Detailed Description

Referring to fig. 1 to 3, fig. 1 is a schematic view of a refrigerator 1 according to an embodiment of the present invention, fig. 2 is a sectional view of the refrigerator 1 according to an embodiment of the present invention, and fig. 3 is a rear view of a cabinet 20 in the refrigerator 1 according to an embodiment of the present invention, which conceals a housing 28 and an insulation layer 26. The present invention provides a refrigerator 1, and the refrigerator 1 may generally include a cabinet 20 and a door 30.

The cabinet 20 may include an outer shell 28 and one or more inner liners 22, the outer shell 28 being located at the outermost side of the overall refrigerator 1 to protect the overall refrigerator 1. The space between the liner 22 and the outer shell 28 is filled with a thermal insulation material (forming a foam layer 26) to reduce the heat dissipation of the liner 22. Each liner 22 may define one or more storage compartments 24, and the storage compartments 24 may be configured as a refrigerator compartment, freezer compartment, temperature change compartment, or the like. For example, as shown in fig. 1 to 3, the number of the liners 22 may be two, and the storage compartments 24 of the two liners 22 may be configured as a refrigerating compartment and a freezing compartment, respectively. Of course, those skilled in the art will recognize that the number, function and arrangement of the specific storage compartments 24 may be configured according to the requirement in advance, which will not be described herein.

The door body 30 may be disposed at the front of the box body 20 for opening and closing the storage compartments 24, the door body 30 may be disposed at one side of the box body 20 in a hinged manner, and the storage compartments 24 may be opened and closed in a pivoting manner, and the number of the door bodies 30 may be matched with the number of the storage compartments 24, so that the storage compartments 24 may be opened individually one by one.

Further, the refrigerator 1 may further include a refrigeration system operable to provide cooling to each storage compartment 24. Specifically, the refrigeration system may include a compressor 60, a condenser (not shown), and an evaporator 70 connected in series in a refrigerant circuit.

The compressor 60 is used as a power of the refrigerating system, a compressor compartment is provided at the bottom of the rear side of the case 20, and the compressor 60 may be provided in the compressor compartment. The compressor 60 increases the pressure and temperature of the refrigerant vapor by compression, creating a condition for transferring heat of the refrigerant vapor to an external environment medium, i.e., compressing the low-temperature low-pressure refrigerant vapor to a high-temperature high-pressure state so that the refrigerant vapor can be condensed using normal-temperature air or water as a cooling medium.

The condenser may also be disposed in the compressor compartment, and is a heat exchange device that uses the environment to remove heat from the high-temperature and high-pressure refrigerant vapor from the compressor 60, thereby cooling and condensing the high-temperature and high-pressure refrigerant vapor into a refrigerant liquid at a high pressure and a normal temperature.

An evaporator 70 may be provided in the cabinet 20 to supply cold to the storage compartment 24 of the refrigerator 1. The case 20 may be provided therein with an evaporator chamber 29, the evaporator chamber 29 being in communication with each storage compartment 24 through a wind path system, and an evaporator 70 being provided in the evaporator chamber 29.

It should be noted that the above is only one arrangement mode of each component of the refrigeration system in the refrigerator 1 of the present embodiment, and those skilled in the art may obtain other arrangement modes in the prior art, for example, the compressor 60 and the condenser are arranged on the top of the box 20, which is not described herein.

Further, the refrigerator 1 may further include a blower fan 50, and the blower fan 50 may be disposed adjacent to the evaporator 70 to promote a flow of cooling air that exchanges heat with the evaporator 70 of the cooling system and circulates through each storage compartment 24. Typically, the blower 50 is also configured to be activated when the refrigeration system is running (compressor 60 is running) and deactivated when the refrigeration system is deactivated (compressor 60 is deactivated).

Referring to fig. 4 to 6, fig. 4 is a schematic view of a sterilizing and deodorizing device 10 in a refrigerator 1 according to one embodiment of the present invention, fig. 5 is a sectional view of the sterilizing and deodorizing device 10 in the refrigerator 1 according to one embodiment of the present invention, and fig. 6 is a schematic view of the sterilizing and deodorizing device 10 in the refrigerator 1 according to one embodiment of the present invention.

