Drain Tray for Air Conditioner and Parking Air Conditioner

technical field

The invention belongs to the technical field of air conditioner manufacturing, and specifically provides a water receiving tray for an air conditioner and a parking air conditioner.

Background technique

In today's daily life, with the continuous development and progress of society, people's requirements for the quality of life are gradually improving. As a powerful household appliance, air conditioners are increasingly entering our daily life.

An air conditioner heat exchanger is a device used to achieve heat exchange between cold and hot fluids, also known as heat exchangers. Heat exchangers generally include condensers and evaporators. The evaporator is a type of heat exchanger that relies on the evaporation of refrigerant liquid in the evaporator, which needs to absorb heat from the cooled objects and evaporate into gas to cool the objects that need to be cooled. heater. The evaporator plays an important role in the air conditioner, and its performance has an important influence on the working efficiency of the air conditioner. When the air conditioner performs refrigeration or dehumidification work, the condensed water will flow downward along the direction of the evaporator fin itself. In the water receiving tray, the condensed water collects and flows out of the air conditioner along the left and right drain ports, while the left and right ends of the evaporator water receiving tray are fully open to ensure smooth drainage. However, in the actual use process, the cooling capacity of the air conditioner will decrease. After investigation, the reason is that there is air between the left and right ends of the water receiving tray of the evaporator, which takes away part of the heat exchange of the evaporator and affects the The overall cooling effect of the air conditioner.

Chinese patent CN211261221U discloses a water-receiving tray and a window-type air conditioner. In the embodiment of the present invention, the water-receiving tray specifically includes a main plate body, and the surface of the main plate body facing the evaporator is formed with a sealing structure. The technical solution of the utility model is to form a sealing structure on the surface of the water receiving pan including the main body facing the evaporator, and the sealing structure contacts the bottom of the evaporator to prevent airflow from passing between the bottom of the evaporator and the water receiving pan pass. Therefore, during the use of the window air conditioner, the airflow entering the window air conditioner is discharged after sufficient contact with the evaporator, which can greatly improve the heat exchange efficiency of the window air conditioner. In this solution, a sealing structure is set between the water receiving tray and the evaporator. Although the influence of external air on the heat exchange efficiency of the evaporator is alleviated to a certain extent, it does not fundamentally solve the opposite problem of the drainage and sealing of the water receiving tray. .

Therefore, there is a need in the art to propose a new water receiving tray for an air conditioner to solve the above problems.

SUMMARY OF THE INVENTION

In order to solve the above problems in the prior art, that is, in order to solve the problem that the water receiving tray of the air conditioner is not tightly sealed, the air enters the evaporator from the drain port of the water receiving tray, resulting in poor heat exchange effect of the evaporator and affecting the overall cooling effect of the air conditioner. The present invention provides a water receiving tray for an air conditioner. The air conditioner includes an evaporator. A drainage groove is arranged on the upper part, the water-permeable member cover is arranged on the upper opening of the drainage groove, and the evaporator is arranged on the upper part of the water-permeable member;

The permeable member is configured to allow condensed water produced by the evaporator to flow to the drain groove and to at least partially prevent air in the drain groove from flowing to the evaporator.

In the specific embodiment of the above-mentioned water receiving tray for an air conditioner, the drainage groove is provided with a drainage port, and the drainage port is provided with a tightening structure (not shown in the figure).

In the specific embodiment of the above-mentioned water receiving tray for an air conditioner, an inclined baffle is further provided on the inner side of the drainage groove.

In the specific embodiment of the above-mentioned water receiving tray for an air conditioner, a parallel shunt dislocation rib is also provided on the inner side of the drainage groove.

In the specific embodiment of the above-mentioned water receiving tray for an air conditioner, the drainage ports are provided at two places, and the drainage ports are respectively provided on both sides of the drainage groove.

In the specific embodiment of the above-mentioned water receiving tray for an air conditioner, the drainage groove is arranged in a structure with a high middle and low sides.

In the specific embodiment of the above-mentioned water receiving tray for an air conditioner, a valve is provided at the water outlet.

In the specific embodiment of the above-mentioned water receiving tray for an air conditioner, an elastic component is provided at the valve.

In the specific embodiment of the above-mentioned water receiving tray for an air conditioner, the elastic component is a spring, and the valve is set as a one-way opening and closing valve.

The present invention also provides a parking air conditioner, which includes the water receiving tray for the air conditioner according to any one of the above technical solutions.

