Background

Fresh fruits and vegetables need a low-temperature and high-humidity storage environment (the relative humidity is 75-99%).

The reason for the humidity reduction in the refrigerator is that during the cooling process of the compressor, after the hot air in the refrigerator passes through the evaporator, the moisture in the air condenses on the surface of the evaporator to form frost.

Referring to fig. 1 to 3, a refrigerating and freezing apparatus 1 of the present invention includes a box body 10, an atomizing chamber 31, and a first lifting mechanism.

The housing 10 defines a storage compartment 11 for storing articles therein and a unit compartment 12 at the bottom of the housing 10, the storage compartment 11 and the unit compartment 12 being separated by a partition plate assembly 40, that is, the storage compartment 11 is adjacently disposed above the unit compartment 12. The partition assembly 40 is provided with a first air outlet 41 and a first air return opening 42 which are communicated with the storage chamber 11.

The atomization box 31 is disposed within the unit compartment 12 and is configured to controllably provide a high humidity airflow to the storage compartment 11. The atomization box 31 has a humidifying air outlet 311 at the top thereof to allow the high-humidity air flow generated by it to flow out, and a humidifying air return 312 at the top thereof to allow the air flow to flow into the atomization box 31.

The first elevating mechanism is disposed below the atomization box 31 and is used for supporting the atomization box 31. The first lifting mechanism is configured to operatively lift the atomization box 31 and/or lower the atomization box 31, and to sealingly communicate the humidification air outlet 311 and the humidification air return 312 with the first air outlet 41 and the first air return 42, respectively, when the atomization box 31 is lifted, and to separate the atomization box 31 from the partition assembly 40 when the atomization box 31 is lowered.

Fig. 5 is a schematic diagram of a first lifting mechanism in a descending atomization box state according to an embodiment of the present invention, fig. 6 is a schematic diagram of a portion a in fig. 5, fig. 7 is a schematic diagram of a first lifting mechanism in a lifting atomization box state according to an embodiment of the present invention, and fig. 8 is a schematic diagram of a portion B in fig. 7. Referring to fig. 5 to 8, in some embodiments, the first lifting mechanism includes at least one first lifting unit 61, and the first lifting unit 61 includes a rotating shaft 611 and a jacking structure 612. The shaft 611 is configured to extend in a horizontal direction and is rotatably supported on the bottom plate 121 of the module case 12. The jacking structure 612 has a first contact surface 6121 and a second contact surface 6122 for contacting the bottom wall of the atomization box 31. The lifting structure 612 is fixedly connected with the rotating shaft 611 to rotate synchronously with the rotating shaft 611, so that the first contact surface 6121 or the second contact surface 6122 of the lifting structure faces upwards selectively and is in contact with the bottom wall of the atomization box 31. The first contact surface 6121 is located at a higher height when facing upwards than the second contact surface 6122 is located when facing upwards.

Specifically, the shaft 611 may extend in a lateral direction, a front-back direction, or other suitable horizontal direction, and may be operable to rotate about its axis. The jacking structure 612 can rotate along with the rotating shaft 611, when the jacking structure 612 rotates to enable the first contact surface 6121 of the jacking structure to contact with the bottom wall of the atomization box 31, the atomization box 31 is at a first height position, and when the atomization box 31 is at the first height position, the bottom wall of the atomization box 31 is at a height equivalent to that of the first contact surface 6121; when the lifting structure 612 rotates to make the second contact surface 6122 contact with the bottom wall of the atomization box 31, the atomization box 31 is at the second height position, and the bottom wall of the atomization box 31 is at the same height as the second contact surface 6122 when the atomization box 31 is at the second height position. Since the first contact surface 6121 is higher when facing upward than the second contact surface 6122, the height of the atomization box 31 is higher when located at the first height position than when located at the second height position, that is, the atomization box 31 is in a lifted state when located at the first height position, and the atomization box 31 is in a lowered state when located at the second height position.

