There is a stove with a large number of heating parts, such as a stove with three mouths, a stove with three mouths, and a grill. However, the correspondence between the heating part and the control on the front of the stove that turns the heating part on / off is glance It's not always easy to see. For this reason, even those who are accustomed to using the stove usually hurry up cooking or complicated cooking, inadvertently turn on the operator that should be turned on carelessly, ignite the wrong heating part and heat it up May start.
[0003]
Conventionally, in order to prevent this, there has been known a stove in which the color of the operator of the grill is the same color as the color of the grill door and the color of the burner is different from that of the grill operator (see, for example, Patent Document 1). . However, in this stove, although the distinction between the burner operator and the grill operator is readily apparent, the distinction between the plural burners cannot be seen immediately.
[0004]
On the other hand, when a lamp is installed in the operating element or a lamp is provided near the operating element and a cooking container such as a pan is placed on the burner, the operating lamp corresponding to the burner on which the cooking container is placed There is also known a stove that blinks to notify the operator (for example, see Patent Document 2).
[0005]
However, heating the cooking container with a burner is not only for cooking with a new cooking container placed in the burner part, but also to reheat the remaining food in the cooking container placed in the burner part. There is also a case of heating. In this case, it is not known which operation element should be turned on unless the cooking container is replaced.

[0014]
DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the stove according to the present embodiment has a glass top plate 3 that uses heat-resistant glass (ceramics) at the top surface of the stove body 2. It covers and is suspended from the opening of the worktop 4 by locking the flange around the upper end of the stove body 2 around the opening provided in the worktop 4 of the kitchen.
[0015]
A plurality of heating parts by gas burners are formed on the glass top plate 3. That is, the internal flame type gas burners 5 and 6 accommodated in the stove main body 2 face the left and right positions near the front of the glass top plate 3 from the burner opening, and the internal flame type gas burner 7 having a smaller diameter is located behind the top plate 3. It faces the burner opening at the center position. Five virtues 5a, 6a, 7a are placed around the gas burners 5, 6, 7 of the top plate 3. A box-shaped grill 8 is formed at the center of the stove body 2, and a heating unit (radiation unit) using a gas burner is provided on the ceiling of the grill 8. The opening on the front surface of the grill 8 located on the front surface of the stove body 2 is closed by a door 8a that also serves as a handle portion of the soup pan. The soup pan is provided in the grill 8 so as to be freely accessible.
[0016]
On the front surface of the stove body 2, operation panels 9 are provided on both sides of the grill door 8a, and operation buttons 10 to 13, which are push-in operators for turning on / off the burner 5 and the like, are attached to the operation panel 9. Yes. The operation buttons 10 and 11 on the left panel 9 correspond to the rear burner 7 and the left burner 5, respectively, and the operation buttons 12 and 13 on the right panel 9 correspond to the right burner 6 and the grill 8, respectively.
[0017]
The correspondence relationship between the ignition buttons 10 to 13 and the burners 5 to 7 and the grill 8 serving as heating units is not necessarily understood at a glance. For this reason, if you are a regular cook and are used to using a stove, you can't make a mistake easily. Incorrect operation of the button to be turned on may ignite the wrong heating part.
[0018]
Therefore, in the present invention, a detection means for detecting that the cook's hand approaches or touches the operation button and a notification means for the cook are provided, and the detection means detects the approach or contact of the hand to the operation button. When it does, it is made to alert | report which heating part the heating part which a cook is going to operate with an operation element is an alerting | reporting means.
[0019]
In the present embodiment, an infrared sensor (not shown) is used as the detection means, and this is incorporated into each of the operation buttons 10 to 13 to detect the approach of the hand to the operation button. An infrared sensor may be installed near each operation button. Further, a light emitting element is used as a notification means, light emitting elements 15, 16, 17 are attached to the back side position of the top plate 3 around the five virtues 5a, 6a, 7a of the burners 5, 6, 7, and the upper side of the door 8a of the grill 8 The light emitting element 18 was attached to the back surface of the upper right corner of the glass panel 8b. When the cook approaches his / her hand to the operation button and the detection means detects it, the light emitting element of the burner or grill corresponding to the operation button to which the hand has approached is turned on.
[0020]
When the light emitting elements 15 to 17 under the top board 3 are lit, the light emitting elements can be seen to be lit through the glass top board 3, so that the cook can determine which burner is turned on / off by the operation button approaching the hand. I understand. Similarly, when the light emitting element 18 on the back surface of the glass panel 8b of the grill 8 is turned on, the cook knows whether or not the grill 8 is turned on / off by an operation button approaching the hand.
