Description

Technical Field

[0001] The present application relates to the field of air conditioning, and in particular to a drainage treatment device and a drainage treatment method thereof, and an air conditioner. Background Art

[0002] With rising living standards, air conditioning has become an essential necessity, especially during hot summers, when cooling demand for wall-mounted air conditioners is even greater. During cooling operation, the evaporator exchanges heat with the hot air, causing water vapor in the air to condense and form condensed water. However, this condensed water cannot be fully drained from the unit, and a significant amount of it remains, breeding grounds for bacteria and other microorganisms trapped in the dust, leading to mold. Deep cleaning is difficult for users to do themselves, and poses a health risk. Summary of the Invention

[0003] The purpose of the present application is to provide a drainage treatment device and a drainage treatment method thereof, as well as an air conditioner, which can provide a buffer space for liquid while preventing liquid from accumulating inside and avoiding blockage.

[0004] To this end, in a first aspect, an embodiment of the present application provides a drainage treatment device for an air conditioner, the drainage treatment device comprising:

[0005] The housing has a receiving cavity for carrying liquid, the housing has a water receiving bottom plate and a first recess and a second recess that are recessed relative to the water receiving bottom plate, the bottom walls of the first recess and the second recess are respectively provided with a first drain port and a second drain port,

[0006] a blocking portion, provided at the first drain outlet, for blocking the first drain outlet;

[0007] The mobile platform has a first surface, which is sealed and connected to the first recess. The mobile platform can move relative to the first recess. In an initial state, the first surface is flush with the surface of the water receiving bottom tray.

[0008] In the cooling state, when the amount of condensed liquid is greater than or equal to the drainage volume of the second drain port, the liquid accumulates in the water receiving base, and under the action of the gravity of the liquid, the mobile platform moves toward the direction close to the first drain port. The first surface and the first recess form a buffer space for caching the liquid. When the amount of condensed liquid is less than the drainage volume of the second drain port, as the amount of accumulation of the liquid in the water receiving base decreases, the mobile platform moves away from the first drain port until it returns to the initial state.

[0009] In a possible implementation, an elastic member is further included, which is arranged between the first recess and the movable platform. Under the action of the gravity of the liquid, the elastic member can drive the movable platform to move closer to or away from the first drain outlet.

[0010] In one possible implementation, the elastic member has a preset rebound force. When the water receiving tray stores the liquid, the elastic member is compressed to form the cache space. When the water receiving tray is free of the liquid, the liquid in the cache space can be discharged under the action of the preset rebound force until the first surface is flush with the surface of the water receiving tray.

[0011] In a possible implementation, a sealing member is provided on the side wall of the mobile platform for sealing the fitting gap between the side wall and the first recess.

[0012] In a possible implementation, the second recess is provided with the movable platform, and the movable platform located in the second recess is provided with a through hole connected to the second drain port, for discharging the liquid from the second drain port.

[0013] In a possible implementation, a blockage detection member is further included, for detecting the movement of the mobile platform.

[0014] In the refrigeration state, when the blockage detection component detects that the mobile platform moves toward the first drain outlet to a preset distance, the control stops continuing to produce the liquid into the accommodating chamber to be in a drainage state, and detects the time for the mobile platform to return to the initial state. If it is greater than or equal to the first preset time, the control stops and the second drain outlet is blocked.

[0015] In a possible implementation, the blockage detection member includes a first detection portion and a second detection portion that cooperate with each other.

[0016] One of the first detection part and the second detection part is arranged on the mobile platform, and the other is arranged on the bottom wall of the first recess. The preset distance is the distance when the mobile platform moves from the initial state to the point where the first detection part and the second detection part abut against each other. When the mobile platform moves to the point where the first detection part and the second detection part abut against each other, blockage detection is triggered.

[0017] In a possible implementation, a third detection unit is further included, which is electrically connected to the first detection unit and the second detection unit. The third detection unit is arranged on the first surface or the surface of the water receiving bottom tray, and is used to detect the time it takes for the mobile platform to return to the initial state after the blockage detection is triggered.

