Abstract
Description
Technical Field
[0001] This disclosure relates to the field of home appliance technology, and in particular to a humidity-controlled storage container, a refrigerator, and a humidity-controlled method. Background Technology
[0002] With the development of society and the economy and the improvement of people's living standards, refrigerators have gradually become an indispensable household appliance. As intelligent technology continues to expand into the home appliance field, consumers are increasingly demanding ease of use and intelligent features in their appliances. Refrigerators are equipped with humidity-controlled compartments for storing fruits, vegetables, and other foods that require specific humidity levels. As a fundamental intelligent function of refrigerators, the humidity-controlled compartment is being used more and more widely.
[0003] In related technologies, a humidity-controlled drawer is installed in the refrigerator compartment to create a humidity-controlled zone. However, condensation is prone to occur in the humidity-controlled drawer, resulting in a poor user experience. Summary of the Invention
[0004] In view of this, the present disclosure provides a humidity-controlled storage container, a refrigerator, and a humidity control method, which can adaptively adjust the humidity inside the humidity-controlled storage container to reduce condensation and improve the user's refrigerator experience.
[0005] Specifically, this disclosure is achieved through the following technical solution:
[0006] According to a first aspect of the present disclosure, a humidity-controlled storage container is provided, comprising a housing and a humidity-controlled assembly. The housing has a storage cavity and a moisture-permeable hole communicating with the storage cavity. The humidity-controlled assembly includes a dehumidifying fan installed in conjunction with the moisture-permeable hole and a humidity sensor connected to the housing, the humidity sensor also being electrically connected to the dehumidifying fan. The humidity sensor has an open state that deforms with changes in absorbed moisture and a reset state that returns to its original shape. When the humidity in the storage cavity increases, the humidity sensor is in the open state to connect the circuit to the dehumidifying fan, activating the dehumidifying fan to remove moisture from the storage cavity. When the humidity in the storage cavity decreases, the humidity sensor is in the reset state to disconnect the circuit to the dehumidifying fan, turning off the dehumidifying fan and keeping the storage cavity moist.
[0007] The technical solution of this disclosure will be further explained below:
[0008] In one embodiment, the humidity control component further includes a connecting contact point connected to the housing and a mating contact point connected to the humidity sensor. The connecting contact point and the mating contact point are spaced apart from each other, and both are electrically connected to the dehumidifying fan. When the humidity sensor is in the open state, it drives the mating contact point to contact the connecting contact point to connect the circuit. When the humidity sensor is in the reset state, it drives the mating contact point to separate from the connecting contact point to disconnect the circuit.
[0009] In one embodiment, the humidity sensor includes a fixed portion connected to the housing and a deformable portion connected to the fixed portion and spaced apart from a connecting contact point, with a mating contact disposed on the deformable portion. As the absorbed moisture increases, the deformable portion extends along the direction from the fixed portion toward the connecting contact point, thereby causing the mating contact to contact the connecting contact point. As the absorbed moisture decreases, the deformable portion returns to its original position along the direction from the connecting contact point toward the fixed portion, thereby causing the mating contact to separate from the connecting contact point.
[0010] In one embodiment, the deformable part softens as the amount of water absorbed increases, and the deformable part is driven by gravity to move the mating contact towards the connecting contact and make contact; the deformable part resets as the amount of water absorbed decreases, thereby causing the mating contact to separate from the connecting contact.
[0011] In one embodiment, the humidity control component further includes a pressure regulating component electrically connected between one of the mating contact and the connecting contact and the dehumidifying fan, so as to adjust the dehumidification speed of the dehumidifying fan when the humidity sensor is turned on.
[0012] In one embodiment, the resistance of the voltage regulator connected to the connection circuit is negatively correlated with the extension length of the humidity sensor, and / or the dehumidification speed of the dehumidifying fan is positively correlated with the extension length of the humidity sensor.
[0013] In one embodiment, the voltage regulating component includes a sliding rheostat. The fixed terminal of the sliding rheostat is electrically connected to the dehumidifying fan, and the sliding terminal of the sliding rheostat is electrically connected to one of a connecting contact and a mating contact. When the humidity sensor is in the open state, the sliding terminal moves toward the fixed terminal to decrease the resistance of the sliding rheostat. When the humidity sensor is in the reset state, the sliding terminal moves away from the fixed terminal to increase the resistance of the sliding rheostat.
[0014] In one embodiment, the connecting contact point is slidably connected to the housing. When the humidity sensor is in the open state, it pushes the mating contact point to contact the connecting contact point and pushes the connecting contact point to slide relative to the housing, thereby causing the sliding terminal to move relative to the fixed terminal.
[0015] In one embodiment, the housing is further provided with a cold air hole communicating with the storage cavity. The humidity-controlled storage container also includes a controller electrically connected to the dehumidifying fan and a refrigeration fan electrically connected to the controller. The refrigeration fan blows cold air into the storage cavity through the cold air hole. The controller adjusts the refrigeration speed of the refrigeration fan according to the dehumidification speed of the dehumidifying fan, and the dehumidification speed of the dehumidifying fan is negatively correlated with the refrigeration speed of the refrigeration fan.
[0016] In one embodiment, the deformation humidity range of the humidity sensor is set to 80% to 95%, and the full recovery deformation humidity range of the humidity sensor is set to 20% to 60%.
[0017] According to a second aspect of the present disclosure, a refrigerator is provided, including a cabinet and any of the above-described humidity-controlled storage containers. The cabinet has a refrigerator compartment, and a shell is disposed inside the refrigerator compartment. The shell is reciprocating relative to the cabinet to open or close the storage compartment.
[0018] According to a third aspect of the present disclosure, a humidity control method is provided, implemented using any of the above-described humidity control storage containers, comprising the following steps:
[0019] The humidity sensor switches between open and reset states based on changes in humidity within the storage compartment.
[0020] When the humidity inside the storage cavity increases, the humidity sensor absorbs more moisture and extends its length. The humidity sensor is in the open state to conduct the connection circuit with the dehumidifier fan. The dehumidifier fan is then activated, expelling the moisture inside the storage cavity through the moisture vent to reduce the humidity inside the storage cavity.
[0021] When the humidity in the storage cavity decreases, the humidity sensor absorbs less water and gradually recovers its deformation. The humidity sensor is in a reset state, disconnecting the circuit with the dehumidifier. The dehumidifier is turned off, and the moisture in the storage cavity is not discharged through the moisture vent, thus keeping the storage cavity moisturized.
