Description

Technical Field

[0001] The present invention belongs to the technical field of display cabinets, and in particular relates to a display cabinet with a self-adaptive adjustable air duct. Background Art

[0002] In the current display cabinet market, the required cabinet volume continues to increase, placing higher demands on refrigeration systems. Current products on the market generally use a fixed air duct structure with direct airflow. Due to the limitations of the cabinet structure, the direct airflow area cools quickly, effectively refrigerating beverages. However, the airflow through other areas is small, cooling slowly and maintaining poor refrigeration. This results in different sales volumes for beverages displayed in different locations. Furthermore, due to the uneven temperature inside the product, the cabinet continues to cool even after reaching the average temperature, increasing the product's energy consumption.

[0003] Patent No. CN202021868687.8 discloses a refrigerator comprising a cabinet body and a refrigeration assembly. The cabinet body is provided with two storage compartment groups spaced apart and arranged opposite to each other, with a refrigeration cavity formed between the two storage compartment groups. Each storage compartment group includes multiple storage compartments, which are stacked along the extension direction of the refrigeration cavity, and each storage compartment is provided with an air inlet connected to the refrigeration cavity. The refrigeration assembly includes a refrigeration module and an air guide module arranged in the refrigeration cavity. The refrigeration module is used for refrigeration, and the air guide module is used to introduce air in the refrigeration cavity into the multiple storage compartments. This device reduces the temperature difference between the storage compartments in the refrigerator and achieves a balanced cooling effect. Patent No. CN201510633964.4 discloses a refrigerator comprising a cabinet body and a refrigeration assembly, a refrigerator, and a refrigerator control method. In the embodiment provided by the present invention, two air outlets are provided at the top of the refrigerator access port, forming a first air curtain parallel to the plane of the access port and a second air curtain at an angle to the first air curtain. A second air duct is provided at the bottom of the access opening, opposite to the first air outlet, to form a third air curtain. This allows the first, second, and third air curtains to form a closed, three-dimensional buffer space. This fully utilizes the heat-insulating properties of the second and third air curtains, preventing external hot air from entering through the gaps and directly contacting the first air curtain, effectively isolating the hot air outside the refrigerator. This refrigerator control method uses a fan controller to control the fan power supply, the wind speed, and the wind pressure of the air curtain to enhance the heat-insulating effect of the air curtain according to temperature changes. When the internal temperature of the cabinet varies, it is necessary to add a variable air duct to the cabinet to balance the internal temperature. By adjusting the direction of the air duct inside the display cabinet, the cold air circulates evenly inside the product, and the temperature inside the cabinet remains consistent at all times. The thermostat detects the temperature more accurately, reducing energy consumption. Furthermore, through communication between the controller and the cloud platform, the internal temperature of the cabinet is detected, and the air duct operation status is promptly fed back. Therefore, a display cabinet with adaptively adjustable air ducts is proposed.

[0034] Unless expressly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising” will be understood to include the stated elements or components but not to exclude other elements or components.

[0035] Reference Figures 1-10 The display cabinet with adaptive air duct adjustment of the present invention includes a cabinet body 1, a bottom plate 10 is provided at the bottom of the cabinet body 1, two side panels 11 are provided at the left and right ends of the bottom plate 10, a first back panel 12 is provided between the rear sides of the two side panels 11, a second back panel 120 is provided side by side on the right side of the first back panel 12, and a top panel 13 is provided between the front side of the top of the second back panel 120 and the inner wall of the side panel 11 on its right side.

[0036] In the present invention, the top of the cabinet 1 is provided with an air conditioning component 2 and a monitoring box 3 in sequence from the left to the back. The bottom of the air conditioning component 2 is provided with a lower plate 21 which is arranged in an inclined manner. The lower plate 21 is installed between the punching plate 14 and the upper plate 20. The rear end of the lower plate 21 is fixed with an air duct plate 22. The air duct plate 22 has a Z-shaped structure. There are two through holes on the plate body of the air duct plate 22, and a duct fan 210 can be installed to transport cold air to the inside of the cabinet 1 through the duct fan 210. 22 rear horizontal end is provided with variable air duct 221 and several fixed air duct 220 from right to left, and variable air duct 221 and several fixed air duct 220 each occupy half of the rear horizontal end of air duct plate 22, and the top of variable air duct 221 is provided with several oblique frames 222 arranged side by side, and the oblique frames 222 are parallelogram frame structures, and several oblique frames 222 evenly separate the variable air duct 221, and each separated variable air duct 221 is connected to the rotating shaft. The adjustable fan blades 23 can be rotated to change the air outlet size of the variable air duct 221. Two thermostats 5 arranged side by side on the left and right are installed at the lower end of the rear side wall of the monitoring box 3. The two thermostats 5 are electrically connected to the inside of the monitoring box 3. The thermostat 5 near the right side is used to adjust the average temperature of the control box, and the thermostat 5 near the left side is used to adjust the temperature of the abnormal area. Two sensors 4 are provided on the inner wall of the first back plate 12 just behind the bottom of the air adjustment component 2, and a temperature sensing head 40 is provided at the outer end thereof. Among them, the sensor 4 near the right side of the first back plate 12 is facing the upper right side of the fixed air duct 220, and can monitor the average temperature of the box. The sensor 4 near the left side of the first back plate 12 is facing the upper left side of the variable air duct 221, and monitors the temperature of the abnormal area of ​​the box. The two thermostats 5 and the two sensors 4 are respectively connected through installation lines 50, and the different temperature conditions detected are transmitted to the monitoring box 3 through signals.

