Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating device for a rotary dining table for providing food while keeping the temperature in a rotary dining table using a crescent chain.

2. Description of the Related Art A number of restaurants have appeared in which a crescent chain is run on a counter in a forward direction to form a rotary dining table, and various foods conveyed on the crescent chain are selected and provided for eating and drinking.

In a restaurant with such a configuration, since the product may be transported on the crescent chain for a long time without being selected by the customer, as a product, after adjustment,
Things that change in flavor in a short time are inappropriate, and sushi is currently the mainstream.

Problems to be Solved by the Invention Therefore, according to the conventional technique, it is difficult to provide products other than sushi, for example, products that require heat retention, such as dumplings and sweet potatoes. There was a problem. As these products cool down while being conveyed forward, the flavor is remarkably reduced,
This is because there is no heat retaining means that can effectively keep the goods on the traveling crescent chain in the conventional rotary dining table where some heat retaining means is required.

Therefore, an object of the present invention is to provide a warming device for a rotating dining table that can effectively keep warm the products on a traveling crescent chain in view of the situation of the related art.

Another object of the present invention is not only to simply apply heat to a product, but also to apply a suitable amount of moisture to prevent the product from drying and maintain a more favorable flavor. An object of the present invention is to provide a heating apparatus for a dining table.

Means for Solving the Problems The structure of the present invention for achieving the above object includes a crescent chain, a boiler, a pedestal, and a steam pipe, and the crescent chain runs forward on the upper surface of the counter, and the boiler Moves with the crescent chain,
The cradle rests on the top of the crescent chain, while the steam pipe has one end communicating with the boiler and the other end opening on the top of the cradle via an on-off valve. The gist is that the on-off valve opens and closes depending on the presence or absence.

A duct device having a ventilation fan may be provided above the crescent chain.

According to this configuration, when the product tray is placed on the receiving tray, the on-off valve opens, so that steam from the boiler blows out to the upper surface of the receiving tray via the steam pipe to keep the product warm. Can be done. Here, the boiler moves together with the crescent chain by the forward running of the crescent chain, so the products conveyed by the crescent chain are:
During the transport, it is possible to keep the temperature continuously.

Further, if a duct device having a ventilation fan is disposed above the crescent chain, the steam used for keeping the product warm can be discharged to the outside, so that there is no possibility that steam is trapped in the store.

 It works as described above.

Embodiments Hereinafter, embodiments will be described with reference to the drawings.

Is disposed at a corner of the traveling path of the crescent chain 10, and a motor 16 By driving the sprocket 15 via the drive chain 16a and the drive chain 16a, the crescent chain 10 is driven to travel.

The boiler 20 has a boiler main body 22 suspended from a lower surface of an arbitrary slat 11 of the crescent chain 10 via a steam pipe 21 (FIGS. 2 and 1). Each outer surface is provided with a heat insulating material 20a. Boiler body 2
2, an electric heater 23, a water level gauge 24, and a temperature detector 25 are incorporated, and a safety valve 26 is provided.

Trolley devices 23a, 23a are provided on the upper surface of the boiler main body 22, and slide from the structural material C1 of the counter C via the arms C2 to the trolley wires 23b, 23b. However, trolley wires 23b and 23b are crescent chains
It is assumed that the counter C is electrically insulated from the counter C by an insulating material (not shown). The trolley devices 23a and 23a are connected to the electric heater 23 via a controller (not shown), and the trolley wires 23b and 23b are connected to an external product power supply AC. Here, the controller uses the output of the temperature detector 25 to control the energization of the electric heater 23 in accordance with the temperature of the water W in the boiler 20.
It is assumed that the output of 24 prevents the boiler 20 from being idled.

