[0036] 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.

[0037] In one embodiment of the present invention, a refrigeration appliance is provided. The refrigeration appliance may be a refrigerator, a freezer, a commercial display cabinet, etc. In this embodiment, the refrigeration appliance is a refrigerator, and the specific embodiment of the present invention is described below using a refrigerator as an example.

[0038] Reference Figure 1 and Figure 2 The refrigerator 100 may include a housing 1, a refrigerating chamber 2 formed in the housing 1, a freezing chamber, a refrigerating door 3 for opening and closing the refrigerating chamber 2, and a freezing door for opening and closing the freezing chamber.

[0039] The refrigerator 100 includes a water filter assembly 4, including a filter 44, and a water storage tank 45, which is arranged below the filter 44 and is used to store water dripping from the filter 44; a heating element, which is used to heat the water storage tank 45 to evaporate the water in the water storage tank 45; and a water absorption layer, which is coated on the outside of the filter 44 and is used to absorb the water leaked from the filter 44 and the water evaporated from the water storage tank 45.

[0040] In this embodiment, the water filter assembly 4 is disposed on the refrigerator door 3. The refrigerator door 3 may be provided with a water outlet, one end of the filter 44 is connected to the user's household tap water through a water pipe, and the other end of the filter 44 is connected to the water outlet through a water pipe to provide relatively pure water to the water outlet.

[0041] The water outlet may be disposed on the exterior side of the refrigerating door 3 or on the inner side of the refrigerating door 3. For example, the refrigerating door 3 is provided with a dispenser chamber, the dispenser chamber opens outward, the water outlet may be disposed in the dispenser chamber, and the user may directly take water from the water outlet in the dispenser chamber without opening the refrigerating door 3.

[0042] Of course, in other embodiments of the present invention, the filter 44 may also be disposed on the housing 1. The refrigerator 100 may also be provided with an ice maker, and the filter 44 may supply water to the ice maker.

[0043] Preferably, in this embodiment, the heating element is a heating wire, and the heating wire can be pre-buried in the bottom of the water storage tank 45.

[0044] Preferably, in this embodiment, the water-absorbing layer completely covers the outside of the filter 44 to fully absorb the water leaked from the filter 44. The water-absorbing layer is formed of absorbent paper with good water absorption, such as 46gsm absorbent paper.

[0045] When the water leaking from the filter 44 is small, it will be completely absorbed by the water absorption layer and will not flow out. When the water leaking from the filter 44 is large, the water absorption layer at the leakage point will not have time to absorb all the leaking water, and the leaking water will drip into the water storage tank 45 below the filter 44, and the leaking water will be stored in the water storage tank 45 to prevent the leaking water from flowing around. In this way, the water absorption layer and the water storage tank 45 can form multiple protections, fully absorb and store the water leaking from the filter 44, and prevent the leaking water from flowing around.

[0046] The water in the water storage tank 45 is evaporated by heating with the heating element, so that the water absorption layer outside the filter 44 fully absorbs the evaporated water vapor, which not only can increase the overall water storage capacity of the water storage tank 45 and the water absorption layer, but also can concentrate the water in the water absorption layer, so that the area around the filter 44 component is always kept dry to avoid affecting other components. In addition, the user can remove the leaked water by replacing the water absorption layer at a later time, which is convenient and quick.

[0047] Preferably, in this embodiment, the water-absorbing layer is adhered to the outer surface of the filter 44 by gluing, such as using PET adhesive.

[0048] Reference Figure 2 Furthermore, in this embodiment, the water filter assembly 4 also includes:

[0049] A water leakage detection device, which is used to detect whether the filter 44 is leaking;

[0050] A controller is communicatively connected with the water leakage detection device and the heating element, and controls the heating element to turn on according to the water leakage information transmitted by the water leakage detection device.

[0051] With such an arrangement, the heating element can be activated in time when water leakage of the filter 44 is detected, ensuring that the water absorption layer can fully absorb the leaked water, so that the area around the filter 44 component is always kept dry.