[0022] The technical solution provided in this disclosure has at least the following beneficial effects:
[0023] The humidity-controlled storage container provided in this disclosure, when in use, allows the humidity sensor to change length according to changes in humidity within the storage cavity, thus establishing an open state and a reset state. Specifically, if the humidity within the storage cavity increases, the humidity sensor absorbs more moisture, causing it to expand and extend into the open state. This activates the circuit connecting to the dehumidifier fan, driving it to start and open the vent hole. At this time, moisture within the storage cavity can escape through the vent hole, dissipating excess moisture and reducing humidity, thereby preventing condensation on the cavity walls. If the humidity within the storage cavity decreases, the moisture absorbed by the humidity sensor also decreases, causing it to gradually return to its reset state. This disconnects the circuit connecting to the dehumidifier fan, shutting it off and closing the vent hole. In this state, moisture cannot escape through the vent hole, thus maintaining humidity within the storage cavity and preventing food from wilting.
[0024] When the humidity-controlled storage container of this disclosure is installed in a refrigerator, the shell can be connected to the refrigerator body and placed inside the refrigerator compartment to create a low-temperature environment within the storage cavity. The storage cavity of the shell can be used to store fruits and vegetables. When a large quantity of fruits and vegetables are stored in the cavity, the strong transpiration of the produce increases the humidity. In this high-humidity environment, the humidity sensor extends, activating the circuit connecting to the dehumidifier fan, which then drives the fan to start operating. This opens the ventilation holes to expel moisture from the storage cavity, preventing condensation from forming on the cavity walls. Simultaneously, the expulsion of moisture through the ventilation holes reduces the humidity within the storage cavity, promoting evaporation of water from the surface of the fruits and vegetables and preventing the growth of bacteria and mold, which could lead to spoilage. When the amount of fruits and vegetables stored in the storage cavity is small, the transpiration of the fruits and vegetables is weak, and the humidity in the storage cavity decreases. The humidity sensor recovers its deformation in the low humidity environment, disconnects the connection circuit between the sensor and the dehumidifier fan, and shuts off the dehumidifier fan, thereby closing the vent hole to prevent moisture in the storage cavity from being discharged through the vent hole. This keeps the storage cavity moist and prevents the fruits and vegetables from drying out and wilting due to the decrease in humidity.
[0025] Thus, the humidity-controlled storage container provided by this disclosure can adaptively adjust the humidity inside the storage cavity to keep the cavity moist in low-humidity conditions, thereby extending the storage time of the food inside. Simultaneously, the humidity-controlled storage container provided by this disclosure can also expel excess moisture from the storage cavity in high-humidity conditions through adaptive humidity control, reducing condensation and improving the user experience. Therefore, the humidity-controlled storage container provided by this disclosure can both keep fruits and vegetables moist to prolong their freshness and prevent condensation.

Detailed Implementation
[0047] The technical solutions in the embodiments (or "implementations") of this disclosure will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0048] If any terms relating to directional indications or positional relationships are used in the embodiments of this disclosure (e.g., up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications or positional relationships will also change accordingly.
[0049] With the development of society and the economy and the improvement of people's living standards, refrigerators have gradually become an indispensable household appliance. As refrigerator functions have diversified, there are numerous types and brands available, giving consumers a wide range of choices. Simply improving the cold-keeping characteristics of refrigerators is no longer sufficient to meet people's demands. The intelligence of refrigerators has also become an important factor influencing their competitiveness. Among refrigerators with similar functions or performance, those with higher levels of intelligence are more attractive to consumers.
[0050] Among these features, refrigerators include humidity-controlled compartments for storing fruits, vegetables, and other foods that require specific humidity levels, thus extending their shelf life. As a fundamental function of smart refrigerators, the humidity-controlled compartment is becoming increasingly widespread and is gaining popularity among consumers.
[0051] For example, most fruits and vegetables prefer to be stored in a low-temperature, high-humidity environment to prolong their freshness. Refrigerators in this technology typically have a humidity-controlled drawer in the refrigerator compartment to create a humidity-controlled zone. These refrigerators often use sealed drawers (e.g., sealing the drawer edges with a sealing strip) to achieve moisture retention. However, an overly sealed environment can cause condensation to form in the drawer during the cooling process. Therefore, these refrigerators also use moisture-permeable holes or membranes to prevent condensation. However, when the amount of fruits and vegetables in the drawer is small, moisture can still escape from the outside through the moisture-permeable holes or membranes, resulting in insufficient humidity inside the drawer, causing the fruits and vegetables to wilt and affecting the user experience.
[0052] Therefore, this disclosure provides a humidity-controlled storage container that can adaptively adjust the opening and closing of the moisture-permeable vents according to the amount of fruits and vegetables stored in the humidity-controlled drawer, thereby regulating the humidity environment inside the drawer. This allows for moisture retention of fruits and vegetables in low-humidity conditions, extending their freshness, while simultaneously expelling excess moisture in high-humidity conditions to reduce condensation and improve the user experience. Furthermore, the humidity-controlled storage container provided by this disclosure is not limited to use in household refrigerators; it can also be used in freezers or commercial refrigerators, and this disclosure makes no limitation.
[0053] The humidity-controlled storage container provided in this disclosure will now be described in conjunction with the accompanying drawings.
[0054] See Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a humidity-controlled storage container 100 according to one embodiment. Figure 2 for Figure 1 The cross-sectional view of the humidity-controlled storage container 100 shown at point AA (humidity sensor 122 is in the reset state). Figure 3 for Figure 2 The diagram shows the structure of the humidity sensor 122 in the open state. The humidity-controlled storage container 100 provided in this disclosure includes a housing 110 and a humidity control assembly 120. The housing 110 has a storage cavity 111 and a moisture-permeable hole 112 communicating with the storage cavity 111. The humidity control assembly 120 includes a dehumidifying fan 121 installed in conjunction with the moisture-permeable hole 112 and a humidity sensor 122 connected to the housing 110. The humidity sensor 122 is also electrically connected to the dehumidifying fan 121. The humidity sensor 122 has an open state that deforms with changes in absorbed moisture and a reset state that returns to its original shape. When the humidity in the storage cavity 111 increases, the humidity sensor 122 is in the open state to connect the circuit with the dehumidifying fan 121, activating the dehumidifying fan 121 to expel moisture from the storage cavity 111. When the humidity inside the storage cavity 111 decreases, the humidity sensor 122 is in a reset state to disconnect the connection circuit with the dehumidifier 121, turn off the dehumidifier 121, and keep the storage cavity 111 moisturized.
