Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooker equipped with a temperature sensor to automatically stop the fuel supply to the burner and extinguish the burner when the pot bottom temperature reaches a set temperature.

[0002]

2. Description of the Related Art In a cooker such as a gas table stove that is equipped with a temperature sensor to automatically stop the fuel supply to the burner when the temperature of the pot bottom reaches a set temperature, the pot bottom temperature is adjusted by touching the pot bottom. When cooking foods such as stir-fried foods and grilled foods (hereinafter referred to as high-temperature cooking), the temperature sensor that detects them is temporarily separated from the bottom of the pan so that it does not touch the bottom of the pan so that it does not touch the bottom of the pan. When the dish is displaced and cooked with tempura (hereinafter referred to as low-temperature cooking), it is desirable for safe use that the temperature sensor is in an operating position where it touches the bottom of the pot and senses the bottom temperature.

[0003] Therefore, conventionally, the temperature sensor in the inoperative position which does not contact the bottom of the pan during high temperature cooking is returned to the operating position in contact with the bottom of the pan required for low temperature cooking by igniting or extinguishing the burner to perform high temperature cooking. There is one that eliminates the inconvenience in use due to forgetting to return it later (see, for example, Japanese Patent Publication No. 5-19050).

The above-mentioned conventional device is composed of a drive device which is composed of a cam body or a rack and pinion coaxial with the operation knob, and a displacement device which is composed of a displacement guide, a displacement lever, a support and a holding magnet. The operating means is used to return the temperature sensor in an inoperative position not in contact with the bottom of the pot to the operating position in contact with the bottom of the pot by ignition operation or extinguishing operation by the operation knob.

More specifically, at the ignition position of the operating knob, the tip end side of the displacement burner can be raised, the temperature sensor can be displaced to the inoperative position, and at the fire extinguishing position, the drive device presses the tip end side of the displacement lever. However, the temperature sensor is in the operating position, and when the temperature sensor is in the inoperative position, it is returned to the operating position through the drive device by the ignition operation of the operating knob.

[0006]

However, since there is no certainty in the displacement of the temperature sensor between the operating position and the non-operating position due to the point extinguishing operation of the operating knob, forgetting to return it to the operating position may occur. It is not easy to use.Furthermore, the manual operation knob of the displacement lever of the displacement device is installed side by side with the ignition operation knob, etc. on the front panel. There is a problem in that the structure of the displacement device and the drive device is complicated, such as a space dedicated to the lever is required, and the cost is also high.

Therefore, according to the present invention, in the predetermined operation range of the blinking operation means, the displacement of the temperature sensor to the inactive position where it does not contact the pan bottom and the displacement to the operating position where it contacts the pan bottom can be reliably performed. It is intended to provide a cooking device that is safe in use and that is structurally simplified to reduce costs.

[0008]

In order to achieve the above object, the cooker of the present invention provides a temperature sensor for contacting the bottom of a pan to detect the temperature of the bottom of the pan and a temperature of the bottom of the pan preset by the temperature sensor. When sensed, in a cooker provided with fuel control means for stopping fuel supply to the burner, and position changing means for displacing the temperature sensor into an operating position in contact with the pan bottom and an inactive position not in contact with the pan bottom, In the operating range between the predetermined ignition position of the operating means for flashing the temperature-sensitive sensor and the high-temperature heating and cooking position in the operating position further beyond the ignition position, the operating position in contact with the pan bottom and the contact position not in contact with the pan bottom. It is characterized by having an interlocking mechanism for displacing it to the operating position.

Further, it is also characterized in that it is equipped with a point fire extinguishing interlocking mechanism that interlocks the temperature sensor with a blinking operation and moves it to an inoperative position where it touches the bottom of the pot by an ignition operation and to an inoperative position where it does not come into contact with the pot bottom at the extinguishing position. And

[0010]

In the cooking device of the present invention, the temperature sensor is in an operating position where it touches the bottom of the pot during low temperature cooking, and the pot bottom temperature is sensed. Therefore, when the temperature sensor senses the preset pot bottom temperature, the signal is output. The fuel control means is operated to stop the fuel supply to the burner and extinguish the burner.

During high temperature cooking, the temperature sensor is in an inoperative position where it does not come into contact with the bottom of the pan and is separated from the bottom of the pan and does not sense the temperature of the bottom of the pan. Therefore, high temperature cooking can be performed.

