Description

Technical Field

[0001] The embodiments of the present application relate to the field of refrigeration technology, and in particular, to a refrigerator. Background Art

[0002] Currently, to meet the user's ice-making needs, a refrigerator is usually equipped with an ice maker for making ice. After the ice maker makes ice, the ice is stored in an ice storage box, and the user can take ice from the ice storage box according to needs.

[0003] In the related art, the ice maker is arranged in the refrigerating compartment of the refrigerator, or the ice maker is arranged on the door of the refrigerator. The user will frequently open the door of the refrigerator. When the user takes ice, the ice storage box will also be opened, which will cause microorganisms to enter the environment where the ice maker is located, and contaminate the ice maker and the ice in the ice storage box.

[0004] A sterilization device is provided to sterilize the ice maker. However, the sterilization effect is not obvious. Therefore, the present application proposes a refrigerator. Summary of the Invention

[0005] The embodiments of the present application provide a refrigerator, which can solve the technical problem of not obvious sterilization effect on the ice maker.

[0006] In a first aspect, the embodiments of the present application provide a refrigerator, including:

[0007] A box body, in which a refrigerating compartment is defined;

[0008] A door, rotatably connected to the box body to open or close the refrigerating compartment;

[0009] An ice maker for making ice, the ice maker is connected to the box body or the door; the ice maker includes:

[0010] A first bracket;

[0011] An ice-making grid, installed on the first bracket;

[0012] An ice storage box, installed on the first bracket, an ice storage cavity for receiving and storing ice is formed in the ice storage box, and the ice storage cavity is located below the ice-making grid to receive the ice that falls off the ice-making grid;

[0013] A sterilization device, connected to the first bracket, the sterilization device includes:

[0014] A sterilization light source for irradiating the ice storage cavity;

[0015] A controller, electrically connected to the sterilization light source, and the controller is configured to:

[0016] After the ice in the ice cube tray is overturned, control the sterilization light source to turn on to sterilize the ice storage cavity and the ice in the ice storage cavity.

[0017] After frequently opening the box door, microorganisms will enter the environment where the ice maker is located, which is likely to cause bacteria to grow at the ice cube tray. Setting the sterilization light source to sterilize the ice storage cavity and the ice in the ice storage cavity after the ice in the ice cube tray is overturned can ensure that each ice cube produced is clean and avoid the bacteria growing at the ice cube tray from contaminating the ice storage cavity and the ice cubes in the ice storage cavity.

[0018] According to an embodiment of the present application, the controller is configured to:

[0019] After the ice in the ice cube tray is overturned, determine whether the ice storage cavity is full of ice;

[0020] When the ice storage cavity is full of ice, control the irradiation intensity of the sterilization light source to be the second intensity;

[0021] When the ice storage cavity is not full of ice, control the irradiation intensity of the sterilization light source to be the third intensity; wherein, the second intensity is greater than the third intensity.

[0022] Setting to determine whether the ice storage cavity is full of ice after the ice in the ice cube tray is overturned can determine the irradiation intensity according to the amount of ice in the ice storage cavity, so that when there is more ice, the irradiation intensity is large enough to sterilize more thoroughly, and when there is relatively less ice, the irradiation intensity is slightly smaller, which can adapt to the amount of ice cubes, save resources while sterilizing thoroughly.

[0023] According to an embodiment of the present application, the controller is configured to:

[0024] When the ice storage cavity is full of ice, control the sterilization light source to work intermittently at the second start-stop ratio;

[0025] When the ice storage cavity is not full of ice, control the sterilization light source to work intermittently at the third start-stop ratio; wherein, the second start-stop ratio is greater than the third start-stop ratio.

[0026] Setting to determine whether the ice storage cavity is full of ice after the ice in the ice cube tray is overturned can determine the start-stop ratio of the sterilization light source according to the amount of ice in the ice storage cavity, so that when there is more ice, the total irradiation time is long enough to sterilize more thoroughly, and when there is relatively less ice, the total irradiation time is relatively short, save resources while sterilizing thoroughly.

[0027] According to an embodiment of the present application, a first opening communicating with the ice storage cavity is formed at the top of the ice storage box; the ice storage box has a closed position and an open position. When the ice storage box is in the closed position, the first opening is in a closed state closed by the first bracket, and when the ice storage box is in the open position, the first opening is in an open state;

[0028] The controller is configured to:

[0029] After receiving the signal that the ice storage box is switched from the open position to the closed position, control the sterilization light source to turn on.

[0030] After the ice storage box is opened, the probability of bacteria entering the ice storage cavity will increase. Setting the controller to perform sterilization after receiving the signal that the ice storage box is switched from the open position to the closed position can eliminate the microorganisms that enter the ice storage cavity after the ice storage box is opened, ensuring that the ice storage cavity remains clean.

[0031] According to an embodiment of the present application, the controller is configured to:

[0032] After receiving the signal that the ice storage box is switched from the open position to the closed position, obtain the height of the ice in the ice storage cavity, control the sterilization light source to work intermittently, and control the start-stop ratio of the intermittent operation of the sterilization light source according to the height of the ice in the ice storage cavity, so as to determine a better start-stop ratio according to the different amounts of ice cubes in the ice storage cavity, saving resources while ensuring the sterilization effect.

