Description

Technical Field

[0001] The present invention relates to the technical field of humidifying equipment, and in particular to a humidifying device, a refrigerator drawer and a refrigerator. Background Art

[0002] Keeping fruits and vegetables fresh in refrigerators is a major concern for many consumers. Refrigerators have become essential household appliances primarily because they provide significant convenience. People can use weekends and holidays to stock up on all the food they need for the week (including fruits and vegetables) and store them in the refrigerator, eliminating the need to spend time shopping for fruits and vegetables on weekdays. However, because the fruit and vegetable boxes in air-cooled refrigerators lack moisture retention, fruits and vegetables (especially leafy vegetables) can dry out when stored in the refrigerator.

[0003] Currently, a humidifying device is placed in the refrigerator, and the humidity in the refrigerator drawer (fruit and vegetable box or fruit and vegetable drawer) is obtained for humidification, thereby achieving the moisturizing function of the refrigerator.

[0004] Existing humidification devices place volcanic rocks (or other porous, water-absorbing materials) in a water tank. The volcanic rocks absorb and evaporate water, achieving moisture retention and mist-free humidification. This method of placing the volcanic rocks directly into the water makes it impossible to control their position and evaporation area. If the water submerges the rocks, their evaporation effect fails, rendering the humidification device ineffective. Furthermore, if the water level is at its maximum, the rocks must remain above the surface. This means that at the lowest water level, the rocks remain at the same level as at the highest. This results in wasted rock, uncontrolled evaporation area, and poor humidification.

[0005] In summary, the humidification device in the prior art cannot control the volatilization area, resulting in poor humidification effect. Summary of the Invention

[0006] The embodiments of the present invention provide a humidifying device, a refrigerator drawer, and a refrigerator to solve the problem that the humidifying device in the prior art cannot control the volatilization area, resulting in poor humidification effect.

[0007] To achieve the above-mentioned purpose, the present invention provides a humidifying device, comprising: a box body, in which a water tank is provided; a water volatilization component, which is provided in the water tank; a magnetic component, which is connected to the water volatilization component; and an electromagnet, which is connected to the box body, and a force is generated between the electromagnet and the magnetic component.

[0008] Furthermore, it also includes: a water level sensor, which is arranged in the water tank.

[0009] Furthermore, a controller is provided, the controller is electrically connected to the water level sensor, and the controller is electrically connected to the electromagnet and controls the magnetic force of the electromagnet.

[0010] Furthermore, the electromagnet is arranged at the bottom of the box body, and the position of the electromagnet corresponds to the bottom of the water tank.

[0011] Furthermore, the magnetic element is located on the side of the water volatilization component facing the bottom of the water tank.

[0012] Furthermore, the moisture volatilizing member comprises a porous water-absorbing material.

[0013] Furthermore, the water volatilization component includes: a carrier part, the interior of the carrier part is filled with volcanic rock, and the carrier part is provided with a water inlet hole communicating with the interior; and a magnetic component is connected to the carrier part.

[0014] According to another aspect of the present invention, a refrigerator drawer is provided, comprising the above-mentioned humidifying device.

[0015] Furthermore, a humidity sensor is provided in the refrigerator drawer.

[0016] According to another aspect of the present invention, a refrigerator is provided, comprising the above-mentioned humidifying device.

[0017] The present invention utilizes the electromagnetic principle of like charges attracting and opposite charges repelling to generate a force between the electromagnet and the magnetic component. The electromagnet controls the current flowing through it according to the water level, thereby varying the magnitude of the electromagnet's magnetic force. This change in the magnitude of the electromagnet's magnetic force acts on the magnetic component and controls the movement of the water evaporation component. If the water level is high, the electromagnet's magnetic force is controlled to change, causing the component to rise above the water surface, thereby controlling the submerged level of the component and ensuring a stable evaporation area. If the water level is low or at its lowest point, the electromagnet's magnetic force is controlled to change, causing the component to lower along with the water level, thereby controlling the submerged level of the component and ensuring a constant evaporation area. Through structural coordination, the present invention effectively controls the submerged level of the component, ensuring a stable evaporation area, improving humidification effectiveness, and accelerating humidification rates. Furthermore, the predetermined humidification rate is maintained regardless of the water level within the humidifier. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0022] See also Figure 1 As shown, according to an embodiment of the present invention, a humidifying device is provided, which includes a box body 10, a moisture volatilization component 20, a magnetic component 30 and an electromagnet 40. A water tank 11 is provided in the box body 10; the moisture volatilization component 20 is provided in the water tank 11; the magnetic component 30 is connected to the moisture volatilization component 20; the electromagnet 40 is connected to the box body 10, and a force is generated between the electromagnet 40 and the magnetic component 30.

[0023] The present invention utilizes the electromagnetic principle of like charges attracting and opposite charges repelling to generate a force between the electromagnet and the magnetic component. The electromagnet controls the current flowing through it according to the water level, thereby varying the magnitude of the electromagnet's magnetic force. This change in the magnitude of the electromagnet's magnetic force acts on the magnetic component and controls the movement of the water evaporation component. If the water level is high, the electromagnet's magnetic force is controlled to change, causing the component to rise above the water surface, thereby controlling the submerged level of the component and ensuring a stable evaporation area. If the water level is low or at its lowest point, the electromagnet's magnetic force is controlled to change, causing the component to lower along with the water level, thereby controlling the submerged level of the component and ensuring a constant evaporation area. Through structural coordination, the present invention effectively controls the submerged level of the component, ensuring a stable evaporation area, improving humidification effectiveness, and accelerating humidification rates. Furthermore, the predetermined humidification rate is maintained regardless of the water level within the humidifier.

