[0045] The utility model will be described in detail below in combination with the embodiments shown in the drawings. However, the embodiments do not limit the utility model, and the changes in mechanism, method or function made by those skilled in the art based on the embodiments are included in the protection scope of the utility model.

[0046] The terms such as "upper", "lower", "left", "right", "front", "back", etc. used herein to indicate spatial relative positions are for the purpose of facilitating illustration to describe the relationship of one feature relative to another feature as shown in the drawings. It can be understood that the terms of spatial relative positions can be intended to include different orientations other than the one shown in the drawings, and should not be construed as limiting the claims. In addition, the descriptive word "horizontal" used herein is not completely equivalent to along the direction perpendicular to the gravity direction, and a certain angle of inclination is allowed.

[0047] As shown in Figures 1-2 The first embodiment of the present application provides a refrigeration equipment 100, which comprises a cabinet 20, a compartment 30 formed in the cabinet 20, and a door body 50 for opening and closing the compartment 30.

[0048] The cabinet 20 is generally in a box structure with a back plate, a top plate, a bottom plate, a left side plate and a right side plate. One or more inner containers are sleeved in the interior of the cabinet 20 and are spaced apart from the cabinet 20 to form a foaming space between the cabinet 20 and the inner container. The compartment 30 is formed by the inner container, and the foaming space can be filled with foaming material having a heat preservation effect.

[0049] The door body 50 can be connected to the cabinet 20 by a hinge to be able to rotate relative to the cabinet 20. A user opens and closes the compartment 30 by rotating the door body 50. When it is needed to store food in the compartment 30 or to take out the food in the compartment 30, the user rotates the door body 50 to open the compartment 30. When the compartment 30 is closed, the compartment 30 is basically in a closed state, and the user cannot take or place articles.

[0050] In the refrigeration equipment 100, the number of the compartment 30 and the door body 50 is more than one, for example, Figures 1-2 As shown in the refrigeration equipment 100, which is a refrigerator, comprises two compartments 30 and two door bodies 50 corresponding to the two compartments 30. According to different set refrigeration temperatures, the compartments 30 can be a refrigeration compartment 31, a freezing compartment 32 and a variable temperature compartment. Figure 1 As shown in the refrigeration equipment 100, which comprises a refrigeration compartment 31 and a freezing compartment 32.

[0051] The refrigeration equipment 100 further comprises a refrigeration system for refrigerating the compartment 30. The refrigeration system comprises an evaporator, a compressor, a condenser, a throttling element and the like. The compressor, the condenser, the throttling element and the evaporator are connected in series to form a circulation pipeline. Under the action of the compressor, the refrigerant flows in the circulation pipeline and absorbs heat and releases heat based on phase change, and then exchanges heat with air at the evaporator to prepare cold air required by the compartment 30.

[0052] Generally, the user stores food in the chamber 30, which will carry harmful bacteria, and external bacteria will also enter the chamber 30 when the user opens and closes the door body 50. Although the low-temperature environment in the chamber 30 can reduce the activity of bacteria, it cannot completely eliminate them. The bacteria in the chamber 30 will contaminate all the food stored in the chamber 30, and if the user does not take measures to eliminate bacteria before eating, there is a risk of food poisoning.

[0053] To solve the above problems, the refrigeration equipment 100 provided by the utility model further comprises a sterilization module 10, which is located in the chamber 30 and can eliminate the bacteria existing in the chamber 30, greatly reducing the concentration of bacteria in the chamber 30. In addition to bacteria, the sterilization module 10 can also eliminate viruses existing in the chamber 30.

[0054] Continue to combine Figures 3-7 As shown in the figure, the sterilization module 10 comprises a water storage cavity 1 and a first ionization assembly 2 located at least partially in the water storage cavity 1. The first ionization assembly 2 can ionize the water in the water storage cavity 1, ionizing the water molecules in the water storage cavity 1 into various particles with strong oxidizing properties.

