Among this type of heat cooker, a heat cooker with a cleaning function that automatically cleans the inside of the cooking chamber has also been developed. In a heating cooker with a washing function, washing water containing a strong alkaline detergent is sprayed into the cooking chamber in order to remove oil stains adhering to the inside of the cooking chamber. Washing water containing a strong alkaline detergent is sprayed not only on the peripheral wall of the cooking chamber, but also on the back side of the inner glass that faces the cooking chamber, and the washing water runs down the back side of the inner glass that faces the cooking chamber. At this time, a small amount of washing water that leaks from between the cooking chamber side of the inner glass and the packing may remain on the lower edge of the inner glass, and the washing water remaining on the lower edge of the inner glass will flow through the inner glass due to capillary action. The strong alkaline detergent contained in the washing water deteriorates the adhesive that has entered between the lower plates of the support bracket and adheres the inner glass to the lower plate, causing the inner glass to peel off and fall from the lower plate of the support bracket. there was a risk of In addition, when the door is opened and a strong alkaline detergent is sprayed directly on the inside of the cooking chamber and the inner glass, the detergent runs down the inner glass, and the detergent accumulated on the lower edge of the inner glass is caused by capillary action to flow under the inner glass and the support bracket. There is a risk that the adhesive that adheres the inner glass to the lower plate may be further deteriorated by the highly concentrated strong alkaline detergent. An object of the present invention is to prevent an inner glass from falling from a support bracket due to the influence of detergent contained in washing water for washing the inside of a cooking chamber.

In order to solve the above-mentioned problems, the present invention provides a cooking chamber having an opening through which foodstuffs are put in and taken out on the front surface within a housing, and a cooking chamber which is rotatably supported by the housing and closes the opening of the cooking chamber so as to be openable and closable. a door, the door being rotatably supported by a housing; an inner glass provided on the cooking chamber side of the door body; and a support bracket for supporting the inner glass on the door body. The support bracket has a lower plate portion that extends in the left-right direction at the lower portion of the front surface opposite to the cooking chamber side of the inner glass and is fixed by adhesion, and the lower edge of the lower plate portion is attached to the lower edge of the inner glass.

Even if the adhesive that adheres to the plate deteriorates and the inner glass is about to come off from the lower plate, the lower part of the inner glass is still in contact with the lower plate that is arranged on the front surface opposite to the cooking chamber side. Since the inner glass is sandwiched by the arms extending to the lower edge of the rear surface, it is possible to prevent the inner glass from falling. In addition, cleaning water containing detergent staying at the lower edge of the inner glass is less likely to reach the lower plate, and cleaning water is less likely to enter between the inner glass and the lower plate due to capillary action.

In the heating cooker configured as described above, the lower plate portion is fixed to the inner glass by bonding with the adhesive provided in a belt shape with the left-right direction of the inner glass as the longitudinal direction, and the adhesive is vertically spaced apart. It is preferable to provide at least one stage. In this way, when cleaning water containing detergent enters between the lower part of the inner glass and the lower plate part due to capillary action, the entering cleaning water reaches the lowermost adhesive and Even if the adhesive on the inner glass is degraded, it will not reach the adhesive on the upper side, so the inner glass will remain attached to the lower plate by the adhesive above the lowermost adhesive. It was possible to make it difficult for the glass to separate from the lower plate portion.

In the heating cooker configured as described above, it is preferable to form a gap between the corner portion between the lower surface of the inner glass and the front surface opposite to the cooking chamber side and the arm portion. When this is done, the cleaning water containing the detergent remaining on the lower edge of the inner glass tends to remain in the gap between the arms and the cleaning water flows from the corners of the lower surface of the inner glass and the arms by capillary action. It became difficult to go up to the lower plate part.

The air in the cooking chamber 20 is circulated as hot air by the operation of the heater 25 and the convection fan 26, and the circulating hot air includes the steam supplied from the steam generator 40. The accommodated foodstuffs are heated and cooked by hot air containing steam. When the food stored in the cooking chamber 20 is heated and cooked by hot air, the oil contained in the food is scattered by the hot air convection in the cooking chamber 20, and the scattered oil not only spreads over the peripheral wall of the cooking chamber 20 but also the opening 20a. It also adheres to the rear surface of the inner glass 32 of the cover door 30 on the cooking chamber 20 side.

When cleaning the interior of the cooking chamber 20 to which food oil adheres, a strong alkaline detergent is placed on a drain perforated plate 20d provided at the drain port 20c of the cooking chamber 20, and a cleaning program is executed. The washing program executes a washing mode for washing with washing water containing detergent and a three-time rinsing mode for washing with washing water containing no detergent. When the cleaning mode is started, the drain valve 16 is closed and the water supply valve 54 is opened for a predetermined time, so that cleaning water can be stored in the drain tank 13 . When the washing water is stored in the drain tank 13, the steam generator 40 is operated to supply steam into the cooking chamber 20, so that oil and the like adhering to the peripheral wall of the cooking chamber 20 is removed. It is preferable to allow the dirt to float.

When the pump 52 is operated after the wash water is stored in the drain tank 13 , the wash water stored in the drain tank 13 is sent to the wash nozzle 50 through the wash water supply pipe 51 . Washing water is sprayed from the washing nozzles 50 into the cooking chamber 20 over a wide range, and flows down from the ceiling wall of the cooking chamber 20 along the peripheral wall and the back surface of the inner glass 32 . The wash water flowing down the peripheral wall of the cooking chamber 20 returns to the drain tank 13 again through the first drain pipe 14 from the drain port 20c. The washing water returned to the drain tank 13 is sent to the washing nozzle 50 again by the pump 52, and the washing water circulates between the cooking chamber 20 and the drain tank 13. - 特許庁At this time, the solid detergent placed on the drain perforated plate 20d is gradually dissolved in the wash water flowing through the drain port 20c, and the wash water comes to contain the detergent.

