Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a bread making machine that automatically performs a series of steps of kneading, fermentation, and baking by inputting bread ingredients and bakes bread at a predetermined time. It is.

BACKGROUND TECHNOLOGY 2 Page Generally, there are many factors that ensure the reliable production of bread, one of which is the removal of steam after baking. In other words, if this steam release is not done properly, condensation will occur on the finished bread, resulting in sticky bread and a shrunken appearance, making it difficult to achieve fluffy and delicious bread. I can't make it. Therefore, it can be recognized that the steam release is a very important final step in bread manufacturing.

The most effective means of removing steam is to forcefully ventilate the firing chamber after firing. FIGS. 4 to 6 show a conventional bread making machine, in which a baking chamber 3 has a heating means 1 such as a heater, and has an upper opening that can be opened and closed with a lid 2.
A firing case 6 is detachably equipped with a kneading means 4 such as a blade, and the firing chamber 3 is further provided with an exhaust hole 10 for discharging steam inside the firing chamber 3. An exhaust passage 6 is provided, and an intake passage 7 with a thank you note is formed in the lid 2. Further, a heat shield plate 9 is installed on the outside of the baking chamber 3. Soshi 3 lX-
> The inside of the firing chamber 3 is ventilated by forcibly discharging steam from the inside of the firing chamber 3 by driving a fan 8 interposed in the exhaust passage 6.

The exhaust passage 6 is attached by passing the opening of the exhaust passage 6 through the hole 11 of the heat shield plate 9, inserting it into the exhaust hole 10, and then pressing it against the heat shield plate 9 and caulking it.

Problems to be Solved by the Invention In the conventional bread making machine described above, the opening of the exhaust passage 6 is inserted into the exhaust hole 1o through the hole 11 of the heat shield plate 9, and is brought into pressure contact with the heat shield plate 9. Because it is caulked, during the firing process or the steam venting process, high-temperature air located in the space between the firing chamber 3 and the heat shield plate 9 and high-temperature steam inside the firing chamber 3 are released into the opening of the exhaust passage 6. There was a problem that leakage from the gap between the part 12 and the hole 11 of the heat shield plate 9 increased the temperature of the control circuit 130 component that controls time, temperature, etc., and the outer body 14 became hot.

The present invention solves these conventional problems, and seals the baking chamber and the exhaust path, as well as the heat shield and the exhaust path, thereby preventing the control circuit parts and the outer body from becoming hot during bread production. The purpose is to provide opportunities.

Means for Solving the Problems In order to solve the above problems, the bread making machine of the present invention has an elastic layer formed with a two-layer glue knob in pressure contact with the baking chamber and the heat shield plate at the connection part between the baking chamber and the exhaust passage. This is an arrangement of example seal portions having the following structure.

In the process of removing working steam, the steam inside the firing chamber is sucked in by a fan, and this steam is discharged to the outside through an exhaust passage. This series of passages has a connection part between the firing chamber and the exhaust passage, and a part where the exhaust passage passes through the heat shield plate placed around the outer periphery of the firing chamber, and gaps are created at each location, but in the present invention, In this method, an elastic sealing member made of two layers of adhesive is placed at the connection between the firing chamber and the exhaust path, the first layer of adhesive is brought into pressure contact with the firing chamber, and the second layer of adhesive is insulated from heat. Since it is pressed against the plate, each gap is sealed. As a result, the hot air in the space between the baking chamber and the heat shield plate and the steam passing through the exhaust path will not leak into the gap between the baking chamber and the heat shield, which will prevent the parts and body of the control circuit that controls the series of bread manufacturing processes. The outer shell does not get hot and is extremely safe.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 3.

In Fig. 1, heating means 2 consisting of an air-fuel mixture
The firing case 723 is detachably installed in the firing chamber 22 and has a bottomed cylindrical shape with an open upper part.
, and a handle 25 is provided above. The kneading means 24 are connected to a drive source via couplings 26,27. 28 is a temperature sensor that detects the temperature of the baking case 723 and controls the heating means 21, etc.; 31 is a control circuit that controls the heating means 21 and the like; 29 is a lid that opens and closes the upper opening of the baking chamber 22. , and is provided with an inner lid 30. 32 is a fuselage case.

Furthermore, the baking chamber 22 is equipped with a heat shield plate 33 on the outside. 3
4 is an exhaust path for exhausting steam in the firing chamber 22, and 6 is an exhaust path 34 connecting the vane with intake holes 36 at both ends. An exhaust hole 36 is formed. Further, a fan 37 for sucking steam is arranged in the center of the exhaust path 34. 38 is a morph for driving the fan 37. A sealing member 39 made of heat-resistant rubber or the like is attached to the intake hole 35 at the end of the exhaust path 34.
This sealing member 39 has a ring-shaped two-layer glue knob 40.
41 is formed. The glue knob 40 of the first layer passes through the hole 42 in the side wall of the heat shield plate 33 and comes into pressure contact with the side wall of the baking chamber 22, and the glue knob 41 of the second layer is positioned so as to come into pressure contact with the heat shield plate 33. ing. Note that one of the side walls of the firing chamber 22
A large number of small holes 43 are arranged inside the contact portion of the lip 40 of the layer.

In the above configuration, all steps of bread manufacturing will be briefly explained. First, bread ingredients such as flour, salt, sugar, butter, and water are put into the baking case 723. When the operation is started, the bread ingredients are kneaded, and after a certain period of time, Dry E 71- is mixed in and further kneaded. Next, move on to the fermentation process. When the fermentation process begins, guffing is carried out to knead at 7 cycles, and the first, second and third stages are mixed.
Next, shaping and fermentation proceed, followed by a firing process. Then, the bread is taken out of the baking case 723, placed on a net-like plate, and allowed to cool naturally, resulting in fluffy and delicious bread. However, if the bread is not taken out immediately after the baking process, dew condensation will occur inside the baking turf 23, resulting in sticky bread. A steam venting process is installed to ventilate the steam.

Now, when the baking process is completed, the motor 38 is driven, the fan 3 is rotated, and the steam in the baking chamber 22 begins to be sucked. The steam then passes through a small hole 43 in the side wall provided in the firing chamber 22, and passes through the intake hole 36. It is exhausted to the outside through the exhaust hole 36. In this case, in one embodiment of the present invention, the firing chamber 22
The first layer glue knob 40 is pressed against the side wall of the heat shield plate 3.
Since the lip 41 of the second layer is pressed into contact with the heat shield plate 33, the steam in the firing chamber 22 may leak into the space between the firing chamber 22 and the heat shield plate 33, and the hot air in the space may leak through the holes in the heat shield plate 33. 42 into the space within the fuselage turf 32. As a result, parts of the control circuit 31 and the fuselage case 73
2 will never reach high temperatures. Furthermore, even if the exhaust path 34 is slightly misaligned with respect to the firing chamber 22, the effect will not be impaired. Therefore, fluffy and delicious bread can be made without malfunctioning of the control circuit 31 or dangerous conditions such as burns.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
At the connection between the steam venting exhaust passage and the firing chamber, an elastic sealing member made of two layers of glass is placed in pressure contact with the firing chamber and the heat shield, so that the steam inside the firing chamber can be removed from the firing chamber. There is no possibility that steam leaking into the space between the chamber and the heat shield plate will leak into the space inside the fuselage case 7 through the holes in the heat shield plate, and as a result, the parts of the control circuit will not leak. and aircraft case 7
Since the bread does not reach high temperatures, it is possible to make fluffy and delicious bread without causing dangerous conditions such as control circuit malfunctions or burns.
