[0023] Optionally, the water temperature control method of the clothes washing device further includes: obtaining the water inlet time of the water storage component; when the water inlet time reaches the preset time and the water temperature in the water storage component has not reached the target water temperature, controlling the water basin water outlet device to open when the water temperature in the water storage component reaches the third preset temperature.

[0024] Optionally, the third preset water temperature satisfies: T1 - N3 < the third preset water temperature < T1 + N3, where T1 represents the target water temperature and N3 represents the third temperature difference value.

[0025] Therefore, another technical problem to be solved by the present invention is to overcome the defect that the washing device that integrates the washing basin and the washing machine in the prior art cannot meet the washing basin's requirements for different inlet water temperatures, thereby providing a computer-readable storage medium that can meet the washing basin's requirements for different inlet water temperatures.

[0049] 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.

[0050] In existing technologies, adding a separate water heating module to the washing tub of a washing machine would be too costly, take up space, and make it difficult to guarantee safety.

[0051] Example 1

[0052] like Figure 1 The diagram shows a laundry washing device according to one embodiment. The laundry washing device includes: a washing tub 1, a water pumping assembly 3, a water basin 7, and a control assembly. The washing tub 1 is equipped with a heating device 11 to heat the water entering the washing tub 1. The water pumping assembly 3 is equipped with a water pump 31. The water pumping assembly 3 is connected to the washing tub 1 and the water basin 7. The control assembly is communicatively connected to the water pump 31 and the heating device 11 respectively, so as to control the heating device 11 to heat according to the target water temperature and control the water pump 31 to input the water in the washing tub 1 into the water basin 7.

[0053] The aforementioned washing drum 1 is the inner drum, and the washing device also includes an outer drum. A heating device 11 is disposed between the washing drum 1 and the outer drum; for example, the heating device 11 can be disposed directly below the washing drum 1. The heating device 11 can be an electric heater, which includes a heating element and a temperature sensor. For example, the temperature sensor can provide feedback on the water temperature to control the water temperature inside the washing drum 1, thus achieving the heating function.

[0054] The control components include a control board, which supplies power to the heating device 11 to heat the water in the washing tub 1. The software controls the heating device 11 via the main control board.

[0055] The water pumping assembly 3 includes a water pump 31 and a hose. One end of the hose is connected to the washing tub 1, and the water pump 31 is mounted on the hose to pump water from the washing tub 1 into the basin 7 for use. A target water temperature can be set, for example, to 30 degrees Celsius. The control assembly then controls the heating device 11 to heat the washing tub 1 until the water temperature reaches 30 degrees Celsius. At this point, the control assembly activates the water pump 31 to deliver hot water to the basin 7. By utilizing the heating device 11 of the washing tub 1, the water temperature in the basin 7 can be adjusted and controlled, thus providing convenience for the user.

[0056] Furthermore, the aforementioned clothing washing device may include a washing machine, and the basin 7 may be connected to the washing machine as an integral structure. For example, when using the washing machine to wash clothes, stubborn stains on special parts such as collars and cuffs of clothes can be washed in the basin 7 before the items are put into the washing machine for washing.

[0057] Furthermore, the control components include a controller and a basin control panel. The basin control panel is equipped with a first temperature module, which is communicatively connected to the controller. The controller is also communicatively connected to the water pump 31 and the heating device 11.

[0058] The aforementioned control components can be touch-sensitive operation panels, and the controller can be the washing machine's own controller. The sink control panel can act only as a signal transmitter. When the user clicks on the sink control panel, the corresponding information is transmitted to the controller. The controller then uses its own control logic to fulfill the user's needs. Alternatively, the control components can be a combination of the controller and the sink control panel. The sink control panel can receive user settings and control other components to achieve the corresponding functions.

[0059] Users can select different water temperatures on the sink control panel. The first temperature module can include ambient temperature and adjustable temperature. The adjustable temperature can be set as needed, for example, from 20℃ to 90℃, so that the inlet water temperature of the sink 7 can be selected according to different needs to meet more requirements.

[0060] Furthermore, the control components also include a washing drum control panel, which is equipped with a second temperature module, and the second temperature module is set in a one-to-one correspondence with the first temperature module.

[0061] Specifically, the inlet water temperature that the user can select on the sink control panel can be displayed according to the existing washing temperature settings of the laundry device. For example, if the existing water temperature settings of the laundry device can be set to 20℃, 30℃, 40℃, 60℃, and 90℃, then the inlet water temperature that the user can select on the sink control panel is the same as the set water temperature of the existing water temperature settings of the laundry device. The user can select an inlet water temperature of 20℃, 30℃, 40℃, 60℃, or 90℃, which is also the target water temperature, thus simplifying the control of the target water temperature.

