Abstract
The utility model discloses an indoor temperature controller. The indoor temperature controller comprises a temperature controller housing, a processing circuit arranged inside the temperature controller housing, a first temperature sensor and a second temperature sensor both connected with the processing circuit and a comparison circuit connected with the processing circuit. The first temperature sensor and the second temperature sensor are respectively electrically connected with the comparison circuit. The first temperature sensor is arranged inside the temperature controller housing and adjacent to the processing circuit. The wall of the temperature controller housing is provided with a small hole where the second temperature sensor is located. The indoor temperature controller provided by the utility model has a simple structure. The first temperature sensor is arranged inside the temperature controller housing and adjacent to the processing circuit. The second temperature sensor is arranged inside the small hole of the temperature controller housing. The first temperature sensor and the second temperature sensor are both connected with the comparison circuit. By adopting the above-mentioned structure, the indoor temperature controller can precisely detect the indoor temperature change and minimize the influence of the heat generated by electronic components inside the housing on the temperature sensors. The indoor temperature controller enables high detection accuracy.
Description
Technical field
The utility model belongs to indoor thermostat.
Background technology
Indoor thermostat is a kind of indoor temperature to be measured and device to according to temperature equipment being regulated, its temperature-sensing element is a kind of to be NTC thermistor or the high platinum resistance of precision, but when temperature detector is surveyed indoor temperature, not only relevant with the temperature-sensitive components and parts, but also can be subjected to the impact of the factors such as circuit, structure, environment for use, can make the temperature of measurement relevant larger with actual indoor temperature, make it can accurately not detect the variation of indoor temperature.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, high indoor thermostat of detection indoor temperature degree of accuracy.
The technical scheme that realizes the utility model purpose is a kind of indoor thermostat, comprise temperature controller case, be arranged on treatment circuit, the first temperature detector that links to each other with treatment circuit and the second temperature detector in the temperature controller case, also comprise the comparator circuit that links to each other with treatment circuit, described the first temperature detector, the second temperature detector link to each other with described comparator circuit electricity respectively, described the first temperature detector be arranged in the temperature controller case by the treatment circuit place, the body wall of described temperature controller case is provided with an aperture, and described the second temperature detector is arranged in the described aperture.
Described aperture is arranged on the bottom of described temperature controller case, and becomes outside horn-like setting, described treatment circuit to be arranged on the interior top of described temperature controller case.
Top and the bottom of described temperature controller case are provided with air vent.
The utlity model has positive effect: treatment circuit place simple in structure, in temperature controller case of the present utility model is provided with the first temperature detector, is provided with the second temperature detector in the aperture of temperature controller case, the first temperature detector, the second temperature detector link to each other with comparator circuit, adopt this structure, can detect accurately the variation of indoor temperature, make the impact that the MIN heating that has reduced electronic devices and components in the housing causes temperature detector when detecting indoor temperature, it is high to detect degree of accuracy; And aperture becomes outside horn-like setting, increased and the indoor area that contacts, improved the validity that indoor temperature is detected, and the utility model is arranged on treatment circuit at the top of housing, the second temperature detector is arranged on the bottom of temperature controller, and be equipped with air vent in case top and bottom, owing between its top and bottom certain distance is arranged, can effectively reduce in the treatment circuit electronic devices and components heating impacts the second temperature detector, improved the precision that indoor temperature is detected, practicality is good.