[0055] The sterilization module 10 further comprises an atomizing piece 3 and a second ionization assembly 4. The atomizing piece 3 is used to atomize the water in the water storage cavity 1 into water mist after being ionized by the first ionization assembly 2. It can be imagined that the water mist contains particles with strong oxidizing properties. The water mist emitted by the atomizing piece 3 will flow through the second ionization assembly 4. After the second ionization assembly 4 ionizes the water mist emitted by the atomizing piece 3 for the second time, the concentration of the particles with strong oxidizing properties in the water mist particles will be greatly increased. The above-mentioned particles with strong oxidizing properties can destroy the proteins, fats, carbohydrates, DNA, and RNA tissues of organisms after drifting to various places in the chamber 30, thereby eliminating bacteria and reducing the activity of viruses.

[0056] As Figure 2 shown, the refrigeration equipment 100 comprises an air duct cover plate 40 located in the chamber 30. The air duct cover plate 40 divides the chamber 30 into a storage space 33 and a refrigeration cabin 34. The storage space 33 is used to store food and is located in front of the air duct cover plate 40. The refrigeration cabin 34 is located behind the air duct cover plate 40. The above-mentioned evaporator (not shown in the figure) is located in the refrigeration cabin 34. The air duct cover plate 40 is formed with an air outlet 401 and an air return 402 that communicate the refrigeration cabin 34 and the storage space 33. The refrigeration equipment 100 further comprises a fan (not shown in the figure) arranged in the refrigeration cabin 34. Under the action of the fan, the cold air around the evaporator can become cold wind and flow from the refrigeration cabin 34 into the storage space 33 through the air outlet 401 to reduce the temperature in the storage space 33. The gas in the storage space 33 can enter the refrigeration cabin 34 through the air return 402. In this way, a circulating air path can be formed between the refrigeration cabin 34 and the storage space 33.

[0057] The sterilization module 10 is arranged near the air outlet 401. When the fan causes the cold air in the refrigeration compartment 34 to flow into the storage space 33 through the air outlet 401, the water mist particles generated by the sterilization module 10 will be wrapped into the cold air and fall to various parts of the compartment 30.

[0058] After the water molecules are ionized, hydrogen ions, hydroxyl ions, hydrogen peroxide and other particles with sterilization effect can be generated. In this embodiment, the first ionization assembly 2 is used to ionize the water in the water storage cavity 1 into at least hydroxyl ions, and the second ionization assembly 4 is used to ionize the water mist with hydroxyl ions again to increase the content of hydroxyl ions in the water mist. It can be seen that the sterilization module 10 of this embodiment can generate water mist with high concentration of hydroxyl ions. The hydroxyl ions can react with proteins, nucleic acid molecules in microbial cells and fatty acids in cell walls, which can quickly and effectively eliminate bacteria and viruses and produce water, which is safe and pollution-free.

[0059] The second ionization assembly 4 includes a first electrode 41 and a second electrode 42 arranged opposite to each other, an ionization cavity 43 between the first electrode 41 and the second electrode 42, a plurality of first conductive needles 44 extending from the first electrode 41 into the ionization cavity 43, and a plurality of second conductive needles 45 extending from the second electrode 42 into the ionization cavity 43. The ionization cavity 43 has an inlet 431 and an outlet 432 communicating with the outside, and the atomization member 3 is arranged at the inlet 431.

[0060] The water mist emitted by the atomizer can enter the ionization cavity 43 from the inlet 431 and be discharged outward from the outlet 432 after flowing through the ionization cavity. In the process of the water mist flowing through the ionization cavity 43, the first electrode 41, the second electrode 42, the plurality of first conductive needles 44 and the plurality of second conductive needles 45 contact the water mist, thereby ionizing the water mist to increase the content of strong oxidizing particles in the water mist. The plurality of first conductive needles 44 and the plurality of second conductive needles 45 can sufficiently contact the water mist to effectively ionize the water mist.

[0061] The sterilization module 10 further includes two insulating members 46 arranged between the first electrode 41 and the second electrode 42. The two insulating members 46 are arranged in a spaced manner, and the first electrode 41, the first electrode 41 and the two insulating members 46 form the ionization cavity 43.

[0062] In this embodiment, the sterilization module 10 further includes a water guide member 5. The atomization member 3 can not directly contact the water in the water storage cavity 1, but the water guide member 5 guides the water in the water storage cavity 1 to the atomization member 3. Specifically, one end of the water guide member 5 is located in the water storage cavity 1 to be in contact with the water in the water storage cavity 1, and the other end is located at the atomization member 3.

