Description

Technical Field

[0001] The utility model relates to a multifunctional food storage container. Background Art

[0002] Since different foods require different storage conditions, the food storage containers on the market have a single function and can only be used for one type of food. Currently, the more commonly used food storage containers are vacuum constant temperature rice boxes and refrigerators. Among them, vacuum constant temperature rice boxes are devices that use vacuum technology and constant temperature control technology to store rice. Rice in a vacuum state and at a suitable low temperature can be stored for a longer time, and the flavor can be better guaranteed; refrigerators are used to store vegetables, meat and other ingredients at low temperatures. In recent years, as kimchi has become popular, kimchi refrigerators specifically used for storing and fermenting kimchi have been widely used. They can provide more suitable temperature, humidity and air flow conditions for kimchi fermentation. Kimchi refrigerators are usually lower in temperature, higher in humidity, and have less air flow than traditional refrigerators. These characteristics help kimchi stay fresh before it becomes sour and can extend the shelf life of kimchi.

[0003] Some people prefer both rice and kimchi. In this case, they need to have a vacuum constant temperature rice box and a kimchi refrigerator, which not only takes up a large indoor space but also has a high cost of use.

[0004] In addition, in hot weather such as summer, if the vacuum constant temperature rice box is opened for a long time to take out rice, the inner liner of the rice box, which is still in a low temperature state, will easily condense when it encounters external hot air.

[0031] See also Figure 1 and Figure 2The utility model discloses a multifunctional food storage container, comprising: a shell component 100, wherein a first container 200 for storing rice and a second container 300 for storing kimchi are arranged side by side in the shell component 100, the first container 200 has a first opening upward, and the second container 300 has a second opening upward, the shell component 100 is movably provided with a first door panel 210 for opening or closing the first opening and a second door panel 310 for opening or closing the second opening, the first container 200 is connected with an exhaust component 400 capable of extracting gas inside the first container 200, the shell component 100 is provided with a first refrigeration component for cooling the first container 200 and a second refrigeration component for cooling the second container 300, the first container 200 and the second container 300 are respectively provided with a first temperature sensing element and a second temperature sensing element, the first temperature sensing element, the second temperature sensing element, the first refrigeration component and the second refrigeration component are all connected to a control module, and the control module can control the second refrigeration component to cool the second container 300 to a temperature value lower than the temperature value after the first refrigeration component cools the first container 200.

[0032] The vacuum assembly 400 of the above multifunctional food storage container extracts the gas in the first container 200, and the first refrigeration assembly cooperates with the first temperature sensing element to cool the first container 200 to a temperature suitable for storing rice. The second refrigeration assembly cooperates with the second temperature sensing element to cool the second container 300 to a lower temperature than the first container 200 to be suitable for storing kimchi, thereby realizing the function of storing rice and kimchi at the same time. The multifunctional food storage container has a compact structure, which is beneficial to reduce the placement space and reduce the use cost.

[0033] See also Figure 2 and Figure 3In some embodiments of the utility model, a compressor 510, a heat exchange component 520, a first throttling component 530, a first heat exchange tube group 540, a second throttling component 550 and a second heat exchange tube group 560 are arranged inside the shell component 100, the compressor 510 is connected to the heat exchange component 520, the heat exchange component 520 is respectively connected to the first throttling component 530 and the second throttling component 550 through a first solenoid valve 610, the first solenoid valve 610 is used to control the refrigerant flow through the first throttling component 530 and the second throttling component 550 respectively, the two ends of the first heat exchange tube group 540 are respectively connected to the first throttling component 530 and the compressor 510, the two ends of the second heat exchange tube group 560 are respectively connected to the second throttling component 550 and the compressor 510, the first heat exchange tube group 540 and the second heat exchange tube group 560 are respectively in contact with the wall surface of the first container 200 and the wall surface of the second container 300. It can be understood that the compressor 510, the heat exchange component 520, the first throttling component 530 and the first heat exchange tube group 540 constitute a refrigeration system, which constitutes the first refrigeration component. The compressor 510, the heat exchange component 520, the second throttling component 550 and the second heat exchange tube group 560 constitute another refrigeration system, which constitutes the second refrigeration component. The heat exchange component 520 is a condenser shared by the two refrigeration systems. The first solenoid valve 610 is used to divert the refrigerant to control the refrigerant flow entering the two refrigeration systems, thereby realizing the use of a single compressor 510 to cool the first container 200 and the second container 300 according to the preset temperature respectively, with good refrigeration effect, compact structure and low cost.