[0024] It should be noted that the magnetic poles of the electromagnet and the magnetic part can be of the same or opposite sex, and the selection is mainly based on the relative position of the electromagnet and the magnetic part. The above-mentioned forces include suction and repulsion. When the electromagnet is set above the magnetic part, it is necessary to apply suction to the magnetic part to overcome the direction of gravity. When the electromagnet is set below the magnetic part, a repulsion is applied to the magnetic part to overcome the direction of gravity. The specific connection position and connection method of the electromagnet are not limited by the present invention, as long as interaction is achieved to move the water volatilization component.

[0025] The humidifier also includes a water level sensor 50, located within the water tank 11. This sensor serves two functions: first, it monitors the water level within the tank. If the water level is too low, it notifies the user of the low water level or provides feedback to the humidifier for automatic refilling. This sensor also serves as a detection function for automatic refilling. Second, it provides real-time feedback on the water level, which directly affects the current flowing through the electromagnet. This sensor controls the position of the components that evaporate the water.

[0026] Preferably, the controller is electrically connected to the water level sensor 50, and the controller is electrically connected to the electromagnet 40 and controls the magnetic force of the electromagnet 40. The controller uses the information fed back by the water level sensor to determine whether the position of the water volatilization component needs to be adjusted. If adjustment is required, the controller determines an adjustment strategy and adjusts the current in the electromagnet or changes the magnetic pole of the electromagnet. The controller can intelligently adjust the position of the water volatilization component to ensure the volatilization area of ​​the water volatilization component.

[0027] In this embodiment, the electromagnet 40 is disposed at the bottom of the housing 10, corresponding to the bottom of the water tank 11. The electromagnet adjusts the distance between the water volatilization component and the tank bottom by varying the magnitude of the magnetic force, thereby adjusting the position of the water volatilization component (i.e., its height relative to the tank bottom).

[0028] An analysis of the forces acting on the moisture evaporation component reveals that it is subject to its own gravity G, the buoyancy of the water F1, and the magnetic force F2 of the electromagnet at the bottom of the box. The relationship is as follows: F1 + F2 = G; F2 = N * I, where N is the number of coil turns and I is the current in the coil. As can be seen, the greater the current, the greater the magnetic force of the electromagnet.

[0029] Combine Figure 1 As shown, magnetic member 30 is located on the side of water volatilization component 20 facing the bottom of water tank 11. The position of magnetic member 30 corresponds to the position of the electromagnet. This arrangement can enhance the interaction between the magnetic member and the electromagnet, thereby improving the control effect. Electromagnet 40 can be located inside the water tank or externally connected to the box body. The specific location can be selected based on actual manufacturing requirements.

[0030] Preferably, the water volatilization component 20 comprises a porous water-absorbing material, which constitutes most of the structure of the water volatilization component. The porous water-absorbing material increases the surface area for water volatilization through its porosity and accelerates water volatilization.

[0031] The moisture volatilization component 20 includes a carrier portion 21, the interior of which is filled with volcanic rock 22. The carrier portion 21 is provided with a water inlet 23 communicating with the interior, and the number of the water inlet 23 is at least one; a magnetic component 30 is connected to the carrier portion 21. The carrier portion 21 is generally of a regular shape, such as a circle or rectangle, and has notches or air vents on its surface for moisture volatilization. The material of the carrier portion 21 can be a water-absorbing material or a material such as plastic. The water inlet 23 on the carrier portion 21 ensures that water comes into contact with the volcanic rock. The magnetic component 30 can be a magnet, bonded to the carrier portion, or snapped into a slot on the carrier portion, or fixed to the carrier portion by screws or the like.

[0032] The humidifier consists of a box body and a lid. The lid is used to prevent impurities such as sand and vegetable leaves from falling into the box body. The water tank inside the box body can also be connected to the water storage device, thereby realizing water replenishment when needed.

[0033] The humidifier of this invention utilizes a porous, water-absorbing material to volatilize moisture naturally without mist, thus avoiding the problem of ultrasonic atomization humidification causing water droplets in the refrigerator compartment that can cause food spoilage. By varying the water level within the volcanic rock, the evaporation rate of the water within the rock, and thus the humidification rate of the humidifier, can be better controlled.

[0034] See also Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, a refrigerator drawer is provided, comprising the humidifying device of the above embodiment.

[0035] A humidity sensor 60 is installed inside the refrigerator drawer. The size of the humidifier's housing determines the choice of refrigerator drawer. For smaller drawers, a semi-open fruit and vegetable drawer or similar drawer space can be used to provide humidity. For larger drawers, the humidifier can accommodate the humidification of an entire refrigerator drawer or drawer assembly (i.e., the entire refrigerated space). The humidity sensor 60 is used to detect the humidity level inside the refrigerator drawer.

[0036] The refrigerator drawer will set an appropriate storage humidity level for different fruits and vegetables. Different storage humidity levels correspond to different volcanic rock immersion depths. The electromagnet is activated, the current is calculated, and the volcanic rock carrier is moved upwards based on the principle of opposite charges repelling each other. Water is added to the water tank, and the water level sensor detects the water level to maintain the volcanic rock immersion depth. When the immersion depth exceeds the set height, the current is increased, increasing the magnetic force. Water addition is stopped when the water level reaches the maximum level, and the electromagnet's magnetic force reaches its maximum. The relationship between immersion depth and storage humidity can be listed in the database as follows:

[0037] Storage humidity a％ b％ c％ d％ e％ Immersion depth H1 H2 H3 H4 H5

[0038] During the volatilization process, the humidity level in the refrigerator drawer is always detected and displayed on the display screen, which gives users a more intuitive and good experience. The water level will drop during volatilization. After the water level sensor detects the drop in water level, it reduces the current in the electromagnet and moves the volcanic rock downward to adapt to the water level.
