Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically providing a drainage control device and a drainage control method. Background Technology

[0002] During the operation of a portable air conditioner, the condensate produced by the evaporator will be stored in the water storage pan and needs to be drained in time. Currently, the common method is to install a water pump motor on the chassis to pump some water onto the condenser. The condenser dissipates heat while solving the problem of draining some water. Then, a sensor will remind you to alarm when the water is full, and the accumulated water will be emptied manually.

[0003] The alarm may be inaccurate when the water is full because the water wheel will raise the water level during operation. When it stops, the water level will actually be lower than when the alarm was triggered, resulting in wasted space. This may lead to frequent start-stop situations and excessive manual operation.

[0004] Therefore, there is an urgent need in this field for a new drainage control solution to address the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem of false alarms caused by water level errors.

[0006] In a first aspect, the present invention provides a drainage control device. The drainage control device includes a water storage pan, a water pumping device, a float device, and a partition wall. The water storage pan is used to hold condensate from the portable air conditioner. The water pumping device is disposed on one side of the water storage pan and is used to pump the condensate onto the condenser. The float device is disposed on the other side of the water storage pan and is used to detect the water level around the float device. The partition wall is disposed between the water pumping device and the float device and has a first through hole. Condensate from the water pumping device side enters the float device side through the first through hole to prevent water level fluctuations on the float device side caused by the operation of the water pumping device.

[0007] In the preferred embodiment of the above-mentioned drainage control device, a plurality of first through holes are evenly distributed on the partition wall. The height of the partition wall is higher than the height of the water pumped by the water pumping device, so as to prevent the pumped water from passing over the partition wall and entering the float device side.

[0008] In the preferred embodiment of the above-mentioned drainage control device, the drainage control device further includes a water storage tank located on the opposite side of the rotation of the water pumping device, in order to store water in the water storage pan and further reduce water level fluctuations on the float device side.

[0009] In the preferred embodiment of the above-mentioned drainage control device, the water storage tank includes a first pool wall and a second pool wall connected together. The first pool wall is higher than the second pool wall. Water in the water storage pan enters the water storage tank through the second pool wall. A second through hole is provided on the first pool wall to allow water in the water storage tank to be introduced into the float device side.

[0010] In the preferred embodiment of the above-mentioned drainage control device, a plurality of second through holes are evenly distributed on the first pool wall.

[0011] In the preferred embodiment of the above-mentioned drainage control device, the water pumping device includes a water pumping motor and a water pumping wheel, and the output shaft of the water pumping motor is connected to the water pumping wheel to drive the water pumping wheel to rotate.

[0012] In a preferred embodiment of the above-mentioned drainage control device, the drainage control device further includes a controller and a first water level sensor, a second water level sensor, and a third water level sensor that are communicatively connected to the controller. The first water level sensor is disposed on the partition wall and is used to detect a first water level value between the partition wall and the water impeller. The second water level sensor is disposed on the inner wall of the water storage tank and is used to detect a second water level value in the water storage tank. The third water level sensor is disposed on the float device and is used to detect a third water level value around the float device.

[0013] In the preferred embodiment of the above-mentioned drainage control device, the drainage control device further includes an alarm connected to the controller to trigger an alarm when the third water level value meets the requirements.

[0014] In a second aspect, the present invention provides a drainage control method. The drainage control method employs the aforementioned drainage control device. The drainage control method includes: after the portable air conditioner is started, the water storage pan begins to receive condensate; when a first water level value detected by the first water level sensor is greater than a first preset water level value stored in the controller, the water pump is activated to operate at low speed; when a second water level value detected by the second water level sensor is greater than a second preset water level value stored in the controller, the water pump is activated to operate at high speed; and when a third water level value detected by the third water level sensor is greater than a third preset water level value stored in the controller, an alarm is activated.

[0015] In a preferred embodiment of the above-mentioned drainage control method, the drainage control method further includes switching the water impeller to low-speed operation after the water impeller has been running at high speed and the second water level value drops below the second preset water level value.

[0016] When the above technical solution is adopted, the drainage control device of the present invention uses a partition wall to separate the float device and the water pumping device, and by opening a first through hole in the partition wall, it prevents the water level on the float device side from floating due to the operation of the water pumping device.

[0017] The drainage control device in this invention also includes a water storage tank, which comprises a first tank wall and a second tank wall of different heights. The lower second tank wall introduces water from the storage pan into the water storage tank, while the higher first tank wall has a second through hole to further reduce water level fluctuations on the float device side caused by the operation of the water pumping device. This avoids water level errors when the water is full, making the alarm of the float device more accurate and reducing the frequency of manual operation.

[0018] This invention also includes a first water level sensor to detect the first water level between the partition wall and the water impeller, a second water level sensor to detect the second water level in the reservoir, and a third water level sensor to detect the third water level around the float device. This achieves precise monitoring of water levels. Attached Figure Description

[0030] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] Reference Figures 1 to 2 , Figure 1 This is a schematic diagram of an embodiment of the drainage control device of the present invention. Figure 2 This is another schematic diagram of an embodiment of the drainage control device of the present invention.

