Description

Technical Field

[0001] This utility model relates to the field of refrigerator temperature control technology, and more specifically to a temperature control structure for an energy-saving refrigerated display cabinet. Background Technology

[0002] Refrigerated display cases used in supermarkets, beverage shops, hotels, restaurants, and other commercial channels typically require frequent opening and closing of doors to retrieve goods and the loading and unloading of large quantities of merchandise. Currently, because the heat capacity of goods in display cases is generally high, and common electronic thermostats usually do not detect the actual temperature of the goods, the temperature of the goods can easily become too cold or too hot during frequent door openings and closings. In refrigerated display cases, the fan airflow structure is often a fixed guide plate, and the temperature sensor is often a single-position sensor. This makes it impossible to synchronously adjust the angle of the airflow structure based on the switch signal and the uniformity of the temperature inside the cabinet, easily leading to uneven temperature distribution and additional energy consumption.

[0003] Existing patented and commercially available refrigerated display cases lack a temperature control structure that simultaneously integrates multiple sensors and air deflectors. With frequent door opening and closing, the temperature of merchandise in existing display cases is prone to rapid increases, while the temperature drops excessively during and after the door opening and closing process, resulting in prolonged operation of the refrigeration system. Utility Model Content

[0004] In response to the shortcomings of existing technologies, the inventors have developed an energy-saving temperature control structure for refrigerated display cabinets through long-term practical research. Based on multi-position sensors and an adjustable-angle baffle structure, the temperature inside the cabinet is controlled within a more uniform and stable temperature range when the door is frequently opened and closed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A temperature control structure for an energy-saving refrigerated display case includes an evaporator fan, an evaporator, a baffle assembly, a sensor assembly, and a temperature controller. The evaporator fan and the evaporator are arranged adjacent to each other, and the baffle assembly is located on the side of the evaporator away from the evaporator fan. The baffle assembly includes an upper baffle, a baffle control assembly, and a lower baffle. The baffle control assembly includes a baffle controller, an upper rotating arm, and a lower rotating arm. The sensor assembly includes a first temperature sensor, a second temperature sensor, a third temperature sensor, and a door magnet.

[0007] Furthermore, the evaporator fan is installed inside the evaporator fan cover.

[0008] Furthermore, the lower guide plate is disposed at the bottom of the upper guide plate, and the upper guide plate and the lower guide plate are rotatably connected together, wherein the lower guide plate can rotate along the length direction of the upper guide plate.

[0009] Furthermore, the lower guide plate is provided with several ventilation holes.

[0010] Furthermore, the deflector controller is provided with a rotating shaft, one end of the upper rotating arm is fixed to the rotating shaft, the other end of the upper rotating arm is rotatably connected to the lower rotating arm, and the other end of the lower rotating arm is fixed to the lower deflector.

[0011] Furthermore, the first temperature sensor is positioned close to the bottom of the freezer's glass door.

[0012] Furthermore, the second temperature sensor is located at the air outlet of the deflector assembly.

[0013] Furthermore, the third temperature sensor is located next to the evaporator.

[0014] Furthermore, the door magnet is installed on the freezer door.

[0015] The beneficial effects of this utility model are:

[0016] By installing temperature sensors at different locations within the freezer, the real-time temperature of the freezer can be sensed from all angles. By adjusting the tilt angle of the lower deflector assembly, the airflow organization within the freezer can be more flexibly adjusted, resulting in more stable and uniform temperature control of the goods inside the freezer, thus expanding its application range.

Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the scope of this utility model.

[0022] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0023] See Figure 1 and Figure 2 The present invention relates to a temperature control structure for an energy-saving refrigerated display cabinet, comprising an evaporator fan 1, an evaporator 2, a baffle plate assembly, a sensor assembly, and a temperature controller.

[0024] Evaporator fan 1 and evaporator 2 are arranged adjacent to each other on one side of the freezer, with evaporator fan 1 housed inside an evaporator fan cover. The thermostat is electrically connected to the freezer compressor and contains a temperature control module. The thermostat can control evaporator fan 1, and evaporator fan 1 and evaporator 2 achieve air circulation within the freezer, thereby adjusting the freezer's cooling effect.

[0025] On the side of the evaporator 2 away from the evaporator fan 1, there is a guide vane assembly, which includes an upper guide vane 3, a guide vane control assembly 4, and a lower guide vane 5. The lower guide vane 5 is located at the bottom of the upper guide vane 3, and the upper guide vane 3 and the lower guide vane 5 are rotatably connected together. The lower guide vane 5 can rotate along the length of the upper guide vane 3. Several ventilation holes are provided on the lower guide vane 5.

[0026] The deflector control assembly 4 includes a deflector controller 41, an upper rotating arm 42, and a lower rotating arm 43. The deflector controller 41 is provided with a rotating shaft 44. One end of the upper rotating arm 42 is fixed to the rotating shaft 44, and the other end of the upper rotating arm 42 is rotatably connected to the lower rotating arm 43. The other end of the lower rotating arm 43 is fixed to the lower deflector 5.

[0027] The deflector controller 41 is equipped with a deflector control module, which can control the rotation of the rotating shaft 44, thereby driving the upper rotating arm 42 to rotate axially along the rotating shaft 44. The rotation of the upper rotating arm 42 can lift the lower rotating arm 43, and the lifting of the lower rotating arm 43 can change the tilt angle of the lower deflector 5.

[0028] The sensor assembly includes a first temperature sensor 6, a second temperature sensor 7, a third temperature sensor 8, and a door magnet 9. The first temperature sensor 6 is positioned close to the bottom of the freezer's glass door. The second temperature sensor 7 is positioned at the air outlet of the deflector assembly. The third temperature sensor 8 is positioned next to the evaporator 2, and the door magnet 9 is positioned on the freezer door. These three temperature sensors, located at different positions inside the freezer, can comprehensively sense changes in temperature within the freezer, while the door magnet 9 can promptly detect the freezer door opening and closing signals.

[0029] The temperature control structure of this utility model collects the door opening and closing signals of the freezer through the door magnet 9 during operation and transmits the signals to the prediction module in the processor through the Internet of Things system for training and learning. Based on the prediction results and the detection results of multiple temperature sensors in the freezer, the processor sends control signals to the thermostat and the deflector controller 41. The thermostat adjusts the parameter settings, and the deflector controller 41 adjusts the tilt angle of the lower deflector 5, thereby maintaining the uniformity and stability of the temperature inside the freezer.

[0030] Furthermore, in this embodiment, the temperature control scheme of the freezer can be selected to be turned on or off during operation. When the temperature control scheme is turned off, the freezer normally controls the start and stop of the refrigeration system according to the output signal of the temperature sensor 8, and the angle of the deflector plate remains fixed by default. When the temperature control scheme is turned on, the temperature inside the freezer is controlled and adjusted according to the temperature control structure of this utility model.

[0031] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
