Abstract: An image construction method and system for a heating area is provided. The method includes: obtaining an initial image according to a heating structure diagram and a building structure diagram of the heating area; segmenting the initial image according to heating attribute of the heating area to obtain a plurality of segmentation sub-graphs; performing first collection on a surface temperature of a heating pipeline according to pre-deployed surface devices corresponding to the segmentation sub-graphs, and setting first heating labels corresponding to the segmentation sub-graphs, and meanwhile, performing second collection on a regional temperature of a sub-area of the heating pipeline being located according to a pre-deployed monitoring device corresponding to the segmentation sub-graphs, and setting second heating labels; performing position and temperature analysis on a label setting result of each of the segmentation sub-graphs to obtain a heating image of the heating area.

Abstract: A ventilating fan including a ventilating fan body provided with a motor, a frame having ventilating air outlets, and fan blades, an adapter and an electric element box. The ventilating air outlets include a top air outlet provided on a top face of the frame of the ventilating fan and a side air outlet provided on a side face of the frame of the ventilating fan which are communicated with each other. The adapter is provided with a raised structure adapted to the ventilating air outlet. With this structure, the height of the ventilating fan is reduced while air volume is ensured, so that the ventilating fan is adapted to be mounted onto various ceilings, and the cost can be saved while mounting of the adapter is simplified.

Abstract: A heating ventilator for bathroom includes a frame, a motor mounted with fan blades, a volute casing, an air path switching plate located at the air outlet of the volute casing for switching the air outlet of a ventilator main body, a heater, and a control electric circuit mechanism for operating the motor, the air path switching plate and the heater. The air path switching plate and the heater are configured in a separate and overlapping manner in the height direction of the ventilator main body. The center line of the fan blades and a tongue of the volute casing are both offset from the center line of the main body and are located at the same side. The center line of the main body is horizontally aligned and overlapped with the center line of the air path switching plate and the center line of the heater.

Abstract: A heating and ventilation fan for a bathroom comprises an ventilation fan frame, a scroll casing provided with fan blades and a motor, an air passage-switching plate, and a heater; characterized in that: an air leakage-preventing structure is provided between an air outlet of the scroll casing and the air passage. The advantage of the present invention is that a desired air amount can be ensured and a noise can be reduced while guaranteeing a gap required for smooth rotation of the air passage-switching plate.

Abstract: A heating and ventilating fan including a frame, a motor with fan blades, a casing, a heating device, and an air path switching plate disposed at an air outlet of the casing for switching outlets of the ventilating fan and a timing motor. The timing motor and the air path switching plate are fixed on either side of a frame wall. The air path switching plate is connected to the timing motor shaft through a connection part, and controls the air path switching plate to rotate by a constant angle in a single direction. A spring having a first end fixed to the frame wall, and a second end rotating synchronously with the air path switching plate controls the air path switching plate to rotate in an opposite direction to the single direction. When the timing motor is switched off, the spring returns the air path switching plate to its rest position.

Abstract: A ventilating fan for heating, includes a main body frame provided with an opening, a fan casing provided with a fan therein, a heater assembly fixed at an air outlet of the fan casing and a thermostat for detecting an indoor temperature, and the thermostat is embedded in an air-passageway wall.
