Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application)
The present invention relates to a door opening/closing device for a dryer or the like that is stored in a recess formed in a front plate in a closed state.

(Prior Art) In recent years, for example, in a drum dryer, the following configuration has been considered in order to open the door for opening and closing the clothes entrance by pressing a push button. That is, the side edge of the door is rotatably supported on a front plate on the front side of the dryer main body so as to open and close the clothes entrance, and a lock member is rotatably provided on the back side of the front plate. This locking member includes a claw part that engages with an engagement hole formed on the side edge of the door opposite to the pivot to lock the door in the closed state, and a lever part located on the opposite side of the claw part. By pressing a push button provided on the front plate, the lever portion is pressed, and the lock member is thereby rotated so that the claw portion is displaced in the disengagement direction. In this case, in the closed state, the door is housed in a recess provided in the front plate, and is in the closed state substantially flush with the front plate to enhance the design effect. In addition, when the door is in the closed state, the door is biased in the opening direction by elastically compressing the gasket provided between the door and the front plate, or by a special spring, and the push button is pressed. When the engagement by the locking member is released, the door is rotated open so that it comes out of the recess in the front plate due to the elastic force of the locking member. After this, if necessary, the user can place his/her hand on the periphery of the door. The structure is such that the door can be completely opened by hanging it.

However, with the above configuration, if the dryer is installed with an upward tilt, even if the push button is pressed to open the door once, the door will open due to the return rotation caused by the tilt of the dryer. It immediately returns to the recess in the front plate, and is almost completely stored in the recess again. For this reason, it is not possible to securely place a hand on the door, making it difficult to open the door.

(Problem to be solved by the invention) In this way, with conventional door opening/closing devices for dryers, etc., when the main body of the device is installed in an upwardly tilted state, even if the door is opened, it immediately opens and closes. Since the door returns to the recess in the front panel, there is a problem in that it becomes difficult to open the door because the door cannot be reached with the hand.

The present invention was devised to eliminate the above-mentioned problems, and its purpose is to create a dryer that can reliably open the door even if the main body of the device is installed with an upward slope. We provide door opening/closing devices such as:

[Structure of the invention] (Means for solving the problem) The door opening/closing device for a dryer, etc. according to the invention includes a recess formed in the front plate of the main body of the device, and a clothes entrance and exit formed in this recess. , a door rotatably provided on the front plate to open and close the clothing entrance and stored in the recess substantially flush with the front plate when closed; an elastic body that resiliently biases the door in the opening direction; an engaging portion and a handle provided on the side wall of the door; and an opening formed on the side wall of the recess and facing the engaging portion. and a claw portion which is constantly urged by a biasing means to protrude from the opening into the recess, and resists the biasing force of the biasing means and the elastic force of the elastic body. A locking member whose claw engages with the engaging portion to lock the door in a closed state when the door is housed in the recess, and a locking member that locks the door in the closed state when the door is closed; It is configured to include an operating member that is released against the urging force of the urging means.

(Function) With the door closed, when the operating member is operated against the biasing force of the biasing means to disengage the claw part and the engaging part, the door is opened by the elastic force of the elastic body. Rotate in the opening direction. When the operation of the operating member is released, the claw portion advances again into the recessed position by the urging force of the urging means. In this case, if the main body of the device is installed with the front tilted upward,
Once the door has been rotated in the opening direction, it may be rotated closed so as to return to the recess in the front plate, but in this case, the claw part that is already in the protruding position within the recess will cause the door to close.
The door is blocked in a state in which it protrudes forward by a predetermined distance from the front plate. Therefore, the handle portion is exposed from the recess and can be hung on the handle portion, allowing the door to be opened reliably.

(Example) An example in which the present invention is applied to a dryer will be described below with reference to the drawings.

