Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a dish dryer for drying tableware, and particularly relates to the structure of its lid.

(b) Conventional technology The lid structure of the conventional dish dryer was developed in 1983.
As shown in Japanese Patent No. 6760, it is composed of two lid pieces. In such a conventional structure, the tableware itself or the tableware basket is taken in and out by opening and closing one side of the two-piece lid, but the opening area is small;
Especially for the type that allows you to put in and take out the tableware storage basket,
The work in and out was slow.

Therefore, in order to solve the above-mentioned drawbacks, the applicant of the present invention constructed the lid body with three lid pieces that can be rotated with respect to the main body, and when the drying chamber is closed, the first and second lid pieces are The claw pieces provided at the edges of the overlapping part of the first lid piece and the overlapping parts of the second and third lid pieces engage with each other to hold the second lid piece together. When the center of gravity of the second lid piece is positioned to one side of the third lid body from the center of rotation, when the first lid piece is opened, the second lid piece will open due to its own weight. We have proposed a structure in which the body piece is configured to rotate and the opening area of the lid body is widened.

However, if the center of gravity of the second lid piece is located almost directly above the center of rotation due to a manufacturing error, even if the first lid piece is opened, the second lid There is a problem that the body pieces do not rotate, and when opening the lid, if you let go of the lid before it is completely opened, the first lid piece will fall and collide with the main body. There was a risk that the impact would damage the tableware in the drying room.

(c) Problems that the invention aims to solve This invention was created in view of the above-mentioned problems, and in a case where the lid is made up of three lid pieces, the second lid piece is replaced by the first one. To provide a dish dryer which can be reliably opened in conjunction with the opening of the first lid piece and can prevent the first lid piece from colliding with the main body.

(d) Means for solving the problem The present invention involves engaging the first and second lid pieces at both ends and moving the first and second lid pieces away from each other. A biasing elastic member is provided.

(E) Operation Since the structure is configured as described above, when the first lid piece is opened, the elastic member presses the second lid piece and the first lid piece rotates. and rotate the second lid piece. Therefore, even if the frictional resistance to rotation of the second lid piece is large, the second lid piece can be reliably rotated. When the first lid piece is further rotated with the second lid piece fully open, the repulsive force of the elastic member increases, and the repulsive force causes the first lid piece to open. It opens slowly without colliding with the main body.

(F) Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 8. Reference numeral 1 denotes a dish-shaped main body made of synthetic resin, which is equipped with a heater unit 2 serving as a heat source.
A top plate 4, which also serves as a water receptacle, is provided at its opening, with a water receptacle 3 surrounding the heater unit 2 formed by integral molding. Further, the main body 1 is provided with an enclosing wall 1' extending upward from the front part from the rear part to both sides. A cut surface 5 is formed at the lower rear end of the main body 1, and stoppers 6 are provided at the upper and lower portions of the cut surface 5 to serve as stopping means when opening the first and second lid pieces 9a and 9b, which will be described later. , 6. Reference numeral 7 denotes a metal heat radiation plate which also serves as a water receptacle and is placed above the heater unit 2 so that the water received here falls onto the water receptacle 3.

Reference numeral 8 denotes a synthetic resin tableware storage basket that is housed in and out of a drying chamber 10 formed between the main body 1 and a lid 9 (to be described later). (not shown) are also formed. Reference numeral 9 denotes a transparent synthetic resin lid that covers the upper part of the main body 1 and forms a drying chamber 10 between it and the main body, and includes three lids each having a generally fan-shaped side surface and a U-shaped cross section. It is composed of pieces 9a, 9b, and 9c. The third lid piece 9c has its pivot portion 9
A pivot hole 14 provided at c' is supported through a cylindrical pivot shaft 13 integrally formed on both sides of the enclosure wall 1' of the main body 1, so that the main body 1 is rotatably supported. . In addition, the first and second lid pieces 9a, 9
b is the pivot tube 11 provided on the pivot portions 9a' and 9b'.
The first and second lid pieces 9a, 9 are assembled by inserting and engaging the synthetic resin engaging tubes 12 into a, 11b in a loosely fitted state.
b are preassembled so that they can be handled as one unit. The engagement cylinder 12 is supported through the pivot shaft 13, and the first and second lid pieces 9a, 9b are connected to each other.
is rotatably supported on the main body 1 with the engagement tube 12 as the center of rotation. In the pivoted state, the second lid piece 9b can slide inside the first lid piece 9a, and the third lid piece 9c can slide inside the second lid piece 9b. In addition, there is one drying room.
When 0 is closed, the first sheet 9a and the second sheet 9
Claw pieces 15a, 15 provided on the respective edges of the overlapping portion of b and the overlapping portion of the second sheet 9b and third sheet 9c
b...They engage with each other to hold the second lid piece 9b in this state.

