Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to a water tray and an air conditioner. Background Technology

[0002] Currently, air conditioners primarily regulate indoor temperature through heat exchangers. The refrigerant absorbs heat from the air during evaporation within the heat exchanger, lowering the temperature of the heat exchanger and the surrounding air, thus achieving effective indoor cooling.

[0003] Because the surface temperature of the heat exchanger is lower than room temperature, when indoor air containing a certain level of humidity flows through the heat exchanger, the water vapor in the air will condense into condensate on the surface of the heat exchanger. Therefore, in related technologies, a drip tray is usually installed at the bottom of the heat exchanger to collect and drain the condensate.

[0004] However, the drainage channels inside the water collection tray are usually flat, resulting in low drainage efficiency and a tendency for water to accumulate. Utility Model Content

[0005] This application provides a water collection tray and an air conditioner to solve the problems of low drainage efficiency and easy water accumulation in the water collection tray.

[0006] On one hand, this application provides a water receiving tray for connection to a heat exchanger. The water receiving tray includes: a base with a water storage section; a first guide member disposed on one side of the base, the first guide member having a first inclined surface; a second guide member disposed on the other side of the base, the second guide member having a second inclined surface, and the first inclined surface and the second inclined surface being opposite to each other, the first inclined surface, the second inclined surface and the base forming a flow cavity, the flow cavity being connected to the water storage section; and a drain outlet disposed on the base and connected to the water storage section, so that the condensate discharged from the heat exchanger is discharged sequentially through the flow cavity, the water storage section and the drain outlet.

[0007] In the preferred embodiment of the above-mentioned water receiving tray, the water storage part includes a first water storage chamber and a second water storage chamber. The second water storage chamber is disposed in the first water storage chamber and has a stepped structure with the first water storage chamber. The drain outlet is connected to the second water storage chamber.

[0008] In the preferred embodiment of the above-mentioned water receiving tray, at least one of the first inclined surface and the second inclined surface is inclined downward in the direction toward the base, so that the flow cavity forms a structure that is wide at the top and narrow at the bottom.

[0009] In the preferred embodiment of the above-mentioned water receiving tray, the first inclined surface and the second inclined surface are inclined downward in the direction toward the drain outlet, so that the width of the flow cavity gradually decreases in the direction toward the drain outlet.

[0010] In the preferred embodiment of the above-mentioned water receiving tray, the side of the base connected to the first guide and the second guide is inclined downward in the direction toward the drain outlet.

[0011] In the preferred embodiment of the above-mentioned water receiving tray, the first guide has at least one connecting portion, which is used to connect to the heat exchanger.

[0012] In the preferred embodiment of the above-mentioned water receiving tray, the connecting part is a slot, which is used to engage with the heat exchanger.

[0013] In the preferred embodiment of the above-mentioned water receiving tray, a water-blocking component is also included, which is arranged around the periphery of the base.

[0014] In the preferred embodiment of the above-mentioned water receiving tray, a water storage groove is provided on the base. The water storage groove is located at the end of the flow cavity away from the drain outlet and is connected to the flow cavity.

[0015] On the other hand, embodiments of this application provide an air conditioner, including a fan, a heat exchanger, and a water collection tray as described in any of the first aspects, wherein the fan is connected to the heat exchanger, and the water collection tray is disposed below the heat exchanger to collect the condensate discharged from the heat exchanger.

[0016] Those skilled in the art will understand that the water receiving tray and air conditioner provided in this application embodiment are used to connect to a heat exchanger. The water receiving tray includes a base and a first guide member and a second guide member disposed on the base. The first guide member has a first inclined surface, and the second guide member has a second inclined surface. A flow cavity is formed between the first inclined surface, the second inclined surface, and the base. Through the guidance of the first inclined surface and the second inclined surface, it is convenient to collect condensate, increase the flow velocity of condensate in the flow cavity, and thus improve drainage efficiency.

[0017] Meanwhile, the base is equipped with a water storage section and a drain outlet. Condensate flows from the flow chamber to the water storage section and then is discharged through the drain outlet, thus avoiding the problem of condensate remaining in the entire flow chamber when the flow of condensate is not smooth.

Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the water tray of this utility model is described in conjunction with an air conditioner, this is not limiting; other devices with condensate water receiving requirements can also be configured with the water tray of this utility model.

