and a bottom portion 14c that is integrally connected to b and forms the bottom of the lower annular portion 14b. The bottom portion 14c is formed with intake holes 19 ...
Legs 18 are provided on the lower surface of c.

The gutter groove portion 15 includes an upper annular portion 14a of the annular partition wall 14, a wall portion facing the portion 14a, that is, a lower portion of the peripheral wall 11a of the dryer body 11 in this embodiment, and the upper annular portion 14a and the peripheral wall 11a. And the bottom wall 11b, which are integrally connected to each other. Therefore, the gutter part 1
5 is arranged so as to surround the upper part of the central storage chamber 16. The bottom wall 11b of the gutter groove 15 has a step or an inclination, and a drainage hole 17 is formed at the lowermost portion thereof.

A metal heater box 20 is housed and fixed in the central storage chamber 16 with a ventilation gap g provided between the bottom portion 14c of the annular partition wall 14 and the upper and lower annular portions 14a and 14b. The upper end of the box 20 is opened, and an electric heater 21 is attached inside.

A water receiving plate 22, which also functions as a heat radiating plate, is arranged above the central storage chamber 16 and is attached to the upper end of the heater box 20. This water receiving plate 22 is an electric heater 21.
And the upper part of the central storage chamber 16 is covered. Further, the peripheral portion of the water receiving plate 22 is located above and apart from the upper annular portion of the annular partition 14 and slightly overlies the inner side of the gutter groove portion 15. Therefore, a hot air outlet d is provided between the peripheral portion of the water receiving plate 22 and the upper annular portion, and the outlet d is connected to the upper end of the ventilation gap g . Moreover, the peripheral portion of the water receiving plate 22 is considerably separated from the peripheral wall 11a of the dryer main body 11. That is, in this way, the water receiving plate 22 is disposed in the lower central portion of the dryer main body 11.

In this embodiment, in order to make the rise of warm air more uniform, the water receiving plate 22 is formed in the shape of a pyramid so that the water receiving plate 22 gradually decreases from the center toward the peripheral edge, but the present invention is not limited to this.

In the dryer main body 11, a draining member 23 made of metal or synthetic resin is detachably accommodated by covering the water receiving plate 22. 24 is a water receiving plate 2
2 is a leg member to be placed above 2, and is attached to the draining member 23, for example. A plurality of leg members 24 are provided at intervals, or have an annular shape as shown in this embodiment, and in the case of an annular shape, a water passage groove 24a is provided in a portion in contact with the bottom wall 11b.

In the case of this embodiment, the draining member 23 facilitates cleaning, and the peripheral wall 11a of the dryer main body 11 is used.
In order to further improve the storage capacity of the tableware by forming a tableware storage space between them and the tableware storage structure, in order to reduce the cost of the tableware storage structure, a substantially flat plate-shaped one having a plurality of through holes 23a is used Is shaped to be as close as possible to the dryer main body peripheral wall 11a. However, the draining member 23 may have a cage shape.

A water receiver, for example, a cup 27, for receiving water passing through the drain hole 17 is provided outside the dryer main body 11. That is, a decorative frame 25 made of synthetic resin is attached to a part of the space A below the trough portion 15 that surrounds the central storage chamber 16.
The cup 27 is detachably attached in a side-by-side arrangement with respect to FIG. A time switch 26 is also attached to the decorative frame 25.

In the tableware dryer having the above construction, the annular partition wall 14 forming the central storage chamber 16 containing the heater box 20 and the gutter groove portion 15 for receiving water drops guided by the water receiving plate 22 are made of synthetic resin. With the structure in which it is integrally provided with the dryer main body 11 and the outer surfaces thereof are exposed to the outside of the dryer main body 11, the bottom of the tableware dryer does not have a double wall structure. Therefore, the number of parts and the number of assembling steps can be reduced.

Next, the operation of the tableware dryer having the above construction will be described. First, the washed dishes are arranged on the draining member 23 and stored in the dryer main body 11, the lid 12 is covered, and the time switch 26 is set. Then, the electric heater 21 generates heat to heat the water receiving plate 22 and the like,
By these, the air that has entered the central storage chamber 16 through the intake holes 19 is heated and becomes warm air and rises. Heater box 20 housing electric heater 21 and water receiving plate 22
Is disposed in the center of the lower part of the dryer main body 11, so that warm air rises around these and is used for drying dishes.

That is, the warm air flows between the draining member 23 and the lid body 12 as shown by the arrow in FIG. 1, generating an ascending flow passing through the central portion side and a vortex flow formed outside thereof, The water on the tableware is evaporated and discharged from the exhaust hole 13. In this way, natural convection of warm air is performed almost evenly.

In the above drying, the annular partition wall 1
The outside air flowing from the intake hole 19 of the bottom portion 14c of No. 4 passes through the ventilation gap g between the annular partition 14 and the heater box 20, and then flows through the hot air outlet d connected to the upper end of the gap g. As a result, the air becomes warm and flows out toward the upper part of the dryer main body 11 as described above.

By providing the air circulation passage as described above, the annular partition wall 14 heated by radiant heat from the heater box 20 side can be cooled by the air passing through the circulation passage. In addition, the outer surfaces of the annular partition wall 14 and the gutter groove portion 15 are exposed to the outside air outside the dryer main body 11, so that heat radiation from the outside surface to the outside air is easy.

Therefore, since the temperature rise in the trough portion 15 is reduced, it is possible to prevent the generation of water vapor in the trough portion 15 that keeps the dryer main body 11 and hinders the drying of the dishes. Therefore, the drying efficiency can be improved.

