[0046] Figure 1 and Figure 2 are respectively schematic structural views of a refrigerating and freezing device according to an embodiment of the present invention. As those skilled in the art can recognize, Figure 1 shows the front perspective of the refrigerating and freezing device, Figure 2 shows the rear perspective of the refrigerating and freezing device, and in Figure 1 and Figure 2 the refrigerating and freezing devices shown, in order to show an embodiment of the present invention, components such as the door body of the refrigerating and freezing device are not shown. As Figure 1 and Figure 2 shown, and referring to Figures 3 to 7, embodiments of the present invention provide a refrigeration and freezing device, including a box body 20, a gas modulation film assembly, and an air extraction pump assembly 30. An air-modulated fresh-keeping space 25 is provided inside the box body 20. The air extraction pump assembly 30 and the gas modulation film assembly are installed in the box body 20. The air extraction pump assembly 30 is communicated with the air-modulated fresh-keeping space 25 via the gas modulation film assembly to exhaust more oxygen than nitrogen in the gas of the air-modulated fresh-keeping space 25 to the outside of the air-modulated fresh-keeping space 25. The air-modulated fresh-keeping space 25 can be a closed space or an approximately closed space.

[0047] For example, a first storage compartment 24, a second storage compartment, and a compressor compartment are further provided inside the box body 20. The second storage compartment is arranged below the first storage compartment 24, and the compressor compartment is arranged at the lower rear of the second storage compartment. The air-modulated fresh-keeping space 25 can be arranged at the bottom of the first storage compartment 24. The air extraction pump assembly 30 is arranged at the rear of the air-modulated fresh-keeping space 25. The first storage compartment 24 is a refrigerating compartment, and the second storage compartment is a freezing compartment. Further, the box body 20 further includes a storage container 26 with a forward opening, and a drawer installed inside the storage container 26. The space inside the drawer is the above-mentioned air-modulated fresh-keeping space 25.

[0048] Specifically, as Figure 5 shown, the air extraction pump assembly 30 may include an air pump box 31, a plurality of mounting posts, a plurality of shock pads 32, a support plate 33, and an air extraction pump 34. The air pump box 31 is installed on the box body 20, and the air pump box 31 has an open box body 311. The open box body 311 has a placement wall at the lower side and extending in the horizontal direction. For example, if the opening of the open box body 311 faces forward or backward, one side wall of the open box body 311 is the placement wall. A plurality of mounting posts are arranged on the placement wall of the open box body 311. Optionally, the placement wall can also be arranged inside the open box body 311 and can be spaced from the box body wall of the open box body 311 parallel to the placement wall. Each shock pad 32 is sleeved on a mounting post. The support plate 33 is installed on the plurality of shock pads 32. For example, both the mounting posts and the shock pads 32 are four and are arranged at the four corners of the support plate 33. The air extraction pump 34 is installed on the upper side of the support plate 33, and the air extraction pump 34 is spaced from each wall body of the open box body 311. The air inlet of the air extraction pump 34 is communicated with the gas modulation film assembly. It can reduce the vibration and noise when the air extraction pump 34 works, and improve the stability of the air extraction pump 34 and the user experience.

[0049] The refrigeration and freezing device in the embodiments of the present invention has an air pump box 31, and the air extraction pump 34 is installed on the air pump box 31 through a special structure and is spaced from the air pump box 31, significantly reducing the noise generated by the air extraction pump 34 itself during operation, and reducing the outward propagation of the operating noise of the air extraction pump 34, such as reducing the vibration of the air extraction pump 34 transmitted to the box body 20, thereby reducing the noise during the air-modulated fresh-keeping process and the noise of the refrigeration and freezing device.

[0050] In some embodiments of the present invention, such asFigure 5 and Figure 6 As shown in Figure 6 , each shock absorber pad 32 has an upper elastomer, a lower elastomer, and a connecting elastomer connecting the upper elastomer and the lower elastomer. The outer diameter of the peripheral wall of the connecting elastomer is smaller than the outer diameter of the peripheral wall of the lower elastomer. And the outer diameter of the peripheral wall of the connecting elastomer is smaller than the outer diameter of the peripheral wall of the upper elastomer. The support plate 33 has a plurality of mounting holes, each connecting elastomer is mounted in one mounting hole, and both the upper elastomer and the lower elastomer are in contact with and abutted against the support plate 33.

