DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bread maker for automating the steps required for bread making and for making bread easily simply by setting ingredients. It is related to the one with a menu that can be manufactured.

[0002]

2. Description of the Related Art A conventional bread maker is equipped with a bread container provided with kneading blades in a baking chamber provided with a motor, a heater and a temperature sensor. Are kneaded, fermented while maintaining the bread material at a predetermined temperature by a heater and a temperature sensor, and finally baked as bread to produce bread. And recently, in addition to making ordinary bread, bread making machines have also added menus such as French bread and soft bread, and handmade menus that make only bread or bread dough with raisins, etc., as a multifunctional product. Is recognized.

[0003]

Under these circumstances, the applicant has a theme of whether ice cream can be made in a bread maker. It focuses on the fact that the steps required for ice cream production are performed by stirring and mixing which requires temperature control. That is, in the case of cooking using eggs such as ice cream, the function of a bread maker is preferable in that it is preferable to heat-treat at 70 ° C. for 1 minute or more in order to prevent the propagation of various bacteria and that the ingredients are frozen while stirring. Is considered that all can be substituted. On the other hand, conventional bread machines have functions of kneading, heating and temperature control, but do not have a function of cooling the material. An object of the present invention is to provide a bread maker which has solved such problems.

[0004]

In order to solve such problems, the present invention provides a conventional bread maker having a kneading and heating function by adding a cold storage container to be replaced with a bread container. A cooling function is added to a conventional bread maker to enable the production of ice cream. The ice cream menu is performed by sequentially executing an ice heating menu and an ice cooling menu stored in the storage unit. Of these, the ice heating menu is affected by the ambient temperature and the cold storage container, so it is difficult to set a clear time, so the maximum time Tmax elapses or the minimum time Tmin
Within the time from the lapse of the maximum time Tmax to the appropriate temperature αm
The heater and the motor are operated until the temperature reaches in, or the upper limit temperature αmax is reached before the minimum time Tmin elapses, or any of the conditions is satisfied.

[0005] As a safety means for preventing the bread making operation when the regenerator is set, a container discriminating means for discriminating whether the container mounted in the baking chamber is a pan container or a cooling container is provided. A means is provided for not starting when it is determined that the container being set is not appropriate for the menu to be executed.

[0006] The cold storage container is constituted by a double-structured container filled with a cold storage agent except for the upper surface. A lid is provided on the upper surface to prevent escape of cool air. An opening for charging an ice cream material is provided in the container, and a funnel-shaped material charging member is detachably attached to the opening.

[0007]

According to the present invention, since the cold storage container is provided separately from the bread container, both the containers can be replaced according to the menu and used together, so that the cooling and cooking can be performed in the bread maker. Therefore, in normal baking,
It goes without saying that it is only necessary to set the bread ingredients in the bread container and execute the desired bread making menu.However, when making ice cream, put the ice cream ingredients in the bread container and execute the ice heating menu. For example, the heat sterilization process is performed under optimal conditions, and then the ice-cooling menu is executed, and the ice-cream material is charged into the cold storage container with stirring, thereby cooling and coagulating the ice cream.

And a start key 44 for starting and restarting cooking
And a stop key 45 for canceling the operation and canceling the setting.
And a reservation timer key 46 for setting a reservation cooking time. On the display panel 42, the cooking time, the number of the cooking menu selected by the menu key 43, and the like are displayed.

The cooking machine can execute various menus such as a bread menu from kneading to baking, an ice heating menu for heat sterilizing ice cream ingredients, an ice cooling menu for cooling ingredients, and a frozen yogurt menu. The motor and heater drive data required for each menu are written in the memory 31 of the microcomputer 32.

Next, the operation of cooking according to the present invention configured as described above will be described for each menu. In the case of performing bread-making cooking In order to execute various bread-making menus, the necessary materials are set in the bread container 16 and installed in the baking chamber 3 by the above-described method. (Set a reservation timer if necessary) and input the start key 44. After confirming that the bread container 16 is set by the container determination switch 53,
The motor 4 is driven to rotate the kneading blades 19 to knead the material. Next, the temperature in the firing chamber 3 is measured by the heater 13 and the temperature sensor 1.
4, the dough is fermented while maintaining the fermentation temperature, and finally the dough is baked to make bread.

When making ice cream When manufacturing ice cream, execute an ice heating menu in which the ingredients are heated and sterilized in a bread container, and then cool the ingredients to an appropriate temperature in a refrigerator or the like. The ice cooling menu, which is gradually added to the cool storage container and hardened, is executed, and the dish is completed. The operation of each of these menus is as follows.

