Description

Technical Field

[0001] This invention relates to the field of dishwasher technology, and more specifically to a method, apparatus, control device for removing residual water from a dishwasher, dishwasher, electronic equipment, and computer-readable storage medium. Background Technology

[0002] After washing and drying, the dishwasher needs to be drained of any remaining water from the washing chamber.

[0003] In existing technologies, residual water in the washing chamber is removed by using a residual water pump. Typically, the inlet of the residual water pump is connected to the drain outlet of the washing chamber via a water pipe, so that the residual water in the washing chamber can be removed after the residual water pump is turned on, allowing the washing chamber to remain dry.

[0004] During the washing process, dishwashing water in the washing chamber can seep into the water pipes. If the seal on the shaft of the residual water pump corrodes, dishwashing water can seep into the shaft, causing the motor of the residual water pump to rust. Over time, the motor may fail to rotate properly, leading to abnormal operation of the dishwasher. Summary of the Invention

[0052] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0055] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] During the development of dishwashers, long-term experimental operation is required. In one dishwasher currently under development, a problem with the residual water pump was discovered during long-term testing. When the dishwasher reaches the residual water removal stage, it immediately resets and re-enters a memory state, continuously looping this action. Disassembly and inspection of the residual water pump revealed that the motor shaft was rusted and unable to rotate. The dishwasher's mainboard switching power supply is designed to handle a maximum load of 10W, but actually handles 8.3W. The residual water gear pump normally operates at 12V / 0.2A, actually only drawing 2.4W. However, when the gears of the residual water pump stall, the stall current reaches 1A, and the power consumption reaches 12W, exceeding the maximum load of the switching power supply. The power supply's overload protection repeatedly shuts down and restarts, triggering hardware protection when the residual water pump is powered on. This phenomenon severely affects normal washing.

[0057] The drain pump's shaft has a sealing ring. When the dishwasher is washing, if wash water seeps into the drain pump through this ring, the detergent dissolves in the water, and the high temperature corrodes the ring. Over time, the seal becomes compromised, and the wash water causes the shaft to rust and become unable to rotate. In this situation, the dishwasher will not function properly after starting the wash cycle. Closing the control valve prevents wash water from entering the drain pump, thus preventing corrosion of the sealing ring.

[0058] Example 1

[0059] like Figure 1 The diagram shows a flowchart of a method for removing residual water from a dishwasher. This method includes:

[0060] Step S101: In the washing state of the dishwasher, close the control valve 4 that controls the residual water to enter the residual water pump 3;

[0061] Step S103: In the non-washing state of the dishwasher, open the control valve 4.

[0062] When the dishwasher is in the washing state, control valve 4 is closed, blocking the passage between drain outlet 1 and residual water inlet 31 of residual water pump 3. This prevents washing water from entering residual water pump 3, thus preventing corrosion of the motor shaft of residual water pump 3 due to the ingress of washing water and ensuring its normal operation. Control valve 4 is closed only when the dishwasher is washing dishes; it remains open during other stages. This prevents washing water from entering residual water pump 3, extending its service life and ensuring timely removal of residual water from the washing chamber after washing. When residual water pump 3 is operating normally, it guarantees the normal washing and drying states of the dishwasher.

[0063] Furthermore, such as Figure 2 As shown, when the dishwasher is not in the washing state, opening control valve 4 specifically includes:

[0064] Step S201: After the dishwasher finishes draining and enters the drying state, open control valve 4;

[0065] Step S203: Control the residual water pump 3 to work for the first time and then shut it down.

[0066] In the dishwasher described above, during the final drying stage of the washing cycle, drain pump 2 finishes draining water, and the solenoid valve opens. At this point, the remaining water in the washing chamber is relatively clean and at a low temperature. After opening the solenoid valve, drain pump 3 runs for a short time and then shuts off, ensuring that there is no remaining water in the washing chamber and guaranteeing its dryness. This short time can be 2 minutes. The value of the short time can be determined experimentally.

[0067] Furthermore, such as Figure 3 As shown, when the dishwasher is not in the washing state, opening control valve 4 specifically includes:

[0068] Step S205: After the dishwasher finishes drying, control the residual water pump 3 to work again for a second time and then turn it off.