Further, the height of the first contact surface 6122 is set to be at a height that the humidifying air outlet 311 and the humidifying air return 312 of the atomizing box 31 are just in sealed communication with the first air outlet 41 and the first air return 42 on the partition assembly 40, respectively, so as to avoid air leakage therebetween, thereby improving the humidifying efficiency. When the second contact surface 6122 faces upward, the height of the second contact surface 6122 is set to be such that the atomization box 31 is completely separated from the partition plate assembly 40, that is, a certain gap is formed between the atomization box 31 and the partition plate assembly 40, so as to prevent the atomization box 31 from touching the partition plate assembly 40 in the process of dismounting.

In some embodiments, the first contact surface 6121 and the second contact surface 6122 are two planes perpendicular to each other, so that the first contact surface 6121 and the bottom wall of the atomization box 31 both have a larger contact area when contacting each other, and the second contact surface 6122 and the bottom wall of the atomization box 31 both have a larger contact area when contacting each other, thereby preventing the support stability of the atomization box 31 from being affected by the occurrence of a slip phenomenon between the jacking structure 612 and the atomization box 31. Moreover, the first contact surface 6121 and the second contact surface 6122 are perpendicular to each other, so that the first contact surface 6121 and the second contact surface 6122 can be arranged adjacent to each other, the rotation angle of the rotating shaft 611 is reduced, the relative sliding distance between the jacking structure 612 and the atomization box 31 is reduced, and the operation by a user is facilitated.

Further, the first contact surface 6121 and the second contact surface 6122 are connected by a smooth arc surface 6123. The arc surface 6123 serves as a transition surface between the first contact surface 6121 and the second contact surface 6122, so that sliding friction between the jacking structure 612 and the atomization box 31 can be reduced, and the atomization box 31 can be smoothly and stably switched between a lifting state and a falling state.

Specifically, the jacking structure 612 may be a bar-shaped structural member with a U-shaped cross section, and the rotating shaft 611 is fixedly connected to an inner side wall surface of the jacking structure 612, which is far away from the first contact surface 6121. The extending direction of the jacking structure 612 is consistent with the extending direction of the rotating shaft 611, so that the first contact surface 6121 and the second contact surface 6122 of the jacking structure 612 are both strip-shaped planes, the areas of the first contact surface 6121 and the second contact surface 6122 are increased, and the supporting strength and the supporting stability of the atomization box 31 are improved.

In some embodiments, the first lifting unit 61 further includes an operating handle 613, and the operating handle 613 is fixedly connected to one end of the rotating shaft 611 to operably drive the rotating shaft 611 to rotate. The rotating shaft 611 is rotated by the operating handle 613, so that the force arm is prolonged, labor is saved, and the operation of a user is facilitated.

Further, the rotating shaft 611 may extend in a depth direction of the case 10, and one end of the operating handle 613 is fixedly connected to a front end of the rotating shaft 611, so that the operating handle 613 is located at a front side of the case 10, which is in accordance with a user's usual usage habit.

Furthermore, the front end of the rotating shaft 611 is connected with the operating handle 613 in a form-fitting manner, so that the connection is reliable and the structure is simple.

The applicant has recognized that during the process of lifting and lowering the atomization box 31 by the lifting mechanism, sliding friction exists between the atomization box 31 and the lifting structure 612, which may cause the atomization box 31 to displace in other directions than the height direction, thereby causing the air ports of the atomization box 31 to be misaligned with the air ports of the partition plate assembly 40.

For this reason, in some embodiments, two first limiting plates 122 arranged at intervals in the horizontal direction are further disposed on the bottom plate 121 of the unit cabin 12, and the two first limiting plates 122 are respectively located at two opposite outer sides of the atomization box 31, so as to limit the atomization box 31 in the arrangement direction of the two first limiting plates 122 during the lifting process of the atomization box 31, prevent the atomization box 31 from shifting in the arrangement direction of the two first limiting plates 122 during the lifting process, so that the lifting of the atomization box 31 is more stable, and thus ensure that each air port of the atomization box 31 is accurately abutted to the corresponding air port of the partition plate assembly 40.

In some embodiments, the arrangement direction of the two first limiting plates 122 is perpendicular to the extending direction of the rotating shaft 611. For example, the rotating shaft 611 extends in the depth direction of the housing 10, and the two first limiting plates 122 are arranged laterally outside the two lateral sides of the atomizing chamber 31. Therefore, when the rotating shaft 611 rotates, the direction of the sliding friction generated between the jacking structure 612 and the atomization box 31 is consistent with the direction of the blocking effect of the first limiting plate 122 on the atomization box 31, and the occurrence of play or displacement in the lifting process of the atomization box 31 can be thoroughly avoided even if no other limiting structures are arranged.

