Description

Technical Field

[0001] This utility model relates to the field of air conditioning de-icing technology, and in particular, to an outdoor unit water collection tray and an air conditioner. Background Technology

[0002] Currently, air conditioner outdoor units are increasingly used in air source heat pump products in northern regions. Faced with low temperatures, the existing air conditioner chassis drainage structure cannot drain water smoothly, leading to icing and the ice layer becoming thicker and thicker, eventually causing the outdoor unit to fail.

[0003] For outdoor air conditioning units in northern winters, especially those operating in low-temperature and high-humidity environments (such as -7℃ / -8℃), they may undergo multiple defrosting cycles during long-term heating operation. During defrosting, a large amount of defrosting water will be released from the outdoor heat exchanger. Under normal circumstances, the defrosting water cannot be completely drained through the drain hole via the water guide groove. When defrosting is finished, the water on the chassis is often not completely drained.

[0004] If the water does not completely drain from the air conditioner chassis, when the air conditioner switches back to heating mode after defrosting, the surface temperature of the outdoor heat exchanger will be very low. Due to the low outdoor ambient temperature, the water will freeze on the chassis components and accumulate at the bottom of the outdoor heat exchanger. Over time, this ice layer will become thicker and thicker, eventually affecting the heat exchanger's heat exchange efficiency. In severe cases, it may cause liquid backflow, leading to liquid slugging in the compressor and affecting its safe and reliable operation. The accumulation of ice at the bottom of the outdoor heat exchanger will result in incomplete defrosting, affecting the heat exchange efficiency, leading to poor heating performance, a significantly shortened defrosting cycle, and prolonged defrosting time. Consequently, the indoor room temperature cannot be guaranteed, affecting the user's heating comfort.

[0005] In the existing technology, there are two main methods for removing frost from the chassis of an air conditioner outdoor unit: one is to rely entirely on the condensation heat of the outdoor unit's heat exchanger during defrosting to remove frost from the heat exchanger and chassis; the other is to install electric heating belts and electric heating tubes on the chassis in addition to relying on the system's condensation heat to assist in defrosting.

[0006] The two de-icing methods described above have the following disadvantages: The former may result in residual ice accumulation due to insufficient condensation heat or uneven placement of the prototype, leading to incomplete de-icing; the latter has the following disadvantages: the electric heating tubes and heating belts of the chassis are connected to high voltage, posing issues such as preventing leakage, electrical safety, and certification, and requiring complex design of electrical wiring and logic control; in addition, the electric heating tubes and heating belts of the chassis have a relatively low safety factor during use, and long-term use in various harsh outdoor environments may lead to oxidation leakage, tube / belt bursting accidents, etc., resulting in poor long-term stability. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, this utility model provides a water collection tray for an outdoor unit of an air conditioner and an air conditioner, so as to solve the problems that the existing de-icing method of the outdoor unit chassis of an air conditioner will result in residual ice accumulation, incomplete de-icing, or complex electrical wiring and logic control, and even long-term safety issues.

[0008] The technical solution adopted by this utility model to solve its technical problem is: In one aspect, an outdoor unit water collection tray for an air conditioner is provided, including a chassis upper base and a refrigerant flow channel plate; The upper bottom of the chassis is located below the outdoor heat exchanger to collect water dripping from the outdoor heat exchanger; The refrigerant flow channel plate is located on the upper and lower part of the chassis, and the refrigerant flow channel plate is provided with refrigerant flow pipes.

[0009] As an optional implementation of this application, the refrigerant flow pipe is connected to the refrigerant circulation loop in the air conditioner so as to send the refrigerant in the refrigerant circulation loop into the refrigerant flow pipe.

[0010] As an optional implementation of this application, it also includes: a heater; The heater is used to heat the refrigerant flowing from the refrigerant circulation loop into the refrigerant flow pipe.

[0011] As an optional implementation of this application, the chassis is provided with a drainage structure on the bottom.

[0012] As an optional implementation of this application, it also includes: A baffle and a drain pipe, wherein the baffle is disposed between the upper bottom of the chassis and the refrigerant flow channel plate, for preventing water on the upper bottom of the chassis from flowing into the refrigerant flow channel plate; The upper bottom of the chassis includes a water inlet, through which water on the upper bottom of the chassis flows into the baffle. The baffle is provided with a flow guide groove, and the end of the flow guide groove is connected to the drain pipe.

