Abstract

The utility model discloses a far infrared hand-heating stove, comprising a casing (1) and a loop. The casing (1) is provided with a heat accumulator (2) and an electric heating body (3), and the loop is formed by that the electric heating body (3) and a temperature controller (4) which are connected in serially are connected with a power supply. The outer surface of the heat accumulator (2) has a far infrared coat (6); a resistor (7) and an indicating light (8) are connected in parallel between the temperature controller (4) of a small-size ceramic closed type normally-closed contact and the electric heating body in a main circuit; a heat insulator (5) is arranged between the casing (1) and the heat accumulator (2) which is arranged in the middle of the inner side of the casing (1). The utility model has the advantages of simple structure, low power consumption, convenient carrying, stable temperature, practicability and reliability, and the continuous holding time can reach to two to three hours after the power supply is cut off.

Description

Far infrared hand-heating stove

The utility model relates to a kind of electric heating installation, particularly a kind of far infrared hand hand warmer.

The apparatus of warming mostly is the container of hot-water flooding at present, fast, use trouble that not only easy to leak, and heat scatters and disappears.The utensil that adopts the electricity heating is also arranged in recent years, of a great variety, and the big appearance and size of power is big, generally all will adopt temperature control component, as expansion alloy, bimetallic thermoswitch etc., mostly exposes outside, and element is malfunctioning easily easily causes danger.The warmer that yet has does not have heat insulation function, and outage back temperature descends rapidly, and is very inconvenient during use.

The purpose of this utility model provides that a kind of simple in structure, low in energy consumption, temperature retention time is long, temperature stabilization, far infrared hand hand warmer easy to carry.

The utility model is realized by following measure:

A kind of far infrared hand hand warmer, comprise and have heat storage (2) in the housing (1), electric heating body (3) and with electric heating body (3), the loop of forming with power supply after temperature controller (4) is in series, between the heat storage (2) that housing (1) and its bosom position have thermal insulator (5) is housed, the outer surface of heat storage (2) has far infrared coating (6), can produce far-infrared thermal radiation, temperature controller (4) is the closed normally-closed contact of small-sized pottery, and a resistor in parallel (7) and indicator lamp (8) carry out state and show between electric heating body in main circuit (3) and the temperature controller (4).Thermal insulator (5) adopts the alumina silicate fibre material.The material manufacturing that heat storage (2) adopts carborundum, zircon sand and clay to form.The interior both ends of the surface of housing (1) middle part is provided with metal derby (9).The material manufacturing that heat storage (2) also can adopt rare earth element, zircon sand and clay to form.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a circuit structure diagram of the present utility model;

Fig. 3 is the far infrared hand hand warmer structure chart with metal derby;

Among the figure: (1) housing, (2) heat storage, (3) electric heating body,

(4) temperature controller, (5) thermal insulator, (6) far infrared coating,

(7) resistor, (8) indicator lamp, (9) metal derby,

(10) socket, (11) secondary flexible circuit conductor, (12) plug,

(13) micarex, (14) screw.

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment 1 as shown in Figure 1, has heat storage (2) in the metal material housing (1) of far infrared hand hand warmer, electric heating body (3) and with electric heating body (3), the loop of forming with power supply after temperature controller (4) is in series, the thermal insulator (5) that aluminosilicate material is arranged between housing (1) and heat storage (2), thermal insulator (5) is wrapped in heat storage (2) and heat storage is fixed on housing (1) bosom position, heat storage (2) is by carborundum, zircon sand and clay are in the synthetic far-infrared material manufacturing of the ratio of 5:2:3, and apply a far infrared coating (6) at the outer surface of heat storage (2), make heat storage produce far-infrared thermal radiation.Heat storage (2) is gone up and is fixed a micarex (13) by a screw (14), intrinsic temperature controller (4) on the micarex, electric heating body (3) is wrapped in the heat storage for metal material, as shown in Figure 2 electric heating body (3) and the temperature controller (4) that adopts the closed normally-closed contact of small-sized pottery are in series in main circuit, and be fastened on socket (10) on the housing (1), connect secondary flexible circuit conductor (11), plug (12) and directly insert mains-supplied.A resistor in parallel (7) and indicator lamp (8) carry out state and show between electric heating body in circuit (3) and the temperature controller (4), the temperature controller of closed normally-closed contact is avoided the intrusion of thermal insulator and foreign matter, improve the sensitivity of element, guarantee reliability of structure, and control the accuracy of the utility model actual temperature by the closure of contact.

Behind power connection, electric heating body (3) begins heating, make heat storage (2) temperature rising store heat, indicator lamp is bright during duty, when reaching uniform temperature, the normally-closed contact of temperature controller disconnects indicator lamp and goes out, and can pull up attaching plug and warm oneself, at this moment heat constantly distributes from heat storage, is transmitted on the housing (1) by thermal insulator (5) and heats.At this moment owing to heat storage employing far-infrared material, and in its surface-coated the far infrared coating is arranged, can produce the far-infrared thermal radiation effect, temperature retention time reaches 2-3 hour.

Embodiment 2 is as shown in Figure 3: the both ends of the surface middle part is provided with two magnetic metal pieces (9) in housing (1), not only warms oneself but also the effect of body-building but make the utlity model has.The material manufacturing that heat storage (2) also can adopt rare earth element, zircon sand and clay to form in the ratio of 5:2:3.

The utility model has the advantage of: simple in structure, low in energy consumption, be easy to carry owing to produce far-infrared thermal radiation, behind the deenergization continuously temperature retention time reach 2-3 hour, and temperature stabilization, reliably practical.
