[0043] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0044] The refrigeration device of the present invention may be a refrigerator 100, a freezer or a commercial display cabinet, etc. The specific implementation of the present invention will be described below by taking the refrigerator 100 as an example.

[0045] Reference Figure 1 , illustrates a refrigerator 100 according to an embodiment of the present invention. The refrigerator 100 includes a housing 1, a storage chamber 2 formed in the housing 1, and a storage chamber door 3 for opening and closing the storage chamber 2.

[0047] In this embodiment, the refrigerator 100 further includes an ice maker 5 disposed in the housing 1 or the storage compartment door 3.

The water injection waterway includes an ice maker water injection port corresponding to the ice maker 5.

[0048] In this embodiment, the refrigerator 100 further includes an automatic water filling kettle 7 disposed on the cabinet 1 or the storage compartment door 3. Preferably, the automatic water filling kettle 7 is disposed in the dispenser chamber 4 so as to be removable. The user can take out the automatic water filling kettle 7 and use it outside the refrigerator 100. The water filling water path includes an automatic water filling kettle water filling port corresponding to the automatic water filling kettle 7. The automatic water filling kettle water filling port and the external water taking water filling port can be disposed on the top of the dispenser chamber 4 and arranged side by side and spaced along the width direction of the dispenser chamber 4.

[0049] Reference Figure 2 and Figure 3 , illustrates a control method of a refrigerator 100 according to an embodiment of the present invention. The control method includes:

[0050] When a water injection signal is obtained, the rear-stage water valve of the water injection water circuit of the refrigerator 100 is opened, the water injection water circuit of the refrigerator 100 includes a main water valve, the rear-stage water valve and a water pipe, the water inlet end of the main water valve is connected to the external water source of the refrigerator 100 through a water pipe, the water outlet end of the main water valve and the water inlet end of the rear-stage water valve are connected through a water pipe, and the water outlet end of the rear-stage water valve is connected to the external water inlet of the refrigerator 100, and / or the water inlet of the ice maker, and / or the water inlet of the automatic water filling kettle through a water pipe;

[0051] When the rear-stage water valve is opened for a preset time, the main water valve is opened.

[0052] In this embodiment, the water outlet of the rear-stage water valve may include a first water outlet, a second water outlet and a third water outlet, the first water outlet of the rear-stage water valve is connected to the external water inlet through a water pipe, the second water outlet of the rear-stage water valve is connected to the ice maker water inlet through a water pipe, and the third water outlet of the rear-stage water valve is connected to the automatic water filling kettle water inlet through a water pipe. In this way, the connection between the rear-stage water valve and the three water inlets can be achieved by setting a rear-stage water valve with one inlet and three outlets.

[0053] Reference Figure 4 In another embodiment of the present invention, the rear-stage water valve may include a primary water valve and a secondary water valve, the water inlet end of the primary water valve is connected to the main water valve through a water pipe, the water outlet end of the primary water valve includes a first water outlet and a second water outlet, the first water outlet of the primary water valve is connected to the external water inlet through a water pipe, the second water outlet of the primary water valve is connected to the water inlet end of the secondary water valve through a water pipe, the secondary water valve includes a first water outlet and a second water outlet, the first water outlet of the secondary water valve is connected to the ice maker water inlet through a water pipe, and the second water outlet of the secondary water valve is connected to the automatic water filling kettle water inlet through a water pipe. With such an arrangement, the connection between the rear-stage water valve and the three water inlets can be achieved by setting two rear-stage water valves with one inlet and two outlets.

[0054] In this embodiment, the water injection signal refers to a signal requiring the water injection port to discharge water outward.

[0055] Correspondingly, the water injection signal of the external water inlet is a signal that requires the external water inlet to discharge water. For example, when a user takes a cup to collect water from the external water inlet, the water injection signal of the external water inlet can be sent to the refrigerator 100 by voice, touch or button. After the refrigerator 100 obtains the water injection signal, it can control the water path between the external water inlet and the external water source to be connected, so that the external water inlet discharges water outward, thereby enabling the user to collect water from the external water inlet.

[0056] The water injection signal of the ice maker water injection port refers to a signal that requires the ice maker water injection port to discharge water. For example, when the refrigerator 100 detects that the ice cubes in the ice storage box 6 are less than a preset amount, a water injection signal of the ice maker water injection port can be generated. After the refrigerator 100 obtains the water injection signal, the water path between the ice maker water injection port and the external water source can be controlled to be connected, so that the ice maker water injection port discharges water outward, thereby realizing water injection into the ice maker 5.

