Description

Technical Field

[0001] This invention relates to the field of air conditioner outdoor unit drainage technology, and more specifically, to a drainage device and an air conditioner having the same. Background Technology

[0002] In existing window air conditioner technology, a drain outlet and a water-discharging fan are installed on the outdoor side. When the water-discharging fan rotates, it carries the condensate in the water collection tray and sprays it onto the outdoor heat exchanger to cool it down. When the user is not using the air conditioner, the condensate is discharged through the drain outlet.

[0003] However, this method requires users to manually block or open the drain outlet. When the user opens the drain outlet, the condensate is completely drained, and the outdoor heat exchanger cannot be increased by flushing water, resulting in reduced cooling / heating efficiency. If the drain outlet is blocked for a long time, dirt will accumulate on the drain pipe and the chassis inside the unit, which will block the water passages on the chassis inside the unit, reducing the drainage speed. It may even block the drain pipe, causing the water level to rise and overflow, resulting in problems such as air conditioner leakage. Summary of the Invention

[0004] The main objective of this invention is to provide a drainage device and an air conditioner having the same, so as to solve the problem that the drain outlet in the prior art window air conditioner cannot automatically switch between drainage and blocking states.

[0011] Furthermore, the water receiving tray is provided with a groove surrounding the drain outlet; at least a portion of the sealing component is in contact with the groove wall surface so that the sealing component is in a blocking position.

[0012] Furthermore, the water receiving tray is provided with a manifold body, and the drain outlet is provided on the manifold body; the drainage device also includes: a drain pipe, the end of the drain pipe is provided with a groove, the groove extends along the circumferential direction of the drain pipe, and the manifold body surrounding the drain outlet is locked in the groove so that the drain outlet is connected to the drain pipe; wherein, the drain pipe and the manifold body are interference fit.

[0013] Furthermore, the inner diameter of the drain outlet is d, where 10mm ≤ d ≤ 40.

[0014] According to another aspect of the present invention, an air conditioner is provided, including a body and a drainage device, wherein the drainage device is disposed in the body and is the drainage device described above.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] As mentioned in the background section, in existing air conditioners, the condensate produced by the outdoor heat exchanger during heat exchange collects on a drip tray. To improve the heat exchange efficiency of the outdoor heat exchanger, a water hose is usually installed on the outdoor fan to carry the condensate to the outdoor heat exchanger for cooling. However, after prolonged use, when too much condensate accumulates on the drip tray, the user can only open the drain outlet of the drip tray to completely drain the condensate. Afterward, the user needs to manually seal the drain outlet to continue collecting condensate. Thus, sealing or opening the drain outlet can only be done manually, and the drain outlet cannot automatically switch between draining and sealing states. Therefore, in order to solve the above-mentioned technical problems, the drainage device provided in this application is provided with a sealing component 200. The sealing component 200 is movably arranged to block or avoid the drain outlet 110, so as to seal or open the drain outlet. The sealing component 200 is provided with a sealing space 210, and a sealing cavity 220 is formed between the sealing space 210 and the water receiving tray 100 to seal the drain outlet 110. At least a part of the sealing component 200 is elastically arranged, so that when the sealing component 200 deforms, it can compress the sealing cavity 220, increase the air pressure in the sealing cavity 220, and push the fluid accumulated in the sealing cavity 220 into the drain outlet 110 for discharge. In this way, by controlling the moving position of the sealing component 200, the drain outlet can automatically switch between drainage state and sealing state to improve the automatic control of the air conditioner. When the flow of condensate is large, the sealing component 200 is controlled to move to the avoidance position to discharge part or all of the condensate. Then, the sealing component 200 is controlled to move to the blocking position to seal the drain outlet.

[0030] Please refer to Figures 1 to 6The present invention also provides a drainage device disposed on a water receiving tray 100, the water receiving tray 100 having a drain outlet 110. The drainage device includes: a sealing member 200 opposite to the drain outlet 110, the sealing member 200 being movably disposed to block or avoid the drain outlet 110; a sealing space 210 disposed on the sealing member 200, the sealing space 210 and the water receiving tray 100 forming a sealing cavity 220, so that the sealing member 200 is in a blocking position to block the drain outlet 110; wherein, at least a portion of the sealing member 200 is elastically disposed to compress the sealing cavity 220, pushing the fluid in the sealing cavity 220 into the drain outlet 110 for discharge.

