Description

Technical Field

[0001] The invention relates to the technical field of refrigerator sterilization, and in particular to an ion sterilization refrigerator. Background Art

[0002] The sterilization technologies in refrigerators mainly include ions, photocatalysis, chlorine dioxide, deep ultraviolet and ozone. From the perspective of effectiveness, the above technologies themselves or the technical application solutions have major defects. Ions mostly kill bacteria in the air through their own electrical properties, but the sterilization effect on the surface of objects is poor. Ozone and chlorine dioxide mainly kill bacteria through oxidizing components (but their oxidizing properties will cause accelerated aging of materials. Photocatalysis produces free radicals and uses free radicals to achieve sterilization in a small range (the half-life of free radicals is extremely short). Deep ultraviolet (UVC) has a short wavelength and poor penetration effect, which leads to the technology being mostly used in a smaller range.

BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to more clearly illustrate the technical solution of the present application, the drawings required for use in the embodiments are briefly introduced below. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0047] Figure 1 This is a schematic diagram of an ion sterilization refrigerator according to the present application. DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Ion sterilization technology: Its core is to use the charge of ions (especially negative ions) to attract and neutralize bacteria, viruses and other microorganisms in the air through electrostatic effects, thereby achieving a sterilization effect. Although ion technology performs well in the air and can effectively reduce the number of suspended microorganisms, its direct sterilization ability on the inner wall of the refrigerator and the surface of stored food is relatively weak. In addition, the rapid sedimentation of ions is also one of the key factors restricting its widespread application. Although negative ions have certain benefits to human health, such as improving air quality and promoting metabolism, if their sedimentation rate cannot be effectively controlled, it will be difficult to achieve a full-scale and lasting sterilization effect on the inside of the refrigerator. Therefore, the development of efficient and stable ion sedimentation technology has become the key to improving the application effect of ion sterilization technology in refrigerators.

[0050] Ozone and chlorine dioxide sterilization technology: Both methods rely on their strong oxidizing properties to destroy the cell structure of bacteria, thereby achieving efficient sterilization. However, it is precisely this strong oxidizing property that makes them easily cause accelerated aging of materials when they come into contact with the internal materials of the refrigerator, including discoloration of plastic parts and corrosion of metal parts, affecting the service life and overall performance of the refrigerator. Therefore, when using such technologies, the concentration and release method of ozone or chlorine dioxide must be strictly controlled to reduce damage to the materials.

[0051] Photocatalytic sterilization technology: This technology uses a specific light source to excite a catalyst (such as titanium dioxide) to produce highly oxidizing free radicals, which can quickly come into contact with bacteria in a small range and destroy their structure. However, the half-life of free radicals is extremely short, which limits the expansion of its sterilization range. At the same time, the photocatalytic efficiency is affected by many factors such as the intensity of the light source, the uniformity of the catalyst distribution, and the reaction environment, which limits the application effect of this technology in closed spaces such as refrigerators with limited light conditions.

[0052] Deep ultraviolet (UVC) sterilization technology: UVC light has a short wavelength and high energy, which can directly destroy the DNA or RNA of bacteria, thereby achieving rapid sterilization. However, UVC light has very poor penetration and cannot penetrate most solid materials. Therefore, it is mostly used in the air circulation system inside the refrigerator to sterilize the circulating air, while it is difficult to reach the dead corners inside the refrigerator and the gaps between densely stored food. In addition, UVC light is harmful to the human body, and it is necessary to ensure that it will not leak to the outside of the refrigerator during use.

[0053] However, except for the ion sterilization technology, the above sterilization technologies will affect the internal materials of the refrigerator, and the ion sterilization technology cannot effectively sterilize the surface of objects. Based on this, the present application provides the following embodiments.

[0054] Figure 1 This is a schematic diagram of an ion sterilization refrigerator according to the present application.

[0055] See also Figure 1 It can be seen that this embodiment provides an ion sterilization refrigerator, the refrigerator comprising:

[0056] The box body 100 has a reserved space inside. Specifically, in this embodiment, the box body 100 is used to support the refrigerator body.

