Fig. 2 is that the utility model removes the internal structure chart after panel.
Fig. 3 is the cross-sectional view in Fig. 1 along line A-A.
In figure:
Electric ceramic heaters furnace body 1, heat-generating disc 3, infrared sensing device 4, control circuit board 5, induction soft-touch control 21, leads to panel 2
Hole 22, fixing seat 41, infrared sensor 42, indicator light 43, infrared detection signal 420.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, the electric ceramic heaters that a kind of automatic sensing is shut down, including electric ceramic heaters furnace body 1, it is mounted on electric ceramic heaters
Panel 2 on furnace body 1 and the heat-generating disc 3 and control circuit board 5 being arranged in furnace body 1, the heat-generating disc 3 and control circuit board 5
It is electrically connected, panel 2 is micro-crystal plate, and the upper opening of heat-generating disc 3 is directly connected with the bottom of panel 2, so that heat-generating disc 3 is issued
Heat farthest pass through panel 2 and be transmitted on cookware.And heat-generating disc 3 is made of nichrome heat piece and adiabatic disks, is utilized
Heating effect of current converts electrical energy into thermal energy, and it has the characteristics that not choose that pot, radiationless, temperature is high, adapts to distinct group
Body uses.In addition, several induction soft-touch controls 21 are additionally provided on the panel 2, the induction soft-touch control 21 and control electricity
Road plate 5 is connected, and user only needs touch sensible soft-touch control 21 just and can control the switch of electric ceramic heaters or the size of firepower, compared to tradition
Key switch have the characteristics that beautiful, class is high.
As shown in figure 3, the infrared sensing device 4 for incuding cookware is additionally provided in the electric ceramic heaters furnace body 1, it is described infrared
Sensing device 4 includes fixing seat 41, infrared sensor 42 and indicator light 43, and specifically, indicator light is mounted on control circuit board 5
On, user can be allowed to observe the state of infrared sensor 42 at the first time.Infrared sensor 42 is then pacified by fixing seat 41
In electric ceramic heaters furnace body 1, directly it can dismantle and repair from fixing seat 41 after the damage of infrared sensor 42, use
Above-mentioned detachable connection type can it is more convenient, rapidly replace infrared sensor 42.And the infrared sensor
42 are electrically connected with control circuit board 5, and after electric ceramic heaters are powered, user passes infrared ray by touch sensible soft-touch control 21
Sensor 42 is opened, and electric ceramic heaters can enter working condition after infrared sensor 42 senses cookware.In order to pass infrared ray
For the 420 energy light-transmitting panel 2 of infrared detection signal that sensor 42 issues to sense cookware, the panel 2 is equipped with through-hole 22,
The infrared detection signal 420 that the infrared sensor 42 issues passes through the top that through-hole 22 is radiated at panel 2, it is preferable that
The distance of reaction H of the infrared sensor 42 is 10 centimetres, and certainly, the distance of reaction of infrared sensor 42 also can be adjusted to
Other distances, such as be set as 8-15 centimetres it is also possible, and can also be by replacing different infrared sensor 42
Obtain different distance of reaction.But the distance of reaction of infrared sensor 42 should not be too large, also unsuitable too small, it is excessive be easy by
The interference of other objects, causes electric ceramic heaters abnormally to open；Too small, then induction is less than cookware, and slightly separate may just lead
Electric ceramic heaters are caused to close.Since present electric ceramic heaters thickness is generally at 7-9 centimetres or so, the induction of infrared sensor 42 away from
From generally having more the 1-2 centimetres of effect that can reach normal induction than the thickness of electric ceramic heaters.In addition, through-hole 22 is equipped with for red
The glass or plastic cover plate that outside line detection signal 420 passes through, cover board can prevent external water from entering electric ceramic heaters by through-hole 22
It is internal.
The working principle of the utility model are as follows: when cookware is placed on panel 1, infrared sensor 42 is issued infrared
Line detection signal 420 passes through through-hole 22 and is radiated on cookware, since the presence of cookware hides infrared detection signal 420
Gear, infrared sensor 42 is in normally off at this time, and indicator light 43 is shown in green, and infrared sensor 42 is by normally off
Signal is transferred in control circuit board 5, and control circuit board 5 just connects the power supply of heat-generating disc 3, and user passes through induction soft-touch control 21
Electric ceramic heaters can be opened；On the contrary, when cookware from panel 2 by of short duration detach after, infrared sensor 42 issue infrared ray
Detection signal 420 is not blocked, and infrared sensor 42 is in normally open at this time, and indicator light 43 is shown in red, infrared ray
Normally open signal is transferred in control circuit board 5 by sensor 42, and control circuit board 5 disconnects the power supply of heat-generating disc 3 at once, is made
It obtains cookware and is in the state stopped by electric ceramic heaters in the of short duration this period detached, the no-load operation for avoiding electric ceramic heaters is brought
Power consumption energy consumption, one side user do not need every time it is of short duration will voluntarily close electric ceramic heaters when detaching cookware, still further aspect makes
It obtains electric ceramic heaters and has reached energy-efficient purpose, meet the pertinent regulations of professional standard and country.Further, since infrared sensor 42
High sensitivity, reaction speed is fast, guarantees opening or closing at any time for electric ceramic heaters, user-friendly.
As an improvement, fan (not shown) is additionally provided in the electric ceramic heaters furnace body 1, for electric ceramic heaters furnace body 1
Cooling and heat dissipation.
In conclusion the utility model more intelligence and safety, also solve while increasing convenience for users
The security risk of each family, is truly realized energy conservation and environmental protection.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
