  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The heating cooker is a gas cooker equipped with a gas stove and a temperature sensor. First, the gas cooker will be described below.

  The gas cooker 1 shown in FIG. 1 is provided with a gas stove 12 and a grill 13 as heating means in a casing 10. The grill 13 is disposed inside a central portion of the casing 10 in the left-right direction, and a grill door 13a is disposed on the front surface thereof so as to be freely opened and closed. The top plate 11 of the casing 10 is provided with two gas stoves 12, one on each of the left and right sides. The gas stove 12 is composed mainly of a gas burner 2 having a burner cap 22 mounted on the burner body 21 and having a flame outlet around the burner body 21, and through the opening of the stove formed in the top plate 11 of the casing 10. It is exposed upward. Around the opening of the top plate 11, a virtues 14 in which a plurality of virtues claws 14 a are arranged in an annular shape are provided. This gas stove 12 is provided with a temperature sensor 3 as a temperature measuring means for measuring the temperature of the bottom of the container containing the food placed on the virtues 14 and controlling the combustion of the gas burner 2. . The temperature sensor 3 is provided with a temperature sensing portion such as a thermistor as a temperature measuring means at the upper end portion, and is disposed at a substantially central portion of the gas stove 12 at the lower portion of the container placed on the virtues 14. Contact to measure temperature.

  On the front surface of the casing 10, there are provided a stove operation unit 15 for manually operating the left and right gas stove 12, and a grill operation unit 16 for manually operating the grill 13. The operation commands from these operation units 15 and 16 are processed by the built-in control unit 5. The stove operation unit 15 gives the control unit 5 an ignition / extinguishment command for the gas burner 2, and gives the control unit 5 a command for adjusting the combustion amount of the gas burner 2. In this embodiment, the stove ignition / extinguishing operation unit and the stove heating amount adjusting operation unit are combined with the same dial-type knob unit 15a. More specifically, the knob portion 15a is switched between a normal position and a pushing position by a pushing operation, and an ignition command is given to the control unit 5 by changing the normal position to the pushing position, and the normal position is changed from the pushing position. Thus, a fire extinguishing command is given to the control unit 5, and it functions as a stove ignition / fire extinguishing operation unit by performing a push operation in this way. Further, the knob portion 15a is rotatable in addition to being switched between the normal position and the pushing position as described above, and is heated by adjusting the combustion by rotating it in the pushing position in an ignited state. It functions as a stove heating amount adjusting operation unit for adjusting the amount.

  As for the grill 13 operation section, the grill ignition / extinguishing operation section and the grill heating amount adjustment operation section are configured by a knob section 16 a similar to the knob section 15 a of the stove operation section 15.

  Next, the control unit 5 for controlling the gas flow and combustion will be described based on the schematic configuration diagram shown in FIG. The gas stove 12 and the grill 13 have the same basic gas flow and combustion. Therefore, the description of the grill 13 is omitted, and the gas stove 12 will be described.

  Each gas burner 2 is provided with a spark plug 23, a temperature detecting means 24 comprising a thermocouple for detecting whether or not the burner is burning, and the temperature sensor 3, which are connected to the control unit 5. It is.

  Each gas burner 2 is connected to a branch supply path 62 that branches from a fuel supply path 6 that supplies a gas fuel such as city gas. An original gas valve 61 is provided in the fuel supply path 6, and an electromagnetic on-off valve 63 that switches between supply and stop of gas fuel and adjustment of the supply amount of gas fuel are performed in each branch supply path 62. Therefore, a flow control valve 64 driven by a stepping motor capable of fine adjustment of the stop angle is provided. The on-off valve 63 and the flow rate control valve 64 are connected to the control unit 5, and operate according to a command from the control unit 5.

  When an ignition command is sent from the stove ignition / fire extinguishing operation unit or the grill ignition / fire extinguishing operation unit, the control unit 5 opens the on-off valve 63 and activates the spark plug 23 to detect the combustion state by the thermocouple. Then, the operation of the spark plug 23 is stopped and the ignition process is terminated. Then, the heating amount is adjusted based on the combustion amount command sent from the stove heating amount adjusting operation unit. When a fire extinguishing command is sent, the on-off valve 63 is closed and the gas burner 2 is extinguished.

  The controller 5 is capable of various cooking modes in which cooking is performed automatically. The cooking mode is performed by adjusting the amount of heating based on the temperature measured by the temperature sensor 3.

