Description

Refrigerator with a refrigerator body

Technical Field

The invention relates to the field of household appliances, in particular to a refrigerator.

Background

With the increasing social development and the increasing living standard of people and the increasing pace of life of people, people often purchase a large number of articles to be placed in various refrigerators, but for leaf vegetables and melon and fruit foods, the low temperature in the storage space of the refrigerator can not only cause the phenomenon of wrinkling and marking of the surfaces of the foods, but also affect the original taste and nutrition of the foods.

In the fresh-keeping technology of the refrigerator, oxygen is closely related to the oxidization and respiration of food in the refrigerator. The slower the respiration of the food, the lower the oxidation of the food and the longer the fresh-keeping time. The oxygen content in the air is reduced, and the fresh-keeping agent has obvious effect on food fresh-keeping. Currently, in order to reduce the oxygen content in a refrigerator, the prior art generally uses vacuum preservation or additionally provides a deoxidizing device for low-oxygen preservation. However, the vacuum preservation operation is generally complicated and is very inconvenient to use; the deoxidizing device usually uses electrolyte and the like to deoxidize, and the device is complex and has no obvious deoxidizing effect.

The air-conditioning preservation technology generally refers to a technology for prolonging the storage life of food by adjusting the gas atmosphere (gas component ratio or gas pressure) of an enclosed space where a storage object is located, and the basic principle is as follows: in a certain closed space, a gas atmosphere different from the normal air composition is obtained through various regulation modes so as to inhibit physiological and biochemical processes and microbial activities which lead to the spoilage of stored materials (usually food materials). In particular, in the present application, the modified atmosphere preservation in question will be specifically directed to modified atmosphere preservation techniques in which the ratio of the gas components is adjusted.

Those skilled in the art will appreciate that normal air components include (in volume percent, hereinafter the same): about 78% nitrogen, about 21% oxygen, about 0.939% noble gases (helium, neon, argon, krypton, xenon, radon), 0.031% carbon dioxide, and 0.03% other gases and impurities (e.g., ozone, nitric oxide, nitrogen dioxide, water vapor, etc.). In the field of controlled atmosphere preservation, a mode of filling nitrogen-rich gas into an enclosed space to reduce the oxygen content is generally adopted to obtain a nitrogen-rich and oxygen-poor preservation gas atmosphere. Here, the person skilled in the art knows that the nitrogen-rich gas refers to a gas having a nitrogen content exceeding that of the above-mentioned normal air, for example, the nitrogen content thereof may be 95% to 99% or even higher; the nitrogen-rich and oxygen-poor fresh-keeping gas atmosphere refers to a gas atmosphere with nitrogen content exceeding the nitrogen content in the normal air and oxygen content being lower than the oxygen content in the normal air.

The air-conditioned fresh-keeping space in the prior art is usually realized by a sealed drawer or other sealed containers, the height of the sealed containers is lower, the sealed drawer also needs the action of drawer drawing, the food or tableware with higher height cannot be put down, and the food or tableware with larger volume and higher height and the food contained in the higher tableware cannot be contained.

Detailed Description

The embodiment provides a refrigerator, and the inside storing area in its fresh-keeping space can set up in a flexible way, promotes the convenience of storing all kinds of food materials, guarantees that the food materials that the volume is great, the height is higher and the food materials that hold in higher tableware also can put into fresh-keeping space smoothly, promotes user's use experience. Fig. 1 is a schematic structural view of a refrigerator 100 according to an embodiment of the present invention, fig. 2 is a schematic structural view of a connection between a partition 112 and a lifting device 130 in the refrigerator 100 according to another embodiment of the present invention, and fig. 3 is a schematic structural view of the lifting device 130 in fig. 2. As shown in fig. 1 to 3, the refrigerator 100 may generally include: a case 110, a door 120, a partition 112, and a lifting device 130.

