Description

Technical Field

[0001] The present invention relates to the technical field of pet care, and in particular to a cleaning method of a pet cleaning machine with a detachable water tank. Background Art

[0002] A pet washing machine is a cleaning device designed specifically for pets, automatically completing bathing and drying processes, saving time and effort. A typical pet washing machine uses a water pump connected to a tap water line to supply clean water to the washing chamber. A drain pipe is located at the bottom of the washing chamber to remove wastewater.

[0003] Chinese invention patent application number 202410955195.9 discloses a fully automatic pet washing machine, a control method for the fully automatic pet washing machine, and a control system. The method includes the following steps:

[0004] Step 1: Adjust parameters based on pet type, pet physique, hair type, etc.

[0005] Step 2: Open the door, let the pet enter the internal cleaning chamber, and then close the door;

[0006] Step 3: After starting the machine, the door begins to lock. Once locked, the door cannot be opened. Then, water begins to flow in from the faucet into the machine, passing through the heating system to become warm water. It then flows into the top nozzle and side water mist nozzles to moisten the pet's hair. The shower gel is controlled to be released from the storage box, through the pipe, through the Venturi tube, and mixed with the cleaning water. It is then sent to the top nozzle and side water mist nozzles to spray the pet.

[0007] Step 4: Turn off the switch of the shower gel storage box, close the nozzle and side nozzles, and let the shower gel foam soak on the pet for a while. At the same time, turn on the switch of the water inlet from the bottom. Water enters the machine from the faucet, passes through the heating system, becomes warm water, and enters the bottom water inlet. The water is filled to the predetermined water level (the water level should be close to the pet's abdomen, not higher than the pet's mouth and nose to prevent the pet from choking). Turn on the rotating mechanism at the bottom of the safety partition to drive the water flow to flush the pet. Then, turn on the top nozzle and side nozzles at the same time to flush the foam and clean the pet.

[0008] Step 5: After cleaning, drain the water. After the water is drained, open the top nozzle and the side water mist nozzle to rinse the pet;

[0009] Step 6: After cleaning, turn on the drying system and dry the pet hair by blowing hot air;

[0010] Step 7: After cleaning, open the bath door and let the pet out;

[0011] Step 8: Close the door and turn on the UV light to disinfect and remove odors.

[0012] However, this design, which relies on a fixed water source and drainage pipes, has significant limitations in practical deployment. It's unsuitable for homes lacking fixed water inlets and drains, such as living rooms or balconies. Connecting water pipes and draining wastewater becomes extremely difficult or even impractical. While a small number of pet washers with removable clean water and wastewater tanks are available on the market, these cleaning processes often rely solely on traditional tankless designs, neglecting to monitor the tank's operating status in real time.

[0013] The lack of clean water tank monitoring prevents the device from detecting water shortages, resulting in an inability to automatically terminate cleaning or alert the user when water is low. Similarly, the lack of wastewater tank monitoring means the device can neither detect whether the wastewater tank is in place nor determine whether it is full. This results in a lack of notifications when the wastewater tank is not installed, and an inability to automatically terminate cleaning or issue an alarm when it is full. This lack of monitoring capabilities not only limits the device's intelligence level but also directly impacts the user experience and convenience, requiring urgent improvement. Summary of the Invention

[0014] The technical problem to be solved by the present invention is to propose a cleaning method for a pet washing machine with a detachable water tank that can monitor the status of a clean water tank and a sewage tank in response to the above technical status.

[0015] The technical solution adopted by the present invention to solve the above technical problems is: a cleaning method of a pet cleaning machine with a detachable water tank, characterized by comprising the steps of:

[0016] Run the water tank monitoring program and continuously monitor whether there is water in the clean water tank, whether the sewage tank is loaded, and whether the sewage tank is not full during the entire cleaning process. If all monitoring feedbacks are yes, continue with the subsequent steps. If any monitoring feedback is no, do not start or interrupt the cleaning program.

