Description
Technical field
This utility model is related to intelligent heating application, specifically a kind of switching mode room thermostat.
Background technology
Winter northern area adopts the mode of central heating to provide the indoor temperature ensured needed for life for resident family.With near
Urbanite's house amount increases over year, while being on the rise by the atmospheric pollution caused for factors such as hot drivings, takes effectively
Energy-saving and emission-reduction mode become instantly heat work the most important thing.
Collective's heating method on present society more than heating system using extensive style, in man of resident family to the requirements of room temperature not
Effectively collection can be obtained and utilized.Simultaneously resident family cannot effectively be closed to heat supply pipeline automatically according to oneself practical situation
Close and open operation, cause without the need for during heat supply, equally consuming amount of heat in resident family, while heat supply company cannot be according to resident
In existing house actual temperature value come adjust heating amount number, cause the significant wastage of resource.
The installation of existing room thermostat, needs another punching fixed installation or threading on wall, and to metope one is caused
Fixed destruction, needs, to metope reparation, to need more manpower and materials.Also some special users, not in wall or
Punching in other positions is fixed, and can be only placed at a certain position of interior, easily mobile, if being put near heating sources, is easily caused and is set
The standby temperature for collecting is too high, makes on-off controller close valve, causes the temperature of interior lower than the temperature for setting.Existing room
Temperature controller is powered with battery, battery electric quantity can be caused not enough without replacing in time, artificially removes battery, battery loose contact etc.
Battery reason, does not collect the temperature data of interior, it is impossible to which on-off controller is controlled, it is impossible to realize adjusting indoor temperature
Section.
