Description

Detailed Description of the Invention [Technical Field] The present invention relates to an air conditioner in which an air supply port is opened and closed by operating a control lever up and down. [Background Art 1] There is an air conditioner as shown in FIG. 6, which is built into a cabinet riser or the like to provide ventilation between the room and the floor space. This empty 5ets place has duct opening 13 at the bottom.
An air supply plate 2 is attached to the front opening of a box body 12 provided with an air supply plate 2, and an air supply port 1 formed on this air supply plate 2 is formed so that it can be opened and closed with a lid 6 by operating a four-operation lever 4. . That is, it was provided on the air supply plate 2. Attach the operating lever 4 through the fi hole 3, and as shown in FIG. I arrived at the pivot! !
A pivot 16 is provided protruding from the side surface of the operating lever 4, and this pivot 16 is slidably fitted into an idle hole 17 provided in the operating lever 4, and as shown in FIG. When the operating lever 4 is rotated so that the part protruding from the air plate 2 toward the surface side is directed upward, the probe 6 is rotated so as to fall down, and the air supply port 1 is opened. When the operating lever 4 is rotated so that the part of the operating lever 4 that protrudes from the air supply plate 2 toward the front side faces downward, l
I6 is rotated to stand up so that the air supply port 1 can be closed. However, in this case, when the lid 6 is rotated in the direction indicated by the arrow a in FIG. 7(b) due to its own weight, the operating lever 4 also protrudes from the air supply plate 2. The problem is that the part rotates in the direction of arrow b, making it impossible to keep the air supply port 1 closed with the lid 6, which may result in the air supply port 1 being opened inadvertently. was there. [Object of the Invention] The present invention has been made in view of the above points, and an object of the present invention is to provide an air conditioner that can keep the air supply port closed with a lid. . EDisclosure of the InventionJ The air conditioner according to the present invention has a working hole 3 formed in an air supply plate 2 provided with an air supply port 1, and a working lever 4 passed through the operating hole 3. The air supply port 1 is pivoted near the center of the air supply port 1 so that it can freely move up and down. A lid 6 for opening and closing is disposed on the back side of the air supply plate, and a holding means 7 for holding the rotational position of the operation lever 4 in a state in which the lid 6 is rotated so as to close the air supply port 1 is provided. %
It is characterized by being tilted downward, and is equipped with a holding means 7 for maintaining the rotational position of the operating lever 4 in a state in which the lid 6 is rotated so as to close the air supply port 1. The above object has been achieved, and the present invention will be explained in detail below with reference to Examples. The air supply plate 2, which is attached to the front opening of the box body 12 of the air conditioner with screws 18, has a horizontally long air supply port 1 as shown in Figure @1. is provided with an operation hole 3. The operation hole 3 is formed in the shape of a vertically long slit, and a locking convex step 8 is formed to protrude from the upper part of one inner edge. An operating lever 4 is passed through the operating hole 3, and as shown in FIG.
An id elongated hole 17 is formed at the tip. A bearing protruding from the rear side of the end of the air supply plate 2 is provided with a shaft 14 on the plate 19, and approximately the center of the working lever 4 is pivoted to this shaft 14 to move the working lever 4 up and down. It is rotatable. Also'M
6 has its lower end pivotally connected to the air supply plate 2 by a hinge 15, and is arranged on the back side of the air supply plate 2 so as to be able to move up and down.
By rotating and standing vertically, the air supply port 1 is blocked, and by rotating and knocking down the strainer 6, the air supply port 1 is closed.
It is designed so that it can be opened. ii6 f
A side plate 20 is provided at the il end, and a pivot 16 protruding from this side plate 20 is inserted into an elongated hole 17. When the operating lever 4 is rotated so that the part of the operating lever 4 that protrudes from the air supply plate 2 to the front side faces upward as shown in FIG. The lid 6 is rotated so as to fall down by being slid inside the lid, and the air supply port 1 can be opened. At this time, the operating lever 4 is located above the operating hole 3 as shown in FIG. 3(a). next! @2 When the operating lever 4 is rotated so that the part of the operating lever 4 that protrudes from the air supply plate 2 to the front side faces downward as shown in Fig. 2 (b), the pivot 16 slides inside the idle slot 17. The M6 rotates as if standing up, and opens the air supply port 1.
can be closed with the lid 6. At this time, the working lever 4 moves to the lower part of the working hole 3 as shown in FIG. By moving the lever horizontally downward, the lever 4 is attached to the lower edge of the locking convex step 8 as shown in FIG. 3(c).
is locked to prevent rotation of the locking lever 4, as shown in FIG.
)'s air supply port 1 'I! 1.6, it is possible to maintain the rR blocked state. In the embodiment shown in FIGS. 1 to 3, the locking convex step 8 provided in the operation hole 3 allows the rubbing lever 4 to be held in the state in which the lid 6 is rotated so as to close the air supply port 1. By giving the operation lever 4 elastic deformability to curve in the direction of the arrow in FIG. 3(b), the four-operation lever 4 can be formed. By moving horizontally to the lower side of the locking convex step 8, the operating lever 4 can be automatically locked to the lower edge of the locking convex step 8. FIG. 4 shows another embodiment of the present invention, in which the structure for rotating the lid 6 by operating the operating lever 4 is the same as that shown in FIG. The upper surface of the end portion is provided with a protrusion 9 that projects laterally. In this device, from the state shown in FIG. 4(a) in which the lid 6 is opened by operating the operating lever 4 to open the air supply port 1, the operating lever 4 is operated to open the air supply port 1 as shown in FIG. 4(b). Turn the operating lever 4 so that the part protruding from the air plate 2 to the front side faces downward, turn the M6 to stand up, and close the air supply port 1 with the li6, as shown in Fig. 5. As shown, the protrusion 9 engages with the slotted hole 17 of the operating lever 4, and the operating lever 4 and the lid 6 are fixed to each other, and the air supply port 1 is closed with the M6. can be retained. In the embodiment shown in FIGS. 4 and 5, the rotational position of the operating lever 4 is adjusted by the protrusion 9 provided on the lid 6 so that the cover 6 is rotated so as to close the air supply port 1. Holding means 7 for holding
By elastically deforming the operating lever 4, the protrusion 9 can be easily engaged with and disengaged from the long hole 17. Further, in each of the above embodiments, the holding means 7 can be formed without using an independent member, and the M6
There is no need to increase the number of parts in order to maintain the rotational position of the operating lever 4 in the rotated state. [Effects of the Invention] As described above, the present invention includes a holding means for holding the rotational position of the operating lever in a state in which the lid is rotated so as to close the air supply port. It is possible to maintain the air inlet in a closed state and prevent the air inlet from being opened inadvertently.