[0031] According to the drainage device provided in this application, a drain outlet 110 is provided on a water receiving tray 100. The device includes: a sealing member 200, which is opposite to the drain outlet 110. The sealing member 200 is movably positioned to block or avoid the drain outlet 110. A sealing space 210 is provided on the sealing member 200, and a sealing cavity 220 is formed between the sealing space 210 and the water receiving tray 100, so that the sealing member 200 is in a blocking position to block the drain outlet 110. At least a portion of the sealing member 200 is elastically positioned to compress the sealing cavity 220 and push the fluid in the sealing cavity 220 into the drain outlet 110 for discharge. This configuration allows the sealing component 200 to control the drain outlet 110 to be in a sealed or draining state. When a sealed cavity 220 is formed between the sealing component 200 and the water receiving tray 100, the drain outlet 110 is sealed. At the same time, the sealing component 200 can be repeatedly moved between a blocking position and a clearance position. When it is in the blocking position, the sealing component 200 is squeezed and deformed to push the fluid in the sealed cavity 220 into the drain outlet 110 for discharge. This can accelerate the discharge speed of the fluid. At the same time, the fluid oscillation caused by the repeated movement of the sealing component 200 can also be used to discharge dirt and impurities in the fluid along with the fluid from the drain outlet 110.

[0032] In the drainage device provided in this application, the sealing component 200 includes three states: a clearance position that avoids the drain outlet 110, in which the drain outlet 110 is open and condensate is discharged autonomously from the drain outlet 110; a blocking position that blocks the drain outlet 110, in which the drain outlet 110 is sealed by the sealing cavity 220 to prevent condensate from being discharged; and a state in which the sealing component 200 repeatedly moves between the blocking position and the clearance position, and is squeezed when in the blocking position. In this state, the sealing component 200 is used to increase the discharge speed of condensate. During the repeated movement, the sealing component 200 generates vibrations in the condensate, allowing deposited dirt and impurities to float in the condensate, and by compressing the sealing cavity 220, the discharge of condensate and dirt mixture is accelerated.

[0033] In the embodiments provided in this application, the sealing member 200 extends along a predetermined arcuate trajectory to form a sealed space 210; the sealing member 200 covers the drain outlet 110 and fits against the water receiving tray 100 to be in a blocking position. Preferably, the sealing member 200 has a hemispherical structure, which allows it to maintain a good fit with the water receiving tray 100. At the same time, compared with a prismatic structure, it avoids the problem of angles being generated on the sealing member 200, which can easily cause stress concentration when the sealing member 200 deforms, reducing its service life.

[0034] Preferably, the sealing component 200 is made of rubber.

[0035] Specifically, the drainage device further includes a power assembly 300 connected to the sealing member 200. At least a portion of the power assembly 300 is movably configured to drive the sealing member 200 to move. After the power assembly 300 drives the sealing member 200 to a blocking position, the power assembly 300 continues to move, compressing the sealing member 200 to compress the sealing cavity 220. This configuration allows the power assembly 300 to drive the sealing member 200, thereby controlling the position of the sealing member 200 and enabling switching between different positions.

[0036] Further, the power assembly 300 includes: a telescopic component 310 connected to the sealing component 200, the telescopic component 310 being vertically telescopic, used to move or compress the sealing component 200; and a drive component 320 connected to the telescopic component 310 for driving the telescopic component 310 to extend or retract. Preferably, the drive component 320 is a cylinder, and the telescopic component 310 is a piston rod, or the telescopic component 310 is a hydraulic rod. This configuration is simple and easy to implement, controlling the sealing component 200 through cylinder or hydraulic drive. When the user selects the drainage mode, the telescopic component retracts to drain water from the drain outlet; when the user selects the non-drainage mode, the telescopic component extends to seal the drain outlet.

[0037] To protect the power component 300, the drainage device further includes: a protective housing 400, which covers and connects to the power component 300; the protective housing 400 has a wire hole 410 through which the connecting wire of the power component 300 passes to connect to the power source; the protective housing 400 also has a clearance opening 420, which forms a clearance channel with the water receiving tray 100 to allow fluid to pass through, and the fluid in the water receiving tray 100 flows into the drain outlet 110 through the clearance channel. Preferably, there are multiple clearance openings 420, which are spaced apart circumferentially along the protective housing 400. Adjacent clearance openings 420 have a mounting portion, and the protective housing 400 is connected to the water receiving tray 100 through the mounting portion. This achieves both the fixation of the protective housing 400 and provides a clearance channel for condensate using the clearance openings 420.

