Inner compartment temperature detecting device for automatic air conditioning of automobile

Abstract

A compartment temperature detection device for automatic air-conditioning of automobiles, comprising an air-conditioning control panel, a rear casing of the air-conditioning control panel and a temperature sensor, an air connecting pipe is arranged in the rear casing of the air-conditioning control panel, and the inner cavity of the air connecting pipe is connected to the air-conditioning The inner cavity of the rear shell of the control panel is isolated, the front end of the air connecting pipe is opened in the air conditioner control panel, the rear end is opened in the rear end surface of the rear shell of the air conditioner control panel, a fan is arranged at the rear end opening, and the temperature sensor is arranged in the air connection in the lumen of the tube. The invention utilizes an independent air connecting pipe and fan to extract the air in the compartment, and uses a temperature sensor installed in the air connecting pipe to detect the temperature of the air therein, which can accurately measure the temperature in the compartment and improve the temperature control effect. At the same time, the air connecting pipe can also isolate the contact between the hot air in the compartment and the electronic board / electronic components, so as to ensure the reliability of the electronic components.

Description

Technical field: [0001] The invention relates to the field of automobiles, in particular to a control technology of an automobile air conditioner, in particular to a temperature detection device used for an automobile automatic air conditioner in a compartment. Background technique: [0002] The air conditioning system is used in the car compartment to provide a comfortable temperature environment. Automobile air conditioner is automatically controlled by ECU (Electronic Control Unit), which can automatically adjust the outlet air temperature according to the temperature of the cabin, and has the functions of smooth compliance and fine temperature control adjustment. The air-conditioning control part ECU is connected with a temperature sensor in the vehicle compartment, and the temperature sensor in the vehicle compartment detects the temperature inside the vehicle compartment. However, in the prior art, the temperature sensor in the compartment is installed behind the air-...