[0018] In one possible implementation, the blockage detection component also includes a temperature detection component and a humidity detection component. When the mobile platform moves to the preset distance, the temperature detection component and the humidity detection component can detect to obtain the dew point temperature and adjust to the drainage state according to the dew point temperature.

[0019] In a second aspect, an embodiment of the present application provides an air conditioner, comprising a drainage treatment device as described above.

[0020] In a third aspect, an embodiment of the present application provides a drainage treatment method of a drainage treatment device, wherein the drainage treatment device is used for an air conditioner, and the drainage treatment device comprises:

[0021] The housing has a receiving cavity for carrying liquid, the housing has a water receiving bottom plate and a first recess and a second recess that are recessed relative to the water receiving bottom plate, the bottom walls of the first recess and the second recess are respectively provided with a first drain port and a second drain port,

[0022] a blocking portion, provided at the first drain outlet, for blocking the first drain outlet;

[0023] The mobile platform has a first surface, which is sealed and connected to the first recess. The mobile platform can move relative to the first recess. In an initial state, the first surface is flush with the surface of the water receiving bottom tray.

[0024] The air conditioner is controlled to be in a cooling state. If the amount of condensed liquid produced is greater than or equal to the drainage volume of the second drain port, the liquid accumulates in the water receiving base pan, and under the action of the gravity of the liquid, the movable platform moves toward the first drain port. The first surface and the first recess form a buffer space for caching the liquid. If the amount of condensed liquid produced is less than the drainage volume of the drain port, as the amount of liquid accumulated in the water receiving base pan decreases, the movable platform moves toward the direction away from the first drain port until it returns to the initial state.

[0025] In a possible implementation, the drainage treatment device further includes a blockage detection element, and the drainage treatment method includes:

[0026] In the refrigeration state, when the blockage detection component detects that the mobile platform moves toward the first drain outlet to a preset distance, the control stops continuing to produce the liquid into the accommodating chamber to be in a drainage state, and detects the time for the mobile platform to return to the initial state. If it is greater than or equal to the first preset time, the control stops and the second drain outlet is blocked.

[0027] In one possible implementation, the drainage treatment method specifically includes:

[0028] Controlling the air conditioner to be in a cooling state, so that the condensed liquid generated by cooling enters the accommodating cavity;

[0029] As the liquid accumulates in the water receiving bottom tray, the movable platform is pressed and moves the preset distance toward the first drain outlet, thereby triggering the blockage detection element;

[0030] Adjusting the air conditioner to a draining state;

[0031] A first time t1 is obtained in advance as the longest time for the mobile platform to return from the position where the blockage detection element is triggered to the initial state when the second drain outlet is not blocked and the second drain outlet is in the drainage state. The first preset time t is set according to the first time t1, where t>t1.

[0032] It is detected whether the mobile platform can return to the initial state within the first time t1 in the drainage state. If so, the second drainage port is not blocked.

[0033] In one possible implementation, the drainage processing method further includes: setting a second time t2, t1<t2<t, if the detected mobile platform exceeds the first time t1, but returns to the initial state within the second time t2, the second drainage outlet is semi-blocked.

[0034] In a possible implementation, if the mobile platform can return to the initial state within the first time t1 in the drainage state, the frequency of the compressor in the air conditioner is increased and the air conditioner is restarted to the cooling state.

[0035] According to the drainage treatment device and drainage treatment method provided by the embodiment of the present application, and the air conditioner, the mobile platform can automatically adjust whether the mobile platform moves relative to the first recess, and the size of the relative movement, etc., according to the difference between the amount of condensation generated and the amount of drainage. Therefore, when the liquid generated by condensation is large and cannot be discharged from the second drain port in time, the mobile platform is compressed by the weight of the liquid accumulated in the water receiving base to form a buffer space for caching the liquid and preventing the liquid from flowing out of the accommodating cavity. When the liquid generated by condensation is small and the amount of liquid accumulated in the water receiving base gradually decreases, the mobile platform can move in the opposite direction to gradually reduce the buffer space, and finally make the first surface and the water receiving base flush, so that the liquid in the buffer space and the water receiving base can eventually be discharged to the outside, avoiding residue and mold, and realizing automatic adjustment of drainage and water storage.

