Current refrigerators typically achieve cooling by forming a refrigeration circuit consisting of a compressor, condenser, capillary tube, and evaporator connected by pipes carrying refrigerant. However, the adjustable temperature range of current refrigerator compartments is relatively small, which cannot meet the growing demands of users. Utility Model Content

[0010] According to the storage device of this application, a heating component provides heat to the variable-temperature chamber to achieve wide temperature range adjustment. This not only realizes the refrigeration and preservation functions of related technologies but also meets the needs for heating items (such as heating leftovers or warming baby formula), enhancing the functionality of the storage device and broadening its application range. Simultaneously, considering that the temperature increase inside the variable-temperature chamber during heating leads to an increase in internal air pressure, a pressure relief component promptly releases excess gas inside the variable-temperature chamber to balance the air pressure inside and outside, reducing the possibility of deformation of the variable-temperature door and cabinet, and improving the reliability of the storage device.

[0028] A sensor switch, communicatively connected to the heating assembly, is used to sense the opening and closing state of the variable temperature door; wherein, when the sensor switch senses that the variable temperature door is in the open state, the heating assembly does not operate.

[0029] According to one embodiment of this application, it also includes:

[0030] A temperature sensing module is installed in the variable temperature chamber and is communicatively connected to the heating component and the pressure relief component, respectively, for obtaining the temperature signal of the variable temperature chamber;

[0052] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0053] The following is for reference. Figures 1-2 The storage device provided in the embodiments of this application is described. The storage device includes a housing 100, a temperature-controlled door 210, a heating component 300, and a pressure relief component 400.

[0054] It should be noted that the storage device in this embodiment can be understood as a broad category of refrigeration and storage device, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. Storage devices have diverse structural forms and a wide range of applications. This embodiment uses a vertical refrigerator as an example for description.

[0055] The enclosure 100 forms a variable temperature chamber 110; a variable temperature door 210 is installed on the enclosure 100 in an openable and closable manner to seal the variable temperature chamber 110. It should be noted that the shape and size of the variable temperature chamber 110 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0056] Understandably, when the variable-temperature door 210 is closed, it effectively isolates the variable-temperature chamber 110 from the outside environment, ensuring the stability and consistency of the temperature within the variable-temperature chamber 110, extending the heat preservation time of items stored in the variable-temperature chamber 110, and ensuring more precise and reliable temperature regulation within the variable-temperature chamber 110. It should be noted that the variable-temperature door 210 can be a rotating door pivotally connected to the housing 100, or a drawer-type door slidingly mounted on the housing 100; this embodiment does not impose specific limitations on either.

[0057] A heating component 300 is disposed in the housing 100 for providing heat to the variable temperature chamber 110; a pressure relief component 400 is disposed in the housing 100; wherein,

[0058] When the variable temperature chamber 110 is closed by the variable temperature door 210, the pressure relief assembly 400 is adapted to connect or disconnect the variable temperature chamber 110 from the outside.

[0059] Understandably, using the heating component 300 to provide heat to the variable temperature chamber 110 enables the adjustment of its wide temperature range. This not only achieves the refrigeration and preservation functions of related technologies but also meets the needs for heating items (such as heating leftovers or warming baby formula), enhancing the functionality of the storage equipment and broadening its application scope. Simultaneously, considering that the temperature increase within the variable temperature chamber 110 during heating leads to increased internal pressure, the pressure relief component 400 promptly releases excess gas within the chamber to balance the pressure inside and outside, reducing the possibility of deformation of the variable temperature door 210 and the cabinet 100, thus improving the reliability of the storage equipment.

[0060] The storage device provided according to the embodiments of this application can achieve a wide temperature range adjustment, which improves the functionality and reliability of the storage device and broadens its application scope.

[0061] In some embodiments, such as Figure 2 As shown, the enclosure 100 includes an outer shell, a temperature-controlled inner liner 101, and an insulation layer. A temperature-controlled door 210 is closable and mounted on the outer shell. The temperature-controlled inner liner 101 is installed inside the outer shell to form a temperature-controlled chamber 110, and the inner liner 101 is made of metal. The insulation layer is disposed between the outer shell and the inner liner 101. For example, the inner liner 101 is made of stainless steel. The insulation layer may be made of materials including, but not limited to, foam.

