Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and more particularly, to a humidifying device, a fresh-keeping drawer, a refrigerator and a control method thereof. Background Art

[0002] Placing fruits and vegetables in the refrigerated compartment of a refrigerator can extend their fresh-keeping time. Therefore, refrigerators have become an essential household appliance for food preservation. Generally, the preservation of fruits and vegetables requires a relatively high humidity environment. Especially for leafy vegetables, when stored in a refrigerator, a humidity of more than 90% is required to prevent them from wilting.

[0003] Existing refrigerators already have a humidifying function. The humidity control methods mainly include passive humidification and active humidification. Passive humidification mainly relies on the evaporation of water vapor from stored items such as vegetables in the vegetable compartment to control the humidity environment in the vegetable compartment. Without an additional water source, passive humidification cannot actively humidify the fruit and vegetable compartment. When there are fewer stored items such as vegetables, it cannot maintain a high humidity environment, which may cause dehydration of the stored items such as vegetables.

[0004] Active humidification mainly supplements water vapor by controlling the external humidifying unit at regular intervals or by switching control to maintain the humidity environment in the vegetable compartment. Currently, the solutions adopted for active humidification are all to increase a humidifying device and humidify through an ultrasonic or electrochemical device. However, humidifying the compartment with water mist not only increases energy consumption but also cannot intelligently adjust the target humidity according to the types and quantities of stored items such as vegetables, and it is very easy to cause water accumulation in the compartment, resulting in the rotting of fruits and vegetables.

[0040] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0041] Embodiment 1

[0042] In a preferred Embodiment 1 of the present invention, a humidifying device is provided. Specifically, Figure 1 An optional structural schematic diagram of the device is shown, as Figure 1 shown, the device includes:

[0043] A water storage tank 10;

[0044] A water evaporation component 20, which is arranged in the water storage tank 10 and is used to absorb the water in the water storage tank 10 and evaporate it;

[0045] A humidity adjustment member 30, which is connected to the water evaporation component and is used to adjust the water absorption amount of the water evaporation component.

[0046] In the above embodiment, by arranging a water evaporation component in the water storage tank to absorb and evaporate the water in the water storage tank, the humidifying effect is achieved without increasing energy consumption, and the material can be continuously used without generating consumables, effectively solving the problem of high energy consumption in humidifying by ultrasonic or electrochemical devices in the prior art. At the same time, the humidifying device in the present invention is also provided with an adjustment member for adjusting the water absorption amount of the water evaporation component, which can maintain the humidity within the required range, prevent water accumulation due to excessive humidity, improve the intelligence level of the humidifying device, and the freshness preservation effect of the freshness preservation equipment using the humidifying device.

[0047] As Figure 1As shown in the figure, the moisture volatilization component includes: a buoyancy structure 21 that floats in the water storage tank 1; a porous water-absorbing material 22 that is disposed on the buoyancy structure 21 and is used to absorb the water in the water storage tank 10 and volatilize it. Preferably, the porous water-absorbing material 22 is volcanic rock. Volcanic rock is a natural porous material formed by magma erupting onto the earth's surface and cooling and crystallizing in the atmosphere and hydrosphere. The natural pores of volcanic rock endow it with a unique breathing function. It absorbs enough water through the pores in water, and in a low-humidity environment, the water is slowly released to adjust the humidity of the surrounding air. The volcanic rock is placed on the buoyancy structure 21, and the buoyancy structure 21 is placed in the water storage tank 1. After a certain amount of water is added to the water storage tank 1, the buoyancy structure 21 floats up, and part of the volcanic rock is exposed above the water surface. The porous structure of the volcanic rock increases the evaporation surface area, enabling it to quickly absorb water and evaporate the water through the porous structure into the space that needs to be humidified, such as the drawer of a refrigerator, thereby humidifying the drawer.

[0048] According to the humidification principle of volcanic rock, the humidification solution in the present invention does not require additional energy consumption, and the material can be continuously used without generating consumables, saving energy consumption. It is not only environmentally friendly but also reduces the cost of the humidification device. In addition, volcanic rock also has the effect of sterilizing and activating water. Volcanic rock contains rich ionic elements, which can slightly release infrared rays and alpha rays. These elements can improve the activity of water molecules and play a role in disinfection. Therefore, volcanic rock can keep the water in the humidification device clean for a long time without the need to set up a purification device, ensuring the safety of the food ingredients in the refrigerator using this humidification device.

[0049] To increase the intelligence of the humidification device, as Figure 1 shown, a humidity adjustment member 30 is connected to the buoyancy structure 21 and is used to control the up and down movement of the buoyancy structure 21, thereby adjusting the volume of the porous water-absorbing material 22 exposed above the water surface. Optionally, the humidity adjustment member 30 is a track structure and is connected to the buoyancy structure 21. The buoyancy structure 21 slides up and down on the track to adjust its height. Figure 1 The volcanic rock shown in the figure is a regular body. Adjusting the volume of the volcanic rock exposed above the water surface can be achieved by adjusting the height of the volcanic rock exposed above the water surface. If the volcanic rock used is an irregular body, its volume needs to be calculated according to the shape of the volcanic rock.

