【Example】

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

FIG. 1 is a sectional view of a tableware dryer showing an embodiment of the present invention, and FIG. 2 is a sectional view of the same opening / closing device.

As shown in the figure, the tableware dryer of the present invention is of a warm air type, the tableware dryer main body 11, a cover 12 mounted on the main body 11 so as to be openable and closable, the main body 11 and the cover. A drying chamber 13 formed by 12 and a warm air generator 15 for heating the air from the air inlet 14 of the main body 11 to send warm air to the drying chamber 13, and the air sucked into the air inlet 14. An odor filter 16 for deodorizing and an opening / closing device 50 for opening the exhaust port 25 are provided.

The dryer main body 11 has a space 11h formed therein by a box 11a having an upper opening and an upper plate 11b covering the upper opening of the box 11a. The space 11h is formed in the center of the upper plate 11b. The air outlet 11d which communicates with the drying chamber 13 is opened.

A plurality of the intake ports 14 are formed in the front portion of the bottom wall of the main body 11.

In the space 11h, an air guide tube 11f forming an L-shaped air guide path 11e is arranged from the rear lower part 11c to the central outlet 11d of the upper plate 11b.

A vent hole 11g is formed on the upper surface of the rear lower part 11c side of the air guide tube 11f to allow air from the intake port 14 to be temporarily diverted around the air guide tube 11f and taken into the air guide path 11e. It is set up.

The legs 17 are attached to the four corners of the bottom wall of the box body 11 a of the main body 11.

The warm air generator 15 provided in the tableware dryer main body 11 is arranged in the air guide tube 11f and has a suction unit 26 for sucking the outside air from the intake port 14 into the air guide passage 11e. , A heater 27 as a heating unit in the air guide tube for heating the sucked air.

The suction part 26 is composed of a sirocco fan 28 arranged near the ventilation port 11g, and a motor 31 outside the air guide tube for rotating the fan 28.

The odor filter 16 is detachably attached to an outlet formed on the front surface of the main body 11 so as to correspond to the intake port 14, and deodorizes passing air.

The flow dividing plate 41 installed above the air outlet 11d in the center of the main body 11 uniformly divides the warm air from the air outlet 11d into the drying chamber 13, and the upper portion of the flow dividing plate 41. Has a placing plate 42 for placing tableware. The cover 12 at the upper part of the plate 42 is a half-open type which is formed in a hemispherical shape and whose central part is divided into two parts. The front cover part 23 and the rear cover part 23 each have an arcuate cross section. 24 and is installed on the upper surface plate 11b. The front cover portion 23 is rotatably supported around the support shaft 5 (see FIG. 5) of the main body 11, and the rear cover portion 24 is fixed to the main body 11. An exhaust port 25 is formed at the upper end of the front cover part 23 for exhausting warm air that has absorbed moisture in the drying chamber 13. An opening / closing device 50 is provided below the exhaust port 25. As shown in FIG. 2, the device 50 has a number of exhaust ports 25 below the exhaust port 25 in order to open and close the exhaust port 25. The combined exhaust port cover 53 is adhered to the sliding guide 54 so as to be located between the sliding guide 54 and the front cover 23, and the end of the exhaust port cover 53 provided at the end of the sliding guide 54 shrinks at high temperature. A shape memory alloy spring 51 that remembers the shape is joined, and a non-shape memory alloy spring 52 is joined to the end of the exhaust port cover 53 on the opposite side of the sliding guide 54. The motion guide 54 is configured to slide.

That is, the shape memory alloy spring 51 contracts due to its properties when the temperature of the drying chamber 13 rises to around 40 to 45 ° C., and the attractive force of the shape memory alloy 51 becomes smaller than that of the non-shape memory alloy 52. In order to excel, the sliding guide 54 is pulled and slid in the direction of the arrow to open the exhaust port 25. On the contrary, when the temperature drops to around 45 to 40 ° C., the shape memory alloy spring 51 returns and at the same time is pulled in the direction opposite to the arrow by the attractive force of the non-shape memory alloy spring 52 and slides. The guide 54 slides and the exhaust port 25 is closed. Further, the exhaust port 25 is closed at room temperature.

FIG. 3 is a temperature characteristic diagram showing the temperature change of the position of the exhaust port cover 53. The exhaust port cover 53 has a shape memory alloy spring 51 between AB, that is, 6 to 10 minutes after the start of energization. And the exhaust port 25 is opened.

The exhaust port cover 53 is attracted by the attraction force of the spring 52 made of a non-shape memory alloy between CDs, that is, 5 to 25 minutes after the energization is stopped, and the exhaust port 25 is closed.

In the above configuration, when the tableware dryer is used, the front cover portion 23 is rotated upward to open the front surface of the drying chamber 13, and the tableware is placed on the placing plate 42 installed in the drying chamber 13. Place and close the front cover part 23.

Next, the switch of the operation panel on the front surface of the main body 11 is turned on, the motor 31 of the warm air generator 15 is operated to rotate the fan 28, and the outside air is guided from the intake port 14 to the air guide passage 11 e.

At this time, the air that has passed through the odor filter 16 from the intake port 14 is deodorized by the deodorant, and fine dust is also removed.

Then, the heater of the heating unit 27 is operated to heat the air in the air guide passage 11e, and hot air is blown into the drying chamber 13 from the air outlet 11d to dry the dishes. The hot air containing dried water and containing water has a high temperature in the vicinity of the opening / closing device 50, and therefore the exhaust port 25 is in an open state. Therefore, the hot air containing water is discharged from the port 25 to the outside. Be done.

When the drying of the tableware is completed and the heater of the heating unit 27 is stopped, the temperature in the drying chamber 13 is gradually lowered, and the switchgear 50 also reacts accordingly and the exhaust port cover 53 is not closed. Since the exhaust port 25 is closed by returning by the attractive force of the shape memory alloy spring 52, it is possible to prevent floating dust from entering the drying chamber 13, which is sanitary.

As another embodiment, as shown in FIG. 4, one end of a bidirectional shape memory alloy plate 55 is bonded to the upper portion of the exhaust port 25 of the front cover 23, and when the temperature rises, the plate 55 is bonded. The unopened side bends upward and opens the exhaust port, and when the temperature drops, it closes the return state, that is, the exhaust port, and prevents the entry of floating dust.

It should be noted that the spring 51 of the shape memory alloy or the bidirectional shape memory alloy plate is energized to slide the exhaust port cover 53 only when it is dried, and the bidirectional shape memory alloy plate is bent to open the exhaust port 25. It may be allowed to.

[Effect of the device]

 As is clear from the above description, according to the present invention, the opening / closing device is provided at the exhaust port of the main body, and the exhaust port is opened only when drying is detected by sensing the temperature of the drying chamber. Since the exhaust port is closed when not in use, floating dust does not enter and does not adhere to cleaned dishes.