[0052] Furthermore, in this embodiment, the water leakage detection device includes: an induction coil, which can send radio frequency signals and is connected to the water absorption layer. When the induction coil is immersed in water, the transmission of the radio frequency signal of the induction coil changes; a reader / writer, which is communicatively connected to the controller and can receive the radio frequency signal sent by the induction coil; the controller obtains the water leakage information of the filter 44 based on the radio frequency signal received by the reader / writer.

[0053] If the filter 44 leaks water, the water-absorbing layer will absorb the water leaking from the filter 44, and the water-absorbing layer will become wet after absorbing the water, thereby soaking the induction coil connected to the water-absorbing layer.

[0054] Preferably, in this embodiment, the water leakage detection device may be provided with a chip connected to the induction coil, and the chip may store ID information. When the induction coil is not immersed in water, the chip may control the induction coil to send a radio frequency signal. When the induction coil is immersed in water, the chip may control the induction coil to send another different radio frequency signal. According to the difference in the radio frequency signal received by the reader, it can be known whether the induction coil is immersed in water, thereby knowing whether the filter 44 is leaking.

[0055] In other embodiments of the present invention, the induction coil in a non-water-immersed state can also be set to be open-circuited, that is, the induction coil in a non-water-immersed state cannot transmit a radio frequency signal. When the induction coil is immersed in water, the induction coil can send a radio frequency signal carrying ID information to the reader through the conductive effect of water. If the reader receives the radio frequency signal sent by the induction coil, it can be known that the induction coil is immersed in water.

[0056] Reference Figure 2 Furthermore, in this embodiment, a plurality of induction coils may be arranged at different positions of the filter 44 to detect water leakage of the filter 44 .

[0057] Such an arrangement can realize accurate detection of water leakage of the filter 44 .

[0058] Furthermore, in this embodiment, the water filter component 4 also includes a water supply component and a water valve, and the water valve is used to control the water supply component to supply water to the filter 44. The water valve is communicatively connected to the controller, and the controller controls the opening and closing of the water valve according to the water leakage information.

[0059] With such an arrangement, it is possible to stop supplying water to the filter 44 in time when the filter 44 leaks, thereby reducing the amount of water leaking from the filter 44 and avoiding water accumulation around the filter 44 .

[0060] Furthermore, in this embodiment, the water filter assembly 4 further includes a prompt module, the prompt module is communicatively connected to the controller, and the controller controls the prompt module to output prompt information of the filter 44 leaking and / or replacing the filter 44 according to the water leakage information. The prompt module can be a display screen or the like.

[0061] Such an arrangement can promptly remind the user when the filter 44 leaks, and prompt the user to repair or replace the filter 44 in time.

[0062] Reference Figure 2Further, in this embodiment, the water filter assembly 4 includes a first shell 41 and a second shell 42 that are arranged opposite to each other, a receiving chamber 43 is formed between the first shell 41 and the second shell 42, and the filter 44 and the water absorption layer are arranged in the receiving chamber 43. The water storage tank 45 is integrally arranged with the first shell 41 or the second shell 42. The heating element is arranged in the water storage tank 45. The first shell 41 or the second shell 42 can be integrally formed with the water storage tank 45 by adsorption or injection molding, which can avoid the generation of seams and prevent water leakage at the water storage tank.

[0063] The accommodating chamber 43 is set in a closed manner to prevent the water vapor evaporated from the water storage tank 45 or the heat of the heating wire from diffusing outside the accommodating chamber 43. The accommodating chamber 43 of the accommodating filter 44 forms a relatively closed environment, which can prevent moisture leakage in the accommodating chamber 43, prevent condensation in other components of the refrigeration appliance, and isolate the heat generated by the heating element in the accommodating chamber 43, so as to prevent the heat leakage in the accommodating chamber 43 from affecting other components or affecting the user's experience.

[0064] Reference Figure 2 Further, in this embodiment, the first housing 41 or the second housing 42 is formed with an opening 46 corresponding to the accommodating cavity 43, and the water filter assembly 4 further includes a cover for opening and closing the opening 46, and the filter 44 is detachably disposed in the accommodating cavity 43 and can be taken out through the opening 46. Such a configuration can facilitate the user to replace or repair the filter 44, and replace the water absorption layer of the filter 44.

