Description

  The present invention relates to a cleaning composition that can remove dirt adhered to the inside of a washing tub, and more specifically, dirt can be easily and quickly removed using a hydrogen peroxide-based cleaning agent. It is what I did.

  In general, mold, soap residue, scales, sebum components, and the like adhere to the inside of the washing tub after a long period of use. For this reason, it is preferable to periodically wash the washing tub so as to prevent dirt from adhering to the laundry or to prevent a strange odor from being transferred to the laundry.

  As a cleaning agent for cleaning such a washing tub, a chlorine-based cleaning agent such as sodium hypochlorite has been conventionally used. However, such a chlorine-based cleaning agent has a problem that considerable care must be taken in use in order to generate chlorine gas (Patent Document 1).

  On the other hand, a method for cleaning a washing tub using a hydrogen peroxide-based cleaning agent has also been proposed (Patent Document 1). Such a cleaning agent oxidizes and decomposes dirt with hydrogen peroxide generated by dissolving in water and peels the dirt from the washing tub.

JP 2001-3090 A

  However, when this hydrogen peroxide-based cleaning agent is used, there is a large dependence on the reactivity depending on the water temperature. Therefore, when water at room temperature is used, there is a problem that the reaction must be waited for a long time. On the other hand, organic hydrogen peroxide is known to have high reactivity at low temperatures, but it is handled as a hazardous material, and thus has a problem that it is not suitable for use in ordinary households.

  Then, an object of this invention is to provide the cleaning composition which enabled it to wash | clean a washing tub etc. easily and in a short time, without using a dangerous material.

  That is, in order to solve the above-mentioned problem, the present invention is provided separately from sodium percarbonate to be poured into water filled in a washing tub or the like, and the sodium percarbonate. The catalase is provided.

  In this way, sodium percarbonate can be reacted in an aqueous solution to remove soap residue and the like with sodium carbonate, and then the reaction can be promoted with catalase, so Can be sterilized and removed.

  Moreover, in such invention, a catalase is mix | blended in the range of 4-7 weight percent by weight with respect to sodium percarbonate.

  When blended at such a ratio, even when catalase is added to an aqueous sodium percarbonate solution at room temperature, the dirt can be lifted by the optimum amount of foam, and the foam spouts out of the washing tub. There is no such thing.

  When such a cleaning agent is used, sodium percarbonate is put into the washing tub, and then the drum of the poured washing tub is rotated for a predetermined time, and then 4 to 7 weight by weight with respect to the sodium percarbonate. Rotate the drum with a percentage of catalase.

  If it does in this way, after removing the soap residue in a washing tub with sodium percarbonate, the mold which was concealed inside can be sterilized and removed. Moreover, since the ratio of catalase is 4 to 7% by weight with respect to sodium percarbonate, it is possible to generate an optimum amount of bubbles to raise the dirt, and to scavenge the raised dirt and drain it. Will be able to.

  According to the present invention, sodium percarbonate to be put into water filled with an object to be cleaned, and a catalase which is provided separately from the sodium percarbonate and can be thrown in later, Soap can be removed with sodium carbonate by reacting sodium percarbonate in aqueous solution, and then the mold is sterilized and removed with hydrogen peroxide and oxygen by promoting the reaction with catalase. Will be able to.

The figure which showed the state of the dirt adhering to the inner side of the washing tub in this invention The figure which shows the injection | throwing-in method of the cleaning agent in the same form The figure which showed the process of washing the washing tub in the form

  Hereinafter, an embodiment of the present invention will be described.

  The cleaning composition according to this embodiment is configured to be able to clean a washing tub 1 as shown in FIG. 2, a bath tub, tableware, a water bottle, or the like that can be filled with water. A sodium carbonate hydrogen peroxide adduct (hereinafter referred to as “sodium percarbonate”) in which sodium and hydrogen peroxide are mixed at a molar ratio of 2: 3 and catalase are separately provided.