Wherein, the interior of the case 110 defines a storage space, wherein the storage space includes a fresh-keeping space 111. The door 120 is disposed on the front surface of the case 110 for closing the storage space. The partition 112 is transversely arranged in the fresh-keeping space 111 to divide the fresh-keeping space 111 into a plurality of storage areas. The lifting device 130 may be configured to controllably move the diaphragm 112 up and down. The partition 112 may be moved up and down so that the height of the storage area above and below it may be varied as desired. The refrigerator 100 of this embodiment, the inside storing area in fresh-keeping space 111 can set up in a flexible way, promotes the convenience of storing all kinds of food materials, guarantees that the food materials that the volume is great, the height is higher and hold in higher tableware also can put into fresh-keeping space 111 smoothly, promotes user's use experience.

Specifically, the number and structure of the storage spaces defined in the case 110 may be configured according to the requirement, and fig. 1 shows two storage spaces arranged side by side above and two storage spaces arranged up and down below, and the total of four storage spaces. The storage space can be configured as a refrigerating space, a freezing space, a temperature changing space or a fresh keeping space 111 according to the purpose. Each storage space may store items using racks or drawers. For example, the storage space at the upper left in fig. 1 is provided with one rack and two drawers, which in a preferred embodiment may be dry and wet split drawers.

In a specific embodiment, the storage space at the upper right of fig. 1 may be provided as the fresh space 111. The fresh keeping space 111 may be provided with one or more partitions 112 that can move up and down, or may be provided with a partition 112 that can move up and down and a stationary rack in a mixed manner. In fig. 1, two storage spaces are arranged side by side in the upper direction, and when the door 120 on one side is closed, the storage space is a closed space, that is, the opening and closing of the door 120 on the other storage space does not affect the closed state. Therefore, the door 120 of the upper left storage space, whether opened or closed, does not affect the airtight state of the fresh-keeping space 111.

In order to further ensure the sealing effect of the fresh-keeping space 111, the internal gas atmosphere will not change easily even when the door 120 of the fresh-keeping space 111 is opened, and a retractable baffle plate may be disposed at the front end of the baffle plate 112 up and down to adapt to the baffle plate 112 to move up and down to different positions. The length to which the upper and lower retractable baffles are respectively stretched is determined according to the position of the baffle 112. Regardless of the position to which the partition 112 is moved, the upper retractable barrier may be pulled upward so that the storage area above it is a closed space; the telescopic baffle below can be stretched downwards, so that the storage area below the telescopic baffle is a closed space. When it is desired to take and place the food items in the upper and lower storage areas of the partition 112, the corresponding retractable barrier may be retracted. The telescopic baffle can realize a telescopic effect in a rolling shutter mode or a sliding door mode.

The door 120 may be disposed corresponding to the storage spaces, i.e., each storage space corresponds to one or more doors 120. The number of storage spaces and the door 120, and the functions of the storage spaces may be actually selected according to the specific situation. The refrigerator 100 of the present embodiment corresponds to two storage spaces arranged side by side above and below, and four storage spaces are provided with four door bodies 120 respectively. The door 120 may be pivotally disposed on the front surface of the case 110, and may be opened in a drawer manner, so as to realize a drawer-type storage space, where the drawer-type storage space is often provided with a metal sliding rail, so that the effect of opening and closing the drawer is light and the noise is reduced. The door opening mode of the two storage spaces arranged side by side above and right and left of the refrigerator 100 in this embodiment is a pivot opening mode, and the door opening mode of the two storage spaces arranged below and up is a drawer opening mode.

As shown in fig. 2 and 3, the elevating device 130 may include: the refrigerator comprises a motor 131, a nut 132, a screw rod 133 and a guide rod 134, wherein the motor 131 is fixed with the inner container of the refrigerator 100 and is configured to drive the screw rod 133 to rotate. In a specific embodiment, the motor 131 may be disposed in a compressor compartment of the refrigerator 100, i.e., the motor 131 may be fixedly connected to a liner at the compressor compartment. The case 110 may generally include an external casing, an internal liner, and an intermediate heat-insulating layer, where the heat-insulating layer may effectively insulate the heat from the heat in the refrigerator 100, and may also prevent the heat from affecting the temperature in the refrigerator 100.

