Description

Technical Field

[0001] This utility model relates to the field of food preservation refrigerator technology, specifically a vacuum humidity preservation refrigerator. Background Technology

[0002] A fresh-keeping refrigerator is a type of refrigerator that maintains a constant low temperature. Compared to ordinary refrigerators, it can provide people with better food preservation and a healthier life by creating a low-vacuum, oxygen-deficient, and dry environment inside the refrigerator, which can effectively inhibit the growth of fungi and bacteria, thus extending the freshness of food and reducing the risk of food freezing damage.

[0003] Publication No. CN2527937Y discloses a low-vacuum preservation refrigerator or freezer, which uses a vacuum pump or exhaust fan to extract the air inside the box, creating a low-vacuum, oxygen-deficient, and dry environment. This effectively inhibits the growth of fungi and bacteria, thus extending the freshness of food and increasing the refrigeration temperature of food, thereby reducing the risk of food freezing damage or frostbite.

[0004] However, the vacuum preservation refrigerators mentioned above still have the following problems in actual use: Although a vacuum environment is achieved inside the refrigerator through the built-in vacuum pump, the external operation of the refrigerator cannot be synchronized. The refrigerator door, which is responsible for creating a sealed vacuum environment, is opened and closed only by magnetic attraction. However, magnetic attraction cannot be effectively connected in a vacuum state. At the same time, the vacuum mechanism works continuously and cannot be adjusted automatically according to the usage of the refrigerator, which can easily lead to increased energy consumption.

[0005] Therefore, we proposed a vacuum humidity-controlled refrigerator to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum constant humidity preservation refrigerator to solve the problems mentioned in the background technology. Although the current refrigerator achieves a vacuum environment inside the refrigerator through a built-in vacuum pump, it cannot synchronize the external operation of the preservation refrigerator. The refrigerator door, which is used to achieve a sealed vacuum environment, is opened and closed only by magnetic attraction. However, magnetic attraction cannot be effectively connected in a vacuum state. At the same time, the vacuum mechanism works continuously and cannot be adjusted automatically according to the use of the refrigerator, which can easily lead to increased energy consumption.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vacuum constant humidity preservation refrigerator, including a refrigerator body and preservation cavities opened on the upper and lower sides inside the refrigerator body;

[0008] The front of the refrigerator body is hinged to the left end of the lockable door on both the top and bottom sides, and locking limiters are fixedly installed on the top and bottom sides of the right end of the lockable door on both sides; it also includes:

[0009] An anti-detachment mechanism is provided on the front right side of the refrigerator body, and the anti-detachment mechanism includes an anti-detachment limiter. The upper and lower sides of the anti-detachment limiter are rotatably provided with guide shafts through bearings.

[0010] A vacuum humidity sensor is fixedly installed on the right rear side of the refrigerator body, and vacuum humidity panels are fixedly installed on the left and right sides of the interior of the upper and lower sides of the refrigerator body's preservation chamber.

[0011] Preferably, the overall body of the refrigerator is arranged in a vertical rectangular structure, and the hinged locking doors on the upper and lower sides of the front of the refrigerator body are used to seal and protect the opened preservation cavity. The locking limiters on the upper and lower sides of the right end of the locking door are installed in pairs and slidably installed inside the anti-detachment limiter.

[0012] Preferably, the anti-detachment mechanism includes an anti-detachment limiter that is fixedly installed on the front right side of the refrigerator body, and the left end of the anti-detachment limiter is symmetrically provided with anti-detachment guide grooves, and the symmetrically provided anti-detachment guide grooves are distributed one-to-one with the locking limiter on the right end of the locking door.

[0013] Preferably, the anti-detachment mechanism includes anti-detachment gears, which are fixedly installed on the outer wall of the guide shaft in an up-down distribution manner. The tooth spacing of the anti-detachment gears is greater than the thickness of the locking limiter, and the symmetrically distributed locking limiters mesh with the anti-detachment gears.

[0014] Preferably, the anti-detachment mechanism includes a locking groove wheel, which is fixedly installed at the center of the upper and lower guide shafts inside the anti-detachment limiter. Furthermore, the upper and lower right ends of the anti-detachment limiter are slidably provided with abutment unlockers, and the left ends of the upper and lower abutment unlockers are engaged with the slots opened inside the locking groove wheel.