Therefore, in the invention of claim 1, when high-temperature cooking is performed, the blinking operation means is rotated from the extinguishing position to the ignition position to ignite the burner, and then the blinking operation means is predetermined ignition. When the rotary operation is performed from the position to the high-temperature cooking position, which is an operating position that further exceeds the ignition position, the temperature-sensitive sensor is lowered and displaced to the inoperative position via the interlocking mechanism. As a result, the desired high temperature cooking can be performed properly.

When the burner is extinguished after the high-temperature heating cooking is completed, the temperature-sensitive sensor operates the interlocking mechanism during the period from the high-temperature heating cooking position to the ignition position when the flashing operation means is returned from the high-temperature heating cooking position to the fire extinguishing position. Through the inoperative position to the operating position, and prepares for the next low temperature heating cooking. From the ignition position to the fire extinguishing position, the blinking operation means rotates regardless of the temperature sensor to extinguish the burner. As a result, the temperature sensor is not forgotten to return to its operating position.

According to the second aspect of the present invention, when the blinking operation means is in the fire extinguishing position, the temperature sensor is in the inoperative position where it does not contact the bottom of the pan, so that the blinking operation means is moved from the fire extinguishing position to the ignition position during low temperature cooking. When the rotary operation is performed, the temperature sensor is moved upward to the operating position through the point fire extinguishing interlocking mechanism along with the ignition to the burner. When the rotary operation is performed from the ignition position to the fire extinguishing position, the temperature sensor is also detected at the same time as the burner extinguishes. To the inoperative position via the point extinguisher interlocking mechanism. As a result, during low temperature cooking, the temperature sensor surely moves upward to the operating position, so it is not forgotten to return the temperature sensor to the operating position, and at the fire extinguishing position, the temperature sensor descends to the inactive position. Therefore, the temperature sensor is not damaged or disturbed when the pot is placed or when cleaning.

When performing high-temperature cooking, the blinking operation means is rotated from the extinguishing position to the high-temperature cooking position. When the blinking operation means is rotated from the extinguishing position to the ignition position, the burner is turned on. Although the temperature sensor is once displaced to the operating position by the above-mentioned reason together with the ignition, if the blinking operation means is continuously rotated from the ignition position to the high temperature cooking position at the operation position further beyond the ignition position. ,
The temperature sensor is lowered and displaced again to the inoperative position via the point extinguisher interlocking mechanism. As a result, the desired high temperature cooking can be performed properly.

When the burner is extinguished after the high-temperature cooking is completed, the temperature-sensitive sensor interlocks with the point extinguishing during the period from the high-temperature cooking position to the ignition position when the flashing operation means is returned from the high-temperature cooking position to the extinction position. Although it is temporarily displaced upward from the inoperative position to the operating position via the mechanism, if the blinking operation means is continuously rotated to the fire extinguishing position, the temperature sensing sensor is used together with the extinction of the burner between the ignition position and the extinguishing position. Based on the above reason, it is lowered and displaced again to the inoperative position. As a result, at the time of the next low temperature cooking, the temperature sensor surely moves upward to the operating position, so it is not forgotten to return to the operating position, and at the fire extinguishing position, the temperature sensor moves downward to the inactive position. Therefore, the temperature sensor is not damaged or disturbed when the pot is placed or when cleaning.

In the inventions of claims 1 and 2, when the blinking operation means is rotated from the high-temperature heating cooking position to the ignition position when the burner extinguishes upon completion of high-temperature heating cooking, the temperature sensor is displaced upward to the operating position. If the turning operation of the blinking operation means is stopped at the ignition position, the high-temperature cooking can be switched to the low-temperature cooking for continuous use.

It is arranged in the center of the stove burner 3 so that it can be displaced between an operating position where the pot bottom temperature is sensed and a non-operating position where the pot bottom temperature is not sensed apart from the pot bottom.

Reference numeral 2 is a blinking operation knob which is a blinking operation means of the stove burner 3. In the first embodiment, the blinking operation knob 2 is moved from the predetermined fire extinguishing position a to the ignition position b or from the ignition position b to the extinguishing position. The rotating stove burner 3 can be turned on and off by rotating to a, and the high-temperature cooking position c or the high-temperature cooking position c from the ignition position b to the ignition position b in the operation position further beyond the ignition position. In the rotation operation range of, the temperature sensor 1 can be moved up and down via the interlocking mechanism A described later, and the temperature sensor 1 can be displaced between an inoperative position where it does not contact the pan bottom and an operating position where it contacts the pan bottom. Has become. In addition, each position a, b, c of the blinking operation knob 2
Then, for example, by slightly restricting the rotation of the blinking operation knob 2 with a click device (not shown) or the like, for example, the blinking operation knob 2 goes too far from the ignition position b to the high temperature cooking position side c during the ignition operation. It is designed to prevent erroneous operations such as.