[0055] It should be noted that the shell 110 can be configured as a one-piece molded structure or as a spliced assembly structure. The shape of the shell 110 can be set according to requirements, and the material of the shell 110 is a low-temperature resistant and corrosion-resistant material, such as glass, plastic, or metal. This disclosure does not limit the shape, material, or assembly method of the shell 110. The storage cavity 111 provided in the shell 110 is used to store fruits and vegetables, and the moisture permeability hole 112 provided in the shell 110 can be used to exchange gases inside and outside the storage cavity 111 to prevent condensation and for humidity control. The number of moisture permeability holes 112 can be one or more, and this disclosure does not limit it.
[0056] The humidity control assembly 120 includes a dehumidifying fan 121 and a humidity sensor 122. The dehumidifying fan 121 is installed in conjunction with a vent 112. When the dehumidifying fan 121 is off, it seals the vent 112; when the dehumidifying fan 121 is on, it opens the vent 112, allowing moisture in the storage cavity 111 to be discharged through the vent 112. The humidity sensor 122 is electrically connected between the dehumidifying fan 121 and the housing 110. The humidity sensor 122 has the ability to elongate and deform as the humidity in the storage cavity 111 increases, and to recover its shape as the humidity in the storage cavity 111 decreases. The humidity sensor 122 can be a humidity-sensitive material, which can elongate a certain distance after absorbing more water and recover its shape after absorbing less water. Optionally, the humidity sensor 122 can be polyurethane, hydrogel, or other polymer composite materials, etc., and this disclosure is not limited thereto.
[0057] The dehumidifier fan 121 and the humidity sensor 122 may be connected by a connecting wire and a power supply to achieve electrical connection between the dehumidifier fan 121 and the humidity sensor 122. The specific electrical connection method is not limited in this disclosure.
[0058] After the dehumidifier 121 is electrically connected to the humidity sensor 122, the humidity sensor 122 can function as a circuit switch. Specifically, if the humidity inside the storage cavity 111 increases, the humidity sensor 122 absorbs more moisture from the storage cavity 111. The humidity sensor 122 can then expand and open, thus activating the circuit between itself and the dehumidifier 121. This activates the dehumidifier 121, opening the vent hole 112. At this time, the moisture inside the storage cavity 111 can escape through the vent hole 112, dissipating excess moisture and reducing the humidity inside the storage cavity 111, thereby preventing condensation from forming on the walls of the storage cavity 111. If the humidity in the storage cavity 111 decreases, the moisture absorbed by the humidity sensor 122 in the storage cavity 111 also decreases. The humidity sensor 122 gradually recovers its deformation and is in a reset state, which disconnects the connection circuit with the dehumidifier 121 to turn off the dehumidifier 121, thereby closing the moisture vent 112. At this time, the moisture in the storage cavity 111 cannot escape through the moisture vent 112, thus keeping the storage cavity 111 moist and preventing the food from wilting.
[0059] Thus, the humidity-controlled storage container 100 provided in this disclosure can sense the humidity changes in the storage cavity 111 by setting a humidity sensor 122. Through the elongation deformation of the humidity sensor 122 in a high humidity environment and the recovery deformation in a low humidity environment, the connection circuit between the humidity sensor 122 and the dehumidification fan 121 can be connected or disconnected, thereby opening or closing the moisture permeation hole 112 and adaptively adjusting the humidity in the storage cavity 111. This achieves the effect of extending the storage time of food in the storage cavity 111 in a low humidity state and reducing condensation in a high humidity state.
[0060] When the humidity-controlled storage container 100 of this disclosure is installed in a refrigerator 1, the shell 110 can be connected to the cabinet 20 and placed in the refrigerator compartment of the cabinet 20 to create a low-temperature environment in the storage cavity 111. The storage cavity 111 of the shell 110 can be used to store fruits and vegetables. When there are many fruits and vegetables stored in the storage cavity 111, the transpiration of the fruits and vegetables is strong, and the humidity in the storage cavity 111 increases. The humidity sensor 122 extends in the high humidity environment, and conducts the connection circuit between the humidity sensor and the dehumidifier 121 to drive the dehumidifier 121 to start running, thereby opening the moisture vent 112 to discharge the moisture in the storage cavity 111 and prevent excess moisture from forming condensation on the wall of the storage cavity 111. At the same time, after the moisture is discharged through the moisture vent 112, the humidity in the storage cavity 111 can be reduced, which is conducive to the evaporation of water on the surface of fruits and vegetables and prevents bacteria and mold from growing on the surface of fruits and vegetables, thus preventing the fruits and vegetables from rotting. When the amount of fruits and vegetables stored in the storage cavity 111 is small, the transpiration of the fruits and vegetables is weak, resulting in a decrease in humidity within the storage cavity 111. The humidity sensor 122 recovers its deformation under low humidity conditions, disconnecting the connection circuit with the dehumidifying fan 121 to shut it off. This closes the vent hole 112, preventing moisture from escaping from the storage cavity 111 through the vent hole 112, thus maintaining humidity in the storage cavity 111 and preventing the fruits and vegetables from drying out and wilting due to reduced humidity. Therefore, the humidity-controlled storage container 100 provided in this disclosure can both maintain the moisture of fruits and vegetables to prolong their freshness and prevent condensation.
[0061] See Figure 2 and Figure 3 , Figure 2 for Figure 1 The cross-sectional view of the humidity-controlled storage container 100 shown at point AA (humidity sensor 122 is in the reset state). Figure 3 for Figure 2 The diagram shows the humidity sensor 122 in the open state. In some embodiments, to facilitate the connection circuit between the humidity sensor 122 and the dehumidifier 121, the humidity control assembly 120 further includes a connecting contact 123 connected to the housing 110 and a mating contact 124 connected to the humidity sensor 122. The connecting contact 123 and the mating contact 124 are spaced apart from each other, and are electrically connected to the dehumidifier 121. When the humidity sensor 122 is in the open state, it causes the mating contact 124 to contact the connecting contact 123 to connect the circuit. When the humidity sensor 122 is in the reset state, it causes the mating contact 124 to separate from the connecting contact 123 to disconnect the circuit.
[0062] It should be noted that the connecting contact 123 can be fixed at a position on the housing 110, the humidity sensor 122 can be disposed on the housing 110 and spaced apart from the connecting contact 123, and the mating contact 124 can be disposed on the side of the humidity sensor 122 facing the connecting contact 123. Thus, when the humidity sensor 122 absorbs more water and extends, it can move the mating contact 124 toward the connecting contact 123 to make contact with the connecting contact 123 and thus conduct the circuit. When the humidity sensor 122 absorbs less water and returns to its original length, it can move the mating contact 124 away from the connecting contact 123 to separate from the connecting contact 123 and thus disconnect the circuit.