Reference numeral 16 denotes a coil-shaped elastic member inserted into the pivot tubes 11b on both sides of the second lid piece 9b;
6a is abuttingly engaged with a rib 17 provided on the pivot portion 9b' of the second lid piece 9b, and the other end 16b is a through hole 18 provided on the pivot portion 9a' of the first lid piece 9a. Claw part 1
9, and the first and second lid pieces 9a, 9
Both cover pieces 9 are rotated so that b rotates in opposite directions.
Elastic force is applied to a and 9b.

Reference numeral 20 denotes a stop plate made of synthetic resin that prevents the lid pieces 9a, 9b, and 9c from coming off the pivot shaft 13, and the integrally formed legs 21 are inserted into and engaged with the pivot shaft 13 to be fixed to the main body 1. has been done.

When the first lid piece 9a is rotated in the direction of the arrow in FIG. 1 by pinching its knob 9', one end 16a of the elastic member 16 presses the rib 17 of the second lid piece 9b. Then, as the first lid piece 9a rotates, the second lid piece 9b is rotated. Therefore,
When the second lid piece 9b does not rotate and open due to its own weight, that is, when the center of gravity of the second lid piece 9b is closer to the first lid piece 9a than the center of rotation, or when the second lid piece 9b Even when the inner diameter of the pivot tube 11b of the first cover piece 9b and the outer diameter of the engagement tube 12 are close to each other and the frictional resistance increases, the second cover piece 9a rotates. The second lid piece 9b is reliably rotated.
When the second lid piece 9b is completely opened, that is, when the second lid piece 9b is in contact with the stopper 6, when the first lid piece 9a is further rotated, The elastic member 16 increases its repulsive force, and when the first lid piece 9a is completely opened, that is, the first lid piece 9a is in contact with the stopper 6, the elastic member 16 Repulsion force is maximum.

An elastic member is provided to the extent that the first lid piece 9a does not rotate in the closing direction due to the repulsive force of the elastic member 16 when opening, so even if you take your hand off during the opening operation, it will not close. It can be opened slowly without being pushed back in the direction and without colliding with the main body 1.

When closing, by performing the reverse operation of opening, the first lid piece 9a can be rotated with a small force due to the repulsive force of the elastic member 16. Also, the claw piece 15a of the first lid piece 9a is the claw piece 1 of the second lid piece 9b.
5b, the second lid piece 9b rotates in conjunction with the rotation of the first lid piece 9a, thereby closing the drying chamber 10. In this closed position, the repulsive force of the elastic member 16 is minimized, so the first lid piece 9a does not collide with the main body 1 due to the repulsive force, and is handled in the same way as a conventional structure without the elastic member 16. be able to.

In addition, since the first and second lid pieces 9a and 9b are assembled in advance by the engagement tube 12, when the stop plate 20 is removed and the base body 9 is separated from the main body 1,
The first and second lid pieces 9a, 9b will not separate, and therefore the elastic member 16 will not come off.

In this embodiment, a repulsive force is applied in advance to the elastic member 16 so that the first and second lid pieces 9a and 9b rotate in opposite directions even in the closed state. In this state, the repulsive force of the elastic member 16 may be eliminated.

Further, as shown in FIG. 8, the main body 1 is composed of a heating section 22 having a heater unit and a tableware basket 23 placed on the heating section 22, and the upper surface of this main body 1 is covered with the above-mentioned lid 9. Close the lid and remove the dish basket 2 from the main body 1.
Of course, the present invention may also be applied to a dish dryer in which a drying chamber 10 is formed between the lid 9 and the lid 9.

(g) Effects of the invention Since the present invention is configured as described above, the opening area of the drying chamber can be increased, and tableware can be easily taken in and out. In addition, the second lid piece can be reliably opened in conjunction with the rotating operation of the first lid piece, and the first lid piece can be prevented from colliding with the main body. This has effects such as being able to prevent damage to the tableware due to the impact.