[0062] Understandably, metal materials possess excellent thermal conductivity and mechanical strength, enabling them to quickly transfer heat to all parts of the variable-temperature chamber 110, improving cooling and heating efficiency and temperature uniformity within the chamber. Furthermore, they can withstand significant pressure and temperature variations, reducing the likelihood of deformation of the inner liner 101. The outer shell provides physical protection for the storage equipment, while the insulation layer, positioned between the outer shell and the inner liner 101, effectively reduces heat transfer, minimizes energy loss, and enhances temperature stability within the variable-temperature chamber 110.

[0063] In some embodiments, such as Figure 2 As shown, the pressure relief assembly 400 includes a pressure relief pipe and a pressure relief valve 410. The pressure relief pipe is disposed in the housing 100 and forms a pressure relief channel. The first end of the pressure relief channel is connected to the temperature-controlled chamber 110, and the second end of the pressure relief channel is connected to the outside. The pressure relief valve 410 is disposed inside the pressure relief pipe and is used to open or close the pressure relief channel. It should be noted that the size and shape of the pressure relief channel and the specific structure of the pressure relief valve 410 can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0064] Understandably, the pressure relief pipe, as a channel connecting the variable temperature chamber 110 to the outside, provides a physical path for gas flow. When pressure relief is needed, the variable temperature door 210 does not need to be opened; only the pressure relief valve 410 needs to be opened. The gas inside the variable temperature chamber 110 enters the pressure relief channel through the first end and is smoothly discharged to the outside through the second end. At the same time, outside air is allowed to enter the variable temperature chamber 110 through the pressure relief channel when necessary, thereby achieving a balance between internal and external pressures and reducing the amount of cold energy leaked when the variable temperature chamber 110 is connected to the outside, thus improving energy utilization. Simultaneously, the pressure relief valve 410, located within the pressure relief channel, can also close the pressure relief channel, reducing the possibility of dust and other impurities entering the variable temperature chamber 110.

[0065] It should be noted that the pressure relief pipe can also be integrally formed with the housing 100 to reduce processing steps. This embodiment does not impose specific restrictions on this.

[0066] In some embodiments, such as Figure 2 As shown, the pressure relief assembly 400 is located near the top of the temperature-controlled chamber 110.

[0067] Understandably, the upward movement of hot air accelerates the discharge of hot air from the variable temperature chamber 110 to the outside, minimizing energy consumption, reducing the possibility of condensate forming near the pressure relief channel, and extending the service life of the pressure relief component 400.

[0068] In some embodiments, such as Figure 2As shown, the openings of the pressure relief channel and the temperature-controlled chamber 110 are positioned opposite each other to form a more direct gas flow path, reducing gas flow resistance during pressure relief and improving pressure relief efficiency. Simultaneously, the first end of the pressure relief channel is far from the opening of the temperature-controlled chamber 110, which also reduces the possibility of items shifting or being damaged due to airflow impact during pressure relief, improving the convenience and aesthetics of retrieving items within the temperature-controlled chamber 110 and enhancing the user experience. For example, the opening of the temperature-controlled chamber 110 faces forward, and the pressure relief assembly 400 is located at the rear of the temperature-controlled chamber 110.

[0069] In some embodiments, such as Figure 2 As shown, the pressure relief assembly 400 also includes a filter element 420, which is disposed in the pressure relief channel. The filter element 420 includes, but is not limited to, an air filter, an activated carbon filter, an electrostatic filter, or a photocatalytic filter.

[0070] It is understandable that by installing a filter element 420 in the pressure relief channel, when the variable temperature chamber 110 is connected to the outside world through the pressure relief channel, it can effectively filter out impurities such as dust, particulate matter or pollen and odors from the outside world from entering the variable temperature chamber 110, thereby improving the reliability and safety of the variable temperature chamber 110.

[0071] In some embodiments, such as Figure 2 As shown, both the first and second ends of the pressure relief channel are equipped with filter elements 420 to further improve the filtration effect. Of course, in other embodiments, filter elements 420 may be provided only at the first or second end of the pressure relief channel; this embodiment does not impose specific limitations on this.

[0072] In some embodiments, such as Figure 2 As shown, the heating assembly 300 includes a first heating element 310 and a second heating element 320 that are independent of each other. Both the first heating element 310 and the second heating element 320 are disposed in the housing 100, and the wall surface where the first heating element 310 is located is different from the wall surface where the second heating element 320 is located. Exemplarily, the first heating element 310 and the second heating element 320 include, but are not limited to, heating wires.

