Abstract
Description
Technical Field
[0001] The utility model relates to the field of commercial refrigerators, in particular to a refrigerator capable of realizing wind speed monitoring. Background Art
[0002] A freezer is a type of refrigeration equipment used to store food. Open commercial freezers are widely used in shopping malls and supermarkets. A fan is installed at the bottom of the freezer, blowing cold air into a longitudinally distributed air duct at the back of the freezer. The air is eventually blown out through the air duct at the top, forming an air curtain at the front opening of the freezer. This air curtain not only isolates the external hot air and ensures that the temperature inside the freezer remains low, but also does not block the customer's view, making it easier for them to view and select the food displayed in the freezer.
[0003] However, precisely because of the invisible nature of the air curtain, even if there is a problem with the facilities in the refrigerator, resulting in poor or no air flow, it cannot be known unless you are close to the refrigerator, which poses certain hidden dangers.
[0004] Therefore, a method or device that can solve the above problems is needed. Summary of the Invention
[0005] The utility model aims to solve the above-mentioned deficiencies in the prior art and provides a refrigerator with a simple structure, ingenious design, reasonable layout and the ability to effectively monitor whether the cooling system is working properly.

[0007] The top of the cabinet 1 is provided with a first bracket 8, on which an outer wind curtain wind speed sensor 9 and an inner wind curtain wind speed sensor 10 are provided. The outer wind curtain wind speed sensor 9 is located at the outer wind curtain outlet 6, and the inner wind curtain wind speed sensor 10 is located at the inner wind curtain outlet 7.
[0008] The back panel 2 is evenly provided with multiple rows of air outlet groups, each row of air outlet groups includes multiple air outlet holes 13 distributed at equal intervals. A second bracket 11 is provided on the back panel 2, and an in-cabinet wind speed sensor 12 is provided on the second bracket 11.
[0009] The outer air curtain wind speed sensor 9, the inner air curtain wind speed sensor 10 and the cabinet wind speed sensor 12 are all connected to the control system of the refrigerator.
[0010] The wind speed sensor 12 in the cabinet is located in the middle of the back plate in the height direction.
[0011] Compared with the prior art, the utility model has the following advantages:
[0012] This structural form of a freezer capable of wind speed monitoring features a simple structure, ingenious design, and rational layout. This unique design addresses the operational issues of conventional freezers. A wind speed sensor is provided at both the outer and inner air curtain outlets, respectively, to monitor the flow rates at the outlets in real time, thereby enabling monitoring of the operating status of both layers of air curtains. Furthermore, a wind speed sensor is provided at the air outlet 13 on the back panel to detect whether the cold air flowing from the back panel into the freezer is operating normally. This sensor enables real-time monitoring of the outlet terminals of the freezer's cold air system, thereby automatically determining whether any freezer problems exist. Furthermore, its simple manufacturing process and low manufacturing cost offer numerous advantages, making it particularly suitable for widespread application in this field and boasting a promising market prospect. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a front view of an embodiment of the present utility model.
[0014] Figure 2 It is a three-dimensional structural diagram of an embodiment of the present utility model. DETAILED DESCRIPTION
[0015] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figure 1 、 Figure 2 As shown: A refrigerator capable of realizing wind speed monitoring comprises a cabinet body 1, a back panel 2 is arranged inside the cabinet body 1, a back panel air duct 3 is formed between the back panel 2 and the rear shell of the cabinet body 1, the bottom of the back panel air duct 3 is connected to the chamber where the fan is located, and the top of the back panel air duct 3 is connected to the top air duct 4 arranged on the top of the cabinet body 1, and a partition plate 5 is provided at the outlet of the top air duct 4, which divides the outlet of the top air duct 4 into two parts: an outer air curtain outlet 6 and an inner air curtain outlet 7.
[0016] The top of the cabinet 1 is provided with a first bracket 8, on which an outer wind curtain wind speed sensor 9 and an inner wind curtain wind speed sensor 10 are provided. The outer wind curtain wind speed sensor 9 is located at the outer wind curtain outlet 6, and the inner wind curtain wind speed sensor 10 is located at the inner wind curtain outlet 7.
[0017] The back panel 2 is evenly provided with multiple rows of air outlet groups, each row of air outlet groups includes multiple air outlet holes 13 distributed at equal intervals. A second bracket 11 is provided on the back panel 2, and an in-cabinet wind speed sensor 12 is provided on the second bracket 11.
[0018] The outer air curtain wind speed sensor 9, the inner air curtain wind speed sensor 10 and the cabinet wind speed sensor 12 are all connected to the control system of the refrigerator.
[0019] The wind speed sensor 12 in the cabinet is located in the middle of the back plate in the height direction.
[0020] The working process of the refrigerator capable of realizing wind speed monitoring according to the embodiment of the present invention is as follows: Under normal working conditions, the fan in the refrigerator blows the air cooled by the evaporator into the back panel air duct 3. As the cold air moves from bottom to top in the back panel air duct 3, a portion of the cold air is directly blown into the interior of the cabinet body 1 through the air outlet holes 13 provided on the back panel 2. The wind speed sensor 12 in the middle of the cabinet can detect the wind speed of the cold air blown out of the corresponding air outlet hole 13.
[0021] Most of the cold air is blown upward along the back panel air duct 3 to the top air duct 4 and discharged through the outlet of the top air duct 4. Since the outlet direction of the top air duct 4 is downward, the cold air will form a cold air curtain from top to bottom in front of the opening of the refrigerator after being discharged from the outlet of the top air duct 4. Since a partition plate 5 is provided at the outlet, the partition plate will divide the above-mentioned air curtain into two parts: an outer air curtain on the outside and an inner air curtain on the inside. The blowing angles of these two parts of the air curtain are not parallel, thereby achieving a better effect of isolating the external hot air; during the operation of the refrigerator, the outer air curtain wind speed sensor 9 monitors the wind speed of the outer air curtain in real time, and the inner air curtain wind speed sensor 10 monitors the wind speed of the inner air curtain in real time.
[0022] All of the above-mentioned wind speed sensors are connected to the control system of the refrigerator and send the detected wind speed information to the control system in real time. If the control system finds that the wind speed value corresponding to a wind speed sensor is lower than the preset warning wind speed value, the control system will send instructions to the sound and light warning device to control it to issue a warning message, reminding the staff to check the working condition of the refrigerator in time and eliminate the fault.
