  In the bread maker described in Patent Document 1, since the solenoid is disposed on the inner side surface of the bottom wall portion in the outer portion, the solenoid plunger rod is a long one extending from the bottom of the main body space to near the top. As a result, the tooling operation, which is the opening operation of the lid of the container, lacks stability, and the manufacturing cost increases.

  Also in the bread maker described in Patent Document 2, the solenoid is disposed in a lateral orientation between a base member provided on the inner surface of the bottom wall portion of the outer shell portion of the main body and the outer surface of the bottom wall portion of the casing. Therefore, as a link member pivotally attached to the upper and lower intermediate portion on the outer side surface of the side wall portion of the casing, it extends from the upper and lower intermediate position between the bottom wall portion of the outer shell portion and the bottom wall portion of the casing to near the upper portion of the main body space. It is necessary to use a long one, and as a result, as in the former case, the container operation, which is the opening operation of the container container lid, lacks stability, and the manufacturing cost increases.

  Moreover, since other parts such as a motor and a power cord are disposed in the bottom space between the bottom wall portion of the outer shell portion and the bottom wall portion of the casing, the lid of the container is opened. There is a problem that the product size is increased due to the arrangement of the solenoid as the driving source of the operation at the bottom of the main body.

  The present invention has been made in view of the above circumstances, and its main problem is that the container is an opening operation of the lid of the container by rationally improving the existing space effectively. An object of the present invention is to provide a bread maker capable of improving operational stability, reducing product dimensions, and reducing manufacturing costs.

In order to achieve the above object, a bread maker according to the present invention includes a main body including a casing that houses a bread case through an opening, a lid that closes the opening of the casing, and the lid And a lid opening means for opening and closing the lid of the container, and the lid opening means includes a lock mechanism for locking the lid in a closed posture. A swingable link member for unlocking the lock mechanism, and a lid opening drive mechanism having an operation force application unit for applying an unlock operation force to the first motion transmission unit of the link member. And a bread maker in which a handle receiving portion for receiving a handle provided in the main body is formed in the main body.
In the main body space formed between the outer side surface of the side wall portion of the casing and the inner side surface of the side wall portion in the outer portion of the main body that covers the outer side of the side wall portion, and above the position corresponding to the bottom portion of the casing The lid opening drive mechanism is arranged at a position on the side with the operating force applying portion in a vertical posture in a state where at least a part of the lid opening drive mechanism enters a position corresponding to a position directly below the handle receiving portion. .

  According to the above characteristic configuration, even in the main body space existing between the outer side surface of the side wall portion of the casing and the inner side surface of the side wall portion of the outer shell portion, it is spatially expanded along with the formation of the handle receiving portion. Paying attention to the position just below the handle receiving part, the lid opening drive mechanism serving as the drive source for the lid opening operation of the container container, with at least a part thereof entering the position just below the handle receiving part, and By arranging the operating force application unit in a vertical orientation, the lid opening drive mechanism with a relatively large volume can be assembled reasonably while effectively utilizing the already formed space. Can do.

  In addition, by disposing the lid opening drive mechanism at a position above the position corresponding to the bottom of the casing in the main body space, the link member that unlocks the lock mechanism with the unlocking operation force applied from the lid opening drive mechanism. Therefore, the allowable range with respect to the dimensional variation is widened, and a stable tooling operation is possible.

  Furthermore, it is not necessary to secure a space for installing the lid opening drive mechanism in the bottom space of the main body, that is, the bottom space between the bottom wall portion of the outer shell and the bottom wall portion of the casing. Only the arrangement of other parts such as a motor and a power cord arranged at the bottom of the main body is facilitated, and an increase in product dimensions can be prevented.

  Therefore, the above-described rational improvement focusing on the position corresponding to the position immediately below the handle receiving portion in the main body space existing between the side wall portion of the casing and the side wall portion of the outer shell portion is the opening operation of the lid of the container case. It is possible to improve the stability of the tooling operation, reduce the product size, and reduce the manufacturing cost.

  According to a further characteristic configuration of the bread maker according to the present invention, the first motion transmission portion of the link member is located above the position corresponding to the bottom of the casing in the main body space, and the handle receiving portion is formed. Within the range below the corresponding position and at a position corresponding to the operating force applying portion of the lid opening drive mechanism, the link member is disposed in a lateral posture in a direction perpendicular to the pivot axis of the link member. In the point.