[0033] According to an embodiment of the present application, the height of the ice in the ice storage cavity is H, and there are n preset heights in the controller, n≥2, the first preset height is H1, and the nth preset height is H n , from the first preset height H1 to the nth preset height H n gradually increases;

[0034] There are n + 1 preset start-stop ratios in the controller, the first preset start-stop ratio is G1, and the n + 1th preset start-stop ratio is G n+1 , from the first preset start-stop ratio G1 to the n + 1th preset start-stop ratio G n+1 gradually increases;

[0035] When H≤H1, the start-stop ratio of the sterilization light source is G1;

[0036] When H n-1 <H≤H n , the start-stop ratio of the sterilization light source is G n ;

[0037] When H>H n , the start-stop ratio of the sterilization light source is G n+1 .

[0038] Setting multiple height intervals and setting corresponding start-stop ratios for each interval can quickly determine a better start-stop ratio according to the height H of the ice in the ice storage cavity, which is efficient and convenient.

[0039] According to an embodiment of the present application, the controller is configured to:

[0040] After receiving the signal that the ice storage box is switched from the open position to the closed position, control the irradiation intensity of the sterilization light source according to the height of the ice in the ice storage chamber;

[0041] The height of the ice in the ice storage chamber is H, and there are n preset heights in the controller, n≥2, the first preset height is H1, and the nth preset height is H n , from the first preset height H1 to the nth preset height H n Gradually increase;

[0042] There are n + 1 preset irradiation intensities in the controller, the first preset irradiation intensity is I1, and the n + 1th preset irradiation intensity is I n+1 , from the first preset irradiation intensity I1 to the n + 1th preset irradiation intensity I n+1 Gradually increase;

[0043] When H≤H1, the irradiation intensity of the sterilization light source is I1;

[0044] When H n-1 <H≤H n , the irradiation intensity of the sterilization light source is I n ;

[0045] When H>H n , the irradiation intensity of the sterilization light source is I n+1 .

[0046] Controlling the irradiation intensity of the sterilization light source according to the height of the ice in the ice storage chamber can determine a better irradiation intensity according to the different amounts of ice in the ice storage chamber, ensuring thorough sterilization while saving resources. Moreover, by setting multiple height intervals and corresponding irradiation intensities for each interval, it is possible to quickly determine a better irradiation intensity according to the height H of the ice in the ice storage chamber, which is efficient and convenient.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0118] As described in the background art, in the related art, the ice maker is disposed in the refrigerating compartment of the refrigerator, or the ice maker is disposed on the door of the refrigerator. The user frequently opens the door of the refrigerator, and when taking ice, the user also opens the ice storage box, which may cause microorganisms to enter the environment where the ice maker is located, resulting in contamination of the ice maker and the ice in the ice storage box. It is difficult to inhibit the growth and reproduction of microorganisms in the environment relying on low temperature. A sterilization device is provided to sterilize the ice maker. However, the sterilization uniformity of the ice maker and the sterilization uniformity of the ice cubes are limited. It is difficult to sterilize the bottom of the ice storage cavity and the ice cubes at the bottom of the ice storage cavity through the ice cubes, and the inside of the ice cubes cannot be sterilized, resulting in an insignificant sterilization effect.

[0119] In view of the above technical problems, the present application proposes a refrigerator, which includes a box body, a box door, an ice maker, a sterilization device, and a controller. A refrigerating compartment is defined inside the box body. The box door is rotatably connected to the box body to open or close the refrigerating compartment. The ice maker is used for making ice and is connected to the box body or the box door. The ice maker includes a first bracket, an ice mold, and an ice storage box. The ice mold is installed on the first bracket. The ice storage box is installed on the first bracket, and an ice storage cavity for receiving and storing ice is formed inside the ice storage box. The ice storage cavity is located below the ice mold to receive the ice that falls off the ice mold. The sterilization device is connected to the first bracket and includes a sterilization light source. The sterilization light source is used to irradiate the ice storage cavity. The controller is electrically connected to the sterilization light source and is configured to: after the ice mold flips the ice, control the sterilization light source to turn on to sterilize the ice storage cavity and the ice inside the ice storage cavity. After frequently opening the box door, microorganisms will enter the environment where the ice maker is located, which easily leads to the growth of bacteria at the ice mold. By setting the sterilization light source to sterilize the ice storage cavity and the ice inside the ice storage cavity after the ice mold flips the ice, it can ensure that each ice cube produced is clean and avoid the bacteria growing at the ice mold from contaminating the ice storage cavity and the ice inside the ice storage cavity.

[0120] Reference Figure 1 and Figure 2 In an embodiment of the present application, a refrigerator is proposed. The refrigerator may include a box body 1. A refrigerating compartment 11 may be defined inside the box body 1. Among them, there may be multiple refrigerating compartments 11. The refrigerating compartment 11 may be a refrigerating chamber or a freezing chamber.

[0121] The refrigerator may include a box door 2. The box door 2 may be rotatably connected to the box body 1 so that the box door 2 can open or close the refrigerating compartment 11. Among them, the box door 2 and the box body 1 may be hinged so that the box door 2 can rotate relative to the box body 1. Among them, the box door 2 may be a refrigerating door for closing the refrigerating chamber. The box door 2 may also be a freezing door for closing the freezing chamber.

[0122] The bottom end to the top end of the box body 1 may be the height direction of the box body 1. The box body 1 has a width direction, and one side end to the other side end of the box body 1 may be the width direction of the box body 1. The box body 1 has a front-back direction, and the front side to the back side of the box body 1 may be the front-back direction of the box body 1. Among the height direction, width direction, and front-back direction of the box body 1, any two of them are perpendicular to each other.

[0123] The box door 2 may be connected to the front end of the box body 1. The refrigerating chamber and the freezing chamber may be arranged in sequence in the height direction of the box body 1, and the freezing chamber may be located below the refrigerating chamber. The refrigerating chamber and the freezing chamber may also be arranged in sequence in the width direction of the box body 1.