[0050] The humidification device includes a box body, and the water storage tank 10 is disposed inside the box body. The box body includes a main body 41 and a top cover 42; among them, the top cover 42 is a moisture-permeable porous material, and the moisture volatilized by the moisture volatilization component enters the environment through the moisture-permeable top cover, thereby humidifying the environment.

[0051] In addition, the humidification device further includes a fixing member 50 located on the outer side wall of the main body 41 and is used to fix the humidification device in the space that needs to be humidified, such as the fresh-keeping drawer of a refrigerator.

[0052] The above humidifying device uses natural material - volcanic rock for humidification, without the need to add consumables, which is energy - saving and environmentally friendly. At the same time, an adjusting member is provided, which can maintain the humidity within the required range, and there will be no water accumulation due to excessive humidity, improving the intelligence and humidifying effect of the humidifying device.

[0054] In the preferred Embodiment 2 of the present invention, a fresh - keeping drawer is provided, which includes the humidifying device in the above Embodiment 1. Specifically, Figures 2 to 3 An optional structural schematic diagram showing the fresh - keeping drawer is as Figure 2 and Figure 3 shown. The fresh - keeping drawer includes:

[0055] A drawer body 80 for accommodating fresh - keeping food ingredients;

[0056] A humidifying device 90 that can actively humidify the inside of the fresh - keeping drawer, which is fixed inside the fresh - keeping drawer. In this embodiment, the humidifying device is fixed on the rear panel of the drawer;

[0057] A humidity - regulating device, that is, an adjustable moisture - permeable membrane assembly 60, which is arranged on the top of the fresh - keeping drawer;

[0058] A humidity sensor 70 is arranged inside the fresh - keeping drawer, which can detect the humidity inside the fresh - keeping drawer in real time.

[0059] In the above - mentioned embodiment, by arranging a water - volatilizing component in the water storage tank to absorb and volatilize the water in the water storage tank, the humidifying effect is achieved. There is no need to increase energy consumption, and the material can be continuously used without generating consumables, effectively solving the problem of high energy consumption in humidification by ultrasonic or electrochemical devices in the prior art. At the same time, the humidifying device in the present invention is also provided with an adjusting member for adjusting the water absorption amount of the water - volatilizing component, which can maintain the humidity within the required range, and there will be no water accumulation due to excessive humidity, improving the intelligence level of the humidifying device and the fresh - keeping effect of the fresh - keeping drawer.

[0060] Figure 4 An optional structural schematic diagram showing the adjustable moisture - permeable membrane assembly is as Figure 4 shown. The adjustable moisture - permeable membrane assembly includes: a moisture - permeable membrane 61 for regulating the humidity inside the fresh - keeping drawer; the adjustable moisture - permeable membrane assembly 60 has different gears, and different gears correspond to different moisture - permeable membranes 61 with different moisture - permeability.

[0061] Among them, the adjustable moisture - permeable membrane assembly 60 further includes: a ventilation hole 63 for connecting the fresh - keeping drawer and the external space; an adjusting member 62 for adjusting the effective use area of the moisture - permeable membrane 61, and the adjusting member 62 is also used to adjust the opening and closing of the ventilation hole 63. As Figure 4As shown, optionally, the adjusting member 62 includes a fully closed state, a humidity adjustment state, a fully open state, and a ventilation state. Among them, in the fully closed state, the effective use area of the moisture permeable membrane 61 is 0%, and the ventilation hole 63 is closed; in the humidity adjustment state, the effective use area of the moisture permeable membrane 61 is between 0% and 100%, and the ventilation hole 63 is closed; in the fully open state, the effective use area of the moisture permeable membrane 61 is 100%, and the ventilation hole 63 is closed; in the ventilation state, the ventilation hole 63 is opened.

[0062] The adjustable moisture permeable membrane assembly 60 includes a substrate 64, the moisture permeable membrane 61 is installed on the substrate 64, the ventilation hole 63 is opened on the substrate 64, and the adjusting member 62 is movably arranged on the substrate 64 to adjust the effective use area of the moisture permeable membrane 61 and / or adjust the opening and closing of the ventilation hole 63.

[0063] Preferably, the adjustable moisture permeable membrane assembly 60 further includes a slide rail 65, the slide rail 65 is installed on the substrate 64, and the adjusting member 62 is slidably installed on the slide rail 65.

[0064] The adjusting member 62 is a baffle plate, the baffle plate is slidably arranged on the substrate 64, and the baffle plate adjusts the effective use area of the moisture permeable membrane 61 and / or adjusts the opening and closing of the ventilation hole 63 by means of blocking / avoiding. Through the design of the slidable baffle plate, it is more convenient to control the effective use area of the moisture permeable membrane 61 and the opening and closing of the ventilation hole 63. When it is necessary to adjust the effective use area of the moisture permeable membrane 61, the baffle plate can selectively block / avoid the acting area of the moisture permeable membrane 61 with the fresh-keeping space or the external space; when it is necessary to open the ventilation hole 63, the baffle plate is made to avoid the ventilation hole 63, and when it is necessary to close the ventilation hole 63, the baffle plate is made to block the ventilation hole 63.

