Description

Technical Field

[0001] The present application relates to the field of home appliances, and more specifically, to a storage cabinet and a refrigerator. Background Art

[0002] Refrigerators are used to preserve food freshness and extend its shelf life. We typically store food or items with a short shelf life in the refrigerator, including unfinished meals. The odors of food and other foods, especially leftover food, can mingle and permeate the space, affecting the flavor of other refrigerated foods. Many fresh vegetables and meats contain nitrates, but if left at room temperature for too long, they can easily breed bacteria. These bacteria then convert the nitrates in food into nitrites. If cooked vegetables and meats are not refrigerated or are refrigerated for too long, bacteria can also convert nitrates into nitrites.

[0003] Nitrite will produce a series of reactions in the human body, causing the normal oxygen-carrying low-iron hemoglobin in the blood to be oxidized into high-iron hemoglobin, thereby losing its oxygen-carrying capacity and causing tissue hypoxia. Long-term consumption of foods high in nitrite can even induce cancer, and the secondary products of nitrite and protein react to form nitrosamines, which are carcinogenic. Utility Model Content

[0039] This application provides a locker, please refer to Figure 1 and Figure 2 The locker includes a locker body 100, a shelf 200 and a controller (not shown in the figure). A accommodating cavity 110 is formed inside the locker body 100, and the locker body 100 includes at least a top wall 111 and a bottom wall 112 relative to each other. At least one shelf 200 is arranged facing the top wall 111, and the shelf 200 can be parallel to and opposite the top wall 111. The direction in which the top wall 111 points to the bottom wall 112 is the first direction, that is, the height direction of the locker body 100, and the shelf 200 is movably arranged in the accommodating cavity 110 along the first direction. That is, the shelf 200 divides the accommodating cavity 110 into an upper space facing the top wall 111 and a lower space facing the bottom wall 112. The shelf 200 can move along the first direction, that is, the size of the upper space and the lower space can be adjusted.

[0040] The degradation device is used to release degradation substances to the side of the shelf 200 facing the top wall 111. The shelf 200 is used to place food, and the degradation substances released from the degradation device can suppress the amount of nitrite generated in the food placed on the shelf 200. The storage cabinet also includes a controller, which is used to control the shelf 200 to move in a first direction. A first measuring sensor is provided on the shelf 200, and the first measuring sensor is electrically connected to the controller. The first measuring sensor is used to measure information about the food placed on the shelf 200 and output a first measurement signal to the controller. The controller controls the shelf 200 to move in the first direction according to the first measurement signal. The first measuring sensor can be a pressure sensor, so that the measured first measurement signal can be the weight information of the food placed on the shelf 200. The controller can control the shelf 200 to move in the first direction according to the weight of the food placed on the shelf 200 and adjust the size of the upper space of the shelf 200.

[0041] The heavier the food, the greater the amount of nitrite produced. When the controller receives that the food on the rack 200 is heavier, it can control the rack 200 to move toward the top wall 111, compressing the size of the upper space of the rack 200. By releasing an equal amount of degradable substances, the volume of the upper space of the rack 200 is reduced, and the concentration of the degradable substances is increased, which can further reduce the nitrite content in the food with a larger mass. Similarly, when the weight of the food is smaller, the controller can control the rack 200 to move toward the bottom wall 112, increasing the volume of the upper space of the rack 200, so that foods of different weights are in an atmosphere with a suitable concentration of degradable substances.

[0042] Alternatively, the first measurement sensor can be a food type sensor, such as an image sensor, to identify the type of food placed on the rack 200 and adjust the rack 200 accordingly. For example, if meat produces nitrites at a faster rate and in higher quantities, the rack 200 can be controlled to move toward the top wall 111 to increase the concentration of nitrite-reducing substances in the upper space. Alternatively, if root vegetables produce nitrites at a slower rate and in lower quantities than meat, the rack 200 can be controlled to move toward the bottom wall 112.

