[0002] In the existing window air conditioner technology, a drain outlet and a water-blowing blade are provided on the outdoor side.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] As mentioned in the background technology, on the outdoor side of the existing air conditioner, condensed water generated by the outdoor heat exchanger during the heat exchange process will collect in the water collecting pan. In order to improve the heat exchange efficiency of the outdoor heat exchanger, a water pump is usually provided on the outdoor fan to bring the condensed water to the outdoor heat exchanger to cool the outdoor heat exchanger. However, after the air conditioner has been used for a long time, when too much condensed water accumulates in the water collecting pan, the user can only open the drain port of the water collecting pan to completely drain the condensed water. After that, the user needs to seal the drain port by himself to continue to collect the condensed water. In this way, the sealing or opening of the drain port can only be done manually, and the drain port cannot automatically switch between the drainage state and the sealing state. Therefore, in order to solve the above technical problems, the drainage device provided by the present application is provided with a sealing component 200, and the sealing component 200 is movably arranged to block or avoid the drainage outlet 110 to achieve the blocking or opening of the drainage outlet. A sealing space 210 is arranged on the sealing component 200, and a sealing cavity 220 is formed between the sealing space 210 and the water receiving tray 100 to seal the drainage outlet 110. At least a part of the sealing component 200 can be elastically arranged, so that when the sealing component 200 is deformed, the sealing cavity 220 can be compressed to increase the air pressure in the sealing cavity 220, and the fluid accumulated in the sealing cavity 220 is pushed into the drainage outlet 110 for discharge. In this way, by controlling the moving position of the sealing component 200, the drainage outlet can be automatically switched to the drainage state or the blocking state, so as to improve the automatic control of the air conditioner. When the flow rate of condensed water is large, the sealing component 200 is controlled to move to the avoidance position to discharge part or all of the condensed water, and then the sealing component 200 is controlled to move to the blocking position to seal the drainage outlet.

[0030] Please refer to Figures 1 to 6The present invention further provides a drainage device, which is arranged on a water receiving tray 100, and a drainage port 110 is arranged on the water receiving tray 100. The drainage device includes: a sealing component 200, which is opposite to the drainage port 110, and the position of the sealing component 200 is movably arranged to block or avoid the drainage port 110; a sealing space 210 is arranged on the sealing component 200, and a sealing cavity 220 is formed between the sealing space 210 and the water receiving tray 100, so that the sealing component 200 is in a blocking position to block the drainage port 110; wherein, at least a part of the sealing component 200 can be elastically arranged to compress the sealing cavity 220, and push the fluid in the sealing cavity 220 into the drainage port 110 for discharge.

[0031] According to the drainage device provided in the present application, it is arranged on a water receiving tray 100, and a drain outlet 110 is arranged on the water receiving tray 100. The device includes: a sealing component 200, which is opposite to the drain outlet 110, and the position of the sealing component 200 is movably arranged to block or avoid the drain outlet 110; a sealing space 210 is arranged on the sealing component 200, and a sealing cavity 220 is formed between the sealing space 210 and the water receiving tray 100, so that the sealing component 200 is in a blocking position to block the drain outlet 110; wherein, at least a part of the sealing component 200 can be elastically arranged to compress the sealing cavity 220, so as to push the fluid in the sealing cavity 220 into the drain outlet 110 for discharge. Such an arrangement can control the drain outlet 110 to be in a sealed state or a drain state through the sealing component 200. 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 an avoidance position. At the same time, when in the blocking position, the sealing component 200 is squeezed to deform so as to push the fluid in the sealed cavity 220 into the drain outlet 110 for discharge. This can speed up the discharge of the fluid. At the same time, the fluid oscillation caused by the repeated movement of the sealing component 200 can be used to discharge the dirty impurities in the fluid along with the fluid from the drain outlet 110.