[0063] The water guide 5 can be made of water-absorbing cotton, one end of which is in contact with the water in the water storage cavity 1, and the other end is located at the atomizing member 3. Under the capillary action, the water in the water storage cavity 1 can be guided to the atomizing member 3 at a proper speed through the water-absorbing cotton.

[0064] The first ionizing assembly 2 comprises oppositely arranged first and second electrode plates 21 and 22, a plurality of third conductive pins 23 extending from the first electrode plate 21 toward the second electrode plate 22, and a plurality of fourth conductive pins 24 extending from the second electrode plate 22 toward the first electrode plate 21. The water guide 5 is located between the first and second electrode plates 21 and 22. The first and second electrode plates 21 and 22 can ionize the water located therebetween, and the plurality of third and fourth conductive pins 23 and 24 can sufficiently contact the water in the water storage cavity 1 to effectively ionize the water.

[0065] The sterilization module 10 further comprises a flow promoting member 6 for promoting the flow of the water in the water storage cavity 1. Under the action of the flow promoting member 6, the water in the water storage cavity 1 can sufficiently flow, thereby improving the ionization efficiency of the first ionizing assembly 2.

[0066] In the embodiment, the flow promoting member 6 is a water pump located outside the housing 7. The water inlet and outlet of the water pump are both in communication with the water storage cavity 1, and can be arranged at opposite sides of the water storage cavity 1. When the water pump is working, the water in the water storage cavity 1 enters the water pump from the water inlet, and then flows into the water storage cavity 1 from the water pump through the water outlet, so that the water in the water storage cavity 1 can sufficiently flow.

[0067] In other embodiments, the flow promoting member 6 can also be a stirring element for stirring the water in the water storage cavity 1.

[0068] As can be seen from the above description, when the sterilization module 10 is working, the water in the water storage cavity 1 is scattered outward in the form of water mist. The sterilization module 10 further comprises a housing 7 surrounding the water storage cavity 1. In order to replenish the water in the water storage cavity 1, the sterilization module 10 further comprises a water box 8 for storing water. The housing 7 is provided with a communication hole 71 in communication with the water storage cavity 1 and the interior of the water box 8. The sterilization module 10 comprises a control structure 9 for controlling whether the communication hole 71 and the water storage cavity 1 are in communication.

[0069] Before use, the user can fill the water storage cavity 1 and the water box 8 with water. When the water in the water storage cavity 1 is insufficient after the sterilization module 10 has worked for a period of time, the control structure 9 is opened, so that the communication hole 71 and the water storage cavity 1 are in communication, and thus the water in the water box 8 can flow into the water storage cavity 1. When the water storage cavity 1 is filled with water, the control structure 9 is closed, and the communication between the communication hole 71 and the water storage cavity 1 is disconnected, so that the water in the water box 8 cannot flow into the water storage cavity 1.

[0070] Specifically, the control structure 9 comprises a control rod 91 located in the water storage cavity 1 and rotationally connected to the shell 7, the control rod 91 is provided with a float part 92 and a blocking part 93, the density of the float part 92 is less than that of water, thus the float part 92 always tends to float on the water surface, when the water level in the water storage cavity 1 changes, the float part 92 can move up and down accordingly, so that the control rod 91 rotates and the position of the blocking part 93 changes. The blocking part 93 can move to a position to block the communication hole 71, so that the communication hole 71 cannot communicate with the water storage cavity 1; the blocking part 93 can also move away from the position to block the communication hole 71, so that the communication hole 71 can communicate with the water storage cavity 1.

[0071] The control structure 9 is configured to: when the water level in the water storage cavity 1 is not lower than a preset height, the blocking part 93 blocks the communication hole 71; when the water level in the water storage cavity 1 is lower than the preset height, the blocking part 93 opens the communication hole 71.

[0072] The water box 8 is specifically located above the water storage cavity 1, so that the water in the water box 8 can flow into the water storage cavity 1 through the communication hole 71 under the action of gravity.

[0073] As shown in Figure 6 , the communication hole 71 is located above the water storage cavity 1, the water storage cavity 1 contains water, and the water level is at the above-mentioned preset height, the float part 92 floats on the water surface, under the action of the float part 92, the blocking part 93 cannot move and can only block the communication hole 71 by abutting against the shell 7, so that the water in the water box 8 cannot enter the water storage cavity 1 through the communication hole 71.

