Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, specifically to a vehicle refrigerator temperature measuring device and a vehicle refrigerator. Background Technology

[0002] Currently, refrigerators have formed a large-scale industrial structure in my country, and their design and manufacturing have reached international leading levels. Traditional refrigerators typically control temperature through the refrigerator compartment. The different temperatures of the refrigerator and freezer compartments are achieved by adjusting the area of ​​the evaporator in each compartment, with temperature regulation entirely dependent on the compressor's operation. However, the temperature inside a refrigerator is affected by many factors, such as the initial temperature of the items placed inside, the heat dissipation characteristics and heat capacity of the stored items, the degree to which the refrigerator is filled, the ambient temperature, and the frequency of door opening. Therefore, the integrated refrigerator temperature measurement device currently used cannot effectively measure localized temperature changes within the refrigerator, leading to errors in temperature adjustment during actual use.

[0003] For example, the utility model patent with authorization announcement number CN213180129U discloses a wireless temperature and humidity probe for monitoring the temperature of a medical refrigerator. This device, by setting up a receiver, a wireless communication module and a circuit board, can remotely control the temperature and humidity probe via the network, avoiding the inconvenience of using the medical refrigerator due to the slow operation and monitoring speed of the probe, and improving the efficiency of using the temperature and humidity probe for monitoring the temperature of a medical refrigerator.

[0004] However, in actual use, when the temperature-measuring thermistor is damaged, it needs to be replaced by removing the screws, which is a cumbersome operation, reduces maintenance efficiency, and cannot well meet the usage requirements. Utility Model Content

[0026] The working principle of this utility model is as follows: During installation, the connecting stud 14 at the end of the temperature sensor 12 is aligned with the threaded groove 17. Then, the temperature sensor 12 is rotated so that the connecting stud 14 is screwed into the threaded groove 17, thus completing the installation. The operation is simple and convenient for disassembly and assembly, which can better meet the needs of use.

[0027] As a further embodiment, the conductive component includes a conductive groove 18 formed within a threaded groove 17, a conductive contact 19 installed within the conductive groove 18, and an elastic conductive pin 15 installed at the end of the connecting stud 14, the elastic conductive pin 15 contacting the conductive contact 19. In this embodiment, the conductive contact 19 is electrically connected to the control module.

[0028] The working principle of the conductive component is as follows: During installation, as the connecting stud 14 is inserted into the threaded groove 17, the elastic conductive pin 15 moves and comes into contact with the conductive contact 19, thereby realizing the connection between the temperature sensor 12 and the control module in the control body 1.

[0029] The control module is electrically connected to the display screen 11 and the temperature sensor 12.