As shown in fig. 3, the screw rod 133 and the guide rod 134 are vertically arranged, and the nut 132 is sleeved on the screw rod 133 and the guide rod 134. After the motor 131 is started, the screw rod 133 is driven to rotate, and the nut 132 sleeved on the screw rod 133 moves up and down. That is, the rotary motion of the screw rod 133 is converted into the linear motion of the nut 132. The guide rod 134 is arranged to play a guiding role, so that the nut 132 also sleeved on the guide rod 134 can smoothly vertically move up and down without transverse offset.

The lifting device 130 may further include: and a bracket 135, wherein the bracket 135 is fixedly connected with the nut 132, and the partition 112 is erected above the bracket 135. In a preferred embodiment, the partition 112 may be made of glass, and may have decorative strips around the periphery. Wherein the side molding may be fixedly coupled to the bracket 135 by a screw. That is, the partition 112 can be screwed onto the support 135, so that the partition 112 is more stable and cannot easily move and fall. The lifting device 130 may further include: an electric control circuit 136 connected to the motor 131 to control an operation state of the motor 131 after power is applied.

The lifting device 130 may be configured to: under the condition that the motor 131 is started, the nut 132 drives the bracket 135 to move up and down, and then drives the partition 112 to move up and down. Specifically, the open/close state of the lifting device 130 may be determined according to the storage requirements of the storage areas above and below the partition 112. For example, if higher food or tableware is required to be stored above the partition 112, the lifting device 130 can be controlled to be opened, so that the nut 132 drives the bracket 135 and the partition 112 to move downwards; if higher food or tableware needs to be stored below the partition 112, the lifting device 130 can be controlled to be opened, so that the nut 132 drives the bracket 135 and the partition 112 to move upwards.

In a specific embodiment, the upward or downward movement of the nut 132, and thus the bracket 135 and the partition 112, may be achieved by forward and reverse rotation of the motor 131. For example, the control motor 131 rotates forward, the nut 132 can move downwards, and then the bracket 135 and the partition 112 are driven to move downwards; the motor 131 is controlled to rotate reversely, and the nut 132 can move upwards, so that the bracket 135 and the partition plate 112 are driven to move upwards. It should be noted that, the correspondence between the forward rotation and the reverse rotation of the motor 131 and the upward and downward movement of the nut 132 may be the same as above, or may be opposite, for example, the forward rotation of the motor 131 corresponds to the upward movement of the nut 132, the reverse rotation of the motor 131 corresponds to the downward movement of the nut 132, and may be set according to the actual situation, for example, the threaded relationship between the nut 132 and the screw rod 133.

In a preferred embodiment, two brackets 135 are provided on the left and right sides of the bottom of the partition 112. That is, one partition 112 is provided with two brackets 135 on the left and right sides of the bottom, respectively, so that the balance and stability of the partition 112 can be further ensured. In addition, two lifting devices 130 may be correspondingly arranged at the same time of arranging the two brackets 135, so that the brackets 135 on the left side and the right side are synchronously driven to move upwards or downwards.

One or more nuts 132 may be provided on the screw rod 133 and the guide rod 134 of one lifting device 130. As shown in fig. 3, two nuts 132 are provided on the screw rod 133 and the guide rod 134 of one lifting device 130. The upper and lower nuts 132 may be respectively corresponding to one partition 112, that is, the plurality of partition 112 may share the lifting devices 130 on both sides, and only a plurality of corresponding nuts 132 may be provided on the screw rod 133 and the guide rod 134. The process of moving the diaphragm 112 up and down is similar to the process described above in which the single diaphragm 112 is driven by the nut 132. Only the plurality of partitions 112 may move up and down simultaneously, and the distance between the adjacent two partitions 112 may not be changed, but the area of the upper portion of the upper partition 112 and the area of the lower portion of the lower partition 112 may be changed in height. Alternatively, asynchronous control of the plurality of nuts 132 may be achieved in some other manner, such that different movements of different baffles 112 may be achieved, such that the distance between adjacent baffles 112 may also vary.