[0063] As an example, the humidity-controlled storage container 100 is used in conjunction with the refrigerator 1. The side of the shell 110 near the back of the cabinet 20 can be connected to a cold air duct to facilitate the formation of a low-temperature environment within the storage cavity 111. At this time, due to the temperature difference, the area within the shell 110 where condensation is likely to occur is correspondingly located on the side of the shell 110 near the cold air duct or evaporator. The shell 110 of this disclosure may have a top 113 along the Z direction, a bottom 114 spaced apart from the top 113 along the opposite direction of Z, and a side portion 115 connected between the top 113 and the bottom 114. The shell 110 also has a front side along the Y direction and a back side spaced apart from the front side along the opposite direction of Y. The shell 110 also has a left side along the X direction and a right side spaced apart from the left side along the opposite direction of X. When the shell 110 is installed in the refrigerator compartment of the refrigerator 1, the back side can be used to connect to the cold air duct. (See also...) Figure 1 To facilitate the installation of the humidity control component 120 while also ensuring effective dehumidification, the moisture permeation hole 112 and the humidity control component 120 can be installed on the top 113 of the housing 110 near the back. There may be one or more moisture permeation holes 112, and this disclosure does not impose any limitations. Of course, in other embodiments, the moisture permeation hole 112 and the humidity control component 120 can also be located at other positions on the housing 110, such as the side 115 or bottom 114 of the housing 110, and this disclosure does not impose any limitations.
[0064] Thus, the connecting contact 123 and the humidity sensor 122 can be respectively disposed on the side 115 of the housing 110, and the connecting contact 123 and the mating contact 124 are spaced apart along the Z direction. The connecting contact 123 and the mating contact 124 can be configured as conductive metal contacts, or non-metallic contacts such as graphite or conductive polymers; this disclosure does not impose any limitations. Furthermore, the connecting contact 123 and the mating contact 124 can be configured as a plug-in connection, which increases conductivity reliability and facilitates disassembly.
[0065] See Figure 3In some embodiments, to facilitate the connection or separation of the connecting contact 123 and the mating contact 124, the humidity sensor 122 includes a fixed portion 1221 connected to the housing 110 and a deformable portion 1222 connected to the fixed portion 1221 and spaced apart from the connecting contact 123. The mating contact 124 is disposed on the deformable portion 1222. As the amount of absorbed moisture increases, the deformable portion 1222 extends in the direction from the fixed portion 1221 toward the connecting contact 123, thereby causing the mating contact 124 to contact the connecting contact 123. As the amount of absorbed moisture decreases, the deformable portion 1222 returns to its original position in the direction from the connecting contact 123 toward the fixed portion 1221, thereby causing the mating contact 124 to separate from the connecting contact 123.
[0066] It should be noted that the fixing part 1221 can be fixedly connected to the housing 110, and can be fixed by means of adhesive, welding or screws, etc., which is not limited in this disclosure. The deformable part 1222 is connected between the fixing part 1221 and the mating contact 124. Since the fixing part 1221 of the humidity sensor 122 is already fixed to the housing 110, when the water absorption of the deformable part 1222 increases and it extends, the deformable part 1222 can extend in the direction indicated by Z, so as to drive the mating contact 124 to move towards the connecting contact 123, thereby conducting the circuit. When the water absorption of the deformable part 1222 decreases and it returns to its length, the deformable part 1222 can reset in the opposite direction of Z, so as to drive the mating contact 124 to move away from the connecting contact 123, thereby disconnecting the circuit.
[0067] Thus, by the mutual cooperation between the fixing part 1221 and the deformation part 1222 of the humidity sensor 122, the extension direction of the deformation part 1222 can be restricted, thereby driving the mating contact 124 to move relative to the connecting contact 123, so as to conduct or disconnect the connection circuit.
[0068] Furthermore, when the entire humidity sensor 122 is made of a humidity-sensitive material, both the fixing part 1221 and the deformation part 1222 can be made of a humidity-sensitive material. However, the fixing part 1221 needs to be fixedly installed with the housing 110 to prevent the deformation part 1222 from extending towards the fixing part 1221, thus allowing the deformation part 1222 to extend towards the contact point 123. Of course, the fixing part 1221 can also be made of a non-humidity-sensitive material, while the deformation part 1222 is made of a humidity-sensitive material. That is, the fixing part 1221 is not sensitive to humidity and moisture, and when the deformation part 1222 undergoes elongation deformation, the fixing part 1221 can also resist the elongation towards the fixing part 1221. This disclosure does not limit the material of the fixing part 1221.
[0069] In other embodiments, a support member may also be provided inside the housing 110 for mounting the humidity sensor 122, providing a larger mounting surface for the humidity sensor 122. The support member may be configured as a support column or a support platform, etc., and this disclosure does not impose any limitations. Of course, the positions of the connecting contact point 123 and the mating contact point 124 along the Z direction can also be interchanged, and this disclosure does not impose any limitations.
[0070] See Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a humidity-controlled storage container 100 according to one embodiment. Figure 2 for Figure 1 The cross-sectional view of the humidity-controlled storage container 100 shown at point AA (humidity sensor 122 is in the reset state). Figure 3 for Figure 2 The diagram shows the humidity sensor 122 in the open state. In some embodiments, to facilitate the preservation of fruits and vegetables in the storage cavity 111 and extend their storage time, the humidity sensor 122 can be configured to conduct the connection circuit within a humidity range of 80% to 95%, and the humidity range in which the humidity sensor 122 fully recovers its shape can be set to 20% to 60%.
[0071] Thus, when the content of fruits and vegetables in the storage cavity 111 is low, if the humidity range in the storage cavity 111 is between 20% and 60%, the storage cavity 111 is in a low humidity state, the humidity sensor 122 is in the reset state, the humidity sensor 122 does not extend, the dehumidifying fan 121 will not start, the moisture permeation hole 112 is closed, and the storage cavity 111 is kept moist to prevent the fruits and vegetables from wilting.
[0072] When the storage cavity 111 contains a large amount of fruits and vegetables, if the humidity range within the storage cavity 111 is between 80% and 95%, the storage cavity 111 is in a high-humidity state, and the humidity sensor 122 is in the open state. For example, when the humidity within the storage cavity 111 exceeds 80%, the humidity sensor 122 uses its extended deformation to connect the circuit with the dehumidifying fan 121, thereby activating the dehumidifying fan 121 to open the moisture permeation hole 112 and dehumidify the storage cavity 111 to prevent condensation.
[0073] When the humidity range within the storage cavity 111 is between 60% and 80%, if the humidity range increases from 60% to 80%, the humidity sensor 122 gradually extends. Although the humidity sensor 122 has an extended length, this extension is insufficient for the connecting contact point 123 to contact the mating contact point 124. Therefore, the circuit is not connected, and the dehumidifying fan 121 is also off. If the humidity range decreases from 80% to 60%, the humidity sensor 122 gradually recovers its length. At this time, the humidity sensor 122 has separated the connecting contact point 123 from the mating contact point 124, but the humidity sensor 122 has not fully recovered its length. Therefore, the mating contact point 124 still tends to move away from the connecting contact point 123, and the circuit is disconnected, and the dehumidifying fan 121 is also off.
