Description

  The present invention relates to a protective sheet for an electromagnetic cooker that is installed on a top plate of an electromagnetic cooker and can also be used for cleaning.

In recent years, an electromagnetic cooker has rapidly become popular in the home due to the excellent features of safety and high efficiency and the advancement of power electronics technology.
The electromagnetic cooker is safe because it can be cooked without using a flame, but since the cookware installed and heated on the top plate contains heated cooked items, oil, etc., When spilling or the like occurs, the surface of the top plate becomes dirty. In addition, since the top plate is heated to a high temperature by receiving heat from the cooking utensil, there is a risk of burns when the human body comes into contact with the human body after cooking as well as during cooking.
For this reason, various protection sheets installed on the top plate have been proposed for the purpose of protecting the top plate of the electromagnetic cooker from dirt and the like accompanying cooking and preventing the risk of burns and the like.

Conventionally, a protective sheet made of a heat-resistant material that does not block eddy currents generated by an electromagnetic cooker is known as a sheet installed on the top plate of the electromagnetic cooker (see Patent Document 1).
Further, it is a dirt prevention mat used between the top plate of the electromagnetic cooker and the bottom of the pan heated by the electromagnetic cooker, and has a circular donut shape made of an inorganic material having permeability of magnetic field lines. An anti-stain mat for an electromagnetic cooker having a thickness of 4.6 mm or less is known (see Patent Document 2).

Registered Utility Model No. 3111559 JP 2004-79513 A

Since the protective sheet described in Patent Document 1 is laid on the top plate of an electromagnetic cooker, and a cooking utensil such as a pan is installed on the protective sheet, the cooking utensil does not adhere to the top plate, and the top There will be an interval corresponding to the thickness of the protective sheet between the plate and the cooking utensil.
When the distance between the top plate and the cooking utensil is increased, the efficiency of induction heating is lowered, which is not preferable from the viewpoint of power saving and environmental protection.
The relationship between the interval between the top plate and the cooking utensil and the heating time is disclosed in FIGS. 4 and 5 of Patent Document 2, but it is preferable that the interval is small. For this reason, the protective sheet described in Patent Document 2 is formed to be thin, and further formed into a donut-shaped flat plate having an outer diameter substantially equal to or slightly larger than that of the electromagnetic cooker.

In addition, the protective sheet described in Patent Document 1 is preferably a laminated structure of two or three heat-resistant sheets, and there is a problem that it is difficult to provide a low-cost protective sheet.
Moreover, when a special heat-resistant material is used for this type of protective sheet, it is necessary to treat the protective sheet as industrial waste.

  The present invention has been made in view of the above circumstances, can prevent the top plate of the electromagnetic cooker from being soiled, can wipe and clean the cooking utensil and the top plate after use, and An object is to provide a protective sheet that does not cause a decrease in heating efficiency.

(1) In order to solve the above-mentioned problems, the present invention is an electromagnetic cooking characterized in that it is installed and used on a top plate of an electromagnetic cooker and is composed of a sheet body having water absorbency or oil absorbency. It relates to a protective sheet for dexterity.
(2) In order to solve the above-mentioned problem, the present invention has a through hole formed in a part of the sheet body that is equal to or slightly larger than the outer diameter of the bottom of a cooking utensil such as a pan or a pan used in an electromagnetic cooker. It is characterized by that.

(3) In the present invention, the sheet body is preferably made of paper.
(4) In the present invention, it is preferable that one or a plurality of cutout holes with cutout perforations having a larger outer diameter than the through holes are formed around the through holes formed in the sheet body. .
(5) In the present invention, a plurality of cut hole portions with perforations for cutting having a larger outer diameter than the through holes are formed around the through holes formed in the sheet body. In the perforation part, it is preferable that the cutting strength of the inner perforation part is lower than the cutting strength of the outer perforation part.
(6) In the present invention, it is preferable that a plurality of perforations for cutting or folding are formed on the sheet body.