[0032] like Figures 1 to 2 As shown, the drainage control device of this embodiment is used for a portable air conditioner. The drainage control device includes: a water storage pan 1, a water pumping device 2, a float device 3, and a partition wall 4; the water storage pan 1 is used to hold the condensate water of the portable air conditioner; the water pumping device 2 is disposed on one side of the water storage pan 1 and is used to pump the condensate water onto the condenser; the float device 3 is disposed on the other side of the water storage pan 1 and is used to detect the water level around the float device 3; the partition wall 4 is disposed between the water pumping device 2 and the float device 3, and has a first through hole 41; wherein, the condensate water on the water pumping device side enters the float device side through the first through hole 41 to prevent the water level on the float device side from floating due to the operation of the water pumping device 2.

[0033] Specifically, the water storage pan 1 can be a hollow water-holding device such as a disc or box. The water-dispensing device 2 can be fixed to one side wall of the water storage pan 1. The float device 3 is fixed to the bottom wall of the water storage pan 1 and must maintain a certain distance from the water-dispensing device 2. The float device 3 and the water-dispensing device 2 are separated by a partition wall 4. The partition wall 4 has a first through hole 41 that allows passage between the two sides. For example, the float device 3 can be located on the left side of the water storage pan 1, and the water-dispensing device 2 can be located on the opposite left or the diagonally opposite right side, and the two must be separated by the partition wall 4. The top of the float device 3 is lower than the top of the side wall of the water storage pan 1.

[0034] In addition to maintaining communication between the water-pumping device side and the float device side through the first through-hole 41, a certain distance can be maintained between the side of the partition wall 4 away from the water-pumping device 2 and the side wall of the water storage pan 1 on that side, so that the water pumped by the water-pumping device 2 can flow through this distance into the float device side. This increases the water flow channel, maintaining the stability of the water flow on the float device side, while also reducing the water flow pressure that is only connected through the first through-hole 41.

[0035] In a preferred embodiment of the present invention, a plurality of first through holes 41 are uniformly distributed on the partition wall 4.

[0036] Specifically, in order to reduce the impact of water flow, a number of first through holes 41 are evenly distributed on the partition wall 4, for example, they can be arranged in rows, preferably in three rows.

[0037] Preferably, the first through hole 41 located at the lowest position of the partition wall 4 is higher than the bottom wall of the water storage pan 1.

[0038] In a preferred embodiment of the present invention, the height of the partition wall 4 is higher than the height of the water pumped by the water pumping device 2, so as to prevent the pumped water from passing over the partition wall 4 and entering the float device side.

[0039] Specifically, the height of the partition wall 4 is preferably flush with the side wall of the water storage pan 1. This ensures that the installation is not affected and that the water pumped up does not cross the partition wall 4 and enter the float device side.

[0040] In a preferred embodiment of the present invention, the drainage control device further includes a water storage tank 5, which is located on the opposite side of the rotation of the water pumping device 2, to store part of the water in the water storage pan 1 and further reduce the water level fluctuation on the float device side.

[0041] Specifically, the water storage tank 5 can be located on the right side of the water storage pan 1, and the water pumping device 2 and the float device 3 are both located near the water storage tank 5, and the water pumped by the rotation of the water pumping device 2 flows to the opposite side of the water storage tank 5.

[0042] In a preferred embodiment of the present invention, the water storage tank 5 includes a first tank wall 51 and a second tank wall 52 connected together. The first tank wall 51 is higher than the second tank wall 52. Water in the water storage pan 1 enters the water storage tank 5 through the second tank wall 52. A second through hole 53 is provided on the first tank wall 51 to allow water in the water storage tank 5 to be introduced into the float device side.

[0043] Specifically, water from the storage pan 1 is introduced into the reservoir 5 through the lower second pool wall 52. Preferably, the height of the second pool wall 52 is half the height of the side wall of the storage pan 1. The second through hole 53 on the first pool wall 51 has a similar function to the first through hole 41, allowing water in the reservoir 5 to slowly enter the float device side.

[0044] In a preferred embodiment of the present invention, a plurality of second through holes 53 are uniformly distributed on the first pool wall 51.

[0045] Specifically, the multiple second through holes 53 can reduce the impact of water flow. The multiple second through holes 53 can be arranged in rows, preferably in three rows.

[0046] Preferably, the second through hole 53 located at the lowest position of the first pool wall 51 is higher than the bottom wall of the water storage pan 1.

[0047] In a preferred embodiment of the present invention, the water pumping device 2 includes a water pumping motor 21 and a water pumping wheel 22. The output shaft of the water pumping motor 21 is connected to the water pumping wheel 22 to drive the water pumping wheel 22 to rotate.

[0048] Specifically, the water pump motor 21 is located on the outer side of the side wall of the water storage pan 1, and the water pump wheel 22 is located on the inner side of the side wall of the water storage pan 1 and is connected to the output shaft of the water pump motor 21.

[0049] Preferably, the minimum distance between the partition wall 4 and the water impeller 22 is the same as the distance between the water impeller 22 and the side wall of the water storage pan 1.