In some embodiments, the refrigerator 1 may further include a sterilization and deodorization device 10, where the sterilization and deodorization device 10 may be disposed in the storage compartment 24 and can release ion wind for sterilization and deodorization to the storage compartment 24, so as to effectively eliminate bacteria and odor, ensure food safety of users, and effectively improve use experience of users.

Specifically, the sterilization and deodorization device 10 may further include a housing 100 and an electrode set 200. The housing 100 defines a cavity therein, and the housing 100 further has a plurality of air inlets 124c and a plurality of air outlets 112a for communicating the cavity with an external environment (when the sterilizing and deodorizing device 10 is disposed in the storage compartment 24, the external environment is the storage compartment 24), and air in the storage compartment 24 can enter the cavity through the plurality of air inlets 124c and be re-discharged into the storage compartment 24 through the plurality of air outlets 112 a. The electrode assembly 200 is disposed in the cavity, and may include at least one excitation electrode 210 and a receiving electrode 220, wherein the receiving electrode 220 is disposed on a side close to the exhaust ports 112a, and the excitation electrode 210 is disposed on a side of the receiving electrode 220 away from the exhaust ports 112 a.

The location of the sterilizing and deodorizing device 10 can be flexibly selected. For example, the sterilization and odor removal device 10 may be disposed at a top wall, side wall, bottom wall, etc. of the storage compartment 24. While the sterilizing and deodorizing device 10 may be provided at the top wall of the storage compartment 24, the air outlet 112a may be provided downward so as to discharge the ion wind downward.

The sterilization and deodorization apparatus 10 may further include a control circuit (not shown) that generates a potential difference between the excitation electrode 210 and the receiving electrode 220, and generates ion wind that promotes collisions with air molecules entering the cavity and is discharged from the plurality of air outlets by using the potential difference.

The corona discharge may be classified into a positive polarity and a negative polarity according to the polarity of the power supply voltage used. The direction of the ion wind is directed from the high voltage electrode to the low electrode, whether positive or negative. The excitation electrode 210 in this embodiment may be a high voltage electrode and the receiving electrode 220 may be a low electrode. That is, the ion wind is blown toward the receiving electrode 220 by the excitation electrode 210.

Referring to fig. 6, the arrow direction in fig. 6 refers to the flow direction of air, circles represent electrons, squares represent suspended organisms, triangles represent odor molecules, and ellipses represent air molecules. The following describes a specific process of implementing the sterilization and deodorization function of the sterilization and deodorization device 10: air in the storage compartment 24 can enter the cavity through the plurality of air inlets 124c, the tips of the excitation electrodes 210 ionize to generate high-energy electrons, and the electrons directionally move under the action of an electric field and collide with air molecules, so that the air molecules move to generate ion wind blowing to one side of the receiving electrode 220. The electrons break up the odor molecules while moving directionally, exciting oxygen to generate ozone, and the high voltage ionization of the exciting electrode 210 breaks down the cells of the suspended organisms for sterilization.

In addition, since the ionized electrons move directionally in the electric field at a high speed, the electrons can transfer their own momentum to gas molecules in the air to form mild (low wind speed) ion wind, so that sterilization and deodorization of the storage compartment 24 are realized, and the sterilization and deodorization device 10 does not need to be provided with an additional mechanical fan to promote ion wind diffusion.

In some embodiments, the receiving electrode 220 may also have a mesh shape (not shown) so as to allow the air after sterilization and deodorization to pass therethrough, thereby facilitating the discharge from the air outlet 112 a. Since oxygen in the air may be oxidized to ozone during the spot-putting process, a large amount of ozone may cause discomfort to the user, a catalytic layer (not shown) may be further provided on (or near) the receiving electrode 220. The catalytic layer has catalytic activity, and contacts the catalytic layer after the ion wind passes through the receiving electrode 220, and a large amount of ozone and a small amount of odor molecules are eliminated by catalytic reaction under the catalysis of the catalytic layer, so that ozone poisoning caused by excessive ozone discharged into the external environment is prevented. In addition, the catalytic layer can also retain a small amount of ozone in eliminating a large amount of ozone, so that the sterilization and deodorization effects of the storage compartment 24 can be further improved by using a small amount of ozone.