[0124] The refrigerator may include a refrigeration system. The refrigeration system may include a compressor, a condenser, a throttling device, and an evaporator that are connected in a cycle. When the refrigeration system operates, the compressor compresses the refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor, and transports the refrigerant vapor into the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant liquid, and transports it into the throttling device. After the throttling device reduces the pressure of the refrigerant liquid, the high-pressure and low-temperature refrigerant liquid is transformed into low-pressure and low-temperature refrigerant liquid, and is transported to the evaporator. After receiving the low-pressure and low-temperature refrigerant liquid, the evaporator causes it to boil under isobaric conditions, absorb heat and vaporize to form refrigerant vapor, so as to reduce the temperature in the refrigeration compartment 11.

The ice-making grid 32 is rotatably connected to the first bracket 31. When the water in the ice-making grid 32 forms ice cubes, the driving member 33 drives the ice-making grid 32 to rotate, and the ice cubes on the ice-making grid 32 are removed, so that the ice-making grid 32 completes the ice-turning process. Among them, the driving member 33 can be a driving motor. The driving member 33 is connected to one end of the first bracket 31 in the length direction.

[0130] Reference Figure 3 , Figure 5 and Figure 6 , the ice maker 3 includes an ice storage box 34. The ice storage box 34 is installed on the first bracket 31. An ice storage cavity 341 for receiving and storing ice is formed in the ice storage box 34. The ice storage cavity 341 is located below the ice-making grid 32 to receive the ice removed from the ice-making grid 32. A first opening 342 is formed at the top of the ice storage box 34. The first opening 342 communicates with the ice storage cavity 341. The first opening 342 is located below the ice-making grid 32 so that the ice removed from the ice-making grid 32 enters the ice storage cavity 341. The ice storage box 34 can be made of antibacterial material to improve the cleanliness of the ice cubes.

[0131] In some embodiments, reference Figure 7 and Figure 8 , the refrigerator includes a sterilization device 5. The sterilization device 5 is connected to the first bracket 31. The sterilization device 5 is located on one side of the ice-making grid 32 in the length direction. The sterilization device 5 includes a sterilization light source 51. The sterilization light source 51 is configured to irradiate the ice storage cavity 341 to sterilize the ice storage cavity 341 and the ice in the ice storage cavity 341.

[0132] By arranging the sterilization device 5 on one side of the ice-making grid 32 in the length direction, the sterilization light source 51 of the sterilization device 5 irradiates the inside of the ice storage cavity 341, realizing the sterilization of the ice surface, the inside of the ice cubes and the ice storage cavity, which can effectively improve the sterilization uniformity effect of the ice storage cavity and the ice cubes inside, and ensure the cleanliness of the ice storage cavity 341 and the ice cubes.

[0133] The peak wavelength of light refers to a specific wavelength value at which the light source radiates the strongest energy. When the light emitted by the light source contains multiple wavelength components, the wavelength corresponding to the maximum radiation intensity (or power density) in its spectral energy distribution is the peak wavelength.

[0134] The dominant wavelength of light refers to the wavelength of the monochromatic light that is closest in color perception to a certain polychromatic light. It is defined by the psychophysical response of the human eye to color and is used to quantify the wavelength value of the dominant color in the mixed light.

[0135] The peak wavelength of the light emitted by the sterilization light source 51 is A, where 400nm ≤ A and A ≤ 450nm, such that the light emitted by the sterilization light source 51 is short-wave visible light.

[0136] The sterilization principle of short-wave visible light is different from that of ultraviolet light. The sterilization principle of ultraviolet light is: directly irradiating the set microorganisms, resulting in the interruption of DNA replication and transcription of the microorganisms, causing the death of the microorganisms. The sterilization principle of short-wave visible light is: after the porphyrin compounds in the microbial cells are irradiated by light, electronic transitions occur, generating reactive substances such as OH-, hydrogen peroxide, and singlet oxygen, which act on the cell wall and cell membrane, resulting in irreversible oxidative damage to the microorganisms.

[0137] UVC sterilization refers to the process of disinfecting microorganisms using the ultraviolet C band (wavelength range of about 100nm - 280nm). The penetration of UVC into common plastic and glass materials is relatively low, and it must be paired with quartz glass to penetrate the encapsulation cover to achieve the sterilization effect, resulting in a relatively high cost; and direct irradiation of UVC is harmful to food ingredients, materials, and the human body. Compared with ultraviolet light, short-wave visible light has better penetration performance, and the penetration rate for ordinary transparent plastic and glass materials exceeds 90%. It can effectively penetrate the encapsulation cover of the sterilization light source 51 and then irradiate the ice storage chamber 341 and the ice cubes in the ice storage chamber 341 to sterilize the ice storage chamber 341 and the ice cubes in the ice storage chamber 341.

[0138] Short-wave visible light has a certain degree of penetration. Short-wave visible light can penetrate ice cubes with a certain transparency to achieve comprehensive sterilization of the ice cube surface, the interior of the ice cubes, the bottom ice cubes in the ice storage chamber 341, and the bottom of the ice storage chamber 341, improving the cleanliness of the ice cubes, ensuring food safety, and short-wave visible light will not cause deterioration effects on the ice cubes, ice maker, box body, and door body, nor is it harmful to the human body.

[0139] Specifically, the peak wavelength of the sterilization light source 51 is set to: 400nm ≤ A and A ≤ 410nm, so that the sterilization effect of the sterilization light source 51 is good.