  This sodium percarbonate is a water-soluble colorless solid, and decomposes into sodium carbonate and hydrogen peroxide in an aqueous solution. Due to the decomposed sodium carbonate, the aqueous solution is weakly basic, while hydrogen peroxide has oxidizing power. Since hydrogen peroxide generated by this decomposition has an oxidizing power like hydrogen peroxide solution, it can function as a bleaching agent, disinfectant, and deodorant. Further, this hydrogen peroxide is decomposed into water and oxygen only by leaving it in an aqueous solution, and sodium carbonate is almost harmless, so that the influence on the environment can be reduced. This sodium carbonate has a function as an alkali assistant for soap, wraps and precipitates dirt, plays a role of making the cleaning liquid alkaline and converting the fats and fatty acids of the dirt into soap, and an aqueous solution based on alkali buffering action. For maintaining the pH at a suitable pH. This sodium percarbonate has a granular shape and is put into the washing tub 1 so as to be sprayed to improve the reactivity.

  Catalase, on the other hand, is an enzyme that catalyzes the reaction that disproportionates hydrogen peroxide into oxygen and water, and is extracted and purified from animal livers, kidney-like organs, red blood cells, plants, and microorganisms. . When added to sodium percarbonate, this catalase can accelerate the decomposition rate of sodium percarbonate and generate a large amount of oxygen. As a form of this catalase, a liquid form is used to promote the reaction, and it is accommodated in a container different from the previous sodium percarbonate.

  The amount and component ratio of such sodium percarbonate and catalase are preferably as follows.

  For example, when washing a standard 9-liter washing machine for general households (when the standard specification water volume is about 100 liters), 370 to 430 grams of sodium percarbonate can be introduced. On the other hand, the amount of catalase is set to an amount that can be washed in a short time and generates an optimum amount of bubbles. That is, if the amount of catalase is small, not only will washing take time, but the amount of foam will decrease and the peeled dirt will settle in the washing tub, and the dirt will again be inside the washing tub 1. There is a possibility of adhering. On the other hand, when the amount of catalase is excessively large, a large amount of foam is generated, and the foam may be ejected from the opening portion of the washing tub 1 shown in FIG. For this reason, the amount of catalase is prepared in a ratio of 4 to 15 percent by weight with respect to sodium percarbonate. When washing the washing tub 1, if the drum 2 is rotated while being washed, the reaction is further promoted by the rotation of the drum 2 and bubbles are generated. Therefore, the weight ratio is set within the range of 4 to 7 weight percent. deep. That is, when washing the washing tub 1 of a 9-liter washing machine, it can be put in a range of 15 to 30 grams. About the amount of this catalase, you may make it throw into the washing tub 1 adjusting suitably with water temperature, for example, when wash | cleaning the washing tub 1 using the remaining hot water of a bath, the amount of catalase is decreased. You may do it.

  Next, a method of cleaning the washing tub 1 using such a cleaning composition will be described with reference to the process diagram of FIG. As shown in FIG. 1, mold is generated on the inside of the washing tub 1 and the surface of the drum 2 in the washing tub 1, and the soap scum adheres to the mold so as to cover the mold. It shall be.

  When washing such a washing tub 1, after confirming that there are no clothes etc. in the washing tub 1, as shown in FIG. 2, it throws in so that the powder of sodium percarbonate 5 may be sprayed (step). S1). In this state, water is supplied to a high water level (step S2), and only the “washing” course is set, and the drum 2 is rotated for about 15 minutes (step S3). When performing this water supply, you may make it use the remaining hot water of a bath.

  Then, by the action of sodium carbonate decomposed with water, soap scum and sebum components adhering to the washing tub 1 can be removed, and since the drum 2 is rotated and used, the power of water is also utilized. The dirt is forcibly peeled off (step S4). As described above, the heavyly-separated matter is deposited in the washing tub 1 and the lighter one and the one adhering to the bubbles are lifted.

