<Characteristic configuration>
Next, a characteristic configuration of the gas stove A according to the embodiment of the present invention will be described.

  In the gas stove A according to one embodiment of the present invention, as shown in FIGS. 2 to 4, the temperature detection device 9 used in the standard burner (a stove burner) 1 a is provided with (a) one end side 11 a provided in the gas stove A. A fixed side support member 11 fixed to the fixed portion 61 and disposed such that the other end side 11b with respect to the one end side 11a extends in the vertical direction; and (b) a fixed side support member supported by the fixed side support member 11. The movable side support cylinder 12 is configured to be movable up and down with respect to 11, and (c) disposed at the upper end of the movable side support cylinder 12, and moves up and down following the vertical movement of the cooking container 40, thereby cooking. A contact body 13 configured to always contact the bottom surface of the container 40; and (d) a thermistor 14 disposed on the lower surface side of the contact body 13 in a manner to be thermally coupled to the contact body 13; It has. The thermistor 14 is connected to control means (not shown) via a thermistor lead wire 45.

A permanent magnet 15 having magnetic poles arranged in the vertical direction is disposed on the outer peripheral surface on the lower end side (position below the center) of the movable support cylinder 12. In this embodiment, the two permanent magnets 15 (15a, 15b) are arranged at positions facing each other with the movable support cylinder 12 therebetween so that the N pole faces downward and the S pole faces upward.
However, the number of permanent magnets 15 is not limited to two, but may be only one or three or more.

  Further, an electromagnet 16 that generates a repulsive force that urges the permanent magnet 15 upward by energization is disposed on the lower end side (a position below the center) of the fixed support member 11. In this embodiment, the two electromagnets 16 (16a, 16b) are disposed so as to be positioned below the two permanent magnets 15 (15a, 15b).

  Furthermore, the gas stove A according to this embodiment controls the current flowing through the electromagnets 16 (16a, 16b), and the temperature detecting device 9 is in the lowered state in which the upper surface of the contact body 13 is located below the upper end of the virtues 51. And a switching means for switching between the rising state of the temperature detection device 9 in which the movable support cylinder 12 is raised and the upper surface of the contact body 13 is located above the upper end of the virtues 51. That is, it is configured such that the above-described lowered state and raised state can be switched only by controlling the current supplied to the electromagnet 16 (16a, 16b).

  And in the gas stove A concerning this embodiment, the point fire extinguishing operation part 21a which instruct | indicates the point fire extinguishing to the standard burner (combustor) 1a, and the control means not shown in particular show the above-described lowered state and raised state. Switching means for switching is configured.

  Since the gas stove A of this embodiment is configured as described above, the temperature detection device 9 may become an obstacle when the cooking container 40 is moved on the virtues 51 in the lowered state of the temperature detection device 9. Absent.

  Further, when the cooking container 40 is placed on the virtues 51 in the rising state of the temperature detection device 9, the electromagnet 16 disposed on the stationary support member 11 and the movable support cylinder 12 are disposed. The moving support cylinder 12 is urged upward by the repulsive force with the permanent magnet 15, and the contact body 13 moves up and down following the upper and lower positions of the lower surface of the cooking container 40. Can be detected appropriately. That is, the repulsive force generated by the energization with respect to the permanent magnet 15 acts as an urging force for urging the moving side support cylinder 12 upward, so that the moving side support cylinder 12 is urged upward. An urging means such as a spring is not required, and the structure can be simplified.

  When the electromagnet 16 is not energized, the abutment body 13 and the movable support cylinder 12 are lowered by its own weight, and the upper end of the abutment body 13 is located below the upper end of the virtues 51. Therefore, when the cooking container 40 is moved on the virtues 51, the temperature detection device 9 does not get in the way.

  Further, since it is not necessary to connect a lead wire for supplying power to the moving side support cylinder 12 in order to move the moving side support cylinder 12 provided with the contact body 13 in the vertical direction, soup from the cooking container 40 or the like Thus, the conducting wire is not fixed to the gas stove body, and the smooth operation (vertical movement) of the moving side support cylinder 12 is not hindered.

  Here, the operation when the temperature detecting device 9 is switched between the lowered state and the raised state by the switching means will be described.

  When the electromagnet 16 is energized so that the N pole is generated in the upward direction and the S pole is generated in the downward direction, the moving support cylinder 12 is raised by the repulsive force of the permanent magnet 15 and the electromagnet 16 as shown in FIG. Thus, the temperature detecting device 9 is in a raised state in which the upper surface of the contact body 13 is located above the upper end of the virtues 51.