[0074] In some embodiments, the extension length of the humidity sensor 122 is positively correlated with the humidity inside the storage cavity 111. In other words, as the humidity inside the storage cavity 111 increases, the extension deformation of the humidity sensor 122 also gradually increases. Thus, see... Figure 4 , Figure 4 This is a schematic diagram of a humidity-controlled storage container 100 with a pressure regulating component 125, as shown in one embodiment. The humidity control assembly 120 also includes a pressure regulating component 125, which is electrically connected between one of the mating contact 124 and the connecting contact 123 and the dehumidifying fan 121 to adjust the dehumidification speed of the dehumidifying fan 121 when the humidity sensor 122 is turned on.
[0075] It should be noted that the resistance value of the voltage regulator 125 connected to the circuit is negatively correlated with the extension length of the humidity sensor 122. When the humidity sensor 122 extends under high humidity conditions (e.g., humidity range of 80% to 95%), the resistance value of the voltage regulator 125 connected to the circuit decreases, thus increasing the dehumidification speed of the dehumidifying fan 121 and increasing the dehumidification efficiency in the storage cavity 111 to prevent condensation. When the humidity sensor 122 returns to its original length under low humidity conditions (e.g., humidity range of 20% to 60%), the resistance value of the voltage regulator 125 connected to the circuit increases, thus decreasing the dehumidification speed of the dehumidifying fan 121 and reducing the dehumidification efficiency in the storage cavity 111 to retain moisture and prevent food from wilting. Thus, by changing the length of the humidity sensor 122, the resistance of the voltage regulator 125 connected to the circuit can be adjusted, thereby adjusting the dehumidification speed of the dehumidifier 121. The dehumidification speed of the dehumidifier 121 is positively correlated with the extension length of the humidity sensor 122.
[0076] See Figure 4As an example, the voltage regulator 125 includes a sliding rheostat. The fixed terminal 1251 of the sliding rheostat is electrically connected to the dehumidifying fan 121, and the sliding terminal 1252 of the sliding rheostat is electrically connected to the mating contact 124. When the humidity sensor 122 is in the open state, the sliding terminal 1252 moves toward the fixed terminal 1251 to decrease the resistance of the sliding rheostat. When the humidity sensor 122 is in the reset state, the sliding terminal 1252 moves away from the fixed terminal 1251 to increase the resistance of the sliding rheostat.
[0077] When the humidity inside the storage cavity 111 reaches 80%, the extension of the humidity sensor 122 can drive the mating contact 124 to contact the connecting contact 123, thereby connecting the circuit. At this time, the sliding terminal 1252 can be located at the end away from the fixed terminal 1251 (for example, the fixed terminal 1251 is located at the top of the sliding rheostat along the Z direction, and the sliding terminal 1252 can be located at the bottom of the sliding rheostat, which is spaced apart from the top along the Z direction). In this case, the resistance of the sliding rheostat connected to the circuit is R1, and the dehumidification speed of the dehumidifying fan 121 is r1. When the humidity inside the storage cavity 111 reaches 95%, the humidity sensor 122 can absorb water and fully extend, thereby pushing the sliding terminal 1252 closer to the fixed terminal 1251. In this case, the resistance of the sliding rheostat connected to the circuit is R2, and the dehumidification speed of the dehumidifying fan 121 is r2. As the distance between the sliding terminal 1252 and the fixed terminal 1251 decreases, R2 becomes less than R1. The dehumidifying fan 121 obtains a larger voltage drop when the resistance of the sliding rheostat is R2, making r2 greater than r1. Consequently, the dehumidifying fan 121 obtains a larger dehumidification speed, which can improve dehumidification efficiency, accelerate the discharge of moisture, and further reduce condensation under high humidity conditions.
[0078] Conversely, when the humidity inside the storage cavity 111 decreases from 95% to 80%, the resistance of the sliding rheostat increases, and the rotation speed of the dehumidifying fan 121 gradually decreases. When the humidity inside the storage cavity 111 is less than 80%, the two contacts separate, and the dehumidifying fan 121 can stop rotating, thereby stopping the exhaust of moisture, keeping the storage cavity 111 moist, and preventing the food from wilting.
[0079] See Figure 5 , Figure 5 This is a schematic diagram of the structure of a humidity-controlled storage container 100 with a pressure regulating member 125, as shown in another embodiment. In some embodiments, the sliding terminal 1252 of the sliding rheostat can also be electrically connected to the connecting contact 123. The connecting contact 123 is slidably connected to the housing 110. When the humidity sensor 122 is in the open state, it pushes the mating contact 124 to contact the connecting contact 123 and pushes the connecting contact 123 to slide relative to the housing 110, thereby causing the sliding terminal 1252 to move relative to the fixed terminal 1251.
[0080] It should be noted that when the sliding terminal 1252 of the sliding rheostat is connected to the connecting contact 123, the connecting contact 123 can slide relative to the housing 110, thereby adjusting the position of the sliding terminal 1252 relative to the fixed terminal 1251 and adjusting the resistance value of the sliding rheostat connected to the circuit. The sliding connection between the connecting contact 123 and the housing 110 can be achieved by installing a guide rail or setting a sliding groove, etc., and this disclosure does not impose any limitations.
[0081] Thus, when the humidity inside the storage cavity 111 increases, the humidity sensor 122 absorbs more water and extends its length, causing the mating contact 124 to contact the connecting contact 123 to conduct the circuit. As the humidity inside the storage cavity 111 further increases, the extension length of the humidity sensor 122 also continues to increase, which can push the mating contact 124 to continue moving in the direction indicated by Z, thereby causing the connecting contact 123 to slide along the housing 110, so that the sliding terminal 1252 also moves relative to the fixed terminal 1251, thereby adjusting the resistance value.
[0082] See Figure 6 , Figure 6 This is a schematic diagram of the linkage between a dehumidifying fan 121 and a cooling fan 140 as shown in one embodiment. In some embodiments, in order to maintain a low-temperature environment in the storage cavity 111 and prevent condensation, the housing 110 is also provided with a cold air hole 116 communicating with the storage cavity 111. The humidity-controlled storage container 100 also includes a controller 130 electrically connected to the dehumidifying fan 121 and a cooling fan 140 electrically connected to the controller 130. The cooling fan 140 blows cold air into the storage cavity 111 through the cold air hole 116. The controller 130 adjusts the cooling speed of the cooling fan 140 according to the dehumidification speed of the dehumidifying fan 121, and the dehumidification speed of the dehumidifying fan 121 is negatively correlated with the cooling speed of the cooling fan 140.