  Next, the rotation of the drum 2 is stopped in a state where water is stored (step S5), and the catalase 6 at a ratio of 4 to 7 weight percent with respect to the sodium percarbonate 5 is added (step S6). Then, again, the “washing” course is set and the drum 2 is rotated, and the drum 2 is rotated for about 5 minutes (step S7).

  Then, the decomposition of the sodium percarbonate 5 is accelerated by the action of the catalase 6 and is rapidly decomposed into sodium carbonate and hydrogen peroxide. The action of hydrogen peroxide and oxygen makes it possible to bleach mold, disinfect and deodorize. In addition, a large amount of oxygen bubbles are generated by the reaction with hydrogen peroxide in this way, so that the dirt removed and precipitated by sodium carbonate can be lifted, and the dirt can be removed from the surface of the water with a net. (Step S8). At this time, if the amount of foam is too small, the dirt cannot be lifted, and conversely, if the amount of foam is too large, the dirt cannot be efficiently screened by being hidden behind the spouted foam. In this embodiment, since catalase is blended at a ratio of 4 to 7 percent by weight, it becomes possible to remove dirt from the surface of the water with a net (step S9).

  After removing the dirt in this way, “rinse”, “drainage”, and “dehydration” can be performed at a high water level (step S10).

  The washing tub 1 can be used in both a vertical washing machine and a drum washing machine, but in the case of a drum washing machine, a catalase can be introduced by opening the door halfway. Water should be poured at the “lowest water level”.

  Thus, according to the above-described embodiment, sodium percarbonate 5 that is put into the water filled in the washing tub 1 and catalase 6 that is provided separately from the sodium percarbonate 5 and can be put in later. Therefore, sodium percarbonate 5 can be reacted in an aqueous solution to remove soap residue with sodium carbonate, and then the reaction is promoted with catalase 6 so that it is covered with soap residue. The mold can be sterilized and removed.

  Further, since catalase 6 is blended in a weight ratio of 4 to 7 weight percent with respect to sodium percarbonate 5, when catalase 6 is added to a sodium percarbonate aqueous solution at room temperature, an optimum amount is obtained. As a result, the dirt can be lifted by the foam, and the foam is not ejected from the washing tub 1.

  Further, sodium percarbonate 5 is poured into the washing tub 1 and water is poured. After that, the drum 2 of the washing tub 1 is rotated for a predetermined time, and then a catalase having a weight ratio of 4 to 7 weight percent with respect to the sodium percarbonate 5. Since the drum 2 is rotated by inserting 6, the soap residue in the washing tub 1 is removed by sodium carbonate, and then the mold hidden inside can be sterilized and removed. Moreover, since the ratio of catalase 6 is 4 to 7% by weight with respect to sodium percarbonate 5, it is possible to generate an optimum amount of bubbles to raise the dirt, and after scooping up the raised dirt. It will be possible to drain.

  In addition, this invention is not limited to the said embodiment, It can implement in a various aspect.

  For example, in the above embodiment, the case where the washing tub 1 is washed has been described as an example. However, the washing composition can also be used for washing the bath tub.

  When washing the bath, adjust the water level so that it is 5-10 cm above the circulation port of the bathtub, and put sodium percarbonate powder near the circulation port. At this time, if it is necessary to wash the bath chairs and bowls, put them together in the bathtub.

  Then, the additional cooking temperature is set to 40 to 43 ° C. and the additional cooking is performed. After about 15 minutes, the catalase liquid is put in the vicinity of the circulation port and the mixture is stirred with a basin or the like. At this time, if additional cooking is stopped, additional cooking is performed for about 5 minutes, and then drainage or washing is performed. In addition, in order to rinse the inside of the circulation port, the water is filled up to about 5 cm above the circulation port, followed by additional cooking and drainage, and then washed with a shower to remove the slime.

  In addition to washing the bath, it can also be used for washing heat pump water heaters, tableware, water bottles, and the like.

  Further, in the above embodiment, sodium percarbonate is poured into the washing tub 1 and then the water is poured, but conversely, sodium percarbonate may be poured into the washed tub 1.