[0140] Among them, in the refrigerating chamber and when irradiating for the second sterilization time, the sterilization rates of lights with different peak wavelengths are shown in Table 1, and the second sterilization time is less than the first sterilization time. According to Table 2, among 405nm, 415nm, and 425nm, the larger the peak wavelength, the lower the sterilization rate. To ensure a certain sterilization rate, 400nm ≤ A and A ≤ 410nm are set.

[0141] Table 1

[0142] Peak wavelength Short-wave visible light sterilization rate 405 nm 99.1％ 415 nm 98.1％ 425 nm 97.9％

[0143] Among them, when in the freezer compartment and irradiated for the first sterilization time, the sterilization rates of the short-wave visible light with a peak wavelength of 400 nm - 410 nm on the surface of the ice storage box 34, on the surface of the ice cubes, and on the entire ice cubes are shown in Table 2. Among them, a solution with bacteria can be made into ice cubes, the ice cubes made from the solution with bacteria are irradiated with the sterilization light source 51, and then the ice cubes made from the solution with bacteria are melted to test the sterilization rate of the entire ice cubes.

[0146] In some embodiments, the main wavelength of the light emitted by the sterilization light source 51 is D, 425 nm ≤ D, and D ≤ 435 nm, so that the user can see the sterilization light source 51 emitting light, enabling the user to intuitively feel the sterilization function of the refrigerator and improving the user experience. However, the light with a main wavelength of 425 nm - 435 nm appears purple-blue, and the user's acceptance of purple is relatively low.

[0147] In some embodiments, a phosphor layer is coated on the surface of the sterilization light source 51. The phosphor layer is used to adjust the main wavelength of the light emitted by the sterilization light source 51. The phosphor layer is configured to adjust the main wavelength of the light emitted by the sterilization light source 51 to B, so that the main wavelength of the light emitted by the sterilization light source 51 after passing through the phosphor layer is B, 440 nm ≤ B, and B ≤ 480 nm. The phosphor layer is provided to remove the purple color of the light, with good visualization effect, so that the user's acceptance of the light is good, and the user's satisfaction is improved. Specifically, the sterilization light source 51 can be a sterilization lamp bead. The phosphor layer is coated on the encapsulation cover of the sterilization lamp bead.

[0148] The thickness of the phosphor layer is E, 50 μm ≤ E, and E ≤ 300 μm, which can effectively convert light, avoid the thickness of the phosphor layer being too small to effectively convert light, and avoid the thickness being too large resulting in light loss due to the difficulty of light passing through the phosphor layer, and at the same time avoid the thickness being too large affecting the heat dissipation of the sterilization light source 51.

[0149] The concentration of the phosphor in the phosphor layer is F, 0.1 g / cm 3 ≤ F, and F ≤ 0.6 g / cm 3 , if the concentration of the phosphor in the phosphor layer is too low, the light conversion efficiency will become low. When the concentration of the phosphor in the phosphor layer is appropriately increased, the wavelength stability and conversion efficiency will be improved. However, when the concentration of the phosphor in the phosphor layer is too large, the luminous efficiency will decrease and the color will shift. Set 0.1 g / cm 3 ≤ F, and F ≤ 0.6 g / cm 3, it will improve the wavelength stability and conversion efficiency.

[0150] The phosphor in the phosphor layer can be one or more of strontium chloro-phosphate blue phosphor, barium magnesium aluminate europium blue phosphor, quantum dot blue phosphor, and nitride blue phosphor. The phosphor layer can be one layer or multiple layers.

[0151] In some embodiments, referring to Figure 13 , the sterilization device 5 includes a dimming light source 52. The dimming light source 52 is used to emit light with a main wavelength of C. Specifically, the main wavelength of the light emitted by the dimming light source 52 is C, 445nm ≤ C, and C ≤ 485nm. The light emitted by the dimming light source 52 is mixed with the light emitted by the sterilization light source 51 to form mixed light with a main wavelength of B, 440nm ≤ B, and B ≤ 480nm. When the sterilization light source 51 is started, the dimming light source 52 can be started simultaneously. By mixing with the light emitted by the sterilization light source 51, it can cover the light emitted by the sterilization light source 51, making the purple color invisible to the user, with good visualization effect, good acceptability of the light by the user, and improved user satisfaction.

[0152] There is at least one sterilization light source 51 and at least one dimming light source 52. The number of dimming light sources 52 does not exceed the number of sterilization light sources 51, which can better adjust the color of the light while saving costs. The dimming light source 52 and the sterilization light source 51 are arranged at intervals in the length direction of the ice-making grid 32.

[0153] In some embodiments, referring to Figure 8 and Figure 9 , the sterilization device 5 may include a lamp board 53. Among them, the lamp board 53 is used to support the sterilization light source 51. The sterilization light source 51 can be installed on the lamp board 53. The dimming light source 52 can be installed on the lamp board 53.

[0154] Referring to Figure 8 and Figure 9 , one end of the lamp board 53 close to the ice-making grid 32 can be the first end 531 of the lamp board. One end of the lamp board 53 far from the ice-making grid 32 can be the second end 532 of the lamp board. Along the height direction of the box body 1, the second end 532 of the lamp board is lower than the first end 531 of the lamp board, so that the sterilization light source can irradiate towards the ice storage cavity to sterilize the ice storage cavity and the ice cubes in the ice storage cavity. The sterilization light source 51 is installed on the lamp board 53, and the sterilization light source 51 is located on the side of the lamp board 53 facing the ice storage box 34. The lamp board 53 can be a printed circuit board.

[0155] Among them, the first end 531 and the second end 532 of the lamp board can be the two ends in the width direction of the lamp board 53. The length direction of the lamp board 53 can be parallel to the length direction of the ice-making grid 32.