It is mentioned that the motor 131 of the lifting device 130 is disposed in the compressor compartment, and other components of the lifting device 130, such as the screw rod 133, the guide rod 134, the nut 132, and the bracket 135, may be disposed in the storage space. The lead screw 133, the guide rod 134, the nut 132 and the bracket 135 of the embodiment can be arranged in the fresh-keeping space 111, so that flexible adjustment of the storage area inside the fresh-keeping space 111 is realized, food materials with larger volume and higher height and food materials contained in higher tableware are ensured to be smoothly placed in the fresh-keeping space 111, and the fresh-keeping effect of various food materials is improved.

Fig. 4 is a schematic structural view of an air-conditioning membrane module in a refrigerator 100 according to an embodiment of the present invention, fig. 5 is a schematic exploded view of the air-conditioning membrane module shown in fig. 4, fig. 6 is a schematic structural view of a support frame 32 in the air-conditioning membrane module shown in fig. 5, and fig. 7 is a schematic structural view of the support frame 32 in the air-conditioning membrane module shown in fig. 5, viewed from another angle.

As shown in fig. 1, the rear wall of the fresh-keeping space 111 is provided with an exhaust hole. And, the vent hole can be provided with an air conditioning membrane assembly, and the surrounding space of the air conditioning membrane assembly is communicated with the fresh-keeping space 111. In order to show the location of the vent, the air conditioning module is not labeled in fig. 1, but in summary, the air conditioning module is disposed at the vent. Each of the modified atmosphere membrane modules has at least one modified atmosphere membrane and an oxygen-enriched gas collection chamber and is configured to allow more oxygen in the spatial gas stream surrounding the modified atmosphere membrane module to permeate through the modified atmosphere membrane into the oxygen-enriched gas collection chamber relative to nitrogen therein. And the exhaust hole is communicated with the oxygen-enriched gas collecting cavity. The space around the air-conditioning membrane component is communicated with the fresh-keeping space 111, so that the air-conditioning fresh-keeping of the fresh-keeping space 111 can be realized.

In this embodiment, the air conditioning membrane is an oxygen enrichment membrane 33, and the air conditioning membrane module may be an oxygen enrichment membrane module 31. Oxygen-enriched membrane assembly 31 of the present embodiment may generally comprise: a support frame 32 and an oxygen-enriched membrane 33 disposed on the support frame 32. Oxygen-enriched membrane 33 is permeable to all gases, except for different gases that have different degrees of permeation. The permeation of gas through oxygen-enriched membrane 33 is a complex process, and the permeation mechanism is generally that gas molecules are firstly adsorbed to the surface of oxygen-enriched membrane 33 to be dissolved, then diffused in oxygen-enriched membrane 33, and finally desorbed from the other side of oxygen-enriched membrane 33. Oxygen-enriched membrane separation techniques rely on the difference in solubility and diffusion coefficients of different gases in oxygen-enriched membrane 33 to effect separation of the gases. When the mixed gas permeates the oxygen-enriched membrane 33 under the action of a certain driving force (pressure difference or pressure ratio of two sides of the oxygen-enriched membrane 33), gas with relatively high permeation rate such as oxygen, hydrogen, helium, hydrogen sulfide, carbon dioxide and the like is enriched on the permeation side of the oxygen-enriched membrane 33, and gas with relatively low permeation rate such as nitrogen, carbon monoxide and the like is enriched on the retention side of the oxygen-enriched membrane 33, so that the purpose of separating the mixed gas is achieved.