[0062] The adjustable temperature can be selected via a touchscreen on the control panel of the sink. Touching the touchscreen causes a change in capacitance; this change is detected to perform the desired operation.

[0063] Furthermore, the laundry washing device also includes a water storage component 5 and a first water inlet component 4. The water storage component 5 is connected to the water pumping component 3, and a temperature detection device 51 is installed inside the water storage component 5. The temperature detection device 51 is suitable for detecting the water temperature inside the water storage component 5. The first water inlet component 4 is equipped with a first water inlet valve 41 and is connected to the water storage component 5. The first water inlet valve 41 and the temperature detection device 51 are respectively communicatively connected to the control component to control the water temperature entering the water storage component 5 according to the target temperature.

[0064] The aforementioned water storage component 5 includes a water storage tank, and a temperature detection device 51 is installed inside the water storage tank. The first water inlet component 4 is also equipped with a flexible hose, one end of which is connected to an external water source 8, and the other end of which is connected to the water storage tank of the water storage component 5. A first water inlet valve 41 is installed on the flexible hose so that water can enter the water storage tank when the first water inlet valve 41 is opened. By detecting the water temperature in the water storage component 5 through the temperature detection device 51, and controlling the first water inlet valve 41, the heating device 11, and the water pump 31 according to the target water temperature, more precise control of the water temperature entering the water basin 7 can be achieved.

[0065] Furthermore, the laundry washing device also includes a water outlet device 2, which is located at the water outlet of the water storage component 5. The water outlet device 2 is communicatively connected to the control component and is adapted to supply water to the basin 7 when it is in the open state.

[0066] When the water outlet device 2 is open, the water storage component 5 and the water basin 7 are in a connected state. When the water outlet device 2 is closed, the water storage component 5 and the water basin 7 are disconnected, so that the water temperature entering the water basin 7 from the water storage component 5 can approach or reach the target water temperature. The control component can control the opening and closing of the water outlet device 2.

[0067] Furthermore, the laundry device also includes a second water inlet assembly 6 suitable for connecting to an external water source 8. The second water inlet assembly 6 is provided with a second water inlet valve 61. The second water inlet assembly 6 is connected to the washing tub 1, and the second water inlet valve 61 is communicatively connected to the control assembly.

[0068] The aforementioned control component can control the opening or closing of the second water inlet valve 61. The second water inlet component 6 also includes a hose, which is mounted on the hose. One end of the hose is connected to an external water source 8, and the other end of the hose can be connected to the washing tub 1 to allow water to enter the washing tub 1 when the second water inlet valve 61 is opened. The control component can control the opening or closing of the second water inlet valve 61.

[0069] The first inlet valve 41 and the second inlet valve 61 can be solenoid valves.

[0070] Furthermore, the basin control panel also features a water pump button and / or a first water inlet valve button.

[0071] The aforementioned water basin control panel allows the controller to open or close the water pump 31 and the first inlet valve 41 when water is being dispensed from the water outlet device 2.

[0072] When the user touches the water pump button on the basin's control panel, the water pump 31 turns on, and heated water enters the water storage tank of the water storage component 5 through the corresponding hose, thereby increasing the water temperature in the storage tank. When the user touches the first water inlet valve button on the basin's control panel, the first water inlet valve 41 opens, and external water enters the water storage tank through the corresponding hose, thereby decreasing the water temperature in the storage tank. The temperature detection device 51 in the storage tank monitors the water temperature in real time and displays it on the basin's control panel. At this time, the temperature of the storage tank is no longer controlled, and water is continuously supplied to the basin 7 through the corresponding hose.

[0073] Example 2

[0074] like Figure 3 The diagram shows a flowchart of a water temperature control method for a laundry washing device, which includes the following steps:

[0075] Step S101: Obtain the target water temperature;

[0076] Step S103: Control the heating device 11 to heat the washing tub 1 according to the target water temperature;

[0077] Step S105: Control the water pump 31 to input the water in the washing tub 1 into the water basin 7.

[0078] In the above steps, the user can input the target water temperature into the basin control panel, and the control component obtains the target water temperature through the basin control panel. By using the heating device 11 of the washing tub 1 to heat the washing tub 1, the water temperature inside the washing tub 1 reaches the target water temperature. Then, the water in the washing tub 1 is pumped into the basin 7 by the water pump 31, thereby realizing the adjustment and control of the inlet water temperature of the basin 7, which is convenient for users.

[0079] Specifically, the target water temperature is the same as the set water temperature of the laundry washing device. For example, the set water temperature of the laundry washing device may include 20℃, 30℃, 40℃, 60℃, and 90℃. Then the target water temperature can also be selected as 20℃, 30℃, 40℃, 60℃, and 90℃, which simplifies the control of the inlet water temperature of the basin 7.

