Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a refrigerator temperature control structure for regulating the return air of the refrigerator. Background Technology

[0002] Current refrigerator temperature control technology typically achieves temperature control by adjusting the size of the air inlet in the freezer compartment, for example, using a freezer knob / spindle mechanism. However, in the low-temperature environment of the freezer compartment, the knob / spindle is prone to increased adjustment resistance due to condensation and ice formation, or even complete jamming, affecting user experience and temperature control accuracy.

[0003] To address these issues, those skilled in the art have proposed a refrigerator temperature control structure for regulating the return air temperature of the refrigerator. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a refrigerator temperature control structure for adjusting the refrigeration return air, which aims to solve the problem that "existing refrigerator temperature control technology usually achieves temperature control by adjusting the size of the freezer compartment air inlet, for example, by using a freezer knob switch structure. However, in the low-temperature environment of the freezer compartment, the knob switch is prone to increased adjustment resistance due to condensation and ice formation, or even complete jamming, affecting user experience and temperature control accuracy."

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A refrigerator temperature control structure for regulating the return air of the refrigerator includes:

[0008] A freezer evaporator and a refrigerator liner, wherein the refrigerator liner is located at the lower end of the freezer evaporator;

[0009] A refrigerator compartment is installed on the inner wall of a refrigerator box. The refrigerator compartment is connected to the freezer evaporator through an air duct. The refrigerator compartment has a refrigerator air outlet and a refrigerator air inlet. The refrigerator air outlet and the refrigerator air inlet together form a refrigerator air duct. A baffle is installed in the refrigerator air inlet. An adjustment component is installed on the refrigerator compartment. The adjustment mechanism is configured to be driven by external operation. The baffle moves linearly within the refrigerator air inlet.

[0010] As a preferred embodiment of the refrigerator refrigeration return air temperature control structure of this utility model, wherein: an installation frame is fixedly installed in the refrigeration air inlet, and the baffle is installed in the installation frame.

[0011] As a preferred embodiment of the refrigerator refrigeration return air temperature control structure of this utility model, the adjustment component includes two connecting pieces and two connecting strips symmetrically fixed to the inner wall of the mounting frame. The corresponding connecting pieces and connecting strips form a slide with the inner wall of the mounting frame, and the baffle is disposed in the slide.

[0012] As a preferred embodiment of the refrigerator refrigeration return air temperature control structure of this utility model, the adjustment component further includes a lever, which is fixedly connected to the baffle and is used to receive external operating force to drive the baffle to move.

[0013] As a preferred embodiment of the refrigerator temperature control structure for adjusting the return air of the refrigerator compartment according to this utility model, wherein: the freezer evaporator and the refrigerator compartment are jointly equipped with an air inlet connector and an air outlet connector, and the air duct is connected through the air inlet connector and the air outlet connector.

[0014] As a preferred embodiment of the refrigerator temperature control structure for adjusting the refrigeration return air according to this utility model, a drain pipe is installed on the refrigerator compartment for draining condensate.

[0015] The beneficial effects of this utility model's refrigerator refrigeration return air temperature control structure are as follows: External operating force is received via a lever, driving the baffle to move linearly within the mounting frame, ensuring smooth and unbiased movement. The baffle moves linearly within the refrigeration air inlet, adjusting the return air flow by changing the ventilation cross-sectional area of ​​the air inlet. A smaller ventilation area increases return air resistance, reducing the rate at which cold air enters the refrigerator compartment and raising its temperature; conversely, a larger ventilation area accelerates cold air circulation and lowers the temperature.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides a refrigerator refrigeration return air temperature control structure, including: a freezer evaporator 100 and a refrigerator liner 200, with the refrigerator liner 200 located at the lower end of the freezer evaporator 100;

[0027] The refrigerator compartment 300 is installed on the refrigerator liner 200. The refrigerator compartment 300 is connected to the freezer evaporator 100 through an air duct. The refrigerator compartment 300 is provided with a refrigerator air outlet 301 and a refrigerator air inlet 302. The refrigerator air outlet 301 and the refrigerator air inlet 302 together form a refrigerator air duct. A baffle 303 is provided in the refrigerator air inlet 302. An adjustment component 304 is provided on the refrigerator compartment 300. The adjustment mechanism 304 is configured to be driven by external operation. The baffle 303 moves linearly within the refrigerator air inlet 302.

[0028] The refrigerated air inlet 302 is fixedly installed with an installation frame 308, and the baffle 303 is installed in the installation frame 308.

[0029] The adjustment component 304 includes two connecting pieces 304a and two connecting strips 304b symmetrically fixed to the inner wall of the mounting frame 304a. The corresponding connecting pieces 304a and connecting strips 304b form a slide with the inner wall of the mounting frame 308, and the baffle 303 is disposed in the slide.

[0030] Furthermore, the adjustment component 304 also includes a lever 304c, which is fixedly connected to the baffle 303 and is used to receive external operating force to drive the baffle 303 to move.

[0031] During use, the evaporator 100 acts as the core of the refrigeration system, continuously generating low-temperature cold air. The cold air enters the refrigerator compartment 300 and is evenly distributed in the refrigerator area through the refrigerator air outlet 301. The cold air returns to the evaporator 100 through the refrigerator air inlet 302, forming a closed-loop air circulation.

[0032] The external operating force is received by the lever 304c, which drives the baffle 303 to move linearly in the mounting frame 308, so that the baffle moves smoothly and without deviation. The baffle 303 is linearly displaced in the refrigeration air inlet 302. By changing the ventilation cross-sectional area of ​​the air inlet, the return air flow is adjusted. If the ventilation area is reduced, the return air resistance increases, the rate at which cold air enters the refrigeration compartment decreases, and the temperature of the refrigeration compartment rises. Conversely, if the ventilation area is increased, the cold air circulation is accelerated and the temperature is lowered.

[0033] Example 2

[0034] Reference Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, the freezer evaporator 100 and the refrigerator compartment 300 are both equipped with an air inlet connector 305 and an air outlet connector 306. The air duct is connected through the air inlet connector 305 and the air outlet connector 306, and a closed-loop air duct circulation is achieved through the air inlet connector 305 and the air outlet connector 306.

[0035] Specifically, a drain pipe 307 is installed on the refrigerator compartment 300 to drain condensate and prevent water from freezing at low temperatures.

[0036] Cold air enters the refrigerator compartment 300 through the air inlet connector 305 and is evenly distributed in the refrigerator area through the refrigerator air outlet 301; the cold air returns to the freezer evaporator 100 through the refrigerator air inlet 302 and the air outlet connector 306, forming a closed-loop air circulation.

[0037] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
