Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a top plate and a lid of a fully automatic washing machine.

[0002]

2. Description of the Related Art For example, when an upper plate is attached to a machine frame as disclosed in Japanese Utility Model Laid-Open No. 4-64380, screws are screwed at a rear position of a washing machine which is invisible from the front because of its design. The electrical equipment control parts are installed on the back surface of the top plate or on the machine frame with the top plate removed.

On the other hand, an upper lid provided on the top plate for opening and closing the laundry inlet is folded in two in the front-rear direction and can be opened and closed by a hinge composed of a bearing and a support shaft.

[0004]

In the above-mentioned conventional structure, the upper plate must be removed from the machine frame in order to expose the electrical component control parts during service work such as maintenance and inspection. However, since it is screwed to a position lower than the top surface of the top plate, the position of the screw cannot be seen from the front and tools cannot be used. Therefore, when removing the screw, the washing machine must be pulled out to the front. In particular, when the clothes dryer is integrated with the washing machine via the support arm, the clothes dryer must be pulled out and the workability is poor.

On the other hand, in order to improve the opening / closing operability of the upper lid, the thickness of the resin-molded upper lid is reduced to reduce the weight. However, since the laundry inlet has a fairly large diameter, the top lid itself is the full width of the washing machine, so the center of the top lid is completely suspended in the air, and the force from the top is great. It is easy to be deformed when applied. Especially in ordinary households, there are many cases in which a basket is placed on the washing machine (upper lid) and dirty clothes are put in it, so the weight of the clothing is added to the upper lid, and the weight is integrally molded with the upper lid. The support shaft of the hinge acts as a stress, and the support shaft is broken and the bearing is cracked.

The present invention solves the above-mentioned conventional problems.

[0007]

According to the present invention, a top cover having an opening for loading laundry is mounted on the upper surface of a machine frame containing an outer tub and a washing / dehydrating tub, and an upper lid for covering the opening. In the one in which the top plate is openably and closably attached,
An upper part of the upper part of the opening behind the opening is formed with a component storage chamber having an upper opening, and a cover for covering the upper opening of the component storage part is fixed to the upper plate with a screw from above, and the clothes are installed above the washing machine. A drain port for guiding the drain water of the dryer to the outer tank is provided in the vicinity of the mounting portion of the cover, and the drain port and the screw are covered by a cap detachably attached to the cover.

A machine frame having an outer tub and a washing / dehydrating tub built therein, a top plate having a laundry loading opening mounted on the top surface of the machine frame, and a resin for opening and closing the opening are formed. A top lid, the top lid comprising first and second lid pieces,
While pivotally supporting the first lid piece on the upper plate so as to be openable and closable,
In a structure in which a hinge composed of a bearing and a support shaft integrally provided on the adjacent side portions of the both lid pieces is openably connected, the hinges are formed at both ends, and the support shaft is inserted into the bearing up to its root. It is composed of a hinge A and a hinge B formed in a central portion other than the both ends and having a support shaft inserted into the central portion.

[0009]

The electrical control parts of the washing machine installed in the parts storage room can be seen from the front because the screws fixing the cover to the top plate can be seen when the cap attached to the cover is removed without moving the washing machine. By simply removing this screw, the cover that covers the opening of the parts storage chamber can be removed for maintenance and inspection work.

Further, the load applied to the central portion of the upper lid is not always applied equally to the two lid pieces. For example, when a load is applied to the first lid piece, this load is applied to the hinge B. The force applied to the hinge B acts in the direction of bending the support shaft via the bearing. However, since the support shaft of the hinge B is inserted into the bearing only up to the central portion, the force applied to the support shaft is dispersed over the support shaft and the support shaft is bent (elastically deformed).
To prevent the spindle from breaking.

In this manner, the boss portion 11 formed in the component storage chamber 9 is fixed to the mounting portion 13 formed on the cover 10 with the screw 14, and the drain port 17 provided in the vicinity of the portion is collectively capped. Since it is covered with 18, the appearance of the washing machine 1 is not impaired.