[0017] In order to be able to directly and accurately monitor whether there is water in the clean water tank, as a preferred method, the water outlet of the clean water tank is downwardly arranged in the clean water cavity of the pet washing machine housing, and the water in the clean water tank can flow out into the clean water cavity. Two monitoring electrodes are arranged at the bottom of the clean water cavity to monitor whether there is water in the clean water tank in real time:

[0018] When the two monitoring electrodes are connected by the water at the bottom of the water purification chamber to form a path, the monitoring result of whether there is water in the water purification tank is fed back to the water tank monitoring program as yes;

[0019] When the two monitoring electrodes cannot conduct due to lack of water at the bottom of the clean water chamber and form a circuit break, the monitoring result of whether there is water in the clean water tank is fed back to the water tank monitoring program as no.

[0020] In order to ensure that there is no leakage when the clean water tank is removed and that the water supply can be automatically connected when it is installed, it is preferred that when the clean water tank is replenished with water and then installed into the clean water chamber, the piston in the clean water tank cover is pushed by the top column at the bottom of the clean water chamber to release the sealing state of the piston's axial channel, allowing clean water to flow into the clean water chamber; when the clean water tank is taken out, the piston is reset under the action of the compression spring and the axial channel is sealed.

[0021] In order to directly and accurately monitor whether the sewage tank is loaded into the pet washing machine, it is preferred that a magnetic induction device is arranged near the sewage chamber of the pet washing machine, and a float with a magnet is arranged in the float chamber above the sewage tank. The magnetic induction device corresponds to the position of the magnet when the sewage tank is placed in the sewage chamber. The magnetic induction device senses the presence of the magnet to monitor in real time whether the sewage tank is loaded into the sewage chamber.

[0022] When the magnetic induction device detects the magnet, it feeds back to the water tank monitoring program whether the sewage tank is loaded with a monitoring result of yes;

[0023] When the magnetic induction device cannot detect the magnet, the monitoring result of whether the sewage tank is loaded is fed back to the water tank monitoring program as no.

[0024] In order to monitor whether the sewage tank is not full by relying on the magnet and magnetic induction device without introducing additional structures, it is preferred that a water inlet is opened in the float chamber so that sewage can enter the float chamber. After receiving a positive monitoring result of whether the sewage tank is filled, the magnetic induction device senses whether the magnet exists to monitor whether the sewage tank is not full of sewage in real time:

[0025] When the magnetic induction device detects the magnet, the sewage has not yet entered the float chamber to cause the float and the magnet it carries to float up, or the sewage has entered the float chamber but the floating height of the magnet has not yet caused the magnet to leave the sensing range of the magnetic induction device. At this time, the monitoring result of whether the sewage tank is full of sewage is fed back to the water tank monitoring program as no;

[0026] When the magnetic induction device cannot detect the magnet, sewage enters the float chamber and the floating height of the magnet is sufficient to make the magnet out of the sensing range of the magnetic induction device. At this time, the monitoring result of whether the sewage tank is full of sewage is fed back to the water tank monitoring program as yes.

[0027] To enhance human-computer interaction, further, when the water tank monitoring program receives a negative test result, it issues a reminder to the user corresponding to the situation:

[0028] When the monitoring result of whether there is water in the clean water tank is no, the user is reminded that the clean water tank is short of water;

[0029] When the monitoring result of whether the sewage tank is loaded is no, the user is reminded that the sewage tank is not loaded;

[0030] When the monitoring result of whether the sewage tank is not full is no, the user is reminded that the sewage tank is full.

[0031] After all three of the above monitoring items are passed, the pet cleaning machine runs the cleaning program. Specifically, the cleaning program includes the following steps:

[0032] The water in the clean water chamber will be pumped away by the first pump and enter the top nozzle to wet the pet hair. At the same time, the second pump is turned on and the sewage is continuously pumped into the sewage tank.

