Abstract
The utility model relates to an electric warming machine which is composed of an outer housing, an electric heating body, a fan and a control circuit. The utility model is characterized in that a timer and an automatic temperature controller are arranged in the control circuit. The utility model has the functions of timing and constant temperature control and has the advantage of convenient operation. An overtemperature protecting device is also arranged in the circuit for ensuring use safety. The warming machine of the utility model can be used for heating in winter, can be used as the fan in summer, and can also be used for drying clothing.
Description
The utility model relates to a kind of electric heater machine.
Existing electric heater machine generally is made of shell, electric heating body, fan and control circuit, its control circuit just comprises the conversion of heater power and fan swicth and power switch, so can only play switching on and shutting down and change the heating power size, timing and thermostatic control function do not use inconvenience.And existing electric heater machine does not have the overtemperature prote function, in case fan breaks down and do not work and heater is still worked, built-in temperature will raise rapidly, cause body to burn out easily and the accident that meets accident.
The purpose of this utility model provides a kind of warming machine with timing and thermostatic control and overtemperature prote function, to overcome the existing shortcoming of prior art.
Warming machine of the present utility model is made of shell, electric heating body, fan and control circuit.Electric heating body is formed in parallel by a plurality of heatings.Control circuit is connected with fan swicth, temperature automatic control switch and timer by the power conversion and is constituted.Power conversion and fan swicth adopt multitool multiple contact switch, and each contact is connected with fan with each heating respectively, by the disconnection or the closed power conversion and the cold and hot air control function of realizing of different contacts.
Timer preferably adopts electrodynamic timer.
Also can be connected in series the overtemperature prote device in control circuit, when breaking down owing to fan or other reason when causing that built-in temperature is too high, the overtemperature prote device is protected parts automatic shutdown circuit, and can prevent contingency.
Warming machine of the present utility model is owing to be equipped with timer and temperature automatic control switch in circuit, thus have regularly and the thermostatic control function, very convenient to use.Simultaneously, also, can guarantee the safety of using owing to be serially connected with the overtemperature prote device in the circuit.The shell back side is provided with the wall built-up structure, both can make a formula and use, also can do the wall-hanging use.
Warming machine of the present utility model can be made fan summer and use for heating winter, also can make dryer usefulness, but drying clothes.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the circuit diagram of a kind of embodiment of the utility model.
With reference to Fig. 1, electric heating body is made of heating 1 and 2 parallel connections, power conversion and fan swicth 4(are hereinafter to be referred as switch 4) be four blade four switch contacts, the a of switch 4, b, four moving contacts of c, d are connected with an end of heating 1, indicator lamp 9, heating 2 and fan 3 respectively, and the deciding of switch 4 is serially connected with timer 5 between contact and the power supply; Be serially connected with temperature automatic control switch 6, temperature fuse 7 and temperature relay 8 between the other end of heating 1,2 and fan 3 and the power supply; both constitute the overtemperature prote device back; when built-in temperature reaches 85 ℃; temperature relay 8 will be cut off the electricity supply automatically; when built-in temperature reaches 115 ℃; temperature fuse 7 promptly disconnects cuts off the electricity supply, and reaches double protection functions.Temperature automatic control switch 6 is a bimetal release, with switch 4 coaxial interlocks, rotates the disconnected temperature of closing that changes bimetal leaf by helical axis, thereby reaches the purpose of automatic control warm-air drier operating temperature.The temperature control scope of temperature automatic control switch 6 is about 15 ℃～35 ℃.Switch 4 is controlled by a rotating shaft, can realize four kinds of state of a controls: first kind is that four groups of dynamic/static contacts all are in the disjunction state, and complete machine is in off-mode; Second kind is that moving contact b is in closure state, a and c and is in the disjunction state, make fan 3 and indicator lamp 9 and power supply constitute path, and heating is not worked, and forms the cool breeze duty; The third is to increase by one group of dynamic/static contact closure on second kind of state basis, makes a heating job, and another heating is not then worked, and forms the warm braw duty; The 4th kind is that four groups of dynamic/static contacts are all closed, and two heatings are all worked, and form the hot blast duty.In the process of above four kinds of states, temperature automatic control switch 6 is in closure state all the time, does not work, when the helical axis of switch 4 continues to be threaded to the temperature control position, switch 4 keeps the 4th kind of state, and temperature automatic control switch 6 is subjected to the effect of helical axis and in running order; This moment if temperature be lower than control temperature then switch 6 be in closure state, make complete machine work; If temperature is higher than the control temperature, then switch 6 is in off-state, the complete machine break-off, and when environment temperature is lower than the control temperature, switch 6 auto-closings, complete machine is resumed work.Timer 5 is an electrodynamic timer, makes motive power by stepper motor and controls a pair of power supply main contact time-delay disconnection through the transmission of multi-stage gear speed change.Adopt electrodynamic timer to be more suitable for, and it is big to have the timing scope, easily operation (but rotating) and advantage such as regularly accurately stablize in high-power circuit.Heating 1 and 2 adopts heating wire to bend to the circle out shape, and riveting constitutes electric heating body on micarex, can guarantee that heating evenly; Heater and fan are on the same axis, make heater all be in the high wind convective region, can improve heater service life and heat transference efficiency.
