abuts against the wet curtain plate 300 and makes it slide outward. After the baffle 220 rotates away, the wet curtain plate 300 is reset. During the sliding and resetting process of the wet curtain plate 300, the wet curtain plate 300 can shake off the attached impurities under the action of inertia, which is beneficial to reduce the attachment of impurities and increase the service life. At the same time, during the sliding process, the dripping cold water can contact the wet curtain plate 300 more evenly, thereby improving the wetting effect.

[0045] On the basis of the above, the specific structure is disclosed in detail:

[0046] First, when the air cooler is working, the outside air is introduced into the air cooler housing 100 through the air inlet 110, and then the air is processed and discharged, so as to achieve the dual functions of cooling and humidifying. Figure 2 As shown, a fan fan 120 is rotatably provided inside the cold air housing 100, and the fan fan 120 is connected via an output shaft of a driving motor 122 fixed to the inner wall of the cold air housing 100, and an air outlet grille 121 is provided on the outer wall of the cold air housing 100. The wind force of the fan fan 120 is directed toward the air outlet grille 121, and the fan fan 120 is driven to rotate by the output shaft of the driving motor 122, so that the outside air is introduced into the cold air housing 100 from the inside of the air inlet 110, and the air is passed through the cold water of the wet curtain plate 300 for heat exchange, and then the air is cooled and humidified and discharged from the air outlet grille 121, thereby meeting the basic functions of cooling and humidifying.

[0047] Specifically, in order to allow the wet curtain plate 300 to be cyclically wetted by cold water to achieve a better air cooling effect, a water storage chamber 140 is formed at the bottom of the inner cavity of the cold air housing 100, and a circulation chamber 130 is formed at the top of the inner cavity of the cold air housing 100. A delivery pipe 150 is provided between the circulation chamber 130 and the water storage chamber 140. The end of the delivery pipe 150 is connected to a drainage end of a water pump 151, and the water inlet end of the water pump 151 is connected to the bottom of the inner cavity of the water storage chamber 140.

[0048] Through holes 132 are provided at the bottom of the inner cavity near both sides of the water storage chamber 140, and the through holes 132 are located directly above the wet curtain plate 300. By providing a water delivery door on the outer wall of the water storage chamber 140, cold water is poured into the water storage chamber 140 from the water delivery door, introduced into the drainage end by the water inlet end of the water pump 151, and then transmitted to the circulation chamber 130 from the delivery pipe 150, so that the cold water flows into the surface of the wet curtain plate 300 from the through hole 132, so that the wet curtain plate 300 is soaked and then purifies the incoming air, and at the same time, the excess water falls into the water storage chamber 140 again, realizing the reciprocating delivery of water flow, and to ensure that the cold water is always discharged, a refrigerator can be installed at the bottom of the inner cavity of the water storage chamber 140 to cool the water in the water storage chamber 140 to ensure that the cold water is always used to exchange heat with the air. This is something that people in the field of technology can easily think of and will not be elaborated here.

[0049] At the same time, in the initial stage, the water flow in the circulation chamber 130 is small, resulting in that the cold water cannot accurately flow downward from the through hole 132. Therefore, a guide plate 131 is provided near the center of the inner cavity of the circulation chamber 130. The guide plate 131 is in a structure that smoothly extends toward the plurality of through holes 132. The through holes 132 are at the lowest point of the guide plate 131, and the connection point at the upper end of the delivery pipe 150 is located at the highest point of the guide plate 131. When the cold water enters the circulation chamber 130, it flows along the direction of the guide plate 131 to the inside of the through hole 132. Even if there is little water, it can be guaranteed to drip downward, and at the same time, the efficiency of water circulation is accelerated;

[0050] A hose 310 is provided at the top of the wet curtain plate 300, and the hose 310 is connected to one of the through holes 132, so that when cold water enters the multiple through holes 132, part of the water flows from the bottom of the through hole 132 and drips onto the outer wall of the wet curtain plate 300, and part of the water flows from the through hole 132 along the hose 310 into the wet curtain plate 300, thereby accelerating the wetting effect of the wet curtain plate 300 and improving the refrigeration efficiency;

[0051] Furthermore, the hose 310 is made of an elastic material that can be twisted at will to avoid affecting the sliding of the wet curtain plate 300 .

[0052] Furthermore, when two adjacent baffles 220 are in a horizontal state, they can be stacked closely together to meet the requirement that relative friction occurs between the two during rotation, thereby improving the scraping effect of impurities. Figure 5 and Figure 6 As shown, the fitting adjustment control unit 230 is further disclosed, and the fitting adjustment control unit 230 at least includes a slide plate 231 sliding in the slide groove of the outer wall of the limiting rotating rod 210, a coil spring 232 is fixedly connected between the surface of the slide plate 231 and the end of the inner cavity of the slide groove, and a torsion spring 2310 is fixedly connected between the baffle 220 and the slide plate 231, and the torsion spring 2310 is used to generate a rebound force to keep the baffle 220 in a horizontal state.

