Description

[Detailed Description of the Invention] The present invention relates to a timer fixing part for home appliances such as clothes dryers.

Such timers are used to control the operation of home appliances, and the conventional method of mounting them is either directly on the timer body, or by attaching screws or the like to a protrusion formed integrally on the panel on which the mounting piece protrudes from the timer body. It was to be tightened and fixed using.

In such conventional methods, a mounting piece or the like must be provided on the timer side in some cases, and mounting screws, screwdrivers, etc. must be prepared, and the work becomes detailed and troublesome.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
No installation configuration is required on the timer side, and no installation screws are required, reducing the number of parts.
Another object of the present invention is to provide a timer fixing part for home appliances that can be attached by hand with a single touch without using tools such as a screwdriver.

However, according to the present invention, the purpose of the lever is to fix the timer of home appliances by inserting a timer mounting board on the back side of which the timer is attached into an opening provided in the outer box of the home appliance and fixing it with screws or nail fixing means. At the bottom, four vertical flat elastic protrusions with the tips bent at right angles to form locking claws and having the same height as the width of the box timer to be fixed are attached to each corner of the timer with the locking claws facing inward. They are protruded from the back surface of the board so as to be in contact with each side surface of the nearby quadrilateral, and are protruded from the back surface of the board, and are further provided with a notch in the board so as to protrude and retract from this board surface, and the tip is in a state where the timer is attached. Now, when the timer is placed obliquely in a substantially diagonal direction in a quadrilateral timer mounting part which is located on the side line of the timer and is formed on the inside by four vertical flat elastic protrusions when the timer is installed, A locking claw piece is provided at one of the locations where the front surface of the timer corner projecting outward of the mounting portion is located,
Hook the locking claw piece to the back of the timer and attach it to the timer.
This is achieved by holding the outer surface between the vertical portions of four vertical flat elastic projecting pieces and abutting a locking claw piece on any one side surface.

Hereinafter, the case where the present invention is applied to a clothes dryer will be described in detail with reference to the drawings.

FIG. 1 is a front view of a clothes dryer. In the figure, 1 is an outer box, which has a door 2 in the center for putting in and taking out dry clothes, and a dust filter insertion opening 3 is provided at the bottom of the door 2.

A punching opening 4 for mounting is formed in the outer box 1, into which a panel board 6 with a timer 5 attached to the back side is removably inserted from the outside, and the board 6 is inserted into the outer box 1.
The board 6 is fixed to the outer box 1 by fixing it with screws or by providing claws on the board 6 and fitting it into the outer box 1, and the timer 5 is installed on the surface of the outer box 1.

FIG. 2 is a perspective view showing an embodiment of the timer fixing part of the present invention. In the figure, 5 is a box-shaped timer, and 6 is the above-mentioned panel substrate. The panel substrate 6 is manufactured from synthetic resin.

Four elastic protrusions 7 made of vertical flat plates are provided projecting from the back surface of the panel substrate 6 at the same height as the width a of the timer 5 and having locking claws 7a bent at right angles to the inside of the tips.

The protrusions 7 are protruded from the substrate 6 at positions substantially diagonal to each other in the quadrilateral, that is, at positions where each protrusion 7 abuts the side surface near the corner 5a of the timer 5.

8 in the figure is an opening through which the rotation shaft of the timer 5 passes.

Next, two parallel notches 9 are provided in the substrate 6, and a locking claw piece 10 having a protrusion 10a at the tip protrudes and retracts on the surface of the substrate 6 is formed.

Note that the end of the protrusion 10a connects the timer 5 to the substrate 6.
When the timer 5 is installed on the side of the timer 5, it is on the line of the side surface of the timer 5, and when the timer 5 is placed diagonally on the quadrilateral timer mounting part formed inside by the protruding piece 7 when the timer 5 is installed, it is on the line of the side surface of the timer 5. It shall be located at one of the locations where the front surface of the corner portion of the timer 5 protruding outward from the mounting portion of the timer 5 is located.

Next, the usage and effect will be explained.

FIG. 3 is a front view showing the usage state of the present invention. In order to attach the timer 5 to the board 6, the timer 5 should be oriented diagonally diagonally to the quadrilateral timer mounting part as shown by the two-dot chain line. , the corner 5a
is inserted into the locking claw 7a of the protruding piece 7 so that it is positioned between each protruding piece 7. In this state, the corner of the timer 5 protrudes outward from the quadrilateral timer mounting part, and the protrusion 10a of the locking claw piece 10 is pushed into the surface of the board 6 by the front surface of this protruding corner. There is.

Next, when timer 5 is rotated by hand in the direction of the arrow, protrusion 7 is pushed by the side of timer 5 and tilts slightly outward, and when timer 5 reaches the installation position, protrusion 7 returns to vertical due to its elastic force, locking claw 7a catches on back surface 5b of timer 5, and the vertical portion of protrusion 7 abuts against the outer surface of timer 5.

At the same time, the pressing force of the timer 5 is released, and the protrusion 10a of the locking claw piece 10 comes off the timer 5 and protrudes onto the surface of the board 6, and this protrusion 10a is also released from the timer 5.
As a result, the timer 5 no longer rotates and is firmly fixed to the base plate 6.

In this way, the timer 5 is held between the outer surface 4 and the width direction by the protrusion 7, but when the timer is used to set the time, the knob provided on the surface of the timer 5 is not turned or pushed. As a result, even if a considerable force is applied to the timer 5, the protruding piece 7, unlike the locking claw piece 10, is strong enough to prevent the surface of the board 6 from protruding or bending, so that the force applied to the timer 5 can be reduced. can withstand sufficiently. Note that when the timer 5 is installed, the protruding piece 7 will fall slightly outward when the timer 5 is rotated, but this deformation is very slight, so even if the protruding piece 7 is given this degree of elasticity, the timer 5 There is no possibility that the holding force will be affected.

Therefore, during installation of the timer 5, in order to prevent the protruding pieces 7 from being bent significantly, the timer 5 should be placed in a position where the position of the timer 5 in the board plane direction cannot be controlled in the space between the four protruding pieces 7. I decided to put it first.

When the timer 5 is installed in the correct position, the locking claw piece 10 prevents the timer 5 from rotating. At this time, the locking claw piece 10 itself is structured to protrude and retract from the surface of the board 6 and bend, but since the timer 5 is held by the protruding piece 7, the locking claw piece 10
There is no problem even if 0 itself is not large in intensity.

As described above, the timer fixing part of the home appliance of the present invention has four vertical flat elastic protrusions each having a locking claw bent at right angles to the inside of the tip at the same height as the width of the box timer to be fixed. Each of the hooks protrudes from the board so as to come into contact with the side surface near the corner of the timer, and a notch is provided in the board to form a locking claw piece that extends in and out of the board surface and whose tip is located on the side line of the timer. There is no need to provide any installation structure on the timer body side, and there is no need to use screws or the like as in the conventional case.Furthermore, it can be installed by hand without any tools, making it easy and quick to install. It is possible to perform installation work.

Furthermore, the overall structure is simple, requiring only a protrusion for locking, and can be manufactured at low cost.
