Description

Refrigerator variable temperature box manual damper adjustment mechanism

technical field

The utility model relates to a damper adjustment mechanism, in particular to a manual damper adjustment mechanism of a variable temperature box of a refrigerator, and belongs to the technical field of household appliances.

Background technique

Refrigerators can be divided into direct cooling and air cooling. Air-cooling refrigerators are designed with a cooling room inside the refrigerator. The cooling room is generally between the food storage area of the refrigerator and the back of the cabinet. The cooling room is equipped with main refrigeration components. One of the evaporators and the forced convection fan communicate with the cooling chamber and the food storage area with an air duct. The forced convection fan in the cooling room is near the evaporator. Under the action of the fan, the airflow is forced to flow through the surface of the evaporator and blow cold air to the storage area. The cold air takes away the heat from the storage area and returns to the cooling room. This cycle repeats. Under the control of the refrigerator controller, a certain low temperature is maintained in the refrigerator.

With the improvement of people's living standards and the development of refrigerator technology, most of the air-cooled refrigerators sold on the market have a multi-greenhouse (zone) structure. The basic compartments include refrigerators and freezers. The fruit and vegetable area for fruits and vegetables, the ice temperature area with a temperature around 0°C (suitable for chilled fish), the ice room, etc., each temperature area has different temperature and humidity to adapt to the preservation and storage of different types of food. The temperature adjustment of each room and each temperature zone of the air-cooled refrigerator is realized by the amount of cold air supply.

However, the amount of cold air supply often needs to be adjusted by an attached electric adjustment device, and the user of the refrigerator cannot realize accurate manual adjustment anytime and anywhere.

Description of drawings

Fig. 1 is a structural schematic diagram of the utility model.

The meaning of each reference mark in the figure is as follows:

1 Damper cover 2 Control rod

3 Transmission gear 4 Damper connecting rod

5 Guide serrations 6 Lower cover

7 handles

Detailed ways

The manual damper adjustment mechanism of the refrigerator temperature change box shown in Figure 1 is related to the temperature change box, and the air duct is connected behind the temperature change box. Cover plate 1, one end of the control transmission device is connected to the damper cover plate 1, and the damper cover plate 1 is located at the air duct opening. Further, the control transmission device includes a control rod 2, a transmission gear 3, and a damper connecting rod 4. The control rod 2 is provided with guide serrations 5 laterally, and the end of the damper connecting rod 4 is longitudinally provided with guide serrations 5. The control rod 2 The damper connecting rod 4 is connected through the transmission gear 3, and the gears are matched. At the same time, in order to allow the utility model to better match the structure of the existing refrigerator, a lower cover 6 is provided on the top of the variable temperature box, and the manual damper adjustment mechanism is distributed in the lower cover 6. cover plate.

Referring again to FIG. 1 , the first end of the damper connecting rod 4 is provided with a damper cover plate 1 , and the damper cover plate 1 is rotationally connected with the lower cover plate 6 through a pivot pin. That is to say, the top of the damper cover plate 1 can freely rotate around the bottom edge in a circumferential direction. At the same time, the connection between the damper cover plate 1 and the air duct is provided with a leak-proof sponge pad. This can ensure that the cold air does not leak during transmission. Considering the comfort of the user, a handle 7 is provided at one end of the control rod 2 . In this way, the user can control and guide the control lever 2 through the handle 7 .

When the user pushes the control rod 2 laterally to the left end through the handle 7, the guide serrations 5 distributed laterally on the control rod 2 drive the transmission gear 3 to rotate. Subsequently, the transmission gear 3 rotates to drive the guide serrations 5 distributed longitudinally at the end of the damper link 4 . Specifically, make the damper connecting rod 4 present a push-up action. At the same time, the damper connecting rod 4 drives the damper cover plate 1 to rotate the damper cover plate 1 through the pivot pin, and the damper cover plate 1 gradually closes around the pivot pin in a circumferential manner to narrow the damper opening. Finally, the amount of cold air entering the cooling room through the air duct is reduced.

Looking further, if the user pushes the control lever 2 laterally to the right end through the handle 7, the transmission gear 3 is driven to rotate through the guide serrations 5 distributed laterally on the control lever 2. Then, the transmission gear 3 rotates to drive the guide sawtooth 5 distributed longitudinally at the end of the damper connecting rod 4 . That is to say, let the damper connecting rod 4 present a pull-down trend. Specifically, the damper connecting rod 4 at this time drives the damper cover 1 to rotate the damper cover 1 through the pivot pin, and the damper cover 1 gradually opens around the pivot pin in a circular manner to enlarge the damper opening. As a result, the flow of cold air entering the temperature-changing room through the air duct is increased.

It can be seen from the above text description and in conjunction with the accompanying drawings that after the utility model is adopted, the user can manually adjust the air door at any time according to the actual use status of the refrigerator. Moreover, the cooperation between the guide sawtooth 5 and the drive transmission gear 3 is adopted to make the adjustment scale of the damper more accurate. Simultaneously, the utility model is very easy to be combined with the existing air-cooled refrigerator, and is convenient to popularize in the technical field.

Of course, the above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. In addition to the above-mentioned embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