[0013] As an optional implementation of this application, the drain pipe is connected to the drain outlet of the indoor unit of the air conditioner.

[0014] As an optional implementation of this application, it also includes: a chassis underbody; The chassis bottom is located below the refrigerant flow channel plate and is used to fix and protect the refrigerant flow channel plate.

[0015] As an optional implementation of this application, it further includes: the refrigerant flow pipe is bent into multiple n-shaped pipes connected end to end on the refrigerant flow channel plate, and the distance between the n-shaped pipes is smaller the farther away from the inlet of the refrigerant flow pipe.

[0016] In a second aspect, an air conditioner is provided, comprising a compressor, a four-way reversing valve, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger, and further comprising: a control valve and a drip tray as described in any of the preceding claims; The control valve is used to control whether the refrigerant in the refrigerant circulation loop of the air conditioner enters the refrigerant flow pipe in the water receiving pan.

[0017] As an optional implementation of this application, it also includes: a heater.

[0018] The heater is located between the control valve and the water receiving pan, and is used to heat the refrigerant flowing from the control valve to the water receiving pan.

[0019] The application employs the above technical solution and has at least the following beneficial effects: This application provides a water collection tray for an outdoor unit of an air conditioner and an air conditioner. The water collection tray includes a base and a refrigerant flow channel plate. The base is located below the outdoor heat exchanger to collect water dripping from the heat exchanger. The refrigerant flow channel plate is located below the base and has refrigerant flow pipes. By introducing high-temperature refrigerant into the flow pipes, the ice on the base can be melted by the refrigerant's temperature. Because this design directly addresses the issue below the base, heating is uniform. Furthermore, since a heater is not required, it is safe, reliable, simple in design, and low in cost. The refrigerant in the flow pipes can be directly supplied from the air conditioner's refrigerant circulation loop, eliminating the need for a separate supply. It can even achieve defrosting while maintaining heating indoors, significantly improving the user experience. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Reference Figures 1-5 This utility model embodiment provides a water receiving tray for an outdoor unit of an air conditioner, including a chassis upper bottom 13 and a refrigerant flow channel plate 14; The upper bottom 13 of the chassis is located below the outdoor heat exchanger and is used to collect water dripping from the outdoor heat exchanger. The refrigerant flow channel plate 14 is located below the upper bottom 13 of the chassis, and a refrigerant flow pipe is provided on the refrigerant flow channel plate 14.

[0025] In a preferred embodiment of this application, the refrigerant flow pipe is connected to the refrigerant circulation loop in the air conditioner so as to send the refrigerant in the refrigerant circulation loop into the refrigerant flow pipe.

[0026] Preferably, the high-temperature refrigerant in the refrigerant circulation loop is sent into the refrigerant flow pipe. Specifically, a portion of the high-temperature, high-pressure refrigerant directly exiting from the compressor 6 or the four-way reversing valve 7 is sent into the refrigerant flow pipe, while the other portion still enters the refrigerant circulation loop.

[0027] Understandably, the air conditioner can operate in heating mode or defrost mode (i.e., defrosting via the four-way reversing valve 7, where the refrigerant flow direction in the refrigerant circulation loop is the same as in cooling mode). Operating in heating mode will not affect the indoor temperature. Operating in defrost mode allows for faster defrosting. The choice depends on actual needs.

[0028] Of course, in reality, a separate refrigerant tank can be set up to provide a higher temperature refrigerant to the refrigerant circulation pipeline, but this requires additional components and is not as convenient as the above embodiment.

[0029] To accelerate defrosting, a heater 10 may also be provided in this embodiment; The heater 10 is used to heat the refrigerant flowing from the refrigerant circulation loop into the refrigerant flow pipe.

[0030] In another optional embodiment where heater 10 is installed, the refrigerant circulating back at a medium to low temperature can be sent into the refrigerant circulation pipe after passing through heater 10. For example, when operating in heating mode, a portion of the refrigerant after passing through indoor heat exchanger 3 is diverted into the refrigerant circulation pipe; or when operating in defrost mode, a portion of the refrigerant after passing through outdoor heat exchanger is diverted into the refrigerant circulation pipe. The advantage of this arrangement is that it does not affect the amount of refrigerant used for defrosting or indoor heating.