[0073] Understandably, the first heating element 310 and the second heating element 320 are respectively installed on different wall surfaces, enabling them to provide heat to the variable temperature chamber 110 from multiple directions. This multi-point heating method can improve the heating temperature range and efficiency, as well as the uniformity of heat distribution, and optimize the internal space layout of the cabinet 100. Furthermore, the independent first heating element 310 and the second heating element 320 can be adjusted to operate independently according to different needs, achieving precise temperature control and increasing the redundancy of the storage equipment.

[0074] In some embodiments, such as Figure 2 As shown, both the first heating element 310 and the second heating element 320 are located outside the temperature-changing chamber 110, that is, on the outer wall surface of the temperature-changing inner liner 101. Of course, in other embodiments, at least one of the first heating element 310 and the second heating element 320 may be located inside the temperature-changing chamber 110, and this embodiment does not impose any specific restrictions on this.

[0075] In some embodiments, such as Figure 2 As shown, the first heating element 310 is positioned away from the opening of the variable temperature chamber 110, which can improve heat utilization efficiency, reduce energy waste, and facilitate users to pick up and put down items.

[0076] In some embodiments, such as Figure 2 As shown, there are two second heating elements 320, which are arranged opposite each other to further increase heating efficiency and heating uniformity, and optimize heat distribution.

[0077] In some embodiments, such as Figure 2 As shown, two second heating elements 320 are respectively disposed at the top and bottom of the temperature-changing chamber 110. That is, the second heating element 320 located at the top can quickly raise the temperature at the top of the temperature-changing chamber 110, and the second heating element 320 located at the bottom can ensure that the temperature at the bottom of the temperature-changing chamber 110 keeps up in time, so as to reduce the phenomenon of uneven heating and cooling.

[0078] In some embodiments, such as Figure 2 As shown, the variable temperature chamber 110 has a heating mode; in the heating mode, both the first heating element 310 and the second heating element 320 are working, and the variable temperature chamber 110 is selectively connected to the outside world through the pressure relief assembly 400.

[0079] Understandably, in heating mode, both the first heating element 310 and the second heating element 320 are working, which can quickly and evenly increase the temperature inside the variable temperature chamber 110. At the same time, the pressure relief valve 410 can be selectively opened to quickly balance the air pressure inside and outside the variable temperature chamber 110 in heating mode, thereby improving the reliability of the storage equipment operation.

[0080] In some embodiments, such as Figure 2 As shown, the variable temperature chamber 110 also has a refrigeration mode; in the refrigeration mode, one of the first heating element 310 and the second heating element 320 is working, and the variable temperature chamber 110 is always disconnected from the outside through the pressure relief assembly 400.

[0081] Understandably, by operating only one of the first heating element 310 and the second heating element 320, the temperature within the variable temperature compartment 110 is maintained within the range required for refrigeration. Simultaneously, in refrigeration mode, the pressure relief valve 410 is normally closed, meaning the variable temperature compartment 110 is always disconnected from the outside environment via the pressure relief assembly 400. This effectively maintains the airtightness of the variable temperature compartment 110 when the variable temperature door 210 is closed, reducing energy loss and improving refrigeration efficiency.

[0082] In some embodiments, such as Figure 2 As shown, the variable temperature chamber 110 also has a freezing mode; in the freezing mode, neither the first heating element 310 nor the second heating element 320 works, and the variable temperature chamber 110 is always disconnected from the outside world through the pressure relief component 400.

[0083] Understandably, by disabling both the first heating element 310 and the second heating element 320, the temperature of the variable temperature chamber 110 can be rapidly reduced to the range required for freezing via the refrigeration system. Simultaneously, in freezing mode, the pressure relief valve 410 is normally closed, meaning the variable temperature chamber 110 is always disconnected from the outside environment via the pressure relief assembly 400. This effectively maintains the airtightness of the variable temperature chamber 110 when the variable temperature door 210 is closed, reducing energy loss and improving freezing efficiency.

[0084] In some embodiments, such as Figure 2 As shown, the storage device also includes a variable-temperature evaporator 730, a condenser, and a compressor 710. The variable-temperature evaporator 730 is located in the housing 100 and near the variable-temperature chamber 110, and is used to provide cooling capacity to the variable-temperature chamber 110. The condenser is located in the housing 100 and near the variable-temperature chamber 110, and is used for heat exchange with the variable-temperature evaporator 730. The compressor 710 is located in the housing 100, and the compressor 710, condenser, and variable-temperature evaporator 730 are connected sequentially. The type of condenser includes, but is not limited to, a side-plate condenser, a microchannel condenser, or a wire tube condenser.