  According to the present invention, by laying the sheet body on the top plate of the electromagnetic cooker and using it during cooking, water and oil can be introduced to the surroundings during cooking from cooking utensils such as pots and pans installed on the sheet body. Even if scattered, the sheet main body absorbs these water and oil, so that the upper surface of the top plate is not soiled with water, oil or cooked food. Further, even if water or oil splashed from the cooking utensils adheres to the top plate, these stains can be wiped off by the sheet body during cooking or after cooking, and the top plate can be cleaned. If the upper surface of the top plate is covered with the sheet body, it is possible to prevent the heated top plate from causing a burn.

In the present invention, when a through-hole is formed in the seat body that is equal to or larger than the cooking utensil, the cooking utensil can be installed directly on the top plate and used, so the magnetic field lines of the electromagnetic cooker work efficiently on the cooking utensil. The cooking utensil can be used with good heating efficiency. And even if water, oil, a cooked product, etc. scatters on the sheet main body outside cooking utensils during cooking, the sheet main body absorbs these, so that the top plate is not soiled. Further, even if water or oil splashed from the cooking utensils adheres to the top plate, these stains can be wiped off by the sheet body during cooking or after cooking, and the top plate can be cleaned.
When the sheet main body is made of paper, the sheet main body can be easily discarded as burnable garbage after use.

  If the sheet body is provided with a through hole and a perforation part with a perforation part is provided around the perforation, the sheet main body is aligned along the perforation part according to the size of the cooking utensil to be used. By cutting out a part, it is possible to form a cutout hole having a different size, so that a cutout hole having an appropriate size can be obtained according to the size of the cooking utensil. Therefore, it is possible to provide a protective sheet that can be applied to a plurality of sizes of cooking utensils with a single sheet body.

  In the present invention, if a plurality of perforations for cutting or folding are formed in the sheet body, the top plate can be separated into a size suitable for cleaning the top plate by cutting along the perforations. It is possible to clean using a sheet main body separated into a size that is easy to handle after the cooking. Further, by folding the sheet main body along the perforation, it can be folded into a size that is convenient for carrying and can be stored in a bag of a suitable size at the time of sale and displayed on a product shelf or the like.

Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a state in which a protective sheet according to a first embodiment of the present invention is installed on a top plate of an electromagnetic cooker. A top plate 2 is provided on a base-shaped electromagnetic cooker 1, A protective sheet 3 having a size covering the entire top surface of the top plate 2 is laid on the top plate 2.

The protective sheet 3 includes a sheet body 3a having a rectangular shape in plan view shown in FIG. 2, and a circular through hole 3b is formed in a part of the sheet body 3a. The through-hole 3a of the protective sheet 3 of the present embodiment is a circular hole having the same diameter as or slightly larger than the diameter of the bottom 5a of the cooking utensil 5 such as a pan or frying pan used in the electromagnetic cooker 1. A slightly larger diameter circular hole means that the hole is a circular hole that is several mm to several cm larger than the outer shape of the cooking utensil 5. When the cooking utensil 5 has a circular shape, the diameter may be as large as the above-described range. When the cooking utensil 5 has an elliptical shape or a rectangular shape, the periphery is preferably large as described above. Or when applying to a frying pan etc. with a round shape (R) at the corner portion, it is a rectangular through-hole with a round shape with a round shape at the corner portion.
In addition, since there are many frying pans and pans having outer diameters of 15 cm, 20 cm, and 24 cm for general households, it is preferable to form through holes 3a corresponding to these. When dealing with frying pans and pans of various sizes with a single protective sheet 3, the protective sheet of the third embodiment described later can be applied.