[0032] In the drainage device provided in the present application, the sealing component 200 includes three states, namely, an avoidance position for avoiding the drain outlet 110, at which the drain outlet 110 is open and condensed water is discharged from the drain outlet 110 autonomously; a blocking position for blocking the drain outlet 110, at which the drain outlet 110 is sealed by the sealing cavity 220 to prevent condensed water from being discharged; the sealing component 200 repeatedly moves between the blocking position and the avoidance position, and at the same time, the sealing component 200 is squeezed when in the blocking position, at which time the sealing component 200 is used to increase the discharge speed of condensed water, and the sealing component 200 vibrates the condensed water during the repeated movement, so that the deposited dirt and impurities can float in the condensed water, and the discharge of the condensed water and the dirt mixture is accelerated by compressing the sealing cavity 220.

[0033] In the embodiment provided in the present application, the sealing component 200 extends along a predetermined arc track to enclose a sealed space 210; the sealing component 200 is covered on the drain outlet 110 and fits with the water receiving tray 100 to be in a blocking position. Preferably, the sealing component 200 is a hemispherical structure, which can maintain a good fit with the water receiving tray 100. At the same time, compared with the sealing component 200 being a prismatic structure, it avoids the generation of angles on the sealing component 200, which is prone to stress concentration when the sealing component 200 is deformed, thereby reducing the 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 component 200, at least part of which is movably arranged to drive the sealing component 200 to move; wherein, after the power assembly 300 drives the sealing component 200 to move to the blocking position, the power assembly 300 continues to move, so as to squeeze the sealing component 200, so that the sealing component 200 is in a squeezed state, so as to compress the sealing cavity 220. Such an arrangement can utilize the power assembly 300 to drive the sealing component 200 to move, thereby controlling the moving position of the sealing component 200, and realizing the switching of the sealing component 200 between different positions.

[0036] Furthermore, the power assembly 300 includes: a telescopic component 310, which is connected to the sealing component 200, and the telescopic component 310 is telescopically arranged in the vertical direction, and the sealing component 200 is driven to move or squeeze the sealing component 200 by the telescopic component 310; a driving component 320, which is connected to the telescopic component 310 and is used to drive the telescopic component 310 to telescope. Preferably, the driving component 320 is a cylinder, the telescopic component 310 is a piston rod, or the telescopic component 310 is a hydraulic rod. The structure set in this way is simple and easy to implement, and the sealing component 200 is controlled by cylinder drive or hydraulic drive. When the user selects the drainage mode, the telescopic component contracts to realize drainage of the drain outlet, and when the user selects the non-drainage mode, the telescopic component stretches to realize sealing of the drain outlet.

[0037] In order to protect the power assembly 300, the drainage device further includes: a protection box body 400, which is covered on the power assembly 300 and connected to the power assembly 300, and a wire hole 410 is provided on the protection box body 400, and the connecting wire of the power assembly 300 passes through the wire hole 410 to connect with the power supply; and a avoidance opening 420 is also provided on the protection box body 400, and a avoidance channel for avoiding the fluid is formed between the avoidance opening 420 and the water receiving tray 100, and the fluid in the water receiving tray 100 flows into the drain port 110 through the avoidance channel. Preferably, there are multiple avoidance openings 420, and the multiple avoidance openings 420 are arranged at intervals along the circumference of the protection box body 400, and there is a mounting portion between two adjacent avoidance openings 420, and the protection box body 400 is connected to the water receiving tray 100 through the mounting portion, so that the fixing of the protection box body 400 is achieved, and the avoidance opening 420 is used to provide an avoidance channel for condensed water.

[0038] In specific implementation, Figure 1 As shown, the drainage device further includes: a liquid level detection component 500, which is arranged in the water receiving tray 100 to detect the liquid flow in the water receiving tray 100; the liquid level detection component 500 is connected to the power component 300 by signal, and the power component 300 drives the sealing component 200 to be in the avoidance position, the blocking position or the extrusion state according to the detection result of the liquid level detection component 500. Preferably, the liquid level detection component 500 is a liquid level sensor. By setting the liquid level detection component 500, the liquid level of the condensed water is monitored in real time. When the liquid level of the condensed water reaches the first upper limit position, the signal is transmitted to the power component 300, and the power component 300 controls the sealing component 200 to move to the avoidance position, so that the drain port 110 is opened and the condensed water is discharged; when the liquid level of the condensed water reaches the second upper limit position, the signal is transmitted to the power component 300, and the power component 300 controls the sealing component 200 to move repeatedly between the blocking position and the sealing position, and squeezes the sealing component 200 at the same time to achieve rapid discharge of the condensed water; when the liquid level of the condensed water reaches the third position, the liquid level detection component 500 transmits a signal to the power component 300, and the power component 300 controls the sealing component 200 to move to the blocking position to seal the drain port 110. Among them, the second upper limit position is higher than the first upper line position. The third position is lower than the second upper limit position.