[0085] Understandably, the refrigeration system includes a compressor 710, a condenser, and a variable-temperature evaporator 730 that form a refrigeration loop. When refrigeration is needed, the refrigerant is compressed into a high-temperature, high-pressure gas by the compressor 710, then passes through the condenser to become a medium-temperature, high-pressure liquid, and finally returns to the compressor 710 as a low-temperature, low-pressure gas through the variable-temperature evaporator 730, completing one refrigeration cycle. The refrigerant is at a medium temperature in the condenser to exchange heat with the outside environment, while it is at a low temperature in the variable-temperature evaporator 730 to exchange heat with the internal air of the variable-temperature chamber 110 for refrigeration. Furthermore, because the condenser is located close to the variable-temperature chamber 110, the heat released by the condenser can be used to heat the variable-temperature chamber 110, improving energy efficiency and reducing operating costs.

[0086] It should be noted that the variable temperature evaporator 730 operates when the variable temperature chamber 110 is in refrigeration or freezing mode; the variable temperature evaporator 730 does not operate when the variable temperature chamber 110 is in heating mode.

[0087] In some embodiments, such as Figure 2 As shown, the variable-temperature evaporator 730 and the first heating element 310 are arranged vertically, which can make reasonable use of the vertical space of the variable-temperature chamber 110 and optimize the spatial layout. Simultaneously, the upper variable-temperature evaporator 730 can quickly absorb heat from the variable-temperature chamber 110 and allow the cold air to flow naturally downwards, covering the entire variable-temperature chamber 110 and improving cooling efficiency. The lower first heating element 310 can quickly transfer heat to the bottom of the variable-temperature chamber 110 and allow the heat to flow naturally upwards, improving heating efficiency and defrosting efficiency of the variable-temperature evaporator 730, and saving energy.

[0088] In some embodiments, such as Figure 2 As shown, the storage device also includes a sensor switch 600, which is communicatively connected to the heating assembly 300 and used to sense the opening and closing state of the temperature-controlled door 210. When the sensor switch 600 senses that the temperature-controlled door 210 is open, the heating assembly 300 does not operate. In this embodiment, the sensor switch 600 is located on the temperature-controlled door 210. Of course, in other embodiments, the sensor switch 600 can also be located on the temperature-controlled inner liner 101; this embodiment does not impose specific limitations on this.

[0089] It is understandable that regardless of whether the heating component 300 is working when the temperature-controlled door 210 is closed, as long as the temperature-controlled door 210 is open, the heating component 300 will not work based on the sensing signal of the induction switch 600. This can not only reduce energy consumption, but also reduce the safety risks caused by heat leakage and improve the reliability of the storage equipment.

[0090] In some embodiments, such as Figure 2 As shown, the storage device also includes a temperature sensing module and a pressure sensing module. The temperature sensing module is located inside the variable temperature chamber 110 and is communicatively connected to the heating component 300 and the pressure relief component 400 to obtain the temperature signal of the variable temperature chamber 110. The pressure sensing module is located inside the variable temperature chamber 110 and is communicatively connected to the pressure relief component 400 to obtain the pressure signal of the variable temperature chamber 110.

[0091] The pressure relief assembly 400 connects or disconnects the variable temperature chamber 110 from the outside world based on temperature and pressure signals. Temperature sensing modules include, but are not limited to, thermocouples, thermistors, platinum resistance thermometers (RTDs), or temperature ICs. Pressure sensing modules include, but are not limited to, mechanical pressure sensors, semiconductor pressure sensors, capacitive pressure sensors, inductive pressure sensors, or resonant pressure sensors.

[0092] Understandably, on the one hand, the temperature sensing module is installed in the variable temperature compartment 110 to monitor the temperature changes in the variable temperature compartment 110 in real time, so as to promptly determine and follow up on the current mode of the variable temperature compartment 110 (including heating mode, refrigeration mode, and freezing mode), and then adjust the operating status of the heating component 300 and the refrigeration system in a timely manner (for example, after switching to the heating mode, if the current temperature of the variable temperature compartment 110 reaches the first threshold, the storage device can adjust the heating power of the first heating element 310 and the second heating element 320), which plays a role in energy saving, environmental protection, and improving automation. On the other hand, the air pressure sensing module is installed in the variable temperature compartment 110 to monitor the air pressure changes in the variable temperature compartment 110 in real time, and, in conjunction with the current temperature, control the opening and closing of the pressure relief valve 410 to adjust the internal and external air pressure of the variable temperature compartment 110 in a timely manner, thereby improving the reliability of the storage device.