[0083] It should be noted that when the humidity-controlled storage container 100 is applied to the refrigerator 1, the refrigeration fan 140 can be connected to the refrigeration duct of the refrigerator 1 to blow the cold air in the refrigeration duct into the storage cavity 111 through the cold air hole 116 (cold air such as...). Figure 6 (The arrow indicates that the contents enter the storage cavity 111), forming a refrigerated environment within the storage cavity 111 to meet the low-temperature storage requirements of food.
[0084] Meanwhile, based on the condensation formation conditions within the storage cavity 111, it is known that when the storage cavity 111 is refrigerated, the low temperature of the cold air blowing onto the inner wall of the casing 110 will increase the temperature difference between the storage cavity 111 and the inner wall. Therefore, when the storage cavity 111 is in a high-humidity state, moisture easily condenses on the inner wall of the storage cavity 111. Accordingly, if the temperature difference within the storage cavity 111 can be appropriately reduced when it is in a high-humidity state, the condensation phenomenon can be improved.
[0085] Thus, the refrigeration fan 140 and the dehumidification fan 121 of this disclosure can be electrically connected via a controller 130 to coordinate the interaction between the refrigeration fan 140 and the dehumidification fan 121. Specifically, when the storage cavity 111 is in a high-humidity state, the elongation of the humidity sensor 122 increases, and the dehumidification speed of the dehumidification fan 121 increases to discharge excess moisture from the storage cavity 111 through the moisture permeation hole 112 (moisture such as...). Figure 6 (The air is discharged into the storage cavity 111 in the direction indicated by the arrow). The controller 130, by detecting that the dehumidifying fan 121 has a high dehumidification speed, can further presume that the humidity inside the storage cavity 111 is high. Therefore, the controller 130 can adjust and reduce or turn off the cooling fan 140 to reduce the amount of cold air entering the storage cavity 111, reduce the temperature difference, and improve the condensation effect. Correspondingly, when the storage cavity 111 is in a low-humidity state, the extension of the humidity sensor 122 recovers, the dehumidification speed of the dehumidifying fan 121 decreases or stops, and the controller 130, by detecting that the dehumidifying fan 121 has a low dehumidification speed, can further presume that the humidity inside the storage cavity 111 is low. Therefore, the controller 130 can adjust and start the cooling fan 140 to restore cooling and maintain the low-temperature environment inside the storage cavity 111.
[0086] It should also be noted that a speed limit can be pre-input into the controller 130 for comparison with the dehumidification speed of the cooling fan 140. When the dehumidification speed exceeds the speed limit, the storage cavity 111 is in a high-humidity state, and the controller 130 reduces or shuts down the cooling fan 140. When the dehumidification speed does not exceed the speed limit, the controller 130 can restore the cooling fan 140 to normal cooling to maintain the low-temperature environment in the storage cavity 111. This disclosure does not limit the specific value of the speed limit.
[0087] See Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the humidity sensor 122 in a reset state according to another embodiment. Figure 8 for Figure 7 The diagram shows the structure of the humidity sensor 122 in the open state. In one embodiment, the deformable part 1222 softens as the amount of water absorbed increases, and the deformable part 1222 is driven by gravity to move the mating contact 124 toward the connecting contact 123 and make contact; the deformable part 1222 resets as the amount of water absorbed decreases, thereby causing the mating contact 124 to separate from the connecting contact 123.
[0088] It should be noted that when the deformable part 1222 and the fixed part 1221 are arranged in the direction indicated by Z in the figure, the deformable part 1222 is above the fixed part 1221. After absorbing water, the deformable part 1222 softens, and its gravity increases. Under the influence of gravity, the deformable part 1222 bends towards the fixed part 1221. Thus, by placing the connecting contact point 123 at the point where the deformable part 1222 bends, the deformable part 1222 can drive the mating contact point 124 to contact the connecting contact point 123 during the bending process, thereby conducting the circuit. Correspondingly, after the deformable part 1222 loses water, it becomes lighter and can spring back to its original position, thereby disconnecting the circuit. As an example, the deformable part 1222 can be made of materials such as sponge, hydrogel, or rubber, and this disclosure does not impose any limitations.
[0089] In other embodiments, the fixing part 1221 and the deformable part 1222 can be arranged along the direction indicated by Y in the figure, with the deformable part 1222 located to the right of the fixing part 1221. The deformable part 1222 is made of a hydrophilic material, and the fixing part 1221 is made of a hydrophobic material. When the deformable part 1222 absorbs water, it expands and elongates, while the length of one side of the fixing part 1221 remains unchanged. This causes the deformable part 1222 to bend towards the fixing part 1221 after elongation, thereby bringing the connecting contact point 123 into contact with the mating contact point 124 to conduct the circuit. When the deformable part 1222 loses water, it returns to its original position away from the fixing part 1221, disconnecting the circuit. This disclosure is not limiting.
[0090] See Figure 9 , Figure 9 This is a flowchart illustrating a humidity control method using a humidity-controlled storage container 100 according to one embodiment. This disclosure also provides a humidity control method implemented using the humidity-controlled storage container 100 in any of the above embodiments, comprising the following steps:
[0091] The humidity sensor 122 switches between open and reset states based on the humidity changes in the storage cavity 111.
[0092] When the humidity in the storage cavity 111 increases, the humidity sensor 122 absorbs more moisture and extends its length. The humidity sensor 122 is in the open state to conduct the connection circuit with the dehumidifying fan 121. The dehumidifying fan 121 is started to discharge the moisture in the storage cavity 111 through the moisture permeation hole 112 to reduce the humidity in the storage cavity 111.
[0093] When the humidity in the storage cavity 111 decreases, the humidity sensor 122 absorbs less water and gradually recovers its deformation. The humidity sensor 122 is in a reset state to disconnect the connection circuit with the dehumidifier 121. The dehumidifier 121 is turned off, and the moisture in the storage cavity 111 is not discharged through the moisture vent 112 to keep the storage cavity 111 moisturized.
[0094] It should be noted that the humidity within storage compartment 111 can be adjusted by the amount of fruits and vegetables present. When the amount of fruits and vegetables in storage compartment 111 increases, the humidity within storage compartment 111 increases. When the amount of fruits and vegetables in storage compartment 111 decreases, the humidity within storage compartment 111 decreases.
