Description

Technical Field

[0001] The present invention relates to the fields of refrigerators and coffee machines, and in particular to a refrigerator structure with precise mechanical temperature control. Background Art

[0002] With the development of the refrigeration industry, refrigerators are becoming increasingly compact, placing higher demands on their design. The structure typically consists of a compressor cavity and a refrigerator compartment. The mechanical thermostat's main body and temperature sensor are often located within the compressor cavity. This heating of the compressor can affect the sensitivity of the temperature sensor, ultimately impacting the refrigerator's precise temperature control.

[0003] Furthermore, existing refrigerator temperature control devices are primarily divided into mechanical and electronic temperature control devices. Electronic temperature control devices are more expensive, while mechanical temperature control devices are less expensive. Because mechanical temperature control devices are significantly affected by ambient temperature fluctuations, conventional refrigerators using mechanical temperature control devices often add circuit modules to compensate for temperature deviations caused by ambient temperature fluctuations to achieve precise temperature control. This involves adding circuit modules to compensate for the winter and summer mode switches, increasing costs. Furthermore, during use, users struggle to notice and adjust the winter and summer mode switches, compromising convenience. Summary of the Invention

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 7 , embodiments of the present invention include:

[0026] Figures 1 to 4 The precise mechanical temperature-controlled refrigerator structure shown includes a mechanical thermostat and mutually isolated mechanical thermostat cavity A, compressor cavity B, and refrigerator freezer C. The mechanical thermostat 01 includes a mechanical thermostat body 01-1, a mechanical thermostat temperature-sensing tube 01-2, and a mechanical thermostat temperature-sensing tube front end 01-3. The mechanical thermostat body 01-1 is disposed within the mechanical thermostat cavity A. A process hole 04-1 is provided on the back cover 04. The operating end of the mechanical thermostat body 01-1 extends through the process hole 04-1 to the outside of the back for easy adjustment.

[0027] The front end 01-3 of the mechanical thermostat temperature sensing tube is arranged inside or on the inner wall of the refrigerator refrigerator C, and directly monitors the internal temperature of the refrigerator refrigerator C. The mechanical thermostat temperature sensing tube 01-2 is connected between the mechanical thermostat body 01-1 and the front end 01-3 of the mechanical thermostat temperature sensing tube and does not pass through the compressor cavity B, thereby reducing the adverse effects of the temperature changes inside the compressor cavity B on the mechanical thermostat temperature sensing tube 01-2.

[0028] The mechanical thermostat temperature sensing tube 01-2 is sleeved with a mechanical thermostat temperature sensing tube sleeve 01-4 located in the mechanical thermostat cavity A, which has a good thermal insulation effect, reduces the adverse effects of ambient temperature on the mechanical thermostat temperature sensing tube 01-2, and improves the temperature control accuracy of the mechanical thermostat.

[0029] like Figure 1As shown, the mechanical thermostat cavity A is a relatively closed cavity formed by the top cover 02, rear cover 04, main case 03, milk adapter 14 on the top of the case, fixing box 13, and front fixing plate 02-2 on the top cover. This reduces the impact of ambient temperature changes on the mechanical thermostat. Main case 03 is equipped with main case top insulation 03-1, located between the mechanical thermostat cavity A and the compressor cavity B. This insulation further reduces the transfer of heat from the compressor cavity B to the mechanical thermostat cavity A.

[0030] like Figure 2 As shown, the top cover 02, the rear cover 04 and the main box body 03 are fixed by the top cover rear fixing frame 02-1, and the structure is stable. The side of the top cover 02 is provided with a top cover side connector 18 connected to the milk adapter 14 on the top of the box body, which facilitates the coffee machine to extract milk.

[0031] The compressor cavity B is a relatively closed cavity surrounded by the main box 03, the back cover 04, the base 05 and the back of the refrigerator foaming box 10 in sequence. The compressor 08 and the condenser 06 are arranged in the compressor cavity B to refrigerate the refrigerator refrigerator C. The back cover 04 is provided with a switch 17. The switch 17 is linearly connected to the compressor 08 and the mechanical thermostat body 01-1, and the control is flexible.

[0032] The rear cover 04 is provided with a main cooling fan 09, and the condenser 06 is provided with a condenser fan 07 on one side. The main cooling fan 09 and the condenser fan 07 can be used alone or in combination. Figure 2 As shown, heat dissipation holes can also be processed on the back cover 04 to improve the heat dissipation and ventilation effect. The base 05 is provided with a vent hole connected to the compressor cavity B. Four support legs 15 are provided below the base 05 to maintain ground clearance and ensure the normal operation of the vent hole.

