Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of refrigerators, and particularly relates to a double-evaporator refrigerator. BACKGROUND

[0002] The refrigerator is also called a cold cabinet, which is a device for storing food and other items at low temperature. The existing refrigerator is mainly divided into a single-evaporator refrigerator and a double-evaporator refrigerator. The double-evaporator refrigerator actually has two sets of refrigeration systems, two evaporators (one for the refrigeration chamber and one for the freezer chamber), and two fans. Whether it is the refrigeration chamber or the freezer chamber, only one set of system works when the temperature is insufficient. In this way, the refrigeration efficiency is faster and more energy-saving. Compared with the single-evaporator refrigerator, the double-evaporator refrigerator has the advantage that the refrigeration chamber and the freezer chamber are not in the same circulation system, thereby perfectly solving the problem of odor circulation between the two chambers.

[0003] The existing refrigerator is generally provided with a drawer for storing food in the freezer chamber. When in use, the drawer can be pulled out a distance from the freezer chamber, so as to conveniently put food into the drawer or take food out of the drawer. However, during the process of pushing the drawer back into the freezer chamber, the drawer may sometimes not be completely pushed into the freezer chamber, so that when the cabinet door is closed, the cabinet door will be blocked by the drawer, so that the cabinet door cannot be completely closed, thereby causing the loss of cold air and affecting the refrigeration effect of the refrigerator.

[0004] Therefore, it is necessary to invent a double-evaporator refrigerator to solve the above problems. SUMMARY

[0005] In view of the above problems, the present application provides a double-evaporator refrigerator to solve the problems in the background art.

[0006] To achieve the above purpose, the present application provides the following technical scheme: a double-evaporator refrigerator, comprising a cabinet body, a refrigeration area and a freezing area are arranged in the cabinet body, and a partition plate is horizontally and fixedly connected between the refrigeration area and the freezing area, a plurality of storage areas are arranged in the freezing area, and a refrigeration coil is horizontally and detachably arranged between two adjacent storage areas, a drawer is arranged in the storage area, a plurality of grooves are formed in the inner wall of the cabinet body corresponding to the two sides of the drawer, a reset device for assisting the drawer to reset is arranged in the grooves, a plurality of supporting plates are horizontally and detachably arranged in the refrigeration area, and the refrigeration area is evenly divided by the supporting plates, cabinet doors are arranged on the front sides of the refrigeration area and the freezing area, and the cabinet doors and the front side edges of the cabinet body are hinged together.

[0007] In the process of pushing the drawer back into the cabinet body, when the drawer contacts the plurality of reset devices on the inner walls of both sides of the freezing area, as the drawer is continuously pushed, the reset devices can be deflected under the driving of the drawer. When the reset devices are deflected by a certain angle, the reset devices can automatically completely receive the drawer into the cabinet body, so as to ensure that the cabinet door can be tightly fitted with the cabinet body when the cabinet door is closed, avoid the loss of cold air due to the closing of the cabinet door, and ensure the freezing effect of the freezing area on the food in the drawer.

[0008] Further, the reset device comprises a V-shaped plate, the opening angle of the V-shaped plate is less than ninety degrees, and the V-shaped plate is completely located in the groove. A fixed shaft is fixedly connected to the side of the V-shaped plate away from the drawer, and the fixed shaft is located at the intersection of the two edges of the V-shaped plate. The fixed shaft is vertically connected to the side wall of the groove. Positioning blocks are symmetrically arranged at the bottom of the fixed shaft. The positioning blocks are fixedly connected to the side wall of the groove. A V-shaped clamping groove matching the shape of the V-shaped plate is formed on the side of the V-shaped plate close to the drawer. An activity rod is vertically inserted into the V-shaped clamping groove. A connecting plate is vertically connected to the end of the activity rod close to the drawer. A first hanging rod is vertically fixedly connected to the bottom end of the connecting plate away from the drawer. A first hanging ring is rotatably sleeved on the first hanging rod. A second hanging rod is vertically fixedly connected below the fixed shaft. A second hanging ring is rotatably sleeved on the second hanging rod. A spring is fixedly connected between the second hanging ring and the first hanging ring, and the spring is always in a stretched state. A baffle matching the shape of the V-shaped plate is arranged on the side of the V-shaped plate close to the drawer. The baffle is vertically fixedly connected to the inner edge of the V-shaped plate, and the side of the baffle close to the drawer is located outside the groove. A push rod is vertically arranged on the inner side of the baffle. The push rod is vertically fixedly connected to the side of the drawer. The straight-line distance from the positioning block to the second hanging rod is greater than the maximum straight-line distance from the second hanging rod to the first hanging rod, and the length of the positioning block is greater than the length of the fixed shaft.