In some embodiments, the refrigerator 1 may further include an odor sensor 40, where the odor sensor 40 is configured to detect an odor concentration of the storage compartment 24, so that the refrigerator 1 starts and stops the sterilization and deodorization device 10 according to an odor value.

Specifically, the odor sensor 40 allows one to detect the odor concentration of the odor molecules in the air. For example, the odor concentration of hydrogen sulfide methyl amine and the like emitted by spoilage and decay during the food storage process in the storage space can be detected, and the odor concentration of hydrogen sulfide methyl amine is used as the reference quantity of the start-stop sterilization and deodorization device 10, so that the odor concentration of hydrogen sulfide methyl amine can be controlled in a targeted manner, the odor concentration of the storage compartment 24 is controlled within a reasonable range, and the air in the storage compartment 24 is ensured to be kept fresh all the time.

It should be noted that the odor sensor 40 is capable of detecting odor molecules, and is not limited to hydrogen sulfide methyl amine, and those skilled in the art can flexibly configure the detection range of the odor sensor 40 to adapt to different storage environments.

In some further embodiments, the sterilization and odor removal device 10 is activated when a continuous period of time when the odor concentration is detected to exceed the first contamination threshold value is longer than a first preset period of time. The sterilization and odor removal device 10 is deactivated when a continuous period of time having an odor concentration below a freshness threshold value is detected that is greater than a second preset period of time, wherein the first pollution threshold value is configured to be greater than the freshness threshold value.

In this embodiment, the condition triggering actuation of the sterilization and odor removal device 10 is not simply exceeding the first contamination threshold, but rather the continuous time period exceeding the first contamination threshold is greater than a first predetermined time period, and the condition triggering deactivation of the sterilization and odor removal device 10 is not simply exceeding the freshness threshold, but rather the continuous time period exceeding the freshness threshold is greater than a second predetermined time period.

The inventors realized that: when the odor concentration of hydrogen sulfide methyl amine reaches 0.05ppm, the user may smell the smell of the rotten eggs, and when the odor concentration of hydrogen sulfide methyl amine is less than 0.01ppm, the air in the storage compartment 24 may be considered to be fresh. It can be seen that the difference between the two is small and that small changes in the odor concentration of the odor molecules can exceed the first contamination threshold or fall below the freshness threshold.

Therefore, if simply set to exceed the first contamination threshold, the sterilization and deodorization device 10 is started, and the sterilization and deodorization device 10 is stopped below the freshness threshold, this not only results in frequent start-up and stop of the sterilization and deodorization device 10, waste of electric power, influence on the service life thereof, but also increases the probability of starting or stopping the sterilization and deodorization device 10 due to sporadic fluctuation of the odor concentration touching the first contamination threshold or freshness threshold. The start-up and shutdown conditions of the present embodiment can effectively avoid the occurrence of the above-mentioned situations, and improve the reliability of the sterilization and deodorization device 10.

Further, the refrigerator 1 may further include a humidity sensor disposed in the storage compartment 24 to detect the air humidity of the storage compartment 24. When the continuous time period when the odor concentration exceeds the second pollution threshold value is detected to be longer than the first preset time period, and the air humidity of the storage compartment 24 reaches the preset humidity, the sterilization and deodorization device 10 is started. The second contamination threshold is configured to be less than the first contamination threshold and greater than the freshness threshold.

