Description

[Detailed explanation of the idea] The present invention relates to a dish dryer.

Conventionally, dish dryers with various specifications have been provided and put into practical use.

However, conventional dish dryers are equipped with a heating element at the bottom of the water catch plate at the inner bottom of the dish dryer, so when water droplets from the dishes fall onto the water catch plate, heat is generated to dry the inside of the dish dryer. Much of the body's heat was used to evaporate the falling water droplets.

Therefore, the dish dryer is always filled with saturated water vapor.
This water vapor comes into contact with cold dishes, turns into water droplets, and falls onto the water receiving plate again, and the current situation is that the dishes are dried by repeating this process repeatedly.

Therefore, most of the heat generated by the heating element is used for evaporating the falling water droplets, resulting in extremely poor thermal efficiency for drying dishes.

Therefore, this invention was devised with the aim of improving thermal efficiency by keeping the inside of the dish dryer constantly dry by allowing water droplets to flow down and minimizing the generation of steam. The gist of this is that the required dish dryer consists of a picture frame body that is capable of accommodating the specified tableware and is equipped with a heat source at the bottom. An inner plate with protruding stripes is disposed above the bottom plate of the picture frame main body, a heating element is housed in the housing groove, and an appropriate number of leg rods are installed on a cover plate having an outer diameter larger than the flat surface of the housing groove. The present invention consists in that the lower part of the leg of the vertically disposed lid body is fixed to the storage groove, and a hot air outflow gap is formed between the storage groove and the cover plate.

An embodiment of the present invention will be described below with reference to the illustrated example.

Reference numeral 1 denotes a picture frame main body with an open front, which is composed of a top plate 2, side plates 3, a bottom plate 4, and a nest plate 5.

Above the bottom plate 4 of the picture frame body 1, there are
An inner plate 6 is provided that slopes downward toward the front left side, and a top plate I is provided below the upper plate 2 in a downward arc shape toward the back.
A front door 8 made of transparent resin is provided at the front so that it can be opened and closed freely.

The inner plate 6 has an appropriate number of chevron-shaped protrusions 9 extending in the front left and right direction, for example, two protrusions extending parallel to each other at appropriate intervals, and exhibiting an inverted V-shape, arc-shape, etc. in cross section. A storage groove 10 is recessed at the top of the protrusion 9.

In addition, a drain hole 11 is bored in the front left side of the inner plate 6, and between the inner plate 6 and the bottom plate 4 below the drain hole 11,
A water reservoir plate 12 that can be freely pulled out from the bottom plate 4 is provided.

Further, a heating element 13 made of a coiled nichrome wire is arranged in the storage groove 10 as a heat source.

The front door 8 is formed to open upwardly around a protruding shaft 14 protruding from the upper front end of the inner surface of the side plate 3 of the picture frame main body 1, and after being in a horizontal state, the front door 8 opens upward from the top of the picture frame main body 1 It can be inserted between the board 2 and the top board 1.

On the other hand, separately from the picture frame body 1, a cover plate 15 having a substantially chevron-shaped cross section and having an outer shape larger than the planar shape of the storage groove 10 is formed, and a total of four leg rods 16 are vertically provided at the front and back of both ends of the cover plate 150. Then, a lid body 1T is formed.

The leg rods 16 are formed so that the space between the pair of mutual gaps at both ends of the cover plate 15 has a front-to-back width that substantially matches the length of the storage groove 100 in the front-back direction.

The lid body 17 is fixed to the lower part of the leg rod 16 so as to cover the storage groove 10 of the protrusion 9 of the inner plate 6.

At this time, only the lower part of the leg rod 16 of the lid body 17 is fixed to the storage groove 10, and a hot air outflow gap 9A is formed between the cover plate 15 of the lid body 11 and the edge of the storage groove 10 side. shall be kept.

To explain this in detail, for example, as shown in FIG. An L-shaped support part that abuts the edge is arranged on the upper part, and the two are integrally formed, and the pressure part is fixed to the storage groove 10, and a predetermined hot air outflow gap 9A is created at the height of the support part. It is designed so that it can be formed.

By doing so, the fixation to the storage groove 10 and the hot air outflow gap 9
It is convenient because A can be easily formed and can be easily attached and detached, and of course, it is not limited to such fixing means and gap forming means.

On the upper left and right sides of the bottom plate 4 inside the picture frame main body 1, fixing parts 20 in the shape of planar grooves are provided with grooves facing each other.

A lower shelf 21 on which predetermined tableware to be dried is placed is formed on the upper part of the fixing part 20 by mutually extending the lower shelf 21 thereon.

In addition, a pair of swinging arms 22 having the same length are pivotably supported near the front and rear ends of one of the fixed parts 200, respectively, and the upper parts of these swinging arms 22 are supported by mutual support. A swinging pull-out mechanism 24 is formed by pivotally supporting the arm 23.

Further, a swinging pull-out mechanism 24 is formed on the other fixed part 20 by similarly supporting a swinging arm 22 and a support arm 23, and a handle 25 is formed on a part of the front end of each support arm 23. They are connected and fixed by a pull-out arm 26, and an upper shelf 27 for placing tableware, etc., between each support arm 230 is formed so that it can be detachably installed in an erected state.