  The gas cooker 1 as described above has a gas cooker 1 up to a temperature that does not cause burn even after cleaning, that is, after manual cooking or cooking mode is finished and the heating means stops heating, and cleaning by wiping is performed. Is provided with a notification means for notifying that the temperature can be maintained when the temperature is reduced to a temperature that does not cause burns, and the control unit 5 has a function of the notification means. To perform these controls.

  The notification means starts the maintenance determination mode when the heating means is activated and the temperature measured by the temperature sensor 3 is equal to or higher than a certain temperature. In the care determination mode, when the cooking mode ends and heating by the heating means stops, and the temperature measured by the temperature sensor 3 of the temperature measuring means falls to a predetermined temperature, the temperature of the gas cooker 1 is suitable for care. Judging that the temperature has dropped to a temperature, it is determined that the temperature is suitable for cleaning. In this case, a correlation between the temperature measured by the temperature sensor 3 after stopping the heating means that has been operating and the temperature of the gas cooker 1 is obtained in advance, and the correlation between the gas cooker 1 and the correlation is obtained. The temperature of the temperature sensor 3 when the temperature becomes a temperature suitable for care is set as a predetermined temperature of the temperature sensor that determines that the temperature is suitable for care in the care determination mode. Here, the temperature of the gas cooker is different for each part, for example, the temperature of a plurality of parts such as the temperature of the top plate 11, the temperature of the virtues 14, and the temperature of the gas burner 2, and each part is suitable for maintenance separately. The temperature is determined and the notification is made. Below, the example which took the temperature of the top plate 11 as the temperature of the gas cooker 1 is demonstrated.

  FIG. 3 is a diagram showing, in time series, the temperature measured by the temperature sensor 3 and the temperature of the top plate 11 measured by another temperature sensor after heating by the heating means is stopped. Here, the temperature shown in the figure is the temperature of the top plate 11 when the container on the virtues 14 is moved to another place and the measured temperature of the temperature sensor 3 while stopping the heating by the heating means at the peak of the temperature sensor 3. In short, the temperature sensor 3 measures the temperature of the atmosphere.

  The temperature at which cleaning is easily performed should be about 50 ° C. or less (preferably 40 ° C. or less) that does not cause burns even with a slight touch. From this viewpoint, the lower the temperature, the more likely the burns are. However, the higher the temperature is, the softer the dirt becomes and the easier it is to remove, and the shorter the time required for the temperature to decrease, the higher the temperature is set to 40 ° C., which is as high as possible.

  In FIG. 3, the measured temperature of the temperature sensor 3 when the temperature of the top plate 11 reaches 40 ° C. is about 49 ° C. Therefore, when the temperature of the temperature sensor 3 reaches 49 ° C., the temperature of the top plate 11 is maintained. It is determined that the temperature is suitable for the temperature (that is, 40 ° C.).

  When the determination is made, the notifying means notifies that the temperature of the top plate 11 has reached a temperature suitable for cleaning. As the notifying means, for example, “Cleaning of the top plate (Gotoku, gas burner) is possible. There are various things such as those that make a voice announcement "can be done", those that are notified by other voices, those that are notified by light emission, and so on.

  And also about the temperature of other site | parts, such as the temperature of Gotoku 14, and the temperature of the gas burner 2, the correlation of the actual temperature of each site | part and the measured temperature of the temperature sensor 3 is calculated | required, and it carries out similarly to the case of the top plate 11, respectively. Is.

  According to the configuration as described above, the user can know that the temperature is suitable for cleaning, and the user will be burned by performing maintenance in a state where the temperature has not been sufficiently lowered. This can be prevented.

  In addition, by notifying each part such as the top plate 11, the virtues 14 and the gas burner 2, it is notified that the temperature has become suitable for care for each part where the rate of temperature decrease is not the same, and each part has an optimum temperature. In addition, it is possible to carry out the cleaning in order from the region where the temperature is suitable for the cleaning, and it is possible to shorten the time when all the cleaning is completed.

  In addition, it may be possible to select whether to notify each part. The selection is performed by operating the operation unit to send a command to the notifying unit of the control unit 5 and is preferably before cooking (that is, before manually operating the heating unit or before executing the cooking mode). It may be selectable during (that is, during operation of the heating means or during execution of the cooking mode) or after cooking (that is, after the start of the maintenance determination mode). Thereby, when only a specific part is cared for, there is no notification of other parts and it is not confusing.

  In addition to the gas cooker, the cooking device includes a so-called IH electromagnetic cooker that heats the container by induction heating.

  Further, the notification means is not limited to notification by voice, and it is needless to say that notification by display using an LED, a liquid crystal, or the like may be used.

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 a correlation diagram of the temperature measured by the temperature sensor and the actual temperature of the top board.