[0069] When the residual water pump 3 is turned off, the washing chamber is still in the drying state, and some residual water may remain, or water vapor may be discharged during the drying process. When some residual water or water vapor enters the solenoid valve, and the residual water pump 3 is controlled to run for a second time after the dishwasher finishes drying, it is then turned off. This not only ensures that there is no residual water in the washing chamber of the dishwasher, but also that there is no residual water in the residual water pump 3, achieving the drying effect. The second time can be 2 minutes.

[0070] Furthermore, such as Figure 4 As shown, the methods for removing residual water from a dishwasher also include:

[0071] Step S301: Turn on the residual water pump 3 at the preset time;

[0072] Step S303: After the residual water pump 3 has been running for three hours, it will be shut down.

[0073] Considering that frequent rotation of the motor shaft of the residual water pump 3 can provide some lubrication, the dishwasher needs to select a fixed time period when it is not needed to run dishes and run the residual water pump 3 regularly. For example, 6:00 AM every day can be used as the preset time. When the time reaches 6:00 AM every day, the residual water pump 3 should be controlled to run for 1 minute and then turned off. This will ensure that the motor of the residual water pump 3 can rotate normally and ensure the stable lubrication performance of the motor shaft, thereby further ensuring that the residual water pump 3 maintains a normal working state.

[0074] Furthermore, such as Figure 5 As shown, the methods for removing residual water from a dishwasher also include:

[0075] Step S401: Obtain the real-time power of the residual water pump 3;

[0076] Step S403: When the real-time power is greater than the preset power, an alarm signal is issued.

[0077] The dishwasher's mainboard switching power supply is designed to handle a maximum load of 10W, but actually handles 8.3W, leaving a 1.7W margin. To prevent the mainboard from resetting due to overcurrent protection and to avoid fluctuations in other loads, 1W is reserved for other loads. The extra 0.7W is allocated to the residual water pump 3. The residual water pump 3 operates normally at 12V / 0.2A with a power consumption of only 2.4W. When the power consumption of the residual water pump 3 is ≥2.4 + 0.7W, a fault warning can be issued. Therefore, the preset power can include 5W. During the operation of the residual water pump 3, its power consumption is monitored. When the power consumption reaches 5W, an alarm signal can be issued to indicate a problem with the residual water pump 3. The alarm signal can include audible signals, visual signals, or a combination of audible and visual signals, as well as interpretable alarm information such as text signals, thus improving reliability.

[0078] More specifically, such as Figure 6As shown, the method for removing residual water from a dishwasher may include the following steps:

[0079] Step S501: The solenoid valve controls the residual water to enter the residual water pump 3;

[0080] Step S503: When it is determined that the dishwasher is in the non-washing stage, according to daily dishwashing habits, such as running the residual water pump 3 for 1 minute at 6 am every day, the residual water pump 3 shaft can be lubricated.

[0081] Step S505: When it is determined that the dishwasher is in the washing stage, when the washing mode is started, the solenoid valve closes to prevent residual water from entering the residual water pump 3.

[0082] Step S507: After the final drying stage is reached, the drainage pump 2 finishes draining, the solenoid valve opens and the residual water pump 3 runs to remove residual water for 2 minutes;

[0083] Step S509: After the air drying is completed, run the residual water pump 3 again for 2 minutes to remove residual water, and the washing is complete;

[0084] Step S511: When the residual water pump 3 is running, if it is determined that the residual water power is greater than 5W, then the residual water pump 3 is faulty.

[0085] In the above steps, based on the analysis of the test problems, corrosion of the sealing ring on the shaft of the residual water pump 3 causes dishwashing water to seep into the shaft, leading to rust on the motor of the residual water pump 3. Over time, the motor will fail to rotate properly, causing malfunctions in the dishwasher. Therefore, the sealing problem of the residual water pump 3's sealing ring needs to be addressed. This requires not only replacing the materials, for example, using a more airtight rubber ring to isolate the washing water from the shaft, but also monitoring the power of the residual water pump 3 to prevent corrosion of the sealing ring and lubrication issues on the shaft. Optimizing the existing washing logic and structure, adding fault indicators, and improving reliability are also necessary. The solenoid valve only closes during the dishwasher's dishwashing process and opens during other stages to ensure the residual water pump 3 remains dry.