In the above technical solution of the present invention, no condensed water is generated when the air conditioner starts to work, and there is no water in the permeable member and the drainage groove at this time. The drain of the structure, the drain of the tightened structure will hinder the external air to a certain extent, so that the air intake will be reduced, and then the external air will pass through the inclined baffle in the drainage groove, and the inclined baffle will change its movement direction, making it The phenomenon of blowing to the side wall of the drainage groove and blowing back, so that the wind speed of the external air entering the drainage groove is reduced, and then the external air will encounter parallel shunt dislocation ribs, and the air entering the water receiving tray will be divided at this time. It is divided into several parts to further reduce the wind speed. After a series of deceleration blocks, the air will enter the evaporator after being blocked by the permeable parts. At this time, the air entering the evaporator has been reduced layer by layer, and will not affect the evaporation. The heat exchange of the air conditioner has a great influence. After the air conditioner runs for a period of time, the condensed water gradually soaks the water-permeable parts and flows into the water receiving tray. When the air conditioner continues to run continuously, the permeable parts are completely soaked by the condensed water, and a liquid seal is formed between the evaporator and the water receiving tray, which completely isolates the passage of external air entering the evaporator. Therefore, the solution proposed by the present invention perfectly solves the problem that the water receiving tray of the air conditioner is not tightly sealed, and the air enters the evaporator from the drain port of the water receiving tray, resulting in the heat exchange of the evaporator. The effect is poor, which affects the overall cooling effect of the air conditioner.

As shown in Figures 1 and 2, the water receiving tray (1) for an air conditioner of the present invention comprises a water receiving tray body (11) and a water permeable member (12) (eg sponge), wherein the water receiving tray body (11) The water permeable member (12) is arranged above the main body (11) of the water receiving tray, and the air conditioner also includes an evaporator (2), the evaporator (2) is arranged above the water permeable member (12), and the evaporator (2) is closely connected with the water permeable member (12), and the water permeable member (12) should be set to a size that can cover the evaporator (2) in all directions, so that the evaporator (2) can be exchanged during the heat exchange process. The generated condensed water can be completely absorbed and discharged by the water permeable member (12), a drainage groove (111) is provided on the main body (11) of the water receiving tray, and the two side walls of the drainage groove (111) are slightly higher than the water receiving tray. The side wall of the main body (11) is convenient for the storage of a certain amount of water in the drainage groove (111). A drain port (1111) is provided, and the drain port (1111) is provided with a tightening structure.

In the case of using the above-mentioned embodiment, no condensed water is generated when the air conditioner starts to work, and there is no water in the water permeable member (12) and the drain groove (111) at this time, and the outside air flows from the drain (1) of the water receiving tray (1). 1111), and enter the drainage groove (111) through the tightening structure provided at the drain port (1111). Small, the air entering the water receiving tray (1) can only enter the evaporator (2) after being blocked by the water permeable member (12). At this time, the air entering the evaporator (2) has been reduced and will not It has a great influence on the heat exchange of the evaporator (2). After the air conditioner runs for a period of time, condensed water is gradually generated on the evaporator (2). As the condensed water gradually accumulates, the condensed water will begin to soak through. The water part (12) flows into the drainage groove (111) of the water receiving tray (1) along the permeable part (12), and then the condensed water in the drainage groove (111) flows to the drainage port (111) along the 1111), when the air conditioner continues to run for a period of time, the permeable part (12) is completely soaked by the condensed water, and the permeable part (12) filled with water is located between the evaporator (2) and the water receiving tray (1). A liquid seal is formed between the two, completely isolating the passage of air entering the evaporator (2), and at the same time, due to the water-permeable characteristics of the water-permeable member (12), the discharge of the condensed water will not be hindered.

It is a problem that affects the overall cooling effect of the air conditioner.

Regarding the water-permeable member (12), although the water-permeable member (12) exemplified in the above embodiment is a sponge, this is not the only choice for the water-permeable member (12). The water-permeable member (12) that is water-permeable and blocks the action of air, and, in order to realize the liquid seal between the evaporator (2) and the water-receiving tray (1), the material of the water-permeable member (12) should also meet the requirements of Certain water absorption capacity, such as products made of pure cotton materials.

In addition, regarding the size of the water permeable member (12), although the above mentioned water permeable member (12) should be able to cover the evaporator (2) from all directions, the size of the water permeable member (12) is not unlimited. Those skilled in , on the premise of meeting the sealing requirements for the evaporator (2), the size of the permeable member (12) should not exceed the size of the drainage groove (111) to prevent the condensed water in the permeable member (12) from flowing to the drainage groove (111). ) outside.