DETAILED DESCRIPTION

[0045] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] Figure 1 A simple structural schematic diagram of a drainage treatment device provided in an embodiment of the present application is shown. Figure 2 A simple structural schematic diagram is shown of a mobile platform 15 of a drainage treatment device provided by an embodiment of the present application moving to trigger a blockage detection member 19.

[0047] See also Figures 1 to 3 , an embodiment of the present application provides a drainage treatment device for an air conditioner, which includes at least a cooling function. When the air conditioner is in the cooling state, condensation produces a large amount of liquid. In order to enable the liquid to be effectively discharged, the air conditioner is provided with a drainage treatment device, including a shell 1, having a accommodating cavity 11 for carrying the liquid, the shell 1 having a water receiving base 12 and a first recess 14 and a second recess 13 that are concave relative to the water receiving base 12, and the bottom walls of the first recess 14 and the second recess 13 are respectively provided with a first drain port 141 and a second drain port 131. Generally, a first drain port 141 and a second drain port 131 are provided, respectively, on both sides of the air conditioner, so that one of the drain ports closer to the outside is selected for drainage according to the different directions in which the air conditioner is installed indoors. In the embodiment of the present application, taking the second drain port 131 for draining water to the outside as an example, the first drain port 141 is blocked by the blocking portion 18.

[0048] In the cooling state, the liquid generated by condensation enters the accommodating chamber 11 and drips onto the water receiving base 12. As the amount of water increases, when the second drain port 131 cannot be discharged in time, the first recess 14 and the second recess 13 are set at the corresponding drain port positions to provide a buffer space 142 when larger condensed water is generated.

[0049] At least the first recess 14 is sealedly connected to a movable platform 15. The movable platform 15 has a first surface 152 and is movable relative to the first recess 14. In its initial state, the first surface 152 is flush with the surface of the water receiving tray 12. In the cooling mode, when the amount of condensed liquid is greater than or equal to the amount discharged from the second drain port 131, the liquid accumulates in the water receiving tray 12, and the gravity of the liquid causes the movable platform 15 to move toward the first drain port 141. The first surface 152 and the first recess 14 enclose a buffer space 142 for caching the liquid. When the amount of condensed liquid is less than the amount discharged from the drain port, as the amount of liquid accumulated in the water receiving tray 12 decreases, the movable platform 15 moves away from the first drain port 141 until it returns to its initial state. The movable platform 15 can automatically adjust whether the movable platform 15 moves relative to the first recess 14, and the extent of the relative movement, based on the difference between the amount of condensed liquid and the amount of drained liquid. Therefore, when the amount of liquid generated by condensation is large and cannot be discharged from the second drain port 131 in a timely manner, the movable platform 15 is compressed by the weight of the liquid accumulated in the water receiving base 12 to form a buffer space 142 for buffering the liquid and preventing the liquid from flowing out of the accommodating chamber 11. When the amount of liquid generated by condensation is small and the amount accumulated in the water receiving base 12 gradually decreases, the movable platform 15 can move in the opposite direction to gradually reduce the buffer space 142, eventually making the first surface 152 and the water receiving base 12 flush, so that the liquid in the buffer space 142 and the water receiving base 12 can eventually be discharged to the outside, avoiding residue that may cause mold, and realizing automatic adjustment of drainage and water storage.

[0050] Optionally, an elastic member 17 is further included. The elastic member 17 is disposed between the first recess 14 and the movable platform 15 . Under the gravity of the liquid, the elastic member 17 can drive the movable platform 15 to move closer to or away from the first drain port 141 .