The protective sheet 3 is made of, for example, heat-resistant paper products (including pulp products such as Japanese paper, paper towels, newspapers, and non-woven fabrics), and is made of a material that absorbs moisture and oil.
Here, the heat resistance means a property that is stable at least with respect to a temperature at which the electromagnetic cooker 1 is exposed. Further, the sheet may be in any form such as a film shape or a braided shape. The outer shape of the protective sheet 3 is not particularly limited, but may be any shape such as a square shape, a rectangular shape, a circular shape, an elliptical shape, or a polygonal shape, and preferably covers a necessary region of the top plate 2 of the electromagnetic cooking device 1. . In the embodiment shown in FIG. 1 and FIG. 2, the top plate 2 is formed in a rectangular shape so as to cover the entire top surface. However, the size covers about half of the top plate 2 or covers a part of the top plate 2. It may be a size. The protective sheet 3 may have a single layer structure or a multilayer structure such as two layers, three layers, four layers or more.

  In order to lay the protective sheet 3 on the top surface of the top plate 2 and prevent it from moving, it is preferable to provide attachment members at corners and peripheral parts of the protective sheet 3. Examples of the attachment member include a magnet piece, a double-sided tape, a hook-and-loop fastener, a hook member, and the like, but are not limited thereto.

When the cooking utensil 5 is heated using the electromagnetic cooker 1 and the contents of the cooking utensil 5 are heated and cooked, the contents of the cooking utensil 5 such as water, oil, cooking, etc. are blown outside the cooking utensil 5. It may spill or scatter. Here, since the protective sheet 3 is laid on the top plate 2 and these scattered matters are deposited on the protective sheet 3, the top plate 2 is directly soiled with water, oil, cooked food, or the like. There is nothing. Temporarily, a small amount of water, oil, cooked food or the like that partially scatters or spills on the edge side of the through hole 3b of the protective sheet 3a may reach the top plate 2. However, after cooking or after the temperature of the top plate 2 has dropped, the cooking utensil 5 can be removed from the top plate 2 and wiped and cleaned using the protective sheet 3.
Moreover, when cooking, since the bottom part 5a of the cooking utensil 5 is installed directly on the top plate 2 via the through-hole 3a, the heating efficiency of the cooking utensil 5 by the electromagnetic cooker 1 does not fall.

  Since the protective sheet 3 laid on the top plate 2 can be easily replaced, when other cooking is performed using other cooking utensils or cooking utensils of different sizes, the protective sheet 3 is replaced with a new one. Just move on to other cooking tasks.

FIG. 3 shows a state in which the protective sheet according to the second embodiment of the present invention is installed on the top plate of the electromagnetic cooker and the counter of the sink, on the top plate 2 of the electromagnetic cooker 1 and adjacent thereto. A protective sheet 8 is laid on the counter 7 of the sink 6 to be laid. In FIG. 3, reference numeral 9 indicates a water faucet, and reference numeral 10 indicates a sink formed on the sink 6.
The planar shape of the protective sheet 8 of the second embodiment is shown in FIG. 4, but a bent portion 8b that can be folded in two is formed in the center of the folded sheet body 8a. A circular through hole 8c is formed on the side close to one long side of the protective sheet 8 along the bent portion 8b. In this embodiment, since the bent portion 8b is formed so as to cross the central portion of the through hole 8c, when the sheet body 8a is folded in half, the through hole 8c is folded back into a semicircular shape.
And the protective sheet 8 is laid so that it may straddle on the top plate 2 and the counter 7, the cooking utensil 5 is directly installed on the top plate 2 through the through-hole 8c, and a part of the protective sheet 8 is the counter 7 Covers the top surface.

As shown in FIG. 3, if a protective sheet 8 is laid from the top plate 2 of the electromagnetic cooker 1 to the counter 7 of the sink, a cutting board is installed on the protective sheet 8 on the counter 7, and vegetables and meat The food can be cooked by cutting the ingredients such as these, transferring them into the cooking utensil 5 and heating them.
In this case, since the protective sheet 8 covers the counter 7 as well, the counter 7 can be made difficult to get dirty during cooking. For example, when a tableware such as a plate or a food in the middle of processing is installed on the counter 7 after cooking, the top of the counter 7 is not soiled with the food.
In addition, the operational effects such as the point that the top plate 2 is not soiled and the top plate 2 can be cleaned are the same as those of the protective sheet 3 of the first embodiment.