Regarding the heights of the two side walls of the drainage groove (111), those skilled in the art can understand that the selection of the heights of the side walls of the drainage groove (111) should satisfy at least two requirements. In the first aspect, the drainage groove (111) 111) The height of the side wall should meet the requirement of the maximum discharge volume of condensed water, so as to avoid the problem of untimely discharge of condensed water or even leakage of condensed water caused by the too small discharge of the drainage groove (111). On the other hand, as mentioned in the background art, in the process of discharging the condensed water from the water receiving tray (1), external air will be mixed into the evaporator (2), which will affect the heat exchange efficiency of the evaporator (2). Therefore, the height of the side wall of the drainage groove (111) should not be set too high to avoid causing more outside air to flow into the evaporator (2). Therefore, the height of the side wall of the drainage groove (111) should be It is set to reduce its height as much as possible on the premise of meeting the maximum discharge of condensate.

In the case of the above-mentioned embodiment, since the air outside the water receiving tray (1) enters the inside of the water receiving tray (1), it will advance along the drain groove (111) in the direction of the evaporator (2). Therefore, in order to be able to Effectively prevent external air from entering the evaporator (2), which will have a bad influence on the heat exchange efficiency of the evaporator (2). In this embodiment, multiple sets of inclined baffles (1112) are arranged in the drainage groove (111). , and the inclined baffle (1112) is arranged in a herringbone shape. When the outside air advances along the drain groove (111), the inclined baffle (1112) will change the airflow direction of the outside air entering the air conditioner. When the baffle (1112) is used, the inclined baffle (1112) will guide the air flow to the two side walls of the drainage groove (111). The strength of the external airflow entering the air conditioner can be weakened to a certain extent, and at the same time, certain gaps are left between the multiple groups of inclined baffles (1112), so that the condensed water can flow out of the drain groove (111) smoothly.

The advantage of the above embodiment is that, while ensuring that the condensed water of the evaporator (2) can be discharged smoothly, it also prevents a large amount of external air from being directly blown into the evaporator (2), which affects the heat exchange efficiency of the evaporator (2). At the same time, the above-mentioned embodiment has a simple structure and obvious effect, and can greatly improve the problem that the air leakage of the water receiving tray (1) affects the heat exchange efficiency of the evaporator (2).

In a preferred embodiment, parallel dislocation ribs (1113) are provided on the inner side of the drainage groove (111), and the parallel dislocation ribs (1113) may be arranged in multiple groups.

The advantage of the above-mentioned embodiment is that when the external air enters the drainage groove (111), it will be divided into several airflows by the parallel shunt dislocation ribs (1113). Air impact effect, thereby reducing the influence on the heat exchange efficiency of the evaporator (2).

In a preferred embodiment, the drainage ports (1111) on the drainage groove (111) are provided at two places, and they are respectively provided on both sides of the drainage groove (111).

The advantage of the above-mentioned embodiment is that the drain ports (1111) are provided on both sides to discharge the dripping condensate water from the drip tray (1) from two directions, which improves the drainage efficiency, and when the application object is a parking air conditioner During the use of the parking air conditioner, since the vehicle may be parked on a sloped road, in this case, setting the two-direction drain (1111) can ensure that no matter the vehicle is tilted forward or backward, the connection The water in the water pan (1) can be drained smoothly, so that the blockage and leakage of the condensed water will not be caused.

In a preferred embodiment, the drainage groove (111) is arranged in a structure with a high middle and low sides.

The advantage of the above embodiment is that by setting the drain groove (111) to be high in the middle and low on both sides, the draining of the condensate in the drain groove (111) can be accelerated, and the drainage efficiency of the water receiving tray (1) can be improved.

In a preferred embodiment, a valve (1114) is provided at the drain port (1111) of the drain groove (111).

In the case of adopting the above embodiment, during the operation of the air conditioner, since no condensation water is generated at the beginning of operation, the water permeable member (12) is not wetted by the condensation water, and the outside air can pass through the drainage groove (111) at this time. After passing through the water permeable member (12), it enters the evaporator (2). Therefore, a valve (1114) is set at the drain port (1111) of the drain tank (111). The valve (1114) isolates the entry of outside air. When the condensed water is gradually generated and saturated with the permeable part (12) with the operation of the air conditioner, the valve (1114) is opened to drain the water, although outside air can enter the connection. Inside the water pan (1), but since the water permeable member (12) has been soaked with water and formed a liquid seal for the evaporator (2) and the water receiving tray (1), the outside air cannot enter the evaporator through the water permeable member (12) (2) and affect the heat exchange efficiency of the evaporator (2).

