Abstract

The utility model provides an automatic temperature control safety multipurpose electric heating apparatus, composed of a box type casing, heating grates and support legs. Non-fire electric heating elements and dual temperature control elements are arranged in the box body. When the utility model is used, a quilt for roasting is covered on the heating grates and the hand or foot can extend into the quilt. During baking clothing, the clothing can be covered on the heating grates directly. The temperature in the box can be maintained automatically within a definite temperature range after the power is switched on. When the temperature in the box exceeds the control temperature, the overheat switch can automatically cut off the power source and emit an alarm sound. The device has the advantage of low power consumption and can bring convenience for heating in winter and drying clothing in rainy season.

Description

Temperature automatically controlled safety multi-purpose electric heating device
The device that the utility model provides a kind of heating and drying to use.
Winter, people used the electric heating device of various types to solve cold problem; especially cotton-wadded quilt heating the many local people's customs in south are warmed oneself by a fire bung with van-type on; but some electric heating device that uses does not have temperature control and overheat protective function at present; be placed on heating in the wooden bucket of warming oneself by a fire; power consumption is big, and carelessness is arranged slightly, is prone to accidents; therefore, warming is sought after a kind of safe, convenient, simple in structure, electric heating device that power consumption is low.
The purpose of this utility model is to have realized a kind of van-type safety multi-purpose electric heating device.This device is safe and reliable, and power consumption is low, and heat energy utilization rate height uses adjustable height, has temperature automatically controlled and overheat protective function.And cost is low, and long service life is convenient to promote.
Main points of the present utility model are: this warmer includes van-type insulation crust, support foot and electrical heating automatic temperature control circuit.The van-type insulation crust includes envelope and heating grid, and useful four support foots that are threaded in envelope bottom are pulled down support foot and can be placed on the beneath heating of desk.The electric heating wire and the automatic temperature control circuit of the flames of anger is equipped with in envelope inside; when temperature in the railway carriage or compartment reaches the control temperature; the thermostat action; stop heating; when temperature in the railway carriage or compartment was lower than the control temperature, thermostat was connected heater circuit automatically, so repeatedly circulation automatically; when temperature surpasses the control temperature in the railway carriage or compartment, the overheat switch double protection of will having cut off the electricity supply automatically.
Be elaborated below in conjunction with accompanying drawing.
Fig. 1 is temperature automatically controlled safety multi-purpose electric heating device stereogram.
Fig. 2 is overheat switch and automatic temperature control device scheme of installation.
Fig. 3 is automatic temperature control circuit figure.
As Fig. 1, Fig. 2, shown in, this temperature automatically controlled safety multi-purpose electric heating device is by envelope 1, heating grid 2, support foot 11 and heating automatic temperature control circuit are formed.Heating grid 2 is screwed on installing plate 4; porcelain knob 16 has been screwed below the installing plate 4; heating wire 3 in porcelain knob 16 grooves, be evenly distributed on the heating grid 2 below; be screwed block 17 on four jiaos of the medial surfaces of envelope 1; heating grid 2 with put into envelope 1 usefulness screw after installing plate 4 connects and be fastened on the block 17; on the plate of the railway carriage or compartment, side of envelope 1, have several apertures; green power supply indication luminous tube 5 outwards is installed from the lining; pipe 6 is sent out in red heating indication; power switch 15; temperature automatically controlled actuator temperature is set turn-knob 14; overheat alarm 7; medial surface at envelope 1 is equipped with temperature sensing scissel 18, and automatic temperature control device 20 and overheat switch 19 all are installed on the temperature sensing scissel 18.With screw four support foot fixed heads 10 and four plastic foots 13 are installed on four jiaos of the bottoms of envelope 1, support foot 11 lower ends are with plastic sheath 12.The upper end has screw thread to be used for being connected with block 17, pulls down support foot 11, this warmer can be placed on to warm oneself below the desk, loads onto support foot 11, then can be used for being sitting in seeing on the sofa that TV warms oneself.
As shown in Figure 3; the heating and automatic temperature control circuit by plug 8, power line 9, switch 15; overheat switch 19; overheat alarm 7, automatic temperature control device 20, heating wire 3; green power supply indication luminous tube 5; red heating indication luminous tube 6, temperature sensing scissel 18, temperature automatically controlled actuator temperature are set turn-knob 14 and are formed.
During use; the cotton-wadded quilt of warming oneself by a fire is covered on heating grid 2; connect power switch 15; electric current is through the normally-closed contact of overheat switch 19 and automatic temperature control device 20; heating wire 3 gets electric, the heating beginning, and power supply is indicated luminous tube 5 and heats indication luminous tube 6 simultaneously luminous; when reaching the control temperature; automatic temperature control device 20 normally-closed contacts disconnect, and heating stops, and luminous tube 6 extinguishes; luminous tube 5 continues luminous expression and is in keeping warm mode; when temperature in the railway carriage or compartment drops to the following certain numerical value of control temperature gradually, automatic temperature control device 20 normally-closed contact closures, heating indication luminous tube 6 is luminous; heating restarts, so automatically circulation.When temperature is higher than the highest control temperature of automatic temperature control device in unexpected envelope 1 occurring; overheat switch 19 normally-closed contacts are cut off the electricity supply automatically; simultaneously; be connected in parallel in overheat alarm 7 access circuits at overheat switch 19 normally-closed contact two ends; sound, reminds people is in time handled, after overheat switch 19 normally-closed contacts disconnect; though overheat alarm 7 is serially connected in the heater circuit, because of in the overheat alarm 7 current-limiting apparatus being housed.So, can not make heating wire 3 continue heating.Therefore, this device has the duplicate protection warning function.