[0051] It is understandable that the elastic member 17 can be a spring, or it can also be a rubber that can produce elastic deformation, etc., which is not specifically limited here. The elastic member 17 provided in the embodiment of the present application is a spring, which is supported and connected by a support column. The elastic deformation ability of the spring can be adjusted as needed. After the liquid volume accumulated in the water receiving chassis 12 reaches a certain set value, its gravity can compress the spring to produce deformation, thereby forming a buffer space 142, and when there is no accumulated liquid or a small amount of accumulated liquid in the water receiving chassis 12, the spring can always maintain the mobile platform 15 in the initial state to avoid liquid residue. The specific elastic force of the spring is not specifically limited here. The spring set up by the elastic setting can prevent the liquid from remaining in the first blocked recess 14 during the discharge of condensed water, thereby avoiding mold and the generation of bacteria. At the same time, when the amount of condensed water generated is relatively large, the spring is compressed to drive the mobile platform 15 down to form a buffer space 142 that can buffer the liquid.

[0052] Specifically, the elastic member 17 has a preset resilience. When liquid is stored in the water receiving tray 12, the elastic member 17 is compressed to form a buffer space 142. When the water receiving tray 12 is empty, the preset resilience forces the liquid in the buffer space 142 to be discharged until the first surface 152 is flush with the surface of the water receiving tray 12. This prevents the problem of liquid previously stored in the buffer space 142 remaining after the liquid in the water receiving tray 12 is completely drained, preventing the spring from returning to its original position and resulting in incomplete drainage. The preset resilience is selected based on actual circumstances and is not detailed here.

[0053] In addition, the elastic member 17 is arranged along the depth direction of the first recess 14, and the two ends of the elastic member 17 are respectively connected to the lower surface of the movable platform 15 and the bottom wall of the first recess 14, and the elastic member 17 does not interfere with the first drain outlet 141. While avoiding the first drain outlet 141, it is necessary to ensure that the movable platform 15 will not be skewed during movement. A detailed description is not given here.

[0054] In an optional embodiment, a sealing member 16 is provided on the sidewall of the movable platform 15 to seal the clearance between the movable platform 15 and the first recess 14. An accommodating space is provided between the lower surface of the movable platform 15 and the first recess 14 for mounting an elastic member 17. The sealing member 16 seals the accommodating space, preventing liquid from entering the accommodating space regardless of whether the movable platform 15 is in motion, thereby preventing liquid from remaining therein.

[0055] Optionally, the sealing member 16 may be, for example, a sealing strip provided along the circumference of the movable platform 15, such that the sealing strip is located between the side wall of the movable platform 15 and the inner wall of the first recess 14. Alternatively, other sealing structures may be used, as long as they can ensure a good sealing effect and enable the movable platform 15 to reciprocate in the depth direction relative to the first recess 14 under the drive of the elastic member 17, and are not specifically limited here.

[0056] In an optional embodiment, the second recess 13 is also provided with a movable platform 15, and the movable platform 15 located in the second recess 13 is provided with a through hole 151 connected to the second drain port 131, for discharging the liquid from the second drain port 131. It can be known that before the use of the drainage treatment device, the movable platforms 15 located in the first recess 14 and the second recess 13 are not provided with a through hole 151. In actual installation, after selecting a suitable drain port according to actual conditions, the other drain port is blocked, and the movable platform 15 used as the drain port is provided with a through hole 151. Alternatively, through holes 151 can also be provided on both movable platforms 15, and the corresponding through holes 151 are blocked at the same time as the corresponding drain ports are blocked by the blocking portion 18. While allowing the liquid to be discharged smoothly, the same principle is used to enable the movable platform 15 to move to form a buffer space 142, thereby realizing the functions of automatic drainage and water storage, and providing a larger buffer space 142. Detailed description will not be given here.

[0057] In an optional embodiment, a blockage detection member 19 is further included for detecting the movement of the mobile platform 15. It can be understood that when the first recess 14 and the second recess 13 are both provided with the mobile platform 15, the blockage detection member 19 can be selected to be set in either one or both, and the two groups of data can be compared to avoid false detection. No specific limitation is made here. The following detailed description is given by taking the example of setting the blockage detection member 19 on one side of the blocked first recess, and no separate emphasis will be given later.

