Description

Technical Field

[0001] This utility model relates to the field of thermostatic control cabinet technology, and in particular to an intelligent thermostatic control cabinet with high efficiency and anti-airflow interference. Background Technology

[0002] Currently, the main challenge facing single-liner dual-temperature combination cabinets (such as single-liner dual-temperature beverage and wine combination cabinets) is the problem of temperature crosstalk. Because the inner liner has a single structure, despite different temperature zone controls in the design, temperature differences can still cause interference within the cabinet, affecting the accuracy and stability of temperature control. To solve this problem, some high-end combination cabinets use a dual-evaporator system, providing independent cooling for different temperature zones through independent evaporators and condensers. However, because dual evaporators require more components and a more complex control system, this design, while effective, also leads to higher energy consumption and costs. Another solution is to use a single evaporator and a counter-blowing fan design, using an air duct plate to direct cold air from the low-temperature zone (e.g., the beverage zone) to the medium-temperature zone (e.g., the wine zone), thereby improving the temperature independence between the zones. While this design can reduce energy consumption and save costs, problems such as cold air leakage through the counter-blowing holes in the air duct plate can still occur, leading to uneven temperature and affecting temperature control stability. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an intelligent constant temperature control cabinet with high efficiency and anti-airflow crosstalk.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A highly efficient intelligent thermostatic control cabinet with anti-airflow interference includes a cabinet body and a first storage area and a second storage area arranged vertically. The first storage area and the second storage area are separated by an intermediate air duct plate. A first airflow channel is opened on the cabinet body at a position corresponding to the first storage area. The first airflow channel is connected to the first storage area through an air outlet and a return air outlet. An air outlet louver is provided in the air outlet, and a return air louver is provided in the return air outlet. A second airflow channel is opened on the cabinet body at a position corresponding to the second storage area. The second airflow channel is connected to the second storage area. A blower and a refrigeration evaporator are arranged vertically in the second airflow channel. An intermediate airflow channel is opened on the intermediate air duct plate, which is connected to both the first airflow channel and the second airflow channel. A centrifugal fan is fixed in the intermediate airflow channel.

[0006] Preferably, a foam layer is provided on the side of the intermediate airflow channel near the first storage area.

[0007] Preferably, the intermediate air duct plate is provided with an elastic sealing strip on the side near the cabinet door, so that the elastic sealing strip fits tightly against the cabinet door when the cabinet door is closed.

[0008] Preferably, a deodorizer is fixed to the top of the first storage area, and a first temperature sensor is installed inside the deodorizer.

[0009] Preferably, a second temperature sensor is provided in the second storage area.

[0010] Preferably, the first storage area is provided with drawer shelves, and drawer guides are provided on both sides of the drawer shelves. Slide grooves are symmetrically opened on both sides of the first storage area, and each drawer guide is in sliding contact with one of the slide grooves.

[0011] Preferably, the second storage area is provided with at least one layer of glass shelves, and the second storage area is provided with at least one set of guide grooves in the vertical direction to support and guide the glass shelves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention places the evaporator within the second airflow channel, using a blower to directly blow cold air into the second storage zone. The cold air is then precisely guided to the first storage zone via a centrifugal fan, a central airflow channel, and a first airflow channel. Once the first temperature sensor detects that the temperature in the first storage zone has reached a set value, the control system shuts off the centrifugal fan. The outlet and return air louvers close due to gravity, preventing heat exchange between the different temperature zones of the first and second storage zones, ensuring precise temperature stability, minimizing cold air waste, improving cold air distribution efficiency, and optimizing energy use. This invention is suitable for thermostatic cabinets with two different refrigeration temperature zones, specifically addressing the temperature crosstalk problem in wine storage and beverage refrigeration. Through a unique structural design and intelligent control technology, it automatically adjusts the start and stop of the centrifugal fan based on real-time temperature changes in the first storage zone, ensuring that the temperature in the first storage zone remains within the set range. This significantly improves the system's temperature control accuracy, energy efficiency, and stability, while maintaining low cost and ensuring the independence and precise temperature control of the two temperature zones.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] This utility model is applicable to a constant temperature control cabinet with two different refrigeration temperature zones. The following description uses the beverage refrigeration zone and the red wine refrigeration zone as examples.

