Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a three-temperature zone two-door refrigerator. Background Art

[0002] With the popularization of refrigerators and the improvement of living standards, people's requirements for refrigerator performance are also increasing. The multi-temperature zone structure of refrigerators is one of the trends in the development of refrigerator performance. At present, for refrigerators with multiple temperature zones (mainly three temperature zones), the temperature compartments are separated by overall foaming during production and manufacturing. The mold manufacturing is complicated. Compared with ordinary two-temperature zone refrigerators, a series of molds must be newly opened: during manufacturing, the box body needs to be blister-formed, the box body is foamed, and a door body is added, requiring a total of three door bodies, one more door than the two-temperature zone. The existing dedicated variable temperature compartment with an independent door body is isolated from the cold storage compartment by a special foaming layer, resulting in a decrease in the volumetric efficiency of the box body and an increase in manufacturing costs. In addition, there is no moving device at the bottom of the existing refrigerator, and multiple people are required to operate when a larger refrigerator needs to be moved.

[0003] Therefore, we made improvements on this and proposed a three-temperature zone two-door refrigerator. Summary of the invention

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] Example 1 Please refer to Figure 1-7 A three-temperature zone two-door refrigerator comprises: a refrigerator body 1, wherein the upper and lower sides of the refrigerator body 1 are divided into a freezing chamber 2 and a refrigerating chamber 3, an insulation partition plate 4 is installed on the upper side of the interior of the refrigerating chamber 3, and the insulation partition plate 4 divides the upper layer of the refrigerating chamber 3 into a zero-degree chamber 5, and a temperature adjustment component 6 and a defrosting component 16 are arranged in the zero-degree chamber 5, and a moving component 7 and an adjusting component 8 are arranged at the bottom of the refrigerator body 1. A foaming isolation layer 15 integrally formed with the refrigerator body 1 is arranged between the freezing chamber 2 and the refrigerating chamber 3, a first door 9 corresponding to the freezing chamber 2 is hinged on one side of the refrigerator body 1, and a second door 10 corresponding to the refrigerating chamber 3 is hinged on one side of the refrigerator body 1. A first storage plate 11 is installed in the freezing chamber 2, a plurality of second storage plates 12 and storage boxes 13 are installed in the refrigerating chamber 3, and a plurality of storage frames 14 are installed on the side of the second door 10.

[0028] Implementation process: By installing an insulating partition plate 4 inside the refrigerating chamber 3, the insulating partition plate 4 divides the upper layer of the refrigerating chamber 3 into a zero-degree chamber 5. The two-door refrigerator can be divided into a freezer chamber 2, a refrigerating chamber 3 and a zero-degree chamber 5, thereby meeting the customer's needs for storing physical objects in multiple temperature zones. By setting the insulating partition plate 4 in the refrigerating chamber 3, the refrigerating chamber 3 and the zero-degree chamber 5 share a door body, reducing the need to set a special foaming layer isolation in the refrigerating chamber 3, resulting in a decrease in the volumetric efficiency of the box body and an increase in manufacturing costs.

[0029] Implementation benefits: The heat-insulating partition plate 4 provided in the cold storage room 3 enables the cold storage room 3 and the zero-degree room 5 to share a door body.

[0030] Example 2 The temperature control assembly 6 includes a thermostat 601 installed on the side wall of the zero-degree chamber 5, an adjusting knob 602 is installed on the outside of the thermostat 601, an air outlet 603 is opened on the side of the thermostat 601, an air outlet bin 606 is installed at the bottom air outlet of the thermostat 601 and passes through the insulation partition plate 4 and is located in the refrigeration chamber 3, a placement box 604 is installed on one side of the air outlet 603 in the zero-degree chamber 5, and a frame cover 605 is installed on the front side of the placement box 604. The defrost assembly 16 includes a defrost tray 1601 installed at the bottom of the placement box 604, a water receiving tray 1602 is installed inside the refrigerator body 1, a drain pipe 1603 located above the water receiving tray 1602 is installed inside the back plate of the refrigerator body 1, a drain adapter 1604 is installed at the upper end of the drain pipe 1603, a water receiving pipe 1605 that passes through the foaming layer of the refrigerator body 1 is installed on one side of the drain adapter 1604, and a water outlet 1606 located above the water receiving port of the water receiving pipe 1605 is opened on one side of the defrost tray 1601.

[0031] Implementation process: The temperature of the cold air discharged from the air outlet 603 and the air outlet bin 606 can be controlled by controlling the adjustment knob 602 on the thermostat 601. The air outlet 603 blows cold air into the zero-degree chamber 5, so that the zero-degree chamber 5 is close to the storage environment of 0°C but not lower than 0°C. The zero-degree chamber 5 helps to maintain the freshness and nutritional value of food by maintaining a stable low-temperature environment. The temperature of the cold air discharged from the air outlet 603 and the air outlet bin 606 is controlled separately, so that the zero-degree chamber 5 and the refrigerator chamber 3 are convenient for storing different foods. The defrost tray 1601 arranged at the bottom of the placement box 604 allows the frosted water on the wall of the zero-degree chamber 5 to be gathered together and flow into the water receiving pipe 1605 through the water outlet 1606 on the defrost tray 1601. The water receiving pipe 1605 transports the water to the drain pipe 1603 through the drain adapter 1604 and discharges it into the water receiving tray 1602 for collection.

[0032] Implementation benefits: It is convenient to guide and collect the frosted water in the wall of the zero-degree chamber 5.

When the refrigerator body 1 needs to be moved, the driving rod 703 is rotated to adjust the moving wheel 713 to face the ground. After the refrigerator body 1 is moved to the specified position, the driving rod 703 is rotated to adjust the supporting block 712 to face the ground. The threaded column 802 is driven to rotate in the threaded groove 801 by rotating the adjusting block 803. The distance between the cushion block 804 and the bottom of the refrigerator body 1 can be adjusted to ensure that the refrigerator body 1 can be stably placed on an uneven ground.
