Abstract

PURPOSE: To prevent bread from being baked in a too much scorched state even when a bread material is charged in a plurality of containers in different amts. by controlling a heating means in a baking process on the basis of a temp. signal reaching a set value most early. CONSTITUTION: The temp. signals of temp. detection means 10a, 10b to which temp. sensors 9a, 9b coming into contact with containers 3a, 3b are connected are outputted to a changeover means 14 and a comparing means 15. The comparing means 15 compares the set temp. value from a set value memory means with the temp. signals from the temp. detection means 10a, 10b to judge the temp. detection means 10a or 10b rapidly reaching the set temp. value. By this constitution, the respective temps. of a plurality of containers different in the amt. of the bread material are detected by the temp. detection means 10a, 10b and, since a heating means is controlled on the basis of the temp. signal reaching the set value most early among the detected temps., bread can be prevented from being too much scorched.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a bread making machine equipped with a plurality of containers for storing bread ingredients.Prior art In recent years, when bread ingredients are placed in a container and operation is started, Bread making machines that automatically bake bread are becoming popular. Moreover, there is a growing demand for a bread maker that can increase the number of containers and bake more bread at one time.

A conventional bread making machine of this type had a configuration shown in FIG.

That is, a storage 2 is provided within the main body 1, and two containers aa and ab are arranged within this storage 2. This container 3
At the inner bottom of N, 3b, blades 5Δ, sb for kneading the input bread ingredients are rotatably arranged, and Boo! J
- The rotational force of the motor 8 is applied to the blade 6N via 6a, 6b and the belt 7.

6b. The above blade 5a.

sb, pulleys 6a, 6b, belt 7, and motor 8
This constitutes the kneading means. Further, heating means 4a, 4b are arranged below the containers 3&, 3b, and a temperature sensor 9 for detecting the temperature of the container 3& is in contact with the side wall of the container 3a. The temperature sensor 9 is connected to a temperature detection means 10, and the temperature detection means 10 outputs a temperature signal of the container 3a to the control means 11Vr. The control means 11 controls the motor drive means 12 and the heater based on the temperature signal.
The motor drive means 13 is operated, and the motor 8, heater ea, s
b.

Next, the control of the control means 11 will be explained.

First, when the operation is started, the motor drive means 12 is operated to move the bread ingredients in the containers 31L, 3b to the blades 51L,
5b (kneading step). When this kneading step is completed, the heater drive means is operated to
Control the temperature of b to the fermentation temperature (fermentation process). At this time, the control means 11 controls the heater 41L based on the temperature signal from the temperature detection means 10.

4b conducts energization control. When the fermentation process is completed, a baking process is started in which the temperature of the containers 3a and 3b is raised to the baking temperature. In this firing process, the control means 11 inputs a temperature signal from the temperature detection means 1o, and
The heater drive means 13 is operated so that the temperature of a reaches the baking temperature, and the heating amount of the heaters 41L and 4b is controlled. At this time, the temperature signal of the temperature detection means 1o is temperature information only on the side of the container 3a, but the control means 11
The heating of the heaters 4a and 4b is controlled by assuming that the temperature on the b side is almost equal to the temperature on the container 3a side.

Problems to be Solved by the Invention However, in the conventional configuration, heaters 4tL, 4bf containers 3&
For example, if you put the rated amount of bread ingredients into container aa and a small amount of bread ingredients into container ab, the small amount of bread in container 3b will burn. The problem was that it was too much. The reason for this is that the temperature of the container with less bread material rises faster, so that when the temperature of the container with the rated amount reaches the baking temperature, the temperature of the container with the smaller amount will rise above that temperature.

In view of the above problems, it is an object of the present invention to prevent bread from becoming too burnt even when different amounts of bread ingredients are put into a plurality of containers.

Means for Solving the Problems In order to achieve the above object, the present invention provides a plurality of containers for storing bread ingredients, a kneading means for kneading the bread ingredients in each container, and a kneading means provided corresponding to each container. a heating means; a temperature detection means for detecting the temperature of each container; and a heating means into which a signal from the temperature detection means is input.

A control means for controlling the kneading means to advance the bread manufacturing process, and the control means controls the heating means according to a signal of any one of the temperature detection means that reaches a set value earliest in the baking process. This is the configuration.