The cradle 30 is a circular pedestal placed on the upper surface of the crescent chain 10 using the pins 13 of the crescent chain 10, and the inside thereof is filled with a heat insulating material 30a. A steam pipe 21 is open in the section. While one end of the steam pipe 21 communicates with the upper part of the boiler 20,
The other end is a bent short tube that opens on the upper surface of the cradle 30,
The opening / closing valve 21a is attached to the end of the
Figure). That is, the on-off valve 21a is constantly urged upward by the spring 21b so that a part thereof projects upward from the upper end surface of the steam pipe 21 at the same height as the upper surface of the receiving table 30, and the steam pipe 21
Can be closed while the product tray S is placed on the receiving tray 30 so that when the steam pipe 21 is pushed down,
Can be opened (two-dot chain line in the figure).

The cradle 30 is provided with a lamp display 31 (FIG. 1). The lamp indicator 31 is turned on when the controller detects that the amount of water in the boiler 20 is sufficient, and is turned off when the amount of water is insufficient.

A product dish S can be placed on the upper surface of the cradle 30. The product dish S fits on the upper surface of the receiving table 30, and when steam is blown upward through the hole S1 on the bottom face, the product S3 on the mesh dish S2, via the mesh dish S2, The steam can be applied.

Above the counter C, a duct device CD including a ventilation fan F and an illumination lamp FL is provided. However, the duct device CD is provided with a duct hole CDa that opens downward almost right above the traveling route of the crescent chain 10, and the duct hole CDa is communicated to the outside via a ventilation fan F.

Now, if the boiler main body 22 of the boiler 20 is filled with water W and the electric heater 23 is energized through the trolley wires 23b and 23b and the trolley devices 23a and 23a, the crescent chain 10 is traveling forward. Also, steam can be produced by the boiler 20. When the product tray S is not placed on the receiving tray 30, this steam is sealed in the boiler 20 and does not blow upward because the on-off valve 21a is closed.

When the product tray S is placed on the cradle 30, the on-off valve 21a is opened, so that the steam from the boiler 20 blows out above the cradle 30 and rises via the net tray S2 of the product tray S. From, a dish
Products S3, S3 ... on S2 can be well kept warm. That is, the products S3, S3,... Can be continuously kept warm by steam even during the forward conveyance by the crescent chain 10, so that the flavor can be prevented from being lowered.

On the other hand, the steam rising above the products S3, S3... Is discharged to the outside by the ventilation fan F through the duct hole CDa opened above the counter C, so that steam can be trapped in the store. There is no possibility that the surroundings will be excessively wet.

Other Embodiments The on-off valve 21a can have another configuration. For example, the presence or absence of the commodity dish S is detected by an electric sensor,
It is also possible to change to a solenoid valve that operates by an output signal from this sensor.

The boiler 20 is suspended from the slats 11 of the crescent chain 10 via the steam pipe 21. Alternatively, the boiler 20 may be suspended using the pins 13 of the crescent chain 10.

In addition, guide rails G, G for supporting the weight of the boiler 20 are incorporated in the counter C (FIG. 6).
The boiler 20 may be provided with casters 20b, 20b, connected to the crescent chain 10 via a connecting member 27, and may be moved by being pulled by the crescent chain 10. At this time, it is necessary to use a flexible material for both the connecting member 27 and the steam pipe 21 so that the crescent chain 10 can be bent.

Further, the trolley devices 23a, 23a in each of the above-described embodiments.
Of course, the trolley wires 23b and 23b may be provided not only on the upper surface of the boiler 20, but also on the side surface or the lower surface thereof (FIG. 6).

Effect of the Invention As described above, according to the present invention, a boiler that moves together with a crescent chain is provided, and steam from the boiler is ejected to the upper surface of a cradle on the crescent chain via a steam pipe. The steam pipe is equipped with an open / close valve that opens and closes depending on the presence or absence of the product tray on the tray, so that the products on the product tray can be continuously conveyed by steam from the boiler while being transported forward by the crescent chain. Because it can be heated and kept warm, there is an excellent effect that it can be conveniently used for providing products that require keeping warm. In addition, since the heating at this time uses steam, the product is extremely dried,
There is no fear that the flavor of the product is deteriorated.

In addition, if a duct device with a ventilation fan is arranged above the crescent chain, the steam used to heat the product may be trapped in the store, and the surrounding environment such as the counter may become excessively wet. This has the effect of effectively preventing the risk of the occurrence.