FIG. 5 shows a protective sheet according to a third embodiment of the present invention. A protective sheet 10 according to the third embodiment includes a sheet body 10a having the same shape and the same material as that of the first embodiment, and a part thereof. The point that the circular through-hole 10b is formed is the same structure as the protective sheet 3 of the first embodiment.
In the sheet main body 10a of the third embodiment, a circular first cut-out hole portion 10c and a second cut-out hole portion 10d having outer diameters sequentially larger than the through-hole 10b are concentrically formed around the through-hole 10b. The point that was formed is different. The first cutout hole portion 10c is larger than the outer shape of the through hole 10b, and is partitioned by a perforation portion 10e constituting the first cutout hole portion 10c. The second cut-out hole portion 10d has an outer shape larger than that of the first cut-out hole portion 10c, and is partitioned by a perforation portion 10f constituting the second cut-out hole portion 10d.

In the sheet main body 10a, the first cutout hole 10c can be easily cut out with fingers along the perforated part 10e, and a through hole having a larger diameter than the through hole 10b can be formed. Compatible with cooking utensils.

If it is the protection sheet 10 of 3rd Embodiment shown in FIG. 5, it can respond to the cooking utensils of several types of magnitude | sizes from which a diameter differs, and has the characteristic that versatility is high.
In addition, the number of the cut-out holes formed in the protective sheet 10 is not limited to two, and a plurality of three or more cannot be used. A larger number of cut-out holes can accommodate a larger size of cooking utensil, but if the number is too large, it becomes difficult to cut out, so it is preferable to provide an appropriate number of cut-out holes.
For example, since there are many frying pans and pans having outer diameters of 15 cm, 20 cm, 24 cm, and 30 cm for general households, it is preferable to form through holes 3a corresponding to these. In the third embodiment, a through hole 10b is formed for a 15 cm frying pan or pan, a first cutout portion 10c is provided for a 20 cm frying pan or pan, and a second for a 24 cm frying pan or pan. By providing the cutout hole 10d, it is possible to provide the protective sheet 10 that can be applied to frying pans and pans of main sizes for general household use. Also, a 20 cm through hole 10 b, a 24 cm first cut hole 10 c, and a 30 cm second cut hole 10 d may be provided so that 20 cm, 24 cm, and 30 cm through holes can be formed. Good.

In the protective sheet 10 shown in FIG. 5, the interval and size of the perforations 10e and 10f may be the same interval or different intervals. Cutting is easier when the interval between the perforations is reduced or when the perforation is increased. There is a standard size for cooking utensils, and in general households, there are not many types of pans and pans to be used, and many types are used only. For example, as mentioned above, 15 cm, 20 cm, and 24 cm frying pans and pans can be exemplified. In the cooking utensils of a size often used as described above, the perforation of the perforation corresponding to the cooking utensil of the most frequently used is configured as the perforation that is most likely to be cut, and cooking of the size most frequently used The perforation of the perforation corresponding to the utensil is configured as the second perforation, and the perforation of the perforation corresponding to the third most frequently used cooking utensil is the third perforation. Can be configured.
By comprising in this way, the easy-to-use protective sheet 10 which can easily perforate the most frequently used cooking utensils can be provided.

  Alternatively, in the perforated portions arranged concentrically, the perforated portion on the inner peripheral side can be sequentially cut out more easily than the perforated portion on the outer peripheral side. In this case, when the perforation portion on the inner peripheral side is cut off, a configuration in which the target perforation portion can be easily cut without breaking the perforation portion on the outer peripheral side can be provided.

FIG. 6 shows a protective sheet according to a fourth embodiment of the present invention. The protective sheet 20 of the fourth embodiment includes a sheet body 20a having the same shape and the same material as the first embodiment, and a part thereof.