[0009] When the drawer is not put into the cabinet, all the openings of the V-shaped plates and the baffle plates on the inner walls of the cabinet on both sides of the freezing area are all facing forward, and the bottom of the V-shaped plate is in contact with the positioning block on the front side in the groove, and the movable rod is located at the end of the V-shaped slot. When the drawer is put into the cabinet, as the drawer is gradually pushed into the cabinet, the multiple push rods on both sides of the drawer gradually approach the baffle plates on the corresponding side and at the corresponding height, and the bottom of the drawer can be supported by the corresponding refrigerating coil or the inner wall of the bottom of the cabinet. As the drawer is continuously pushed, the multiple push rods on the drawer can be in contact with the baffle plates in the grooves at the corresponding height at the same time. As the drawer is continuously pushed, the push rods can push the baffle plates under the driving of the drawer, so that the V-shaped plate can be gradually deflected under the driving of the baffle plate with the fixed shaft as the center. In this process, as the V-shaped plate is deflected, the movable rod can roll along the V-shaped slot towards the direction close to the fixed shaft. As the movable rod moves, the distance between the first hanging rod and the second hanging rod gradually shortens, and at this time, the spring can gradually contract.

[0010] When the movable rod rolls to the position opposite to the fixed shaft in the V-shaped slot, as the V-shaped plate is further deflected, the movable rod can move along the V-shaped slot away from the fixed shaft. At this time, the spring is gradually stretched by the first hanging rod, and the reaction force of the spring on the V-shaped plate gradually increases. In this process, the side of the baffle plate originally facing downward can gradually face upward, and when the side passes the vertical center line of the fixed shaft, the side of the baffle plate facing upward can push the push rod to continue moving into the cabinet under the action of the force of the spring on the side facing downward, so that the drawer can be automatically retracted into the cabinet by a distance under the action of the pushing force of the baffle plate on the push rod. When the drawer is not completely pushed into the cabinet, the drawer can also be automatically completely retracted into the cabinet under the pushing of the reset device, so as to ensure that the cabinet door is not blocked by the drawer when the cabinet door is closed, and to ensure the freezing effect in the freezing area.

[0011] Further, a strip-shaped mounting groove is horizontally formed on each side of the drawer, and the mounting groove is below the bottommost push rod. A fixed strip is detachably mounted in the mounting groove. A support strip is horizontally and fixedly connected to the inner wall of the cabinet at the corresponding position of the fixed strip. Two positioning grooves are formed on the side of the support strip close to the drawer. The top of the positioning groove is in communication with the top of the support strip, and the front side groove wall of the positioning groove is inclined downward from top to bottom. The depth of the positioning groove on the front side, which is perpendicular to the side wall of the cabinet, is less than the depth of the positioning groove on the rear side, which is perpendicular to the side wall of the cabinet. A roller is arranged in each of the two positioning grooves, and the two rollers are vertically rotatably connected to the side of the drawer. The length of each of the two rollers corresponds to the depth of the corresponding positioning groove, which is perpendicular to the side wall of the cabinet. The front side of the support strip is designed as an inclined surface, and the thickness of the support strip is equal to the gap width between the side of the drawer and the side wall of the cabinet.