[0033] The sterilizing and insecticide liquid is pumped in through the pump, mixed with the water in the clean water tank, and then sent to the top nozzle to spray on the pet for a period of time, and then the spraying is stopped to allow the sterilizing and insecticide liquid foam to soak on the pet for a period of time;

[0034] Open the top nozzle again, flush the bactericidal and insecticide foam and wash the pet for a while;

[0035] Cleaning completed.

[0036] Furthermore, after completing the cleaning process, a drying process is run, comprising the steps of:

[0037] Turn on the fan, heater, and negative ion generator to dry the pet in the cleaning chamber according to the set time or intelligent drying time;

[0038] The door will open automatically after drying is completed, and a voice prompt will be given to remind the user that drying is complete and to clean the sewage tank.

[0039] In order to prevent the pet from being suffocated in the pet washing machine when the door cannot be opened due to an accident, preferably, after the drying is completed, if the automatic door opening fails, the fresh air care program is automatically run to turn on the fresh air system of the pet washing machine.

[0040] Preferably, before starting the cleaning procedure, the method further comprises the following steps:

[0041] Adjust the parameters of the cleaning and drying programs according to the pet type, pet physique, and hair, including determining the cleaning mode as atomization or spraying water flow, washing time, water temperature, drying time, and drying temperature.

[0042] Compared with the existing technology, the advantage of the present invention is that it solves the problem of missing key monitoring in existing pet washing machines with detachable water tanks. By forcibly and continuously monitoring the water level of the clean water tank, the installation status of the sewage tank, and the fullness of the sewage tank throughout the cleaning process, and setting "all monitoring passed" as a necessary condition for the program to run, the inherent safety and reliable operation of the equipment are achieved. The present invention can effectively avoid the risk of dry burning of the water pump due to lack of water, environmental pollution and equipment short circuit caused by the sewage tank not being installed or overflowing, and can significantly improve the user experience. Users do not need to worry about or manually check the status of the water tank all the time. The equipment can independently decide to pause or terminate the cleaning program, ensuring the true convenience and feasibility of use in environments without fixed water sources such as ordinary living rooms and balconies.

[0049] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0050] like Figures 1 to 6 FIG. 1 shows a preferred embodiment of a cleaning method for a pet cleaning machine with a detachable water tank according to the present invention.

[0051] The core workflow of this embodiment is as follows Figure 1 As shown, the steps include:

[0052] Run the water tank monitoring program and continuously monitor whether there is water in the clean water tank 4, whether the sewage tank 5 is loaded, and whether the sewage tank 5 is not full during the whole cleaning process. If all monitoring feedbacks are yes, then continue with the subsequent steps. If any monitoring feedback is no, it is determined that there is an abnormality and the cleaning program will not be started or interrupted;

[0053] Adjust the parameters of the washing and drying programs according to the pet type, physique, and hair, including determining the washing mode as atomization or spraying water flow, washing time, water temperature, drying time, and drying temperature;

[0054] When the cleaning program is running, the water in the clean water chamber 2 will be pumped away by the first water pump and enter the top nozzle to moisten the pet's hair. At the same time, the second water pump is turned on to continuously pump the sewage into the sewage tank 5. The sterilizing and insecticide liquid is added by the injection pump, mixed with the water in the clean water tank, and then sent to the top nozzle 6 to spray the pet for a period of time. Then, the spraying is stopped to allow the foam of the sterilizing and insecticide liquid to soak on the pet for a period of time. The top nozzle 6 is opened again to flush the foam of the sterilizing and insecticide liquid and clean the pet for a period of time until the cleaning is completed.

[0055] Run the drying program, turn on the fan, heater, and negative ion generator to dry the pet in the cleaning chamber according to the set time or intelligent drying time; the door will automatically open after drying is completed, and the voice will remind the user that drying is completed, and the voice will prompt to clean the sewage tank 5.

