Abstract

The utility model discloses a constant temp. ring cushion for a closet seat which is composed of a heating ring (1) and a thermostat (2), wherein, the heating ring is composed of an electrical lead (3), an insulating sealing ring (4) and a heating wire (5); the thermostat is mainly composed of a bidirectional thyristor, a bidirectional diode, a thermally-sensitive member and an adjustable resistance. The utility model is fixed to the reverse side of the cover of a closet seat, which does without the physical contact, and the utility model is mainly used for putting contact type heat conduction and heat radiation to the ring cushion of an original closet seat. The thermostat can automatically hold a selected temperature, so the utility model has the advantages of convenient and safe utilization and warmness and comfort.

Description

Constant temp. ring cushion for closet seat

The utility model is employed a kind of warming constant temperature seat ring on the toilet seat of lavatory.

Toilet seat is clean, sanitary, convenient, comfortable.Can work as temperature cool slightly (about below 20 ℃) and a bit relax and uncomfortable, warm skin and ice-cold seat ring are in contact with one another, and the sense of the sort of discomfort makes the toilet seat blemish in an otherwise perfect thing that seems, though have heating installation (about 16 ℃ of room temperatures) can use still ice-cold discomfort to the winter.At present disposable seat ring paper washer is adopted in some hotel, still some cold, if move when just placing not or sitting also can make a stupid mistake next; Some family adopts textile system cover for seat, and is this extremely unhygienic, can become the just hiding-place of middle germ.

The purpose of this utility model is the problem that overcomes above-mentioned existence, designs the reverse side that a kind of electricity heating circle that is made of insulating materials and heating wire makes it to be fixed on pan closet lid; Simultaneously on the electrical lead of electricity heating circle, add a temperature controller, make it under the situation of spread of voltage, to keep constant temperature.

The utility model is to realize with following technical measures: it connects the insulation circle (1) of heating by power line through temperature controller (2) and is constituted, the circle (1) of wherein heating is installed in the back side of toilet lid, and the described circle (1) of heating is to be made of in the O-ring seal of insulation the casting of some circle heating wire folders.Temperature controller (2) is by A, the K utmost point of power firestreak through K switch series connection bidirectional triode thyristor SCR, and being heated by the K utmost point series connection insulation of SCR connects with zero-power line behind the heating wire RL in the circle again; Two ends after resistance R, potentiometer W, the capacitor C series connection are connected in parallel on A, the K utmost point of SCR; The G utmost point of diac D one end SCR, an end is serially connected with the end of C, and the two ends of capacitor C also meet thermistor RMF and constitute.

The utility model structure and circuit thereof are simple and practical, owing to adopt temperature controller through experimental result: 30 ℃～40 ℃ of temperature ranges of choice, voltage 230V, temperature transfers to 37 ℃; Temperature departure constant temperature when voltage is reduced to 150V is reduced to 34 ℃; When voltage is stablized, 15 ℃ of variation of ambient temperature, constant temperature value constant substantially (variation) less than 0.5 degree centigrade.

This constant temperature seat ring is safe and reliable: because of its electric thermal power little (about 15W), and temperature low (below 40 ℃), and electric heating coil need not and Body contact.

Snugness, easy to use: serviceability temperature is selected arbitrarily between 30 ℃～40 ℃, and electronic temperature control can keep selected temperature automatically, when enabling once more, only needs the pressing switch to get final product, and temperature still remains on set point value, need not to transfer again.

Power consumption is little: 12 ℃～14 ℃ of room temperatures, and under 36 ℃ of conditions of temperature control, day power consumption 0.34 degree, month power consumption 10.2 degree, if close night, month power consumption 6.8 degree.

Clean, sanitary: owing to adopted sealed insulation rubber heating collar, so whole toilet seat can be sterilized, flushing, wiping (it is better to close swap switch certainly), the heating wire that is sealed in the rubber ring is difficult for oxidation, and rubber needs more than 10 years, so long service life at aged deterioration under 40 conditions.

At the fixing a slice electric heating cushion rubber of toilet lid inner surface, do not influence outward appearance U.S., otherwise reduced or remitted the rigid collision between former lid and the ring in addition.

Fig. 2 a is a constant temperature seat ring front view.

B is that a constant temperature seat ring left side is looked and cutd open figure.

C is that a constant temperature seat ring left side is looked and cutd open that figure is local to be amplified.

Fig. 3 is the temperature controller circuit theory diagrams.

Be further described in conjunction with Fig. 1～3 pair use of the present utility model and principle thereof.

Shown in Figure 1, manufacture a sealing, the electricity heating circle of insulation is fixed on the reverse side of toilet lid, electronic temperature control device 2 one termination 220V power supplys, an end connects the electrical lead 3 on the heating collar, and its maintenance constant temperature of switching on continuously is so that all can use at any time.

As shown in Figure 2, sealed insulation electricity heating circle is that heating wire is injection-moulded in the sheet rubber ring, electrical lead glue envelope, and cushion rubber thickness is 2.5～3.0mm, and heating wire is positioned at the middle level, and this thickness satisfies electric insulation and heat conduction requirement.Shown in Figure 1, the electricity heating cushion rubber of manufacturing shaping is fixed on the reverse side of toilet lid, during non-at ordinary times use, cap covers, the lid cushion rubber of heating of dress down directly contact with the seat ring upper surface, and energising constant temperature cushion rubber is just passed to heat seat ring (contact conduction and radiation), uncap when seat ring has just possessed certain temperature (adjustable between 30 ℃～40 ℃) use, the heating cushion rubber is together raised with lid, and human body need not come in contact with the circle of heating, and uses snugness, safe and reliable.

The operation principle of temperature controller is like this: as shown in Figure 3: after the K switch closure, alternating current forms alternating voltage at controllable silicon A, K two ends.When alternating current during at positive half cycle, electric current forms pulse voltage through R, W at the RMF two ends, and to the capacitor C charging, when charging voltage arrived the conducting voltage of bidirectional trigger diode D, capacitor C is discharge rapidly between silicon controlled K, G, makes the controllable silicon conducting.When alternating current when the zero point, controllable silicon is blocked automatically owing to adopt bidirectional triode thyristor and diac, alternating current when negative half period in like manner.After the controllable silicon conducting, the RL temperature raises, and the RMF temperature that is installed together with it is raise.The RMF resistance descends, and RMF two ends pulsating volage descends thereupon, has prolonged the charging rate of capacitor C, and thyristor operating angle reduces, the RL temperature reduces, and the RMF resistance is gone up, and accelerates the electric capacity charging, and thyristor operating angle increases, the RL temperature is gone up again, and so effect makes the RL temperature be in a kind of stable state.

If adjust the resistance of W, also can change the charging rate of capacitor C, the increase and decrease silicon controlled angle of flow under the compensating action of RMF, makes the temperature of RL remain on a new stable state, thereby realizes the regulating and controlling effect to the RL temperature.