[0080] Furthermore, the water temperature control method for the laundry washing device also includes the following steps:

[0081] Step S201: Control the first inlet valve 41 to open according to the target water temperature so that external water enters the water storage component 5;

[0082] Step S203: Display the water temperature value inside the water storage component 5;

[0083] Step S205: Control the water outlet device 2 to open, so that the water in the water storage component 5 flows into the water basin 7.

[0084] The above steps apply when the user selects room temperature as the target water temperature. When the user selects room temperature, the control component controls the first inlet valve 41 to open, and external water enters the water storage tank of the water storage component 5 through the corresponding hose. The temperature detection device 51 detects the water temperature in the storage tank and displays the water temperature value on the water basin operation panel, allowing the user to intuitively observe the target water temperature. At the same time, the control component controls the water outlet device 2 to open, and water flows into the water basin 7 through the corresponding hose for the user's use.

[0085] Furthermore, the water temperature control method for the laundry washing device also includes the following steps:

[0086] Step S301: Control the second water inlet valve 61 to open according to the target water temperature so that external water enters the washing tub 1;

[0087] Step S303: When the water level reaches the lowest heating water level in the washing tub 1, the heating device 11 is controlled to heat the water to the temperature inside the tub.

[0088] Step S305: Based on the water temperature inside the cylinder, control both the water pump 31 and the first inlet valve 41 to open, so that hot water and external water enter the water storage component 5 respectively, and the water temperature inside the cylinder is higher than the target water temperature.

[0089] Step S307: When the water in the water storage component 5 reaches the target water temperature and the water level reaches the outlet water level, the control will open the outlet device 2.

[0090] When the user selects an adjustable water temperature as the target water temperature, T1 represents the target water temperature, which is the outlet water temperature selected by the user; N1 represents the water temperature difference between the washing tub 1 and T1 when the software controls the heating device 11 to heat the water. This difference is a fixed value. For example, if the user sets T1 to 30℃, the control component controls the water heating device to reach 40℃. In this case, T1+N1=30+10, where T1+N1 is the water temperature inside the tub, and the fixed difference N1 is 10℃.

[0091] The second water inlet valve 61 of the washing machine is opened, and external water enters the washing machine through the corresponding hose. When the water level reaches the minimum heating water level K1 of the washing machine, the heating device 11 is turned on. The software controls the temperature according to T1+N1. When the water temperature sensor of the washing machine detects that the water temperature has reached T1+N1, the heating device 11 stops heating, and the control component controls the water pump 31 to turn on. Hot water enters the water storage tank through the corresponding hose.

[0092] At the same time, the first inlet valve 41 is opened, and external water enters the water storage tank of the water storage component 5 through the corresponding hose. When the temperature detection device 51 in the water storage tank detects that the water temperature in the water storage tank reaches the user's set water temperature T1 and the water level reaches the outlet water level K4, the control component controls the outlet device 2 to open, and introduces water into the water basin 7 through the corresponding hose for the user to use.

[0093] By controlling the water temperature inside the washing tub 1 to be higher than the target temperature, it is easier to control the temperature of the incoming water entering the basin 7. By controlling the water level inside the washing tub 1, it is possible to prevent the heating device 11 from causing the washing tub 1 to burn dry, and also to prevent excessive water from overflowing and causing scalding accidents.

[0094] Furthermore, the water temperature control method for the laundry washing device also includes the following steps:

[0095] When the water level in the washing tub 1 reaches the overflow level, the second water inlet valve 61 is closed; or

[0096] When the water level in the washing tub 1 reaches the first replenishment water level, the second inlet valve 61 is reopened; wherein, the first replenishment water level > the overflow water level > the minimum heating water level.

[0097] The second water inlet valve 61 mentioned above is controlled by the water level of the washing machine. When the water level in the washing tub 1 reaches the overflow water level K2, the second water inlet valve 61 is closed. When the water level reaches the replenishment water level K3, the second water inlet valve 61 is reopened, with water levels K2 > K3 > K1.

[0098] Furthermore, the water temperature control method for the laundry washing device also includes the following steps:

[0099] When the water temperature inside the cylinder exceeds the first preset temperature, the heating device 11 is turned off to prevent waste caused by excessively high temperatures; or

[0100] When the water temperature inside the cylinder is lower than the second preset temperature, the heating device 11 is restarted to prevent the temperature from being too low and causing an excessively long waiting time to reach the target temperature. The second preset temperature is lower than the first preset temperature.