[0034] See also Figure 3In some embodiments of the present invention, the output end of the compressor 510 is provided with a valve body 620 capable of switching the refrigerant to first pass through the heat exchange component 520 or first pass through the first heat exchange tube group 540 and the second heat exchange tube group 560. It should be noted that when the weather is hot, if the first door panel 210 is opened for a long time, the first container 200, which is still in a low temperature state, is prone to condensation when encountering external hot air, and the rice in contact with the inner wall of the first container 200 will become damp and moldy, affecting the quality and storage life of the rice. The above structure directly uses the first solenoid valve 610 to cut off the refrigerant entering the second heat exchange tube group 560, and the valve body 620 switches the output end of the compressor 510 to first enter the first heat exchange tube group 540, and the refrigerant then passes through the first throttling component 530, the heat exchange component 520 and the compressor 510. At this time, the first heat exchange tube group 540 acts as a condenser, and the heat exchange component 520 acts as an evaporator, that is, the refrigeration system can be used to heat the first container 200, so that the temperature of the first container 200 is close to room temperature, and no condensation will occur when the first door panel 210 is opened to take out the rice, thereby preventing the rice from getting damp and moldy, thereby ensuring the quality and life of the stored rice.

[0035] See also Figure 4 In some embodiments of the utility model, the first container 200 is in a rectangular cylindrical shape with four side panels connected in sequence, and the adjacent side panels are perpendicular to each other. The first heat exchange tube group 540 has four first curved sections respectively abutting against the outer side walls of the four side panels. The first curved section is serpentine along the height direction of the corresponding side panel. The upper end of the first curved section is connected to the upper end of an adjacent first curved section, and the lower end of the first curved section is connected to the lower end of another adjacent first curved section, or the lower end of the first curved section is connected to the first throttling assembly 530 or the compressor 510. The first heat exchange tube group 540 with the above structure is in full contact with the first container 200, and has a large heat exchange area, which is conducive to quickly cooling the first container 200 to the temperature for storing rice, and the connection between the four first curved sections is very convenient, which is conducive to production and manufacturing.

[0036] See also Figure 2 and Figure 4In some embodiments of the utility model, a heating wire 700 is coiled around the outer peripheral wall of the first container 200, and the heating wire 700 is connected to the control module and is located at the side of the first heat exchange tube group 540. In view of the fact that condensation is likely to occur when the external hot air encounters the first container 200 in a low temperature state, a function button electrically connected to the control module is provided on the housing component 100. When the user triggers the function button to prepare to open the first door panel 210, the control module drives the first refrigeration component to suspend work, and the heating wire 700 starts to work. The heating wire 700 coiled around the outer peripheral wall of the first container 200 can quickly transfer heat to the first container 200. When the temperature of the first container 200 is close to room temperature, condensation will not occur when the first door panel 210 is opened to take out rice, thereby preventing the rice from getting damp and moldy.

[0037] See also Figure 4 In some embodiments of the utility model, in order to make full use of the contact area of ​​the outer wall of the first container 200 without interfering with the first heat exchange tube group 540, the heating wire 700 includes a first heating section 710 and a second heating section 720 respectively located on both sides of the first heat exchange tube group 540 and parallel to the curved path of the first heat exchange tube group 540, one end of the first heating section 710 is connected to one end of the second heating section 720, and the other end of the first heating section 710 and the other end of the second heating section 720 are both provided with power terminals, that is, the first heating section 710 and the second heating section 720 are connected in series, and the two ends of the whole composed of the first heating section 710 and the second heating section 720 are used for power connection.