[0157] Reference Figure 11 , an installation cavity 542 is formed inside the lamp cover 54. An installation cavity opening 543 is formed at the top of the lamp cover 54. The installation cavity opening 543 communicates with the installation cavity 542. The lamp board 53 passes through the installation cavity opening 543 and is arranged inside the installation cavity 542. The lamp board 53 is detachably connected to the lamp cover 54, which facilitates the installation and disassembly of the lamp board.

[0158] Reference Figure 11 and Figure 14 , the lamp cover 54 includes a first support portion 545, and the first support portion 545 is located inside the installation cavity 542. A first support surface 5451 is provided on the first support portion 545.

The lamp board 53 is arranged on the first support surface 5451, and the lamp board 53 is stuck below the third snap portion 544, so that the lamp board 53 and the lamp cover 54 are snap-connected. A first limiting surface 5452 is provided on the first support portion 545, and the first limiting surface 5452 is located on one side in the length direction of the lamp board 53 to limit the lamp board.

[0159] Reference Figure 12 、 Figure 13 and Figure 14 , the lamp cover 54 includes a first positioning portion 546. A second positioning portion 533 is formed on the lamp board 53. Among the first positioning portion 546 and the second positioning portion 533, one is inserted into the other to position the lamp board 53 when installing the lamp board 53, which facilitates the installation of the lamp board and prevents the lamp board 53 from being installed in the wrong direction. Among the first positioning portion 546 and the second positioning portion 533, one is a plate body and the other is a groove body, and the plate body is inserted into the groove body.

[0160] In some embodiments, reference Figure 14 and Figure 15 , the lamp cover 54 includes a lamp cover bottom plate 547 at the bottom end of the lamp cover 54. One end of the lamp cover bottom plate 547 close to the ice making grid 32 is the first end 5471 of the bottom plate, and the end of the lamp cover bottom plate 547 far from the ice making grid 32 is the second end 5472 of the bottom plate. Along the height direction of the box body 1, the second end 5472 of the bottom plate is lower than the first end 5471 of the bottom plate, so that the inclination direction of the lamp cover bottom plate is the same as that of the lamp board 53, and the lamp cover bottom plate is adapted to the lamp board 53.

[0161] In some embodiments, with reference to Figure 9 and Figure 10 , the sterilization device 5 may include a power cord 55. One end of the power cord 55 is connected to the lamp board 53, and the other end of the power cord 55 is connected to the controller, enabling power supply to the lamp board 53.

[0162] In some embodiments, the sterilization light source 51 may be a sterilization lamp bead. The optical axis of the sterilization lamp bead refers to the axis of symmetry of the light propagation path. The optical axis of the sterilization lamp bead usually coincides with the vertical direction of the light emitting surface of the sterilization lamp bead chip. The maximum angle between the light emitted by the sterilization light source 51 and the optical axis is the first angle α, 15° ≤ α, and α ≤ 60°. The irradiation intensity of the sterilization light source 51 is I. Among them, 0.001 mW / cm 2 ≤ I, and I ≤ 10 mW / cm 2 , the irradiation intensity of the sterilization light source 51 refers to the luminous flux intensity emitted by the light source in a given direction, usually expressed by the luminous flux received per unit area.

[0163] In some embodiments, with reference to Figure 12 , there are at least two sterilization light sources 51, and the at least two sterilization light sources 51 are arranged at intervals in sequence along the length direction of the ice making grid 32. The distance between the two sterilization light sources 51 with the largest distance is M, M ≥ 2 cm, so that the ice cubes in the ice storage cavity are more evenly sterilized in the length direction of the ice making grid.

[0164] In some embodiments, with reference to Figure 5 , Figure 6 and Figure 15 , the ice maker 3 includes a second bracket 35. The second bracket 35 is detachably connected to the first bracket 31. The ice making grid 32 is installed on the second bracket 35, and the ice making grid 32 is rotatably connected to the second bracket 35.

[0165] A first installation space 313 is formed on the first bracket 31, and a first installation opening 314 is formed on the first bracket 31.

[0166] The second bracket 35 passes through the first installation opening 314 and is inserted into the first installation space 313. The second bracket 35 is connected to the first bracket 31 in a limiting manner. The driving member 33 is connected to the ice making grid 32, so that the second bracket 35 is fixed on the first bracket 31, and the driving member 33 can drive the ice making grid 32 to rotate. When the second bracket 35 is separated from the first bracket 31, the driving member 33 is separated from the ice making grid 32.

[0167] In some embodiments, the ice storage box 34 has a closed position. When the ice storage box 34 is in the closed position, the first opening 342 is in a closed state closed by the first bracket 31. The ice storage box 34 has an open position.

A third support surface 31721 is provided on the second mounting plate 3172. The ice storage box 34 includes a first sliding portion 343. The ice storage box 34 includes a second sliding portion 344.

[0177] In some embodiments, refer to Figure 4, an air guiding channel 318 is formed on the first bracket 31. The air guiding channel 318 is arranged along the length direction of the first bracket 31. The air guiding channel 318 is used to guide cold air above the ice making grid 32, improving the ice making efficiency of the ice making grid. When the ice maker 3 is installed on the box body 1, the air guiding channel 318 is located at the rear end of the first bracket 31.

[0178] In some embodiments, referring to Figure 8 , a sterilization device 5 is connected to the first bracket 31. The sterilization device 5 includes a sterilization light source 51. The sterilization light source 51 is used to irradiate the ice storage cavity 341. The light emitted by the sterilization light source 51 can be short-wave visible light. The peak wavelength of the short-wave visible light can be A, where 400nm ≤ A and A ≤ 410nm, or 400nm ≤ A and A ≤ 420nm, or 400nm ≤ A and A ≤ 450nm. The sterilization light source 51 can be an ultraviolet sterilization light source, capable of emitting ultraviolet rays to sterilize the ice storage cavity 341 and the ice cubes in the ice storage cavity 341.