[0043] In summary, this embodiment not only effectively reduces the amount of nitrite in food placed in the storage cabinet and prolongs the storage time of food, but also can further control the movement of the shelf 200 according to the type and / or quality of the food, thereby controlling the size of the upper space of the shelf 200 to adapt to the type and / or quality of the food, thereby increasing the efficiency of degrading substances and reducing the nitrite content in the food. The degrading substances can be in the form of aerosol, liquid, or powder. The degrading substances can include tea polyphenols, organic sulfides contained in onions, vitamin C in fruits and vegetables, niacinamide, lactic acid bacteria, and enzymes capable of degrading nitrite.

[0044] Please combine Figure 3 The rack 200 is movable in a first direction. Specifically, a lifting device 210 can be provided between the rack 200 and the storage cabinet. The two ends of the rack 200 are movably connected to the storage cabinet via the lifting device 210. The lifting device 210 can drive the rack 200 to move upward and downward in the first direction. The lifting device 210 is connected to a transmission mechanism, which is connected to a drive device. The drive device is electrically connected to a controller. The controller controls the drive device, and the transmission device transfers kinetic energy to the lifting device 210, thereby controlling the lifting device 210 to control the movement of the rack 200 in the first direction. The degradation device can also be a through hole, a nozzle, or the like.

[0045] In one embodiment, the degradation device releases the degradation substance through a first through hole 300. The first through hole 300 can be located on a side of the top wall 111 facing the shelf 200. The first through hole 300 is used to release the degradation substance, while the shelf 200 is used to store food. The degradation substance released from the first through hole 300 can suppress the formation of nitrites in the food placed on the shelf 200. Multiple first through holes 300 are provided, and each of the first through holes 300 can release the degradation substance. The multiple first through holes 300 are configured to open and close under the control of the controller. The multiple first through holes 300 can be connected to a movable cover that can be opened and closed by a drive device electrically connected to the controller, which controls the opening and closing of the multiple first through holes 300 by controlling the drive device. Alternatively, the first through holes 300 can be provided with an electric valve to control the opening and closing of the first through holes 300. The multiple first through holes 300 are distributed in a lattice pattern on the side of the top wall 111 facing the shelf 200.

[0046] The first measuring sensor is also used to measure the spatial position of the food placed on the shelf 200, and output a second measurement signal to the controller. The spatial position may include the occupied area and the position. The controller controls part of the first through holes 300 to open according to the second measurement signal, wherein part of the first through holes 300 corresponds to the spatial position of the food placed on the shelf 200. For example, the first measuring sensor may be a pressure sensor, and the controller analyzes the area of ​​the outline of the food placed on the shelf 200, the position of the food and other information by analyzing the pressure values ​​at different positions. The multiple first through holes 300 in a dot matrix can be marked according to coordinates, and the controller controls the opening of the first through holes 300 that are opposite to the spatial position of the food according to the spatial information of the food. This achieves accurate release of degradation substances, reduces the consumption of degradation substances, and improves the efficiency of reducing the nitrite content in food.

[0047] In one embodiment, please refer to Figure 2 A first pipe 400 is fixed to the side of the top wall 111 facing the shelf 200, and the first through hole 300 is opened along the extension direction of the first pipe 400. The first pipe 400 is used to transport degradation substances to multiple first through holes 300. A plurality of first pipes 400 can be provided in parallel with each other, covering the top wall 111. The first pipe 400 can also be a pipe that is arranged in multiple rows in a winding manner, and each section is parallel to each other. The first through holes 300 are opened along the extension direction of the first pipe 400, which facilitates the arrangement of multiple first through holes 300 in a lattice shape on the top wall. The first pipe 400 connects multiple first through holes 300, and the degradation substances are transported to the multiple first through holes 300 through the first pipe 400 and released from the first through holes 300, providing a channel for the transportation of the degradation substances.

[0048] In one embodiment, a second through hole (not shown) is provided on the side of the rack 200 facing the bottom wall 112 , and the second through hole is used to release the degradable substance; the degradable substance is the food dispersed on the bottom wall 112 from the side of the rack 200 facing the bottom wall 112 .