[0039] In order to make the sealing component 200 fit more closely with the water receiving tray 100 and limit the sealing component 200, a groove 120 is also provided on the water receiving tray 100, and the groove 120 is arranged around the drain port 110; at least part of the sealing component 200 fits with the groove wall of the groove 120, so that the sealing component 200 is in a blocking position. Since there is always condensed water in the water receiving tray 100, the sealing component 200 is prone to slipping during the process of repeatedly fitting the sealing component 200 with the water receiving tray 100. The sealing component 200 is limited by the groove 120, so that the sealing component 200 always fits on the groove wall of the groove 120, thereby optimizing the sealing effect.

[0040] Further, the water receiving tray 100 is provided with a confluence body 130, and the drain port 110 is provided on the confluence body 130; the drainage device further comprises: a drain pipe 600, the end of the drain pipe 600 is provided with a clamping groove 610, the clamping groove 610 extends along the circumferential direction of the drain pipe 600, and the body of the confluence body 130 surrounding the drain port 110 is clamped in the clamping groove 610, so that the drain port 110 is connected with the drain pipe 600; wherein the drain pipe 600 and the confluence body 130 are interference fit. Such a setting can improve the tightness of the fit between the drain pipe 600 and the confluence body 130, preferably, the surface of the confluence body 130 is lower than the surface of the water receiving tray 100, so that the condensed water in the water receiving tray 100 can be converged into the confluence body 130, and then discharged through the drain port 110.

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

[0042] The drainage device of the present invention seals and opens the drainage port of the product through a movable seal (the sealing component 200 mentioned above), and controls the movement of the seal to enable the user to select a drainage mode and a non-drainage mode (sealing mode), thereby facilitating the user to select a high-performance energy-saving state and a relatively low-performance state. Through a bowl-shaped seal, the edge of the bowl is set on the drainage port and fits in place, and the deformation and compression of the bowl-shaped seal are used to pressurize the drainage port and the inner cavity of the water pipe, thereby achieving the effect of discharging dirt such as sludge. Through water level detection (liquid level detection component) and control of the drainage device, the accumulated water is concentratedly drained after accumulating to a certain height, thereby achieving a large amount of water flushing to remove dirt and blockages, thereby achieving the sewage cleaning function in the machine body.

[0043] The seal fits tightly against and can seal the drain outlet, the drain pipe is installed at the drain outlet, the telescopic member (the telescopic member 310) is connected to the seal, and the telescopic member and the detection member are installed on the installation member. The device can control the blocking of the drain outlet through the telescopic seal, solving the problem that commonly used sealing valves are easily blocked by dirt. The bowl-shaped seal is deformed to increase the pressure at the drain outlet, so that dirt in the drain pipe can be discharged.

[0044] like Figure 3 As shown, when the seal is at position t0, the drain port can be sealed. Figure 5 As shown, when the seal is at position t1, drainage can be achieved at the drain port, and when the seal is at position t2, the drain pipe can be pressurized and internal dirt can be discharged. In order to achieve continuous position change of the seal to achieve continuous pressurization and sewage discharge.

[0045] When the water level reaches a certain height, the detection part receives the signal and makes a judgment, and the telescopic part drives the seal to continuously pull and expand, and the condensed water in the water tank is driven to vibrate through the vibration. Under the flow and impact of the condensed water, the dirt in the water tank can be suspended in the condensed water and flow into the drain pipe under the action of the water flow. At the same time, because the seal also pressurizes the drain port, it can achieve faster sewage discharge and greater impact sewage discharge.