[0074] As shown in Figure 7 , compared with Figure 6 , Figure 7 , the water level in the water storage cavity 1 drops by a certain height, when the water level drops, the position of the float part 92 also drops, so that the control rod 91 counterclockwise rotates, so that the position of the blocking part 93 moves downward, so that the blocking part 93 cannot block the communication hole 71 any more, at this time, the water in the water box 8 can enter the water storage cavity 1 through the communication hole 71.

[0075] As can be seen, by using the above-mentioned control structure 9, once the water in the water storage cavity 1 is lower than the preset height, the communication hole 71 is opened, so that the water in the water box 8 can enter the water storage cavity 1, and before the water in the water box 8 completely flows into the water storage cavity 1, the water level in the water storage cavity 1 can be maintained at the preset height.

[0076] In other embodiments, the control rod 91 can also be slidingly connected to the shell 7 in the up-down direction, when the water level in the water storage cavity 1 changes, the float part 92 moves up and down accordingly and drives the blocking part 93 to move up and down, so that the blocking part 93 can block and open the communication hole 71.

[0077] In the above embodiment, the second ionization assembly is located outside the water storage cavity 1, and the water in the water storage cavity 1 is atomized into water mist by the atomizing member 3 after being ionized by the first ionization assembly 2, and then the second ionization assembly 4 ionizes the water mist again, so as to ensure the content of the strong oxidizing particles in the water mist, and finally the water mist is discharged from the outlet 432 of the second ionization assembly to the intermediate chamber 30.

[0078] As shown in Figures 8-12 The second embodiment of the utility model is shown, in the embodiment, the sterilization module 10 includes the water storage cavity 1, the first ionization assembly 2 at least partially located in the water storage cavity 1, the first ionization assembly 2 is used to ionize the water in the water storage cavity 1, the sterilization module 10 also includes the second ionization assembly 4 and the atomizing member 3, the second ionization assembly 4 is at least partially located in the water storage cavity 1 to be used to ionize the water in the water storage cavity 1 again, and the atomizing member 3 is used to atomize the water after being ionized by the second ionization assembly 4 into water mist.

[0079] The difference between the embodiment and the above embodiment is that, in the embodiment, at least part of the second ionization assembly is located in the water storage cavity 1, and the water in the water storage cavity 1 is ionized by the second ionization assembly 4 again after being ionized by the first ionization assembly 2, and then the atomizing member 3 atomizes the water after being ionized by the second ionization assembly 4 into water mist. After being ionized twice, the water in the water storage cavity 1 has enough strong oxidizing particles, and the water mist atomized by the atomizing member 3 also has enough strong oxidizing particles in the particles, which can kill bacteria and viruses in the intermediate chamber 30 when the water mist drifts to all parts of the intermediate chamber 30.

[0080] In the embodiment, the first ionization assembly 2 is used to ionize the water in the water storage cavity 1 into at least hydroxyl ions, the second ionization assembly 4 is also used to ionize the water in the water storage cavity 1 into at least hydroxyl ions, the atomizing member 3 is located at the outlet 432 of the ionization cavity 43, and other structures of the embodiment can refer to the first embodiment, which will not be repeated here.

[0081] The sterilization module 10 is located in the refrigeration chamber 31, in order to avoid that the water mist emitted by the sterilization module 10 forms too much condensed water in the refrigeration chamber 31, the utility model also provides a control method of the refrigeration equipment 100, which comprises the following steps: after the sterilization module 10 works once, when the time accumulated after the door body 50 is opened reaches a preset value, the sterilization module 10 works again.

[0082] In the above steps, when the sterilization module 10 works once, the concentration of bacteria in the refrigeration compartment 31 can reach the safe range, and then the sterilization module 10 stops working. During the use of the refrigeration equipment 100, the cumulative time of the door body 50 being opened reaches a preset value, which means that new food is put into the refrigeration compartment 31 and bacteria in the external air enter the refrigeration compartment 31. At this time, the sterilization module 10 can be started again to make the concentration of bacteria in the refrigeration compartment 31 reach the safe range.

[0083] It should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the present specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.

[0084] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