[0179] In some embodiments, the refrigerator includes a controller. The controller is electrically connected to the sterilization light source 51. The controller is configured to:

[0180] After receiving the start signal of the ice maker 3, control the sterilization light source 51 to turn on.

[0181] The ice maker 3 can be started or stopped through the display panel of the refrigerator or a mobile terminal. After the controller receives the start signal of the ice maker 3, it controls the sterilization light source 51 to turn on. The sterilization light source 51 irradiates the ice storage cavity 341 to ensure the cleanliness of the ice storage box 34. Specifically, after receiving the start signal of the ice maker 3, control the sterilization light source 51 to work intermittently with the first start-stop ratio a1, and the irradiation intensity of the sterilization light source 51 is the first intensity b1. 1 / 20 ≤ a1 and a1 ≤ 1 / 10, 0.001mW / cm 2 ≤ b1 and b1 ≤ 0.01mW / cm 2 . The time from starting the ice maker 3 to the completion of the first ice making is the first time t1, 30min ≤ t1 and t1 ≤ 150min. After the controller receives the start signal of the ice maker 3, it controls the sterilization light source 51 to work intermittently with the first start-stop ratio a1 for the second time t2. The second time t2 is less than the first time t1.

[0182] In some embodiments, the controller is configured to:

[0183] After the ice making grid 32 flips the ice, control the sterilization light source 51 to turn on to sterilize the ice storage cavity 341 and the ice in the ice storage cavity 341.

[0184] After frequently opening the door of the ice maker, microorganisms may enter the environment where the ice maker is located, which can easily lead to the growth of bacteria in the ice-making grid. After the ice-making grid flips the ice, the sterilizing light source sterilizes the ice storage cavity and the ice in the ice storage cavity, which can ensure that the ice cubes produced each time are clean, avoid the bacteria growing in the ice-making grid from contaminating the ice storage cavity and the ice cubes in the ice storage cavity. Moreover, when the sterilizing light source irradiates the ice storage cavity, it can sterilize the surface of the ice cubes, the interior of the ice cubes and the ice storage cavity, effectively improving the sterilization uniformity effect of the ice storage cavity and the ice cubes inside, and ensuring the cleanliness of the ice storage cavity and the ice cubes.

[0185] In some embodiments, referring to Figure 20 , the controller is configured to:

[0186] After the ice-making grid 32 flips the ice, determine whether the ice storage cavity 341 is full of ice; when the ice storage cavity 341 is full of ice, control the irradiation intensity of the sterilizing light source 51 to be the second intensity b2; when the ice storage cavity 341 is not full of ice, control the irradiation intensity of the sterilizing light source 51 to be the third intensity b3; where the second intensity b2 is greater than the third intensity b3. Among them, 0.1 mW / cm 2 ≤ b2, and b2 ≤ 10 mW / cm 2 . 0.01 mW / cm 2 ≤ b3, and b3 ≤ 0.1 mW / cm 2 . After the ice-making grid 32 flips the ice, determine whether the ice storage cavity 341 is full of ice, which can determine the irradiation intensity according to the amount of ice in the ice storage cavity 341, so that when there is more ice, the irradiation intensity is large enough to sterilize more thoroughly, and when there is relatively less ice, the irradiation intensity is slightly smaller, which can adapt to the amount of ice cubes, saving resources while sterilizing thoroughly.

[0187] In some embodiments, referring to Figure 20 , the controller is configured to:

[0188] When the ice storage cavity 341 is full of ice, control the sterilizing light source 51 to work intermittently with the second start-stop ratio a2; when the ice storage cavity 341 is not full of ice, control the sterilizing light source 51 to work intermittently with the third start-stop ratio a3; where the second start-stop ratio a2 is greater than the third start-stop ratio a3. Among them, 1 / 10 ≤ a2, and a2 ≤ 1 / 5. 1 / 10 ≤ a3, and a3 ≤ 1 / 8. After the ice-making grid 32 flips the ice, determine whether the ice storage cavity 341 is full of ice, which can determine the start-stop ratio of the sterilizing light source 51 according to the amount of ice in the ice storage cavity 341, so that when there is more ice, the total irradiation time is long enough to sterilize more thoroughly, and when there is relatively less ice, the total irradiation time is relatively short, saving resources while sterilizing thoroughly.

[0189] Wherein, when the ice storage chamber 341 is full of ice, the sterilization light source 51 is controlled to work intermittently at a second start-stop ratio a2 for a third time t3, 0 min < t3 and t3 ≤ 60 min, which can achieve thorough sterilization. When the ice storage chamber 341 is not full of ice, the sterilization light source 51 is controlled to work intermittently at a third start-stop ratio a3 for a fourth time t4, 0 min < t4 and t4 ≤ 60 min, which can achieve thorough sterilization.

[0190] In some embodiments, the controller is configured to:

[0191] When the ice storage chamber 341 remains full of ice for more than 24 hours, the sterilization light source 51 is controlled to turn on, and the sterilization light source 51 is controlled to work intermittently at a fourth start-stop ratio a4. The irradiation intensity of the sterilization light source 51 is a fourth intensity b4, which can thoroughly sterilize the ice in the ice storage chamber 341. 1 / 12 ≤ a4 and a4 ≤ 1 / 6. 0.1 mW / cm 2 ≤ b4 and b4 ≤ 10 mW / cm 2 .