[0046] like Figure 7 As shown, when the sewage discharge function is set, the drainage device is controlled to enter a non-drainage state. By controlling the indoor and outdoor motors, the indoor and outdoor fan blades are set to run at a set speed, generally a lower speed indoors and a higher speed outdoors, and the compressor enters a set frequency, generally a higher frequency and high load operation, so that the product can generate a large amount of condensed water at a faster speed. The detection part of the drainage device detects that the water level has reached the set height, and then controls the telescopic part to drive the sealing part to continuously telescope at positions t1 and t2 and continuously pressurize the drainage pipe, so that the running water drives the dirt to be discharged. The above is a P cycle. After multiple P cycles, the dirt in the product has been discharged.

[0047] This application realizes the user-selectable drainage mode and non-drainage mode operation, avoids the complex disassembly and assembly of the product, and simplifies the existing water collection box installation steps, etc. At the same time, it solves the problem that the sink and drain pipe are easily dirty and blocked due to long-term use of the product, verifies the service life and reduces after-sales maintenance.

[0048] In this application, the telescopic member and the sealing member can be replaced by an electronic sealing valve design, but because there is a lot of dirt in the water, the service life of the electronic sealing valve material will be reduced. And the electronic sealing valve itself is easily blocked by dirt.

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

[0050] like Figure 6 As shown, the present invention further provides an air conditioner, comprising a body and a drainage device 800, wherein the drainage device 800 is arranged in the body, and the drainage device 800 is the above-mentioned drainage device.

[0051] The air conditioner also includes a compressor 710, an outdoor heat exchanger 720, a fan blade 730, a water 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 arranged in the compressor chamber and is connected to the outdoor heat exchanger 720. The water ring 740 is arranged on the fan blade 730. The water ring 740 rotates with the fan blade 730 to pump condensed water onto the outdoor heat exchanger 720 to cool it. The drainage device 800 is arranged in the heat exchange chamber.

[0052] The window type air conditioner with the drainage device of the present invention has a drainage port arranged on the outdoor side, and the drainage device is arranged at the drainage port position. When the sewage discharge function is turned on, the window type air conditioner enters the sewage discharge method, and the condensed water is rapidly precipitated by setting the wind speed, the compressor frequency, etc. The water level height is detected by the detection part of the drainage device to reach the specified height, and the sealing part position is controlled to realize drainage, thereby realizing the discharge of a large amount of accumulated water, thereby realizing the cleaning of the dirt inside the machine and realizing the sewage discharge function.

[0053] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0054] According to the drainage device provided in the present application, it is arranged on a water receiving tray 100, and a drain outlet 110 is arranged on the water receiving tray 100. The device includes: a sealing component 200, which is opposite to the drain outlet 110, and the position of the sealing component 200 is movably arranged to block or avoid the drain outlet 110; a sealing space 210 is arranged on the sealing component 200, and a sealing cavity 220 is formed between the sealing space 210 and the water receiving tray 100, so that the sealing component 200 is in a blocking position to block the drain outlet 110; wherein, at least a part of the sealing component 200 can be elastically arranged to compress the sealing cavity 220, so as to push the fluid in the sealing cavity 220 into the drain outlet 110 for discharge. Such an arrangement can control the drain outlet 110 to be in a sealed state or a drain state through the sealing component 200. 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 an avoidance position. At the same time, when in the blocking position, the sealing component 200 is squeezed to deform so as to push the fluid in the sealed cavity 220 into the drain outlet 110 for discharge. This can speed up the discharge of the fluid. At the same time, the fluid oscillation caused by the repeated movement of the sealing component 200 can be used to discharge the dirty impurities in the fluid along with the fluid from the drain outlet 110.

[0055] The invention solves the problem that after installing the window air conditioner, the user cannot easily switch between the drainage state and the non-drainage state, and it is inconvenient for the user to select the high-efficiency water-pumping mode and the ordinary non-water-pumping mode.

[0056] The invention solves the problem that when users install a window air conditioner, they need to remove the rubber plug and install the drainage box and water pipe, which is complicated and simplifies the installation.

[0057] It solves the problem that after long-term use of the product, dirt such as sludge accumulates in the condensate water path, causing the water path to become dirty and blocked, resulting in corrosion and damage that reduces the product's service life, and odor problems.

[0058] It solves the problem of slow or impossible drainage due to dirty water channels and pipes, resulting in leakage and dripping.