  According to the above characteristic configuration, a portion of the main body space that is spatially expanded with the formation of the handle receiving portion, that is, above the position corresponding to the bottom of the casing in the main body space, and the handle receiving portion. Since the first motion transmitting portion of the link member can be extended with a margin in a horizontal posture such as a horizontal posture within a range lower than the position corresponding to the formation of the link, the link from the operating force applying portion of the lid opening drive mechanism The transmission of the unlocking operation force to the first motion transmission portion of the member can be ensured, and the link length at the first motion transmission portion of the link member is increased, thereby reducing the size of the lid opening drive mechanism. However, a sufficient unlocking operation force can be applied to the lock mechanism.

  A further characteristic configuration of the bread maker according to the present invention is that the lid opening drive mechanism is attached to an attachment portion provided at a portion corresponding to the handle receiving portion on the inner side surface of the main body.

  According to the above-described characteristic configuration, the lid opening drive mechanism that is disposed between the opposing surfaces of the side wall portion of the casing and the side wall portion of the outer shell portion is provided with the main body that is spatially expanded along with the formation of the handle receiving portion. It can be easily installed with the mounting part provided using the inner surface, and there is no need to secure the space for installing the mounting part of the lid opening drive mechanism in the bottom space of the main body. It is possible to promote downsizing and manufacturing cost reduction.

  According to a further feature of the bread maker according to the present invention, the second motion transmitting portion of the link member that opens the locking mechanism is inserted into a through hole formed in a side wall portion of the casing. A link support member that is disposed in a heating chamber formed by the lid and supports the link member in a swingable manner is provided between the through hole of the casing and the insertion portion of the link member. It is in the point which is provided in the state which reduces.

  Here, in this type of bread maker, the first motion transmission portion of the link member is disposed in the main body space that exists between the opposing surfaces of the side wall portion of the casing and the side wall portion of the outer shell portion, and the second of the link member. Due to the insertion and arrangement of the motion transmitting portion in the heating chamber, a slightly larger through hole is formed in the side wall portion of the casing for inserting the second motion transmitting portion of the link member during assembly. As a result, a relatively large gap is generated between the through hole of the casing and the outer surface of the insertion portion of the link member, and the heat in the heating chamber formed in the casing is heated through the gap of the through hole. There is a risk of being released outside.

  However, according to the above characteristic configuration, the gap can be reduced by using a link support member for swingably supporting the link member. Therefore, it is not necessary to provide a special gap closing member for reducing the thickness, and the structure can be advantageous in terms of structure and manufacturing cost.

  According to a further characteristic configuration of the bread maker according to the present invention, the link member is composed of a plate member extending along a plane perpendicular to the swing axis of the link member, and the link support member includes A slit is formed into which the intermediate plate portion on the second motion transmission portion side of the link member enters, and both side edges in the width direction of the slit are smaller than the width of the through hole, and the intermediate plate portion of the link member It is in the point formed in parallel or substantially parallel to the plate surface.

  According to the above characteristic configuration, the link member is formed of a plate member extending along a plane orthogonal to the pivot axis, and thus the link member when transmitting the unlocking operation force applied from the lid opening drive mechanism to the lock mechanism. The bending deformation of the container can be suppressed, and the stability of the container operation that is the opening operation of the container container lid can be promoted.

  In addition, the link support member that supports the link member is formed with slits into which the intermediate plate portion on the second motion transmission portion side of the link member enters, and both side edges of the slit in the width direction are formed on the through holes of the casing. By forming in parallel or substantially parallel to the plate surface of the intermediate plate portion of the link member with a width smaller than the width, the gap between the through hole of the casing and the insertion portion of the link member can be efficiently reduced. The swinging of the link member can be guided at both side edges in the width direction of the slit.

  According to a further characteristic configuration of the bread maker according to the present invention, the first motion transmission portion of the link member is disposed in a lateral posture in a direction perpendicular to the swing axis of the link member, and the first motion transmission is performed. The part is formed with a detachment preventing part for restricting the contact range of the lid opening drive mechanism with the operation force applying part in the swing axis direction.

  According to the above characteristic configuration, the contact position between the first motion transmitting portion of the link member and the operating force applying portion of the lid opening drive mechanism varies in a direction perpendicular to the swing axis as the link member swings. Even so, by arranging the first motion transmission portion of the link member in a lateral orientation in a direction perpendicular to the pivot axis of the link member, the contact position variation accompanying the swing of the link member can be reliably and easily performed. Can be absorbed into.

  In addition, even when the contact position between the first motion transmission portion of the link member and the operation force applying portion of the lid opening drive mechanism varies in the swing axis direction, the operation force applying portion of the lid opening drive mechanism and the first operation Detachment can be prevented by the contact of the transmission part with the separation preventing part.

  Therefore, the operation transmission state between the operation force applying unit of the lid opening drive mechanism and the first operation transmission unit of the link member can be reliably maintained, and the stability of the container operation which is the operation of opening the lid of the container container Can be promoted.