[0192] In some embodiments, referring to Figure 7 , the ice maker 3 includes an ice probe 36. The ice probe 36 is used to detect whether the ice storage chamber 341 is full of ice. The ice probe 36 is connected to the driving member 33.

[0193] In some embodiments, the controller is configured to:

[0194] After receiving the signal that the ice storage box 34 is switched from the open position to the closed position, the sterilization light source 51 is controlled to turn on. After the ice storage box 34 is opened, the probability of bacteria entering the ice storage chamber 341 will increase. By setting that the sterilization is carried out after the controller receives the signal that the ice storage box 34 is switched from the open position to the closed position, the microorganisms entering the ice storage chamber 341 after the ice storage box 34 is opened can be eliminated, ensuring the continuous cleanliness of the ice storage chamber 341.

[0195] In some embodiments, the controller is configured to:

[0196] After receiving the signal that the ice storage box 34 is switched from the open position to the closed position, obtain the height of the ice in the ice storage chamber 341, control the sterilization light source 51 to work intermittently, and control the start-stop ratio of the intermittent operation of the sterilization light source 51 according to the height of the ice in the ice storage chamber 341, which can obtain the height of the ice in the ice storage chamber 341 and determine a better start-stop ratio according to the different amounts of ice cubes in the ice storage chamber 341, saving resources while ensuring the sterilization effect.

[0197] In some embodiments, the height of the ice in the ice storage chamber 341 is H. There are n preset heights in the controller, n ≥ 2, the first preset height is H1, and the nth preset height is H n, the first preset height H1 to the nth preset height H n gradually increases.

[0198] The controller is provided with n + 1 preset start-stop ratios. The first preset start-stop ratio is G1, and the (n + 1)th preset start-stop ratio is G n+1 , the first preset start-stop ratio G1 to the (n + 1)th preset start-stop ratio G n+1 gradually increases.

[0199] When H ≤ H1, the start-stop ratio of the germicidal light source 51 working is G1.

[0200] When H n-1 < H ≤ H n , the start-stop ratio of the germicidal light source 51 working is G n .

[0201] When H > H n , the start-stop ratio of the germicidal light source 51 working is G n+1 .

[0202] By setting multiple height intervals and setting corresponding start-stop ratios for each interval, it is possible to quickly determine a better start-stop ratio according to the height of the ice in the ice storage chamber 341 being H, which is efficient and convenient.

[0203] In some embodiments, the controller is configured to:

[0204] After receiving the signal that the ice storage box 34 is switched from the open position to the closed position, obtain the height of the ice in the ice storage chamber 341; control the irradiation intensity of the germicidal light source 51 according to the height of the ice in the ice storage chamber 341, be able to obtain the height of the ice in the ice storage chamber 341, and be able to determine a better irradiation intensity according to the different amounts of ice cubes in the ice storage chamber 341, ensuring thorough sterilization while saving resources.

[0205] In some embodiments, the height of the ice in the ice storage chamber 341 is H. The controller is provided with n preset heights, n ≥ 2, the first preset height is H1, and the nth preset height is H n , the first preset height H1 to the nth preset height H n gradually increases.

[0206] The controller is provided with n + 1 preset irradiation intensities. The first preset irradiation intensity is I1, and the (n + 1)th preset irradiation intensity is I n+1 , the first preset irradiation intensity I1 to the (n + 1)th preset irradiation intensity I n+1 gradually increases.

[0207] When H ≤ H1, the irradiation intensity of the germicidal light source 51 is I1.

[0208] When H n-1 < H ≤ H nWhen the irradiation intensity of the sterilization light source 51 is I n .

[0209] When H > H n When the irradiation intensity of the sterilization light source 51 is I n+1 .

[0210] By setting multiple height intervals and corresponding irradiation intensities for each interval, it is possible to quickly determine the optimal irradiation intensity according to the height H of the ice in the ice storage chamber 341, which is efficient and convenient.

[0211] Among them, n = 3, H1 = 3 cm, H2 = 7 cm, H3 = 10 cm. When H ≤ 3 cm, the irradiation intensity of the sterilization light source 51 is I1, 0.001 mW / cm 2 ≤ I1, and I1 ≤ 0.01 mW / cm 2 , and the start-stop ratio of the sterilization light source 51 working is G1, 1 / 20 ≤ G1, and G1 ≤ 1 / 10. When 3 cm < H ≤ 7 cm, the irradiation intensity of the sterilization light source 51 is I2, 0.01 mW / cm 2 ≤ I2, and I2 ≤ 1 mW / cm 2 , and the start-stop ratio of the sterilization light source 51 working is G 2， 1 / 10 ≤ G2, and G2 ≤ 1 / 8. When 7 cm < H ≤ 10 cm, the irradiation intensity of the sterilization light source 51 is I3, 1 mW / cm 2 ≤ I3, and I3 ≤ 5 mW / cm 2 , and the start-stop ratio of the sterilization light source 51 working is G3, 1 / 8 ≤ G3, and G3 ≤ 1 / 5. When H > 10 cm, the irradiation intensity of the sterilization light source 51 is I4, 5 mW / cm 2 ≤ I4, and I4 ≤ 10 mW / cm 2 , and the start-stop ratio of the sterilization light source 51 working is G 4， 1 / 5 ≤ G4, and G4 ≤ 1 / 2.

[0212] Among them, the visible light transmittance corresponding to different ice conditions in the ice storage chamber 341 is shown in Table 3. Short-wave visible light can better sterilize the ice at the bottom of the ice storage chamber 341.