[0056] Regarding monitoring whether there is water in the clean water tank 4, specifically, this embodiment sets the water outlet of the clean water tank 4 downward in the clean water chamber 2 of the pet washing machine casing 1, and the water in the clean water tank 4 can flow out into the clean water chamber 2. By setting two monitoring electrodes 24 at the bottom of the clean water chamber 2, it is monitored in real time whether there is water in the clean water tank 4: when the two monitoring electrodes 24 are conducted by the water at the bottom of the clean water chamber 2 to form a passage, the monitoring result of whether there is water in the clean water tank 4 is fed back to the water tank monitoring program as yes; when the two monitoring electrodes 24 cannot be conducted due to lack of water at the bottom of the clean water chamber 2 and form a circuit break, the monitoring result of whether there is water in the clean water tank 4 is fed back to the water tank monitoring program as no.

[0057] Regarding monitoring whether the sewage tank 5 is loaded, specifically, in this embodiment, a magnetic induction device 35 is arranged near the sewage chamber 3 of the pet washing machine, and a float with a magnet 512 is arranged in the float chamber 51 on the upper part of the sewage tank 5. The magnetic induction device 35 corresponds to the position of the magnet 512 when the sewage tank 5 is placed in the sewage chamber 3. The magnetic induction device 35 senses whether the magnet 512 exists to monitor in real time whether the sewage tank 5 is loaded into the sewage chamber 3: when the magnetic induction device 35 detects the magnet 512, the monitoring result of whether the sewage tank 5 is loaded is fed back to the water tank monitoring program as yes; when the magnetic induction device 35 cannot detect the magnet 512, the monitoring result of whether the sewage tank 5 is loaded is fed back to the water tank monitoring program as no.

[0058] To monitor whether the sewage tank 5 is full, specifically, in this embodiment, a water inlet is opened in the float chamber 51 so that sewage can enter the float chamber 51, and a magnet 512 is fixedly connected to the float 511. After receiving a positive monitoring result of whether the sewage tank 5 is filled, the magnetic induction device 35 senses whether the magnet 512 exists to monitor in real time whether the sewage tank 5 is not full of sewage: when the magnetic induction device 35 detects the magnet 512, the sewage has not yet entered the float chamber 51, causing the float 511 and the magnet 512 it carries to be on the float chamber 51. Floating, or sewage has entered the float chamber 51 but the floating height of the magnet 512 has not yet made the magnet 512 out of the sensing range of the magnetic induction device 35, at this time, the monitoring result of whether the sewage tank 5 is full of sewage is fed back to the water tank monitoring program as no; when the magnetic induction device 35 cannot detect the magnet 512, sewage has entered the float chamber 51 and the floating height of the magnet 512 is sufficient to make the magnet 512 out of the sensing range of the magnetic induction device 35, at this time, the monitoring result of whether the sewage tank 5 is full of sewage is fed back to the water tank monitoring program as yes.

[0059] When the water tank monitoring program receives a negative test result, it will send a reminder corresponding to the situation to the user: when the monitoring result of whether there is water in the clean water tank is negative, the user is reminded that the clean water tank is short of water; when the monitoring result of whether the sewage tank 5 is loaded is negative, the user is reminded that the sewage tank 5 is not loaded; when the monitoring result of whether the sewage tank 5 is not full is negative, the user is reminded that the sewage tank 5 is full.

[0060] It should be noted here that although the magnetic induction device 35 is unable to sense the magnet 512, being able to sense the magnet 512 initially but being unable to sense it subsequently and being unable to sense the magnet 512 initially are two different states. When the state is the former, the user is reminded that the sewage tank 5 is full, and when the state is the latter, the user is reminded that the sewage tank 5 is not loaded.

[0061] In order to ensure that there is no leakage when the clean water tank is removed and that the water supply can be automatically connected when it is installed, when the clean water tank 4 is replenished with water and then installed into the clean water chamber 2, the piston 412 in the clean water tank cover 41 is pushed by the top column 25 at the bottom of the clean water chamber 2, thereby releasing the sealing state of the axial channel 411 of the piston 412 and allowing the clean water to flow into the clean water chamber 2; when the clean water tank 4 is taken out, the piston 412 is reset under the action of the compression spring 416 and seals the axial channel 411.