First, in FIG. 5 showing the overall configuration, 1 is a rectangular cylindrical outer box, 2 is a front plate attached to the front of this outer box 1, and this front plate 2 has a rectangular recess that recesses backward. 3 is formed. A circular clothing entrance 4 is formed in the center of the recess 3, and a rectangular opening 5 is formed on the right side of the recess 3, and an operating panel 6 is flush with the front plate 2 in correspondence with the rectangular opening 5. It is installed so that The left side wall of this operation panel 6 constitutes the right side wall of the recess 3,
The left side wall of the operation panel 6 has an opening 6a.
(See FIG. 1) is formed. Although not shown, the well-known drum, drum drive device, fan device, heater, etc. that constitute the drying chamber are provided inside the outer box 1, and these constitute the dryer body corresponding to the main body of the device. Ru. 7 is a rectangular door, with pivots 7a, 7a protruding from the top and bottom of the left edge of this door;
An engagement hole 8 (engagement part) and a handhold part 9 are provided on the right side wall.
(See FIG. 3) is formed. This door 7 is rotatably attached to the front plate 2 by fitting a pivot 7a into a bearing hole 2a formed in the front plate 2, and is configured to open and close the clothing entrance/exit 4. It is housed in the recess 3 of the front plate 2 and becomes substantially flush with the front plate 2 and the operation panel 6. Reference numeral 10 denotes a gasket provided at the periphery of the clothing opening 4, which has an annular hollow portion 10a.
When the door 7 is closed, as shown in FIG. 1, the annular protrusion 7b provided on the back side of the door 7 compresses and seals the door 7, and thus acts as an elastic body that provides an elastic force in the opening direction to the door 7 in the closed state. act. Reference numeral 11 denotes a locking member, which is attached to the main shaft portion 12 as shown in FIG.
The claw portion 13 is attached to the holder. Main shaft part 1
A pivot shaft 12a is provided protruding from both ends of the operating panel 6, and is rotatably supported by a pair of support pieces 6b integrally provided on the back surface of the operating panel 6. The claw portion 13 is provided so as to rotate integrally with the main shaft portion 12 by engagement with a rotation stop pin 12b protruding from the main shaft portion 12. This claw portion 13 is integrally formed with an elastic piece 14 as a biasing means, which is attached to a receiving piece 15 protruding from the back surface of the operation panel 6.
The claw portion 13 is constantly biased in the direction of arrow A in FIG. As a result, the claw portion 13
is always biased to a protruding position from the opening 6a into the recess 3, and when the door 7 is housed in the recess 3, it engages with its engagement hole 8 to close the door 7. to lock. On the other hand, the main shaft portion 1 of the lock member 11
2 is provided with a protruding piece 16 extending on the opposite side of the door 7, and the tip of a push button 17 as an operating member provided on the operating panel 6 comes into contact with this protruding piece 16. The push button 17 is provided at the lower part of the operation panel 6, and as shown in FIG. is energized by In addition, in Figure 6, 20
is a door switch, its actuator 20
A is pressed by a pressing protrusion (not shown) of the door 7 when the door 7 is in the closed state.

In the above configuration, when the push button 17 is pressed when the door 7 is locked in the closed state, the tip of the push button 17 locks the lock member 11.
The protrusion 16 of the lock member 11 is pressed, and the lock member 11

is rotated in the direction of arrow A by the elastic force of the elastic piece 14, and the tip of the claw portion 13 returns to the protruding position from the opening 6a into the recess 3. At this time, if the dryer is installed on a shelf or the like in a substantially horizontal state, the door 7 will not rotate open due to the force of the disengagement and return naturally into the recess 3. Therefore, if necessary, the user can place his/her hand on the handle portion 9 of the door 7 to completely open the door 7, and then take in and take out clothes from the clothes entrance 4.

However, if the dryer is installed with the front tilted upward, for example, even if the push button 17 is pressed to open and rotate the door 7, a force is applied to the door 7 to return and rotate it. , the door 7 immediately tries to return into the recess 3 of the front plate 2.

However, since the claw 13 is already in the recess 3 in a protruding state under the urging force of the elastic piece 14 (see FIG. The door 7 is abutted and is blocked in a state where it protrudes forward from the front plate 2 by a distance L (see Fig. 3).
The handhold portion 9 is now exposed. Therefore, in this embodiment, even if the dryer is installed in an inclined state and the door 7 returns to the recess 3 immediately after opening, it is impossible to insert a finger into the hand grip 9. It is possible to put a hand on the door 7 and open the door 7 reliably.

In the above embodiment, the gasket 10 is attached to the front plate 2.
Although the gasket 10 is provided on the door 7 side, the gasket 10 may be provided on the door 7 side. In addition, the present invention is not limited to the above-mentioned embodiment, and for example, the claw portion 13 of the locking member 11 can be