[0051] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, each shock absorber pad 32 has a plurality of first through holes 321, and the plurality of first through holes are uniformly arranged along the circumferential direction of the corresponding mounting post. Both the upper surface and the lower surface of each shock absorber pad 32 have a plurality of protrusions 322, and the plurality of protrusions 322 are uniformly arranged along the circumferential direction of the corresponding mounting post. Each shock absorber pad 32 can be a rubber pad. The open box body 311 can be a plastic box. The mounting posts provided on the open box body 311 are for positioning. The air extraction pump 34 is positioned in the up and down direction by the weight of the air extraction pump 34 itself and the extrusion between the mounting posts and the shock absorber pad 32. The vacuum pump only contacts the open box body 311 through 4 shock absorber pads 32. There are gaps all around, which is beneficial to preventing vibration transmission.

[0052] In some optional embodiments of the present invention, both the upper elastomer and the lower elastomer include an inner column portion, an annular connecting plate portion, and an outer ring support portion. The inner column portion is sleeved on the mounting post. The annular connecting plate portion is connected to the inner column portion and is in contact with and abutted against the support plate 33. The outer ring support portion extends from the outer edge of the annular connecting plate portion in a direction away from the support plate 33, and the end surface of the outer ring support portion can be flush with the end surface of the corresponding inner column portion.

[0053] In some embodiments of the present invention, as Figure 5 and Figure 6 shown, the air extraction pump 34 is spaced from the upper surface of the support plate 33. For example, the air extraction pump 34 is mounted on the support plate 33 through two vertical plates 35. Further, the support plate 33 is provided with second through holes. The two vertical plates 35 are arranged in parallel and are respectively formed by extending upward from the two hole edges of the relatively arranged two holes of the second through holes. The support plate 33 and the vertical plates 35 are integrally formed and can be sheet metal parts.

[0054] To further reduce noise, the air pump box 31 further includes a box cover 312, which is disposed at the opening of the open box body 311. A sealing gasket is provided between the box cover 312 and the open box body 311. It is used to enclose the open box body 311, so that the air extraction pump 34 is in a closed environment, reducing the noise generated when the air extraction pump 34 works. In some alternative embodiments, the open box body is a first open box body, and the air pump box further includes a second open box body and a box cover. The first open box body is mounted on the second open box body through four rubber pads, and the opening of the first open box body faces the bottom wall of the second open box body. The box cover is mounted on the second open box body. In some embodiments of the present invention, a box cover is also provided at the opening of the first open box body.

[0055] In some embodiments of the present invention, the box body 20 further has a first inner liner 21 and a second inner liner. A first storage compartment 24 and a second storage compartment are respectively defined within the first inner liner 21 and the second inner liner. As Figure 3 shown, the bottom of the rear wall of the first inner liner 21 has a mounting through hole 211. The opening of the open box body 311 faces forward and is mounted in the mounting through hole 211. The outside of the open box body 311 is a foaming layer. During installation, the open box body 311 can be first installed at the mounting through hole 211, and then foaming is carried out to form a pre-embedded box. Disposing the open box body 311 to extend into the foaming layer after being set in the installation opening can not only save the space of the refrigeration and freezing device, but also greatly reduce the noise generated by the air extraction pump 34 by using the sound insulation effect of the open box body 311 itself and the sound insulation effect of the foaming layer, and prevent the transmission of the suction sound and the exhaust sound. It also isolates the noise transmission to the rear panel. Since the large plane of the rear panel can be equivalent to a vibration amplifier, after isolation, the rear panel will not cause vibration amplification, and thus no noise will be generated due to vibration.

[0056] Further, an opening is provided on the upper box wall of the open box body 311 for mounting the power supply 36 of the air extraction pump 34, and the power supply 36 is used to supply electrical energy to the air extraction pump 34.

[0057] In some embodiments of the present invention, the central area of the rear part of the first inner liner 21 is recessed backward, which can form the air duct of the refrigeration and freezing device. The open box body 311 is disposed in the outer area of the air duct and is located at the lower right side of the air duct, so that the open box body 311 does not occupy the storage space and the air duct position of the refrigeration and freezing device, so as to achieve full utilization of space.

[0058] In some embodiments of the present invention, an air extraction connection part for connecting the inside and outside of the open box body 311 is provided on the box wall of the open box body 311. The end of the air extraction connection part located inside the open box body 311 is connected to the air extraction port of the air extraction pump 34. Moreover, the refrigeration and freezing device further includes an air extraction pipe 37, whose first end is connected to the end of the air extraction connection part located outside the open box body 311, extends through the foaming layer, and its second end is connected to the interface 23 of the first inner container 21 leading to the controlled atmosphere storage space. The air extraction pipe 37 passing through the foaming layer utilizes the sound insulation effect of the foaming layer to reduce the noise during the air extraction process.