The support frame 32 has a first surface 321 and a second surface 322 that are parallel to each other, and the support frame 32 is formed with a plurality of air flow passages 323 extending over the first surface 321, over the second surface 322, and through the support frame 32 to communicate the first surface 321 and the second surface 322, respectively. The plurality of gas flow channels 323 collectively form an oxygen-enriched gas collection chamber. At least one oxygen-enriched membrane 33 of the present embodiment, preferably, two planar oxygen-enriched membranes 33 are respectively laid on the first surface 321 and the second surface 322 of the support frame 32. The oxygen-enriched membrane 33 may allow oxygen in the outside air to permeate through the oxygen-enriched membrane 33 into the oxygen-enriched gas collection chamber to form oxygen-enriched gas when the inside pressure thereof is smaller than the outside pressure, thereby making the outside air into nitrogen-enriched gas.

In some embodiments, the support frame 32 includes a bleed hole 324 in communication with at least one of the aforementioned plurality of gas flow channels 323, and the bleed hole 324 may be in direct communication with an oppositely disposed vent, such that the vent hole may be in communication with the oxygen-enriched gas collection chamber as mentioned above. Thus, the oxygen-enriched gas in the oxygen-enriched gas collecting cavity can be discharged only by communicating the exhaust device with the exhaust hole. In a specific embodiment, the exhaust device may be an air pump.

As the oxygen-enriched gas in the oxygen-enriched gas collection chamber is pumped out, the oxygen in the air outside the oxygen-enriched membrane module 31 is in a negative pressure state, so that oxygen in the air outside the oxygen-enriched membrane module 31 continuously permeates through the oxygen-enriched membrane 33 to enter the oxygen-enriched gas collection chamber, and the air outside the oxygen-enriched membrane module 31 forms a nitrogen-enriched atmosphere. In some embodiments, the aforementioned plurality of gas flow passages 323 formed inside the support frame 32 may be a plurality of cavities in communication with the pumping holes 324.

In some embodiments, referring to fig. 5 and 6, for further ease of installation, oxygen-enriched membrane 33 may be pre-secured in mounting groove 327 of support frame 32 with a bead of double sided tape 325, followed by a bead of sealant 326 filling loop groove 328 of support frame 32 to sealingly mount oxygen-enriched membrane 33 in mounting groove 327 of support frame 32.

The oxygen-enriched membrane module 31 uses the difference of permeation rates when each component gas in the air permeates the oxygen-enriched membrane 33, and the oxygen in the air preferentially passes through the oxygen-enriched membrane 33 under the driving of pressure difference to obtain oxygen. In other embodiments, the air-conditioning membrane may be a hollow fiber membrane, and the air-conditioning membrane module is a hollow fiber membrane module, where the hollow fiber membrane module uses different transmittance of each component gas in the air through the hollow fiber membrane, and oxygen molecules preferentially permeate the hollow fiber membrane to obtain oxygen because the oxygen molecules are smaller than the nitrogen molecules.

In a specific embodiment, as shown in fig. 1, the rear wall of the fresh-keeping space 111 may be provided with a first air vent 141 and a second air vent 142, wherein the first air vent 141 is located above the second air vent 142, and air conditioning membrane assemblies are correspondingly disposed at the first air vent 141 and the second air vent 142. And, the elevating device 130 may be configured to: the partition 112 is controllably moved up and down between the first and second air discharge holes 141 and 142 to partition the fresh space 111 into the first region 101 where the first air discharge hole 141 is located and the second region 102 where the second air discharge hole 142 is located.

The partition 112 moves up and down between the first air vent 141 and the second air vent 142, so that the first area 101 above the partition 112 corresponds to the first air vent 141 and an air conditioning membrane assembly, and the second area 102 below corresponds to the second air vent 142 and an air conditioning membrane assembly, so that the first area 101 and the second area 102 can both realize the adjustment of the gas atmosphere. The condition that no exhaust hole and no air conditioning membrane component exist above or below the partition 112 and the adjustment of the air atmosphere cannot be realized is avoided. The case where a plurality of separators 112 are provided may be similarly provided as described above in consideration of the above. For example, two partition plates 112 may be provided, and three exhaust holes of upper, middle and lower may be provided, one partition plate 112 moving up and down between the upper and middle exhaust holes, and the other partition plate 112 moving up and down between the middle and lower exhaust holes.