[0065] Specifically, for the several states of the adjusting member 62 described above, in the fully closed state, the baffle plate moves to a position where it completely blocks the moisture permeable membrane 61 and completely blocks the ventilation hole 63; in the humidity adjustment state, the baffle plate moves to a position where it partially blocks the moisture permeable membrane 61 and completely blocks the ventilation hole 33; in the fully open state, the baffle plate moves to a position where it avoids the moisture permeable membrane 61 and completely blocks the ventilation hole 33; in the ventilation state, the baffle plate moves to a position where it avoids the ventilation hole 33. As Figure 4As shown, in the humidity adjustment state, the baffle can have two gears, and the effective area of the moisture permeable membrane 61 is different under different gears. As other alternative embodiments, the baffle can also have more gears. For example, a first state where the effective use area of the moisture permeable membrane 61 is adjusted to a%; a second state where the effective use area of the moisture permeable membrane 61 is adjusted to b%; a third state where the effective use area of the moisture permeable membrane 61 is adjusted to c%; where a < b < c; the first state corresponds to the first gear of the adjustable moisture permeable membrane assembly 60, the second state corresponds to the second gear of the adjustable moisture permeable membrane assembly 60, and the third state corresponds to the third gear of the adjustable moisture permeable membrane assembly 60.

[0094] S726: Open the ventilation hole; when the humidity W is higher than the limit humidity W1, control the humidity adjustment device to open the ventilation hole to avoid condensation due to excessive humidity. Then, proceed to step S722.

[0095] In the preferred embodiment 5 of the present invention, another refrigerator control method is also provided. Specifically, Figure 8 An optional flowchart showing this method is as Figure 8As shown, the method includes the following steps S802 - S820:

[0096] S802: Start;

[0097] S804: Record the ambient humidity W; the humidity sensor detects the humidity W in the environment, that is, the humidity inside the fresh - keeping drawer;

[0098] S806: W > W1; Determine whether W > W1 holds, where W1 is the first preset humidity. If so, go to step S808; otherwise, go to step S810. Among them, the range of the first preset humidity W1 is 92% - 100%, and the optimal value can be selected as 95%;

[0099] S808: The moisture - permeable membrane area S = S1; If the ambient humidity W is higher than the first preset humidity W1, control the humidity - regulating device to adjust the effective use area of the moisture - permeable membrane to the first preset area S1. Optionally, the first preset area S1 = S, that is, the moisture - permeable membrane is fully opened. At this time, the moisture - permeation rate of the moisture - permeable membrane is the largest, avoiding condensation after humidity saturation; then, return to step S804;

[0100] S810: W > W2; If the ambient humidity W is lower than the first preset humidity W1, then determine whether it is higher than the second preset humidity W2; If so, go to step S812; otherwise, go to step S814. Among them, the range of the second preset humidity W2 is 50% - 70%, and the optimal value can be selected as 60%;

[0101] S812: The moisture - permeable membrane area S = S2; Control the effective use area of the moisture - permeable membrane to the second preset area S2, and the second preset area S2 = 1 / 2S, that is, half of the area of the moisture - permeable membrane. At this time, the moisture - permeation rate of the moisture - permeable membrane is reduced, thus avoiding water loss and wilting of fruits and vegetables due to too low humidity. Then, return to step S804;

[0102] S814: The moisture - permeable membrane area S = S3; If the ambient humidity W is lower than the second preset humidity W2, control the effective use area of the moisture - permeable membrane to the third preset area S3, where the third preset area S3 = 0, that is, the moisture - permeable membrane is fully closed and the effective use area is 0;

[0103] S816: Calculate the humidity decrease rate V; After controlling the effective use area of the moisture - permeable membrane to the third preset area S3, calculate the humidity decrease rate V;

[0104] S818: V > V1; Determine whether V > V1 holds, where V1 is the first preset rate. If so, go to step S820; otherwise, go to step S814. The range of the humidity decrease rate threshold V1 is 1% / min - 5% / min, and the optimal value can be selected as 3% / min;

[0105] S820: Humidifying device replenishes water; if the humidity drop rate is greater than the first preset rate V1, the humidity drops too fast, and the humidifying device needs to be turned on to replenish water to prevent items to be preserved such as fruits and vegetables from losing water. Then, return to step S804.

[0106] By obtaining the target humidity of the fresh-keeping drawer, and then adjusting the volume of the water evaporation component of the humidifying device exposed to the water surface, and / or the effective use area of the adjustable moisture-permeable membrane assembly of the fresh-keeping drawer according to the target humidity, the humidity can be maintained within the required range, and water accumulation will not occur due to excessive humidity, improving the intelligence of the humidifying device and the fresh-keeping effect of the refrigerator.