[0057] The water injection signal of the water injection port of the automatic water injection kettle refers to a signal that requires the water injection port of the automatic water injection kettle to discharge water outward. For example, when the refrigerator 100 detects that the water in the automatic water injection kettle 7 is lower than a preset amount, a water injection signal of the water injection port of the automatic water injection kettle can be generated. The refrigerator 100 obtains the water injection signal port and can control the water path between the water injection port of the automatic water injection kettle and the external water source to be connected, so that the water injection port of the automatic water injection kettle discharges water outward, thereby filling the automatic water injection kettle 7 with water.

[0058] The specific duration corresponding to the preset time can be set as needed, for example, 2 seconds.

[0059] The external water source may be tap water in the user's home. The main water valve may be arranged outside the refrigerator 100. The rear-stage water valve is arranged inside the refrigerator 100. With such arrangement, the main water valve can directly bear the water pressure from the external water source. When water injection is required, the rear-stage water valve is opened first, and at least one water path connected to the water outlet of the rear-stage water valve is in a through state, and then the main water valve is opened. This can effectively reduce the impact of the water pressure of the external water source on the rear-stage water valve, and avoid the rear-stage water valve from being damaged by multiple impacts of high water pressure, thereby increasing the service life of the rear-stage water valve. Due to the different positions of the main water valve and the rear-stage water valve, the main water valve bears higher water pressure and greater impact force, and even if the main water valve is damaged, it is easier to replace.

[0060] The main water valve adopts a water valve structure that can withstand higher water pressure and is more resistant to water flow impact. Compared with the main water valve, the subsequent water valve can adopt a water valve structure with lower water pressure bearing capacity and lower water flow impact resistance. With this arrangement, the subsequent water valve can use an ordinary water valve, which can reduce the number of water valves with high pressure resistance and impact resistance requirements, thereby reducing production costs.

[0061] Reference Figure 3 , further, in this embodiment, it also includes:

[0062] When a signal to stop water injection is obtained, closing the main water valve;

[0063] When the main water valve is closed for a preset time, the subsequent water valve is closed.

[0064] Such an arrangement enables the main water valve to first intercept the external water source and then close the subsequent water valve, effectively reducing the impact of the water pressure of the external water source on the subsequent water valve, thereby increasing the service life of the subsequent water valve.

[0065] Reference Figure 3 , further, in this embodiment, it also includes:

[0066] When the water injection signal of the external water inlet is obtained, the water injection signal of the ice maker water injection port and / or the automatic water injection kettle water injection port is also obtained;

[0067] The water outlet end of the rear-stage water valve is controlled to open only the water outlet corresponding to the external water intake and injection port.

[0068] With such a setting, when multiple water injection signals are obtained at the same time, the water supply to the external water intake port is given priority to meet the water intake needs of users, and it is avoided that when the external water intake port is supplying water to the outside, water flows out of other water injection ports, resulting in the water output volume and water output speed of the external water intake port being unable to meet user needs.

[0069] Reference Figure 3 , further, in this embodiment, when the water injection signal of the water injection port of the ice maker is obtained, the water injection signal of the water injection port of the automatic water injection kettle is also obtained;

[0070] The water outlet of the water outlet end of the rear-stage water valve is controlled to open only the water outlet corresponding to the water injection port of the ice maker.

[0071] With such an arrangement, it is possible to obtain water injection signals from the ice maker water injection port and the automatic water injection kettle water injection port at the same time, prioritize the water supply to the outside of the ice maker water injection port to meet the user's demand for ice, and avoid water flowing out of the automatic water injection kettle water injection port when water is flowing out of the ice maker water injection port, resulting in the water output volume and water output speed of the ice maker water injection port being unable to meet the demand.

[0072] Reference Figure 3 , further, in this embodiment, it also includes:

[0073] When the water outlet of the water outlet end of the rear-stage water valve corresponding to the water inlet of the ice maker or the water inlet of the automatic water filling kettle is opened, a water injection signal of the external water inlet is obtained;

[0074] Close the main water valve;

[0075] When the main water valve is closed for a preset time, the water outlet of the water outlet end of the rear-stage water valve corresponding to the water injection port of the ice maker or the water injection port of the automatic water injection kettle is closed, and the water outlet of the water outlet end of the rear-stage water valve corresponding to the external water injection port is opened;

[0076] When the water outlet at the water outlet end of the rear-stage water valve corresponding to the external water intake and injection port is opened for a preset time, the main water valve is opened.