[0058] In the cooling state, when the blockage detection member 19 detects that the movable platform 15 has moved a predetermined distance toward the first drain port 141, the system stops producing liquid into the accommodating chamber 11, thereby entering a draining state. The system then detects the time it takes for the movable platform 15 to return to its initial state. If this time is greater than or equal to a predetermined time, the system stops producing liquid and the second drain port 131 becomes blocked. The blockage detection member 19 can detect whether the second drain port 131 is blocked, thereby preventing excess liquid from overflowing from the accommodating chamber 11 and causing financial loss to the user.

[0059] Optionally, the blockage detection member 19 includes a matching first detection portion 191 and a second detection portion 192, one of the first detection portion 191 and the second detection portion 192 is arranged on the mobile platform 15, and the other is arranged on the bottom wall of the first recess. The preset distance is the distance when the mobile platform 15 moves from the initial state to the abutment between the first detection portion 191 and the second detection portion 192. When the mobile platform 15 moves to the abutment between the first detection portion 191 and the second detection portion 192, the blockage detection is triggered.

[0060] The system also includes a third detection unit electrically connected to the first and second detection units. The third detection unit is disposed on the first surface or the surface of the water receiving tray and is configured to detect the time it takes for the mobile platform to return to its initial state after a blockage detection is triggered. The detected return time is compared with a first preset time to determine whether the second drain outlet is blocked, thereby ensuring detection accuracy.

[0061] In an optional embodiment, the blockage detection component 19 also includes a temperature detection component and a humidity detection component. When the mobile platform 15 moves to a preset distance, the temperature detection component and the humidity detection component can detect to obtain the dew point temperature and adjust to the drainage state according to the dew point temperature.

[0062] The embodiment of the present application also provides an air conditioner, including the drainage treatment device as described above, which will not be repeated here.

[0063] The present application also provides a drainage treatment method for a drainage treatment device used in an air conditioner. The drainage treatment device is the same as the drainage treatment device described above and will not be described in detail. The drainage treatment method is described in detail below, using the example of a first drain port being blocked, a second drain port being used for drainage, and a first recess and a second recess both being provided with a movable platform.

[0064] See also Figures 4 to 6 , an embodiment of the present application provides a drainage treatment method, comprising:

[0065] S100. Control the air conditioner to be in a cooling state. If the amount of condensed liquid generated is greater than or equal to the drainage volume of the second drain port, the liquid accumulates in the water receiving chassis, and under the action of the gravity of the liquid, the movable platform moves toward the direction close to the first drain port. The first surface and the first recess enclose a buffer space for caching the liquid. If the amount of condensed liquid generated is less than the drainage volume of the first drain port, as the amount of liquid accumulated in the water receiving chassis decreases, the movable platform moves toward the direction away from the first drain port until it returns to its initial state.

[0066] The mobile platform automatically adjusts its relative movement based on the amount of condensed water and the amount of water drained. When the amount of condensed liquid is too large to be drained promptly from the second drain port, the mobile platform utilizes the weight of the liquid accumulated in the water receiving tray to create a buffer space for the liquid, preventing it from flowing out of the accommodating chamber. When the amount of condensed water decreases and the amount of liquid accumulated in the water receiving tray gradually decreases, the mobile platform reverses its motion, gradually reducing the buffer space, ultimately aligning the first surface with the water receiving tray. This allows the liquid in both the buffer space and the tray to drain to the outside, preventing any residual liquid from causing mold, thereby achieving automatic adjustment of drainage and water storage.

[0067] In an optional embodiment, the drainage treatment device further includes a blockage detection element, and the drainage treatment method includes:

[0068] S200. In the cooling state, when the blockage detection component detects that the mobile platform moves toward the first drain outlet to a preset distance, the control stops the continued generation of liquid into the accommodating chamber to be in a drainage state, and detects the time it takes for the mobile platform to return to the initial state. If it is greater than or equal to the first preset time, the control stops and the second drain outlet is blocked.