According to the configuration described above, the temperature detection means detects the respective temperatures of a plurality of containers containing different amounts of bread ingredients, and the temperature signal that reaches the set value earliest among the detected temperatures, that is,
Since the heating means is controlled based on the temperature signal of the container containing the least bread material, it is possible to prevent the bread from becoming too burnt.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2.

The structure of the bread making machine in this embodiment is shown in FIG. 1, and the same parts as those in the conventional structure are given the same reference numerals, and the explanation thereof will be omitted.

In FIG. 1, 10&, 10b are containers 3&.

Temperature sensors 9a and 9b in contact with the temperature sensor 3b are connected to the temperature detection means, and temperature signals from the temperature detection means 10a and 10b are outputted to the switching means 14 and the comparison means 16. The comparison means 16 compares the set temperature value from the set value storage means and the temperature signals from the temperature detection means 10m and 10b, and determines which temperature detection means 1o&or 10b reaches the set temperature value sooner. Based on this determination result, the switching means 14 switches the temperature signal from the temperature sensing means 10a or 10b and outputs it to the control means 11. and,
The control means 11 controls the heating amount of the heaters 4a and 4b in the firing process based on the temperature signal from the switching means 14. The control means 11, the switching means 14, the comparison means 15
and the setting value storage means 16 is a microcomputer 17.
It consists of

Next, the control flow of the microcomputer 17 will be explained with reference to FIG. First, when you start driving, step 2
1. Execute the kneading step 1 fermentation step in step 22. When the fermentation process is completed, electricity is started to be applied to the heaters 4a and 4t), and the container 3
The process moves to a firing step in which parts a and 3b are heated. In this firing process, first, in step 23, it is determined whether the temperature of the container 3a has reached a set value, and if it has reached, step 26
input the temperature signal to the temperature detection means 10a, and
If the set value has not been reached in step 23, it is determined in step 24 whether the container 3b has reached the set value, and if it has reached the set value, a temperature signal is input to the temperature detection means 1ob in step 25, and the set value is reached. If it has not been reached, the process returns to step 23 and the above contents are repeated. And temperature detection means 10
If it is determined to switch the heaters 4a and 10b, that is, if a temperature signal that has reached the set value quickly is input, the control means 11 controls the energization of the heaters 4a and 4b based on the input temperature signal in step 27. . And step 28
When a predetermined period of time has elapsed, the operation is terminated.

The temperature change of each container 31L, 3b in the above firing process will be explained with reference to FIG. Curve M in the figure shows the temperature change of the container into which a small amount of bread ingredients has been put, and curve B shows the temperature change of the container into which the rated amount of bread ingredients has been put. When the firing process begins, the heaters 4sL and 4sab start to be energized, so the temperature of the container begins to rise. And the set temperature rrLT
When one of the containers (in this case, a small container) reaches temperature b, the control means 11 controls the heaters 4a and 4b so that the temperature reaches the curve m. That is, the baking temperature TI
The heaters 4a, 4b are energized until the temperature reaches L(T,)Tb)K, and at the time t1 when the temperature vTIL is reached, the heaters 4a, a
The bread baking temperature T is maintained by turning on and off the power supply b. On the other hand, the temperature of the container with a large capacity rises as shown by curve B, and at time t&, the temperature of the container reaches 41L.

Since the heating amount of 4b decreases, the rate of temperature increase further decreases and finally reaches the baking temperature T&.

In this case, heaters at and 4b are turned on at time t&.

Although it is set to off control, the heater 4m on the side of the container with rated capacity is
Alternatively, if energization of heater 4 & or 4b on the small container side is stopped by controlling 4b, the amount of heat transferred to the rated capacity container side increases, thereby preventing a decrease in the temperature rise rate of the rated capacity container. It is possible to bake the bread in two containers in a better condition.

In this embodiment, a temperature signal is inputted to the comparison means 16 to determine which container has a faster rise in temperature. It may be determined that the temperature rises quickly.In short, it is sufficient if the temperature rises quickly can be detected.

Also, the case where there are two containers is shown, but there are three or more containers)
It goes without saying that the effects of the present invention can also be achieved in a device equipped with a container.

Effects of the Invention As is clear from the above embodiments, according to the present invention, in order to control the heating means in the baking process based on the temperature signal that reaches the set value earliest, bread ingredients are charged differently into a plurality of containers. Even in such a case, it is possible to prevent the bread from being baked in an excessively burnt state.
