Abstract

The utility model relates to an automatic regulating constant temperature bed, comprising a mattress and a heating chamber. The bed can be provided with a bed head or none. The heating chamber can be arranged in the bed body or in the mattress, composed of two electric control lines which can automatically keep constant temperature or adjustable three-step temperature. Compared with the prior art, the utility model has the advantages of low cost, wide temperature-controlling scope, wide range of application, novel and beautiful style.

Description

Automatic regulating constant temp. bed

A kind of constant temperature temperature adjustment bed is applicable to the infrared ray automatic constant-temperature temperature adjustment bed of daily life and health care.

The inventor has designed multiple constant temperature bed, and has declared patent, and wherein 87203445.3 " four seasons constant temperature beds " are with far infrared electronic component heating heating, lower the temperature with the refrigeration of electronics heap.Through the practice test, this constant temperature bed is also unsatisfactory, and is unreasonable as structure, and the temperature control scope is also narrower, and the scope of application is less, use the refrigeration heap also to have some disadvantages, and the temperature control instrument cost is higher.

The purpose of this utility model provides a kind of applied widely, constant temperature, temperature adjustment bed that structure is more reasonable, cheap.

The purpose of this utility model is achieved in that internal crucible comprises mattress and heating clamber, the head of a bed can be arranged or do not have the head of a bed, and heating clamber can be located at can not had lathe bed in the lathe bed yet and heating clamber is located in the mattress.Circuit comprises automatic constant-temperature control circuit or many grades of thermoregulation circuits, and it causes warm element surface can be coated with infra-red paint, improves heating effect, and health care is arranged, and can certainly not be coated with infra-red paint, is the common heating element.Control circuit comprises the power circuit that is made of voltage stabilizing, rectifying device, by three triodes and the resistance, the potentiometer that are complementary and be subjected to the relay of triode control, the on-off circuit that thermistor is formed, also comprise the heating and the signal lamp part that controlled by relay contact.Thermoregulation circuit is a third gear switch, and one group of heating of polyphone is arranged, and stepping is connected, and corresponding signal lamp is arranged.

But the utility model is divided into from temperature control or temperature adjustment, several models such as the head of a bed, the no head of a bed, lathe bed heating clamber and cushion heating clamber is arranged, the scope of application increases, being fit to each age personnel respectively uses, also can be suitable for ethnic group's custom, and the temperature control circuit is simple and practical, does not use the digital temperature control instrument of high price, piles without refrigeration, reduced cost, and it is attractive in appearance to have a fashion style.

Details of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is the utility model example 1 structural representation.

Fig. 2 is the utility model example 2 structural representations.

Fig. 3 is the utility model example 3 structural representations.

Fig. 4 is an automatic constant-temperature control circuit schematic diagram.

Fig. 5 is automatic constant-temperature control panel face figure

Fig. 6 is a temperature adjustment control circuit schematic diagram.

Fig. 7 is that temperature adjustment control panel face figure Fig. 8 is a heating clamber schematic diagram in mattress.

With reference to the accompanying drawings 1, present embodiment is made up of the head of a bed 1, lathe bed 2, mattress 3.Be provided with appliance controling plate 4 above the head of a bed 1, there is heating clamber 5 at lathe bed 2 middle parts, and there is ground light 6 lathe bed 2 sides.Wherein in the heating clamber heating element heater is housed, it is exothermal infrared element of sheet or common heating sheet, and the chamber cover has safety protective net, four castors is arranged below the lathe bed 2.

With reference to the accompanying drawings 2, present embodiment is made up of lathe bed 8, cushion 7, lathe bed 8 no castors; be to be suitable for the minority area to use the platform-type bed; its lathe bed 8 middle parts have heating clamber 9 equally, and interior dress heating element heater also is stamped safety protective net, and appliance controling plate face 10 is installed in lathe bed 8 sides.

With reference to the accompanying

drawings

3,8, present embodiment is a kind ofly can be placed on any type of lathe bed or ground two-sided cushion, have by geometrical clamp 14 fixing in the spring mattress saddle 11, the heating clamber 15 that constitutes by spring hose and ceramic insulating tube, therefrom pass heating conductor 13, temperature adjustment or temperature control switch 12 are contained on the power line.

With reference to the accompanying drawings 4 and 5, the automatic constant-temperature temperature-adjusting circuit comprises the power circuit of being made up of transformer BK, fuse RD, silicon bridge QL and capacitor C 1 and voltage-stabiliser tube WY; By triode BG ₁, BG ₂, BG ₃And be connected to the resistance R that is complementary of base stage ₂, R ₃, R ₄And voltage regulation resistance R ₅, R ₆, also have thermistor Rt and W ₂, be connected to BG ₃The on-off circuit formed of relay J, parallel diode D; Also comprise relay normally open contact JK ₁Normally-closed contact JK ₂The heating YHW and the signal lamp XD of control ₁, XD ₂Operation principle is: after K switch is connected, reduce to trouble free service voltage by fuse RD by transformer BK, through silicon bridge QL rectification, C ₁, C ₂Filtering, and current-limiting resistance R1 offer the WY voltage stabilizing, thereby a stable operating voltage that not influenced by power-supply fluctuation are provided.With W ₂The potentiometer definite value is got 30 ℃ (or 32 ℃, 34 ℃, 36 ℃, 38 ℃, 40 ℃) at a desired value, establishes at that time that room temperature is 15 ℃, after the energising, and BG ₁The triode conducting is passed through by BG1 through whole electric currents of R3, then BG ₂Not conducting, BG ₃Conducting makes the J adhesive, JK ₁Connect XD ₁Bright, heating element heater YHW connects heating simultaneously, when temperature is elevated to W ₂During predetermined value, Rt resistance drops to and makes BG ₁End, impel BG ₂Conducting, BG ₃End, J discharges as a result, JK ₁Disconnect XD ₁Go out XD ₂Bright, YHW stops heating.Temperature descends, and when dropping to a definite value, during as 28 ℃, said process begins again, goes round and begins again, and realizes temperature automatically controlled.

With reference to the accompanying drawings 6,7, battery main switch K ₁, temperature regulating switch has high, medium and low third gear, presses wherein one grade, and corresponding circuit is connected, and also has corresponding resistance R ₁, R ₂With signal lamp XD ₁, XD ₂Heating element heater YHW is one group of polyphone, can connect respectively by high, medium and low, needs temperature with adjusting, as presses K ₂Low grade, then heating is connected corresponding resistance R from 1 ₁Energising, XD ₁Bright; As press K ₂Middle-grade, then heating is connected corresponding resistance R from 2 ₂Energising, XD ₂Bright; As press K ₂Top grade, then heating is connected corresponding resistance R from 3 ₁, R ₂All lead to, two signal lamps are bright entirely.

More than two kinds of circuit and control panel can select arbitrarily, being complementary with aforementioned three kinds of examples constitutes automatic constant-temperature bed or temperature adjustment bed.