[0101] Specifically, the first preset temperature satisfies T1+N1, and the second preset temperature satisfies T1-N1; where T1 represents the target water temperature and N1 represents the first temperature difference value. The heating device 1 of the washing machine is controlled by a water temperature sensor. When the water temperature sensor detects that the water temperature inside the washing tub 1 reaches T1+N1, the heating device 11 stops heating. When the water temperature sensor detects that the water temperature inside the washing tub 1 drops to T1-N1, the heating device 11 restarts. This facilitates automated control of the water temperature inside the washing tub 1 and makes it more convenient to use.

[0102] Furthermore, the water temperature control method for the laundry washing device also includes the following steps:

[0103] When the water temperature in the water storage component 5 drops to the third preset temperature, the water pump 31 is turned on, and the first inlet valve 41 is closed, thereby controlling the temperature of the water entering the water basin 7 to prevent it from becoming too low.

[0104] When the water temperature in the water storage component 5 rises to the fourth preset temperature, the water pump 31 is turned off and the first water inlet valve 41 is turned on, so that the temperature of the water entering the water basin 7 is controlled to be too high and thus affect its use.

[0105] Specifically, the third preset temperature satisfies: T1-N2, and the second preset temperature satisfies: T1+N2; where T1 represents the target water temperature and N2 represents the second temperature difference value.

[0106] The temperature detection device 51 in the water storage tank of the above-mentioned water storage component 5 can control the opening or closing of the water pump 31 and the first water inlet valve 41. When the temperature detection device 51 detects that the water temperature in the water storage tank drops to T1 - N2, N2 represents the lower limit temperature difference of the water temperature when the water pump 31 is opened. For example, if the user sets 30°C as T1 and the water temperature in the water storage tank drops to 25°C, then N2 is 5°C, and the water pump 31 is opened to supply hot water to the water storage tank, so as to meet the set water temperature value of 30°C by the user. When the water pump 31 is opened and the first water inlet valve 41 is closed, the heated water is injected into the water storage tank through the corresponding hose to increase the water temperature in the water storage tank, so as to reach the target water temperature set by the user. When the temperature detection device 51 detects that the water temperature rises to T1 + N2, the first water inlet valve 41 is opened and the water pump 31 is closed, and the external water is injected into the water storage tank through the corresponding hose to reduce the water temperature in the water storage tank, so as to reach the target water temperature set by the user.

[0107] Further, the water temperature control method of the clothes washing device further includes the following steps:

[0108] When the water level in the water storage component 5 reaches the full load water level, control both the first water inlet valve 41 and the water pump 31 to close; or

[0109] When the water level in the water storage component 5 reaches the second water replenishing water level, control both the first water inlet valve 41 and the water pump 31 to open; where, full load water level > second water replenishing water level > water outlet water level.

[0110] When the water level in the water storage tank of the water storage component 5 reaches the full load water level K5, control the water pump 31 and the first water inlet valve 41 to close, and no longer supply water to the water storage tank. When the water level drops to the water replenishing water level K6, the water pump 31 and the first water inlet valve 41 are opened to supply water to the water storage tank, where water level K5 > K6 > K4.

[0111] Further, the water temperature control method of the clothes washing device further includes the following steps:

[0112] Step S401: Obtain the water inlet time of the water inlet in the water storage component 5;

[0113] Step S403: When the water inlet time reaches the preset time and the water temperature in the water storage component 5 does not reach the target water temperature, when the water temperature in the water storage component 5 reaches the third preset temperature, control the water outlet device 2 of the water basin 7 to open.

[0114] Further, the third preset water temperature satisfies: T1 - N3 < third preset water temperature < T1 + N3, where, T1 represents the target water temperature and N3 represents the third temperature difference value.

[0115] If the temperature detection device 51 in the water storage tank of the aforementioned water storage component 5 detects that the water temperature cannot reach the user-set target water temperature T1 within time t1, then the outlet water temperature will be adjusted to between T1-N3 and T1+N3. As long as the water temperature is within this range, the water storage tank can supply water to the water basin 7 through the corresponding hose. N3 represents the allowable fluctuation difference in the outlet water temperature after time t1. For example, if the water temperature cannot reach the target temperature of 30℃ within a certain time, the outlet water temperature will become a certain range, 28℃-32℃, where N3 is 2℃, and water can still be supplied to the water basin 7, thus improving the flexibility of the inlet water temperature control of the water basin 7.

[0116] Figure 4 As shown, the user sets the water temperature to T1, then opens the second water inlet valve 61, waits for the water level in the washing machine drum to reach K1, turns on the heating device 11, the water temperature in the drum reaches T1+N1, turns off the heating device 11, turns on the water pump 31, then opens the first water inlet valve 41, the temperature detection device 51 in the water storage component 5 detects that the water temperature has reached K1 and the water level has reached K4, turns on the water storage component, and supplies water to the water supply device 2.
