Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for removing dirt from an induction heating cooker that can easily and efficiently remove dirt from various cooking appliances.
[0002]
[Prior art]
In general, in cooking appliances, not only food materials but also oils and fats flowing out of the food materials and cooking oils used during cooking adhere to the cooking surface and the inside as “oil stains”. Oil stains are only attached at the initial stage, but polymerize and stick firmly over time and cannot be easily removed. For example, cooking equipment such as oven toasters and ovens has oil stains firmly stuck on the window glass or in the cabinet, and cooking equipment using induction heating or resistance heating, the dirt cannot be easily removed. For this reason, dirt is removed by using a detergent or rubbing off with an abrasive.
[0003]
[Problems to be solved by the invention]
However, such a conventional method is time consuming and inefficient because the dirt cannot be completely removed. In particular, the method of using an abrasive material may cause problems such as scratching the surface of the window glass or the top plate and reducing the mechanical strength.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described conventional problems, and to provide a method for removing dirt from an induction heating cooking appliance that easily and efficiently removes stuck dirt.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the method for removing dirt from an induction heating cooking appliance according to the present invention comprises applying or dropping an alkaline detergent on a dirt portion of an induction heating cooking appliance having a heating means , and heating the heating on the detergent. An object to be heated that is induction-heated by means is placed, and the detergent is heated by the object to be heated to remove dirt. As a result, the effect of the detergent can be maximized, and dirt can be easily and efficiently removed.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
According to the first aspect of the present invention, an alkaline detergent is applied or dripped onto a dirt portion of an induction heating cooking appliance having a heating means, and a heated object that is induction-heated by the heating means is placed on the detergent. In addition, by adopting a method for removing dirt from an induction heating cooker that removes dirt by heating the detergent with the heated body, the effect of the detergent can be maximized, and dirt can be easily and efficiently removed. Is.
[0007]
In general, a detergent has an action of emulsifying oil and changing it into a substance that is easily dissolved in water. This is governed by the temperature at the time of use, and the dirt removal performance can be enhanced by increasing the temperature at the time of use of the detergent. Therefore, the action of the detergent can be used effectively, the effect of the detergent can be maximized, and strong oil stains can be removed. In addition, when heating a detergent, the stain | pollution | contamination part of a cooking appliance is heated beforehand, and a detergent may be given on this and a detergent may be heated.
[0008]
On the other hand, the heating temperature is not particularly limited, but it is preferable to heat to 100 ° C. if possible. This is because the soil removal effect is remarkably enhanced by both the soil removal effect due to the detergent temperature and the penetration effect into the soil due to boiling.
[0009]
Further, by making the detergent alkaline, it is possible to remarkably improve the performance of removing dirt by heating. In addition, pH 9-12 is good as an optimal detergent. This is because the alkalinity is weak at pH 9 or lower and the dirt removal performance is inferior, and conversely, the alkalinity is strong at pH 12 or higher, which adversely affects the surface of the window glass and the plate, particularly the printed matter on the plate.
[0010]
According to the second aspect of the present invention, a holding body made of a porous material and holding an alkaline detergent is placed on a dirt portion of an induction heating cooking appliance having a heating means, and the object heated by induction by the heating means. in the heating body, by a soil removal method of the induction cooking device to remove dirt by heating the detergent of the holding member to suppress the movement of detergent, it can always be allowed to position the portion dirt detergent efficiently A strong oil stain can be removed. Note that the timing for holding the detergent on the holding body may be before or after the holding body is placed on the dirty portion of the cooking appliance.
[0011]
Further, by configuring the holding body as a porous body, the detergent can be efficiently held by the holding body, and the detergent can always be positioned on the dirty portion. In addition, the material used for the holding body is not particularly limited, but metal such as iron, aluminum, stainless steel, brass, etc. having excellent heat resistance and affinity with detergent, or polyethylene terephthalate, polyphenylene sulfide, polypropylene, etc. Non-metal is good. In addition, about the thing with inferiority with a detergent, you may use and perform surface treatment etc. which improve affinity.
[0012]
Further, by heating the heated body by the heating means and heating the detergent by the heated body to remove the dirt, strong oil dirt can be easily and efficiently removed by heating the heated body. .
[0013]
【Example】
An embodiment of the present invention will be described with reference to the drawings, taking an induction heating cooker as a representative example of a cooking appliance.
