  In such a cleaning machine, steam leaks from the space between the door portion and the main body to the outside of the cleaning chamber, and condensation occurs on the door portion and the main body near the portion where the steam touches the outside air. When the amount of dew condensation is large, water drops may fall on the floor and wet the floor.

  Accordingly, an object of the present invention is to provide a washing machine that can reduce the amount of steam leaking from the space between the door part and the main body part to the outside of the washing chamber and suppress the occurrence of condensation. .

  The cleaning machine according to the present invention has an opening through which a body portion in which an opening for taking in and out an object to be cleaned is opened forward and a rotating shaft is rotatably supported at a lower portion of the opening. A door portion that can be opened and closed, and has an extending portion that projects in the vertical direction at both ends in the direction in which the rotating shaft extends and protrudes toward the cleaning chamber when the door portion is closed. A door portion and an accommodating portion that is provided inside the side edge portion of the opening and that extends in the up-down direction that opens toward the front. The gap between the extension part and the storage part that entered the storage part from the front when the door part is closed forms a communication path that connects the inside and the outside of the cleaning chamber, and in a part of the communication path, A gap adjusting portion is formed that widens the gap in a stepwise or continuous manner from the upper side to the lower side in the vertical direction.

  In the washing machine having this configuration, the internal pressure in the washing chamber is suppressed from rising by forming a communication passage that allows steam to escape from the left and right ends of the door when the door is closed. And there exists a part formed so that the clearance gap between the extension part of the door part which forms a communicating path, and an accommodating part may become narrower toward the upper side in the up-down direction, and may become wide toward the lower side. Accordingly, it is possible to suppress the steam that generally flows upward in the cleaning chamber from leaking out of the cleaning chamber through the communication path. As a result, the amount of steam leaking from between the door portion and the main body portion to the outside of the cleaning chamber can be reduced, and the occurrence of condensation can be suppressed.

  In the cleaning machine of the present invention, the gap adjusting portion may be formed at an exit portion to the outside in the communication path.

  In the washing machine having this configuration, the outlet portion to the outside of the communication path is formed so as to be narrower toward the upper side in the vertical direction and wider toward the lower side, so that it is possible to prevent the steam from leaking to the outside. Thereby, generation | occurrence | production of dew condensation can be suppressed more reliably.

  In the cleaning machine of the present invention, the housing portion has a facing portion that faces the side wall of the cleaning chamber across the extending portion when the door portion is closed, and a connecting portion that connects the side wall and the facing portion. A gap filling member is disposed between the extended portion and the side wall so that the gap between the extended portion and the extended portion increases stepwise or continuously from the upper side to the lower side in the vertical direction. Thus, a gap adjusting portion may be formed.

  In the washing machine having this configuration, the accommodating portion of the extending portion when the door portion is closed can be easily formed. In addition, in the communication path serving as a path for steam, a configuration in which the gap is widened stepwise or continuously from the upper side to the lower side in the vertical direction can be easily realized.

  In the cleaning machine of the present invention, the gap filling member may have a gap holding portion arranged at a portion sandwiched between the side wall and the facing portion.

  In the cleaning machine having this configuration, the gap filling member is interposed in the space between the side wall and the facing portion, so that the strength of the facing portion can be reinforced. Thereby, even if a facing part is a member comparatively weak to a deformation | transformation formed by bending a plate-shaped member, it can suppress that the shape of a facing part deform | transforms.

  According to the present invention, the object of the present invention is to reduce the amount of steam that leaks from between the door portion and the main body portion to the outside of the cleaning chamber, thereby suppressing the occurrence of condensation.