[0059] An exhaust connection part for connecting the inside and outside of the open box body 311 is also provided on the box wall of the open box body 311. The end of the exhaust connection part located inside the open box body 311 is connected to the exhaust port of the air extraction pump 34. Moreover, the refrigeration and freezing device further includes an exhaust pipe 38, whose first end is connected to the end of the exhaust connection part located outside the open box body 311, extends through the foaming layer, and reduces the noise during the exhaust process through the sound insulation effect of the foaming layer, and its second end leads to the compressor compartment of the refrigeration and freezing device.

[0060] In some embodiments of the present invention, at least part of the exhaust pipe 38 is arranged side by side with at least part of the drain pipe 22 for draining the rear duct of the first storage compartment 24 of the refrigeration and freezing device, so that the exhaust pipe 38 is guided by the drain pipe 22, which is convenient for installation and fixation, avoids the position deviation of the exhaust pipe 38 caused by long-term use, discharges the oxygen-rich gas into the compressor compartment of the refrigeration and freezing device, and avoids setting another pipeline in the foaming layer, reducing the heat preservation performance of the foaming layer. For example, the exhaust pipe 38 can be tied to the drain pipe 22 or structures such as through-rings are provided on the outer wall of the drain pipe 22, so that the exhaust pipe 38 can be guided by the drain pipe 22 to discharge the gas into the compressor compartment.

[0061] In this embodiment, the parts of the air extraction pipe 37 and the exhaust pipe 38 of the air extraction pump 34 located outside the open box body 311 pass through the foaming layer, which can effectively reduce the noise during the air intake process and the exhaust process. At least part of the exhaust pipe 38 is arranged side by side with at least part of the drain pipe 22 of the refrigeration and freezing device to discharge the oxygen-rich gas into the compressor compartment of the refrigeration and freezing device. This setting of the exhaust pipe 38 is beneficial to the installation and fixation of the exhaust pipe 38, avoids the position change of the exhaust pipe 38 caused by long-term use, and avoids setting another pipeline in the foaming layer, reducing the heat preservation effect of the foaming layer.

[0062] In some embodiments of the present invention, the storage container 26 may include a receiving cavity and an ion generating device. Of course, a receiving cavity may also be defined at other positions or structures within the box body 20. The receiving cavity is in communication with the controlled atmosphere fresh-keeping space 25 to enable gas to flow between the controlled atmosphere fresh-keeping space 25 and the receiving cavity. The controlled atmosphere film assembly is disposed within the receiving cavity. The ion generating device is configured to be excited to ionize the gas within the receiving cavity to generate deodorizing and bactericidal substances, and the deodorizing and bactericidal substances flow with the gas to sterilize or deodorize the receiving cavity and / or the controlled atmosphere fresh-keeping space 25. The deodorizing and bactericidal substances flow with the gas to sterilize or deodorize the receiving cavity and / or the controlled atmosphere fresh-keeping space 25. For example, the ion generating device changes water vapor and oxygen into ions with strong oxidation ability. After sufficient circulation, the mold substances in the controlled atmosphere fresh-keeping space 25 will be removed, greatly improving the efficiency of controlled atmosphere and the fresh-keeping period, and more comprehensively maintaining the taste of fruits and vegetables.

[0063] In some embodiments of the present invention, the refrigeration and freezing device includes a blower. There is a first ventilation structure and a second ventilation structure between the receiving cavity and the controlled atmosphere fresh-keeping space 25 to communicate the receiving cavity and the controlled atmosphere fresh-keeping space 25 at different positions respectively. The blower is configured to cause the gas in the controlled atmosphere fresh-keeping space 25 to return to the controlled atmosphere fresh-keeping space 25 sequentially via the first ventilation structure, the receiving cavity, and the second ventilation structure. Further, a diversion air duct is provided between the blower and the controlled atmosphere film assembly to cause the gas flowing out of the blower to flow towards the controlled atmosphere film assembly. And an opening is provided on the duct wall of the diversion air duct. The ion generating part of the ion generating device is disposed at the opening. The control part of the ion generating device is disposed within the receiving cavity and is outside the diversion air duct, and the duct wall prevents the gas entering the receiving cavity from flowing towards the control part. It can prevent the cooling gas or high-humidity environment from damaging and invalidating the control part, especially preventing the moisture in the cooling gas from entering the control part. The control part also does not occupy the space of the diversion air duct, and the air supply is smooth. The first ventilation structure includes at least one first ventilation hole, and the second ventilation structure includes at least one second ventilation hole. At least one first ventilation hole and at least one second ventilation hole are provided in the partition wall between the receiving cavity and the controlled atmosphere fresh-keeping space 25.

The ion generator may include a first electrode and a second electrode connected to the control unit, with a discharge gap defined between the first and second electrodes. The discharge gap is configured to be broken down by the first voltage to ionize surrounding gas. Furthermore, the first and second electrodes are isolated and generate heat at the second voltage. The control unit and the ion generator may be connected via a cable.