[0095] Thus, when the storage cavity 111 contains a large quantity of fruits and vegetables, the strong transpiration of the fruits and vegetables increases the humidity inside the storage cavity 111. In this high-humidity environment, the humidity sensor 122 extends, connecting the contact point 123 to the mating contact point 124, thus activating the circuit connecting to the dehumidifying fan 121. This drives the dehumidifying fan 121 to start operating, thereby opening the vent hole 112 to expel moisture from the storage cavity 111, preventing excess moisture from condensing on the walls of the storage cavity 111. Simultaneously, the moisture expelled through the vent hole 112 also reduces the humidity inside the storage cavity 111, facilitating the evaporation of moisture from the surface of the fruits and vegetables and preventing the growth of bacteria and mold, which could lead to rotting. When the amount of fruits and vegetables stored in the storage cavity 111 is small, the transpiration of the fruits and vegetables is weak, and the humidity in the storage cavity 111 decreases. The humidity sensor 122 recovers its deformation in the low humidity environment, and the contact point 123 separates from the mating contact point 124, disconnecting the connection circuit between the dehumidifying fan 121 and turning off the dehumidifying fan 121. This closes the moisture vent 112, preventing the moisture in the storage cavity 111 from being discharged through the moisture vent 112, thus keeping the storage cavity 111 moist and preventing the fruits and vegetables from drying out and wilting due to the decrease in humidity.
[0096] See Figure 10 and Figure 11 , Figure 10 This is a flowchart illustrating the resistance change of the pressure regulating component 125 in a humidity control method according to one embodiment. Figure 11 This is a schematic diagram showing the relationship between the rotation speed of the dehumidifying fan 121 and the humidity change in the storage cavity 111 in a humidity control method according to one embodiment. In some embodiments, to more flexibly adjust the humidity in the storage cavity 111, the humidity control component 120 further includes a pressure regulating component 125.
[0097] During the process of the humidity sensor 122 being in the open state, the following steps are also included: the humidity sensor 122 gradually extends as the humidity in the storage cavity 111 increases. The humidity sensor 122 drives the voltage regulator 125 to operate, thereby reducing the resistance of the voltage regulator 125 connected to the circuit, so as to increase the dehumidification speed of the dehumidifying fan 121.
[0098] During the process of the humidity sensor 122 being in the reset state, the following steps are also included: the humidity sensor 122 gradually recovers its deformation as the humidity in the storage cavity 111 decreases. The humidity sensor 122 drives the voltage regulator 125 to operate, increasing the resistance of the voltage regulator 125 connected to the circuit, thereby reducing the dehumidification speed of the dehumidifying fan 121.
[0099] It should be noted that the resistance value of the voltage regulator 125 connected to the circuit is negatively correlated with the extension length of the humidity sensor 122. When the humidity sensor 122 extends under high humidity conditions (e.g., humidity range of 80% to 95%), the resistance value of the voltage regulator 125 connected to the circuit decreases, thus increasing the dehumidification speed of the dehumidifying fan 121 and increasing the dehumidification efficiency in the storage cavity 111 to prevent condensation. When the humidity sensor 122 returns to its original length under low humidity conditions (e.g., humidity range of 20% to 60%), the resistance value of the voltage regulator 125 connected to the circuit increases, thus decreasing the dehumidification speed of the dehumidifying fan 121 and reducing the dehumidification efficiency in the storage cavity 111 to retain moisture and prevent food from wilting. Thus, by changing the length of the humidity sensor 122, the resistance of the voltage regulator 125 connected to the circuit can be adjusted, thereby adjusting the dehumidification speed of the dehumidifier 121. The dehumidification speed of the dehumidifier 121 is positively correlated with the extension length of the humidity sensor 122.
[0100] like Figure 11 As shown, solid lines represent the dehumidification speed of the dehumidifying fan 121, and dashed lines represent the humidity changes within the storage cavity 111. Figure 11 The points where the dashed line intersects the vertical axis represent the placement of fruits and vegetables. As the fruits and vegetables transpire, the humidity inside the storage cavity 111 gradually increases, and the dashed line shows an upward trend. Simultaneously, the humidity sensor 122 extends in length as the humidity increases, thereby activating the dehumidifier fan 121. The dehumidification speed of the dehumidifier fan 121 is positively correlated with the humidity inside the storage cavity 111. When the humidity inside the storage cavity 111 increases, the dehumidification speed of the dehumidifier fan 121 increases; when the humidity inside the storage cavity 111 decreases, the dehumidification speed of the dehumidifier fan 121 decreases. Therefore, the humidity curve inside the storage cavity 111 exhibits an adaptive, fluctuating pattern, and the fluctuation range can be maintained between 80% and 95% to maintain the humidity requirements for storing fruits and vegetables, while also expelling excess moisture from the storage cavity 111 to reduce condensation.
[0101] in, Figure 11 The degree of inclination of the solid and dashed lines can be affected by the deformation length and speed of the humidity sensor 122 or the resistance change of the voltage regulator 125.
[0102] See Figures 12 to 14 , Figure 12 This is a schematic diagram showing the electrical connection between the controller 130 and the dehumidifying fan 121 and the refrigeration fan 140 in a humidity control method according to one embodiment. Figure 13 This is a flowchart illustrating the relationship between the rotational speed of the dehumidifying fan 121 and the rotational speed of the refrigeration fan 140 in a humidity control method according to one embodiment. Figure 14 for Figure 13The diagram illustrates the relationship between the rotational speed of the dehumidifying fan 121 and the rotational speed of the refrigeration fan 140 in the humidity control method shown. In some embodiments, to maintain a low-temperature environment within the storage cavity 111 while preventing condensation, the humidity-controlled storage container 100 further includes a controller 130 and a refrigeration fan 140, and the humidity control method further includes the following steps:
[0103] The speed limit of the dehumidifying fan 121 is preset in the controller 130.
[0104] The dehumidification speed of the dehumidification fan 121 is obtained using the controller 130, and it is determined whether the dehumidification speed exceeds the speed limit.
[0105] If the dehumidification speed of the dehumidification fan 121 does not exceed the speed limit, the controller 130 drives the refrigeration fan 140 to start and blow cold air into the storage cavity 111 for cooling.
[0106] If the dehumidification speed of the dehumidification fan 121 exceeds the speed limit, the controller 130 will shut down the refrigeration fan 140 or reduce the refrigeration speed of the refrigeration fan 140, thereby stopping or reducing the blowing of cold air into the storage cavity 111.
[0107] It should be noted that when the humidity-controlled storage container 100 is applied to the refrigerator 1, the refrigeration fan 140 can be connected to the refrigeration duct of the refrigerator 1 to blow the cold air in the refrigeration duct through the cold air hole 116 into the storage cavity 111, forming a refrigeration environment in the storage cavity 111 to meet the low-temperature storage requirements of food.
