Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic bread maker that can produce freshly baked bread at a desired time by inputting predetermined materials.

Conventional technology When baking bread at home, we generally use equipment such as a kneading machine, fermentation machine, stretching rod, and oven, but it is very difficult to control the temperature and time, so the bread is delicious regardless of the time of the year. Making freshly baked bread required considerable skill. In order to solve these problems, we have created a bread maker with a configuration in which the kneading function, fermentation function, and oven function are housed in a single product, as shown in Figure 8.
An automatic bread maker that automatically bakes bread by setting a timer as shown in FIG. 9 has been proposed.

The configuration shown in FIG. 8 has a cooking chamber 2 inside the main body 1.
The heater 3 is provided in the upper and lower parts of the cooking chamber 2, and the lower part of the front cooking chamber is equipped with a kneading blade 5 that is driven at a reduced speed by a motor 4 and a kneading container 6 that is detachably attached. After kneading and fermenting the ingredients in the kneading container 6, the user takes out the kneading container 6, performs "degassing" and "shaping" operations, transfers it to a bread baking mold (not shown), and transfers it to the pre-cooking chamber 2. It is placed inside and used as an oven for shaping, fermentation, and baking.

In the device shown in FIG. 9, a frame 8 is provided inside a main body 7, and a motor 9 and a heating tank 12 equipped with a heater 10 and a heat insulating material 11 on the outer periphery are fixed to the frame 8. A bread baking mold 14 having blades 13 is removably attached and is driven to reduce speed by a belt 15 and a pulley 16. Further, a lid 19 having a top plate 17 and steam holes 18 is fitted into the heating tank 12, and covers the heating tank 12 and the bread baking mold 14. 20 is a timer, temperature control, and power control circuit. Further, the temperature sensor 21 is connected to the heating tank 1
It is fixed to the outer surface of 2. With this configuration, when ingredients are put into the bread baking mold 14 and a timer is set, operation starts at a predetermined time, each process is automated by the timer and temperature control, and the bread is baked at a predetermined time.

Problems to be Solved by the Invention In such a conventional configuration, in the former case, kneading and fermentation are automatically performed by setting a timer;
Once fermentation is complete, take it out of the oven, manually ``vent gas'' and ``shape'' it, and then move it to cooking chamber 2.
For example, in the morning, to carry out shaping fermentation and firing.
If you want to eat freshly baked bread, there is a problem in that you have to wake up early in the morning and do the preparation work. Furthermore, since the former is not a dedicated bread baking machine, it requires unnecessary electricity and also has the problem of the outer surface of the main body becoming hot enough to cause burns.

In the latter case, the material is put in and the timer 2
If the setting is 0, the bread will be baked automatically, but since the heater 10 is installed on the outer circumferential surface of the heating tank 12, the temperature of the side wall of the main body 7 facing the heating tank 12 rises, and the top of the heating tank 12 rises. There was a problem that the temperature on the plate side was low and the top surface of the bread was not browned.

In view of the above-mentioned problems, the present invention provides an automatic bread maker that prevents the temperature rise of various devices within the main body with a simple structure.

Means for Solving the Problems In order to solve these problems, the present invention has a configuration in which a heater is installed inside the cooking chamber, and a gap is provided between the outer periphery of the upper end of the cooking chamber and the main body.

Function: With the above configuration, the hot air generated near the cooking chamber inside the main body during bread baking is dissipated to the outside of the main body, and the temperature rise of various devices built into the main body is prevented without the need for any special mechanism.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 7. In the figure, 30 is a main body, 31 is a chassis provided within the main body 30, and a motor 32 is fixed to this chassis 31. At one end of the shaft of the motor 32,

Inside the cooking chamber 38, there is a bread baking mold 41 having a removable kneading blade 40 on the inner bottom, and a blade shaft 43 and an upper connector 44 are pivoted on a bread mold base 42 fixed to the bottom of the bread baking mold 41. has been done.

Furthermore, the bread baking mold 41 is removably fitted into a pulley bearing stand 39 which pivotally supports the large pulley 36, pulley shaft 45, and lower connector 46, and which is fixed to the shearge 31. Furthermore, an elastically supported temperature sensing portion 47 protrudes from the side surface of the cooking chamber 38 and is pressed against the side surface of the bread baking mold 41 .