Also, when the cleaning program is being executed, the heater 25 and the convection fan 26 are operated. The washing water spouted from the washing nozzle 50 is further sprayed to every corner of the peripheral wall of the cooking chamber 20 and the rear surface of the inner glass 32 by air convected by the convection fan 26 . In addition, since the heater 25 is also operated together with the operation of the convection fan 26, the air convecting in the cooking chamber 20 is heated, and the heated air is washed with the washing water sprayed into the cooking chamber 20 from the washing nozzles 50. It becomes warm. By activating the heater 25 and the convection fan 26 while the cleaning program is being executed in this way, the cleaning water jetted from the cleaning nozzle 50 reaches a high temperature state that facilitates removal of oil stains. The peripheral wall of the cooking chamber 20, the rear surface of the inner glass 32, the partition plate 23, and the support frame 24 are all sprayed with oil stains on the peripheral wall of the cooking chamber 20 and the like. When the washing mode of the washing program is executed for a predetermined period of time, the heater 25, the convection fan 26 and the pump 52 are stopped and the drain valve 16 is opened to drain the cleaning water containing detergent in the drain tank 13.

When the cleaning mode of the cleaning program ends, the rinse mode is executed. In the rinsing mode, the drain valve 16 is closed and the water supply valve 54 is opened for a predetermined time so that the drain tank 13 is filled with washing water for rinsing. After that, when the pump 52 is operated, the washing water stored in the drain tank 13 is sent to the washing nozzle 50 through the washing water supply pipe 51, and is ejected from the washing nozzle 50 in the same manner as in the washing mode described above. Washing water is sprayed to every corner of the peripheral wall of the cooking chamber 20, the rear surface of the inner glass 32, the partition plate 23 and the support frame 24, and the washing water containing the detergent sprayed in the washing mode is washed away. can be done. Also in this rinsing mode, the heater 25 and the convection fan 26 are operated, and the convection fan 26 is alternately rotated in the normal direction and the reverse direction. When the rinsing mode of the washing program is executed for a predetermined time, the heater 25, the convection fan 26 and the pump 52 are stopped, the drain valve 16 is opened and the washing water used for rinsing in the drain tank 13 is drained. In addition, in this embodiment, the washing program is completed by executing the rinsing mode three times as a plurality of times.

When the cleaning program for cleaning the inside of the cooking chamber 20 is executed, the cleaning water sprayed onto the inner glass 32 and containing the detergent flows down along the inner glass 32 . The washing water that has flowed down leaks slightly from between the back surface of the inner glass 32 on the side of the cooking chamber 20 and the packing 11a, and the washing water containing detergent may remain on the lower edge of the inner glass 32. - 特許庁The cleaning water remaining on the lower edge of the inner glass 32 enters between the inner glass 32 and the lower plate portion 35 of the support bracket 33 by capillary action, and the adhesive 35a that adheres the inner glass 32 to the lower plate portion 35 is washed. There was a risk of deterioration due to the detergent contained in the water.

As a result, washing water containing detergent enters between the inner glass 32 and the lower plate portion 35, and the detergent contained in the washing water deteriorates the adhesive 35a that bonds the inner glass 32 to the lower plate portion 35. Therefore, even if the inner glass 32 is about to come off from the lower plate portion 35, the lower portion of the inner glass 32 is separated from the lower plate portion 35 arranged on the front surface opposite to the cooking chamber 20 side and the lower edge of the back surface facing the cooking chamber 20 side. Since the inner glass 32 is sandwiched by the arm portion 35c extending to the side of the cooking chamber 20, the inner glass 32 can be prevented from falling from the support bracket 33.例文帳に追加

Further, in the door 30 of the heating cooker 10 , the lower edge of the lower plate portion 35 of the support bracket 33 is arranged at a position higher than the lower edge of the inner glass 32 . As a result, the cleaning water remaining on the lower edge of the inner glass 32 is less likely to reach the lower plate portion 35, and the cleaning water is less likely to enter between the inner glass 32 and the lower plate portion 35 due to capillary action. .

Further, in the door 30 of the heating cooker 10, the lower plate portion 35 is fixed to the inner glass 32 by bonding with an adhesive 35a provided in a belt shape with the lateral direction of the inner glass 32 as a longitudinal direction, and the adhesive 35a is separated vertically. are provided in two stages (two or more stages). By doing so, when washing water enters between the lower portion of the inner glass 32 and the lower plate portion 35 by capillary action from below, the entering washing water reaches the lowermost adhesive 35a. Even if the lowermost adhesive 35a is degraded, it is difficult to reach the upper adhesive 35a. The state of being adhered to the portion 35 was maintained, and the inner glass 32 could be made difficult to separate from the lower plate portion 35 . In this embodiment, the adhesive 35a for adhering the inner glass 32 to the lower plate portion 35 is provided in two stages above and below. may be Also, although the effect described in this paragraph cannot be obtained, other effects can be obtained if the adhesive 35a is one step.

Further, in the door 30 of the heating cooker 10, a gap is formed between the corner portion between the lower surface of the inner glass 32 and the front surface opposite to the cooking chamber 20 side and the right arm portion 35c. Specifically, a curved surface portion 32a having a curved surface shape called a radius is formed at a corner portion between the lower surface of the inner glass 32 and the front surface opposite to the cooking chamber 20 side. A gap is formed between it and the arm portion 35c bent at right angles. This gap makes it difficult for the wash water remaining on the lower surface of the inner glass 32 to rise to the lower plate portion 35 due to capillary action from the corners between the lower surface and the front surface of the inner glass 32 and the arm portion 35c.
