  Next, another embodiment will be described. In the present embodiment, when the notification is output from the sound output means 7, the control section 5 performs control so that the notification is output from the sound output means 7 closest to the heating unit to be notified.

In the present embodiment, the sound output means 7 corresponds to the left gas stove 12a corresponding to the left gas stove 12a, the middle sound output means 7b corresponding to the middle gas stove 12b and the grill 13, and the right gas stove 12c to the right. When the sound output means 7c is associated with the left gas stove 12a, it is output from the left sound output means 7a, and when the medium gas stove 12b or the grill 13 is notified, the medium sound output is output. When outputting from the means 7b and notifying about the right gas stove 12c, it outputs from the right sound output means 7c.
.

  With the configuration as described above, when notification is made from the sound output means 7, the nearest heating unit (left) corresponding to the sound output means 7 (7a, 7b, 7c) from which the notification sound or the like is output. Since it is a notification about the gas stove 12a, the middle gas stove 12b, the right gas stove 12c, and the grill 13), it is easy to understand which heating unit is the target.

  Next, still another embodiment will be described. In the present embodiment, the control unit 5 performs control so that the volume of the guidance output from the audio output unit 7 and the volume of the notification are different. It is preferable that the volume of the notification is larger than the volume of the guidance. Examples of guidance and notification include those shown in Table 1 above, but are not particularly limited.

  In the case of notification, there are many emergency cases where prompt action is required, and the notification performed in such an emergency alerts the user by outputting at a high volume as in this embodiment. It is possible to notify the user who is away from the cooking device, and when performing the guidance, the user is not in an emergency and is in the vicinity of the cooking device for operation. Thus, by outputting at a volume smaller than the notification, it becomes possible to avoid discomfort due to a large volume.

  Next, still another embodiment will be described. In this embodiment, in any one of the above embodiments, the sound field changing means 8 and the height detecting means are provided in addition to the configuration described above, and the output from the sound output means 7 is determined by the detection result of the height detecting means. Is controlled by the control unit 5 so as to be changed by the sound field changing means 8.

  The height detection means detects the height of the user or the height of the top of the head from the floor surface, and includes an infrared sensor or the like, and is provided in the main body casing 10.

  In the example shown in FIG. 4A, the sound field changing unit 8 is arranged so that the direction of the speaker 71 is changed so as to change the height position of the sound field formed by the output of sound or the like from the speaker 71 as the sound output unit 7. Is movable by driving means (not shown) such as a motor, and the output direction of the sound output from the speaker 71 can be changed up and down. The speaker 71 is accommodated in the main body casing 10, and the sound output direction of the speaker 71 is inclined from the front or the front diagonally downward to the front diagonally upward or upward about the rotation shaft 81 of the driving means such as a motor. A sound field (referred to as a low sound field) can be formed at a low position in a state where the sound output direction of the speaker 71 is forward or obliquely downward, and the sound output direction of the speaker 71 is obliquely upward or forward. A sound field (referred to as a high sound field) can be formed at a high position in an upward direction.

  By making it possible to change the low and high sound fields as described above, when a person with a short height or a person sitting in a wheelchair cooks, if the low sound field is formed because the position of the ear is low, guides and notifications etc. It becomes easy to hear sound, and when a person with a height of a predetermined level or more cooks in a standing position, since the position of the ear is high, if a high sound field is formed, it becomes easy to hear sound such as a guide or notification.

  Here, the standard for allocating between the low sound field and the high sound field is 140 cm or less (or a height value from the floor surface at the top of the head when sitting) of 140 cm or less (or a height from the floor surface when sitting). Less), a high sound field is preferably formed. The basis for 140 cm is that the height from the floor surface to the seat surface of the wheelchair is about 40 to 45 cm and the seat height is about 90 to 95 cm, so the height of the top when sitting on the wheelchair is about 140 cm, The height of an elderly woman whose height is the lowest by sex and age of an adult is about 150 cm. For this reason, a person who is sitting in a wheelchair is assumed to form a high sound field with 140 cm as the boundary value and the height exceeding 140 cm as the height of the top when the adult operates in a standing position. A low sound field is formed as the height of the top when a child or a child operates. In addition, you may make it set this boundary value suitably between 130-150 cm.

  Further, in the example shown in FIG. 4B, the sound field changing unit 8 is configured to change the height position of the sound field formed by the output of sound or the like from the speaker 71 as the sound output unit 7. The sound output from the projector is reflected in a predetermined direction by changing the direction of the reflecting plate 82. The speaker 71 is fixed inside the main casing 10 and is provided with a reflecting plate that is movable in the sound output direction by a driving means (not shown) such as a motor. The speaker 71 is centered on the rotation shaft 81 of the driving means. The sound output direction may be variable from the front or front diagonally downward to the front diagonally upward or upward, and a low sound field may be formed in a state where the voice output direction of the speaker 71 is forward or front diagonally downward. In addition, a high sound field can be formed with the sound output direction of the speaker 71 obliquely upward or upward.

  Further, in the example shown in FIGS. 4C and 4D, the sound field changing unit 8 is to change the height position of the sound field formed by the output of sound or the like from the speaker 71 as the sound output unit 7. A low-field speaker 71a fixed so that the sound output direction is forward or obliquely downward, and a high-field speaker 71b fixed so that the sound output direction is obliquely upward or upward. The control unit 5 has the function of the sound field changing means 8. Accordingly, a low sound field can be formed by outputting sound or the like from the low sound field speaker 71a as shown in FIG. 4C, and a high sound field speaker 71b as shown in FIG. 4D. A high sound field can be formed by outputting sound or the like.

It is a perspective view of a gas cooker. It is a schematic block diagram of the control system of the gas flow and combustion of a gas cooker same as the above. It is an enlarged view of a stove operation part. (A) (b) (c) (d) is a figure explaining a sound field change means.