[0037] First, a wire rod 130 is inserted and fixed on the top of the top plate 13, and a punching plate 14 is provided under the air regulating component 2. When the installation wire 50 is connected, it enters the cabinet 1 through the wire rod 130 and is connected to the two sensors 4 respectively. The punching plate 14 is provided to support the air regulating component 2.

[0038] Secondly, the bottom end of the lower plate 21 is fixed to the top rear end of the perforated plate 14, and two duct fans 210 arranged side by side are installed on the lower plate 21. The duct fans 210 are facing the front through holes of the perforated plate 14, so that cold air circulates inside the cabinet 1.

[0039] Specifically, the front side walls of the plurality of oblique frames 222 are respectively fixed on the vertical end plates of the air duct plate 22 , and a strap 230 is fixed on the front side wall of each adjustable fan blade 23 . A longitudinally arranged convex column 2301 is provided on the top of the strap 230 .

[0040] Furthermore, a stepper motor 231 is fixed on the vertical end plate of the duct plate 22 located in the middle position of the variable air duct 221, and the output shaft of the stepper motor 231 is rotatably connected to the bridge plate 230 of the adjustable fan blade 23 on the opposite side. When the temperature of the abnormal area displayed by the thermostat 5 is higher than the average temperature in the box displayed by the thermostat 5 on the left, the stepper motor 231 is started to rotate, driving several adjustable fan blades 23 to rotate, forming an angle of 45° with the variable air duct 221, so that the direction of the cold air on the left is blown along the inclined angle, thereby increasing the cooling capacity in the abnormal area and accelerating the cooling speed. If the angle of the variable air duct 221 is maintained at 45° for a certain period of time, the temperature of the abnormal area is consistent with the average temperature of the cabinet 1, the angle of the variable air duct 221 is adjusted to 90°, and the direction of the cold air on the right is changed to straight downward.

[0041] When the air duct angle remains at 45° for a certain period of time, and the temperature in the abnormal area is still higher than the average temperature of the cabinet 1, the controller 32 uploads an abnormal signal to the cloud platform 30, and the signal transmitter 31 reflects the data abnormality to the product operator, who notifies the customer and performs after-sales maintenance and inspection.

[0042] In the above scheme, the temperature of the abnormal area displayed by the thermostat 5 on the left is consistent with the average temperature in the cabinet 1 displayed by the thermostat 5 on the right. The air duct angle remains unchanged at 90°, and the direction of the cold air on the right is changed to straight downward. The cooling capacity of the abnormal area remains unchanged and the temperature remains stable.

[0043] It is worth noting that a horizontally arranged connecting rod 232 is provided at the front end of several adjustable fan blades 23, and a clamping block 2320 is provided on the top of the connecting rod 232 that matches the position of several bosses 2301. The front end of the boss 2301 is clamped and fixed to the top of the clamping block 2320. Through the arranged connecting rod 232, several adjustable fan blades 23 are driven to rotate at the same time, and form different angles with the variable air duct 221 to perform straight blowing or inclined blowing.

[0044] In addition, a cloud platform 30 is provided at the front end of the monitoring box 3, an indicator light 301 is provided at the lower end of the cloud platform 30, a controller 32 is provided on the cloud platform 30, and a signal transmitting rod 31 is provided on the top of the cloud platform 30. The controller 32 is respectively connected to the thermostat 5, the indicator light 301 and the signal transmitting rod 31 through wiring diagrams not marked. The abnormal temperature signal received by the controller 32 is reflected to the product operator through the signal transmitting rod 31. When an abnormal temperature signal occurs, the product operator gives feedback to the customer and lights up the indicator light 301 to remind.

[0045] The working principle of the display cabinet with adaptive air duct adjustment of the present invention is specifically as follows: at the beginning, the temperature is sensed by the sensor 4, and the thermostat 5 measures the temperature. When the temperature does not reach the set value, the thermostat 5 is started to adjust the stepping motor 231 to rotate, so that the adjustable fan blade 23 rotates, and the angle of the variable air duct 221 is adjusted by 45 degrees. It is judged that the thermostat 5 has reached the measured temperature value, so that the adjustable fan blade 23 rotates, and the angle of the variable air duct 221 is adjusted by 90 degrees. The thermostat 5 is turned off and the measured temperature value has not been reached. After a delay judgment, it is uploaded to the cloud platform 30 through the controller 32.
