Abstract

The utility model provides a combined toilet seat for a water flushing toilet, which can carry out preheating and can temperature control. The utility model is realized through increasing an electric heating element and a simple temperature control device which is independent from the combined toilet seat for a water flushing toilet on the basis of an existing combined seat for a water flushing toilet. The utility model has the advantages of simple structure, convenient operation and less power consumption. When the utility model is used by people in winter, the temperature of the combined seat can be constant in proximity to the temperature of surface of human body, so the people can feel comfortable and safe.

Description

Pre-heating water flushing toilet seat

The utility model relates to a kind of family expenses toilet assembled base that can give heat.

Toilet supply in the market or that family uses, no matter be the formula of lid arranged or non-cover type, when using in the winter time, people feel ice-cold sharp usually, very uncomfortable, for this reason, there is the people on the seat ring of toilet assembled base, to add a cloth cover, to improve the temperature of seat ring, though adopt this way simple and easy, have the defective of owing health and bothering.

The purpose of this utility model provides a kind of toilet assembled base that can give heat and have simple and easy temperature control equipment, the giving hot temperature and can make things convenient for, be adjusted to rapidly near human surface temperature and can constant temperature of its seat ring was so that people had not only felt comfortably cool but also had been perfectly safe when using in the winter time was reliable.

The utility model is to realize like this, on the basis of existing toilet assembled base, set up a heating and easy temperature control equipment, its scheme is as follows: the toilet assembled base comprises flap and seat ring, position setting-in one corresponding to seat ring in flap encloses heating, and with a metal heat-conducting circle heating is enclosed in the flap, heating then links to each other with AC power through step-down by a relay.Give when hot flap is covered ring here, behind power connection, heating heating in the flap, the metal heat-conducting circle is heated up, the heat of metal heat-conducting circle is transmitted on the seat ring uniformly, on the metal heat-conducting circle, fix a temperature-sensing element, when the temperature of metal heat-conducting circle rises to when giving the temperature value of establishing, place the temperature control equipment in the temperature control capsule that the normally closed contact of relay is thrown off by one, automatically cut off the electricity supply, when the temperature of metal heat-conducting circle is lower than predetermined value, can connects power supply automatically again and heat.Temperature control capsule be one with the discrete parts of toilet assembled base, the required power supply of heating is delivered on the flap by temperature control capsule, the temperature-sensitive signal of temperature-sensing element is delivered to temperature from flap and is controlled in the capsule.

The utility model because only on existing toilet assembled base, increase the heating of a low-voltage and one with the discrete simple and easy temperature control equipment of toilet assembled base, thereby when people when using winter, the temperature of seat ring can be constant in the temperature value near human body surface in the toilet assembled base, and have simple in structure, easy to use, safe and characteristics that power consumption is little.

Below in conjunction with accompanying drawing the utility model is specifically described:

The utility model has 4 accompanying drawings

Fig. 4 temperature-control circuit figure

Give hot type toilet assembled base mainly by flap 1, seat ring, heating 5, temperature control equipment is formed, the structure of flap such as Fig. 1, shown in Figure 2, position corresponding to seat ring in flap 1 has a circle groove, its cross section is a stepped ramp type, 5 is the heating RL5 that places below groove, adopt nickel-chromium resistance wire, the metal metal heat-conducting circle 6 of usefulness, as aluminium, seal the opening of groove, when flap 1 was covered seat ring, metal heat-conducting circle 6 just in time coincide with seat ring, nichrome wire in the flap 1 links by the normally closed contact and the power supply of a relay J, form a heating circuit, for safety, heating RL5 power source voltage is reduced to 40VAC through transformer, the resistance of nickel-chromium resistance wire is 320 Ω, the material selection timber or the plastics of flap 1.Temperature control equipment mainly is made up of temperature-sensing element 2, signal comparator circuit, control circuit, power circuit, as shown in Figure 4, temperature-sensing element 2 is a thermistor Rt who is fixed on the metal heat-conducting circle 6, and the input of comparator A is provided with potentiometer W in the signal comparator circuit ₁And thermistor Rt, control circuit is provided with transistor BG ₁And relay J, transistor BG ₁Base stage through resistance R ₆Link to each other with the output of comparator A, its colelctor electrode links to each other with relay J, after the flap 1 of toilet assembled base covered, and connects power supply, flap 1 began to heat up, simultaneously heat is conducted to seat ring, when the temperature of seat ring was relatively hanged down, the resistance of thermistor Rt was higher, and the voltage of comparator A in-phase input end is lower than inverting input, comparator A is output as low level, transistor BG ₁Not conducting, relay J is failure to actuate, and heating circuit continues heating, and along with the rising of metal heat-conducting circle temperature in the flap, the resistance of thermistor Rt progressively diminishes, and comparator A in-phase input end voltage constantly rises, by giving the good potentiometer W of levelling earlier ₁Resistance, when making thermistor Rt sense near the human surface temperature, the voltage of in-phase input end is greater than the voltage of inverting input, comparator A is output as high level, transistor BG ₁Conducting, the normally-closed contact of relay J is thrown off, and heating circuit stops heating, thereby the temperature of seat ring can be constant give fixed temperature value, and fluctuation is not more than 3 ℃ up and down, and the temperature control equipment supply voltage is 12VDC, by secondary transformer tap 11VAC, after full-wave rectification, obtain.Temperature-control circuit places in the capsule, the profile of this temperature control capsule as shown in Figure 3,7 is fixing hole, temperature can be controlled capsule and be fixed near the toilet the wall, 8 is indicator lamp, 9 is potentiometer W ₁Adjusting knob is used for setting the hot temperature of giving of seat ring, and 10 is power switch, and 11 is the plug that links with heating RL5, and 12 is the plug that links with thermistor Rt.In the both sides of flap 1 jack 3 and jack 4 are housed respectively, obtain after the required power supply of heating RL5 links by plug 11 and jack 3, the temperature-sensitive signal of thermistor Rt is delivered to temperature control capsule after linking by plug 12 and jack 4.
