Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically to a temperature and humidity pre-embedded box and the refrigerator thereof. Background Technology

[0002] With the widespread use of variable frequency compressors and variable frequency fans, refrigerators and ice bars all need ambient temperature sensors to detect changes in ambient temperature and control the speed of compressors and fans based on the ambient temperature, thereby achieving functions such as dual frequency conversion energy saving and rapid cooling.

[0003] Existing temperature and humidity sensors are usually directly attached to the back panel of the refrigerator. However, this installation method has the following drawbacks: 1. Since the temperature sensor is installed inside the foam layer on the back of the back panel, it needs to be broken and dug out for repair, which is inconvenient; 2. Since the back panel of the refrigerator is metal and has condenser pipes attached to it, the temperature of the back panel will affect the detection accuracy of the temperature sensor, making it impossible to accurately detect the air temperature.

The box body 11 is installed on the back plate 21 and extends to the inside of the back plate 21. The box cover 12 is installed at the opening of the box body 11. When it is necessary to replace and repair the sensor, the box cover 12 can be removed to expose the sensor inside the box body 11, which is convenient for the later maintenance or replacement of the sensor.

[0017] Inside the housing 11, an ambient temperature sensor 15 and a temperature and humidity sensor 16 are sequentially mounted from top to bottom. A vertical partition 19 is located below the temperature and humidity sensor 16 inside the housing 11. A condensation chamber is formed on one side of the partition 19, and a circulation chamber is formed on the other side. The probe of the ambient temperature sensor 15 is connected to the circulation chamber, and the probe of the temperature and humidity sensor 16 is connected to the condensation chamber. By setting up a pre-embedded box 10 structure, the ambient temperature sensor 15 and the temperature and humidity sensor 16 are integrated inside the pre-embedded box 10, avoiding direct contact between the sensors and the metal backplate. The partition 19 connects the condensation chamber and the circulation chamber inside the housing 11. The condensation chamber is connected to the air cooled by the refrigerator's condenser pipe, and the circulation chamber is connected to the ambient air surrounding the refrigerator. The ambient temperature sensor 15 can detect the temperature of the environment surrounding the refrigerator, and the temperature and humidity sensor 16 can detect the temperature and humidity of the air cooled by the condenser pipe.

[0018] Furthermore, the ambient temperature sensor 15 is used to detect the temperature information of the environment in which the refrigerator is located, and then converts the detected temperature information into an electrical signal and uploads it to the refrigerator's built-in controller, so that the controller can obtain the temperature information of the environment in which the refrigerator is located; the temperature and humidity sensor 16 is used to detect the air temperature and humidity after the condenser tube has cooled down, and then converts the detected temperature and humidity signals into electrical signals and uploads them to the refrigerator's built-in controller, so that the controller can obtain the temperature and humidity information after the refrigerator's own condenser tube has cooled down.

[0019] The lid 12 has a circulation vent 14 on one side of the circulation chamber, which ensures that the air in the circulation chamber is connected to the air in the refrigerator's surrounding environment. The air in the refrigerator's surrounding environment can enter the circulation chamber through the circulation vent 14, ensuring that the ambient temperature sensor 15 can detect the temperature information of the refrigerator's surrounding environment. The bottom of the box 11 has a wiring hole 13 on one side of the condensation chamber, which ensures the wiring of the ambient temperature sensor 15 and the temperature and humidity sensor 16. It also ensures that the condensation chamber is connected to the cooling area of ​​the condenser pipe 22, ensuring that the air in the cooling area of ​​the condenser pipe 22 can enter the condensation chamber, and that the temperature and humidity sensor 16 can detect the temperature and humidity of the air after the condenser pipe has cooled down.

[0020] The housing 11 has a first slot 17 located at the top inside, where the ambient temperature sensor 15 is snapped into. Two symmetrical first elastic clips 171 are located on both the upper and lower sides of the first slot 17, securing the ambient temperature sensor 15 within the slot 17. The cooperation of the first slot 17 and the first elastic clips 171 secures the ambient temperature sensor 15 within the housing 11, facilitating its installation and removal. When the ambient temperature sensor 15 needs replacement or repair, simply levering the first elastic clips 171 removes it from the slot 17, greatly improving maintenance convenience. The first elastic clips 171 are made of TPE plastic.

[0021] Inside the housing 11, a second slot 18 is located below the first slot 17. The temperature and humidity sensor 16 is snapped into the second slot 18. A support plate is located on the lower side of the second slot 18, and a second elastic buckle 181 is located on the upper side of the second slot 18. The temperature and humidity sensor 16 is secured in the second slot 18 by the second elastic buckle 181. The support plate supports the temperature and humidity sensor 16, and the second elastic buckle 181 securely snaps the temperature and humidity sensor 16 into the second slot 18, facilitating the installation and removal of the temperature and humidity sensor 16. When it is necessary to replace or repair the temperature and humidity sensor 16, simply pull the second elastic buckle 181 to remove the temperature and humidity sensor 16 from the second slot 18, greatly improving the convenience of maintenance. The second elastic buckle 181 is made of TPE plastic.
