Description

Switch

Technical field

The utility model relates to a kind of switch.

Background technology

Along with the raising of people's living standard, have a bath at home the most universal.In order to ensure the temperature in bathroom, often with bath Despot heats for bathroom.Super bath is typically to be made up of multiple powerful infrared bulbs and a housing, and each infrared bulb is usually 500W, a usual super bath uses 4 infrared bulbs, therefore a super bath 2000W altogether.In order to control temperature, it will usually logical Cross multiple switch to be adjusted, i.e. one one or two infrared bulb of switch control rule, control, with this, the quantity every time turned on light, Although this method is simple, but need when using artificial to go regulation, be inconvenient for.And some super baths are also adopted by single-chip microcomputer etc. and enter Row automatic temperature measurement, although temperature control is more accurate, but its structure is complicated, cost is high, fragile.

Utility model content

For reaching above-mentioned purpose, the purpose of this utility model is to provide a kind of simple in construction, switch easy to use.

For reaching above-mentioned purpose, switch of the present utility model, including panel and the switch module being arranged on panel, described At least provided with a temperature measurement module on panel, wherein, described temperature measurement module is made up of normally closed thermoswitch and diode, institute The thermoswitch stated and diodes in parallel connect, and the described switch module on panel is connected with described temperature measurement module.

Wherein, described panel is provided with thermometric window；Described temperature measurement module includes: the housing mutually fastened with panel； Described housing and panel form a hollow bulb；In described hollow bulb, corresponding thermometric window is provided with a thermal conductive metal plate or heat conduction Metal-back, the nearly thermal conductive metal plate of described thermoswitch or heat-conducting metal shell are arranged.

Wherein, described thermal conductive metal plate or surface, heat-conducting metal shell nearly thermometric window side are provided with multiple point-like or strip projected parts.

Wherein, between described switch module and described temperature measurement module, a PTC thermistor also it is in series with.

Wherein, it is provided with sealing ring between described thermal conductive metal plate or heat-conducting metal shell and thermometric window.

The utility model of said structure, is made up of normally closed thermoswitch and diode, when indoor temperature reaches predetermined temperature, Normally closed thermoswitch disconnects, and power supply powers to the load by after diode halfwave rectifier, thus reduces the voltage of supply load, Make load can not be fully loaded with work, to reduce indoor temperature.And when temperature is less than predetermined temperature, normally closed thermoswitch then turns on, Power supply is powered to the load by thermoswitch so that the fully loaded work of load, to improve indoor temperature.In summary, this practicality is new The switch of type has simple in construction, easy to use, the advantage of low cost.

Accompanying drawing explanation

Fig. 1 is the structural representation of embodiment of the present utility model.

Fig. 2 is that the A-A of embodiment illustrated in fig. 1 is to cross-sectional schematic.

Fig. 3 is the principle schematic of the utility model embodiment.

Detailed description of the invention

Below in conjunction with the accompanying drawings the utility model is further described.

As depicted in figs. 1 and 2, switch of the present utility model, including panel 1 and the switch module 2 that is arranged on panel, At least provided with a temperature measurement module 3 on described panel, wherein, described temperature measurement module is by normally closed thermoswitch 5 and two poles Pipe 6 forms, and described thermoswitch 5 and diode 6 are connected in parallel, the described switch module on panel and described thermometric Block coupled in series.

Fig. 3 show the utility model switch operation principle:

After switch module K2 closes, owing to thermoswitch K1 is closed type, power supply turns on, and therefore diode is shorted, electricity Source is powered to the load by thermoswitch so that the fully loaded work of load, to improve indoor temperature.When temperature reaches predetermined temperature, Normally closed thermoswitch disconnects, and power supply powers to the load by after diode halfwave rectifier, thus reduces the voltage of supply load, Make load can not be fully loaded with work, to reduce indoor temperature.In summary, switch of the present utility model utilizes a thermoswitch It is achieved that the thermometric in bathroom and temperature control, there is simple in construction, easy to use, the advantage of low cost.

Improve further as the utility model, as it is shown on figure 3, also connect between switch module and described temperature measurement module There is PTC thermistor Rt, after increasing this thermistor, when after power on, due to main branch PTC thermistor Rt Existing, its resistance is more and more less along with the prolongation of conduction time so that the electric current of main load (infrared bulb) be slowly increased, So that load (infrared bulb) gradually increases to full load condition, decrease load (infrared bulb) electric current when moment is energized Impact to filament, extends the life-span of load (infrared bulb).

Fig. 2 show an embodiment of the utility model switch, as in figure 2 it is shown, be provided with thermometric window 11 on panel 1； Described temperature measurement module includes: the housing 31 mutually fastened with panel 1；Described housing and panel form a hollow bulb；Institute In the hollow bulb stated, corresponding thermometric window is provided with a thermal conductive metal plate or heat-conducting metal shell 32, described thermoswitch 5 nearly heat conduction gold Belong to sheet/heat-conducting metal shell to arrange.

Improve further as the utility model, be provided with at thermal conductive metal plate or surface, heat-conducting metal shell 32 nearly thermometric window side Multiple point-like or strip projected parts, to increase the sensitiveness of its temperature sensor.

Improve further as the utility model, between thermal conductive metal plate or heat-conducting metal shell and thermometric window, be provided with sealing ring. To prevent water or water smoke from entering in temperature measurement module.

Above, preferred embodiment the most of the present utility model, but protection domain of the present utility model is not limited thereto, and any ripe Know those skilled in the art in the technical scope that the utility model discloses, the change that can readily occur in or replacement, all answer Contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be defined with claim Protection domain is as the criterion.