In the second embodiment, the blinking operation knob 2 is rotated from a predetermined fire extinguishing position a to the ignition position b or from the ignition position b to the fire extinguishing position a, so that the stove burner 3 blinks together with the flashing operation knob 2 to be described later. The temperature-sensing sensor 1 can be moved up and down via the point fire extinguishing interlocking mechanism A ′, and the temperature-sensing sensor 1 can be displaced between an operating position where it contacts the bottom of the pan and an inoperative position where it does not contact the bottom of the pan. Then, from the ignition position b to the ignition position b
In the high-temperature cooking position c which is further beyond the operating position or in the turning operation range from the high-temperature cooking position c to the ignition position b, only the temperature sensor 1 is moved up and down via a point extinguishing interlocking mechanism A'described later. By moving, the temperature sensor 1 can be displaced between an inoperative position where it does not contact the bottom of the pan and an operating position where it contacts the bottom of the pan. In the second embodiment as well, the positions a, b and c of the blinking operation knob 2 are lightly regulated by the click device.

As a mechanism for interlocking the blinking operation knob 2 and the temperature sensor 1, the interlocking mechanism A of the first embodiment is used.
Is a cam plate 9 fixed to the shaft 8 of the blinking operation knob 2 and rotation of the blinking operation knob 2 from the ignition position b to the high temperature cooking position c or from the high temperature heating cooking position c to the ignition position b by the cam plate 9. It is composed of a driving side lever 10 which is driven only at the time of operation and a driven side lever 12 which is pivotally supported by a pivot pin 11 on an operating shaft 7 which moves the temperature sensor 1 up and down. A substantially central portion is pivotally supported by a support leg plate 13 by a pivot shaft 14, and the driven side lever 12 is pivotally supported by a pivot shaft 16 at a substantially central portion of the driven side lever 12, and both levers 10, 12 are connected by a pivot pin 17. The temperature sensor 1 can be displaced between an inoperative position where it does not contact the pan bottom and an operating position where it contacts the pan bottom in the operating range between the ignition position b of the blinking operation knob 2 and the high temperature cooking position c. There is.

In the point fire extinguishing interlocking mechanism A'of the second embodiment, the operation cam plate 9'fixed to the shaft 8 of the blinking operation knob 2 is in contact with the cam surface 9a of the operation cam plate 9 ', and its tip side 29a is in contact. A spring rod (torsion spring) 29 that moves up and down, and the spring rod 2
9 and an interlocking lever 31 which is rotated clockwise in the drawing with a pivot 30 as a fulcrum, and the movable cylinder 26 is urged upward by a spring 28 when the interlocking lever 31 is rotated clockwise in the drawing. Against this, the leg rod 32 integrated with the movable barrel 26 and the engaging pin 33 provided on the leg rod 32 pulls it downward, and when the interlocking lever 31 releases the pulling force, the spring 28 biases it upward. To lift it up to
In the operating range between the fire extinguishing position a and the ignition position b of the blinking operation knob 2, the temperature sensor 1 can be displaced to the inoperative position where it does not contact the pan bottom and the operating position where it contacts the pan bottom together with the blinking of the burner. In the operating range between the high temperature cooking position c and the high temperature cooking position c, only the temperature sensor 1 can be displaced between an inoperative position where it does not contact the pan bottom and an operating position where it contacts the pan bottom.

In the first embodiment, B is a gas control body equipped with an ignition cock or the like which works in conjunction with the blinking operation knob 2.
Reference numeral 9 is a soup saucer, and 21 is a gas nozzle. In addition, Example 1
In 2 and 2, 18 is Gotoku, 20 is a mixing tube of the stove burner 3, and 22 is a pot placed on the Gotoku 18.

The operation of the above structure will be described below.