[0077] Such an arrangement can give priority to ensuring the outward water supply from the external water intake and injection port, and can also ensure that when the outward water supply from other water injection ports is switched to the outward water supply from the external water intake and injection port, the external water source is first intercepted by the main water valve, and then the outlet opened at the outlet end of the subsequent water valve is switched. After the switching is completed, the main water valve is opened again to allow water to flow to the switched outlet, thereby reducing the impact of water pressure on the subsequent water valve and increasing the service life of the subsequent water valve.

[0078] Reference Figure 3 , further, in this embodiment, it also includes:

[0079] When the water outlet of the water outlet end of the rear-stage water valve corresponding to the external water inlet is opened, a water injection signal from the ice maker water inlet or the automatic water injection kettle water inlet is obtained;

[0080] When a signal indicating that water filling from the external water inlet is completed is obtained, closing the main water valve;

[0081] When the main water valve is closed for a preset time, the water outlet at the water outlet end of the rear-stage water valve corresponding to the external water inlet is closed, and the water outlet at the water outlet end of the rear-stage water valve corresponding to the ice maker water inlet or the automatic water kettle water inlet is opened.

[0082] Such an arrangement can give priority to ensuring the water supply to the outside from the external water intake and injection port, and can also reduce the impact of water pressure on the subsequent water valve when the outlet port opened at the outlet end of the subsequent water valve is switched.

[0083] Reference Figure 3 , further, in this embodiment, it also includes:

[0084] When the water outlet of the water outlet end of the rear-stage water valve corresponding to the water inlet of the automatic water filling kettle is opened, a water injection signal of the water inlet of the ice maker is obtained;

[0085] Close the main water valve;

[0086] When the main water valve is closed for a preset time, the water outlet of the water outlet end of the rear-stage water valve corresponding to the water inlet of the automatic water filling kettle is closed, and the water outlet of the water outlet end of the rear-stage water valve corresponding to the water inlet of the ice maker is opened;

[0087] When the water outlet at the water outlet end of the rear-stage water valve corresponding to the water filling port of the ice maker is opened for a preset time, the main water valve is opened.

[0088] Furthermore, in this embodiment, it also includes:

[0089] When the water outlet of the water outlet end of the rear-stage water valve corresponding to the water injection port of the ice maker is opened, a water injection signal of the water injection port of the automatic water injection kettle is obtained;

[0090] When a signal is obtained that the water filling of the ice maker water filling port is completed, closing the main water valve;

[0091] When the main water valve is closed for a preset time, the water outlet of the water outlet end of the rear-stage water valve corresponding to the water inlet of the ice maker is closed, and the water outlet of the water outlet end of the rear-stage water valve corresponding to the water inlet of the automatic water filling kettle is opened.

[0092] Such an arrangement can ensure that when both the ice maker 5 and the automatic water filling kettle 7 need water, water supply to the ice maker 5 is given priority, and can also reduce the impact of water pressure on the subsequent water valve when the outlet of the subsequent water valve is switched.

[0093] Furthermore, in this embodiment, the refrigerator 100 also includes a memory and a processor. The refrigerator 100 also includes a memory and a processor. The memory stores a computer program that can be run on the processor. When the processor executes the computer program, the steps in the control method of the refrigerator 100 described in any of the above embodiments are implemented.

[0094] An embodiment of the present invention further provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps in the control method of the refrigerator 100 described in any of the above embodiments.

[0095] In summary, the refrigeration device of the present invention can solve the problem that when the water in the water storage box is used up, the user needs to take the water storage box out of the refrigerator 100 to add water, which is inconvenient to use. The technical solution of the present application can realize more convenient water supply for the refrigeration device while avoiding the impact of high water pressure on the rear-stage water valve, thereby increasing the service life of the rear-stage water valve, ensuring the highest priority water supply to the external water inlet and the second priority water supply to the ice maker water inlet, and reducing the impact of water pressure on the rear-stage water valve when the outlet of the rear-stage water valve is switched.
