Description

[Detailed Description of the Invention] This invention relates to an oven humidifier, and more particularly, to an oven humidifier that is installed inside an oven for bread, sweets, pastries, etc., and supplies steam to dough for bread, etc.

It has been known that supplying steam to bake bread, confectionery, etc. can improve the baking effect of bread, but conventional methods of supplying steam have had drawbacks such as inferior steam generation efficiency and heating efficiency.

This idea includes a closed heater that is heated with a gas burner, a fan-shaped nozzle that connects to the water supply pipe and can spray mist over a wide area inside the heater, and a steam mound that can spray steam outside the heater. It is an object of the present invention to eliminate the above-mentioned drawbacks by providing a humidifier for an oven characterized by the following features:

Fig. 1 shows a plan view of an embodiment of this invention, Fig. 2 shows a cross section taken along line A-A in Fig. 1, and Fig. 3 shows a central cross section of an example of use in which the embodiment of this invention is installed in a reel oven. explain.

1 is a heater, which has a closed shape that can be heated. In this embodiment, the heater 1 is constructed by fixing a lid 3 onto a substantially rectangular plate 2 having a large heat capacity.
A plurality of grooves 16 are carved on the top surface of the plate.
It is also possible to provide wart-like protrusions or no grooves at all. Furthermore, grooves, wart-like protrusions, etc. may be provided on the lower surface of the plate 2 to increase the heat receiving area. 4 is a spray nozzle, and in this embodiment, five spray nozzles are attached to the long side of the heater 1 at appropriate intervals.
Although the spray nozzle 4 is a fan-shaped nozzle in this embodiment, it may be a simple opening, and can spray mist water into the heater 1 in a wide-angle fan shape, and communicates with the water supply pipe 5. Reference numeral 6 denotes a steam injection port, which is formed on the opposite side of the spray port 4 by narrowing the heater 1 . The steam outlet 6 may be located on the opposite side of the spray outlet 4 or at any other appropriate position. In this embodiment, the steam injection port 6 is connected to the heater 1
It consists of 10 nozzle shapes protruding from the base, but it may also consist of slit shapes, etc. 7 is a gas burner that heats the plate 2. In this embodiment, the plate 2 is heated by the gas burner 7, but it may be heated by a known heat source such as an electric heater. Steam injection port 6
The longer the length, the farther the tip of the steam injection port is from the gas burner 7, which is desirable in order to avoid the influence of the gas burner 7. In this embodiment, the length of the steam injection port 6 is approximately twice the width of the heater 1. In order to avoid the influence of the gas burner 7, the tip of the steam injection port may be bent upward or downward.

Gas burner 7 is connected to gas main 8 and heater 1
An appropriate number of plates are installed at the bottom of the plate 2 to heat the plate.
Reference numeral 9 denotes an oven in which this embodiment is installed in the lower part of the interior, and in this usage example, it consists of a reel oven. Top heater 1 is installed on the ceiling inside oven 9.
has 0. Between the heater 1 and the top heater 10 are six rotatable trays 11 and a tray 11.
It has a stabilizer link 12 that can be interlocked with. 13 is an air curtain, 14 is an access door, and 15 is an exhaust hole.

Therefore, water is supplied to the spray nozzle 4 through the water supply pipe 5, and the water is sprayed from the spray nozzle 4 into the heater 1 in the form of a mist and a wide-angle fan shape. On the other hand, the gas burner 7 heats the plate 2, and the plate 2 and the gas burner 7 heat the air in the oven 9, thereby heating the bread, confectionery, etc. placed on the tray 11. Bread, sweets, etc. are heated by heating the air inside the oven 9 using the plate 2 and the gas burner 7, so the flame does not directly hit the product, and at the same time, the heated plate 2 instantly sprays water in the form of a mist. It is possible to use steam. Even if there is moisture that remains on the plate 2 without being vaporized, the moisture accumulates in the grooves 16 of the plate 2 and is heated by the plate 2 and vaporized. Moisture that is not vaporized is discharged to the outside through the groove 16.
The generated steam is sent from the steam injection port 6 to the oven 9.
It is ejected into the air and supplied to the surface of the dough of bread, confectionery, etc. together with the steam generated during combustion in the gas burner 7, thereby producing soft bread with a thin skin. At the same time, the tray 11 is rotating, and the top heater 1
By heating in Step 2, the coloring of the product is completed. Therefore, it is possible to provide an oven humidifier with high steam generation efficiency and high heating efficiency.