In the first embodiment, when the blinking operation knob 2 is at the fire extinguishing position a or the ignition position b, that is, at the time of low temperature cooking, the temperature sensor 1 is not related to the interlocking mechanism A. The temperature sensor 1 is not operated in the operation range between the fire extinguishing position a and the ignition position b of the blinking operation knob 2, and is displaced upward to an operation position in contact with the pan bottom. Therefore,
When the pot 22 is placed on the Gotoku 18, the temperature sensor 1 contacts the bottom of the pot and detects the temperature of the bottom of the pot (see FIGS. 1 and 2). Therefore, the bottom of the pot is overheated and the temperature sensor 1 is preset. When the temperature is sensed, the controller receives the signal and closes the gas control valve in the gas supply path to cut off the gas supply to the stove burner 3 to extinguish the burner 3 for safety.

Next, when high temperature cooking is performed, the blinking operation knob 2 is rotated from the fire extinguishing position a to the high temperature heating cooking position c, but is rotated from the fire extinguishing position a to the ignition position b. By the way, the flash burner 3 is ignited by a blinking device (not shown). After that, when the blinking operation knob 2 is further rotated from the ignition position b to the high temperature cooking position c, the cam plate 9 integrated with the blinking operation knob 2 rotates the drive side lever 10 in the clockwise direction in the figure with the pivot 14 as the fulcrum. In order to move, the driven lever 12 rotates counterclockwise in the drawing with the pivot 16 as a fulcrum, and the actuating shaft 7 connected to the driven lever 12 by the pivot pin 11 resists an upward biasing force. Then, the temperature sensor 1 integrally spring-energized with the actuating shaft 7 descends together with the movable holder 6 and descends to an inoperative position where it does not come into contact with the pan bottom (see FIG. 3). Therefore, since the temperature sensor 1 is separated from the bottom of the pot, the temperature of the bottom of the pot is not sensed by the temperature sensor 1, and desired high temperature cooking can be properly performed.

At the end of the high temperature cooking, the blinking operation knob 2 is rotated from the high temperature cooking position c to the fire extinguishing position a to extinguish the stove burner 3.
During the period from the high temperature cooking position c to the ignition position b, the cam plate 9, both levers 10 and 12 and the operating shaft 7 are operated in the opposite manner to the displacement to the inactive position, and the temperature sensor 1 is interlocked. Since the holding in the non-operating position by the mechanism A is released, the temperature sensor 1 is moved upward by the upward biasing force together with the movable holder 6 and is displaced upward to the operating position in contact with the bottom of the pan to prepare for the next low temperature cooking ( (Refer to the state of FIG. 2 from the state of FIG. 3). When the blinking operation knob 2 is rotated to the fire extinguishing position a, the stove burner 3 is extinguished by the blinking device (see the state of FIG. 1).

In the second embodiment, when the blinking operation knob 2 is rotated from the fire extinguishing position a to the ignition position b during low temperature cooking, the stove burner 3 is ignited by the blinking device (not shown) and the blinking operation is performed at the same time. In order to push down the tip side 29a of the spring rod 29 from a'to b'by the cam surface 9a of the operating cam body 9'integral with the knob 2 against the spring force (from the solid line in FIG. 7 to the solid line in FIG. 6). Refer to the state of), this spring rod 29
The lifting and holding of the base end side 31a of the interlocking lever 31 due to is released. Therefore, since the interlocking lever 31 is in the free state, the holding of the temperature sensor 1 in the inoperative position by the tip end side 31b of the interlocking lever 31 (see the state of FIG. 5) is released, and the temperature sensor 1 is moved by the spring 28. It moves upward together with the movable cylinder 26 and the lever rod 32, and is displaced up to an operating position where it comes into contact with the pot bottom, and comes into contact with the pot bottom to detect the pot bottom temperature sensor 1.
(See the solid line in FIG. 4). Therefore, desired low temperature cooking can be performed appropriately. At this time, the front end side 31b of the interlocking lever 31 is lifted by the engagement pin 33 and pivots counterclockwise in the drawing, returns to the upper right position in the drawing, and prepares for operation to the next inoperative position (see FIG. 4). See the state of the solid line).