[0012] By being provided with the support strip, when the drawer is pushed into the cabinet, the rollers on both sides of the drawer can be located on the top of the support strip, and the front and rear inclined surfaces of the support strip can guide the drawer when the drawer is put into the cabinet, thereby helping the drawer to be more accurately put into the freezing area in the cabinet, and the support strip with a specific thickness can ensure that the drawer does not shake to both sides after being put into the cabinet;

[0013] In addition, when the drawer is pushed into the cabinet, the rollers can roll along the top of the support strip as the drawer moves, when the multiple push rods on both sides of the drawer contact the corresponding baffles, the baffles gradually start to deflect under the pushing of the push rods, and in this process, the two rollers can correspondingly approach the two positioning grooves, since the roller located at the rear side is longer than the roller located at the front side, the roller located at the rear side can roll along the top of the support strip until the roller located at the rear side enters the rear positioning groove, when the baffle completes deflection and contacts the positioning block located at the rear side, the two rollers also move to the inclined surface positions on the front sides of the two positioning grooves, at this time, the drawer can move a little distance along the inclined surface of the groove to the rear under the action of gravity, and the push rod can slide to the rear along the downward side of the baffle at this time, so that the drawer can be better received into the cabinet under the action of its own gravity in cooperation with the rollers, the positioning grooves and the reset device, thereby ensuring the airtightness when the cabinet door is closed.

[0014] Further, the multiple recesses are located on the same straight line, the heights of the multiple recesses gradually increase from front to rear, the horizontal distances between adjacent two recesses are the same, and the vertical height difference between adjacent two recesses is greater than the length of a single side of the V-shaped plate.

[0015] By setting the equidistant recesses, the reset devices in the recesses can also maintain the same distance, so that the push rods with corresponding heights can contact the reset devices with corresponding heights at the same time in the process of pushing the drawer into the cabinet, thereby enabling the multiple reset devices to simultaneously apply inward pushing force to the drawer, so that the drawer can be completely received into the drawer under the cooperation of the multiple reset devices.

[0016] Technical effects and advantages of the present application:

[0017] 1. By setting the reset device, when the push rods on both sides of the drawer contact the multiple baffles on the inner walls of the freezing area, the baffles can deflect under the pushing of the push rods as the drawer is continuously pushed, the baffles can automatically receive the drawer into the cabinet under the action of the spring after the baffles are deflected by a certain angle, thereby ensuring the airtightness when the cabinet door is closed, and ensuring the freezing effect of the refrigeration coil in the freezing area on the food in the drawer.

[0018] 2、when the drawer is not put into the cabinet, the two rollers on the sides of the drawer can roll along the top of the corresponding support bar, during which, when the baffle completes deflection and contacts with the locating block on the rear side, the two rollers also move to the inclined surface position in front of the two locating grooves, at this time, the drawer can move a little distance to the rear side along the inclined surface of the behavior groove under the action of gravity, and the push rod can slide to the rear side along the downward side of the baffle at this time, so that the drawer can be better put into the cabinet under the action of its own gravity in cooperation with the rollers, the locating grooves and the reset device.

A spring 510 is fixedly connected between the second hanging ring 509 and the first hanging ring 507, and the spring 510 is always in a stretched state. A baffle 511 matching the shape of the V-shaped plate 501 is provided on the side of the V-shaped plate 501 near the drawer 4. The baffle 511 is vertically fixedly connected to the inner edge of the V-shaped plate 501, and the side of the baffle 511 near the drawer 4 is located outside the groove. A lever 512 is vertically provided on the inner side of the baffle 511, and the lever 512 is vertically fixedly connected to the side of the drawer 4.

[0030] like Figure 6 and Figure 7 As shown, both sides of drawer 4 are horizontally provided with strip-shaped mounting grooves, and the mounting grooves are located below the bottom lever 512. A fixing strip 6 is detachably installed in the mounting groove. A support strip 7 is horizontally fixedly connected to the inner wall of the cabinet 1 at the corresponding position of the fixing strip 6. Two positioning grooves 8 are provided on the side of the support strip 7 near drawer 4. The top of the positioning groove 8 is connected to the top of the support strip 7, and the front wall of the positioning groove 8 is inclined from top to bottom and backward. The depth of the positioning groove 8 on the front side perpendicular to the side wall of the cabinet 1 is less than the depth of the positioning groove 8 on the rear side perpendicular to the side wall of the cabinet 1. Rollers 9 are provided in both positioning grooves 8. Both rollers 9 are vertically rotatably connected to the side of drawer 4, and the length of the two rollers 9 corresponds to the depth of the two positioning grooves 8 perpendicular to the side wall of the cabinet 1.