[0093] In some embodiments, such as Figure 2 As shown, the storage device also includes a humidity sensing module, which is installed in the variable temperature chamber 110 and communicates with the heating component 300 to obtain the humidity signal of the variable temperature chamber 110. The humidity sensing module includes, but is not limited to, resistive humidity sensors, capacitive humidity sensors, or carbon humidity-sensitive elements.

[0094] Understandably, the humidity sensing module is installed in the variable temperature chamber 110 to monitor humidity changes in the variable temperature chamber 110 in real time, and then adjust the operating status of the heating component 300 and the refrigeration system in a timely manner (for example, in heating mode, if the current humidity of the variable temperature chamber 110 reaches the second preset level, the storage device can increase the heating power of at least one of the first heating element 310 and the second heating element 320 to reduce the humidity) to optimize the storage effect of the items.

[0095] In some embodiments, such as Figure 2 As shown, the temperature sensing module, air pressure sensing module, and humidity sensing module are integrated to form a temperature, humidity, and pressure sensor 500, which reduces wiring space and signal interference, optimizes the layout within the variable temperature chamber 110, and lowers installation complexity, failure risk, and manufacturing cost. Of course, in other embodiments, two of the temperature sensing module, air pressure sensing module, and humidity sensing module may also be integrated; this embodiment does not impose specific limitations on this.

[0096] In some embodiments, such as Figure 1 and Figure 2As shown, the cabinet 100 further forms a refrigerator compartment 120 and a freezer compartment 130. The storage device also includes a refrigerator door 220 and a freezer door 230. The refrigerator door 220 is closable and can be installed on the cabinet 100 to close the refrigerator compartment 120, and the freezer door 230 is closable and can be installed on the cabinet 100 to close the freezer compartment 130. The refrigerator door 220 and the freezer door 230 are, but are not limited to, rotating doors or drawer doors. It should be noted that the shape and size of the refrigerator compartment 120 and the freezer compartment 130 can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0097] Understandably, by setting up a refrigerated compartment 120, a variable-temperature compartment 110, and a freezer compartment 130, multiple needs such as refrigeration, heating, and freezing can be met simultaneously, thereby improving the multifunctionality of the storage equipment. At the same time, the refrigerated compartment 120, the variable-temperature compartment 110, and the freezer compartment 130 are respectively equipped with a refrigerated door 220, a variable-temperature door 210, and a freezer door 230, improving the airtightness of each compartment (including the refrigerated compartment 120, the variable-temperature compartment 110, and the freezer compartment 130).

[0098] For example, to facilitate understanding of the differences between the freezer compartment 130, the refrigerator compartment 120, and the variable temperature compartment 110, the temperature of the freezer compartment 130 is typically no higher than -14°C, and it is mainly used to store meat, fish, frozen foods, and other foods that require frozen preservation. The temperature of the refrigerator compartment 120 is typically between 0 and 10°C, and it is mainly used to store vegetables, fruits, dairy products, eggs, and other foods that need to be kept at a low temperature but not frozen. The variable temperature compartment 110 can achieve a temperature range of -20 to 40°C, providing a wider temperature adjustment range and greater flexibility to adjust the temperature according to the specific needs of the stored foods. For example, it can store certain fruits that need to be stored at room temperature or certain beverages that need to be heated for preservation.

[0099] It should be noted that in some embodiments, the refrigerator compartment 120 and the freezer compartment 130 are directly formed by the variable temperature inner liner 101. Of course, in other embodiments, the cabinet 100 also includes a refrigerator inner liner and a freezer inner liner, with the refrigerator inner liner forming the refrigerator compartment 120 and the freezer inner liner forming the freezer compartment 130. This embodiment does not impose specific limitations on this.

[0100] In some embodiments, such as Figure 1 and Figure 2 As shown, the refrigeration compartment 120, the variable temperature compartment 110, and the freezer compartment 130 are arranged sequentially in the vertical direction, which reduces the floor space of the entire storage equipment and improves the compactness of the storage equipment.

[0101] In some embodiments, such as Figure 2As shown, the storage device also includes a refrigerated evaporator 740 and a frozen evaporator 750. The refrigerated evaporator 740, the frozen evaporator 750, and the variable-temperature evaporator 730 are connected in parallel.