[0031] The refrigerant flow channel plate 14 can not only melt the ice on the bottom 13 of the chassis, but also defrost the bottom of the outdoor heat exchanger.

[0032] In one embodiment, the upper bottom 13 of the chassis is provided with a drainage structure, that is, the melted water flows directly out of the upper bottom 13 of the chassis through the drainage structure.

[0033] In another embodiment, reference Figure 3 Because the chassis base 13 has a structure for fixing the condenser and other parts, direct drainage can be affected. Therefore, a drain hole 19 is provided to allow water on the chassis to flow down into the chassis. To prevent the flowing water from affecting the refrigerant flow channel plate 14 below, the following is also included: Baffle 15 and drain pipe 18, wherein the baffle 15 is disposed between the upper bottom 13 of the chassis and the refrigerant flow channel plate 14, for preventing water on the upper bottom 13 of the chassis from flowing into the refrigerant flow channel plate 14; The upper bottom 13 of the chassis includes a water inlet 19, through which water on the upper bottom 13 of the chassis flows into the baffle 15; The baffle 15 is provided with a flow guide groove 16, and the end of the flow guide groove 16 is connected to the drain pipe 18.

[0034] The baffle 15 is provided with bolt holes 17, and the baffle 15 and the refrigerant flow channel plate 14 are fixed by bolts and bolt holes 17.

[0035] Because outdoor temperatures are low in winter, to prevent the water flowing from the drain pipe 18 from freezing and causing pedestrians to slip, in this embodiment of the application, the drain pipe 18 is connected to the drain outlet of the indoor unit of the air conditioner. The drain outlet of the indoor unit discharges water from the sewer, rather than directly onto the ground.

[0036] As a preferred implementation of this application, it also includes: a chassis bottom 12; The chassis bottom 12 is located below the refrigerant flow channel plate 14 and is used to fix and protect the refrigerant flow channel plate 14.

[0037] It should be noted that the refrigerant flow pipe is bent into multiple n-shaped pipes connected end to end on the refrigerant flow channel plate 14. This arrangement allows the refrigerant in the refrigerant flow pipe to dissipate heat fully, thereby improving the de-icing effect.

[0038] In one embodiment, the n-type pipes are equidistant, meaning that the distance between any two adjacent pipes is the same. However, in actual use, due to heat dissipation from the refrigerant within the refrigerant flow pipe, its temperature will gradually decrease. The outlet and inlet of the refrigerant flow pipe are located on both sides of the refrigerant flow channel plate 14 (i.e.,...). Figure 2 or Figure 4 The two short sides of the refrigerant flow channel plate 14 can easily cause poor de-icing at the outlet of the refrigerant flow pipe.

[0039] Therefore, in another embodiment, the further away from the inlet of the refrigerant flow pipe, the smaller the distance between the n-shaped pipes.

[0040] Alternatively, the outlet and inlet of the refrigerant flow pipe can be located on the same side as the refrigerant flow channel plate 14 (i.e., located on...). Figure 2 or Figure 4 The same short side of the refrigerant flow channel plate 14 is equivalent to... Figure 2 or Figure 4 (Based on the example shown, then circle back to the entrance in the same way).

[0041] The water receiving tray 5 provided in this embodiment includes a chassis upper bottom 13 and a refrigerant flow channel plate 14. The chassis upper bottom 13 is located below the outdoor heat exchanger and is used to collect water dripping from the outdoor heat exchanger. The refrigerant flow channel plate 14 is located below the chassis upper bottom 13 and has a refrigerant flow pipe. In this way, as long as a high-temperature refrigerant is introduced into the refrigerant flow pipe, the ice on the chassis upper bottom 13 can be melted by the temperature of the refrigerant. Since this application is directly located below the chassis upper bottom 13, the heating is uniform. Moreover, since there is no need to install a heater 10, it is safe and reliable, and the design is simple and low-cost.