[0015] Preferably, the symmetrically arranged locking unlocker and anti-detachment limiter are connected to each other by a reset spring, and the outer sides of the upper and lower locking unlockers are both inclined structures. The inclined shape of the outer side of the locking unlocker allows the locking groove wheel to rotate freely in the clockwise direction, and the locking unlocker and anti-detachment limiter are engaged with each other in the initial state.

[0016] Preferably, the anti-detachment mechanism includes a drive rack, which is slidably disposed on the upper and lower sides inside the anti-detachment limiter, and the drive racks on the upper and lower sides are meshed with the locking groove wheel. Moreover, the rear ends of the drive racks on the upper and lower sides are connected to the on / off switch of the vacuum humidifier.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This vacuum humidity preservation refrigerator, through the anti-detachment limiter set on the right side of the refrigerator body, locks the locking door to ensure that the locking door will not be incompletely closed or pop out due to varying closing force, and also drives the corresponding vacuum humidity panel to work, thereby reducing energy consumption. The specific details are as follows:

[0018] 1. By engaging the locking limiter at the end of the locking door with the locking groove wheel on the outer wall of the guide shaft, the locking groove wheel is locked to the unlocking device in the initial state. This ensures that the guide shaft can only rotate when the locking limiter and the anti-detachment limiter are combined, preventing pop-out during the combination and thus improving the sealing effect of the refrigerator body.

[0019] 2. The locking doors and locking limiters on both the upper and lower sides, which are in the closed state, drive the rotating locking groove wheel to move the meshing drive rack backward, thereby causing the drive rack to drive the on / off switch to work, so as to drive the vacuum humidifier and the vacuum humidifier panel set inside the preservation chamber to work.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] Example 1: In order to solve the problem that the existing refrigerator body 1 cannot be effectively sealed, this example adopts the following technical solution: by engaging the locking limiter 4 at the end of the locking door 3 with the locking groove wheel 11 on the outer wall of the guide shaft 6, the locking groove wheel 11 in the initial state is locked with the unlocking device 12, so that the guide shaft 6 can only rotate when the locking limiter 4 and the anti-detachment limiter 5 are combined, avoiding the situation of popping out when combined, thereby improving the sealing effect of the refrigerator body 1.

[0030] A vacuum constant humidity preservation refrigerator includes a refrigerator body 1 and preservation cavities 2 opened on the upper and lower sides inside the refrigerator body 1; the upper and lower sides of the front of the refrigerator body 1 are hinged to the left end of the lockable door 3, and the upper and lower sides of the right end of the lockable door 3 are fixedly provided with locking limiters 4; an anti-detachment mechanism is provided on the front right side of the refrigerator body 1, and the anti-detachment mechanism includes an anti-detachment limiter 5, and the upper and lower sides of the anti-detachment limiter 5 are rotatably provided with guide shafts 6 through bearings.

[0031] The overall refrigerator body 1 is arranged in a vertical rectangular structure. The hinged locking doors 3 on the upper and lower sides of the front of the refrigerator body 1 are used to seal and protect the opening of the preservation cavity 2. The locking limiters 4 on the upper and lower right sides of the locking door 3 are installed in pairs and slidably installed inside the anti-detachment limiter 5. The anti-detachment mechanism includes the anti-detachment limiter 5, which is fixedly installed on the front right side of the refrigerator body 1. The left end of the anti-detachment limiter 5 is symmetrically provided with anti-detachment guide grooves 9. The symmetrically provided anti-detachment guide grooves 9 are distributed one-to-one with the locking limiters 4 on the right side of the locking door 3.

[0032] like Figures 1-2As shown, the food to be kept fresh and kept at a constant humidity is placed in the freshness cavities 2 opened on the upper and lower sides of the refrigerator body 1. Then, the locking door 3, which is hinged to the refrigerator body 1, is rotated counterclockwise so that the locking door 3 can close the freshness cavity 2. Then, the locking limiters 4, which are symmetrically installed on the upper and lower sides of the right end of the locking door 3, are flipped and then enter the interior of the anti-detachment limiter 5 through the anti-detachment guide groove 9.

