Temperature detection device in a kind of compartment that is used for the automobile automatic air condition
Technical field:
The present invention relates to automotive field, relate in particular to the control technology of air conditioning for automobiles, temperature detection device in particularly a kind of compartment that is used for the automobile automatic air condition.
Background technology:
Adopt a/c system that comfortable temperature environment is provided in the automobile bodies.Air conditioning for automobiles adopts air-conditioning function unit ECU (Electronic Control Unit) to carry out automatic guidance, can have level and smooth compliance according to compartment temperature automatically regulating leaving air temp, and meticulous function is regulated in temperature control.Air-conditioning function unit ECU is connected with temperature sensor in the compartment, and temperature sensor is surveyed the compartment temperature inside in the compartment.But; In the prior art, temperature sensor is installed in the rear of air-conditioning panel in the compartment, contiguous air-conditioning function unit ECU; And there is air-conditioning panel to isolate between the air in a car compartment; Therefore the temperature that records receives the warming-up effect of electronic component among the air-conditioning function unit ECU easily, the temperature conditions in can not the accurate response compartment, and it is bad to cause air-conditioning to control effect
Summary of the invention:
The object of the present invention is to provide temperature detection device in a kind of compartment that is used for the automobile automatic air condition, temperature detection device will solve the technical matters that temperature sensor is influenced by the nearby electron element heating easily in the prior art compartment in the described this compartment that is used for the automobile automatic air condition.
Temperature detection device in this compartment that is used for the automobile automatic air condition of the present invention; Comprise Air-Conditioning Control Panel, Air-Conditioning Control Panel rear housing and temperature sensor; Wherein, be provided with an air connection pipe in the described Air-Conditioning Control Panel rear housing, the inner chamber of the inner chamber of described air connection pipe and Air-Conditioning Control Panel rear housing is isolated; The front opening of air connection pipe is in described Air-Conditioning Control Panel; The open rearward end of air connection pipe is in the aft end face of Air-Conditioning Control Panel rear housing, and the open rearward end place of air connection pipe is provided with blower fan, and described temperature sensor is arranged in the inner chamber of air connection pipe.
Further, be provided with air grid in the described Air-Conditioning Control Panel.
Further, be provided with first tightening seal washer between the front end of described air connection pipe and the Air-Conditioning Control Panel.
Further, be provided with the electron steering plate in the Air-Conditioning Control Panel rear housing, described temperature sensor is connected with described electron steering plate through signal conductor, is provided with second tightening seal washer between air connection pipe and the electron steering plate.
Further, the front end of described air connection pipe is through last positioning bar and Air-Conditioning Control Panel clamping, and the rear end of air connection pipe is connected on the electron steering plate through following positioning bar.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention utilizes independently that air connection pipe and blower fan extract the air in the compartment, utilizes the temperature sensor that is arranged in the air connection pipe to detect air themperature wherein, can accurately measure temperature in the compartment, the raising temperature control effect.What simultaneously the air connection pipe can also have been isolated hot blast and electron plate/electronic devices and components compartment the in contacts the reliability of assurance electronic component.

The specific embodiment:
Embodiment 1:
Like Fig. 1, Fig. 2 and shown in Figure 3; Temperature detection device in a kind of compartment that is used for the automobile automatic air condition of the present invention; Comprise Air-Conditioning Control Panel 1, Air-Conditioning Control Panel rear housing 5, electron steering plate 8, display panel 9 and temperature sensor 2, the signal output part of temperature sensor 2 is connected with electron steering plate 8, is provided with air grid 11 in the Air-Conditioning Control Panel 1; In Air-Conditioning Control Panel rear housing 5, be provided with air connection pipe 4; The open rearward end place of air connection pipe 4 is provided with air suctiton ventilator 7, and the front opening of air connection pipe is provided with first tightening seal washer 3 in Air-Conditioning Control Panel 1 between air connection pipe 4 and the Air-Conditioning Control Panel 1; Air connection pipe 4 is passed on the electron steering plate 8; Be provided with second tightening seal washer 6 between air connection pipe 4 and the electron steering plate 8, the front opening of air connection pipe 4 communicates with air in a car compartment through the air grid in the Air-Conditioning Control Panel 1 11, and temperature sensor 2 is positioned at air connection pipe 4.
Further, the front end 42 of air connection pipe 4 is through last positioning bar 41 and Air-Conditioning Control Panel 1 clamping, and the rear end 44 of air connection pipe 4 is connected on the electron steering plate 8 through following positioning bar 43.
Concrete, when air suctiton ventilator 7 began to rotate, the air the compartment in got in the Air-Conditioning Control Panels 1 through the air grid in the Air-Conditioning Control Panel 1 11 smoothly, along air connection pipe 4 through 7 compartment air exhaustion that are drawn into of blower fan.Behind the air admission Air-Conditioning Control Panel 1 in the compartment; Temperature sensor 2 can be sensed the air themperature in the compartment that is drawn into accurately; The temperature feedback information that this moment, air-conditioning function unit ECU can detect according to temperature sensor; Regulate leaving air temp accurately, reach meticulous temperature control effect.Independent air by-pass passage has avoided the hot blast in the compartment to contact with electron plate and electronic devices and components, has improved the reliability of electronic product.