In addition, a step portion 48 having a flat surface over the entire circumference is provided at the upper part of the cooking chamber 38, and a gap portion 4 is provided between the upper end outer peripheral surface and the main body over almost the entire circumference.
There are 9.

The upper surface of the cooking chamber 38 has a lid 50 that can be opened and closed, a mounting shaft 51 protruding from the center of the lower surface of the lid 50, and an inner lid 54 that is elastically supported by a presser spring 52 and a presser plate 53. When the body 50 is closed, the lower surface of the outer periphery of the inner lid 54 is brought into pressure contact with the plane of the upper step 48 of the cooking chamber 38. And the second
As shown in FIGS. 5 to 5, the cooking chamber 38 is fixed to the main body with a fixing member 55 made of a heat-resistant nonmetallic material with poor thermal conductivity. Except for the portion where the fixing member 55 is located, the outer circumferential portion of the upper end of the cooking chamber 38 has a gap portion 49 between the main body 30 and the entire circumference.

The lid 50 is provided with an opening knob 56 and a latch 57 for opening the lid 50.
Further, a pin shaft 58 is provided on the small pulley 34 side of the motor shaft at a position slightly eccentric to the motor axis, and a reciprocating pump 59 configured to vibrate an elastic membrane absorption such as rubber is attached to the side of the chassis 31. The pump side pin shaft 60 is located at the peak of the elastic membrane absorption.
is fixed and connected to a pin shaft 58 and a connecting rod 61. Furthermore, the discharge pipe 6 of the reciprocating pump 59
2 is a water tank 6 attached to the main body 30
3, and a water supply pipe 64 further communicates with a water supply port 65 which is opened so that water can be sprayed onto the bread baking mold 41 in the cooking chamber 38.

Further, 66 is a switch panel for inputting settings such as baking time. Further, 67 is based on the input information of the switch panel and the input information of the temperature detection section 47.

This is a control device for output.

Next, the operation of the present invention will be explained.

A bread baking mold 41 and a kneading board 40 are installed in the cooking chamber 38.
and add flour and other ingredients. Lid body 5
0, fill the water tank 63 with a predetermined amount of water, and close the cap (not shown) to seal it. In this state, the baking time of the bread is inputted from the switch panel 66, and when the predetermined time comes, the motor 32 starts operating and kneading is performed. At this time, at the same time, a pin shaft 58 eccentrically provided on the shaft of the motor rotates, causing the reciprocating pump 59 to vibrate, thereby sending air out from the discharge pipe 62. And water tank 6
3, water is supplied into the bread baking mold 41 from the water supply port 65 through the water supply pipe 64, and is kneaded with ingredients such as flour by the kneading blades 40. After the kneading is completed, based on the process control of the control device 67, each step of primary fermentation, degassing, molding fermentation, and baking is performed while inputting information from the temperature detection unit 47 and adjusting the temperature of the bread baking mold 41 with the heater 37. Bread is baked automatically at the set time.

During this baking process, the cooking chamber 38 becomes the hottest, with some parts reaching temperatures of around 300°C. As a result, the temperature inside the main body 30 naturally rises, and the temperature of other parts and devices built into the main body also rises, which has an adverse effect, so it is necessary to release the hot air generated inside the main body 30. A gap 49 formed at the outer periphery of the upper end of the cooking chamber 38 functions to release this hot air to the outside, thereby preventing a rise in temperature within the main body. Furthermore, the fixing member 55 shown in FIGS. 5 and 6 is shown in a state in which a protrusion 68 is provided on the side surface and is fitted into a rib 69 of the main body 30 using elasticity. By doing so, the fixing member 55 can be easily fixed without using screws or the like.

FIG. 7 shows an embodiment in which the main body 30' and the fixing member 55' are fixed with screws.

Effects of the Invention As described above, according to the present invention, by providing a gap at the outer periphery of the upper end of the cooking chamber, it is possible to obtain the effect of preventing a temperature rise inside the main body with almost no effect on the inside of the cooking chamber. The main body does not need to be made of a metal material unlike a thermal device having an oven function, and the main body can be constructed from a relatively inexpensive resin material.