Next, an embodiment of the upper lid 6 of the present invention will be described with reference to FIGS. 2, 6 and 7. Reference numeral 23 denotes a lid support shaft that pivotally supports a first lid piece 6a obtained by dividing the upper lid 6 on the upper surface plate 4 so as to be vertically openable and closable. 24 is a bearing integrally formed on the upper lid 6 which is resin-molded on the first lid piece 6a adjacent to the second lid piece 6b, and 25 is the same resin on the second lid piece 6b on the side facing the bearing 24. The support shaft is integrally formed with the formed upper lid 6. The hinge 7 is constructed by combining the bearing 24 and the support shaft 25. The hinges 7 provided at both ends of the upper lid 6 are referred to as hinges A, and the hinges 7 provided at the central portions other than both ends are referred to as hinges B. Thus, the hinge A inserts the support shaft 25 into the bearing 24 up to its root, and the hinge B inserts the bearing 24.
The support shaft 25 is inserted to the center of the shaft. Reference numeral 26 is a handle for opening and closing the upper lid 6 provided on the second lid piece 6b.

When the laundry is vigorously placed on the upper lid 6 of this structure, or when the weight is supported by placing a hand on the central portion of the upper lid 6 by the operation of drying, this load is evenly distributed between the two lid pieces. It does not always join. For example, when the load P is applied to the side of the first lid piece 6a as shown in FIG. 7, the first lid piece 6a descends by Δt as shown by the alternate long and short dash line, and the load is applied to the hinge B. The force applied to the hinge B is applied in such a manner that the bearing 24 descends corresponding to the descending size and pushes down the central portion of the support shaft 25 protruding in the horizontal direction, and the base of the support shaft 25 is bent. .

However, since the support shaft 25 of the hinge B has the bearing 24 inserted only up to its central portion, the stress applied in the direction in which the support shaft 25 is broken is dispersed over the support shaft 25 and curved (made of resin). It is deformed by elastic force). Even if a load is applied to one of the lid pieces in this way, the stress is dispersed throughout the support shaft 25 and the support shaft 25 is curved by utilizing the elastic force of the resin. Since the weight is reduced by and only the stress after dispersion is received, the hinge B itself is prevented from being damaged, and the upper lid 6 is not damaged.

At the position of the hinge B, the support shaft 25 is attached to the bearing 24.
If the hinge A having the configuration inserted up to the root is brought, the bearing 24 and the support shaft 25 will be damaged because the concentrated stress when the support shaft 25 descends by Δt is received.

It should be noted that both ends of the upper lid 6 have a small amount of downward movement Δt even when a load is applied, and do not apply a large stress that breaks the roots of the bearing 24 and the support shaft 25. Therefore,
In order to prevent rattling of the first lid piece 6a and the second lid piece 6b, the bearing 24 has hinges A inserted up to the root of the support shaft 25 at both ends of the upper lid 6.

[0023]

According to the first aspect of the present invention, the maintenance / inspection work of the electrical equipment control parts mounted in the parts storage chamber can be performed only by removing the cover upward without moving the washing machine. Even if the upper side plate is provided with an upper opening component storage chamber, the cover for covering the component storage chamber is fixed to the upper face plate from above with a screw, and the drain port formed in the vicinity thereof can be collectively covered with the cap. It does not spoil the appearance.

According to the second aspect of the present invention, the hinge A is integrally formed on both ends of the first and second lid pieces of the resin-molded upper lid, which are adjacent to each other. The rattling at the time of assembling one piece is prevented, and in the hinge B at the central portion other than both ends, the stress is dispersed over the entire supporting shaft so that the supporting shaft can be bent freely by the resin elastic force. Even if the upper lid is elastically deformed downward due to a load, the hinge B can also be elastically deformed to prevent the upper lid from being damaged.
