Description
Technical field
The present invention relates to arrangement of temperature sensor body, in more detail, be related to not directly with electric cooker
Interior pot is in contact the non-contact temperature sensor structure of the also electric cooker of measurable temperature.
Background technology
Generally, the cooking equipment such as electric cooker refers to the equipment for cooking food, according to for cooking
Mode of heating be divided into resistive heater heats mode and induction heating mode.Above-mentioned sensing heating side
Formula refers to such a way, i.e. if being supplied to the coil for the bottom for being configured at body in a winding manner
To high frequency electric, then the interior pot for being contained in the inner side of above-mentioned body is sensed by electromagnetic induction
Heat (Induction heating, IH).
Fig. 1 a are the structure chart for the structure for schematically illustrating conventional sensing heating electric pressure, Fig. 1 b
To show the contact type temperature sensor structure suitable for conventional sensing heating electric pressure
The sectional view of structure.
Such as Fig. 1 a, in conventional sensing heating electric pressure, by sensing heating to selectivity
The interior pot 4 that ground is contained in the inner side of coil base 8 of the configuration in body 2 is heated, therefore,
The internal pressure of pot 4 in by improving, is heated to complete to culinary art object in a short time
Cooking.Now, the top for containing the body 2 of above-mentioned interior pot 4 is covered by pot cover 1, if closing
Above-mentioned pot cover 1, then make the inner sealing of above-mentioned interior pot, so as to prevent from discharging heat, and then can maintain
High temperature, therefore can effectively cook, and during insulation, defined temperature can be maintained.
Therefore, being fixedly installed the top heat plate 5 of metal material in the bottom of above-mentioned pot cover, set
Optionally it is combined in the filling 7 of the peripheral part of above-mentioned top heat plate 5 with the upper end of interior pot 4,
So as to close the inside of interior pot 4.
Also, above-mentioned top heat plate 5 is formed with pressure valve and be connected with magnetic valve it is various
Pipeline, locking ring 3 is provided with the periphery of above-mentioned top heat plate 5, above-mentioned locking ring 3 is with rotation
Mode interact combination with forming flange in the upper end of above-mentioned interior pot 2, for performing lock function.
If moreover, the sensing in the outside for the coil base 8 for containing above-mentioned interior pot 4 to being wound in adds
Heat coil 9 applies the high frequency electric controlled by controller, then with by electromagnetic induction to being arranged at
The mode that the heated object of the metal material in the outside of above-mentioned interior pot 4 is heated is cooked.
On the other hand, generally, contact temperature is installed in conventional sensing heating electric pressure
Sensor structure.For example, such as Fig. 1 b, pacify in the inside of common sensing heating electric pressure
Equipped with actuating coil base 11, actuating coil is wound with the bottom surfaces of above-mentioned actuating coil base 11
12。

In the case that interior pot is positioned over above-mentioned actuating coil base 11, above-mentioned contact type temperature sensor structure
Body measurement temperature in the way of being in contact with above-mentioned interior pot.In this contact type temperature sensor structure
Body is provided with sensor body 13 by insertion actuating coil base 11 in the way of moving up and down,
Sensor 14 is installed on the inside of the upper end of sensor body 13.
Thus, if installing interior pot (not shown) in the inside of actuating coil base 11, interior pot is made
To bottom pinch sensors body 13, by making the sensor for being installed on sensor body 13 measure interior
The temperature of the bottom surfaces of pot carries out temperature survey.That is, by make sensor body 13 directly with it is interior
The bottom surfaces of pot (not shown) are in contact, and carry out internal pot and carry out temperature survey.
But, the problem of conventional contact type temperature sensor structure as described above has following.
First, contact type temperature sensor structure only could carry out temperature survey by contact,
Therefore, it is necessary first to consider the structure for effectively contacting, it is difficult to carry out precision thus to exist
The problem of temperature survey.
Second, sensor body 13 is the structure moved up and down in actuating coil base 11,
Therefore, had water leakage by the gap between sensor body 13 and actuating coil base 11
(for example, being had water leakage because pouring into cooking to actuating coil base with rice and water), so as to deposit
Electronic unit inside damage and the problem of cause the misoperation of electric cooker.