[0038] In specific implementation, such as Figure 1 As shown, the drainage device further includes: a liquid level detection component 500, disposed within the water receiving pan 100, for detecting the liquid flow rate within the water receiving pan 100; the liquid level detection component 500 is signal-connected to the power assembly 300, and the power assembly 300 drives the sealing component 200 to a clearance position, a blocking position, or a compression state based on the detection result of the liquid level detection component 500. Preferably, the liquid level detection component 500 is a liquid level sensor. By setting up a liquid level detection component 500, the liquid level of condensate is monitored in real time. When the condensate level reaches the first upper limit position, a signal is transmitted to the power component 300. The power component 300 controls the sealing component 200 to move to an avoidance position, opening the drain outlet 110 and draining the condensate. When the condensate level reaches the second upper limit position, a signal is transmitted to the power component 300. The power component 300 controls the sealing component 200 to repeatedly move between a blocking position and a sealing position, while simultaneously squeezing the sealing component 200 to achieve rapid drainage of the condensate. When the condensate level reaches the third position, the liquid level detection component 500 transmits a signal to the power component 300, which controls the sealing component 200 to move to a blocking position, sealing the drain outlet 110. The second upper limit position is higher than the first upper limit position, and the third position is lower than the second upper limit position.

[0039] To ensure a tighter fit between the sealing component 200 and the drip tray 100, and to limit the sealing component 200, a groove 120 is provided on the drip tray 100, surrounding the drain outlet 110. At least a portion of the sealing component 200 is in contact with the groove wall of the groove 120, thus placing the sealing component 200 in a blocking position. Since condensation always exists inside the drip tray 100, the sealing component 200 is prone to slippage during repeated contact with the drip tray 100. The groove 120 limits the sealing component 200, ensuring it remains in contact with the groove wall, thereby optimizing the sealing effect.

[0040] Furthermore, a manifold body 130 is provided on the water receiving tray 100, and a drain outlet 110 is provided on the manifold body 130; the drainage device also includes a drain pipe 600, the end of which is provided with a groove 610, the groove 610 extending along the circumferential direction of the drain pipe 600, and the manifold body 130 enclosing the drain outlet 110 is fitted in the groove 610 so that the drain outlet 110 communicates with the drain pipe 600; wherein, the drain pipe 600 and the manifold body 130 are interference-fitted. This arrangement can improve the tightness of the fit between the drain pipe 600 and the manifold body 130. Preferably, the surface of the manifold body 130 is lower than the surface of the water receiving tray 100, so that the condensate in the water receiving tray 100 can flow into the manifold body 130 and then be discharged through the drain outlet 110.

[0041] Preferably, the inner diameter of the drain outlet 110 is d, where 10mm ≤ d ≤ 40. The minimum diameter of the slot 610 is greater than the inner diameter of the drain outlet 110.

[0042] The drainage device of this invention uses a movable sealing element (the aforementioned sealing component 200) to seal and open the product's drain outlet. By controlling the movement of the sealing element, the user can select between a drainage mode and a non-drainage mode (sealing mode), thus facilitating the selection of a high-performance energy-saving state or a lower-performance state. A bowl-shaped sealing element, with its edge positioned and fitted onto the drain outlet, compresses and deforms, pressurizing the drain outlet and the inner cavity of the water pipe, effectively removing sludge and other contaminants. Through water level detection (liquid level detection component) and drainage control, water is concentrated and drained once it reaches a certain height, allowing a large volume of water to flush away dirt and blockages, achieving a cleaning function within the machine.

[0043] The sealing element fits tightly against and seals the drain outlet. The drain pipe is installed at the drain outlet. The telescopic component (the aforementioned telescopic part 310) is connected to the sealing element. The telescopic component and the detection component are installed on the mounting component. This device can control the sealing of the drain outlet through the telescopic sealing element, solving the problem of common sealing valves being easily clogged by dirt. The cup-shaped deformation of the sealing element increases pressure at the drain outlet, allowing dirt and other contaminants in the drain pipe to be discharged.

[0044] like Figure 3 As shown, when the seal is in position t0, the drain outlet can be sealed, as follows. Figure 5 As shown, when the seal is in position t1, drainage from the drain outlet is achieved; when the seal is in position t2, pressure is applied to the drain pipe, causing internal contaminants to be ejected. Continuous pressure and drainage are achieved by allowing the seal to change position continuously.

[0045] Once the water level reaches a certain height, the detection element receives a signal and makes a judgment. The telescopic component then drives the sealing component to continuously extend and retract, causing the condensate in the water tank to vibrate. The flow and impact of the condensate suspend dirt in the condensate, which then flows into the drain pipe. Simultaneously, the sealing component pressurizes the drain outlet, enabling faster and more forceful drainage.