In addition, a swinging arm 22 is installed at an appropriate position on the nest plate 5 of the picture frame body 1.
A stopper 28 is provided with which the rear end of the support arm 23 collides when the oscillating arm 22 is tilted slightly backward, and a stopper 29 with a substantially inverted side surface that collides with the swinging arm 22 when the swing arm 22 is tilted forward is provided.

Furthermore, a return arm 31 is fixed to the side plate 3 side of the picture frame body 1 of the swing arm 22 which is pivotally supported at the rear of the fixed part 20, and the swing shaft 30 which is the pivot point of the fixed part 20. The return arm 31 and the fixed part 20 are respectively provided with impact protrusions 32 and 33 protruding from each other at different angles so as to face each other.
Between the fixing part 20 and the return arm 31 at
33, a torsion coil spring 34 is attached whose protruding ends are narrower than each other.

In FIG. 1, 35 is a time switch for heating the nichrome wire 13, 36 is a pilot lamp that indicates when heating is in progress, and 31 is a drain hole 38 drilled in the upper part of the front door 8. This is a suction hole for intake into the frame body 1.

Further, 39 in FIG. 2 is a plug.

Next, the use of the present invention will be explained.

Without opening the door 8, insert it between the top plate 2 and the top plate I of the picture frame main body 1.

Next, when the handle 25 is pulled and the swinging arm 22 in the swinging pull-out mechanism 24 is pulled forward and downward, the swinging arm 22 becomes vertical at the dust neutral point, and then moves forward while drawing an arcuate trajectory. It will be tilted.

At this time, the swinging pull-out mechanism 24 is controlled by the fixed part 20 and the pair of swinging arms n1 support arms 23 of the same length, so the support arm always moves from the horizontal state to the upper loading shelf. 27 also maintains a horizontal state.

When the oscillating arm 22 is swung downward, the collision protrusion 32 of the return arm 31 fixed to the oscillation arm 22 will eventually collide with the tip of the torsion coil spring 34, and between it and the collision protrusion 33 of the fixed part 20, It pinches the torsion coil spring 34 and collides with the stopper 29 while gradually accumulating torsional energy.

After that, place the tableware on the upper shelf 27, take the handle 25 and push it upwards, and move the swinging arm 22 upward until the rear end of the support arm collides with the stopper 28 of the nest plate 5. Shake it.

When the upper shelf 27 starts swinging upward, the upward swing can be performed with a small force due to the elastic force accompanying the release of torsional energy of the torsion coil spring 34.

On the other hand, after that or before that, tableware is placed on the lower mounting table 21.

Next, the front n8 is closed and the time switch 36 is set to a predetermined time to start drying the dishes.

During the drying of the dishes, water droplets fall from the dishes, and these droplets slide off the protrusions 9 of the inner plate 6, pass through the drain holes 11, and collect in the water collecting tray 12.

When the dishes are being dried, the heating element 13 is stored in the storage groove 10 recessed at the top of the chevron-shaped protrusion 9 protruding from the inner plate 6, and the storage groove 10 is covered by the lid 17. Water droplets from dishes and the like are not accumulated near the heating element 13 but are discharged along the base of the protruding strip 9, so that the amount of heat from the heating element 13 is not used for evaporation of the falling water droplets.

Therefore, the interior of the lid frame main body 1 is not filled with water vapor and is kept in a dry state at all times, so that moisture adhering to the surface of the tableware etc. is easily evaporated, and the tableware can be quickly dried with high thermal efficiency.

In addition, since the lid body 17 covers the storage groove 10 with the cover plate 15 which is larger than the plane of the storage groove 10, water droplets do not adhere to the heating element 13, and even if the storage groove 10 is covered, the lid body 17 Since there is a hot air outflow gap 9A between the cover plate 15 and the storage groove 10, the hot air can easily rise, and drying can be performed quickly, which also helps improve thermal efficiency.

Further, the installation location of the lid frame main body 1 is not particularly limited, but if it is installed at the upper front of the sink where the dishes are washed, it is convenient because the dishes that have been washed can be immediately dried.

In such a case, if the upper mounting table 2T is formed so as to be able to swing downward as in the embodiment, there is an advantage that even a short person can use it easily.

Furthermore, if a torsion coil spring 34 is provided as in the embodiment,
Since the swinging descent speed is reduced, the tableware will not be damaged or thrown out from the upper shelf 21 due to the impact of falling.

In addition, when the upper shelf 27 starts swinging upward, the elastic force of the torsion coil spring 24 allows the upper shelf 27 to swing upward with a small force, making it extremely easy to operate.

The upper loading shelf 27 is attached to the supporting arms 23 that form the swinging pull-out mechanism 24 together with the fixed part 20 and a pair of swinging arms 22 of the same length, so that the upper shelf 27 is always kept horizontally. Since it moves up and down, the dishes will not fall off.

In addition, in either case of upward swinging or downward swinging, after the swinging arm 22 passes the vertical state, which is the neutral point of the swinging pull-out mechanism 24, it will swing in either direction due to its own weight. It shakes and operates as a so-called semi-automatic.

As mentioned above, the present invention does not use the heat of the heating element to evaporate the water droplets falling from the tableware, so the interior of the picture frame body is not filled with water vapor, and the heat of the heating element is used to evaporate the water droplets that fall from the tableware into the hot air for drying the dishes. Since it can be used extremely effectively as a fuel, it has extremely beneficial effects in practice, such as improving thermal efficiency.