[0057] The refrigerator further comprises:

[0058] The door body 200 is pivotally connected to one side of the box body 100. Specifically, in this embodiment, the door body 200 is used to open and close the refrigerator.

[0059] The refrigerator further comprises:

[0060] The sterilization function room 300 is arranged in the reserved space of the box body 100. Specifically, in the present embodiment, the sterilization function room 300 is the core area to be sterilized in the present embodiment, wherein the sterilization function room 300 can be a refrigerator, a freezer or a specific function room.

[0061] It should be noted that the ion generating component 400 may be installed in any position including the housing 100 , the inner side of the door 200 , the inner space of the sterilization function room 300 , or the air duct component 500 , that is, the ion generating component 400 may be installed in any position that can sterilize the sterilization function room 300 .

[0062] Among them, the ion generating component 400 is also configured to intermittently generate the negative ions when the refrigerator is not performing the defrost program. Specifically, in this embodiment, the ion generating component 400 does not generate negative ions continuously, but generates negative ions at regular intervals when the refrigerator is not performing the defrost program.

[0063] The refrigerator further comprises:

[0064] The ion generating component 400 is configured to generate negative ions when the refrigerator is not performing a defrost procedure. Specifically, in this embodiment, negative ions for sterilization are generated by the ion generating component 400, and the working time of the ion generating component 400 needs to be separated from the time interval of the defrost procedure of the refrigerator.

[0065] The refrigerator further comprises:

[0066] An air duct component 500, wherein the air duct component 500 and the sterilization function compartment 300 form a ventilation circuit, and the air duct component 500 is configured to determine whether to open or close the ventilation circuit between the air duct component 500 and the sterilization function compartment 300 according to the sterilization condition of the sterilization function compartment 300 by the ion generating component 400; when the ventilation circuit is closed, the negative ions generated by the ion generating component 400 are deposited on the inner surface of the sterilization function compartment 300;

[0067] The preparation material of the refrigerator includes antibacterial components, including but not limited to copper ion antibacterial agents, silver ion antibacterial agents, and zinc ion antibacterial agents.

[0068] Specifically, in this embodiment, by opening or closing the ventilation circuit of the air duct component 500, the precipitation of negative ions and the refrigeration of the refrigerator are achieved, and the interior of the sterilization function chamber 300 and the surfaces of objects stored in the sterilization function chamber 300 are effectively sterilized through the precipitation of negative ions.

[0069] It should be noted that in order to avoid the problem of poor ion precipitation effect in parts such as the inner tank of the refrigerator, this embodiment adds antibacterial components to the preparation materials of this type of components, and further enhances the sterilization effect through the antibacterial components.

[0070] Furthermore, in some embodiments, the refrigerator further comprises:

[0071] A refrigeration assembly 600, wherein the refrigeration assembly 600 is configured to provide low-temperature air for the sterilization function room 300;

[0073] The air duct assembly 500 is also configured as:

[0075] Specifically, in this embodiment, the refrigeration component 600 is a conventional component in a refrigerator, and the refrigeration component 600 provides low-temperature air to the inside of the refrigerator to achieve a refrigeration effect; the temperature sensor 700 is used to obtain the real-time temperature inside the sterilization function chamber 300.

[0076] The opening and closing of the air duct component 500 is determined by the real-time temperature inside the sterilization function chamber 300. It can be understood that the negative ions are precipitated by the cooperation of the ion generating component 400 and the switch of the air duct component 500.

[0077] Furthermore, in some embodiments, the refrigeration assembly 600 is further configured as:

[0078] Record the duration of providing low-temperature air to the sterilization function room 300;

[0079] The air duct assembly 500 is also configured as:

[0080] Whether to open or close the ventilation circuit between the sterilization function chamber 300 is determined according to the duration.

[0081] Specifically, in this embodiment, unlike the above-mentioned method of controlling the precipitation of intern anions by the real-time temperature inside the sterilization function room 300, this embodiment also introduces the method of controlling the precipitation of anions by using the duration of providing low-temperature air to the sterilization function room 300.