[0031] like Figure 2 As shown, multiple grooves are located on the same straight line, and the height of multiple grooves gradually increases from front to back. The horizontal distance between two adjacent grooves is the same, and the vertical height difference between two adjacent grooves is greater than the single side length of the V-shaped plate 501.

[0032] like Figure 2 As shown, several trays 10 are horizontally and detachably installed in the cold storage area, and the cold storage area is evenly divided by several trays 10.

[0033] like Figure 1 As shown, both the refrigerated and frozen sections are equipped with cabinet doors 11 on the front side, and the cabinet doors 11 are hinged to the front edge of the cabinet body 1.

[0034] like Figure 2 As shown, the front side of the support bar 7 is designed with a bevel, and the thickness of the support bar 7 is equal to the gap width between the side of the drawer 4 and the side wall of the cabinet 1.

[0035] like Figure 3 As shown, the straight-line distance from the positioning block 503 to the second hanging rod 508 is greater than the maximum straight-line distance from the second hanging rod 508 to the first hanging rod 506, and the length of the positioning block 503 is greater than the length of the fixed shaft 502.

[0036] Working principle: When drawer 4 is not placed inside cabinet 1, all the openings of the V-shaped plates 501 and baffles 511 on the inner walls of both sides of the freezer compartment cabinet 1 face forward, and the bottom of the V-shaped plate 501 is in contact with the positioning block 503 located on the front side in the groove. At the same time, the movable rod 504 is located at the end of the V-shaped groove. When drawer 4 is placed inside cabinet 1, as drawer 4 is gradually pushed into cabinet 1, the multiple levers 512 on both sides of drawer 4 gradually approach the baffle 511 on the corresponding side and at the corresponding height. The bottom of drawer 4 can be supported by the corresponding cooling coil 3 or the inner wall of the bottom of cabinet 1. As the drawer 4 continues to be pushed, the multiple levers 512 on the drawer 4 can simultaneously contact the baffles 511 in the corresponding height grooves. As the drawer 4 continues to be pushed, the levers 512 can push the baffles 511 under the action of the drawer 4, so that the V-shaped plate 501 can gradually deflect around the fixed shaft 502 under the action of the baffles 511. During this process, as the V-shaped plate 501 deflects, the movable rod 504 can roll along the V-shaped groove towards the fixed shaft 502. As the movable rod 504 moves, the distance between the first hanging rod 506 and the second hanging rod 508 gradually shortens, and at this time the spring 510 can gradually contract.

[0037] When the movable rod 504 rolls to the position opposite to the fixed shaft 502, the movable rod 504 can move along the V-shaped slot away from the fixed shaft 502 with the further deflection of the V-shaped plate 501, at this time the spring 510 is gradually stretched by the first hanging rod 506, and the reaction force of the spring 510 on the V-shaped plate 501 gradually increases, and in this process, the originally downward edge of the baffle 511 can gradually move upward, and when the edge passes the vertical center line of the fixed shaft 502, the upward edge of the baffle 511 can push the push rod 512 to continue to move into the cabinet body 1 under the action of the downward edge of the spring 510, so that the drawer 4 can be automatically retracted into the cabinet body 1 under the action of the push force of the baffle 511 on the push rod 512, and then when the drawer 4 is not completely pushed into the cabinet body 1, the drawer 4 can also be automatically completely retracted into the cabinet body 1 under the pushing of the reset device 5, so that when the cabinet door 11 is closed, the cabinet door 11 will not be blocked by the drawer 4, and the freezing effect in the freezing area is ensured.

[0038] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit it.