[0033] The anti-detachment mechanism includes an anti-detachment gear 10, which is fixedly installed on the outer wall of the guide shaft 6 in an up-down distribution manner. The tooth spacing of the anti-detachment gear 10 is greater than the thickness of the locking limiter 4, and the symmetrically distributed locking limiters 4 and anti-detachment gear 10 mesh with each other. The anti-detachment mechanism includes a locking groove wheel 11, which is fixedly installed at the center position of the guide shaft 6 on both the upper and lower sides inside the anti-detachment limiter 5. The upper and lower sides of the right end of the anti-detachment limiter 5 are slidably provided with abutment unlockers 12, and the left ends of the upper and lower sides of the abutment unlockers 12 are engaged in the slots opened inside the locking groove wheel 11.

[0034] The symmetrically arranged contact unlocker 12 and the anti-disengagement limiter 5 are connected to each other by a return spring 13. The outer sides of the contact unlocker 12 at both ends are inclined. The inclined shape of the outer side of the contact unlocker 12 allows the locking groove wheel 11 to rotate freely in the clockwise direction. In the initial state, the contact unlocker 12 and the anti-disengagement limiter 5 are engaged with each other.

[0035] like Figures 4-6 As shown, the locking limiter 4, which enters the anti-detachment limiter 5, first contacts the teeth of the anti-detachment gear 10. The guide shaft 6, which is fixed to it, is fixedly connected to the locking groove wheel 11. The groove of the locking groove wheel 11 is abutted by the abutting unlocker 12. When the locking limiter 4 drives the guide shaft 6 and the locking groove wheel 11 to rotate clockwise, the inclined structure at the inner end of the abutting unlocker 12 prevents the abutting unlocker 12 from limiting the clockwise rotation of the locking groove wheel 11, the guide shaft 6, and the anti-detachment gear 10. This means that the locking door 3 is not obstructed when closing, which can help the refrigerator body 1 improve the vacuum preservation effect.

[0036] When it is necessary to open the locking door 3, manually pull the sliding unlocking device 12, which is installed inside the anti-disengagement limiter 5, to the right, so that its inner end is disengaged from the locking groove wheel 11. At this time, the guide shaft 6 and the anti-disengagement gear 10 are in a state of free rotation. Then pull the locking door 3 outward, thereby causing the locking limiter 4 to disengage from the anti-disengagement gear 10, so as to ensure that the locking door 3 will not be incompletely closed or pop out due to the amount of closing force.

[0037] Example 2: In order to solve the problem that the vacuum humidifier 7 of the existing refrigerator body 1 is always in working state, this example adopts the following technical solution: the locking door 3 and the locking limiter 4 on the upper and lower sides are closed, which drives the rotating locking groove wheel 11 to drive the meshing drive rack 14 to move backward, thereby causing the drive rack 14 to drive the on / off switch to work, so as to drive the vacuum humidifier 7 and the vacuum humidifier panel 8 set inside the freshness preservation cavity 2 to work.

[0038] Among them, a vacuum humidifier 7 is fixedly installed on the right rear side of the refrigerator body 1, and vacuum humidifier panels 8 are fixedly installed on the left and right sides of the interior of the upper and lower sides of the freshness chamber 2 of the refrigerator body 1; the anti-detachment mechanism includes a drive rack 14, and the drive rack 14 is slidably installed on the upper and lower sides of the interior of the anti-detachment limiter 5, and the drive rack 14 on the upper and lower sides is meshed with the locking groove wheel 11, and the rear end of the drive rack 14 on the upper and lower sides is connected to the on / off switch of the vacuum humidifier 7.

[0039] like Figures 1-2 , Figure 6 As shown, when the upper and lower locking doors 3 are closed, the locking limiter 4 drives the anti-detachment gear 10 and the guide shaft 6 to rotate during movement. The guide shaft 6 drives the locking groove wheel 11 and the meshing drive rack 14 to move backward, so that the drive rack 14 drives the on / off switch inside the vacuum humidifier 7 to form a circuit, so that the vacuum humidifier 7 can work through the vacuum humidifier 7 set inside the preservation chamber 2. When any locking door 3 is open, the locking limiter 4 drives the guide shaft 6 to rotate in the opposite direction, and then the rotating locking groove wheel 11 drives the drive rack 14 to move forward, so as to close the corresponding on / off switch, so that the vacuum humidifier 7 inside the preservation chamber 2 in the open state stops working, reducing working energy consumption.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
