Claims (4)

1. A stove burner burns a mixture of gas and air to form a flame, A sensor is provided on the stove burner, which contacts the bottom of a container supported by a trivet and detects the temperature of the bottom, A gas stove characterized by comprising: a display control unit that, after a predetermined waiting time has elapsed since the combustion of the stove burner stopped and the temperature of the portion in contact with the bottom of the sensor has been smoothed out , displays the smoothed estimated temperature of the heated object in the container, which is estimated based on the detection result of the sensor, on the display unit.
2. A setting unit for setting the set temperature of the object to be heated, A combustion stop unit that stops the combustion of the stove burner when the estimated temperature reaches a specified temperature higher than the set temperature after the combustion of the stove burner has started, After the combustion stop unit stops the combustion of the stove burner, a determination unit determines whether the estimated temperature has reached the set temperature, The gas stove according to claim 1, further comprising a determination unit and a notification unit that notifies when the determination unit determines that the estimated temperature has reached the set temperature.
3. The gas stove according to claim 1 or 2, characterized in that the waiting time is the time from when the combustion of the stove burner stops until heat transfer progresses in the container from the part heated by the flame of the stove burner to other parts.
4. A storage unit that stores time information indicating the relationship between the slope of the temperature change at the bottom detected by the sensor at the start of combustion of the stove burner and the waiting time, A calculation unit that calculates the slope of the temperature change at the bottom of the stove burner when combustion begins, The gas stove according to claim 1 or 2, further comprising a determination unit that determines the waiting time based on the slope of the temperature change at the bottom calculated by the calculation unit and the time information stored in the storage unit.

Description

This invention relates to a gas stove. Conventionally, a cooking appliance has been proposed that includes a burner, a temperature sensor that contacts the bottom surface of a container from below to detect the container's temperature, and a display unit. This appliance corrects the estimated temperature, which is based on the temperature sensor's reading, based on correction values corresponding to the container type, the amount of food being cooked, and the heating state by the burner, and displays the corrected temperature on the display unit (see, for example, Patent Document 1). Japanese Patent Application Publication No. 7-77330 This is a perspective view of gas stove 1.This is a front view of the left control panel 19.This graph shows the time-dependent changes in thermistor temperature and water temperature.This is a block diagram showing the electrical configuration of gas stove 1.This is a conceptual diagram of the waiting time table 20.This is a flowchart of the display control process.This is a flowchart showing the continuation of Figure 6. The embodiments of the present invention will be described below. The apparatus configurations and processes described below are merely illustrative examples and not intended to limit the invention unless otherwise specified. The drawings are used to illustrate the technical features that the present invention may employ. The following explanation will use the left/right, front/back, and up/down directions indicated by arrows in the drawings. Referring to Figure 1, the configuration of the gas stove 1 will be described. The gas stove 1 is a built-in stove and comprises a casing 2 and a top plate 3. The casing 2 has an opening at the top, and the top plate 3 is installed in the opening. On the top plate 3, a right burner 4 (hereinafter referred to as right burner 4) is provided on the front right, a left burner 5 (hereinafter referred to as left burner 5) is provided on the front left, and a rear burner 6 (hereinafter referred to as rear burner 6) is provided on the back center. Near the flame hole of the right burner 4, the ignition electrode of the igniter 4A and the thermocouple 4B (see Figure 3) are installed so as to face the flame hole. Near the flame hole of the left burner 5, the ignition electrode of the igniter 5A and the thermocouple 5B (see Figure 3) are installed so as to face the flame hole. Near the flame opening of the rear burner 6, the ignition electrode of the igniter 6A and the thermocouple 6B (see Figure 3) are installed so as to face the flame opening. Igniters 4A to 6A, when driven, generate a spark discharge at the ignition electrode, igniting the gas ejected from the flame hole. Thermocouples 4B to 6B are heated by the flame formed in the flame hole, generating a thermoelectric voltage. Based on the thermoelectric voltage generated in thermocouples 4B to 6B, the gas stove 1 can detect misfires in the right burner 4, left burner 5, and rear burner 6. Sensors 24, 25, and 26, projecting upwards, are provided approximately in the center of each of the right burner 4, left burner 5, and rear burner 6. Thermistors 4C, 5C, and 6C are housed inside each of the sensors 24, 25, and 26. Sensors 24, 25, and 26 are pressed down upon contact with the bottom of a container placed on the trivet. Thermistors 4C, 5C, and 6C detect the temperature of the bottom of the container via the contact points of sensors 24, 25, and 26. An exhaust vent 7 for the grill compartment (not shown) is provided at the rear of the top plate 3. A grill door 8 is provided approximately in the center of the front of the gas stove 1. The grill door 8 opens and closes the front opening of the grill compartment. Two operation buttons 11 and 12 are provided horizontally in the area to the right of the grill door 8. Two operation buttons 13 and 14 are provided horizontally in the area to the left of the grill door 8 at the same height as operation buttons 11 and 12. Each of the operation buttons 11 to 14 is operated to ignite, extinguish, and adjust the heat output of the right burner 4, the grill burner (not shown) in the grill compartment, the rear burner 6, and the left burner 5. Inside the housing 2, four fuel supply devices (not shown) corresponding to each of the operation buttons 11 to 14 are provided. The fuel supply devices supply gas to the corresponding right burner 4, grill burner, rear burner 6, and left burner 5 in conjunction with the operation of the corresponding operation buttons 11 to 14. Below operation buttons 11 and 12, panel 9A is provided, and below operation buttons 13 and 14, panel 9B is provided. When panel 9A is pressed with a finger, a well-known push-push mechanism (not shown) causes the right operation panel 18 (see Figure 4), fixed to the back of panel 9A, to rotate forward from its lower point and be pulled out. The right operation panel 18 is equipped with various buttons for operating the right burner 4 and the grill device, respectively, as wel