When the blinking operation knob 2 is turned from the ignition position b to the fire extinguishing position a to extinguish the fire of the stove burner 3 at the end of the low temperature heating and cooking, the cam surface 9a of the operating cam plate 9'is moved. The tip end side 29a of the spring rod 29 is moved and returned upward by the spring force from b'to a'and the base end side 31a of the interlocking lever 31 is lifted by the spring rod 29 to raise the interlocking lever 3
1 is rotated clockwise with the pivot 30 as a fulcrum, and the temperature sensor 1 is moved to the movable cylindrical body 2 at the tip end side 31b of the interlocking lever 31.
6. Since the temperature sensor 1 is pulled down together with the lever rod 32 against the spring 28, the temperature sensor 1 is displaced down to an inoperative position where it does not contact the bottom of the pan, and is ready for the next high-temperature cooking or low-temperature cooking (see FIGS. 4 and 6). (Refer to the states shown in FIGS. 5 and 7 from the state of the solid line).

Next, when performing high temperature heating cooking, the blinking operation knob 2 is rotated from the fire extinguishing position a to the high temperature heating cooking position c, but the blinking operation knob 2 is extinguished position a.
When the rotary operation is performed from the to the ignition position b, the flash burner 3 is ignited by a blinking device (not shown), and at the same time, the temperature sensor 1 is attached to the cam surface 9a of the operation cam body 9 ', the spring rod 29, and the interlocking lever 31. Although it is temporarily displaced upward to the operating position through the point fire extinguishing interlocking mechanism A ', the blinking operation knob 2 is turned from the ignition position b to the high temperature cooking position c, and the blinking operation knob 2 is moved. The spring rod 29, which is in contact with the cam surface 9a of the operating cam body 9 ', causes the tip side 29a of the operating cam body 9'to move upward and return from b'to a'by the spring force along the cam surface 9a of the operating cam body 9'. (Refer from the solid line state to the chain line state in FIG. 6). Therefore, the spring rod 29 lifts the base end side 31a of the interlocking lever 31 to rotate the interlocking lever 31 in the clockwise direction in the drawing, and the tip end side 31b pulls down the temperature sensor 1 to displace it to the inoperative position. High temperature cooking can be done properly.

At the end of the high temperature cooking, the blinking operation knob 2 is rotated from the high temperature cooking position c to the fire extinguishing position a to extinguish the stove burner 3.
The blinking control knob 2 moves from the high temperature cooking position c to the ignition position b.
When it is rotated up to, the cam rod 9a of the actuating cam body 9'pushes down the spring rod 29 against its spring force to move its tip side 29a from a'to b '.
The lifting and holding of the base end side 31a of the interlocking lever 31 by 9 is released, and the temperature sensor 1 is temporarily displaced upward to the operating position by the above reason, but when the blinking operation knob 2 is continuously rotated to the fire extinguishing position a, The spring rod 29, which is in contact with the cam surface 9a of the operating cam body 9'integrated with the blinking operation knob 2, has its tip side 29a moved back from b'to a'by the spring force along the cam surface 9a. 31 is a spring rod 29
Then, the base end side 31a is lifted and rotated clockwise in the drawing. Therefore, the temperature sensor 1 is pulled down by the tip end side 31b of the interlocking lever 31 and is lowered and displaced to the inoperative position (see FIG. 6).
Preparation for next low temperature cooking or high temperature heating cooking).

In the first and second embodiments, when the blinking operation knob 2 is rotated from the high temperature heating cooking position c to the ignition position b when the burner extinguishes upon completion of high temperature heating cooking, the temperature sensitive sensor 1 rises to the operating position. Since it is displaced, if the turning operation of the blinking operation knob 2 is stopped after returning from the high temperature cooking position c to the ignition position b, the stove burner 3 is switched on from the high temperature cooking to the low temperature cooking continuously. Can be used.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. is there. For example,
In the first and second embodiments, the blinking operation knob is exemplified as the blinking operation means, but the blinking operation lever may be used as the blinking operation means.

[0036]

According to the inventions of claims 1 and 2 of the cooker of the present invention described above, the blinking operation means and the temperature-sensitive sensor are interlocked in the operation range of the blinking operation means to heat the temperature-sensitive sensor at a high temperature. Since there is no forgetting to return when cooking at low temperature, along with a reliable displacement to the inoperative position that does not contact the pot bottom during cooking and the operating position that contacts the pot bottom during low temperature heating,
In addition to being safe in use, there is an effect that cost reduction can be achieved because the structure can be simplified because no dedicated operating means is required. It also has the effect that it can be used continuously by switching from high temperature cooking to low temperature cooking.

Further, in the invention of claim 2, since the temperature sensor is in the inoperative position when the blinking operation means is extinguished, the temperature sensor is damaged or obstructs when the pot is placed or when cleaning. It has the effect of never happening.