[0062] In addition, in order to prevent the pet from being suffocated in the pet washing machine when the door 11 cannot be opened due to an accident, after the drying is completed, if the automatic door opening fails, the fresh air care program will be automatically run to turn on the fresh air system of the pet washing machine.

[0063] This embodiment also proposes a specific structure of a pet cleaning machine that matches the above cleaning method, including a housing 1, such as Figure 2 and Figure 3As shown, the housing 1 is provided with a clean water chamber 2, a sewage chamber 3, and a cleaning chamber 7. The clean water chamber 2 removably accommodates a clean water tank 4, the sewage chamber 3 removably accommodates a sewage tank 5, and the cleaning chamber 7 is used to accommodate and clean pets. A clean water chamber cover is provided above the clean water chamber 2, which allows the clean water tank 4 to be removed and replaced. The sewage chamber 3 also has a sewage chamber cover, which allows the sewage tank 5 to be removed and replaced.

[0064] The bottom of the clean water chamber 2 is connected to the nozzle 6 at the top of the cleaning chamber 7 via a clean water channel 22. The drain outlet at the bottom of the cleaning chamber 7 is connected to the top of the sewage chamber 3 via a sewage channel. A first pump is installed in the clean water channel 22 to pump clean water from the clean water chamber 2 to the cleaning chamber 7. The sewage channel is equipped with a filter to filter impurities from the sewage and a second pump to pump sewage from the cleaning chamber 7 to the sewage chamber 3. The clean water tank 4 can be filled not only with cleaning water but also with fungicides and disinfectants to achieve both cleaning and sterilization effects.

[0065] like Figure 4 and Figure 5 As shown, a clean water outlet is provided at the bottom of the clean water tank 4, and the clean water outlet is in fluid communication with the clean water chamber 2. A clean water monitoring device is provided in the housing 1, and the clean water monitoring device includes two monitoring electrodes 24, which are arranged at intervals at the bottom of the clean water chamber 2. When clean water exists in the clean water chamber 2, the two monitoring electrodes 24 are connected by the clean water. The clean water monitoring device is configured to send a signal indicating a lack of water in the clean water tank 4 when the two monitoring electrodes 24 are not connected. By monitoring the on-off status of the two monitoring electrodes 24, real-time monitoring of the water shortage status of the clean water tank 4 can be achieved. At the same time, since the clean water monitoring device is independently provided in the clean water chamber 2 and does not rely on the structure of the clean water tank 4, the clean water tank 4 can be easily disassembled to take out water without the need to simultaneously disassemble or adjust the monitoring device each time it is disassembled.

[0066] The clean water tank 4 includes a clean water tank cover 41, which can be threadedly connected to the clean water outlet. The user takes out the clean water tank 4 from the clean water chamber 2, fills it with clean water, screws on the clean water tank cover 41, and then puts it back upside down into the clean water chamber 2. In order to prevent the clean water outlet from discharging water during the return process and to ensure that water flows normally after the clean water tank 4 is put into place, the present embodiment provides an axial channel 411 in the clean water tank cover 41, and a piston 412 that can slide axially is provided in the axial channel 411. A sealing ring is provided on the outer periphery of the piston 412. When the piston 412 slides until the sealing ring is in close contact with the axial channel 411, the sealing ring can seal the axial channel 411. The inner wall of the axial channel 411 of the clean water tank cover 41 protrudes inward to form a first annular flange, and the outer periphery of the piston 412 protrudes outward to form a second annular flange. A compression spring 416 is provided around the outer periphery of the piston 412. One end of the compression spring 416 abuts against the first annular flange, and the other end abuts against the second annular flange. Under the action of the compression spring 416, the piston 412 always tends to slide away from the clean water tank 4, so that the sealing ring maintains the state of sealing the axial channel 411. Figure 3 shown.

