However, it takes a considerable time for the heater to cool. Therefore, it is not possible to respond to the request to quickly remove the heater and wash it. Therefore, in the third embodiment, a case will be described in which the heater is quickly cooled so as to meet such a requirement, thereby ensuring safety early.
FIG. 4 is a side sectional view showing Embodiment 3 of the built-in heating cooker according to the present invention, and shows only the main part. 4, the same reference numerals as those in FIGS. 1 to 3 denote the same parts or corresponding parts. Except for the addition of a heater opening 135 and an opening / closing lid 136, the configuration is substantially the same as that of FIG. In FIG. 4, an exhaust path is shown, but this is not shown in Embodiments 1 and 2, and is similarly provided.
As shown in FIG. 4, the heater opening 135 is provided on the front side of the upper heater 132a and in the upper part of the front surface of the housing 112. The opening / closing lid 136 is provided behind the heater opening 135 and can be opened / closed by moving substantially vertically, and is opened / closed by a signal from the control unit 140. Further, an exhaust duct 137 communicating with the exhaust port 121 formed in the top plate 120 is provided on the back surface of the grill cabinet 130, and an exhaust fan 138 is installed in the exhaust duct 137. The exhaust fan 138 discharges hot air in the grill 130 by rotation, and has a variable rotation frequency. The rotation frequency is controlled by a driving unit (not shown) based on a command from the control unit 140. .

Next, the operation of the third embodiment will be described.
At the beginning of cooking, the heater 132 is energized by a signal from the control unit 140 to heat the object to be heated. However, after the cooking is completed, the energized heater 132 may be quickly removed and washed. is there. Therefore, in order to meet such a requirement, the heater temperature after heating should be lowered as soon as possible from the viewpoint of safety (burn).
As the energization of the heater 132 ends, the control unit 140 controls the moving drive means (not shown) so that the opening / closing lid 136 disposed in front of the heater 132 is opened. As a result, the opening / closing lid 136 is automatically opened, so that even when the grill door 131 is housed, the heater opening 135 provided in the front surface of the heating cooker body 110 and the inside of the grill cabinet 130 are Communication is made via an open / close lid 136.

Thereby, the temperature of the heater 132 can be rapidly lowered at the end of cooking.

Embodiment 4 FIG.
In the first to third embodiments, the alarm output destination is voice or display. In the fourth embodiment, means for informing the user by a method other than voice and display will be described. Specifically, a description will be given of means for allowing the skin to feel that the hand is still hot and dangerous when the hand is inserted into the grill 130. In the present embodiment, it is assumed that the outside air temperature is lower than the body temperature.
FIG. 3 is also used in this embodiment.
FIG. 5 is a side sectional view showing Embodiment 4 of the built-in heating cooker according to the present invention. 5, the same reference numerals as those in FIGS. 1 to 4 denote the same or corresponding parts. As shown in FIG. 5, an air temperature adjustment chamber 139 provided near the exhaust port (ie, near the entrance of the exhaust duct) formed on the back surface of the grill cabinet 130, and the temperature is detected in the air temperature adjustment chamber 139. The temperature detection means 1391, the outside air fan 1392, the opening / closing means 1393, one end is connected to the outlet of the air conditioning chamber 139, and the other end passes through a hole formed in the lower part of the back wall of the grill cabinet 130. 4 except that a duct 1394 opened in the vicinity of the grill door 131 in the grill cabinet 130 is added. The rotation frequency of the outside air fan 1392 is variable, and the rotation frequency is controlled by the driving unit based on a command from the control unit 140.