[0049] A second measuring sensor is provided on the bottom wall 112 and is electrically connected to the controller. The second measuring sensor is used to measure information about the food placed on the bottom wall 112 and output a third measurement signal to the controller. The controller then controls the movement of the rack 200 in the first direction based on the third measurement signal. Similar to the first measuring sensor, the second measuring sensor can measure the type and weight of the food placed on the bottom wall 112. The controller controls the movement of the rack 200, changing the lower space of the rack 200, i.e., the space where the food on the bottom wall 112 is located, thereby changing the concentration of degradable substances in the lower space. The controller then determines the appropriate position for the rack 200 to move to based on the specific type and weight of the food placed on the bottom wall 112.

[0050] The controller can further perform a comprehensive analysis based on the first and third measurement signals. Based on the food placed on the rack 200 and the bottom wall 112, and the type and weight ratio of the food in the two sections, the controller can control the required concentration ratio of the degradable substances in the upper and lower spaces of the rack 200 to match the information relationship of the food placed in the two sections. When food is placed on both the rack 200 and the bottom wall 112, the controller controls the rack 200 to be in an appropriate position, taking into account the relationship between the two sections of food.

[0051] In one embodiment, a plurality of second through holes are provided and distributed in a matrix pattern on a side of the rack 200 facing the bottom wall 112. The plurality of second through holes are configured to open and close under the control of a controller. The second through holes can be provided with a cover plate and a drive device similar to those of the first through holes 300. The controller controls the drive device to drive the cover plate to open or close the second through holes.

[0052] The second measurement sensor is also used to measure the spatial position of food placed on bottom wall 112 and output a fourth measurement signal to the controller. The controller controls the opening of a portion of the second through-holes based on the fourth measurement signal, wherein the portion of the second through-holes corresponds to the spatial position of the food placed on the bottom wall. Similar to the first measurement sensor, the second measurement sensor can be a pressure sensor. It measures the contour and position of the food placed on bottom wall 112, and the controller controls the opening of the portion of the second through-holes directly opposite the spatial position of the food. This allows for the precise release of degradation substances from the food placed on bottom wall 112, reducing the consumption of degradation substances and improving the efficiency of reducing the nitrite content in the food.

[0053] In one embodiment, a second conduit is fixed to the bottom-facing side of the rack 200. Multiple second through-holes are defined along the extension of the second conduit. The second conduit is used to transport the degradable substance to the multiple second through-holes. The second conduit can also be multiple parallel conduits, or a single, winding conduit with multiple parallel sections. The second conduit can be configured such that the second through-holes are distributed in a lattice pattern on the bottom-facing side of the rack 200. The second conduit provides a pathway for transporting the degradable substance to the multiple second through-holes.

[0054] In one embodiment, please refer to Figure 4 , the storage cabinet further includes a first preparation device 500, which includes at least a culture device 510 and a transport pump 520 that are interconnected;

[0055] Take, for example, a strain of bacteria that can reduce nitrites, such as lactic acid bacteria. The culture device 510 is provided with a solute inlet 511 and a solvent inlet 512. The solute inlet 511 is used to introduce a solid solute that reduces nitrites, which can be a lyophilized lactic acid bacteria solution, into the culture device 510. The solvent inlet 512 is used to introduce a liquid solvent, such as a sodium chloride solution with a concentration of 5%-10%, into the culture device 510. The culture device 510 is used to mix the solid solute that reduces nitrites and the liquid solvent and prepare a nitrite-reducing solution. The specific culture device 510 may include an agitator and a culture tank. The agitator may be a magnetic agitator, a propeller agitator, a turbine agitator, or the like. The agitator is used to mix the lyophilized lactic acid bacteria solution and sodium chloride into a lactic acid bacteria solution. The culture tank can be designed with different temperature, humidity, and other environments according to the bacteria to be cultured to activate the solution. For the lactic acid bacteria solution, the culture tank can be a constant temperature culture tank, the temperature of which is designed to be a fermentation temperature suitable for the growth of lactic acid bacteria, so as to activate the lactic acid bacteria in the lactic acid bacteria solution.

