Description

  The present invention relates to an automatic bread maker used for general household use.

  Conventionally, there are known various types of automatic bread machines of this type (for example, see Patent Document 1: Japanese Patent Laid-Open No. 9-75230).

  FIG. 5 is a longitudinal sectional view of a conventional automatic bread maker. As shown in FIG. 5, the conventional automatic bread maker includes a kneading container (also referred to as a bread-making container) 101 for storing cooking ingredients. A cylindrical kneading container base (also referred to as a pedestal) 102 is provided at the bottom of the kneading container 101. The kneading container table 102 is configured to be bayonet-coupled to a container support table (also referred to as a baking container mounting table) 103.

  A cylindrical rib 104 is provided at the bottom of the kneading container 101 so as to surround the periphery of the kneading container base 102. By fitting the outer peripheral side surface of the rib 104 to the inner peripheral side surface of the upper end opening of the container support base 103, the kneading container base 102 is positioned at an appropriate position of the container support base 103 without rattling.

  FIG. 6 is a perspective view showing a structure in which the kneading container base 102 and the container support base 103 are connected with a bayonet. As shown in FIG. 6, two quadrangular protrusions 102a are provided on the outer peripheral side surface of the kneading container base 102 at intervals of 180 degrees. On the other hand, two notches 103a that are connected to the two protrusions 102a and bayonet are provided on the inner peripheral side surface of the container support base 103. The upper end of the protrusion 102a and the upper end of the notch 103a are formed obliquely. In addition, two kneading container placement ribs 103b are provided on the inner bottom of the container support base 103 at intervals of 180 degrees. Each kneading container mounting rib 103b is provided at a position about 90 degrees away from each notch 103a with the center of the inner bottom portion of the container support base 103 as the center. By kneading bread dough with kneading blades (not shown) provided in the kneading container 101 in a state where the kneading container base 102 is placed on each kneading container placing rib 103b, an operation sound generated during the kneading is generated. Can be small.

JP-A-9-75230

  However, in the conventional automatic bread maker, when the dough is kneaded, the bayonet connection between the kneading container table 102 and the container support table 103 is loosened, and the kneading container 101 may be loose. That is, the dough kneading operation is performed by intermittently rotating the kneading blade and rolling the dough in the kneading container 101. At this time, when the kneading blade rotates and presses the dough, the reaction force received by the kneading blade from the dough acts in the direction of strengthening the bayonet coupling. For this reason, the kneading container 101 is firmly fixed without rattling. On the other hand, when the kneading blade stops rotating and the bread dough rolls in the kneading container 101 due to the inertial force, the reaction force that the kneading blade receives from the bread dough may act in the direction of weakening the bayonet coupling. Thereby, when the said bayonet coupling | bonding loosens or remove | deviates, rattling arises in the kneading container 101. FIG.

  In the conventional automatic bread maker, the kneading container table 102 is mounted on each kneading container mounting rib 103b. Therefore, when the kneading container 101 is rattled during the kneading operation, the lower end of the kneading container table 102 is supported by the container. It may happen that the lower end of the kneading container table 102 is scraped by coming into contact with the inner bottom of the table 103 and rubbing. Then, the shaving powder generated at this time adheres to the lower end of the kneading container table 102, and when the kneading container 101 is placed on a table or the like after the bread making process, the table may be blackened.

  Next, the structure in which the kneading container base 9 and the container support base 4 are bayonet-coupled will be described in more detail with reference to FIGS. FIG. 2 is a perspective view of the kneading container base 9 and the container support base 4. 3 is a cross-sectional view showing a state in which the kneading container base 9 and the container support base 4 are bayonet-coupled, and FIG. 4 is a partially enlarged cross-sectional view of FIG.

  As shown in FIG. 2, two bayonet protrusions 91 are provided on the outer peripheral side surface of the kneading container base 9 at intervals of 180 degrees in plan view. On the other hand, two bayonet grooves 41 that are connected to the bayonet protrusion 91 and the bayonet are provided on the inner peripheral side surface of the container support 4.

On the other hand, the lower end 93 of the kneading container base 9 and the inner bottom portion 43 of the container support base 4 are not in contact with each other, and a gap 51 is formed between them. At this time, the tip (outer peripheral side) 92b of the annular rib 92 of the kneading container base 9 is on the inner peripheral side (excluding the part corresponding to the bayonet groove 41) of the container support base 4 in the vicinity of the stepped part 42. Contacting (fitting). Furthermore, the outer peripheral side surface 9a of the kneading container base 9 positioned below the annular rib 92 of the kneading container base 9 is in contact with (fitted to) the inner peripheral side surface of the container support base 4 (except for the portion corresponding to the bayonet groove 41). )doing.