[0038] In some embodiments of the utility model, the housing assembly 100 is further provided with a third temperature sensing element for detecting the external temperature and connected to the control module. The third temperature sensing element detects the temperature value of the external temperature as A, and the first temperature sensing element detects the temperature value of the first container 200 as B. When AB≥3°C is satisfied, the control module can drive the heating wire 700 to work. It should be noted that when the temperature of the first container 200 is lower than the room temperature by more than 3°C, the control module controls the heating wire 700 to work. When the temperature difference between the first container 200 and the room temperature is less than 3°C, the control module controls the heating wire 700 to stop working. It is known through experiments that when the temperature difference is less than 3°C, no condensation will occur, thereby reducing the power consumption of the heating wire 700 and accelerating the speed at which the first door panel 210 can be opened. In addition, the heating wire 700 that stops power supply still has residual heat and can continue to transfer the residual heat to the first container 200. In addition, when the room temperature is lower than the temperature of the first container 200, the heating wire 700 does not need to start working.

[0039] See also Figure 2 and Figure 5In some embodiments of the utility model, the second container 300 is provided with an annular flange 320 protruding outward at the second opening, the second door panel 310 abuts against the upper surface of the annular flange 320 to close the second container 300, the second heat exchange tube group 560 is arranged around the outer peripheral wall of the second container 300, and a heating pipe section 570 abutting against the lower surface of the annular flange 320 is provided between the compressor 510 and the heat exchange assembly 520. It should be noted that the second door panel 310 generally has a sealing strip abutting against the upper surface of the annular flange 320, and the annular flange 320 and the second container 300 as a whole are at a relatively low temperature. At this time, there is also the problem of hot air being cooled and forming condensed water droplets on the sealing strip. The above scheme cleverly uses the pipeline between the condenser of the refrigeration system and the compressor 510 as the heating pipe section 570, so that the part of the annular flange 320 and the sealing strip of the second door panel 310 that contacts is in a warm state to avoid condensation.

[0040] See also Figure 2 In some embodiments of the utility model, in order to rationally utilize the internal space of the shell assembly 100 and avoid chaotic layout of components, a horizontally arranged partition 110 is provided inside the shell assembly 100, and the partition 110 divides the interior of the shell assembly 100 into an upper mounting cavity and a lower mounting cavity. The first container 200 and the second container 300 are both placed on the upper surface of the partition 110 to be located within the upper mounting cavity, and the compressor 510, the heat exchange assembly 520, the first throttling assembly 530, and the second throttling assembly 550 are all located within the lower mounting cavity.

[0041] See also Figure 2 In some embodiments of the utility model, the vacuum assembly 400 includes a vacuum pump 410, a one-way valve 420, a pressure relief valve 430 and an exhaust pipe 440 which are connected in sequence through pipelines. The exhaust pipe 440 is arranged on the first door panel 210 and connected to the interior of the first container 200. The pressure relief valve 430 can connect the external gas and the pipeline to restore the interior of the first container 200 to a normal pressure state.

[0042] Rice can be stored longer in a vacuum state, and its flavor can be better guaranteed. When the vacuum pump 410 of the vacuum assembly 400 is working, the air inside the first container 200 passes through the exhaust pipe 440 and the one-way valve 420 and is discharged from the exhaust end of the vacuum pump 410. The setting of the one-way valve 420 can prevent the air from flowing back into the first container 200. When it is necessary to open the first door panel 210, since the first container 200 is in a vacuum state or a low-pressure state, the pressure difference between the inside and outside of the first container 200 is large, which makes it difficult for the user to directly open the first door panel 210. At this time, it is only necessary to open the pressure relief valve 430, and the external air can enter the exhaust pipe 440 and then enter the first container 200, without the need to set up an additional air supply device, thereby reducing costs.

[0043] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
