Description
[technical field]
The present invention relates to a kind of Novel gas stove temperature sensor.
[background technology]
At present, control in field of temperature measurement at gas-cooker intelligent cooking, contact type temperature sensor is mounted in the middle of burner, and by the temperature of sensor contacts cooker indirect inspection food, existing contact type temperature sensor exists following problem when detected temperatures:
1, Fire Radiation, because temperature sensor is mounted in the middle of burner, flame high temperature can be radiated sensor, makes sensor self-temperature just higher than the temperature of testee, so cause temperature measurement error;
2, heat transfer, because the temperature-sensitive head of sensor must depend on some structural members to support, structural member must be connected with temperature-sensitive head, suppose that the temperature of structural member is higher than testee, so the heat of structural member can be transmitted to temperature-sensitive head, thus causes measuring tempeature higher than the true temperature of testee; Same reason, suppose that structural member temperature is lower than testee, so a part of heat of temperature-sensitive head can be taken away by structural member, so measuring tempeature can be caused lower than the true temperature of testee.
Therefore, be necessary to solve as above problem.
[summary of the invention]
Instant invention overcomes the deficiency of above-mentioned technology, provide a kind of Novel gas stove temperature sensor, its structure is simple and easy to realize, and antijamming capability is good.
For achieving the above object, present invention employs following technical proposal:
A kind of Novel gas stove temperature sensor, include the guide cylinder 1 for being fixed on gas-cooker, described guide cylinder 1 upper end is arranged with can the slide cartridge 2 that slides of relatively described guide cylinder 1, described slide cartridge 2 is provided with upper shed 21 and under shed 22, described guide cylinder 1 extend in described slide cartridge 2 from described under shed 22, described slide cartridge 2 fixes the back up pad 3 that shutoff has low thermal conductivity on the inwall of described upper shed 21, elastic component 4 is provided with between described back up pad 3 and described guide cylinder 1, described back up pad 3 is provided with vertical intercommunicating pore 31, described back up pad 3 is provided with and passes temperature and the heat-transfer disc 5 sealing described vertical intercommunicating pore 31 for contacting with cooker, described temperature sensor also includes the thermopair 6 extending in described guide cylinder 1 and be connected with described heat-transfer disc 5 lower surface in slide cartridge 2.
Described under shed 22 concaves, and described guide cylinder 1 upper end is provided with the limited step 11 for preventing described slide cartridge 2 from coming off from guide cylinder 1 upper end, and described elastic component 4 top is pressed between described limited step 11 upper surface and described back up pad 3 lower surface.
The thermode of described thermopair 6 is riveted on described heat-transfer disc 5.
Described guide cylinder 1 lower end outer wall is provided with the annular projection 12 for being connected on gas-cooker.
Described heat-transfer disc 5 upper surface is circular flat.
Described elastic component 4 is spring.
Described back up pad 3 adopts microcrystal glass material to make, and described heat-transfer disc 5 is bonded in described back up pad 3 by high-temp glue.
Compared with prior art, the invention has the beneficial effects as follows:
1, antijamming capability is good, during use, outside cooker top pressure heat-transfer disc, slide cartridge can reduce the direct heat radiation of external flame to heat-transfer disc, the back up pad of low thermal conductivity can reduce the heat transfer of slide cartridge to heat-transfer disc, so, reduce the impact of environment on heat-transfer disc, and, heat-transfer disc seals the vertical intercommunicating pore in back up pad, thermopair is not affected by hot outside, and thermopair only carrys out induction cookware temperature by heat-transfer disc, and temperature detection is more accurate.
2, the under shed on slide cartridge concaves, and described guide cylinder upper end is provided with the limited step coordinated with described under shed, can prevent slide cartridge from coming off from guide cylinder upper end.
[accompanying drawing explanation]
Fig. 1 is cut-open view of the present invention.
[embodiment]
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As shown in Figure 1, a kind of Novel gas stove temperature sensor, include the guide cylinder 1 for being fixed on gas-cooker, described guide cylinder 1 upper end is arranged with can the slide cartridge 2 that slides of relatively described guide cylinder 1, described slide cartridge 2 is provided with upper shed 21 and under shed 22, described guide cylinder 1 extend in described slide cartridge 2 from described under shed 22, described slide cartridge 2 fixes the back up pad 3 that shutoff has low thermal conductivity on the inwall of described upper shed 21, elastic component 4 is provided with between described back up pad 3 and described guide cylinder 1, described back up pad 3 is provided with vertical intercommunicating pore 31, described back up pad 3 is provided with and passes temperature and the heat-transfer disc 5 sealing described vertical intercommunicating pore 31 for contacting with cooker, described temperature sensor also includes the thermopair 6 extending in described guide cylinder 1 and be connected with described heat-transfer disc 5 lower surface in slide cartridge 2.
Described under shed 22 concaves, and described guide cylinder 1 upper end is provided with the limited step 11 for preventing described slide cartridge 2 from coming off from guide cylinder 1 upper end, and described elastic component 4 top is pressed between described limited step 11 upper surface and described back up pad 3 lower surface.