The advantage of the above embodiment is that, by adding a valve (1114) at the water outlet (1111) of the water collecting tank, the heat exchange efficiency of the evaporator (2) caused by the outside air entering the evaporator (2) at the initial stage of operation of the air conditioner is solved At the same time, after the permeable member (12) is flooded with water, it is only necessary to open the valve (1114) to perform the drainage operation. This embodiment has a simple structure and convenient operation, and solves the problem of the water receiving tray (1) of the air conditioner. ) is not tightly sealed, and the air enters the evaporator (2) from the drain port (1111) of the water receiving tray (1), resulting in poor heat exchange effect of the evaporator (2) and affecting the overall cooling effect of the air conditioner.

In a preferred embodiment, a valve (1114) is provided at the drain port (1111) of the drain groove (111), and an elastic reset component is also provided at the valve (1114) (because the elastic reset component is a common structure, Therefore, it is not shown in the figure), and the elastic reset assembly is set to a state in which the valve (1114) can be rebounded closed in a default state.

In the case of adopting the above-mentioned embodiment, when the air conditioner just starts to operate, no condensation water is generated. At this time, due to the existence of the elastic reset component, the valve (1114) is in a closed state, and the entry of outside air is blocked. When the condensate is running, the gradually collected condensate flows to the drain (1111) through the drain groove (111). When the condensate accumulates to a certain amount, the momentum of the water flow will exceed the elastic force of the elastic component, so that the valve (1114) is opened and the condensation The water is discharged from the drain port (1111), and the water permeable member (12) has been completely soaked at this time, which can achieve subsequent blocking of the external air. When the condensed water does not need to be discharged, the elastic component will bounce the valve (1114) back To the closed state, the barrier to the outside air is realized.

The advantage of the above embodiment is that only one elastic component is provided at the valve (1114), the draining process of the water receiving tray (1) can be automatically completed, and there is no need to manually open the valve (1114) and close the valve (1114). At the same time, this embodiment can also ensure that no external air will enter the evaporator (2) during the whole process, which solves the problem that the water receiving tray (1) of the air conditioner is not tightly sealed, and the air from the water receiving tray (1) is not tightly sealed. The water outlet (1111) enters the evaporator (2), resulting in poor heat exchange effect of the evaporator (2), which affects the overall cooling effect of the air conditioner.

Regarding the above-mentioned elastic components, those skilled in the art can understand that the elastic components can be components with a rebound function common in the art, such as elastic diaphragms, bellows or spring tubes, etc. If necessary, in the art Those skilled in the art can modify the selection of the elastic components, and these common modifications do not exceed the inventive principle of the present invention, and therefore also fall within the protection scope of the present invention.

In a preferred embodiment, a valve (1114) is provided at the drain port (1111) of the drain groove (111), an elastic reset component is also provided at the valve (1114), and the valve (1114) is provided as a single To open and close the valve (1114).

Different from the above-mentioned common valve (1114) provided at the drain port (1111) of the drain groove (111), in this embodiment, the valve (1114) is set to only be able to follow the water flow in the drain groove (111). The direction of opening is outward but cannot be opened inward. In the case of using the above embodiment, when the air conditioner first starts to operate, no condensed water is generated in the drain groove (111). At this time, due to the existence of the elastic reset component, the valve (1114) ) is in the closed state, with the operation of the air conditioner, condensed water is gradually generated and merged into the drainage groove (111), the condensed water in the drainage groove (111) flows to the one-way opening and closing valve (1114) and overcomes the elasticity The elastic force of the reset component pushes the one-way on-off valve (1114) to open for drainage, and when the drainage is completed or does not need to be drained, the elastic component bounces the valve (1114) back to the closed state. In a special case , when the outside air is strong, the elastic reset assembly may not be enough to prevent outside air from entering the water receiving tray (1). Therefore, the valve (1114) is set as a one-way opening and closing valve (1114) at this time. Since the valve (1114) itself is only allowed to open to the outside of the water receiving tray (1) and not inward, it can completely prevent the outside air from entering the water receiving tray ( 1), thus ensuring the normal operation of the evaporator (2).

The advantage of the above embodiment is that the purpose of one-way output is achieved by arranging a one-way opening and closing valve (1114) and an elastic reset component at the drain port (1111) of the drain groove (111). The discharge of the condensed water in the pan (1) will not cause the outside air to enter the evaporator (2) to have a great influence on its heat exchange efficiency.

The present invention also provides a parking air conditioner, comprising the water receiving tray (1) for the air conditioner according to any one of the above technical solutions.

So far, the technical solutions of the present invention have been described with reference to the preferred embodiments shown in the accompanying drawings, however, those skilled in the art can easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