[0014]
Example 1
FIGS. 1-6 shows the stain removal method of the cooking appliance in Example 1 of this invention.
[0015]
In the figure, 1 is a heating means made of an induction heating coil, 2 is a plate made of crystallized glass arranged in the vicinity of the heating means 1, 2a is a dirt portion made of oil stains adhering to the plate 2, and 3 An alkaline detergent having a pH of 12 is applied or dripped onto the soiled portion 2a. The detergent 3 contains an alkali component made of water glass, a surfactant, and an abrasive made of silicon oxide. The pH of the detergent is preferably 9-12. This is because the alkalinity is weak at pH 9 or lower, and the performance of removing dirt is poor. Conversely, at pH 12 or higher, the alkalinity is strong and adversely affects the surface of a cooking appliance window glass or plate, particularly the printed matter on the plate. It is suitable.
[0016]
Reference numeral 4 denotes a heated object placed on the detergent 3, which is a cooking utensil (two-handed pan) that generates heat by induction heating. The heated body 4 has a three-layer structure of stainless steel / aluminum / stainless steel in order to ensure heat uniformity. Note that 100 cc of water 5 is placed in the heated body 4. The water to be put into the heated body 4 is to prevent the detergent 3 from generating abnormal heat due to baking when the heated body 4 is heated, and it is not necessary to stick to 100 cc. However, if it exceeds 100 cc, it takes a long time to reach the temperature necessary for heating the detergent 3, and it takes a long time to remove the dirt.
[0017]
The dirt removal method in such a configuration will be described with reference to FIG. FIG. 2 is a graph showing the heating pattern of the detergent 3, with the horizontal axis representing the elapsed time from the start of heating and the vertical axis representing the temperature change of the detergent 3. First, the heated body 4 is heated by the heating means 1 of the induction heating cooker, and the temperature of the detergent 3 is increased by the heat to 100 ° C. Thereafter, the heating means 1 is adjusted and held for 2 minutes so that the detergent 3 does not dry and solidify. Next, the to-be-heated body 4 is removed, the detergent 3 is wiped off with a wet towel, and the dirt on the dirty part 2a is wiped off. In this way, strong oil stains could be easily removed. For comparison, the detergent 3 was applied onto the soiled portion 2a, left at room temperature for 1 hour, and then wiped off with a wet towel in the same manner, so that the oil stain could hardly be removed.
[0018]
In the present embodiment, the heating pattern of the detergent 3 has been described with reference to FIG. 2, but the present invention is not particularly limited to this, and the dirt removal performance can be enhanced even with the heating pattern as shown in FIGS. 3 to 5. However, depending on the components of the detergent 3 to be used, if the detergent 3 is kept at a temperature of 100 ° C. or higher or 100 ° C. for a long time, the detergent 3 tends to solidify, and dirt removal performance may be deteriorated.
[0019]
Moreover, although the cooking utensil was used as the to-be-heated body 4 which heats the detergent 3, it is not restricted to this, As shown in FIG. 6, the two-layer clad material of stainless steel and aluminum which has heat 7 by induction heating as shown in FIG. Alternatively, the detergent plate 3 may be heated by using the dedicated hot plate 6 using the heating means 1 and the heating means 1. In order to reduce warpage during heating in the dedicated hot plate 6, a three-layer clad material of stainless steel, aluminum and stainless steel may be used.
[0020]
In order to prevent abnormal heating, a two-layer or three-layer clad material using a magnetic shunt alloy having a Curie temperature of 100 ° C. or higher and lower than 150 ° C. may be used instead of stainless steel.
[0021]
As is apparent from the above description, this embodiment is designed so that the effect can be maximized and strong oil stains can be removed by heating the detergent. In other words, the detergent has the action of emulsifying oil and changing it into a substance that is easily dissolved in water. This is governed by the temperature at the time of use, and the dirt removal performance can be improved by increasing the temperature at the time of use of the detergent. . Therefore, a strong oil stain is removed by making full use of the action of this detergent and maximizing the effect of the detergent. In addition, when heating a detergent, the stain | pollution | contamination part of a cooking appliance may be heated beforehand and a detergent may be given on this and a detergent may be heated.