[0069] The blockage detection member can detect whether the second drain outlet is blocked, thereby preventing excessive liquid buffered in the accommodating chamber from overflowing and causing damage to the air conditioner.

[0070] Specifically, the drainage treatment methods include:

[0071] S201: Control the air conditioner to be in a cooling state, and condensed liquid generated by cooling enters the accommodating cavity.

[0072] S202: As liquid accumulates in the water receiving bottom tray, the mobile platform is pressed to move a preset distance toward the first drain outlet, triggering the blockage detection element.

[0073] S203: Adjust the air conditioner to the drainage state.

[0074] S204, pre-acquire the first time t1, which is the longest time for the mobile platform to return from the position of triggering the blockage detection component to the initial state when the second drain outlet is not blocked and is in the drainage state, and set the first preset time t according to the first time t1, t>t1.

[0075] S205: Check whether the mobile platform can return to the initial state within the first time t1 in the drainage state. If so, the second drainage outlet is not blocked.

[0076] Optionally, adjusting the air conditioner to the drainage state includes detecting the ambient temperature, humidity, etc. at the moment when the blockage detection component is triggered, and determining the dew point temperature at which no condensation water will be generated based on the specific situation. The inner tube temperature is adjusted to be greater than the dew point temperature, so that the air conditioner can be adjusted to the drainage state without generating condensation water.

[0077] Specifically, when the air conditioner is in the cooling state, the mobile platform moves downward under the action of accumulated condensed water to form a buffer space for caching liquid. When the mobile platform moves to the position that triggers the blockage detection element, it detects the temperature and humidity of the environment at that moment to obtain the dew point temperature. The temperature of the air conditioner's internal pipe is adjusted to be greater than the dew point temperature, so that water vapor in the air does not condense into water when it encounters the evaporator, thus entering the drainage state. At the same time, a timer is started to obtain the time it takes for the mobile platform to return to the initial state from that moment. This time is compared with the first time t1, the second time t2, and the first preset time t. If it is less than the first time t1, it indicates that the second drain outlet can drain liquid within the maximum allowed time and the second drain outlet is not blocked. It is only because the amount of condensed water generated by the second drain outlet is unable to drain in time. If it is greater than the first time t1 but not greater than the second time t2, it indicates that the second drain outlet is blocked but not completely. If it is greater than the first preset time t, it indicates that the second drain outlet is completely blocked and needs to be immediately shut down and cleaned to prevent liquid overflow.

[0078] It can be understood that the set first time t1, second time t2 and first preset time t are data pre-set according to the situation, and are obtained comprehensively based on the size of the drain outlet, the amount of condensed water generated, etc., and are not specifically limited here.

[0079] In an optional embodiment, the drainage processing method further includes setting a second time t2, where t1 < t2 < t. If the detected mobile platform exceeds the first time t1 but returns to its initial state within the second time t2, the second drain outlet is semi-blocked. In this state, a semi-blocked warning may be issued to the user, but the air conditioner can still operate in cooling mode. The warning disappears after the user clears the blockage. Alternatively, the compressor frequency may be reduced, the expansion valve opening may be decreased, and the internal pipe temperature may be set above the dew point to prevent condensation. This also reminds the user of the blockage and prompts them to clear it immediately.

[0080] Alternatively, if the mobile platform can return to its initial state within the first time t1 while draining, the compressor frequency of the air conditioner can be increased and the air conditioner can be restarted to the cooling state. If the second drain port is determined to be unblocked, this indicates that the second drain port is unable to drain the liquid in a timely manner due to a large amount of condensed water. In this case, the compressor frequency and expansion valve opening can be increased to resume normal cooling operation.

[0081] It should be emphasized that the above-mentioned drainage treatment device and drainage treatment method can be applied to air conditioners, and can also be applied to other equipment with cooling and drainage requirements, and no specific limitation is made here.