At the same time, as mentioned above, the annular partition 14
Also, since the temperature of the gutter groove 15 does not rise so much, the dryer main body 11 integrally including these can be made of an inexpensive synthetic resin material having low heat resistance. Therefore, as described above, in combination with the small number of parts and the small number of assembling steps, the tableware dryer can be obtained at low cost.

In the case of this embodiment, since the gutter groove portion 15 is not in contact with the water receiving plate 22 to be heated,
Heat conduction from the water receiving plate 22 or the like to the trough portion 15 is also prevented.
As a result, the heat itself is not wasted in evaporating the water on the trough portion 15, and the drying efficiency is further improved.

Further, when the tableware is placed on the water draining member 23, the water drops dropped from the tableware onto the water draining member 23 pass through the member 23 from the water receiving plate 22 to the periphery below the water receiving plate 22. It is guided to the formed trough portion 15, then introduced from the drain hole 17 into the cup 27 arranged outside the dryer main body 11, and is discarded through the cup 27 at a proper time. Further, the water droplets dropped from between the water draining member 23 and the peripheral wall 11a of the dryer main body 11 are dropped directly into the gutter groove portion 15 and are drained as described above. The gutter groove portion 15 is an upper annular portion 1 which stands upright with respect to a bottom wall 11b thereof.
4a, the bottom wall 11 is formed by this portion 14a.
The water on b can be prevented from entering the central storage chamber 16.

That is, as described above, since water drops from the tableware can be promptly introduced into the cup 27 and water can be prevented from entering the central storage chamber 16, water does not accumulate on the inner bottom of the dryer main body 11. . Moreover, since the gutter part 15 is provided so as to surround the heater box 20 and has a considerably large width, the gutter part 15 can be easily wiped and cleaned using a cloth or the like after removing the draining member 23.

In the case of the tableware dryer shown in the above-mentioned embodiment, since the annular partition wall 14 is provided in the lower portion of the dryer body 11, the annular wall portion 14 is provided outside the lower portion of the dryer body 11. A lower space A of the trough part 15 is formed which faces the outer surface of the lower annular portion 14b and the lower surface of the bottom wall 11b. Since the cup 27 for receiving water is arranged in the lower space A by using the lower space A, the cup 27 is not arranged below the heater box 20 and the central storage chamber 16 but in the lateral direction. Can be placed side by side. Therefore, the space can be effectively used, and the cup 27 does not cause the height of the entire dryer to be large. Therefore, it is possible to reduce the height h of the dryer main body 11 and thus the height of the entire dryer to realize a compact size.

Moreover, in the case of this embodiment, since the cup 27 is arranged outside the dryer main body 11 as described above, it is not exposed to the temperature atmosphere in the dryer main body 1, and Radiant heat from the heater box 20 can be blocked by the annular partition wall 14. Therefore, the electric heater 2
It is possible to prevent the water contained in the cup 27 from being evaporated due to the energization of 1 for a long time. For this reason, it is possible to reduce the amount of water vapor that remains inside the dryer main body 11 and reduces the drying efficiency and adversely affects the electrical components from being supplied from the cup 27 into the dryer main body 11. Similarly, since the timer 26 is also disposed outside the dryer main body 11 by utilizing the lower space A, this is the dryer main body 1 at the initial stage of starting the drying of dishes.
It is not exposed to the damp atmosphere in 1 and has high electrical safety even in long-term use.

Further, in the case of this embodiment, since the central storage chamber 16 protruding downward is formed in the central portion of the bottom wall 11b of the dryer main body 11, the lower space A is provided around it. The whole dryer can be carried by turning fingers into this space A, which is convenient in handling. That is, the lower part of the dryer main body 11 (the lower surface of the bottom wall 11b in the case of the present embodiment) can be held by holding a finger, so that the whole dryer can be hung. Instead, it can be held stably to support from below.

It is needless to say that the tableware dryer having the above structure can improve the strength of the lower portion of the dryer main body 11 by including the annular partition wall 14 defining the central storage chamber 16.

Although the above-mentioned embodiment is constructed as described above, in the practice of the present invention, the dryer main body, the bottom wall, the peripheral wall, the annular partition walls and their respective annular portions, the central storage chamber, The specific structure, shape, position, material and the like of the heater box, the electric heater, the water receiving plate, the gutter groove portion, the gap, and the hot air outlet are not limited to the one embodiment and can be implemented in various configurations. Of course.

[0031]

In the tableware dryer of the present invention described above, since the bottom of the tableware dryer does not have a double wall structure, the number of parts can be reduced and therefore the structure is simple. Then, it flows in from the bottom portion of the annular partition wall, passes through the ventilation gap between the inner surface of this partition wall and the heater box, and passes through the annular partition wall.
It is formed between the wall and the water receiving plate and communicates with the upper end of the ventilation gap.
The air flow that flows out from the hot air outlet toward the top of the dryer main body can cool the annular partition wall that is heated by the radiant heat from the heater box side, so that the temperature rise of the gutter groove part is suppressed and it remains on the upper surface. The evaporation of water can be reduced, and thus the efficiency of drying dishes can be improved. Further, with the suppression of the temperature rise of the annular wall portion and the gutter groove portion as described above, the dryer main body can be made of an inexpensive synthetic resin material having low heat resistance, and in combination with the reduction of the number of parts. , You can get a tableware dryer cheaply.