Therefore, it should not be construed as a limitation of this utility model.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] An air conditioner indoor unit typically consists of a casing, a heat exchanger housed within the casing, and a fan. The heat exchanger lowers the temperature of the surrounding air by evaporating the refrigerant from a liquid to a gaseous state under low pressure. The fan, with its rotating blades, generates airflow, drawing in hot indoor air and guiding it across the surface of the heat exchanger. This allows for thorough heat exchange between the air and the refrigerant; the refrigerant absorbs the heat, and the air is cooled. The cooled air is then blown out of the indoor unit and distributed into the room through the unit's air outlet, thus completing the cooling process.

[0028] The preferred technical solution of the water receiving tray of this utility model is described below in conjunction with the above-mentioned air conditioner.

[0029] Reference Figures 1 to 4 During the cooling process of an air conditioner, the surface temperature of the heat exchanger 10 is lower than the dew point temperature of the indoor air, which is the temperature at which water vapor in the air turns into dew. When water vapor in the indoor air comes into contact with the cooler surface of the heat exchanger 10, the water vapor condenses into liquid water, i.e., condensate. This condensate drips directly into the interior of the air conditioner or the surrounding environment, causing problems such as equipment damage, short circuits, or corrosion. Therefore, this invention provides a drip tray connected to the heat exchanger 10 to receive the condensate discharged from the heat exchanger 10.

[0030] The water receiving tray provided by this utility model includes a base 100, on which a water storage part 110 is provided; a first guide 200 is provided on one side of the base 100, and the first guide 200 has a first inclined surface 210; a second guide 300 is provided on the other side of the base 100, and the second guide 300 has a second inclined surface 310, and the first inclined surface 210 and the second inclined surface 310 are arranged opposite to each other, the first inclined surface 210, the second inclined surface 310 and the base 100 surround to form a flow cavity 400, and the flow cavity 400 is connected to the water storage part 110; and a drain outlet 500 is provided on the base 100 and is connected to the water storage part 110, so that the condensate discharged from the heat exchanger 10 is discharged sequentially through the flow cavity 400, the water storage part 110 and the drain outlet 500.

[0031] In the above embodiment, the base 100 is used to receive the condensate discharged from the heat exchanger 10. The first guide 200 and the second guide 300 are respectively disposed on opposite sides of the base 100. The first guide 200 has a first inclined surface 210, and the second guide 300 has a second inclined surface 310. Together with the base 100, they form a flow cavity 400, so that the condensate discharged from the heat exchanger 10 can flow through the flow cavity 400 to the water storage section 110 and then be discharged through the drain outlet 500.

[0032] The flow chamber 400 is matched with the air duct of the fan 20, so that the condensate can flow under the blowing of the fan 20.

[0033] In the above embodiment, the water storage section 110 is a water storage tank formed on the base 100, and the drain outlet 500 is a through hole formed on the base 100 and connected to the water storage tank. When the amount of condensate is small, the condensate will directly pass through the water storage section 110 and be discharged through the drain outlet 500. When the amount of condensate is large, the water storage tank acts as a buffer, causing the condensate to accumulate in the water storage tank and then be discharged through the drain outlet 500. This avoids the problem of condensate accumulating in the flow chamber 400 when the amount of condensate is large, and the water storage tank acts as a buffer to prevent condensate from overflowing.

[0034] Meanwhile, by setting up a water storage section 110, condensate can be temporarily stored in the water storage section 110, thereby avoiding the accumulation of condensate in the entire flow chamber 400 and reducing the water storage area.

[0035] In the above embodiment, the first guide 200 and the second guide 300 are disposed on the base 100 to guide the flow direction of condensate. The first guide 200 has a first inclined surface 210, and the second guide 300 has a second inclined surface 310. The first inclined surface 210 and the second inclined surface 310 are arranged opposite to each other. When condensate drips onto the first inclined surface 210 or the second inclined surface 310, it can flow along the inclined direction of the first inclined surface 210 or the second inclined surface 310 to the base 100, thereby improving the smoothness of condensate flow and increasing drainage efficiency.

[0036] In the above embodiments, the first guide 200 and the second guide 300 can be manufactured with the base 100 using an integral molding process, or they can be manufactured separately and then assembled. This embodiment does not impose any restrictions on this.