  During cooking, the operation is the same as in the third embodiment. When cooking is finished and the user pulls out the grill door 131 for maintenance such as cleaning, an electrical signal is sent from the door detection means 1312 shown in FIG. When the control unit 140 detects this by a signal from the door detection unit 1312, the controller 140 drives the opening / closing unit 1393 of the air temperature adjustment chamber 139 to open at a predetermined opening and drives the outside air fan 1392 to remove the outside air from the air temperature adjustment chamber. The heat is exchanged with the exhaust gas that is taken into the exhaust gas 139 and passes through the exhaust duct 137. In this case, the outside air may be configured to enter through a gap in the housing, or an outside air inlet may be provided on the side wall of the housing. Further, the control unit 140 examines the temperature of the heater 132 detected by the heater temperature detection unit 180 and compares it with a first reference temperature set in advance. As a result of the comparison, if it is determined that the temperature is equal to or higher than the first reference temperature and is dangerous to cause burns when touched, the control unit 140 detects the temperature in the air temperature adjustment chamber 139 detected by the temperature detection unit 1391. The opening degree of the opening / closing means 1393 and the rotation frequency of the outside air fan 1392 are controlled so that this temperature is relatively high (for example, about 40 ° C.) within a safe range, and then the duct 1394 is connected from the outlet of the adjustment chamber 139. The air is blown out from the vicinity of the grill door 131 in the grill cabinet 130.

  The direction from which the air is blown out from the air outlet is a direction in which the hand or finger of the user can easily hit. Thereby, before the user opens the grill door 131 and touches the heater 132, a safe and relatively hot wind hits the user's hand. Further, the blowing method may be performed intermittently or continuously. Further, as a result of the comparison, the temperature of the heater 132 is equal to or lower than the first reference temperature, and is compared with a second reference temperature lower than the first reference temperature. As a result of the comparison, if the temperature is lower than the second reference temperature, the control unit 140 determines that the temperature of the heater 132 has surely decreased to a safe temperature range, fully opens the opening / closing means 1393, and sucks outside air. By controlling the rotation frequency of the outside air fan 1392 so as to reach a predetermined temperature (for example, about 25 to 30 ° C.) lower than the body temperature by maximizing the amount and controlling the rotation frequency of the outside air fan, It blows out from the vicinity of the grill door 131 in the grill cabinet 130 through the duct 1394 from the outlet. It may be configured so that the outside air directly hits the user's hand without heat exchange. In this case, there is a temperature difference between the safe and relatively high temperature wind and the cold air temperature between the body temperature and the outside air. Since it enlarges, it becomes easier for the user who feels it with skin to touch the heater 132 to determine whether or not it is dangerous.

  With the above configuration, if the user knows the above in advance, the temperature of this wind is examined with the skin before touching the heater 132 when the user tries to operate the inside of the grill 130. When a safe and relatively hot wind or a safe wind lower than the body temperature hits the hand or finger, the user can feel that the heater 132 is hot and dangerous, and can grasp the hand with his hand. Close the door 131 and wait. As a result, the user is not burned. Thereafter, after a time when the heater is considered to be in a sufficiently safe temperature range, the user opens the grill door 131 again and re-operates the inside of the grill cabinet 130. When touched by a finger, the user can detect with the skin that the temperature of the heater 132 is within a safe temperature range, and can safely perform operations such as removal of the heater 132.

  The cooking device according to the present invention can be widely used in the industrial field in which a cooking device is manufactured, sold, and used.

An air temperature adjustment chamber provided near the exhaust port of the exhaust passage;
A duct having one end connected to the outlet of the air temperature adjustment chamber and the other end opened near the door in the grill cabinet;
The air temperature adjustment chamber includes an indoor temperature detecting means for detecting the temperature of the room, an outside air fan for sucking the outside air, and an opening / closing means for opening and closing an outside air entrance and exit.
When the control means detects the opening / closing operation of the door based on the output from the door opening / closing detection means after the energization of the heater is completed, the temperature of the heater detected by the heater temperature detection means is burned. When the temperature is equal to or higher than the first temperature, the outside air is sucked into the air temperature adjustment chamber by the exhaust fan to exchange heat with the flue gas passing through the exhaust path, The grill by controlling the opening degree of the opening and closing means and the rotational frequency of the exhaust fan so that the temperature of the outside air after the heat exchange detected by the temperature detecting means is a second temperature higher than the body temperature without being burned. A balloon in the cabinet,
When the temperature of the heater detected by the heater temperature detecting means falls below the third temperature compared to a third temperature at which no burn is caused, the opening / closing means is fully opened and the indoor temperature 2. The blower is blown into the grill cabinet by controlling the rotation frequency of the exhaust fan so that the temperature of the outside air after the heat exchange detected by the detecting means becomes a fourth temperature lower than the body temperature. The heating cooker described in 1.
