Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oven equipped with a steam generator for baking various breads and confectioneries, and a steam generator used in the oven.

[0002]

2. Description of the Related Art When baking so-called solid bread such as French bread and German bread, it is necessary to supply steam into the baking chamber in order to improve the luster and texture of the baked product. For this reason, a steam generator is provided in the oven for baking the solid bread. As an oven equipped with a steam generator, for example, there are those disclosed in Japanese Patent Publication No. 1-31090 and Japanese Patent Publication No. 2-28046. Since the steam generator uses the ambient heat of the firing chamber as a heat source, it is placed near the ceiling surface of the firing chamber where a sufficient amount of heat can be obtained, that is, above the upper fire burner in the gas oven and above the upper heater in the electric oven. ing. Further, a water pipe for supplying water is introduced into the steam generator from the outside along the inside of the side wall of the oven.

[0003]

However, the oven provided with the conventional steam generator as described above has the following problems. (A) Since the water pipe is introduced along the inside of the side wall of the oven, the water pipe passes near various control devices attached to various parts of the side wall. Therefore, when water leaks from the water pipe, electrical and mechanical failure of the control device is likely to occur.

(B) Since the steam generator has a structure in which water is evaporated on a hot plate heated to a high temperature to generate steam, impurities contained in water remain and adhere to the surface of the hot plate, causing charring. As a result, it is necessary to regularly clean the inside of the steam generator. However, in the conventional oven, in order to remove the steam generator, the worker needs to enter the firing chamber and remove the upper heat burner, the upper heat heater, and the auxiliary parts such as the baffle plate and the heat storage plate. Must also attach them as in the original. This requires a great deal of time and labor to perform maintenance on the steam generator or its vicinity, such as cleaning the steam generator, resulting in poor work efficiency.

(C) Due to the above-mentioned structure, the conventional oven is manufactured after confirming the specifications as to whether or not the steam generator is provided. Therefore, if the specifications were changed after the parts related to the presence or absence of the steam generator were installed or processed, it was necessary to rebuild the area around the steam generator or manufacture a new product. Therefore, it is difficult to stock a fixed number of products as is normally done in the manufacturing industry, and planned production cannot be performed.

[0006]

The object of the present invention is to solve the above problems.
For various control devices attached to the inside of the side wall of the oven,
An object of the present invention is to provide an oven equipped with a steam generator in which a failure due to water leakage of a water pipe introduced into the steam generator does not occur. Another object is to facilitate maintenance of the steam generator or its vicinity, such as cleaning the inside. Further, it is another object of the present invention to enable planned production by enabling manufacturing without being affected by a specification change regarding the presence or absence of a steam generator during manufacturing of an oven.

[0007]

[Means for Achieving the Object] The means of the present invention for achieving the above object are as follows. The first means is an oven provided with a steam generator, which is provided on the steam generator and a side wall near the ceiling in the firing chamber or in the vicinity of the side wall. A mounting means for mounting, and a detachably provided in the front opening of the firing chamber corresponding to the position of this mounting means, the water pipe of the steam generator is insertable, and by removing the steam generator of the steam generator An oven provided with a steam generator, which includes a closing member adapted to be attached and detached from the front side.

In the second means, the mounting means is an oven provided with the steam generator according to the first means, which is a rail member that is attachable and detachable while sliding the steam generator.

A third means is a steam generator for use in an oven equipped with the steam generator according to the first or second means, wherein the steam generator is a heated hot plate. A steam generator for use in an oven, which includes a steam generating part that generates steam by sprinkling water and a water pipe introduced into this steam generating part, and the water pipe is led to the front side of the steam generator. Is.

[0010]

The water pipe of the steam generator is led out of the firing chamber through the closing member on the front side of the oven. Since the front wall of the oven is not normally provided with the control device, even if water leaks from the water pipe, the failure of the control device due to this does not occur.

During maintenance of the steam generator or its vicinity, such as cleaning the inside, by removing the closing member, various maintenance work including attachment / detachment of the steam generator can be performed from the open portion. Since the steam generator has a structure that can be easily attached and detached from the front side of the oven as needed, the steam generator is not included in the manufacturing process of the oven unlike the manufacturing of an oven equipped with a conventional steam generator. The process of assembling is not always necessary, and even if the specification changes regarding the presence or absence of the steam generator during the manufacturing, it does not affect the manufacturing.