[0037] In one optional embodiment, the water storage unit 110 includes a first water storage chamber 111 and a second water storage chamber 112. The second water storage chamber 112 is disposed inside the first water storage chamber 111 and has a stepped structure with the first water storage chamber 111. The drain outlet 500 is connected to the second water storage chamber 112.

[0038] In the above embodiment, the water storage unit 110 includes a first water storage chamber 111 and a second water storage chamber 112 arranged in a stepped manner, so that the first water storage chamber 111 and the second water storage chamber 112 can store water together. When the amount of condensate is small, the condensate passes through the flow chamber 400, the first water storage chamber 111 and the second water storage chamber 112 in sequence, and is discharged through the drain outlet 500. As the amount of water increases, the condensate will gradually be discharged through the drain outlet 500, ensuring that the water storage unit 110 will not be overloaded. However, if the condensate generation rate is too fast or the drainage capacity of the drain outlet 500 is insufficient to cope with the current amount of condensate, the second water storage chamber 112 may fill up quickly. Once the second water storage chamber 112 reaches its capacity limit and cannot store more condensate, the condensate will overflow from the second water storage chamber 112 and temporarily accumulate in the first water storage chamber 111. Thus, the arrangement of the first water storage chamber 111 and the second water storage chamber 112 provides additional water storage space to cope with the sudden increase in the amount of condensate and ensure the smooth discharge of condensate.

[0039] In one alternative embodiment, at least one of the first inclined surface 210 and the second inclined surface 310 is inclined downward in the direction toward the base 100, so that the flow cavity 400 forms a structure that is wide at the top and narrow at the bottom.

[0040] In the above embodiment, the first inclined surface 210 may be inclined downward in the direction toward the base 100 so that the flow cavity 400 forms a structure that is wide at the top and narrow at the bottom. The second inclined surface 310 may also be inclined downward in the direction toward the base 100 so that the flow cavity 400 forms a structure that is wide at the top and narrow at the bottom, thereby increasing the flow velocity of condensate dripping onto the first inclined surface 210 or the second inclined surface 310.

[0041] In an optional embodiment, both the first inclined surface 210 and the second inclined surface 310 are inclined downward in the direction toward the base 100, and their inclination angles may be the same or different.

[0042] In the above embodiment, the flow cavity 400 forms an inverted trapezoidal structure that is wide at the top and narrow at the bottom, which makes it easier for condensate to flow along the inclined direction of the first inclined surface 210 and the second inclined surface 310, and smoothly flow to the base 100 and be discharged through the drain outlet 500. This optimizes the flow path of the condensate, ensures that the water can leave the inclined surface quickly, and improves the drainage efficiency.

[0043] The specific tilt angles of the first inclined plane 210 and the second inclined plane 310 can be adaptively selected according to actual needs.

[0044] In one alternative embodiment, the first inclined surface 210 and the second inclined surface 310 are inclined downward in the direction toward the drain outlet 500, so that the width of the flow cavity 400 gradually decreases in the direction toward the drain outlet 500.

[0045] In the above embodiment, the end of the flow cavity 400 away from the drain outlet 500 gradually narrows towards the end closer to the drain outlet 500, thereby gradually reducing the cross-sectional area of ​​the flow cavity 400, increasing the flow velocity of the condensate in the flow cavity 400, reducing the residence time of the condensate in the flow cavity 400, and enabling the condensate to flow to the drain outlet 500 more quickly, thus improving the drainage efficiency.

[0046] The specific tilt angles of the first inclined plane 210 and the second inclined plane 310 can be adaptively selected according to actual needs.

[0047] In one alternative embodiment, the side of the base 100 connected to the first guide 200 and the second guide 300 is inclined downward in the direction toward the drain outlet 500.

[0048] In the above embodiment, the side of the base 100 connected to the first guide 200 and the second guide 300 is inclined downwards in the direction towards the drain outlet 500, thereby providing guidance for the condensate and ensuring that the condensate can flow naturally and smoothly. At the same time, it can also accelerate the flow rate of the condensate and improve drainage efficiency.

[0049] The specific tilt angle can be adaptively selected according to actual needs.

[0050] In one alternative embodiment, the first guide 200 has at least one connecting portion 220 for connection to the heat exchanger 10.

