Description

  The present invention relates to a cooking device, and more particularly to its structure.

  When cooking a highly viscous liquid such as miso soup, there is a so-called bumping phenomenon in which the contents (cooked food) suddenly pop out from a pan or the like. This phenomenon is caused by the momentary generation of large evaporation energy of the contents. At this time, the contents are not only jumped upward, but are also projected to the bottom of the pot, so that the pot is placed. A large impact force is applied to the top plate of the cooking device. However, the conventional top plate of a general cooking device has a structure in which the four sides are fixedly supported and the central portion can freely vibrate (for example, Patent Document 1).

Japanese Patent Laid-Open No. 2-78176

The conventional top plate with the four sides fixed and the central part freed, when a bumping phenomenon occurs during cooking, the top plate acts like a spring by the impact force on the top plate, There was a risk of jumping up the food.
This invention responds to the above-mentioned problem, and suppresses the bending of the top plate when an impact due to bumping is applied to the top plate, or reduces the bending speed of the top plate, so The purpose of the present invention is to provide a cooking device that can be used in a smaller scale and can be used more safely than before.

FIG. 1 is an explanatory view of a bumping phenomenon in a heating cooker. As shown in FIG. 1, when a bumping phenomenon occurs, a jet power that jumps upward and an impact force toward the bottom of the pan 11 act on the food 11 in the pan 10. Since such a force is generated, the top plate is greatly displaced up and down in a conventional cooking device that does not take measures against the bumping phenomenon.
Corresponding to this, a buffer mechanism for absorbing an impact applied to the top plate is provided on the surface facing the top plate on the lower side or the upper side of the top plate. In the following embodiments, specific configurations for suppressing the displacement of the top plate at the time of a bumping phenomenon will be sequentially shown.
FIG. 2 is a comparison diagram of the displacement of the top plate when a bumping phenomenon occurs between the conventional cooking device and the cooking device according to the embodiment of the present invention. In FIG. 2, the solid line waveform represents the displacement of the top plate without countermeasures against bumping, and the broken line waveform represents the displacement of the top plate according to the embodiment of the present invention.

Reference Form FIG. 3 is a configuration diagram of a cooking device showing a reference form of the present invention. The heating cooker includes a casing 1, a top plate 2 on which a cooking pan 10 and the like disposed on the upper part of the casing 1 are placed, and a heating unit that heats the cooked food 11 disposed inside the casing 1. (For example, induction coil) 3 and a heating part support spring 4 that supports the heating part 3 are provided. Here, the top plate 2 is fixed to the upper surface of the side wall of the housing 1.
One shock absorber 5 is disposed in the lower central portion of the top plate 2 so as to face the top plate 2. As the shock absorber 5, various types such as a hydraulic type, a pneumatic type, and a spring type may be appropriately selected and employed (this is the same in the following embodiments). In this specification, the pan 10 and the cooked food 11 are also called heated objects.
When a bumping phenomenon occurs in the cooking device and an impact force acts on the top plate 2, the impact force acting on the top plate 2 is converted into heat or the like in the shock absorber 5 as shown in the lower part of FIG. 3. Absorbed. However, the bottom plate of the housing 1 has a rigidity capable of receiving an impact force applied to the top plate 2.
Thereby, since the downward displacement speed and the amount of displacement of the top plate 2 are reduced and the reaction force to the pan 10 placed on the top plate 2 is reduced, the jumping up of the pan 10 and the cooked product 11 is suppressed, It becomes possible to prevent the food 11 from jumping out of the pan 10.

FIG. 4 is a block diagram of a heating cooker showing Embodiment 1 of the present invention. The heating cooker includes a casing 1, a top plate 2 on which a cooking pan 10 and the like disposed on the upper part of the casing 1 are placed, and a heating unit that heats the cooked food 11 disposed inside the casing 1. (For example, induction coil) 3 and a heating part support spring 4 that supports the heating part 3 are provided.
A plurality of shock absorbers 5 (two in this example) are arranged below the top plate 2 so as to face the top plate 2. The top plate 2 is supported by these shock absorbers 5 and is not fixed to the outer periphery of the housing 1. Two or more shock absorbers 5 may be arranged, but it is preferable to arrange them in point symmetry with respect to the center of the top plate 2.
When a bumping phenomenon occurs in the cooking device and an impact force acts on the top plate 2, the entire top plate 2 is displaced up and down by the shock absorber 5 as shown in the lower part of FIG. That is, unlike the case of FIG. 3, since there is no reaction force that is received by the fixed portion of the top plate 2 with respect to the impact, the impact can be reliably absorbed by the entire top plate 2, and the reaction from the top plate 2 to the pan 10. The power can be further reduced. In this case, however, the bottom plate of the housing 1 has a rigidity capable of receiving an impact force applied to the top plate 2.
Thereby, since the downward displacement speed and the amount of displacement of the top plate 2 are reduced and the reaction force to the pan 10 placed on the top plate 2 is reduced, the jumping up of the pan 10 and the cooked product 11 is suppressed, It becomes possible to prevent the food 11 from jumping out of the pan 10.