Fig. 8 is a schematic view illustrating a connection structure of the first and second air discharge holes 141 and 142 and the air pump in the refrigerator 100 according to an embodiment of the present invention, and fig. 9 is a schematic view illustrating a structure of the air pump assembly in the refrigerator 100 according to an embodiment of the present invention. As shown in fig. 8 and 9, the refrigerator 100 of the present embodiment may further include: and the suction pump is arranged in the compressor bin, and the inlet end of the suction pump is controllably communicated with the first exhaust hole 141 and the second exhaust hole 142 through the pipeline 50 and the pipeline switching mechanism 51. It is mentioned above that the exhaust holes are in communication with the oxygen-enriched gas collection chamber, and therefore, the air pump is in controlled communication with the first exhaust hole 141 and the second exhaust hole 142, and in fact, it is possible to achieve controlled communication of the air pump with the oxygen-enriched gas collection chamber at the first exhaust hole 141 and the second exhaust hole 142.

The suction pump may be configured to: a conduit 50 connecting the inlet end of the suction pump to the first air discharge hole 141 in the case of the first region 101 and the air conditioning requirement; in the case of the second region 102 and the air conditioning requirement, the line 50 connecting the inlet end of the suction pump to the second exhaust hole 142. This allows the oxygen-enriched gas in the oxygen-enriched gas collection chamber at the first vent 141 to be vented in the first region 101 and in the presence of a demand for air conditioning. In the case of the second region 102 and the demand for air conditioning, the oxygen-enriched gas in the oxygen-enriched gas collection chamber at the second vent 142 is vented.

The air pump 41 pumps air and exhausts the air outwards, so that the pressure of the oxygen-enriched gas collecting cavity is smaller than the pressure of the fresh-keeping space 111. That is, when the air pump 41 pumps air outwards, air in the fresh-keeping space 111 can flow to the oxygen-enriched membrane assembly 31, and part or all of oxygen in the air in the fresh-keeping space 111 enters the oxygen-enriched gas collecting cavity under the action of the oxygen-enriched membrane assembly 31, and then the fresh-keeping space 111 is discharged through the pipeline 50 and the air pump 41, so that a nitrogen-enriched and oxygen-depleted gas atmosphere beneficial to food fresh keeping is obtained in the fresh-keeping space 111.

The refrigerator 100 may further include an oxygen sensor (not shown) that may be provided at different storage areas of the fresh space 111 to detect the actual oxygen concentration of the different storage areas. And whether the air conditioning requirement exists or not can be judged according to the actual oxygen concentration of a certain storage area. For example, if the actual oxygen concentration in the first area 101 is greater than the preset concentration threshold, it may be determined that the first area 101 has an air conditioning requirement, and the oxygen concentration needs to be reduced, at this time, the pipeline switching mechanism 51 may be driven to communicate the inlet end of the air pump 41 with the pipeline 50 of the first air exhaust hole 141, and control the air pump 41 to start to operate, so as to exhaust the oxygen-enriched gas in the oxygen-enriched gas collection cavity at the first air exhaust hole 141, reduce the oxygen concentration in the first area 101, and meet the fresh-keeping requirement of the food.

The preset concentration thresholds for different storage areas within the fresh space 111 may be set to be different. In addition, a preset concentration threshold value can be determined according to the food material types stored in different storage areas. In other embodiments, in addition to determining whether the air conditioning requirement exists by acquiring the actual oxygen concentration of the storage area, the triggering operation of the user may also be directly acquired through a display device or other devices provided on the refrigerator 100. For example, after the food material to be preserved is placed into the first area 101, the user can directly control the air pump to be turned on through the display device, so as to perform controlled atmosphere preservation on the food material in the first area 101. And the specific time and the specific rotating speed for starting the air pump can be set through the display device.