[0051] In the above embodiment, the first guide 200 is connected to the heat exchanger 10 via the connecting part 220 to fix the water receiving tray below the heat exchanger 10 to receive condensate.

[0052] The number of connecting parts 220 can be multiple, and the multiple connecting parts 220 are evenly and spaced on the first guide member 200 to ensure the stability of the water receiving tray and the heat exchanger 10.

[0053] In one optional embodiment, there are two connecting portions 220, which are located at opposite ends of the first guide 200.

[0054] In an alternative embodiment, a connecting portion 220 may also be provided on the base 100 and the second guide 300 to further enhance the stability of the fixation between the water receiving tray and the heat exchanger 10.

[0055] The connecting part 220 can be a snap fastener, bolt, or other structure that can achieve fixation, and can be selected adaptively according to actual needs.

[0056] In one alternative embodiment, the connecting part 220 is a slot for engaging with the heat exchanger 10.

[0057] In the above embodiment, the connecting part 220 is a slot, and the bottom of the heat exchanger 10 can be inserted into the slot and engaged with the slot to fix the water receiving tray.

[0058] By adopting the above-described implementation method, the slot can be detachably fixed, which makes it easy for operators to disassemble and install the water tray and to clean the water tray regularly to prevent impurities or dust from entering the water tray and affecting the flow of condensate.

[0059] In one alternative embodiment, the water receiving tray further includes a water-blocking member 600, which surrounds the periphery of the base 100.

[0060] In the above embodiment, a water-blocking member 600 is also provided on the base 100. The water-blocking member 600 surrounds the periphery of the base 100 and confines the first guide member 200 and the second guide member 300 within the area surrounded by the water-blocking member 600. When the water receiving tray is installed below the heat exchanger 10, the water-blocking member 600 abuts against the bottom of the heat exchanger 10, thereby preventing condensate from overflowing from the base 100 under the blowing of the fan 20.

[0061] The water baffle 600 may also be equipped with a sealing element to ensure the airtightness of the connection between the water receiving tray and the heat exchanger 10.

[0062] In one optional embodiment, a water storage groove 120 is provided on the base 100. The water storage groove 120 is located at the end of the flow cavity 400 away from the drain outlet 500 and is connected to the flow cavity 400.

[0063] In the above embodiment, when the water receiving tray is installed on the heat exchanger 10, to ensure sealing during installation, the bottom of the end plate of the heat exchanger 10 is usually placed against the base 100, which affects the outflow of condensate from the bottom of the end plate of the heat exchanger 10. Therefore, a water storage groove 120 is provided on the base 100, which is matched with the bottom of the end plate of the heat exchanger 10, so that the condensate flowing out from the bottom of the end plate of the heat exchanger 10 can first flow into the water storage groove 120, and then flow through the flow cavity 400 to the drain outlet 500 for discharge.

[0064] On the other hand, the present invention also provides an air conditioner, including a fan 20, a heat exchanger 10 and a water collection tray as described in any of the above embodiments. The fan 20 is connected to the heat exchanger 10, and the water collection tray is disposed below the heat exchanger 10 to collect the condensate discharged from the heat exchanger 10.

[0065] The specific structure of the water receiving tray has been described in the above embodiments and will not be repeated here.

[0066] The air conditioner provided by this utility model has a water collection tray placed below the heat exchanger 10 to collect the condensate discharged from the heat exchanger 10. The water collection tray includes a base 100 and a first guide 200 and a second guide 300 disposed on the base 100. The first guide 200 has a first inclined surface 210, and the second guide 300 has a second inclined surface 310. A flow cavity 400 is formed between the first inclined surface 210, the second inclined surface 310 and the base 100. The condensate is easily collected by the guidance of the first inclined surface 210 and the second inclined surface 310, which increases the speed at which the condensate flows from the first inclined surface 210 or the second inclined surface 310 to the base 100, thereby improving the drainage efficiency.

[0067] Meanwhile, the base 100 is provided with a water storage section 110 and a drain outlet 500. Condensate flows from the flow chamber 400 to the water storage section 110 and then is discharged through the drain outlet 500, thereby avoiding the problem that condensate will remain in the entire flow chamber 400 when the flow of condensate is not smooth.

[0068] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, 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 all fall within the protection scope of this utility model.