[0042] Based on the same inventive concept, this application provides an air conditioner, such as... Figure 6 and Figure 7 As shown: It includes a compressor 6, a four-way reversing valve 7, an outdoor heat exchanger 1, an expansion valve 22 and an indoor heat exchanger 3, and also includes a control valve 8 and a water receiving tray 5 as provided in the above embodiment; The control valve 8 is used to control whether the refrigerant in the refrigerant circulation loop of the air conditioner enters the refrigerant flow pipe in the water receiving pan 5.

[0043] As a preferred implementation of this application, it further includes: heater 10; The heater 10 is disposed between the control valve 8 and the water receiving pan 5, and is used to heat the refrigerant flowing from the control valve 8 to the water receiving pan 5.

[0044] In one embodiment, such as Figure 6 As shown, the control valve 8 includes a first port, a second port, and a third port. The first port and the second port are located in the refrigerant circulation loop of the air conditioner and are respectively connected to the four-way reversing valve 7 and the indoor heat exchanger 3; the third port is connected to the refrigerant flow pipe. When the air conditioner is in heating mode, the first and second ports of the control valve 8 are open, so that the refrigerant enters the first port of the control valve 8 through the four-way reversing valve 7 and then enters the indoor heat exchanger 3 through the second port of the control valve 8; when it is necessary to defrost the drip tray 5, the third port of the control valve 8 is open; when it is not necessary to defrost the drip tray 5, the third port of the control valve 8 is closed.

[0045] When defrosting of water pan 5 is required, the air conditioner operates in heating mode, and the refrigerant flow path is as follows: Compressor 6 compresses the refrigerant to obtain high-temperature, high-pressure refrigerant. After passing through the four-way reversing valve 7, it flows into the first port of control valve 8. The refrigerant then splits into two paths. One path flows directly from the third port of control valve 8 into the refrigerant flow channel plate 14 of the water collection pan 5 (or is further heated by heater 10 before entering the refrigerant flow channel plate 14 of the water collection pan 5), melting the ice in the water collection pan 5, and then returns to compressor 6 after passing through gas-liquid separator 4. The other path flows directly from the second port of control valve 8 into indoor heat exchanger 3, then sequentially passes through expansion valve 22, outdoor heat exchanger 1, the four-way valve, and gas-liquid separator 4 before returning to compressor 6. A cross-flow fan 11 is installed at indoor heat exchanger 3, and an axial flow fan 9 is installed at outdoor heat exchanger 1.

[0046] In this embodiment, since the refrigerant coming out of the four-way valve is a high-temperature and high-pressure refrigerant, it can be directly distributed into the water tray 5. When the indoor heating demand is not high, the power of the heater 10 can be reduced or the heater 10 can be eliminated.

[0047] However, when the indoor heating demand is high, some refrigerant enters the water collection pan 5, resulting in a reduction in the amount of refrigerant entering the indoor heat exchanger 3. This may cause the indoor temperature to fail to reach the set temperature, or take a long time to reach the set temperature, affecting the user experience.

[0048] Therefore, in another embodiment of this application, another type of air conditioner is provided, such as... Figure 7 As shown, the control valve 8 includes a first port, a second port, and a third port. The first port and the second port are located in the refrigerant circulation loop of the air conditioner. The first port is connected to the refrigerant outlet of the indoor heat exchanger 3 or the refrigerant outlet of the expansion valve 22. The second port is connected to the refrigerant inlet of the outdoor heat exchanger 1. The third port is connected to the refrigerant flow pipe. When the air conditioner is running, the first and second ports of the control valve 8 are in the open state; When it is necessary to de-ice the water receiving tray 5, the third port of the control valve 8 is in the open state; when it is not necessary to de-ice the water receiving tray 5, the third port of the control valve 8 is in the closed state.

