- the weight detection unit 7 and the members connected thereto from the housing 5 are not exposed to the outside from the housing 5. Therefore, when transporting or storing the casing 5 and the support portion 6 separately, even if the casing 5 is placed, no load is applied to the weight detection unit 7 from the outside. Thereby, damage of the weight detection part 7 by an impact etc. can be prevented beforehand. As a result, a heating cooker with higher reliability can be provided.
- the configuration in which the tip of the connecting portion 17 is the lens-shaped convex portion 17a has been described as an example, but the present invention is not limited thereto.
- the tip of the connecting portion 17 may be a concave portion
- the load receiving portion 16 may be a convex portion.
- the connection part 17 and the load receiving part 16 should just be the structures which contact
- the heating cooker of the present disclosure includes a top plate on which a cooking container that stores a cooked product is placed, a heating unit that heats the cooking container, and a control unit that controls the heating unit. Furthermore, the cooking device has a top plate formed on the top plate, and is housed by placing a housing containing at least the heating unit and the control unit, a support unit for housing the housing, and a support unit placed on the opening. A mounting table and a weight detector for detecting the weight are provided. The housing is supported by the support unit via the weight detection unit at a position lower than the opening surface of the opening of the mounting table, and the weight detection unit detects the weight of the cooking container placed on the top plate. You may comprise.
- the weight detection unit is not arranged in the gap between the kitchen table that is the mounting table and the top plate. Therefore, the height of the heating cooker protruding upward from the mounting table can be kept low. Thereby, the design is improved. In addition, when handling the pan, the possibility that the pan will hit the end of the top plate is reduced. Thereby, high workability and convenience can be provided to the user.
- the housing can be supported by the support part via the weight detection part at a position lower than the opening part of the mounting table. Therefore, the height between the support portion and the top plate can be kept low.
- casing can be accommodated between the step below the level
- a weight detection unit is arranged between the housing and the support unit inside the mounting table with few height restrictions. Therefore, for example, the weight detector 7 having a high component height can be arranged. That is, a beam type load cell that suppresses a change in characteristics due to an external factor such as temperature and has a through hole with high detection accuracy can be adopted as the weight detection unit 7.
- the weight detection unit may be disposed between the housing and the support unit.
- the weight detection unit is arranged outside the casing. Therefore, when the performance of the weight detection unit is deteriorated due to long-term use, impact, or the like, it can be dealt with by replacing only the weight detection unit instead of replacing each case. That is, the cooking device can be used continuously with a simple replacement operation. As a result, a cooking device excellent in economy and workability can be realized.
- the cooking device of the present disclosure includes a housing opening provided on the bottom surface of the housing, and a connection portion that contacts the weight detection unit and the support through the housing opening.
- the weight detection unit may be disposed inside the housing, and the housing may be supported by the support unit via the connection unit.
- the weight detection unit is provided in the housing. Therefore, for example, it is difficult to cause problems such as transportation in an unpacked state in a factory and damage due to contact at the time of installation. Furthermore, the weight detection part 7 is hard to get dirty. Thereby, handling of a cooking-by-heating machine is easy, and a cooking-by-heating machine excellent in workability, such as installation, can be provided.
- the weight detection unit of the cooking device of the present disclosure includes at least a weight sensor and a load transmission unit, the support unit includes a load receiving unit at a position facing the load transmission unit, and the housing includes a load It is good also as a structure supported by a support part by contact
- the load transmission part of the heating cooker of this indication is provided with a convex part or a concave part, and a load receiving part is provided with the concave part which contacts a convex part, or the convex part which contact
- a weight detection part is supported by point contact. As a result, the weight of the object to be heated can be detected with high detection accuracy.
- the weight detection unit of the cooking device of the present disclosure has at least a weight sensor, a load transmission unit, and a connection unit or a load receiving unit, and the support unit is a load receiving unit at a position facing the connection unit, Alternatively, the connection portion may be provided at a position facing the load receiving portion, and the housing may be supported by the support portion by contact between the connection portion and the load receiving portion. Thereby, a weight detection part can be arrange
- connection part of the heating cooker of this indication may be provided with a convex part or a concave part
- a load receiving part may be provided with the concave part which contacts a convex part, or the convex part which contact
- the support part of the heating cooker of this indication may have an opening part, a hole, or a slit in a bottom face. Thereby, the retention of the liquid thing and foreign material in a support part is prevented. As a result, the cooking device can be kept more hygienic.
- the mounting table of the heating cooker according to the present disclosure may have a configuration in which a step is provided on the opening side and the support portion is mounted on the step. Thereby, the level difference between the mounting table and the top plate can be eliminated and a full flat state can be obtained. As a result, it is possible to prevent the occurrence of problems due to the collision with the object to be heated, and the design and convenience are further improved.
- the casing of the cooking device of the present disclosure may include a steel plate fixed to the top plate, and the weight detection unit may be disposed outside the bottom surface of the steel plate. Thereby, the influence on the weight detection part by the penetration
- a high weight detection unit can be provided. As a result, the weight of the object to be heated can be detected with high detection accuracy, and cooking can be performed efficiently.
- the cooking device of the present disclosure may be provided with a recess that is recessed toward the top plate on the bottom surface of the steel plate, and the weight detection unit may be disposed in the recess.
- the housing can be made thinner.
- the heating cooker of the present disclosure can ensure accuracy and reliability without affecting the weight detection unit due to the intrusion of the liquid material even if the liquid material flows out on the kitchen table which is the mounting table. Moreover, the height of the heating cooker which protrudes above a kitchen stand can be restrained low. Therefore, it can be applied to various uses of heating cookers that require high design and convenience.
