Abstract

The utility model belongs to an electric heating appliance, which is a portable auto-controlled heater which is especially suitable for the health care of a human body. An auto-controlled heating circuit in the heat storing box body of the heater is mainly composed of an electric heating load and a ceramic temperature relay; after a thermal-insulation protective coating is allocated, and thus the heat storing box body which is made of non-metallic material has small volume and light weight.

Description

Auto-controlled air heater

The utility model belongs to electric heating appliance, is a kind ofly to be particularly suitable for body-care with portable automatic control warmer.

At present to human body play the electric heating appliance of heating and hot compress effect more common under blanket, pad etc. are arranged, long-time and the electric power connecting of palpus during use, and scarcely dispose adjustment and switch control member, and be not suitable for going out to carry, can not play hot packing effect targetedly to the human body patient part.Though developed the warming article that to carry and to have automatic control heat accumulation function, but because of the circuit structure of its automatic control heating comparatively complicated, need more electronic devices and components, and how the shell of this class warming article is made with metal material, it is higher to exist cost, easily break down and safety inadequately when using, because of its volume weight more still is not easy to carry etc. not enough.

The purpose of this utility model is to provide a kind of automatic control warmer, automatic control heater circuit in this warmer heat accumulation box body is that the master constitutes by electrothermal load, ceramic temperature relay only, behind the configuration heat preservation protective layer, can make that heat accumulation box body volume is less, weight is lighter, the heat accumulation box body adopts nonmetallic materials to make in addition.So this automatic control warmer can overcome the existing in prior technology deficiency effectively.

Overall structure of the present utility model is:

A kind of automatic control warmer is to lead circuit of forming and the insulation that sticks on inboard wall of cartridge and overcoat 4,5 to constitute by heating 2, the temperature control component 3 of device in heat accumulation box body 1, and heating is made up of the refractory material housing 6 of load DR and encapsulation load; Load has certain power with a kind of the making in chrome-nickel, three kinds of materials of DZR, PTC; An end is connected with power supply after load DR and the electronic display elements D parallel connection, and the other end connects temperature control electronic switch WJ, and the other end of electronic switching device constitutes the automatic control heater circuit after connecting power supply; Two binding posts 7 and the electronic display elements D of power supply are installed on the shell wall of heat accumulation box, the housing of encapsulation electrothermal load DR is placed in the central part in the heat accumulation box body, conducting strip 8 is fastened on the outside wall surface of housing and temperature control electronic switch WJ crimping, the housing of thermal insulating layer 9 parcel DR, heat preservation protective layer 10 topped heat-insulation layers also stick on the internal face of heat accumulation box body.

Each components and parts apolegamy of forming the automatic control heater circuit is respectively:

Electrothermal load DR power is 300-500 watt, makes annular disk with chromium nickel resistance wire and puts in housing 6, and electronic display elements D is a light emitting diode, and temperature control electronic switching device WJ is that integral body is that the ceramic temperature relay of sheet, temperature coefficient are 100 ℃-150 ℃.

The architectural feature of each main member of warmer is:

Conducting strip 8 is fastened on the outer wall of housing by the bolt 11 of cross-under garden plate-like housing, the thermal storage device box body is by two housing butt joint assemblings that are plate-shape, its diameter is 130-150mm, average thickness is 30-70mm, makes with insulating materials such as phenoplasts, and the diameter of the housing of encapsulation load DR is 60-80mm, thickness is 10-25mm, thermal insulating layer 9 average thickness are 5-10mm, and heat preservation protective layer 10 average thickness are 15-35mm, make with alumina silicate, asbestos material respectively.

Accompanying drawing of the present utility model is as follows:

Fig. 1 is the circuit diagram of automatic control warmer.

Fig. 2 is the stereochemical structure view of automatic control warmer.

Accompanying drawing has provided embodiment of the present utility model, further specifies as follows in conjunction with the accompanying drawings:

It is 75mm around diameter that heating in this warmer heat accumulation box body can be done loading disk with chromenickel wire, in the thick garden plate-like housing of 20mm, its housing is made by conventional refractory material, also available PTC or DZR new electrically heating material are done load and are made the micro-electric heating element, and the thermorelay that is disposed is that volume only is 18 * 9 * 4mm ³The little stick of rectangle, the automatic control heater circuit volume that is constituted with light emitting diode is little, temperature design that can be as required, apolegamy heating, thermostat relay are made the less nonmetal heat accumulation box body of volume.Thermorelay with 100 ℃ ± 5 ℃ of specifications, electrothermal load power is that 300-500 watt warmer is an example, the diameter of nonmetal heat accumulation plate-shape box body only is 140mm, average thickness is about 50mm, all the other are as power-line terminal, the hole of light emitting diode is installed, and is spread deposited each heat preservation protective layer and also easily arrange and make (as shown in Figure 2), overall weight is no more than 500 and restrains.In addition, the performance of this warmer is also practical stable, with power is that 300 watts warmer is an example, connected 200 volts of alternating currents 5 minutes, can reach temperature required, heating can be warming up to about 80 ℃ in the box body, conducts heat by relay control auto power off by conducting strip, the skin temperature of thermal storage device box body is 40-50 ℃, and can keep about 3 hours under 15-20 ℃ the environment temperature.

The obtained technological progress of the utility model is:

This auto-controlled air heater can heat up with electrothermal device according to the temperature of user's needs, by the break-make of the automatic control of temperature relay with power supply, is aided with two-layer insulation, protective materials again, can Automatic control heat accumulation, its temperature can keep the long time. This just can effectively utilize warmer and warm oneself, and can carry out hot packing to the patient part of human body needs thermotherapy according to heat radiation principle. Both be convenient to people and carried, warmed oneself season at cold weather, had again the effect of certain promoting health and curing diseases. A kind of easy to use, simple and light and safety durable, lower-cost desirable warming article.