[0021]
There are two types of lighting of the light emitting element: blinking or continuous lighting. In this embodiment, when the approach of the hand to the operation button is detected, the light emitting element blinks and the heating unit (burner or grill) is in use. As for the continuous lighting of the light emitting element, it can be seen that the heating part is in use by the light emitting element. Hereinafter, the notification control of the heating unit in the present embodiment will be described with reference to the flowchart shown in FIG. The burner was taken as an example when using the small burner 7 on the back side.
[0022]
The control flow starts when the gas stove can be used, and is always in a state of executing the control flow. When the cook approaches his or her corresponding operation button 10 to ignite the burner 7, the detection means detects it (step S1), and the light emitting elements 17 around the burner 7 blink (step S2). The cook who is going to ignite the burner 7 sees that the light emitting element 17 around the burner 7 blinks at the time of the button 10, and understands that the button 10 should be pushed.
[0023]
The cook subsequently presses the operation button 10 to ignite the burner 7. However, when the cook releases the hand without pressing the operation button 10 (step S4), the detection means detects it and the light emitting element 17 is turned off (step S4). S5), returning to step S1. When the cook presses the operation button 10 to ignite the burner 7 (step S3), the lighting state of the light emitting element 17 is switched from blinking to continuous lighting (step S6), and the continuous lighting state continues while the burner 7 is in use.
[0024]
When cooking of the food in the pan is finished and the cook approaches the operation button 10 to extinguish the burner 7, the detection means detects it (step S7), and the light emitting element 17 blinks from continuous lighting. (Step S8). The cook who is going to extinguish the burner 7 sees that the light emitting element 17 around the burner 7 blinks with the operation button 10 and understands that the operation button 10 should be pressed. When the operation button 10 is pressed to extinguish the burner 7 (step S9), the light emitting element 17 is turned off (step S10), and the notification control flow ends.
[0025]
When the burners 5 and 6 or the grill 8 are used, it is the same as the burner 7. In any case, the correspondence between the operation buttons 11, 12, 13 and the burners 5, 6, and the grill 8 can be seen at a glance by the flashing of the light emitting elements 15, 16, and 18, and the burners 5, 6, and the grill 8 are ignited without erroneous operation. It can also be extinguished. The same applies when two or more of the burners 5, 6, 7 and the grill 8 are used simultaneously.
[0026]
In the above embodiment, the light emitting elements 15 to 18 which are lighting means are used as the notification means, but the notification means is provided at an appropriate place such as the front surface of the stove body 2 as shown by an imaginary line in FIG. it may be used in combination with the lighting means and audio means 14. For example, when the detection means detects that the hand has approached the operation buttons 10, 11, 12, and 13, the audio means 14 is turned on / off by the operation buttons 10, 11, 12, and 13 until the hand leaves the operator. The heating parts to be turned off are the burners 7, 5, 6 and the grill 8, for example "back burner", "left burner", "right burner", "grill" Inform by voice guidance. Even with such voice means, the correspondence between the operation buttons 10, 11, 12, 13 and the burners 7, 5, 6, and the grill 8 can be immediately understood, and the burners 5, 6, 7, and the grill 8 are ignited without the operation. It can also be extinguished. If the lighting means and the sound means are used in combination, the effect of preventing erroneous operation is further improved.
[0027]
In the above embodiment, the detection means detects the approach of the hand to the operation button using the infrared sensor, but the hand is used by utilizing the fact that the capacitance changes due to the hand touching the operation button. You may use the thing of the system which detects the contact of this. Notification control similar to the above is performed by detecting the contact of the hand with the operation button.
[0028]
The operation element is a button type operation button, but it may be a push-type knob. The top plate 3 is made of glass, but may be made of aluminum or stainless steel. In that case, lighting of the light emitting element is made visible through a slit or opening provided in the top plate in accordance with the position of the light emitting element under the top plate. The slits and openings should be covered with a transparent plate to prevent the broth spilled on the top plate 3 from falling into the stove body 2.
[0029]
Moreover, although the stove has shown what has the heating part by a gas burner, it can be made into the thing of various systems, such as providing the heating part by an induction heating coil, or the heating part by resistance heating.
[0030]
【The invention's effect】
As is apparent from the above description, according to the stove of the present invention, the detection means for detecting the approach or contact of the hand of the cook to the operation element such as an infrared sensor or an electrostatic sensor, and the heating unit are installed. A notification means for notifying the cook of the heating unit such as the light emitting element, and when the detection means detects the approach or contact of the hand to the operation element, the notification means is used by the cook to operate the operation element. Since the heating unit is informed, the correspondence between the operation element and the heating unit can be readily understood, and erroneous heating unit ON / OFF due to erroneous operation of the operation element can be surely eliminated.
