Next, operation | movement of the cap 32 installed on the cover 29 of the drain tray 5 in this embodiment is demonstrated based on FIG.4 and FIG.5.
First, when the drain tray 5 is slid horizontally to the back side of the tray storage chamber 38 for storage in the tray storage chamber 38, the contact portion 36 contacts the pressing surface 41 and is pressed vertically downward. The arm 34 on the lid 35 side is moved upward to gradually open the opening 30, and the drainage tray 5 is slid horizontally to a position where the tray convex portion 39 gets over the mounting convex portion 40. When the storage is completed, the arm 34 is held in a state where the lid portion 35 is raised to the position where the opening 30 is completely opened, so that drainage dripping from the drain pipe 25 can flow into the drain tray 5 from the opening 30. It becomes a state.

  Then, after the mist operation is completed, a water draining operation is performed to drop the water in the water storage chamber 8 into the drain tray 5 through the drain pipe 25, and the water draining operation in the water storage chamber 8 is completed. When the three-way valve 22 is switched so as not to communicate with each other, when the handle of the drainage tray 5 is grasped and slid horizontally to the front side of the tray storage chamber 38 and the removal of the drainage tray 5 is started, the contact portion 36 is pressed against the pressing surface 41. If the drainage tray 5 is removed to a position where it does not come into contact with the arm, the force that presses the abutting portion 36 downward in the vertical direction disappears. Therefore, the arm 34 on the abutting portion 36 side is biased upward by the spring 37 and Since the opening 30 is closed by the downward movement of the arm 34, the opening 30 is completely closed by the lid 35 when the removal of the drainage tray 5 from the tray storage chamber 38 is completed.

Since the arm 34 on the side of the lid 35 moves upward and is held in the state where the opening 30 is opened by being pressed vertically downward, the storage of the drain tray 5 in the tray storage chamber 38 is completed. Then, drainage dripped from the drainage pipe 25 can flow into the drainage tray 5 from the opening 30, and when the drainage tray 5 is removed from the tray storage chamber 38, the arm 34 on the contact portion 36 side is urged vertically upward by the spring 37. As a result, the arm 34 on the side of the lid 35 moves downward and closes the opening 30, so when draining the wastewater, the drainage tray 5 is removed from the tray storage chamber 38 and transported to a washroom or the like. , It is possible to prevent the water leakage is generated from the draining tray 5.

  Further, when the drainage tray 5 is completely stored in the tray storage chamber 38, the tray convex portion 39 is locked at the position over the mounting convex portion 40, so that the abutting portion 36 of the cap 32 is pressed by the pressing surface 41. Since the drain tray 5 is firmly fixed in the tray storage chamber 38 in combination with being pressed downward vertically, the instrument body 1 is transported while the drain tray 5 is stored in the tray storage chamber 38. Even if the instrument body 1 is transported with the side surface on which the tray storage chamber 38 is formed being vertically downward, the drainage tray 5 does not jump out of the instrument body 1 and the instrument body 1 can be transported safely.

  In addition, since the contact portion 36 is formed so that the surface that protrudes toward the pressing surface 41 is curved, the contact portion 36 is pressed against the pressing surface 41 when the drain tray 5 is stored in or removed from the tray storage chamber 38. Since it can be smoothly slid without being caught on the surface, usability is improved.

  In the present embodiment, the shaft 33 is provided with the spring 37, and the arm 32 can be operated. However, the present invention is not limited to this. For example, the material and size of the lid 35 are changed. For example, a cap 32 having a structure in which the lid portion 35 is heavier than the abutment portion 36 may be used. When the drain tray 5 is removed from the tray storage chamber 38, the lid 35 is lowered by its own weight. When the opening 30 is closed and the drain tray 5 is stored in the tray storage chamber 38, the contact portion 36 contacts the pressing surface 41 and is pressed downward vertically, so that the lid portion 35 is upward. The structure which can be made to flow in into the drainage tray 5 from the opening 30 by operating and opening the opening 30 may be used.

  In the present embodiment, the upper surface side is described as the semicircular contact portion 36. However, the present invention is not limited to this, and for example, the contact portion 36 may be formed in a spherical shape, and the surface contacting the pressing surface 41 is a curved surface. Any other shape can be used.

  Further, the shape of the drainage tray 5 and the cap 32 used in the description of the present embodiment is an example, and changes depending on the position of the tray storage chamber 38 depending on the shape of the instrument body 1. Each numerical value can be changed.