[0056] The transport pump 520 is also connected to the first through hole 300 and is used to transport the reduced nitrite solution, delivering the cultured reduced nitrite solution to the first through hole 300 and releasing it onto the food from the first through hole 300. The first preparation device 500 can be positioned anywhere between the refrigerator liner and the refrigerator housing. The transport pump 520 can also be connected to the second through hole. This embodiment provides a device for preparing degradable substances, which can be prepared according to the usage and can be used directly after preparation.

[0057] In one embodiment, the first preparation apparatus 500 further includes a gasification device 530, which is disposed between the transport pump 520 and the first through hole 300 and communicates with the transport pump 520 and the first through hole 300. The transport pump 520 is configured to input the reduced nitrite solution into the gasification device 530. The gasification device 530 is configured to atomize the reduced nitrite solution into a reduced nitrite gas. In this embodiment, the solution is further atomized into a gas, resulting in more uniform dispersion, ensuring more even contact between the degrading substances and the food, and achieving a better effect in reducing nitrite in the food.

[0058] The gasification device 530 may include at least a sprayer 531 and an aerosol chamber 532. The nitrite-reducing liquid passes through the sprayer 531 and is atomized into nitrite-reducing gas in the aerosol chamber 532. The sprayer 531 may compress the nitrite-reducing solution and spray it out in a mist form to form nitrite-reducing gas in the aerosol chamber.

[0059] In one embodiment, please refer to Figure 2The storage cabinet further includes a liquid reservoir 600 for storing liquid solvents and is connected to the solvent inlet 512. For example, the liquid reservoir 600 stores sodium chloride solution as a culture solution, and the sodium chloride solution can enter the culture device 510 through the solvent inlet 512.

[0060] The liquid reservoir 600 also includes a liquid filling port and a liquid level gauge, and the liquid filling port faces the accommodating chamber. The user can add solvent directly to the liquid reservoir 600 through the liquid filling port in the accommodating chamber. The liquid level gauge is electrically connected to the controller, and the liquid level gauge is used to provide liquid level information to the controller. When the liquid level gauge detects that the amount of solvent in the liquid reservoir 600 is insufficient and less than a preset value, the controller can prompt the user that the liquid reservoir 600 needs to be filled with solvent based on the liquid level information. The controller can be electrically connected to a reminder device such as a buzzer and an indicator light to send a reminder signal. The liquid reservoir 600 can be detachably connected to the storage cabinet, and when the solution needs to be replenished, the liquid reservoir 600 can also be disassembled and replenished.

[0061] In one embodiment, please refer to Figure 2 and Figure 5 The locker also includes a storage box 120, which is used to store reduced nitrite solids and is connected to the solute inlet 511. For example, the storage box 120 stores a freeze-dried lactic acid bacteria agent. The side wall of the locker includes a groove 130 for placing the storage box 120, and the inner wall of the groove 130 is provided with a slide rail 131. The storage box 120 is detachably arranged in the groove 130 along the slide rail 131. In this embodiment, firstly, it can reduce the storage box 120 from occupying the accommodating cavity, and secondly, it is convenient to disassemble the storage box 120 to replenish the reduced nitrite solids. The storage box 120 is connected to the solute inlet 511, and can provide solid solutes to the culture device 510. The slide rail can be a pulley rod, and the storage box 120 slides in the extension direction of the pulley rod.

[0062] The liquid reservoir 600 and the storage box 120 can provide the culture device 510 with solutions and solutes in a proportional and quantitative manner, thereby avoiding waste of raw materials.

[0063] In one embodiment, please refer to Figure 1 The storage cabinet further includes a door body 140 , which is press-connected to the storage cabinet. The door body 140 opens after being pressed and is configured to open toward the outside of the accommodating cavity, so that the door body can avoid interfering with the movement of the shelf 200 .

[0064] Please refer to Figure 6 The present application also provides a refrigerator comprising any of the above-mentioned storage cabinets. Food can be placed in the storage cabinet to reduce the amount of hypotensive nitrates in the food and extend the shelf life of the food.
