Abstract
The utility model discloses a kind of gas-cooker of accurate display firepower size, comprise: burner, the valve be connected with burner, it is characterized in that, valve is provided with mass-air-flow sensor, described mass-air-flow sensor comprises heating element and temperature sensing device, and the signal that described temperature sensing device exports is shown by display after master controller conversion.Compared with prior art, the utility model adopts heating element and temperature sensing device to replace mechanical quantity converted measurement method of the prior art, has and measures accurate feature, accurately can reflect the process that large and small fire is changed.
Description
Technical field
The utility model relates to gas kitchen ranges technical field, especially relates to a kind of gas-cooker that accurately can show firepower size.
Background technology
Most gas-cooker all regulates firepower size by knob on the market, and the size of firepower is then indicated by the firepower on panel and embodies.But this firepower indicates and inaccuracy, when when carrying out Baoshang, boiling etc. and needing the operation accurately controlling firepower, user often needs to bend over to see fire, extremely bothers.
For this reason, people in industry, is had to propose a kind of firepower displaying device of household gas utensils, if one section of notification number is for as described in the Chinese patent of CN203928030U, it comprises: face glass, gas valve, signal generation apparatus and display unit, signal generation apparatus coordinates with gas valve.Like this, when rotating gas valve valve rod, signal generation apparatus rotates with valve rod, then the size of the firepower of display unit display burner.But because the spool of gas valve and valve rod exist gap, valve body exists return difference all the time, this device fails accurately to show the size of firepower, the process of especially large and small fire conversion.
Summary of the invention
For the defect existed in prior art, the purpose of this utility model is to provide that a kind of structure is simple, the more accurate gas-cooker of firepower display.
For reaching above object, the utility model adopts following technical scheme.
A kind of gas-cooker of accurate display firepower size, comprise: burner, the valve be connected with burner, it is characterized in that, valve is provided with mass-air-flow sensor, described mass-air-flow sensor comprises heating element and temperature sensing device, and the signal that described temperature sensing device exports is shown by display after master controller conversion.
Further illustrating as such scheme, is provided with signal amplification circuit between master controller and temperature sensor, improves certainty of measurement further.
Further illustrating as such scheme, described heating element is at least one, and described temperature sensor is at least two, and temperature sensing device is distributed in the both sides of heating element.
Further illustrating as such scheme, described heating element is electrical heating wire.
Further illustrating as such scheme, described temperature sensing device is thermistor.
Compared with prior art, the utility model has following beneficial effect:
One, adopt heating element and temperature sensing device to replace mechanical quantity converted measurement method of the prior art, have and measure accurate feature, accurately can reflect the process that large and small fire is changed.
Two, because temperature sensing device is distributed in the both sides of heating element, the electricity difference that measuring-signal is exported by two temperature sensing devices characterizes, and effectively reduces measure error.

Detailed description of the invention
For setting forth essence of the present utility model further, by reference to the accompanying drawings detailed description of the invention of the present utility model is described as follows.
As shown in Figure 1, a kind of gas-cooker of accurate display firepower size, comprising: burner 1, valve 2, air inlet pipeline 3, mass-air-flow sensor 4, master controller 5 and display 6; Described valve 2 is connected on burner 1, and mass-air-flow sensor 4 is connected between valve 2 and air inlet pipeline 3, and master controller 5 is connected with mass-air-flow sensor 4, and display 6 is connected with master controller 5.
Wherein, described mass-air-flow sensor 4 comprises: heating element and temperature sensing device, and the signal that temperature sensing device exports is shown by display 6 after master controller 5 is changed, and then reaches the object of accurately display firepower size.
In the present embodiment, preferred heating element is an electrical heating wire, and preferable temperature sensor is two the series thermal-sensitive resistance being arranged on electrical heating wire both sides.When gas-flow is through mass-air-flow sensor, make the temperature of two series thermal-sensitive resistance different, the resistance variation with temperature of thermistor and changing, and then produce potential difference on two series thermal-sensitive resistance.The present embodiment utilizes this potential difference to characterize firepower size exactly.
Further, for improving the accuracy characterized, between master controller 5 and mass-air-flow sensor 4, signal amplification circuit is provided with.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, such as, carries out suitably adjustment etc. to the quantity of heating element, temperature sensing device and arrangement position.It should be noted that these improve and modify all to drop within claims of the present utility model.