[0049] by Figure 7 As shown in the diagram, when de-icing of the water pan 5 is required, the air conditioner operates in heating mode, and the refrigerant flow path is as follows: Compressor 6 compresses the refrigerant to obtain high-temperature, high-pressure refrigerant, which flows into the indoor heat exchanger 3 after passing through the four-way reversing valve 7. After exiting the indoor heat exchanger 3, it passes through the expansion valve 22 and enters the first port of the control valve 8. The refrigerant then splits into two paths: one path flows from the third port of the control valve 8, passes through the heater 10 for further heating, and then enters the refrigerant flow channel plate 14 of the drip tray 5 to melt ice in the drip tray 5, before returning to the compressor 6 after passing through the gas-liquid separator 4. The other path flows directly into the outdoor heat exchanger 1 from the second port of the control valve 8, then passes through the four-way valve and the gas-liquid separator 4 before returning to the compressor 6. A cross-flow fan 11 is installed at the indoor heat exchanger 3, and an axial flow fan 9 is installed at the outdoor heat exchanger 1.

[0050] In this embodiment, since the refrigerant after the indoor heat exchanger 3 is at a low temperature, it needs to be heated by the heater 10 before being distributed into the water collection pan 5. Although the heater 10 has a high power, the indoor temperature is less affected because the refrigerant at the indoor heat exchanger 3 is not different from the refrigerant during normal heating, thus improving the user experience.

[0051] The air conditioner provided in this application embodiment can still operate in heating mode while de-icing the water tray 5, ensuring a suitable indoor temperature and improving the user experience.

[0052] The following provides a specific implementation method: During defrosting of the outdoor heat exchanger, the frost crystals melt and drip into a drip tray located below the heat exchanger, then drain through a drain pipe connected to the tray. However, when the ambient temperature is low, the water in the drip tray may freeze, clogging the drain pipe and preventing drainage. As the air conditioner operates, the ice buildup on the drip tray increases, potentially causing the air conditioner to malfunction. Currently, there is no good solution in the industry. This invention proposes a novel outdoor unit drip tray and air conditioning system, where the drip tray is as follows... Figures 1-5 As shown, the structures of the baffle 15 and the refrigerant flow channel plate 14 are as follows: Figure 4 As shown, the baffle and heating element are fixed to the bottom of the chassis with bolts. The baffle 15 has a water guide groove 16 on its surface. The water guide groove 16 can remove the defrosting water formed by residual ice heating in time, preventing the accumulation of residual ice from affecting the heating effect. The air conditioning system consists of a piping system, a temperature sensor and a control valve 8. The bottom of the outdoor unit chassis 13 is equipped with a temperature sensor. The temperature sensor controls the opening of the control valve 8 and the power supply of the heater 10 by sensing the temperature. The refrigerant (liquid) has a low freezing point. Even at tens of degrees below zero, it can operate normally during defrosting, and its application range is wider.

[0053] When the temperature sensor detects a decrease in heating performance (at this time, the outdoor heat exchanger 1 has already frozen, causing a decrease in heating performance), the heater 10 (which can be installed indoors or outdoors) is powered on. The refrigeration system distributes a portion of the refrigerant, which first passes through the control valve 8 and then enters the heater 10 for heating. After that, it enters the interlayer between the upper bottom 13 and the lower bottom 12 of the chassis connected to the outdoor heat exchanger 1. The high-temperature refrigerant (gas) melts the ice on the upper bottom 13 of the chassis into water in a short time through heat exchange. At the same time, the heat can also remove the ice at the bottom of the outdoor heat exchanger 1 through heat conduction (under the action of gravity, water will accumulate at the bottom of the outdoor heat exchanger 1, so there is more ice at the bottom of the outdoor heat exchanger 1), achieving de-icing without stopping the machine and improving heating efficiency. Additionally, the melted water flows from the drainage hole 19 on the bottom of the chassis 13 to the baffle 15, and is quickly discharged into the drain pipe 18 of the outdoor unit through the water guide channel 16 on the baffle 15. The drain pipe 18 of the outdoor unit is connected to the drain pipe of the indoor unit, which can prevent the drain pipe 18 of the outdoor unit from dripping water directly onto the ground, causing the ground to freeze and pedestrians to slip and fall. When the temperature sensor detects that the heating performance is no longer decreasing (at this time, the ice on the outdoor heat exchanger 1 and the bottom of the chassis 13 has completely melted, and the heating performance begins to recover), the heater 10 stops being powered on, and the control valve 8 closes.

[0054] The structure provided in this application embodiment can maintain the heating mode while de-icing the outdoor heat exchanger, thereby improving the user experience.
