Description

Technical Field

[0001] This utility model belongs to the field of refrigerator technology, and more specifically, it relates to a refrigerator with a pull-out divider. Background Technology

[0002] In home refrigeration and food storage scenarios, it is often necessary to classify and place food of different sizes and packaging forms in the same refrigeration cavity for easy access. For example, when preparing meals or stocking up on groceries, users may want to use pull-out dividers to adjust the positions of items between shelves and manage items in an orderly manner. In this case, a refrigerator or freezer with pull-out dividers is needed to allow for partitioned placement and quick access within a limited cavity, facilitating daily use and management.

[0003] However, traditional refrigerators often lack vacuum preservation capabilities, relying solely on the low-temperature environment under normal pressure during daily storage. This makes it difficult to suppress gas exchange and moisture migration inside and outside the packaging, leading to oxidation, discoloration, and dehydration. This not only affects the taste and color of the food, shortening its shelf life, but also increases household costs due to frequent discarding and repeated purchases, thus failing to meet the stable storage needs under high-frequency use. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a refrigerator cabinet with a pull-out divider, thereby solving the technical problems of traditional refrigerator cabinets lacking vacuum preservation, being prone to oxidation and drying, and having insufficient preservation time.

[0005] The purpose and function of this utility model of a refrigerator / freezer with a pull-out divider are achieved by the following specific technical means:

[0006] A refrigerator freezer with a pull-out divider includes a cabinet body. A baffle is provided inside the cabinet body and connected to the cabinet body, dividing the interior of the cabinet body into an upper preservation layer and a lower freezing layer. Both the preservation layer and the freezing layer have doors on their outer sides. A sealing strip is embedded on one side of the cabinet body, and the door connects to the sealing strip when closed. A support frame is provided at the rear of the cabinet body, and a small vacuum pump is mounted on the support frame. A vacuum suction cup is installed inside the preservation layer, and the vacuum suction cup is connected to the small vacuum pump via a pipe.

[0007] According to a preferred embodiment, the preservation layer is provided with two sets of partitions, and two sets of slide rails are provided on both sides of the preservation layer; the two sets of partitions are slidably connected to the slide rails through sliding grooves.

[0008] According to a preferred embodiment, two sets of fixing posts are symmetrically arranged on the side of the preservation layer away from the door, and the two sets of fixing posts are connected to the corresponding mounting holes of the two sets of partitions.

[0009] According to a preferred embodiment, a lighting lamp is provided at the top of the preservation layer, and a photoelectric sensor is embedded on the left side of the preservation layer; the photoelectric sensor is electrically connected to the lighting lamp.

[0010] According to a preferred embodiment, the bottom of the freezing layer is provided with an installation groove, and a detachable water collection box is installed in the installation groove.

[0011] According to a preferred embodiment, the preservation layer is provided with a mounting base on the box door, and the mounting base is provided with a touch screen display.

[0012] According to a preferred embodiment, the support frame is provided with a dust cover, which covers the small vacuum pump and is detachably connected to the support frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model uses a vacuum suction cup in the preservation layer, which is then evacuated by a small vacuum pump. When the door and sealing strip are closed, a partially sealed cavity is formed, providing negative pressure preservation for the food, slowing oxidation and water loss, and extending the shelf life of its flavor. The preservation layer features pull-out partitions, guided by sliding rails and grooves, and uses fixed posts and partition holes to achieve rapid adjustment and positioning between layers, allowing for easy front and rear loading and unloading without interference. The lighting is activated and deactivated by a photoelectric sensor, turning on when the door is opened and off when it is closed, reducing energy consumption. The freezing layer has a removable water collection box for centralized collection of defrost condensate, which can be easily emptied by pulling it out, keeping the inner wall of the cabinet cleaner. A dust cover is added to the support frame to protect the vacuum pump, reducing dust entry and facilitating maintenance.

[0015] 2. When using this device, the vacuuming time and preservation mode can be selected via the touch screen. The vacuum pump evacuates the preservation layer, and the sealing strip ensures that the cavity maintains negative pressure. The partition can be pulled along the slide rail to make the layer height fine-tuned. After positioning, it cooperates with the fixed column to achieve load-bearing capacity, adapting to food of different sizes and packaging shapes. When the door is opened, the photoelectric sensor triggers the lighting to improve the visibility of taking out and putting in food. When routine maintenance is required, the water collection box can be pulled out from the freezer layer for emptying and cleaning. The vacuum pump and pipeline can be checked after the dust cover is quickly removed. The whole machine can maintain stable preservation effect and convenient use even under frequent opening and closing and high-load storage scenarios. Attached Figure Description

When taking out or putting in food, the pump can be turned off and the vacuum suction cups 17 can be released.

[0026] It should be noted that the small vacuum pump 16 can be an oil-free small vacuum pump of model PVD-N100V to provide a stable vacuum for the vacuum chuck 17.