[0065] Reference Figure 1 and Figure 2 Preferably, in this embodiment, the refrigeration door 3 includes a door shell 31 and a door lining 32, and an accommodating space is formed between the door shell 31 and the door lining 32. The door lining 32 is provided with an installation opening matched with the first shell 41, the first shell 41 is provided at the installation opening, the second shell 42 is provided between the door shell 31 and the door lining 32, the first shell 41 is formed with an opening 46 corresponding to the accommodating cavity 43, and the cover body is installed with the first shell 41, the second shell 42 and the water storage tank 45 are provided in an integrated manner.

[0066] Reference Figure 2 and Figure 3 Furthermore, in this embodiment, a control method of the water filter assembly 4 is also provided, comprising:

[0067] Check whether the filter 44 is leaking;

[0068] When the information that the filter 44 is leaking is obtained, the water valve is controlled to close, and the heating element is controlled to start heating the water storage tank 45. The water valve is used to control the water supply component to supply water to the filter 44. The water storage tank 45 is used to store water dripping from the filter 44. The outside of the filter 44 is coated with a water absorption layer, and the water absorption layer can absorb the water leaked from the filter 44 and the water evaporated from the water storage tank 45.

[0069] With such an arrangement, after detecting that the filter 44 is leaking, the water supply to the filter 44 can be stopped in time, and the heating wire can be controlled in time to start evaporating the water in the water storage tank 45, ensuring that the water absorption layer can fully absorb the leaked water, so that the area around the filter 44 component is always kept dry.

[0070] Further, in this embodiment, the control method of the water filter assembly 4, "detecting whether the filter 44 is leaking" includes:

[0071] The reader is controlled to receive a radio frequency signal, and the induction coil sends the radio frequency signal. The induction coil is connected to the water absorbing layer. When the induction coil is immersed in water, the sending of the radio frequency signal of the induction coil changes.

[0072] The water leakage information of the filter 44 is obtained according to the radio frequency signal received by the reader / writer.

[0073] With such an arrangement, it is possible to accurately detect the water leakage of the filter 44 by sending a radio frequency signal, which is a wireless communication method.

[0074] Furthermore, in this embodiment, the control method of the water filter assembly 4 further includes: recording the heating time of the heating element, and when the heating time reaches a preset time, controlling the heating wire to turn off. Preferably, the heating time of the heating element is 8 minutes. Such a setting can ensure that the water in the water storage tank is fully evaporated, and at the same time, avoid unnecessary energy loss caused by the heating wire being turned on for too long.

[0075] Furthermore, in this embodiment, the control method of the water filter assembly 4 further includes:

[0076] When the heating wire is turned off, a prompt message indicating that the filter 44 is leaking and / or the filter 44 needs to be replaced is output.

[0077] Such a configuration can promptly remind the user of water leakage in the filter 44, prompt the user to repair or replace the filter 44 in time, and can also prevent the user from being burned by hot air.

[0078] Furthermore, the present invention also 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 water filter assembly 4 described in any of the above embodiments.

[0079] In summary, the water filter assembly 4, refrigeration appliance, control method and medium of the water filter assembly 4 in the present invention can solve the problem in the prior art that when the filter 44 leaks, the water leaking from the filter 44 may flow around, causing damage to other surrounding components and affecting the user's use. The technical solution in this application can form a water-absorbing layer and a water storage tank 45 with multiple protections to fully absorb and store the water leaking from the filter 44 and prevent the leaking water from flowing around. The water in the water storage tank 45 is heated by a heating element to evaporate the water, so that the water-absorbing layer outside the filter 44 fully absorbs the evaporated water vapor, increasing the overall water storage capacity of the water storage tank 45 and the water-absorbing layer, so that the water is concentrated in the water-absorbing layer, so that the filter 44 component is always kept dry to avoid affecting other components, and the user can remove the leaking water by replacing the water-absorbing layer, which is convenient and quick.