[0053] Specifically, the coil springs 232 in the outer wall grooves of two adjacent limiting rotating rods 210 are symmetrically arranged, and the coil springs 232 are in a compressed state to drive the two adjacent baffles 220 to fit together, and the elasticity of the torsion spring 2310 is used to make the baffle 220 horizontal. At the same time, under the rebound force of the compression of the coil spring 232, the two adjacent baffles 220 generate a force to fit each other, ensuring that the two baffles 220 can contact each other and scrape impurities when rotating.

[0054] Furthermore, when the end of the baffle plate 220 slides against the wet curtain plate 300 during the rotation process, the end of the baffle plate 220 can be separated from the end of the wet curtain plate 300 for reset, such as Figure 7 As shown, an elastic member 320 is provided between the frame structure 201 and the wet curtain plate 300, and screws 321 are fixedly connected at both ends of the elastic member 320. The ends of the two screws 321 are respectively threadedly connected to the surface of the frame structure 201 and the outer wall of the wet curtain plate 300. When the wet curtain plate 300 is subjected to an extrusion force, it slides and is stretched by the elastic member 320. When the end of the baffle 220 leaves the surface of the wet curtain plate 300, the wet curtain plate 300 is reset under the elastic force of the stretching of the elastic member 320, which satisfies the movement of the wet curtain plate 300, is conducive to shaking off impurities, and reduces the occurrence of circulation inconvenience caused by blockage. Example 2

[0055] When the air cooler is not in use, the wet curtain plate 300 is exposed to the air. If the outside air flows quickly, it is easy to carry impurities to contact the wet curtain plate 300 and cause blockage. If such impurities are not handled for a long time, they are easy to adhere to the surface of the wet curtain plate 300 and cannot be shaken off due to the movement of the wet curtain plate 300. Therefore, if Figure 4 , Figure 8-Figure 10 As shown, the difference between this embodiment and embodiment 1 is that:

[0056] An adjusting rotating rod 233 is fixedly connected to one side of the baffle 220 close to the slide plate 231, and a rotating groove 2311 is provided on the outer surface of the slide plate 231, and two symmetrical limiting grooves 2312 are provided in the inner wall of the rotating groove 2311 in the horizontal and vertical directions, and a slot 2331 is provided in the outer wall of the adjusting rotating rod 233 in the horizontal and vertical directions, and a clamping block 2332 is elastically slidably provided inside the slot 2331;

[0057] The clamping block 2332 has a tendency to move outward and is adapted to be clamped inside the limiting groove 2312 .

[0058] Then, rubber pads 221 are provided on the outer walls of the baffles 220. The rubber pads 221 are used to increase the friction resistance of the outer walls of two adjacent baffles 220 when they are in a vertical state.

[0059] By rotating the baffle plate 220, it is switched from the horizontal state to the vertical state, so that the outer walls of the two adjacent baffle plates 220 are fitted together, and the extrusion force drives the card block 2332 to shrink and slide out from the horizontal limit groove 2312 and enter the inner part of the slot 2331. As the baffle plate 220 is rotated to the vertical state, the vertical limit groove 2312 is elastically extended into the limit groove 2312 for card connection and adaptation, overcoming the twisting force of the torsion spring 2310, ensuring that the baffle plate 220 is in the vertical state. At the same time, the friction resistance formed by the rubber pads 221 on the outer walls of the two baffle plates 220 also overcomes the twisting force of the torsion spring 2310, further ensuring that the baffle plate 220 is more stable in the vertical state, so that the two adjacent baffle plates 220 are in the vertical state to close the air inlet 110, reduce the contact of external dust with the wet curtain plate 300 when not in use, and improve the service life. At the same time, under the resilience of the compression of the coil spring 232, the outer walls of the two baffle plates 220 are tightly fitted to improve the sealing;

[0060] Moreover, when the baffle 220 is in a vertical state, it can rotate together with the limiting rotating rod 210, so that scraping can be performed when the end of the baffle 220 is in contact with the outer surface of the wet curtain plate 300, which is beneficial to further clean the impurities on the outer wall of the wet curtain plate 300. At the same time, during the scraping process, the wet curtain plate 300 is further disturbed, thereby further improving the efficiency of cold water wetting.

[0061] As for the rotation of the limit rotating rod 210, it is involved in both Example 1 and Example 2, and its rotation can be achieved by manual rotation or by connecting its end with the help of a motor output shaft. Any method that can control the rotation of the limit rotating rod 210 is applicable, which is conducive to arbitrarily rotating the angle of the limit rotating rod 210, thereby completing the above-mentioned required functions. This is easily associated with personnel in this technical field and will not be elaborated here.

[0062] 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 by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