[0022]
On the other hand, the heating temperature is not particularly limited, but it is preferable to heat to 100 ° C. if possible. This is because the soil removal effect is remarkably enhanced by both the soil removal effect due to the detergent temperature and the penetration effect into the soil due to boiling.
[0023]
(Example 2)
Next, FIG. 7 shows a method for removing dirt from a cooking appliance in Embodiment 2 of the present invention.
[0024]
In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. The difference is that the detergent 3 is held by a holding body 8 made of a mesh of polyethylene terephthalate having an opening of 0.5 mm and placed on the dirt portion 2a. A cooking utensil is placed on the holding body 8 as the heated body 4. As in the case of Example 1, 100 cc of water is placed in the heated body 4.
[0025]
Further, the holding body 8 may be composed of a porous body such as foam, lath net, punching, non-woven fabric or the like other than the mesh, and the structure is particularly limited as long as the detergent can be efficiently held. Not. The material used for the holding body 8 is not particularly limited, but is not limited to metals such as iron, aluminum, stainless steel, and brass, which have excellent heat resistance and compatibility with detergents, or non-polyethylene terephthalate, polyphenylene sulfide, polypropylene, and the like. Metal is good. And about the thing with inferiority with a detergent, you may use and perform the surface treatment which raises affinity.
[0026]
In such a configuration, as in Example 1, after heating the detergent 3 with the heating pattern of FIG. 2 while adjusting the heating means 1, the heated body 4 and the holding body 5 are removed, and the plate 2 is covered with a wet towel. The detergent 3 and the dirty part 2a remaining on the top are wiped off. By this method, strong oil stains could be easily removed.
[0027]
In this embodiment, since the holding body 8 is interposed between the heated body 4 and the plate 2, the detergent 3 does not protrude beyond the dirty portion 2 a during heating, and the heated body 4 does not slide. Since the phenomenon of reducing the efficiency of dirt removal is remarkably suppressed, the dirt can be removed stably.
[0028]
In this embodiment, the order in which the detergent 3 is held by the holding body 8 is not particularly limited, and the detergent 3 may be held by placing the holding body 8 on the dirty portion 2a. The holding body 8 holding the above may be placed on the dirty portion 2a.
[0029]
( Reference Example 1 )
Next, FIGS. 8-10 shows the stain removal method of the cooking appliance in the reference example 1 of this invention.
[0030]
In this reference example , the same parts as those in the first and second embodiments are denoted by the same reference numerals, and the description thereof is omitted. The difference is that, apart from the heating means 1 of the cooking appliance, a heating element 9 that is integrated on the back surface of the plate 2 by printing and generates heat by resistance heating is provided. And in part of the operation part 10 which performs various control operation of a cooking appliance, the dirt removal exclusive key 11 which controls the heat generating body 9 is installed. As a result, when the detergent 3 is heated, the heating element 9 is controlled with a pre-programmed heating power, enabling fine temperature control, further enhancing the effect of the detergent, and suppressing the abnormal temperature rise during heating to increase safety. I try to secure it.
[0031]
The operation of this reference example in such a configuration will be described. First, the dedicated key 11 is operated to heat the detergent 3 with the heating pattern shown in FIG. After the heating is completed, the detergent 3 and the dirty part 2a are wiped off with a wet towel in the same manner as in Example 1 to remove the dirt. Thus, in the method using the dedicated key 11, the detergent 3 is not accidentally heated more than necessary, and the detergent 3 is not solidified or stuck, so that the care after removing the dirt becomes easy.
[0032]
Moreover, as shown in FIG. 10, since it can control freely in the temperature range which the detergent 3 activates, the removal performance of dirt improves. In this reference example , the detergent 3 is applied directly to the soiled portion 2a. However, the present invention is not particularly limited to this, and the method using the holding body 8 described in the second embodiment may be used.
[0033]
Further, as the heating element 9, in addition to the resistance heating element by printing, a planar heating element such as a mica heater or a carbon heater may be attached. Furthermore, a heating element layer that generates heat by induction heating may be formed.
[0034]
As described above, each of Examples 1 and 2 and Reference Example 1 has been described. However, the detergent is not limited to those having a pH of 12, and is weakly alkaline or stronger by optimizing the heating temperature. But it can be used. Furthermore, although the induction heating cooker has been described as the cooking device, it is obvious that other cooking devices may be used.
[0035]
