Description

[Detailed description of the invention] This invention relates to a cooking device that heats an object by injecting steam onto it, a so-called steam oven.The purpose of this invention is to efficiently collect water generated after steam injection into a water receiver. It is something.

The heating chamber of conventional steam ovens is coated with silicone putty or seam welded to prevent water from leaking from the joint between the roughly U-shaped bottom plate and back plate that make up the heating chamber during steam injection. Methods such as curling or overlapping the bottom plate and the back plate have been used.

These methods include, for example, as shown in FIG.
In addition, in the case of a so-called hot air circulation type cooker that increases the temperature of the air in the heating chamber 1 by installing a circulation fan 5 that circulates the air in the heating chamber 1 and the compartment 3, the circulation fan 5 and the heater 4 are installed once. The drawback was that it could not be removed.

This is particularly true in the case of a steam oven equipped with a high-frequency heating device, since if the circulation fan 5 is inserted directly into the heating chamber 1, high-frequency waves will leak from the drive shaft 6 of the circulation fan 5, so it is necessary to provide a separate chamber.

The present invention solves the above-mentioned conventional drawbacks, and an embodiment of the present invention will be described below with reference to the drawings.

A power feed port 9 is provided on the ceiling plate of the heating chamber 1 for radiating high frequency waves generated by the magnetron 7 into the heating chamber 1 via a waveguide 8.

A recess 10 is provided in the bottom plate of the heating chamber, and an exhaust hole 11 is formed approximately in the center of the recess 10 to discharge water adhering to the walls of the heating chamber.

As described above, the compartment 3 is formed at the rear of the heating chamber, and the circulation fan 5 is rotated by the motor 12.

When the circulation fan 5 is rotated, air heated by the heater 4 enters the heating chamber through the upper and lower air outlets 13, returns to the compartment 3 through the central suction opening 14, and cooks the object to be heated.

This heating chamber is composed of a front mounting plate, a substantially U-shaped bottom plate and side plates, a back plate 2, and a ceiling plate. When steam is injected, water leaks from the heating chamber bottom plate, front plate, and back plate 2.
from the junction with.

The present invention relates to the joint between the bottom plate and the back plate, and as shown in the figure, a gutter 15 is fixed to the extension of the bottom plate of the heating chamber, and a notch 16 is provided in the center thereof through which water drips.

The water dripping from the gutter 15 and the water dripping from the discharge hole 11 provided in the bottom plate 4 of the heating chamber fall onto the inspection window 18 screwed to the bottom plate 17 of the main body, and the water drips from the groove 1 provided on the inspection window 18.
The water flows through part 9 and enters the water receiver 21 through the discharge hole 20.

In addition, by providing an inspection window 18 on the bottom plate 17 of the main body, and providing a groove 19 in the inspection window that communicates the gutter 15 and the water receiver 21, the furnace window can be removed and washed, making it clean. For example, as shown in FIG. 3, when a magnet-driven turntable 33 is installed at the bottom of the heating chamber, removing the rotating body 26 that drives the turntable 33 and replacing the belt 27 can be done by removing the inspection window 18. It can be done easily.

In the rotation mechanism, when a pulley 29 is rotated by a motor 28, a rotating body is rotated by a belt 27.

Since a magnet 30 is attached to the rotating body 26, the magnet B31 of the turntable 33 is attracted, and as the roller 32 rotates along the recess 10 of the heating chamber bottom plate, the saucer 34 also rotates.

The shaft 35 of the rotating body 26 is hollow so that water can fall onto the groove of the inspection window 18.

In addition, since the socket 36 of the water tray 21 can be brought forward, after water has accumulated in the water tray 21, the water tray 21 can be erected and the handle can be raised, making it easy to use.

Furthermore, a circulation fan 5 is installed in the heater case 23 that constitutes the compartment 3.
．． A motor 4 and the like are provided, and are attached to the ceiling plate and the bottom plate of the heating chamber via the back plate 2 with screws 24, but even if water leaks from these joints, it will drip into the groove 19 through the groove 15. , water does not accumulate on the bottom plate of the heating chamber, and the heater case 23 and the heater 4 attached to the heater case are protected. This is convenient in terms of after-sales service, as the circulation fan 5 and the like can be easily removed.

Furthermore, the supports 25 at the rear of the heating chamber are attached to the left and right flanges, which reduces heat loss during hot air circulation.

As is clear from the above explanation, the bottom plate and back plate 2 of the heating chamber
A gutter is provided on the outside of the joint, and the gutter communicates with the water receptacle, resulting in the following effects.

(1) Even if water leaks from the joint between the bottom plate of the heating chamber and the back plate, it will collect in the water receiver provided at the bottom of the main unit, so it is not only clean, but also allows easy replacement of heaters, fans, etc. can.

(2) Compared to conventional cookers, the bottom plate of the heating chamber requires only sheet metal processing, so workability is good and large equipment is not required.