[0027] The preservation layer is equipped with two sets of partitions 18, and two sets of slide rails 19 are provided on both sides of the preservation layer; the two sets of partitions 18 are slidably connected to the slide rails 19 through sliding grooves.

[0028] Specifically, the slide rails 19 are arranged in pairs along the left and right side walls of the preservation layer, with two sets on each side staggered in the upper and lower positions to form multiple height levels; the partition 18 has sliding grooves on both sides that match the slide rails 19, and can be inserted in the front and back direction during assembly to achieve sliding guidance; the partition 18 can be moved or pulled out for cleaning between different height levels as needed, and after being inserted into place, the front end can be stopped by a limiting tongue or the front edge to prevent accidental slippage.

[0029] Two sets of fixing posts 21 are symmetrically arranged on the side of the preservation layer away from the door 13. The two sets of fixing posts 21 are connected to the corresponding mounting holes of the two sets of partitions 18.

[0030] Specifically, the fixing posts 21 are distributed on the left and right sides of the rear of the preservation layer, and positioning holes are opened on the front side of the posts; the rear edge of the partition 18 is opened with corresponding installation holes, and is connected to the fixing posts 21 by screws or pins to form secondary positioning and support at the rear end, reducing sagging and shaking when lifting heavy food; when it needs to be replaced, the rear edge connector can be loosened to reposition it on the slide rail 19.

[0031] A light 22 is provided at the top of the preservation layer, and a photoelectric sensor 23 is embedded on the left side of the preservation layer; the photoelectric sensor 23 is electrically connected to the light 22.

[0032] Specifically, the lighting 22 is embedded in the light trough at the top of the preservation layer in the form of a strip light group, and the power cord is led to the electrical cavity through the rear wiring channel; the photoelectric sensor 23 is arranged inside the left door frame of the preservation layer. When the door 13 is opened, it outputs a signal to drive the lighting 22 to light up. After the door 13 is closed or the set illuminance is reached, it is turned off after a delay, so as to facilitate loading and unloading and reduce energy consumption.

[0033] It should be noted that the photoelectric sensor 23 can be an E3Z-LS61 model diffuse reflection photoelectric sensor to realize the function of detecting the opening and closing status of the door 13 and the linkage control of illumination sensing.

[0034] The bottom of the freezing layer is provided with an installation groove 24, and a detachable water collection box 25 is installed in the installation groove 24.

[0035] Specifically, the mounting groove 24 is a recessed cavity with a pull-out notch at the front end; the water collection box 25 is slidably installed in the mounting groove 24 to collect defrost or condensation water, and can be pulled out from the front for emptying and cleaning when full; the bottom surface of the mounting groove 24 can be provided with a slight slope to reduce water accumulation.

[0036] The preservation layer is provided with a mounting base 26 on the door 13, and a touch screen display 27 is provided on the mounting base 26.

[0037] Specifically, the mounting base 26 is embedded in the line-of-sight area of ​​the outer surface of the cabinet door 13, serving as the mounting base for the touch display screen 27. The touch display screen 27 is connected to the control board through an internal wiring harness and is used to set the working mode and temperature of the freshness layer and the freezing layer, and can display the operating status of the small vacuum pump 16 and the lighting lamp 22.

[0038] The support frame 15 is equipped with a dust cover 28, which covers the small vacuum pump 16 and is detachably connected to the support frame 15.

[0039] Specifically, the dust cover 28 is attached to the support frame 15 by means of clips and screws, and has heat dissipation and maintenance windows on the outside. The cover also serves to protect against dust and splashes of water. During maintenance, the dust cover 28 can be opened by loosening the clips to inspect or replace the small vacuum pump 16 and pipelines.

[0040] The specific usage and function of this embodiment are as follows:

[0041] Before use, insert the partition 18 into the corresponding height setting of the slide rail 19 according to the size of the food, and position it at the rear edge using the fixing post 21. After closing the door 13, press the sealing strip 14 against the door to form a sealed boundary. When bagged or easily rolling food needs to be placed stably in the fresh-keeping layer, turn on the small vacuum pump 16 to allow the vacuum suction cup 17 to adhere to the food surface and reduce displacement. When the door 13 is opened, the photoelectric sensor 23 triggers the lighting 22 to illuminate, making it easy to observe and place food. During the operation of the freezer layer, defrost condensate flows from the bottom into the mounting groove 24 and is collected in the removable water collection box 25, which can be removed and cleaned periodically. The touch screen 27 is used to set the temperature zone and view the operating status. During maintenance, the dust cover 28 can be opened to clean and inspect the small vacuum pump 16 and the pipeline. The whole machine achieves partitioned storage and daily maintenance of the fresh-keeping layer and the freezer layer through a combination of layered structure, adjustable slide rail 19, suction cup auxiliary positioning, lighting linkage, and removable water collection.