[0213] Table 3

[0214] Ice cubes in the ice storage cavity Height H of the ice in the ice storage cavity Visible light transmittance T Single-layer ice cube H ≤ 3 cm T≥60％ Two-layer ice cube 3 cm < H ≤ 5 cm T≥40％ Full ice cube 5 cm < H ≤ 15 cm T≥30％

[0215] Among them, the sterilization light source 51 has at least one, and the irradiation intensity can be changed by controlling the number of the sterilization light sources 51 turned on. Or, the irradiation intensity can be changed by adjusting the supply current of the sterilization light source.

[0216] In some embodiments, referring to Figure 12 and Figure 19, the ice maker 3 includes a rangefinder 37. The rangefinder 37 is used to detect the height of the ice in the ice storage cavity 341. The rangefinder 37 is installed on the lamp board 53. The rangefinder 37 can be an ultrasonic rangefinder or an infrared rangefinder.

[0217] The transmitting end of the ultrasonic rangefinder emits a sound wave signal, which returns to the receiving end after being blocked by the ice. Starting from the time when the signal is transmitted, the timing immediately stops when the reflected sound wave is received. The propagation speed of the sound wave in the air is 340 m / s. According to the time t of the timer, the straight-line distance between the ice and the ultrasonic rangefinder is calculated as: S1 = 340×t / 2. The angle between the orientation of the ultrasonic rangefinder and the height direction of the cabinet 1 is the second angle β. According to the angle β between the orientation of the ultrasonic rangefinder and the height direction of the cabinet 1, the distance S2 between the ice and the ultrasonic rangefinder in the height direction of the cabinet 1 is calculated, S2 = S1×cosβ. The distance between the bottom of the ice storage cavity 341 and the ultrasonic rangefinder in the height direction of the cabinet 1 is S3, and the height of the ice in the ice storage cavity 341 is H, H = S3 - S2.

[0218] In some embodiments, referring to Figure 18 , the ice maker 3 includes an ice storage box switch. The ice storage box switch is connected to the controller. When the ice storage box 34 moves from the open position to the closed position, the ice storage box switch can send a signal to the controller, so that the controller can recognize that the ice storage box 34 moves from the open position to the closed position, and then the controller can control the sterilization light source 51 to turn on for sterilization.

[0219] Referring to Figure 18 , the ice storage box switch includes a reed switch 381 and a magnet. The reed switch 381 is connected to the first bracket 31, and the magnet is connected to the ice storage box 34. When the ice storage box 34 is closed, the magnet approaches the reed switch 381, and the magnetic field of the magnet is sufficient to close the two metal reeds inside the reed switch 381 to form an electric current path. At this time, the reed switch 381 can send a signal to the connected controller to indicate that the ice storage box 34 is closed. When the ice storage box 34 is opened, the magnet moves away from the reed switch 381, and the magnetic field of the magnet is not sufficient to keep the metal reeds in the reed switch 381 in contact, so the circuit is disconnected.

[0220] In some embodiments, the sterilization device 5 is used to sterilize the ice maker 3. The sterilization device 5 can be connected to the cabinet 1 or the cabinet door 2. The sterilization device 5 includes a pulsed lamp. The pulsed lamp can be a pulsed inert gas lamp. The pulsed inert gas lamp can be a pulsed xenon lamp.

[0221] Among them, the pulsed xenon lamp can generate pulsed intense light, which is a new type of non-thermal sterilization technology capable of inactivating microorganisms on the surface of objects. The system of pulsed intense light mainly consists of a power unit and a xenon lamp unit. The power unit provides energy for the lamp by generating high voltage and high-energy current, converting alternating current into direct current, and storing the direct current in an electrical energy storage device at the same time. When the capacitor reaches the preset level, the controller releases high-energy current to the lamp through a coaxial cable. The energy released into the lamp generates intense pulsed light, which can be directly directed at the target object to achieve the purpose of sterilization. The spectrum emitted in the pulsed light includes the ultraviolet region (200nm - 400nm), the visible region (400nm - 700nm), and the near-infrared region (800nm - 1100nm), having a similar high-power radiation pulse to the solar spectrum (200nm - 1100nm).

[0222] The sterilization mechanism of pulsed intense light is mainly divided into three aspects. One is the photothermal reaction: A part of the light of pulsed intense light has wavelengths in the visible and near-infrared bands. After this part of the light transfers heat to the surface of the object, it immediately raises the surface temperature to 50°C - 150°C, causing the cell wall of the bacteria to rupture and evaporating its cell fluid, resulting in the death of the bacteria. This instantaneous temperature rise only affects the surface of the object (about 10 mm thick) and will not significantly increase the internal temperature of the irradiated object, thus not affecting the food quality. The second is the photoreaction: After proteins, DNA, and RNA in the cells absorb ultraviolet light, they denature, and their structures also undergo physico-chemical changes, resulting in damaged genetic information, loss of replication and gene transcription functions, and ultimately leading to cell death, achieving the purpose of sterilization. The third is the photophysical effect: The strong penetration and instantaneous impact ability of pulsed intense light can destroy the cell structure, leading to the death of bacterial cells, and the sterilization effect is significant.

[0223] By using a pulsed inert gas lamp, the sterilization device 5 can emit light in the ultraviolet to infrared region that is similar to the solar spectrum but with stronger intensity, thereby being able to sterilize the ice maker 3, the ice storage box 34, and the ice cubes in the ice storage box 34.

[0224] The pulsed inert gas lamp can release high-energy intense light for sterilization within a millisecond-level time. The time acting on the surface of the object during the whole treatment process is short, so it will not damage the quality of the object.