Specifically, each of the first limit plates 122 is a bar-shaped limit plate extending parallel to the rotation shaft 611 to contact the entire side wall of the atomization box 31, thereby more effectively limiting the atomization box 31.

In some embodiments, the number of the first lifting units 61 is two, two first lifting units 61 are arranged at the bottom of the atomization box 31 side by side and at intervals, and the rotating shafts 611 of the two first lifting units 61 are parallel to each other. Thereby, the atomization box 31 can be supported and lifted more smoothly by the two first lifting units 61.

Specifically, two first elevating units 61 may be supported at the bottom of both lateral sides of the atomization box 31, respectively.

In some embodiments, the refrigerating and freezing device 1 further comprises a water storage tank 32, wherein the water storage tank 32 is disposed in the unit chamber 12 and connected to the atomization tank 31 for supplying liquid water to the atomization tank 31.

The applicant has appreciated that the fluid connection between the reservoir 32 and the nebulizing chamber 31 is highly demanding with respect to tightness and requires the use of mechanical structures such as pipes, and therefore it is preferable to keep the reservoir 32 and the nebulizing chamber 31 relatively stationary without relative movement. To this end, the present invention also supports the water storage tank 32 on the first lifting mechanism, and is configured to lift synchronously with the atomization tank 31, i.e., to remain relatively stationary with the atomization tank 31. This prevents the raising and lowering operation of the atomization tank 31 from affecting the fluid connection between the water storage tank 32 and the atomization tank 31.

In some embodiments, the partition assembly 40 further defines a second air outlet 43 and a second air return 44, which are communicated with the storage compartment 11. The refrigerating and freezing apparatus 1 further includes a refrigerator group 20 and a second elevating mechanism.

The refrigeration unit 20 is disposed within the unit compartment 12 and is configured to controllably provide a cooling airflow to the storage compartment 11. That is, the refrigerator group 20 is controlled to refrigerate the storage compartment 11. The refrigerating unit 20 includes a refrigerating unit box 21, and a refrigerating air outlet 211 allowing a cooling air flow to flow out and a refrigerating air return 212 allowing an air flow to flow into the refrigerating unit box 21 are formed at the top of the refrigerating unit box 21.

The second lifting mechanism is disposed below the refrigerator group box 21 and is configured to support the refrigerator group box 21. The second lifting mechanism is configured to operatively lift the refrigeration unit case 21 and/or drop the refrigeration unit case 21, and to cause the refrigeration outlet 211 and the refrigeration return 212 to be in sealed communication with the second outlet 43 and the second return 44, respectively, when the refrigeration unit case 21 is lifted, and to cause the refrigeration unit case 21 to be separated from the partition assembly 40 when the refrigeration unit case 21 is dropped.

That is, the refrigerating unit 20 for refrigerating the storage compartment 11 is also relatively independently disposed in the unit compartment 12 and can be raised or lowered by the second elevating mechanism, and on the one hand, can be selectively brought into fluid communication with the storage compartment 11 to normally supply cold to the storage compartment 11; on the other hand, the refrigeration unit 20 can be completely separated from the partition plate assembly 40 by descending the refrigeration unit 20, so that the refrigeration unit 20 is independently disassembled and assembled on the premise of no structural interference, and the refrigeration unit 20 is convenient to overhaul.

Specifically, the refrigerating unit 20 further includes an evaporator 22, an air supply blower 23, a compressor, a condenser, a water pan, an evaporating pan, and the like, which are disposed in the refrigerating unit box 21. Since the operation of the refrigeration unit 20 is well known to those skilled in the art, it will not be described in detail herein.

In some embodiments, the second lift mechanism has the same structure as the first lift mechanism. That is, the second elevating mechanism also includes at least one second elevating unit 71, and the structure of the second elevating unit 71 is the same as that of the first elevating unit 61. The second lifting unit 71 may also include a rotating shaft, a lifting structure, an operating handle, and other structures, which are not described herein.

