Description

Description: TECHNICAL FIELD The present invention relates to a bread maker having a plurality of containers for storing bread ingredients.

2. Description of the Related Art In recent years, a bread maker that automatically bakes bread when a bread material is put in a container and operation is started has become widespread.
Moreover, a bread maker capable of increasing the number of containers and baking many breads at once has been demanded.

A conventional bread maker of this type has a configuration shown in FIG. That is, the storage 2 is provided in the main body 1, and two containers 3 a and 3 b are disposed in the storage 2. This container 3a,
Blades 5a, 5b for kneading the bread ingredients to be fed are rotatably arranged at the inner bottom portion of 3b, and the rotational force of the motor 8 is transmitted to the blades 5a, 5b via the pulleys 6a, 6b and the belt 7. It is a configuration that is done. The above blades 5a, 5b, pulleys 6a, 6b, belt 7 and motor 8 constitute a kneading means. Further, heating means 4a, 4b are arranged below the containers 3a, 3b, and a temperature sensor 9 for detecting the temperature of the container 3a is in contact with the side wall of the container 3a. The temperature sensor 9 is a temperature detecting means 10
The temperature detection means 10 outputs a temperature signal of the container 3a to the control means 11. Control means 11
Controls the motor 8 and the heaters 6a and 6b by operating the motor driving means 12 and the heater driving means 13 based on the temperature signal.

Next, control of the control means 11 will be described. First, when the operation is started, the motor driving means 12 is operated and the container is
The bread ingredients in 3a and 3b are kneaded by the blades 5a and 5b (kneading step). When this kneading step is completed, the heater driving means is operated to control the temperature of the vessels 3a and 3b to the fermentation temperature (fermentation step). At this time, the control means 11
The energization control of the heaters 4a and 4b is performed based on the temperature signal of. Then, when the fermentation process is completed, the process moves to a baking process in which the temperature of the containers 3a and 3b is raised to the baking temperature. In this baking step, the control means 11 inputs a temperature signal from the temperature detection means 10, operates the heater driving means 13 so that the temperature of the container 3a reaches the baking temperature, and controls the heating amounts of the heaters 4a and 4b. There is. The temperature signal of the temperature detection means 10 at this time is temperature information only on the container 3a side, but the control means 11
Is to control the heating of the heaters 4a and 4b by regarding that the temperature on the container 3b side is substantially equal to the temperature on the container 3a side.

Problems to be Solved by the Invention However, in the conventional configuration, since the heaters 4a and 4b are controlled only by the temperature signal on the container 3a side, for example, the container 3a
When the rated amount of bread material is put into the container side and the small amount of bread material is put into the container 3b side, there is a problem that a small amount of bread on the container 3b side becomes too burned. This is because the container with less bread ingredients has a faster temperature rise, and when the temperature of the rated amount of the container reaches the baking temperature, the temperature of the small amount of container becomes higher than that. If a small amount of bread material is put into the container 3a side with which the temperature sensor 9 is in contact, the container 3b containing the rated amount of bread material is introduced.
Since the heating amounts of the heaters 4a and 4b are suppressed until the side reaches the baking temperature, there is a problem that the bread is baked on the container 3b side.

In view of the above problems, it is an object of the present invention to prevent the bread from being excessively burnt or baked 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 container provided corresponding to each container. Heating means, temperature detecting means for detecting the temperature of each container, average temperature detecting means for calculating a temperature average by inputting signals from the temperature detecting means, and baking means by controlling the heating means and kneading means A control means for advancing the process is provided, and the control means is configured to control the heating means by a signal of the average temperature detecting means in the firing step.

According to the above configuration, the temperature detection means detects each temperature of a plurality of containers having different amounts of bread ingredients, and the heating means is controlled based on the average value of the detected temperatures. Raw baking can be prevented.

Embodiment An embodiment of the present invention will be described below with reference to FIG. 1 and FIG.

FIG. 1 shows the configuration of the bread maker in the present embodiment.
The same parts as those of the conventional configuration are designated by the same reference numerals, and the description thereof will be omitted.

In FIG. 1, 10a and 10b are temperature detecting means to which the temperature sensors 9a and 9b contacting the containers 3a and 3b are connected, and the temperature signals of the temperature detecting means 10a and 10b are output to the average temperature detecting means 14. Has been done. This average temperature detecting means 14 is a temperature detecting means.
The average value of the temperature signals from 10a and 10b is calculated, and the control means 11
Output to. Then, the control means 11 uses the average temperature detection means 14
The heating amounts of the heaters 4a and 4b in the firing process are controlled based on the average temperature signal from the. The control means 11 and average temperature detection means 14 are composed of a microcomputer 17.

Next, the control flow of the microcomputer 17 will be described with reference to FIG. First, when the operation is started, step 2
Execute the kneading process and fermentation process at 1,22. When the fermentation process is completed, the heaters 4a, 4b are energized, and the process proceeds to a firing process for heating the containers 3a, 3b. In this firing process, first,
In step 23, the temperature of the containers 3a, 3b is input by the temperature detecting means 10a, 10b, and in step 24, the average temperature detecting means 14 calculates the average temperature. Then, the heaters 4a and 4b are turned on until the average temperature reaches the set value (step 26), and when the set value is reached, the heater is turned off (step 27), and the above operation is repeated until a predetermined time has passed (step 28). , Finish driving.

Change the temperature of each container 3a, 3b during the firing process
It will be described with reference to the drawings. The curve A in the figure shows the temperature change of the container into which a small amount of bread material has been charged, and the curve B shows the temperature change of the container into which the rated amount of bread material has been charged. The curve C shows the average value of the curves A and B. When shifting to the firing step, the heaters 4a and 4b start to be energized, and the temperature of the container starts to rise. When the curve C reaches the set temperature Ta,
The control means 11 controls the heaters 4a and 4b so that the temperature of the curve C can be maintained at the set value Ta. That is, the heaters 4a, 4b are energized until the set value Ta suitable for the average baking temperature is reached, and when the temperature Ta is reached, the heaters 4a, 4b are energized,
Turn off and keep the baking temperature Ta. On the other hand, the temperature of the container with a large capacity rises as shown by curve B, and the heater 4
Since the heating amounts of a and 4b decrease, the rate of temperature rise further decreases, and finally reaches the baking temperature Ta. Further, since the heating amount of the container having a small capacity is controlled so that the heaters 4a and 4b have the set value Ta, the temperature starts to drop at time ta as shown by the curve A and finally reaches the baking temperature Ta. .

In addition, in the present embodiment, the case where there are two containers is shown, but it goes without saying that the effect of the present invention can be achieved even in the case where three or more containers are provided.

EFFECTS OF THE INVENTION As is clear from the above examples, according to the present invention,
Since the heating means in the baking process is controlled based on the average temperature of the plurality of temperature detecting means, even when the bread ingredients are put into the plurality of containers differently, the bread is too burnt or is baked in a raw baking state. Can be prevented.