[0046] like Figure 7 As shown, when the sewage discharge function is activated, the drainage device enters a non-drainage state. The indoor and outdoor motors are controlled, setting the indoor and outdoor fan blades to operate at set speeds (generally lower indoor speed and higher outdoor speed). The compressor also enters a set frequency (generally higher frequency and higher load operation), allowing the product to quickly generate a large amount of condensate. The drainage device's detection element checks if the water level reaches the set height. Then, the telescopic component continuously extends and retracts the sealing element at positions t1 and t2, continuously pressurizing the drain pipe, thus allowing water to carry away the contaminants. This constitutes one P cycle. After several P cycles, the contaminants inside the product have been discharged.

[0047] This application enables users to choose between drainage and non-drainage modes, avoiding complex product disassembly and assembly, and simplifying existing water collection box installation steps. It also addresses the issue of water tanks and drain pipes becoming easily dirty and clogged after long-term use, extending product lifespan and reducing after-sales maintenance.

[0048] In this application, the expansion joints and seals can be replaced with electronic sealing valves. However, because there is a large amount of dirt in the water, the service life of the electronic sealing valve materials will be reduced. Furthermore, electronic sealing valves are already easily clogged by dirt.

[0049] In this application, the connection between the drain pipe and the drain outlet can be replaced by a non-groove sealing structure. The method of vibrating condensate and quickly discharging it to achieve the sewage discharge effect can be replaced by other similar vibration or operation structures, but the sewage discharge principle is the same.

[0050] like Figure 6 As shown, the present invention also provides an air conditioner, including a body and a drainage device 800, wherein the drainage device 800 is disposed in the body and is the drainage device described above.

[0051] The air conditioner also includes a compressor 710, an outdoor heat exchanger 720, a fan blade 730, a water-cooling ring 740, and a partition 750. The partition 750 is used to divide the air conditioner into a heat exchange chamber and a compressor chamber. The compressor 710 is located in the compressor chamber and is connected to the outdoor heat exchanger 720. The water-cooling ring 740 is located on the fan blade 730. As the fan blade 730 rotates, the water-cooling ring 740 pumps condensate onto the outdoor heat exchanger 720 to cool it. The drainage device 800 is located in the heat exchange chamber.

[0052] The drain device of the present invention is provided for a window air conditioner with its drain outlet located on the outdoor side. The drain device is located at the drain outlet. When the drain function is turned on, the window air conditioner enters the drain method. By setting the fan speed, compressor frequency, etc., condensate is quickly extracted. The water level is detected by the detection element of the drain device and reaches a specified height. The position of the sealing element is controlled to drain the water, thereby achieving the discharge of a large amount of accumulated water and cleaning the dirt inside the unit, thus realizing the drain function.

[0053] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0054] According to the drainage device provided in this application, a drain outlet 110 is provided on a water receiving tray 100. The device includes: a sealing member 200, which is opposite to the drain outlet 110. The sealing member 200 is movably positioned to block or avoid the drain outlet 110. A sealing space 210 is provided on the sealing member 200, and a sealing cavity 220 is formed between the sealing space 210 and the water receiving tray 100, so that the sealing member 200 is in a blocking position to block the drain outlet 110. At least a portion of the sealing member 200 is elastically positioned to compress the sealing cavity 220 and push the fluid in the sealing cavity 220 into the drain outlet 110 for discharge. This configuration allows the sealing component 200 to control the drain outlet 110 to be in a sealed or draining state. When a sealed cavity 220 is formed between the sealing component 200 and the water receiving tray 100, the drain outlet 110 is sealed. At the same time, the sealing component 200 can be repeatedly moved between a blocking position and a clearance position. When it is in the blocking position, the sealing component 200 is squeezed and deformed to push the fluid in the sealed cavity 220 into the drain outlet 110 for discharge. This can accelerate the discharge speed of the fluid. At the same time, the fluid oscillation caused by the repeated movement of the sealing component 200 can also be used to discharge dirt and impurities in the fluid along with the fluid from the drain outlet 110.

[0055] This solves the problem that users cannot easily switch between drainage and non-drainage modes after installing window air conditioners, making it inconvenient for users to select between high-efficiency water-filling mode and normal non-water-filling mode.

[0056] This solution simplifies the installation process for window air conditioners, which previously required removing rubber plugs, installing drain boxes and water pipes, making the installation process more complex.

[0057] This solution addresses issues such as sludge and dirt accumulating in the condensate water system after long-term use, leading to blockages, corrosion, and reduced product lifespan, as well as unpleasant odors.

[0058] This solution addresses the problem of slow or no drainage, leading to leaks and drips, caused by dirty water pipes or water channels.