[0050] In a preferred embodiment of the present invention, the drainage control device further includes a controller and a first water level sensor, a second water level sensor, and a third water level sensor connected to the controller via communication. The first water level sensor is mounted on the partition wall 4 to detect the first water level value between the partition wall 4 and the water impeller 22. The second water level sensor is mounted on the inner wall of the reservoir 5 to detect the second water level value within the reservoir 5. The third water level sensor is mounted on the float device 3 to detect the third water level value around the float device 3.

[0051] Specifically, during the water rise process, some of the water accumulated on the pump side is stored in the reservoir 5 through the second wall 52, while some flows relatively gently into the float device side through the perforated partition wall 4. Due to the obstruction of the partition wall 4, the water level on the float device side is relatively error-free after the pump 22 stops operating. Furthermore, the third water level value is greater than the second water level value, which in turn is greater than the first water level value.

[0052] In a preferred embodiment of the present invention, the drainage control device further includes an alarm connected to the controller for triggering an alarm when the third water level value meets the requirements.

[0053] Specifically, when the water level around the float device 3, that is, the third water level value, reaches the requirement of being full, the alarm will sound.

[0054] The drainage control device of the present invention uses a partition wall 4 to separate the float device 3 and the water pumping device 2, and prevents the water level on the float device side from floating due to the operation of the water pumping device 2 by opening a first through hole 41 on the partition wall 4.

[0055] In this invention, the drainage control device also includes a water storage tank 5, which comprises a first tank wall 51 and a second tank wall 52 of different heights. The lower second tank wall 52 introduces water from the water storage pan 1 into the water storage tank 5. A second through hole 53 is provided on the higher first tank wall 51 to further reduce water level fluctuations on the float device side caused by the operation of the water pumping device 2. This avoids water level errors when the water is full and makes the alarm of the float device 3 more accurate, reducing the frequency of manual operation.

[0056] This invention also includes a first water level sensor to detect the first water level between the partition wall 4 and the water impeller 22, a second water level sensor to detect the second water level in the reservoir 5, and a third water level sensor to detect the third water level around the float device 3. This achieves precise monitoring of water levels.

[0057] Reference Figures 3 to 4 , Figure 3 This is a flowchart of an embodiment of the drainage control method of the present invention. Figure 4 This is another flowchart of an embodiment of the drainage control method of the present invention.

[0058] like Figures 3 to 4 As shown, the drainage control method of this embodiment uses the aforementioned drainage control device, and the drainage control method includes the following steps S101-S104.

[0059] Step S101: After the portable air conditioner is started, the water storage tray 1 begins to receive condensate.

[0060] Specifically, once the portable air conditioner is turned on, its evaporator will generate condensate in real time and store it in the water storage pan 1.

[0061] Step S102: When the first water level value detected by the first water level sensor is greater than the first preset water level value stored in the controller, the water turbine 22 is started to run at low speed.

[0062] Specifically, the first preset water level value is stored in the controller. The controller can communicate with the first water level sensor in real time to obtain the detected first water level value and compare it with the internally stored first preset water level value. Preferably, the first preset water level value is the water level on the impeller side reaching half the height of the impeller 22.

[0063] Step S103: When the second water level value detected by the second water level sensor is greater than the second preset water level value stored in the controller, the water turbine 22 is started to run at high speed, wherein the second preset water level value is greater than the first preset water level value.

[0064] Specifically, the second preset water level value is also stored in the controller. The controller can communicate with the second water level sensor in real time to obtain the detected second water level value and compare it with the internally stored second preset water level value. Preferably, the second preset water level value is the water level in the reservoir 5 when it reaches the top of the second pool wall 52.

[0065] Step S104: When the third water level value detected by the third water level sensor is greater than the third preset water level value stored in the controller, the alarm is activated to sound an alarm, wherein the third preset water level value is greater than the second preset water level value.

[0066] Specifically, the third preset water level value is also stored in the controller. The controller can communicate with the third water level sensor in real time to obtain the detected third water level value and compare it with the internally stored third preset water level value. Preferably, the third preset water level value is the water level at the top of the float device 3.

[0067] In a preferred embodiment of the present invention, after the water turbine 22 operates at high speed, if the second water level value drops below the second preset water level value, the water turbine 22 switches to low-speed operation.

[0068] Specifically, when the power of the portable air conditioner is reduced, the second water level may drop below the second preset water level. In this case, it is only necessary to switch the water impeller 22 to low speed operation.

[0069] The drainage control method of this invention compares a first water level value with a first preset water level value, and a second water level value with a second preset water level value, to determine the operating speed of the water-pumping wheel 22, thereby controlling the operating speed of the water-pumping wheel 22 more precisely and saving electricity. A comparison of a third water level value with a third preset water level value determines whether an alarm is needed to empty the water in the storage pan 1. Because the drainage control device of this invention ensures that the water level around the float device 3 does not fluctuate due to the operation of the water-pumping wheel 22, the alarm is accurate, preventing frequent alarms caused by water level errors and reducing the frequency of water emptying.