A. Ice heating menu Put the ice cream material in the bread container 16 and bake room 3
Set inside. When the user selects the ice heating menu with the menu key 43 and inputs the start key 44, the program is executed according to the flowchart shown in FIG. When it starts (1), it is confirmed whether the container set by the container determination switch 53 is the bread container 16 (2). If the container is not a bread container, the subsequent operation is stopped, an alarm is given by the buzzer 38, and the fact is displayed on the display panel 42 (3).

If the container is correct, a timer is set (4), the motor 4 is driven and the heater 13 is energized (5), the timer in the microcomputer 32 starts counting, and the minimum time Tmin required for heat sterilization is set. (6) The ice cream material is heat-sterilized at the proper temperature. Here, if the temperature detected by the temperature sensor 14 reaches the upper limit temperature αmax before the timer elapses the minimum time Tmin, the operation is immediately terminated at that time because there is a risk of deterioration of the material. (7).

If the timer elapses the minimum time Tmin in the process (6), it is checked whether the temperature detected by the temperature sensor 14 reaches the required temperature αmin before the timer elapses the maximum time Tmax (8). As soon as the temperature αmin is reached (9), the motor 4 and the heater 13 are stopped (1).
0) Terminate the operation. Here, if the temperature detected by the temperature sensor 14 does not reach the required temperature αmin before the timer reaches the upper limit time Tmax, the upper limit time Tm
The operation ends when ax has elapsed.

During this time, the motor 4 is constantly rotating at a constant speed. In this way, the end of the operation is not controlled by the unique temperature and time, but the operation is ended at a point where the conditions are suitable within a certain range,
Heat sterilization can be performed according to the ambient atmosphere temperature and the amount of the material. Further, the upper limit and lower limit of each timer time and the set temperature were determined by experiments so that the material could be heated to about 70 ° C. regardless of the atmosphere.

B. Ice cooling menu The cold storage container 21 previously frozen in the freezing room is installed in the baking room 3, the ice cooling menu is selected by the menu key 43, and the start key 44 is input, whereby the program is executed according to the flowchart shown in FIG. Is executed. When started (11), it is confirmed whether the container set by the container discriminating switch 53 is the cold storage container 16 (12). If it is not a cold storage container, the subsequent operation is stopped, a buzzer 38 issues an alarm and the display panel 42
(13).

If the container is correct, a timer is set (14), the motor 4 is driven (15), and the microcomputer 32
The timer inside starts counting. When an ice cream material is put into the cold storage container 21 in this state through the material charging port 51 with the funnel 52 attached thereto, the inner surface of the cold storage container 21 is rubbed and cooled by the stirring blades 24 to freeze and solidify as ice cream. . The reason why the material is transferred into the cold storage container after the start of the stirring is that the charged material freezes as soon as it comes into contact with the cold storage container. When the timer elapses the time Ta (16), the buzzer 38 sounds as a measure of completion (17). At this stage, since the ice cream is still soft, the motor 4 is not stopped, and the rotation speed is increased (18). . When an additive such as raisins is added to the ice cream, it is good to put in at this timing, and the buzzer here also has a meaning of notifying the timing of adding the additive. Thereafter, the operation is stopped by the stop key 45 according to the user's request.
9) Forcibly remove the motor 4 in consideration of the risk of motor lock.
Is stopped (20).

The motor 4 rotates at a slightly middle speed immediately after the start, and rotates at a low speed until the time Ta elapses.
It rotates at a medium speed until the upper limit time Tb elapses after elapse. This is done by thawing the frozen shaft when freezing the cold storage container in a freezer etc. at a slight medium speed immediately after the start, then cooling the whole material well by low speed rotation and solidifying it, and then at medium speed rotation The additives are mixed well. Thus, a smooth ice cream is completed. The respective timer times were determined by experiments so that the material could be hardened regardless of the atmosphere.

Since the ice heating menu and the ice cooling menu are independent menus, cooking other than ice cream is also possible. For example, in the ice cooling menu, sherbet and the like can be cooked. In addition, frozen yogurt has a special menu separately because it is highly viscous and tends to harden, but the operation is the same as that of the ice cooling menu except that the setting time of the timer is short.

[0030]

The present invention is configured as described above, so that a cold storage container can be set in a conventional bread maker, so that ice cream that cools while stirring can be manufactured. Product value is improved. In addition, it is possible to cook sterilizing and heating the ingredients necessary for the production of ice cream, and it is possible to execute all the steps required for ice cream with one unit. These menus are stored as independent menus and have a function of determining the container to be set, so that there is no failure such as scorching or hardening the material.