[0108] Meanwhile, to appropriately reduce the temperature difference within the storage cavity 111 when it is in a high-humidity state and improve condensation, the controller 130 can adjust the cooling speed of the refrigeration fan 140 according to the dehumidification speed of the dehumidification fan 121. The controller 130 can pre-input a speed limit value for comparison with the dehumidification speed of the refrigeration fan 140. When the dehumidification speed exceeds the speed limit value, the storage cavity 111 is in a high-humidity state, and the controller 130 reduces or shuts down the refrigeration fan 140 to reduce the amount of cold air entering the storage cavity 111, narrowing the temperature difference and improving condensation. When the dehumidification speed does not exceed the speed limit value, the controller 130 can restore the refrigeration fan 140 to normal cooling to maintain a low-temperature environment within the storage cavity 111. This disclosure does not limit the specific value of the speed limit value.
[0109] like Figure 14 As shown, solid lines represent the dehumidification speed of dehumidifier 121, thin dashed lines represent humidity changes in storage cavity 111, and thick dashed lines represent cooling speed of refrigeration fan 140. Figure 14The points where the thin dashed line intersects the vertical axis represent the placement of fruits and vegetables. As the fruits and vegetables transpire, the humidity inside the storage cavity 111 gradually increases, and the thin dashed line shows an upward trend. Simultaneously, the humidity sensor 122 extends in length as the humidity increases, thereby activating the dehumidifier fan 121. The dehumidification speed of the dehumidifier fan 121 is positively correlated with the humidity inside the storage cavity 111, while the cooling speed of the refrigeration fan 140 is negatively correlated with the dehumidification speed of the dehumidifier fan 121. When the humidity inside the storage cavity 111 increases, the dehumidification speed of the dehumidifier fan 121 increases, and the cooling speed of the refrigeration fan 140 decreases. When the humidity inside the storage cavity 111 decreases, the dehumidification speed of the dehumidifier fan 121 decreases, and the refrigeration fan 140 resumes cooling. Therefore, the humidity curve inside the storage cavity 111 exhibits an adaptive, fluctuating pattern, and the fluctuation range can be maintained between 80% and 95% to maintain the humidity and low-temperature requirements for fruit and vegetable storage. Furthermore, the dehumidifier 121 can also expel excess moisture from the storage cavity 111 to reduce condensation.
[0110] in, Figure 14 The degree of inclination of solid lines, thin dashed lines and thick dashed lines can be affected by the deformation length speed of humidity sensor 122 or the resistance change of voltage regulator 125.
[0111] See Figure 15 and Figure 16 , Figure 15 This is a schematic diagram of the structure of refrigerator 1 according to one embodiment. Figure 16 for Figure 15 The refrigerator 1 shown is a cross-sectional view at point BB. This disclosure also provides a refrigerator 1, including a cabinet 20 and a humidity-controlled storage container 100 of any of the above embodiments. The cabinet 20 has a refrigerator compartment, and a housing 110 is disposed within the refrigerator compartment. The housing 110 is reciprocating relative to the cabinet 20 to open or close the storage cavity 111.
[0112] It should be noted that the cabinet 20 is equipped with a refrigerator compartment 21, and the refrigerator 1 also includes a door 10 for opening or closing the refrigerator compartment 21. The shell 110 can be configured as a drawer shape, and the shell 110 and the inner wall of the refrigerator compartment can be configured as a sliding connection (such as connecting a guide device such as a slide rail or groove) so that the shell 110 can move back and forth relative to the cabinet 20, thereby opening or closing the storage cavity 111, making it convenient for users to store or take out fruits and vegetables.
[0113] In some embodiments, the refrigerator 1 further includes a compressor, a condenser, an evaporator, and a throttling device (not shown). The cabinet 20 also includes a freezer compartment 22, and the refrigerator 1 further includes a door 10 for opening or closing the freezer compartment 22. The compressor, condenser, evaporator, and throttling device are respectively disposed in the cabinet 20, and at least a portion of the evaporator is disposed within the freezer compartment 22.
[0114] When refrigerator 1 is running, the compressor outputs high-temperature, high-pressure gaseous refrigerant, which is then blown into the condenser. The condenser condenses the high-temperature, high-pressure gaseous refrigerant into medium-temperature, high-pressure refrigerant. This medium-temperature, high-pressure refrigerant then undergoes expansion and throttling through the throttling device, further reducing its pressure and temperature. The low-temperature, low-pressure liquid refrigerant flows out from the throttling device to the evaporator. The low-temperature, low-pressure liquid refrigerant evaporates into gaseous refrigerant within the evaporator. Since at least a portion of the evaporator is located within the freezer compartment 22, the refrigerant absorbs a large amount of heat from the freezer compartment 22 during evaporation, thereby lowering the temperature within the freezer compartment 22 and facilitating the freezing of items, thus achieving the cooling function of refrigerator 1. The refrigerant exiting the evaporator replenishes the compressor, forming a refrigerant circuit. In this way, the refrigerant continuously circulates in the refrigerant circuit to maintain the freezing environment of the freezer compartment 22 (e.g., below -1°C).
[0115] In some embodiments, a refrigeration duct is provided between the refrigerated compartment 21 and the frozen compartment 22 to facilitate the blowing of some of the cold air from the frozen compartment 22 into the refrigerated compartment 21, thereby reducing or maintaining the low-temperature environment (e.g., 2°C to 8°C) of the refrigerated compartment 21. The shell 110 of the humidity-controlled storage container 100 can be disposed within the refrigerated compartment 21 to form a low-temperature environment within the storage cavity 111. Simultaneously, when the humidity-controlled storage container is equipped with a refrigeration fan 140, the refrigeration fan 140 can be disposed within the refrigeration duct to blow cold air from the refrigeration duct through the cold air hole 116 into the storage cavity 111, thereby forming a low-temperature environment within the storage cavity 111.
[0116] Therefore, when the humidity-controlled storage container 100 is used in the refrigerator 1, the storage cavity 111 can maintain a low-temperature environment while also adaptively adjusting the humidity inside the storage cavity 111 according to the amount of fruits and vegetables stored therein. This allows for humidification of the storage cavity 111 under low humidity conditions, extending the storage time of the food inside. Simultaneously, the humidity-controlled storage container 100 provided in this disclosure can also expel excess moisture from the storage cavity 111 under high humidity conditions through adaptive humidity control, reducing condensation and thus improving the user experience.
[0117] Other structural details regarding refrigerator 1 are not described in this disclosure.
[0118] The technical solutions or features described in the above embodiments can be combined or complemented by each other without conflict. The scope of this disclosure is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings. All modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