[0033] The main cooling fan 09 can be set to blow outward or inward, and the condenser fan 07 can be set to blow downward or upward. Figure 1 In the description of the case where the condenser fan 07 is horizontally arranged, the condenser 06 can be arranged to be vertical, and its corresponding condenser fan 07 is also arranged to be vertical. At this time, the condenser fan 07 can be arranged to blow air outward or inward.

[0034] Figures 1 to 4In the embodiment shown, when the refrigerator is operating normally, the compressor 08 will dissipate heat, and the condenser fan 07 will also dissipate heat. The main cooling fan 09 will extract the compressor cavity hot air AIR-3 formed in the compressor cavity B, and the condenser fan 07 will suck the heat dissipated by the condenser 06, that is, the condenser hot air AIR-2, downward. The normal temperature air AIR-1 entering from the bottom will enter the compressor cavity B through the air vents on the base 05, forming an air circulation loop that inlets normal temperature air and outlets hot air, thereby realizing the discharge of heat from the compressor cavity B.

[0035] Figures 5 to 7 In the embodiment shown, when the refrigerator is operating normally, the compressor 08 will dissipate heat, and the condenser fan 07 will also dissipate heat. The main cooling fan 09 will bring the external room-temperature air AIR-4 into the compressor cavity B, and the condenser fan 07 will blow the room-temperature air AIR-5 in the compressor cavity toward the condenser 06. The heat dissipated by the condenser 06 and the heat dissipated by the compressor will form hot air AIR-6 that is forced out of the compressor cavity, forming an air circulation loop that takes in room-temperature air and discharges hot air, thereby realizing the discharge of heat from the compressor cavity B.

[0036] like Figure 1 As shown, the refrigerator refrigerator C is a relatively closed cavity composed of a refrigerator door 11, a refrigerator foaming box 10, a box top fixing box 13 and a milk adapter 14. The box top fixing box 13 and the milk adapter 14 are located on the top of the refrigerator foaming box 10. A milk box assembly 12 is placed in the refrigerator refrigerator C. The milk box assembly 12 includes: a milk box 12-1, a milk box cover 12-2 and a milk tube 12-3. The milk box cover 12-2 is arranged on the top of the milk box 12-1 for sealing. The milk tube 12-3 is installed on the milk box cover 12-2 and extends into the milk box 12-1. The top of the milk tube 12-3 contains a socket corresponding to the milk adapter 14 for easy docking.

[0037] like Figure 3 As shown, the refrigerator door 11 is located at the front opening of the refrigerator foam box 10, which is convenient for opening to replace the milk box assembly 12. Figure 1 As shown, an LED light 16 can also be installed in the refrigerator foaming box 10. The controller of the LED light 16 is linked to the refrigerator door 11. The refrigerator door 11 is illuminated after it is opened. The LED light can also be set to be always on, which makes it easier to observe whether there is milk in the milk box 12-1.

[0038] like Figure 3 As shown, the front end 01-3 of the temperature sensing tube of the mechanical thermostat is located on the inner wall of the foam box 10 of the refrigerator, as shown in FIG. Figure 1 or Figure 5As shown, a mechanical thermostat temperature sensing tube front end fixing cover 10-3 is provided on the inner wall of the refrigerator foaming box 10, which is arranged on the outside of the mechanical thermostat temperature sensing tube front end 01-3 to protect the mechanical thermostat temperature sensing tube front end 01-3 without affecting the operation of the mechanical thermostat temperature sensing tube front end 01-3.

[0039] The top of the refrigerator foaming box 10 is provided with a longitudinal hole 10-1 for the foaming box thermostat temperature sensing tube extending downward, and the bottom of the longitudinal hole 10-1 of the foaming box thermostat temperature sensing tube is provided with a transverse hole 10-2 for the foaming box thermostat temperature sensing tube extending to the inner wall of the refrigerator foaming box 10. The mechanical thermostat temperature sensing tube 01-2 passes through the longitudinal hole 10-1 and the transverse hole 10-2 of the foaming box thermostat temperature sensing tube to reach the refrigerator foaming box 10. The longitudinal hole 10-1 and the transverse hole 10-2 of the foaming box thermostat temperature sensing tube are used to protect the mechanical thermostat temperature sensing tube 01-2, thereby improving the temperature control accuracy.

[0040] In summary, the present invention provides a refrigerator structure with precise mechanical temperature control, which adopts a low-cost mechanical thermostat, solves the problem of adverse effects of ambient temperature, ensures temperature control accuracy, and reduces production and maintenance costs.