[0024] Example 1: As Figure 1As shown, a highly efficient intelligent thermostatic control cabinet with anti-airflow interference includes a cabinet body 1 and a first storage area 2 and a second storage area 3 arranged vertically. A deodorizer 21 is fixed to the top of the first storage area 2, and a first temperature sensor is installed inside the deodorizer 21. A second temperature sensor is installed inside the second storage area 3. The first storage area 2 and the second storage area 3 are separated by an intermediate air duct plate 4. A first airflow channel 11 is opened on the cabinet body 1 at a position corresponding to the first storage area 2. The first airflow channel 11 is connected to the first storage area 2 through an air outlet and a return air outlet. An air outlet louver 13 is installed in the air outlet, and a return air louver 14 is installed in the return air outlet. A second airflow channel 12 is opened on the cabinet body 1 at a position corresponding to the second storage area 3. The second airflow channel 12 is connected to the second storage area 3. A blower 15 and a refrigeration evaporator 16 are arranged vertically in the second airflow channel 12. Figure 2 As shown, the intermediate air duct plate 4 has an intermediate airflow channel 41 that communicates with the first airflow channel 11 and the second airflow channel 12 respectively. A centrifugal fan 42 is fixed inside the intermediate airflow channel 41, and a foam layer is provided on the side of the intermediate airflow channel 41 near the first storage area 2. The blower 15, the refrigeration evaporator 16 and the centrifugal fan 42 are controlled by a controller and a control system.

[0025] In use, red wine is placed in the first storage area 2, and beverages are placed in the second storage area 3. The temperature of the first storage area 2 is monitored by a first temperature sensor, and the temperature of the second storage area 3 is monitored by a second temperature sensor. Since the deodorizer 21 is generally placed close to the red wine, placing the first temperature sensor inside the deodorizer 21 allows for more accurate temperature data.

[0026] Initially, the temperatures in the first storage area 2 and the second storage area 3 have not reached the preset temperature values. The controller activates the blower 15, the evaporator 16, and the centrifugal fan 42. At this time, the direction of the cold air flow inside the thermostatic control cabinet is as follows: Figure 4 As shown, the blower 15 drives the cold air to circulate within the second storage zone 3. Simultaneously, the centrifugal fan 42 drives a portion of the cold air through the intermediate airflow channel 41 and the first airflow channel 11, before it enters the first storage zone 2 through the outlet louver 13. The air in the first storage zone 2 flows out through the return air louver 14, completing the airflow circulation within the first storage zone 2. When the first temperature sensor detects that the temperature in the first storage zone 2 has reached the first preset value, the centrifugal fan 42 is turned off, and the outlet louver 13 and return air louver 14 close under their own gravity. When the temperature in the second storage zone 3 has not yet reached the second preset value, the direction of the cold air flow in the thermostatic control cabinet is as follows: Figure 5As shown, the cold air circulates only within the second storage zone 3 until the temperature in the second storage zone 3 reaches the second preset value. At this point, the controller shuts off the blower 15 and the evaporator 16. When the first temperature sensor detects that the temperature in the first storage zone 2 has risen to the third preset value, the centrifugal fan 42 is turned on. When the second temperature sensor detects that the temperature in the second storage zone 3 has risen to the fourth preset value, the blower 15 and the evaporator 16 are turned on. In this way, the temperature control of the thermostatic cabinet is completed.

[0027] This invention places the evaporator 16 within the second airflow channel 12, and uses a blower 15 to directly blow cold air into the second storage zone 3. The cold air is then precisely guided to the first storage zone 2 via a centrifugal fan 42, an intermediate airflow channel 41, and a first airflow channel 11. Once the first temperature sensor detects that the temperature in the first storage zone 2 has reached a first set value, the control system shuts off the centrifugal fan 42. The outlet louvers 13 and return louvers 14 close due to gravity, preventing heat exchange between the different temperature zones of the first and second storage zones 3, ensuring precise temperature stability, minimizing cold air waste, improving cold air distribution efficiency, and optimizing energy use. This air conditioning control system can automatically adjust the start and stop of the centrifugal fan 42 based on real-time temperature changes in the first storage zone 2, ensuring that the temperature in the first storage zone 2 remains within the set range.

[0028] like Figure 1 As shown, an elastic sealing strip 43 is provided on the side of the intermediate air duct plate 4 near the cabinet door of the cabinet body 1. When the cabinet door is closed, the elastic sealing strip 43 fits tightly against the cabinet door. By providing the elastic sealing strip 43, cold air can be prevented from flowing in the gap between the intermediate air duct plate 4 and the cabinet door, further preventing heat exchange between the first storage area 2 and the second storage area 3.

[0029] like Figure 3 As shown, the first storage area 2 is equipped with a drawer shelf 22, and drawer guide rails 23 are respectively provided on both sides of the drawer shelf 22. The first storage area 2 has symmetrical sliding grooves on both sides, and each drawer guide rail 23 slides in contact with one of the sliding grooves. Red wine can be placed horizontally in the drawer shelf 22. Since there are hollow gaps at the bottom of the drawer shelf 22, the red wine can be limited. By setting the drawer guide rails 23 and sliding grooves, it is convenient to put and take out the red wine.

[0030] like Figure 1 As shown, the second storage area 3 is provided with at least one layer of glass shelf 31. The second storage area 3 is provided with at least one set of guide grooves in the vertical direction. The guide grooves support and guide the glass shelf 31, and beverages can be placed vertically on the glass shelf 31 for support.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