[0067] A top post 25 is provided at the bottom of the clean water chamber 2. The position of the top post 25 corresponds to the position of the piston 412 when the clean water tank 4 is accommodated in the clean water chamber 2. When the clean water tank 4 is placed in the clean water chamber 2, the top post 25 pushes the piston 412 upward, so that the sealing ring releases the seal of the axial channel 411, and the interior of the clean water tank 4 is in fluid communication with the clean water chamber 2 through the axial channel 411. Figure 2 As shown. When the water exceeds the clean water outlet of the clean water tank 4, under the action of atmospheric pressure, the inside and outside of the clean water tank 4 are balanced, and the clean water outlet no longer discharges water. The water stored in the clean water chamber 2 connects the two monitoring electrodes 24, and the cleaning program begins. The first water pump will extract the clean water at the bottom of the clean water chamber 2. As the water level drops, the clean water outlet of the clean water tank 4 is exposed, the atmospheric pressure fails, and the water inside the clean water tank 4 will continue to flow out. Until the clean water in the clean water tank 4 flows out and the two monitoring electrodes 24 can no longer be connected by the water stored at the bottom of the clean water chamber 2, the clean water monitoring device sends a signal to the control center that the clean water tank 4 is short of water, and the cleaning program is interrupted.

[0068] refer to Figure 6The upper portion of the sewage tank 5 is provided with a float chamber 51, with a water inlet at its bottom. A float 511 is housed within the float chamber 51, which rises and falls with the water level. A magnet 512 is fixedly mounted within the float 511, rising and falling with the float 511. The float chamber 51 is approximately the same size as the float 511, preventing the float 511 from rotating during the rise and fall process. Small holes are provided in the sidewalls of the float chamber 51 to facilitate the flow of air and sewage. A sewage tank monitoring device is housed within the housing 1. The device includes a magnetic sensor 35. When the water level in the sewage tank 5 is below a preset level, the magnet 512 is within the sensing range of the magnetic sensor 35. When the water level in the sewage tank 5 is above the preset level, the magnet 512 is out of the sensing range of the magnetic sensor 35. The preset water level can be set to the full water level or near the full water level. The sewage tank monitoring device is configured to: send a signal indicating that the sewage tank 5 is not loaded into the sewage chamber 3 when the magnetic induction device 35 does not detect the magnet 512; and send a signal indicating that the sewage tank 5 is full when the magnetic induction device 35 initially detects the magnet 512 but is unable to detect the magnet 512 thereafter.

[0069] When the pet cleaning machine is turned on and used, if the sewage tank monitoring device does not detect the magnet 512, it will remind you that the sewage tank 5 is not installed and the cleaning program will not be executed; if the sewage tank monitoring device detects the magnet 512, the cleaning program runs normally, and then when the sewage tank 5 is full of water, the magnet 512 leaves the sensing area, the cleaning program stops, and the user takes out the sewage tank 5 to pour out the sewage. The initial failure to detect the magnet 512 and the initial ability to detect the magnet 512 but not being able to detect it later are two different state descriptions. The sewage in the sewage tank 5 all comes from the clean water tank 4, so the volume of the sewage tank 5 can be designed to be slightly larger than the volume of the clean water tank 4 to ensure that only the clean water tank 4 and the sewage tank 5 need to be replaced once each time cleaning.

[0070] An overflow channel is opened at the bottom of the sewage chamber 3 to prevent sewage from overflowing from the casing 1 when the program or magnetic induction fails. The sewage overflowing from the sewage tank 5 enters the sewage chamber 3 and gathers at the bottom of the sewage chamber 3. The overflowed sewage is diverted to the sewage channel through the overflow channel.

[0071] In this embodiment, the sewage tank 5 and the clean water tank 4 are combined into an integrated water tank on the left and right sides, and the clean water chamber 2 and the sewage chamber 3 are combined into an integrated cavity. The clean water chamber cover and the sewage chamber cover are also changed to a single cavity cover 20, so there is no problem of missing a water tank. In addition, the sewage tank 5 and the clean water tank 4 can also be combined into an integrated water tank on the top and the clean water tank 4 on the bottom.
