(Step 300). When in the object detection state, in step 302, the control unit H determines whether or not the high thermal power burner 1a and the standard burner 1c are at the gas burner retracted position, and the high thermal power burner 1a and the standard burner 1c are retracted from the gas burner. If not, the electric motors 15a and 15c are operated to move the high thermal power burner 1a and the standard burner 1c to the gas burner retracted position (step 304). On the other hand, when the high thermal power burner 1a and the standard burner 1c are in the gas burner retracted position, the process returns to the beginning of the separation control. That is, when the object sensor S is in an object detection state in which the object sensor S detects that an object has entered the set area around the small burner 1b from the outside, the control unit H uses the high burner 1a and the standard burner 1c as the gas burner. Move to the retreat position and try to place a heated object such as a pan on the hand or clothes of an operator who is trying to pick up a heated object such as a pot placed on Gotoku 6b The operator's hand, clothing, and the like are controlled so as to be separated from the high thermal power burner 1a and the standard burner 1c, and the operator is free from dangers such as burns and ignition of clothing.

  Further, the control unit H determines whether or not the high heating power burner 1a and the standard burner 1c are in the heating position when the object is not detected (step 306). The control unit H returns to the beginning of the separation control when the high thermal power burner 1a and the standard burner 1c are in the heating position, and when the high thermal power burner 1a and the standard burner 1c are not in the heating position, the control unit H returns The electric motors 15a and 15c are actuated to move the burner 1c to the heating position (step 308). That is, when the object sensor S is in an object non-detection state indicating that no object has entered the set area around the small burner 1b, the control unit H covers the high burner 1a and the standard burner 1c. It is comprised so that it can move to a heating position and the heating of the to-be-heated material using the high thermal power burner 1a and the standard burner 1c can be started.

  And the space | interval of a gas burner evacuation position and a heating position is set so that it may become large as the flame of a near side gas burner becomes large. In other words, the larger the flame of the front gas burner, the more the five virtues 6b are separated from the flame of the front gas burner. As a result, when the flame of the near side gas burner is large, even if the operator tries to handle the object to be heated placed on the Gotoku 6b by hand, the flame of the near side gas burner does not cause burns or ignition to clothes. Can be.

<Fourth embodiment>
In the present embodiment, it is considered that the separation command has been issued when the object sensor S is in the object detection state, the heating powers of the high-power burner 1a and the standard burner 1c that are the front side gas burners are reduced, and the front side gas burner is provided. The above embodiment is configured such that the high-temperature burner 1a and the standard burner 1c are moved to the gas burner retracted position so that the five virtues 6b and the flames of the high-power burner 1a and the standard burner 1c as the front side gas burners are separated. Different from form. Hereinafter, the present embodiment will be described, but the description similar to that of the above embodiment will be omitted.

The structure of the gas cooker of this embodiment is the same as the structure shown in FIG.9 and FIG.10, and each of the high thermal power burner 1a and the standard burner 1c which is a near side gas burner is shown in FIG. A front side gas burner lifting / lowering means Ef for moving up and down between a heating position for heating the near side heated object and a gas burner retracting position below the heating position as shown in FIG. 10B is provided.
Next, the front side gas burner elevating means Ef is operated by the control unit H, and the flow rate control valves 19a and 19c are operated to raise and lower the high thermal power burner 1a and the standard burner 1c between the heating position and the gas burner retracting position. A flow chart of separation control for separating the five virtues 6b from the flames of the high thermal power burner 1a and the standard burner 1c by adjusting the size of the flame of the front gas burner will be described with reference to FIG. In the present embodiment, the control unit H stores a control content being executed, that is, whether or not a command to reduce the thermal power is given to the high thermal power burner 1a and the standard burner 1c by a flag as described later, and It is assumed that it is memorized that a command to move the high thermal burner 1a and the standard burner 1c to the heating position is given and a command to move the gas burner to the retreat position.

  The control unit H determines whether the object sensor S is in an object detection state in which it is detected that an object has entered the set area around the small burner 1b from the outside, or is in an object non-detection state. When in the detection state, it is considered that a separation command for separating the five virtues 6b and the flames of the high-power burner 1a and the standard burner 1c as the front side gas burner has been issued, and when in the object non-detection state, a separation release command is issued. (Step 400). When in the object detection state, in step 402, the control unit H determines whether or not flag = 1. When the flag is not 1, the flow control valves 19a and 19c are operated so as to reduce the thermal power of the high-power burner 1a and the standard burner 1c, which are the front gas burners, to, for example, the minimum thermal power, and the high-thermal power burner 1a and the standard burner 1c are The electric motors 15a and 15c are operated to move to the gas burner retracted position (step 404), and the control unit H sets flag = 1 (step 406). On the other hand, when the flag is 1 in step 402, the control unit H is reducing the thermal power of the high thermal power burner 1a and the standard burner 1c, which are the front gas burners, and the high thermal power burner 1a and the standard burner 1c are gas burners. Returning to the beginning of this separation control, assuming that it is in the retracted position. That is, when the object sensor S is in the object detection state in which the object sensor S detects that an object has entered from the outside into the set region around the small burner 1b, the control unit H reduces the thermal power of the front gas burner, and By moving the high thermal power burner 1a and the standard burner 1c to the gas burner retreat position, the burn of the front gas burner is caused to retreat with respect to the operator's hand and clothing reaching the back gas burner. It is configured to reduce the risk of ignition to clothing and clothing.

  Further, when the control unit H is in the object non-detection state, it determines whether or not flag = 0 in step 408. When the flag = 1, it is determined that the object detection state has been switched to the object non-detection state, and the control unit H changes the heating power of the high-power burner 1a and the standard burner 1c, which are the front gas burners, before responding to the isolation command. The electric motors 15a and 15c are operated to move the high thermal power burner 1a and the standard burner 1c to the heating position (step 410), and the flag is set to 0 (step 412). That is, when the object sensor S is in an object non-detection state indicating that no object has entered the set area around the small burner 1b from the outside, the control unit H performs proper cooking with the front gas burner. It is configured to adjust to the firepower that is.

  Thus, by performing both the downward movement of the front side gas burner and the reduction of the thermal power, the downward movement amount and the thermal power reduction amount can be reduced as compared with the case where each of them is performed independently.
