However, the capacity of the water pan is limited. Therefore, if dew condensation water is further generated on the door while the dew condensation water is stored in the water pan, and the dew condensation water drips onto the water pan, the capacity of the water pan is exceeded and the dew condensation leaks from the water pan. there is a possibility.

The present disclosure has been made against the background of the above-mentioned problems, and provides a cooking device in which leakage of dew condensation water generated on the back surface of a front door is suppressed.

The heating cooker according to the present disclosure has a main body having a heating chamber for accommodating an object to be heated, and the heating object provided inside the main body below the heating chamber to heat the object to be heated contained in the heating chamber. It is arranged in front of the front opening formed at the front end in the heating chamber in order to put in and take out the heating means and the object to be heated, and is placed in the main body so that the front opening can be opened and closed. It comprises a rotatably supported door and a dew receiver provided below the front end of the body and configured to receive liquid dripping downward from the back surface of the door, at least of the dew receiver. A part of it is in contact with the bottom surface of the main body.

According to the present disclosure, at least a part of the dew receiver provided below the front end of the main body and configured to receive the liquid dripping downward from the back surface of the door is in contact with the bottom surface of the main body. Therefore, the heat generated during heating of the object to be heated is conducted to the dew receiver via the bottom surface of the main body and the portion of the dew receiver that is in contact with the bottom surface of the main body. Therefore, during heating of the object to be heated, evaporation in the receiving portion of the dew condensation water generated on the back surface of the door and dripping on the dew receiving portion is promoted. As a result, the phenomenon that the condensed water dropped on the dew pan leaks from the dew pan is suppressed.

As a result, it is suppressed that the condensed water leaks to the outside of the main body 10 of the cooking device 1.

In the first embodiment, the contact portion 41 of the dew receiver 40 is in contact with the lower case bottom surface 63 of the lower case 61 which constitutes the bottom surface of the main body 10 of the cooking cooker 1. Therefore, during the heating of the object to be heated, the heat generated by the lower heater 642A is conducted to the receiving portion 42 via the lower case bottom surface 63 and the contact portion 41. Therefore, during the heating of the object to be heated, the evaporation of the condensed water generated on the back surface of the door 20 and dripping on the dew receiving 40 in the receiving portion 42 is promoted. As a result, the phenomenon that the dew condensation water dropped on the dew receiver 40 is accumulated in the dew receiver 40 and leaks out is suppressed. That is, according to the first embodiment, the leakage of the dew condensation water generated on the back surface of the door 20 is suppressed.

Since the condensed water evaporates in the receiving portion 42, the accumulation of the condensed water in the dew receiving 40 is suppressed. Therefore, maintenance such as removing the stored matter from the dew receiver 40 becomes unnecessary, and the convenience is improved.

In order to prevent the condensed water from overflowing from the dew receiver 40, it is desirable to make the length of the wall portion 43 in the vertical direction longer. However, since the dew receiver 40 is attached to the bottom surface of the main body 10, if the length of the wall portion 43 in the vertical direction is increased, the portion protruding downward from the bottom surface of the main body 10 becomes large, and the design of the front view is deteriorated. .. According to the first embodiment, since the accumulation of the dew condensation water dripping on the dew receiver 40 is suppressed by the evaporation due to the heat conduction described above, the depth of the dew receiver 40 can be set shallow. That is, it is possible to prevent the wall portion 43 from becoming long in the vertical direction while improving the drainage property. Therefore, the deterioration of the design when the cooking device 1 is viewed from the front is suppressed. In particular, when the cooking cooker 1 is installed in the kitchen furniture 100, the gap L between the lower surface of the main body 10 and the kitchen furniture 100 shown in FIG. 6 can be made smaller, so that the cooking cooker 1 is installed in the kitchen furniture 100. It is possible to improve the design when the furniture is used.

In the first embodiment, by screwing the dew receiver 40 to the bottom of the main body 10, it is possible to ensure the contact of the contact portion 41 with the bottom of the main body 10. Therefore, the heat conduction to the dew receiver 40 of the lower heater 642A described above can be improved.

Further, in the first embodiment, since the dew receiver 40 is screwed from below the main body 10, the dew receiver 40 can be easily attached and detached from the outside of the main body 10. Therefore, the cleaning work of the dew receiver 40 is easy.

The unit 80 is cooled. A part of the air rising in the space 1A passes through the space 3A formed so as to extend in the left-right direction between the upper partition plate 643 and the heating chamber upper case 641C. The air that has passed through the space 3A flows toward the communication port 153 in the direction orthogonal to the paper surface of FIG. That is, as shown in FIG. 9, the air that has passed through the space 2A passes through the space 3A formed so as to extend in the front-rear direction between the upper partition plate 643 and the heating chamber upper case 641C. The air that has passed through the space 3A flows from the communication port 153 into the first duct horizontal portion 181A, is guided to the first duct horizontal portion 181A and the first duct vertical portion 181B, and is discharged from the first exhaust port 151. That is, the first exhaust path is configured such that the cooling air from the first cooling fan 111 that cools the microwave heating circuit 180 passes through the inside of the main body 10 and is discharged to the outside of the main body 10 by the first duct 181. It is an exhaust path.

The second exhaust path will be described with reference to FIGS. 8 to 10.
