Description

  The present invention relates to a heating chamber built in a heating cooker used in general households.

  Conventionally, this type of heating chamber is provided with a catalyst at the exhaust port in order to remove smoke emitted from the heated object heated in the heating chamber. This catalyst exhibits the effect of smoke removal by being heated. For that purpose, a heater for heating the catalyst is provided, or a heater for heating an object to be heated is used in combination with heating of the catalyst. I'm taking it.

  Moreover, there exists what devised the shape of a heater (for example, refer patent document 1).

  FIG. 8 is a perspective view of a conventional heating chamber, and FIG. 9 is an exploded perspective view thereof. As shown in FIG. 8, an upper heater 20 and a lower heater 21 for heating the object to be heated are provided in the heating chamber 19, and an exhaust for exhausting smoke emitted from the object to be heated is provided above the heating chamber 19. A mouth 22 is provided. A catalyst 23 is provided at the exhaust port 24, and smoke emitted from the object to be heated passes through the catalyst 23 and is exhausted.

10 and 11 show a sectional view of a conventional heating cabinet 19 and an upper heater 20. The upper heater 20 heats the article to be heated from above and simultaneously heats the catalyst 23 disposed above. As shown in FIG. 10, the upper heater 20 is provided with a curved portion 24 at the front center portion, and the curved portion 24 is arranged so as to cross under the catalyst 23 as shown in FIG. 11.

  However, in the conventional configuration, since the catalyst is not sufficiently heated, it is difficult to sufficiently remove smoke emitted from the cooked product. Further, if the amount of heat generated by the heater is increased and the temperature of the catalyst is set to an appropriate temperature in order to sufficiently heat the catalyst, there is a problem that the temperature of the heated object below the catalyst is excessively increased.

  Accordingly, an object of the present invention is to set the temperature of the catalyst to an appropriate temperature and to prevent the temperature of the heated object below the catalyst from excessively rising.

  In order to solve the above-mentioned conventional problems, in the heating chamber of the present invention, the upper heater has a curved portion bent so as to bend from the rear to the front below the catalyst, and surrounds the curved portion around the approximate center of the catalyst. It is formed as follows.

  As a result, a curved portion bent so as to bend from the rear below the catalyst is formed so as to surround substantially the center of the catalyst and heats the catalyst, so that the heat generated by the upper heater is efficient for the entire catalyst. If the temperature of the catalyst is too low, or if the heating value of the heater is increased and the temperature of the catalyst is set to an appropriate temperature, the temperature of the heated object under the catalyst will not rise too much. Usability can be improved.

  The heating chamber of the present invention improves the smoke removal effect by simultaneously and efficiently heating the catalyst with the upper heater that heats the object to be heated, and also improves the uneven baking of the object to be heated in the chamber by the upper heater. The usability can be improved.

  1st invention arrange | positions in the upper part in a store | warehouse | chamber, the upper heater which heats to-be-heated material from the upper part, the top | upper surface opening part for exhausting the smoke in the store | warehouse | chamber provided in the upper surface of a heating store | warehouse | chamber, An exhaust port for exhausting to the outside, and a planar catalyst provided near the top surface opening portion for removing smoke from the interior to the exhaust port, and the upper heater is located below the catalyst A first bending portion bent so as to be bent from the rear to the front is formed, and the first bending portion is formed so as to surround a substantially center of the catalyst and is a heating chamber formed by heating the catalyst. Thus, the first curved portion bent so as to bend from the rear below the catalyst is formed so as to surround the approximate center of the catalyst and heats the catalyst, so that the heat generated by the upper heater is transferred to the entire catalyst. It is transmitted efficiently and the temperature of the catalyst becomes too low, or conversely, the heater generates heat When the proper temperature the temperature of the catalyst increases, it is possible that the temperature of the heated object of the catalyst downward improve usability as there is no disadvantage that excessively increase.

  In the second aspect of the invention, in particular, the upper heater has only the first curved portion disposed below the catalyst and curved so as to raise the temperature of the catalyst to the extent that the smoke removal function is exhibited. Therefore, the other part of the heater can be provided at a location where the temperature distribution in the cabinet is low, the temperature of the portion in the cabinet where the temperature tends to be low can be increased, and the uneven baking in the cabinet can be improved. .

  According to a third aspect of the invention, in particular, the upper heater has a second curved portion bent from the front to the rear, and the second curved portion is arranged in front of the catalyst, so that the door in the warehouse is provided. It is possible to increase the temperature of the portion where the temperature tends to be low, and to improve uneven baking in the cabinet.

  In the fourth aspect of the invention, in particular, since the bending radius of the second bending portion is made larger than the bending radius of the first bending portion, the temperature close to the door is suppressed while suppressing the rear temperature from becoming too high. It is possible to increase the temperature of the portion that tends to be low, and to improve uneven baking in the cabinet.

  In particular, the fifth invention includes a lower heater for heating the object to be heated from below, and the curved portion formed in the lower heater is in the left-right direction, so that the temperature distribution in the entire interior is more uniform. Can improve usability.