The inventors have also appreciated that the sterilizing and deodorizing device 10 works better in a range of humidity. Since the sterilizing and deodorizing device 10 ionizes air molecules, odor molecules, etc. in a high-voltage discharge manner during operation, and the humidity reaches a certain level during the discharge process of the sterilizing and deodorizing device 10, the water molecules in the air can participate in the ionization process and generate a certain amount of water ions (water ions or atomic groups lose or get one or more electrons to form charged particles), and the water ions can strongly wrap dust and mold, inhibit the growth of mold, and further improve the sterilizing and deodorizing effect of the sterilizing and deodorizing device 10.

In this embodiment, the condition for triggering the sterilization and deodorization apparatus 10 to start may be that the continuous time period when the odor concentration exceeds the second pollution threshold is longer than the first preset time period, and the air humidity of the storage compartment 24 reaches the preset humidity. That is, the starting condition properly reduces the requirement for the concentration of the odor, if the air humidity reaches the preset humidity, the sterilizing and deodorizing effect of the sterilizing and deodorizing device 10 is considered to be better, the sterilizing and deodorizing device 10 can be started in advance, the improving effect of the air humidity on the sterilizing and deodorizing effect is fully utilized, and the sterilizing and deodorizing effect is improved.

In some embodiments, the second contamination threshold is configured to be any multiple between 0.7 and 0.95 times the first contamination threshold, e.g., 0.7 times, 0.8 times, 0.95 times, etc. By the above definition it is ensured that the second contamination threshold is not too small, i.e. that the aim of activating the sterilization and odour removal device 10 is to reduce the odour concentration.

In some embodiments, when the sterilization and deodorization apparatus 10 is in an operation state and the air blower 50 is stopped with the cooling system stopped, the air blower 50 is controlled to be started again. That is, when the refrigeration system is not refrigerating (may be when the compressor 60 is stopped), the air blower 50 is independently started, so that the air blower 50 can be used to diffuse ion air, and the sterilization and deodorization effects are improved.

Further, in the process that the air supply fan 50 is restarted, the air supply fan 50 can also operate the air supply fan 50 according to the preset time interval and the preset operation duration to prevent the excessive air flow from air drying the food.

Referring to fig. 2 and 3, in some embodiments, each liner 22 has an air supply port 22a and an air return port 22b for circulating a flow of the refrigerant air, and an odor sensor 40 is provided at the air return port 22b to detect an odor concentration of the refrigerant air flowing through the air return port 22 b.

Since the refrigerator 1 supplies air into the storage compartment 24, air is returned from the return air inlet 22b while maintaining the air pressure balance. The odor sensor 40 is disposed at the air return opening 22b, and air flows continuously through the odor sensor 40, so that the odor sensor 40 can detect the overall odor condition of the storage compartment 24, and the detection data has high authenticity and high reliability.

In some embodiments, the sterilizing and deodorizing device 10 may further include an ultraviolet lamp 80, wherein the ultraviolet lamp 80 is disposed in the cavity and configured to emit ultraviolet light when turned on to irradiate ultraviolet light on the catalytic layer to further eliminate ozone blown out of the catalytic layer, and wherein the ultraviolet lamp 80 is configured to be turned on and off in synchronization with the electrode assembly 200.

From the foregoing, it can be seen that certain ozone is generated during operation of the sterilization and deodorization apparatus 10, and the catalytic layer can decompose a large amount of ozone and retain a small amount of ozone. In this embodiment, the ultraviolet light generated by the ultraviolet lamp 80 irradiates the catalytic layer, and ozone can be decomposed substantially entirely. In addition, ultraviolet light generates photoelectric effect on the catalytic honeycomb block, converts light energy into chemical energy, excites surrounding water molecules and oxygen molecules to ionize, blows into the storage compartment 24 and can decompose organic pollutants, and in addition, the ultraviolet light has sterilization effect and can kill microorganisms which are bred in the module due to condensation generated by opening the door of the refrigerator 1.

Further, when the door 30 of the refrigerator 1 is opened, the ultraviolet lamp 80 and the electrode set 200 are simultaneously stopped, and the operation is continued after the door 30 of the refrigerator 1 is closed, so as to avoid the influence of ultraviolet light on the health of the user.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