  Next, the operation and effect of the automatic bread maker according to the present embodiment having the above-described configuration will be described.

  As shown in FIG. 3, the kneading container base 9 is attached to the container support base 4 by the annular rib 92 being placed on the step portion 42 and the bayonet protrusion 91 being bayonet-coupled to the bayonet groove 41. In this state, a bread making process including a kneading operation of bread dough is performed.

  The kneading operation of the dough is performed by intermittently rotating the kneading blade 10 and rolling the dough in the kneading container 7. At this time, when the kneading blade 10 rotates and presses the dough, the reaction force received by the kneading blade 10 from the dough acts in the direction of strengthening the bayonet coupling. For this reason, the kneading container 7 is firmly fixed without rattling.

  On the other hand, when the kneading blade 10 stops rotating and the bread dough rolls in the kneading container 7 due to inertial force, the reaction force received by the kneading blade 10 from the bread dough may act in the direction of weakening the bayonet coupling. In this case, the kneading container base 9 rotates in the direction of loosening the bayonet coupling with respect to the container support base 4. As a result, the tip end portion 92b of the annular rib 92 and the outer peripheral side surface 9a of the kneading container base 9 positioned below the annular rib 92 are rubbed against the inner peripheral side surface of the container support base 4, respectively. Can occur.

  In the present embodiment, the annular rib 92 is placed on the step portion 42, and the gap 51 is formed between the lower end 93 of the kneading container base 9 and the inner bottom part 43 of the container support base 4. The shaving powder can be prevented from adhering to the lower end 93 of the base 9. Therefore, when the kneading container 7 is placed on the table, the table can be prevented from becoming dirty.

  Further, in the present embodiment, the kneading container base 9 is the container so that the tip 92b of the annular rib 92 and the outer peripheral side surface 9a of the kneading container base 9 are in contact with the inner peripheral side surface of the container support base 4, respectively. It is attached to the support base 4. Thereby, since the movement of the kneading container base 9 in the horizontal direction is restricted, rattling of the kneading container 7 can be suppressed. Moreover, generation | occurrence | production of the loud rattling by the rattling of the kneading container 7 can also be suppressed.

  In the above description, the tip end 92b of the annular rib 92 and the outer peripheral side surface 9a of the kneading container base 9 are in contact with the inner peripheral side surface of the container support base 4, respectively, but the present invention is not limited to this. . For example, a gap 52, between the tip 92b of the annular rib 92 and the inner peripheral side surface of the container support base 4, and between the outer peripheral side surface 9a of the kneading container base 9 and the inner peripheral side surface of the container support base 4, respectively. 53 may be provided. By providing the gaps 52 and 53, the kneading container base 9 can be easily inserted into the container support base 4, and the handleability can be improved.

  The gap 52 is preferably narrower than the gap 53. Thereby, when rattling occurs in the kneading container 7, before the outer peripheral side surface 9 a of the kneading container base 9 contacts the inner peripheral side surface of the container support base 4, the tip end portion 92 b of the annular rib 92 and the container support base 4 Will contact the inner peripheral side. As a result, the amount of shavings generated by rubbing the outer peripheral side surface 9a of the kneading container base 9 and the inner peripheral side face of the container support base 4 can be suppressed or eliminated. Can be further suppressed.

  Further, when the gaps 52 and 53 are provided, the bayonet protrusions 91 and the bayonet grooves 41 are provided at two positions on the outer peripheral side surface of the kneading container base 9 at a 180 degree interval in a plan view as in this embodiment. Is preferred. That is, it is preferable that the kneading container base 9 and the container support base 4 are configured to be bayonet-coupled at two locations. Here, when the kneading container base 9 and the container support base 4 are configured so as to be bayonet-coupled at one place, the rotational axis of the kneading container base 9 is likely to be displaced from the original rotational axis. In this case, rattling of the kneading container 7 is generated, and the amount of shavings generated by rubbing the tip 92b of the annular rib 92 and the inner peripheral side surface of the container support 4 increases. Further, even when the kneading container table 9 and the container support table 4 are configured to be bayonet-coupled at three or more locations, the kneading of the kneading container 7 cannot be suppressed. This is because it is difficult to eliminate the dimensional variations of the respective parts, and thus the bayonet coupling cannot be performed equally reliably. On the other hand, when it comprises so that the kneading container base 9 and the container support stand 4 may be bayonet-coupled in two places like this embodiment, the shift | offset | difference of the rotating shaft of the kneading container base 9 can be suppressed. . Moreover, even if there is some variation in the dimensions of the parts, the bayonet coupling can be performed more reliably.

  The automatic bread maker according to the present invention can suppress contamination of the table when the kneading container after completion of the bread making process is placed on a table or the like. It is useful as an automatic bread maker.