[0086] Example 2

[0087] like Figure 7 and Figure 8 As shown, a dishwasher drain removal device is used in a dishwasher. The dishwasher has a drain outlet 1. The drain removal device includes a drain pump 3, a control valve 4, and a control system 8. The drain pump 3 has a residual water inlet 31, and the control valve 4 has a valve inlet and a valve outlet. The valve inlet is connected to the drain outlet 1, and the valve outlet is connected to the residual water inlet 31. The control system 8 is communicatively connected to the drain pump 3 and the control valve 4, respectively. The control system 8 is adapted to acquire washing status information and non-washing status information, and controls the opening or closing of the drain pump 3 and / or the control valve 4 according to the washing status information or the non-washing status information.

[0088] The dishwasher described above includes a washing chamber where dishes are washed. A drain outlet 1 is located at the bottom of the washing chamber. A control valve 4 is connected to the water supply line between the drain outlet 1 and the residual water inlet 31 of the residual water pump 3. The control valve 4 can be a solenoid valve. The residual water pump 3 may include a gear pump and also has a residual water outlet 32, which discharges residual water through a residual water pipe 5. When the control system 8 receives washing status information, it closes the control valve 4, preventing washing water from entering the residual water pump 3. Therefore, the motor shaft of the residual water pump 3 will not be corroded by the entry of washing water, ensuring the normal operation of the residual water pump 3. When the control system 8 receives non-washing status information of the dishwasher, it opens the control valve 4, ensuring that there is no residual water in the residual water pump 3. During the drying stage, hot air from the washing chamber enters the residual water pump 3 through the control valve 4, thereby drying the residual water pump 3.

[0089] Furthermore, continue to combine Figure 8 As shown, the dishwasher's residual water removal device also includes an alarm device 9, which is communicatively connected to the control system 8. The control system 8 is adapted to obtain the real-time power of the residual water pump 3, and when the real-time power is greater than the preset power, the control system 8 controls the alarm device 9 to issue an alarm signal.

[0090] The aforementioned control system 8 can obtain the real-time power of the residual water pump 3. By detecting the power of the residual water pump 3, when the power reaches 5W, the control system 8 sends a signal to control the alarm device 9 to issue an alarm signal to remind that there is an operational problem with the residual water pump 3.

[0091] Example 3

[0092] A dishwasher includes: a dishwasher water removal device; and / or a dishwasher water removal method capable of performing any one of the above.

[0093] The dishwasher described above can prevent external factors during the washing phase from affecting the sealing performance of the seal ring of the residual water pump 3 shaft and avoid the problem of the shaft rusting and becoming unable to rotate by closing the control valve 4 during the washing phase and closing the control valve 4 during the non-washing phase.

[0094] Furthermore, such as Figure 7 As shown, the dishwasher also includes a drain pump 2 and a drain pipe 6. The drain pump 2 has a pump inlet and a pump outlet. The pump inlet is connected to the drain outlet 1, and the drain pipe 6 is connected to the pump outlet.

[0095] The dishwasher described above can use the drain pump 2 to discharge the washing water in the washing chamber through the drain pipe 6.

[0096] Example 4

[0097] like Figure 9As shown, a dishwasher residual water control device 10 includes: a judgment module 101 and a control module 102. The judgment module 101 is adapted to determine whether the dishwasher is in the washing state. The control module 102 is communicatively connected to the judgment module 101. When the judgment module determines that the dishwasher is in the washing state, the control module 102 closes the control valve 4 that controls the residual water to enter the residual water pump; or when the judgment module 101 determines that the dishwasher is in the non-washing state, the control module 102 opens the control valve 4.

[0098] Example 5

[0099] like Figure 10 As shown, an electronic device 7 includes at least a memory 71 and a processor 72. The memory 71 stores a computer program, and the processor 72 implements the dishwasher water removal method described in any one of the methods when executing the computer program in the memory 71.

[0100] The program steps of the aforementioned electronic computer are as follows: In the washing state of the dishwasher, close the control valve that controls the residual water to enter the dewatering pump; in the non-washing state of the dishwasher, open the control valve.

[0101] Example 6

[0102] A computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, implements any one of the methods for removing residual water from a dishwasher.

[0103] The readable storage medium is a computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, it implements the above-mentioned method for removing residual water from a dishwasher.

[0104] Those skilled in the art will understand that implementing all or part of the processes in the above embodiments can be accomplished by a computer program instructing related hardware. The program can be stored in a computer-readable storage medium, and when executed, it can include the processes of the embodiments of the above methods. The storage medium can be a magnetic disk, optical disk, read-only memory (ROM), random access memory (RAM), flash memory, hard disk drive (HDD), or solid-state drive (SSD), etc.; the storage medium may also include combinations of the above types of memory.

[0105] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