  Further, when the cooking container 40 is placed on the virtues 51 in the rising state of the temperature detection device 9 (when the cooking container 40 is placed), the contact body 13 is lowered and contacted as shown in FIG. The upper end of the body 13 and the upper end of the virtues 51 have the same height.

  And in the state which contact body 13 shown in Drawing 4 contacted the bottom of cooking vessel 40, contact body 13 is urged by the repulsive force which arises between permanent magnet 15 and electromagnet 16, The contact body 13 is pressed against the bottom surface of the cooking container 40 with a predetermined pressing force, and the contact body 13 reliably contacts the bottom surface of the cooking container 40.

  Next, the operation when the temperature detecting device 9 is switched between the lowered state and the raised state will be described in detail with reference to the flowchart of the elevation control subroutine of the temperature detecting device shown in FIG.

  First, at step # 001, it is determined whether or not an ignition operation is performed by the point fire extinguishing operation unit 21a.

  If it is determined in step # 001 that the ignition operation by the point fire extinguishing operation unit 21a has been performed, the process proceeds to step # 002, where the electromagnet 16 is energized and the process returns.

  On the other hand, when it is determined in step # 001 that the ignition operation by the point fire extinguishing operation unit 21a is not performed, the process proceeds to step # 003, and it is determined whether or not the extinguishing operation by the point extinguishing operation unit 21a is performed.

  And when it determines with the fire extinguishing operation by the point fire extinguishing operation part 21a having been performed by step # 003, energization to the electromagnet 16 is stopped by step # 004 (when the electromagnet 16 is not energized) (Remaining the state where the electromagnet 16 is not energized) returns.

  If it is determined in step # 003 that there is no fire extinguishing operation by the point fire extinguishing operation unit 21a, the process directly returns.

  That is, in the gas stove A of this embodiment, as shown in FIG. 5, it is switched to the rising state by issuing an ignition command by the point fire extinguishing operation unit 21 a, and switched to the descending state by issuing a fire extinguishing command by the point fire extinguishing operation unit 21 a. It is configured to be. Therefore, since the rising state and the lowering state are switched by the point fire extinguishing operation of the point fire extinguishing operation unit 21a, it is possible to realize a gas stove with good usability (a gas stove equipped with a temperature detection device).

  In the gas stove A according to this embodiment, the point fire extinguishing operation unit 21a for instructing the point fire extinguishing to the standard burner (a stove burner) 1a and the control means (not shown) perform the above-described lowered state and raised state. Although the switching means for switching is configured, the configuration of the switching means is not limited to the configuration of this embodiment, and other configurations can be used as described in the section of another embodiment below. It is.

  Further, in the gas stove A according to this embodiment, as described above, the permanent magnet is disposed on the lower end side (position below the center) of the moving side support cylinder 12, and the electromagnet 16 is disposed on the fixed side support member 11. Since it is arranged at the lower end side (a position below the center), the influence of heat on the permanent magnet 15 and the electromagnet 16 due to the heating of the standard burner (a stove burner) 1a is suppressed, and a highly reliable gas stove is provided. Can be provided.

  However, the configuration in which the permanent magnet is disposed in the lower portion of the moving side support cylinder 12 and the electromagnet 16 is disposed in the lower portion of the fixed side support member 11 is an arbitrary configuration. The electromagnet 16 may be disposed at a position other than the lower portion of the stationary support member 11.

[Another embodiment]
In the above-described embodiment, the case where the point fire extinguishing operation unit 21a for instructing the point fire extinguishing to the standard burner (combustor) 1a and the control means (not shown) constitute the switching means has been described. The control means may constitute a switching means. In that case, it is configured to be switched to the raised state by energizing the control means by operating the power switch 24 and to be switched to the lowered state when the power to the control means is interrupted by operating the power switch 24.
It should be noted that the switching means may have another configuration.

  In this way, even when the power switch 24 and the control means constitute a switching means, the rising and falling states are switched by energizing and de-energizing the control means by the operation of the power switch 24. A gas stove equipped with a good temperature detection device can be realized.

  In the above embodiment, the drop-in stove has been described as an example. However, the present invention can also be applied to a table stove.

  Further, in the above-described embodiment, the standard burner has been described as an example in which the standard burner includes the temperature detection device for detecting the temperature and the switching unit that switches the temperature detection device between the lowered state and the raised state. Not only the standard burner but also a high thermal power burner or a small burner may be configured to include a temperature detection device and a switching means.

  The present invention is not limited to the above embodiment in other points, and various modifications can be made within the scope of the present invention.