[0082] It should be noted that in order to avoid the problem of control confusion, the negative ion precipitation controlled by the real-time temperature inside the sterilization function chamber 300 and the negative ion precipitation controlled by the duration of providing low-temperature air cannot be operated at the same time, that is, only the real-time temperature or the duration can be used to control the negative ion precipitation at the same time.

[0083] Furthermore, in some embodiments, the refrigerator further comprises:

[0084] The controller 800 is disposed at the top of the box 100; the controller 800 is configured as follows:

[0085] When the refrigerator is not in the defrosting process, obtaining the real-time temperature and the duration;

[0086] An air duct control instruction is generated according to the duration or the real-time temperature; the air duct control instruction is used to open or close the ventilation circuit between the air duct component 500 and the sterilization function chamber 300.

[0087] Specifically, in the present embodiment, the opening and closing of the air duct assembly 500 is controlled by the controller 800 , and the opening and closing of the air duct assembly 500 is controlled by the relevant air duct control instructions generated by the controller 800 .

[0088] Among them, since the controller 800 needs to generate the air duct control instruction through the duration or the real-time temperature, the controller 800 needs to be communicatively connected or electrically connected to the temperature sensor 700 and the air duct assembly 500 respectively.

[0089] Furthermore, in some embodiments, the air duct assembly 500 includes:

[0090] A functional compartment air duct 510, wherein the functional compartment air duct 510 is arranged on a side of the sterilization functional compartment 300 away from the door body 200;

[0092] The return air port 530 is arranged at the bottom of the sterilization functional room 300 away from the door body 200, and the return air port 530 is connected to the functional room air duct 510 and the sterilization functional room 300 respectively;

[0093] An electric damper 540, wherein the electric damper 540 is disposed on the return air port 530; the electric damper 540 is configured to be opened and closed according to the air duct control instruction;

[0094] The functional room air duct 510, the air inlet 520, the air return port 530 and the sterilization functional room 300 form a ventilation circuit.

[0095] Specifically, in the present embodiment, the main structural components of the air duct assembly 500 include the functional compartment air duct 510, the air inlet 520 and the return air outlet 530, wherein the functional compartment air duct 510, the air inlet 520 and the return air outlet 530 are all conventional air duct components, and the electric damper 540 in the air duct assembly 500 is the core control component of the air duct assembly 500 in the present embodiment; the controller 800 issues relevant air duct control instructions to control the opening and closing of the electric damper 540, so as to realize the precipitation of negative ions inside the sterilization functional compartment 300 and the air circulation and refrigeration inside the sterilization functional compartment 300.

[0096] The specific process of the controller 800 controlling the electric damper 540 includes the following two implementation modes:

[0097] The first implementation method:

[0098] When the refrigerator is not in the defrosting process, determining whether the duration is greater than a first threshold;

[0099] When the duration is less than the first threshold, a first air duct control instruction is generated, where the first air duct control instruction is used to close the electric damper 540;

[0100] When the duration is not greater than the first threshold, a second air duct control instruction is generated, where the second air duct control instruction is used to open the electric damper 540 .

[0101] The second implementation method:

[0102] When the refrigerator is not in the defrosting process, determining whether the real-time temperature is lower than a second threshold;

[0103] When the real-time temperature is lower than the second threshold, a third air duct control instruction is generated, and the third air duct control instruction is used to open the electric air door 540;

[0107] Specifically, in this embodiment, the variable frequency fan 550 serves to deliver wind to the sterilization function room 300. The variable frequency fan 550 can not only speed up the cooling of the sterilization function room 300, but also improve the efficiency of removing bacteria after sterilization in the sterilization function room 300.

[0108] This embodiment has the following advantages:

[0109] By utilizing the effect of negative ion bacterial sedimentation, through antibacterial treatment of the material surface, and combining the design of ion generator control rules, the sterilization function of the refrigerator can be realized to solve the current pain points in the industry.
