DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic bread maker that can make fresh bread at home.

Conventional technology When making bread at home, equipment such as a kneading machine, fermenter, rolling pin, and oven are generally used, but it is extremely difficult to control the temperature and time, and bread is delicious regardless of the season. Making freshly baked bread required considerable skill. In order to solve these problems, the inventors have proposed a device as shown in FIG. 2 that automatically bakes bread simply by setting the time. This configuration will be explained below.
1 is a main body case, 2 is a chassis provided in the main body case 1, and this chassis 2 has a motor 3.
A baking chamber 6 equipped with a lower heater 4 and a heat insulating material 5 on the outer periphery is fixed, and a bread baking mold 8 having a kneading blade 7 is installed inside the baking chamber 6, and the kneading blade 7 is driven by a belt 9 by a motor 3. and is decelerated and driven via pulleys 10 and 11. Furthermore, a motor cooling fan 3a is provided at the other end of the motor 3. Firing chamber 6

A solenoid 17 is installed to supply water to the tank. Reference numeral 18 denotes a control section that controls the motor 3, heaters 4 and 12, solenoid 17, etc., and performs control based on input information from a temperature detection section 19 that is in contact with the bread baking mold 8. With this configuration, when ingredients are put into the bread baking mold 8 and the baking time is set, operation starts at a predetermined time and the bread is baked.

Problems to be Solved by the Invention In such a configuration, a temperature detection unit that comes into contact with the bread baking mold measures the temperature of the bread baking mold (that is, the temperature of the bread dough), and provides this temperature as input information to the control unit 18. 19 through the heat insulating material 5, it receives heat from the motor 3 and warm air from the motor cooling fan 3a, and becomes higher than the actual temperature of the bread baking mold 8, and the control unit reports the correct information. 18, and as a result, good bread cannot be made.

In addition, especially when the outside temperature is low, the temperature difference becomes large, so the difference with the actual dough temperature becomes even more pronounced.

Means for Solving the Problems In order to solve these problems, the present invention has the following features:
A bread baking mold is disposed between the temperature sensing portion and the motor, and the temperature sensing portion is brought into contact with the bread baking mold.

Effect With the above configuration, there is no need to worry about the heat of the motor or motor cooling fan being transferred directly to the temperature detection part, and the temperature of the bread baking mold can be accurately measured and good bread can be baked. be.

Furthermore, a firing chamber 30 is fixed to the chassis 21 via a pulley bearing stand 40, which is equipped with a lower heater 27 at the inner bottom and a heat insulating material 28 around the outer periphery. Inside this baking chamber 30, there is a bread baking mold 31 with a removable kneading blade 32 on the inner bottom, and a blade shaft 34 and an upper connector 37 are connected to a bread mold stand 35 fixed to the bottom of the bread baking mold 31. supported. Furthermore, the bread baking mold 31 is removably fitted into a pulley bearing stand 40 fixed to the chassis 21. A pulley shaft 39 to which the large pulley 26 and lower connector 38 are attached is held by the pulley bearing stand 40. Further, an elastically supported temperature detection section 49 protrudes from the side surface of the firing chamber 30 on the side opposite to the motor 22.
The bread baking mold 31 is disposed between the bread baking mold 31 and the temperature sensing portion 49, and the temperature sensing portion 49 is in pressure contact with the side surface of the baking mold 31.

Further, an annular upper heater 41 is disposed around the entire circumference inside the upper part of the firing chamber 30. Also, firing chamber 3
0 has a lid 42 that can be opened and closed and a lid 4 that can be opened and closed.
There is a mounting shaft 44 protruding from the center of the lower surface of the heater 41 and an inner lid 43 elastically supported by a presser spring 45. It is designed to be pressed against the top surface. Further, the lid body 42 is provided with an opening knob 47 and a latch 48 for opening the lid body 42. In addition, the small pulley 24 of the shaft of the motor 22
A reciprocating pump 54 is provided with a pin shaft 56 at a position slightly eccentric to the motor axis on the side, and further has an elastic membrane suction plate made of rubber or the like vibrated on the side of the chassis 21.
A pump-side pin shaft 57 is fixed to the top of the elastic membrane suction plate, and is connected to the pin shaft 56 by a connecting rod 55. Furthermore, the reciprocating pump 54
The discharge pipe 53 communicates with a water tank 52 attached to the main body 20, and the water supply pipe 51 communicates with a water supply port 50 opened so that water is sprayed onto the bread baking mold 31 in the baking chamber 30. There is. Note that the reciprocating pump 54, the discharge pipe 53, and the water supply pipe 51 constitute a water supply device. Further, 61 is a switch panel for inputting settings such as baking time. Further, 62 is a control device for determining and outputting control conditions for the motor 22, lower heater 27, upper heater 41, etc. based on the input information from the switch panel 61 and the temperature detection section 49.

Next, the operation of the embodiment of the present invention will be explained.
A bread baking mold 31 and kneading blades 32 are set in the baking chamber 30, and ingredients such as flour are introduced. Lid body 42
, fill the water tank 52 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 input from the switch panel 61, and when the predetermined time comes, the motor 22 starts operating and kneading is performed. At this time, at the same time, a pin shaft 56 provided on the small pulley 24 on the motor shaft side, eccentrically from the motor axis, rotates. The connecting rod 5 is pivotally supported on this pin shaft 56.
5, the pump-side pin shaft 57 reciprocates and vibrates the elastic membrane suction plate of the reciprocating pump 54, thereby drawing air from the discharge pipe 53 of the pump to the water tank 52.
to be pumped to.

Then, due to the pressure of the air pumped into the water tank 52, water is poured into the baking mold 31 from the water supply port 50 through the water supply pipe 51, and is kneaded with ingredients such as wheat flour by the kneading blades 32. Based on the information on the operating time of the temperature detection unit 49 and the motor 22, the steps of kneading operation stop, primary fermentation, degassing, shaping fermentation, and baking are automatically performed, and the bread is baked at the set time. It is something.

Bread is baked automatically as described above, but by placing the bread baking mold 31 between the temperature detection part 49 and the motor 22 and bringing the temperature detection part 49 into contact with the bread baking mold 31, the bread is baked automatically. Since there is no need to worry about heat generated by the motor cooling fan 23 or direct exposure to hot air from the motor cooling fan 23, the accurate temperature of the bread baking mold 31 can be measured, and this information is sent to the control device 62 to perform optimal control for bread making. , it is possible to bake good bread regardless of the outside temperature.

Effects of the Invention As is clear from the description of the above embodiments, the automatic bread maker of the present invention has a simple configuration that takes into account the arrangement of the temperature detection section, motor, and bread baking mold, and is particularly capable of measuring the temperature of bread dough during the kneading process. Since it is not affected by the heat generated by the motor or the hot air from the motor cooling fan, the kneading process can be carried out accurately, and as a result, the kneading process is carried out at an appropriate temperature, so that good bread can be baked.