In some embodiments, the refrigeration-freezing apparatus 1 further comprises a control box 33, the control box 33 being configured to control the operation of the atomization box 31. Specifically, the control box 33 can control the operation of the atomization box 31 when the storage chamber 11 needs to be humidified, so as to generate a high-humidity airflow, and the high-humidity airflow is sent to the storage chamber 11, so as to achieve the purpose of humidification. When the storage compartment 11 does not need humidification, the control box 33 controls the atomization box 31 to stop running, and the atomization box 31 does not generate high-humidity airflow and has no humidification effect.

Further, the control box 33 may be supported on the second elevating mechanism to be elevated in synchronization with the refrigerator group 20. The control box 33 and the atomization box 33 are connected through a wire harness, so that even if relative movement is generated between the two, the electrical connection between the two is not affected. Specifically, the control box 33 may be located at the front side of the refrigerator unit 20, so that the cooling air outlet 211 of the refrigerator unit 20 communicates with the air supply duct 13 located at the rear side of the storage compartment 11.

Specifically, the atomization tank 31 may be provided therein with an ultrasonic atomizer for generating water mist, a humidification fan for driving the water mist to flow toward the humidification air outlet 311 to form a high humidity air flow, a water pump for pumping the water in the water storage tank 32 into the atomization tank 31, and the like.

In some embodiments, a supply air duct 13 for supplying air to the storage compartment 11 is further defined in the box 10. The air supply duct 13 may be located behind the storage compartment 11. The cooling air flow generated by the refrigerating unit 20 is sent to the storage compartment 11 through the air supply duct 13.

The applicant has recognized that the humidifying fan in the atomizing chamber 31 is low in power and driving ability, and it is difficult to efficiently deliver the mist generated therefrom to the upper region of the storage compartment 11. However, the refrigerating unit 20 is configured to deliver the cooling airflow to the storage compartment 11, and has a relatively large fan power and a relatively high driving capability, so that the high-humidity airflow generated by the atomizing box 31 can be caused to flow at a high speed by skillfully utilizing the driving and blowing of the refrigerating unit 20, and can be effectively delivered to the entire space of the storage compartment 11.

For this purpose, the first air outlet 41 of the partition plate assembly 40 may communicate with the air supply duct 13 to supply the high-humidity air flow to the air supply duct 13, so that the high-humidity air flow flows into the storage compartment 11 along with the cooling air flow. That is to say, the cooling air flow that refrigerating unit 20 produced and the high humid air flow that the fog box 31 produced carry to storing compartment 11 through same wind channel to can utilize the high-speed cooling air flow that flows in the air supply wind channel to drive high humid air flow and carry to storing compartment 11 together, compensate the weak defect of driving force of humidification fan, thereby effectively carry out the humidification to whole storing compartment 11.

Meanwhile, since the cooling air flow generated by the refrigerating unit 20 and the high-humidity air flow generated by the atomizing box 31 are delivered to the storage compartment 11 through the same air supply duct 13, the cooling air flow and the high-humidity air flow can be naturally mixed in the air supply duct 13. The air supply duct 13 can uniformly supply air to the storage compartment 11, so that high-humidity air can be uniformly diffused to the whole storage compartment 11 along with cooling air, and the aim of uniform humidification is fulfilled.

It will be appreciated by those skilled in the art that the refrigeration and freezing apparatus 1 of the present invention may be a single door refrigerator, and have only one storage compartment 11.

In other embodiments, the refrigerating and freezing device 1 may also be not limited to the refrigerator structure shown in fig. 1, and may also be a double-door refrigerator, a triple-door refrigerator, or the like, and has a plurality of storage compartments arranged up and down, wherein the storage compartment 11 is the storage compartment located at the lowest position.

In other embodiments, the refrigerator 1 may not be limited to the refrigerator structure shown in fig. 1, but may also be a refrigerator or other various refrigerating and freezing devices that utilize air cooling to refrigerate.

It should be further understood by those skilled in the art that the terms "upper", "lower", "front", "rear", "top", "bottom", etc. used in the embodiments of the present invention are used with reference to the actual usage state of the refrigerating and freezing device 1, and these terms are only used for convenience of description and understanding of the technical solution of the present invention, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore, should not be construed as limiting the present invention.
