Description

  The present invention relates to a cleaning device for cleaning toilet bowls and sanitary cleaning devices.

  Conventionally, this type of cleaning apparatus is a cleaning apparatus having a drug spraying means for spraying a drug in a toilet and a human body cleaning means for cleaning a human body part, and is based on the drug spraying operation by the drug spraying means and the human body cleaning means. The human body washing operation is linked to each other (see, for example, Patent Document 1).

  FIG. 8 shows a conventional cleaning apparatus described in Patent Document 1. In FIG. This is a sanitary washing device mounted on a toilet, and as shown in FIG. 8, from the external water supply source side, a water supply unit 1, a heat exchange unit 2, a water supply flow rate adjustment unit 3, and a flow path switching unit 4 are connected. The portion from the provided flow channel switching unit 4 is divided into two channels, a toilet cleaning channel 5 and a human body cleaning channel 6. The toilet flushing flow path 5 is provided with a drug mixing unit 7 in the middle, and a toilet flushing nozzle 8 is connected to the further end. A human body cleaning nozzle 9 is connected to the end of the human body cleaning channel 6. Wash water is taken in from the outside by the water supply unit 1 and sent to the heat exchange unit 2. The washing water is warmed by the heat exchange unit 2 and sent to the feed water flow rate adjustment unit 3. The feed water flow rate adjustment unit 3 adjusts the flow rate of the cleaning water to the downstream side, and sends the adjusted cleaning water flow rate to the flow path switching unit 4. The channel switching unit 4 selectively supplies cleaning water to either the toilet cleaning channel 5 or the human body cleaning channel 6. The washing water sent to the toilet flushing flow path 5 is added with a drug when passing through the drug mixing unit 7 and then sprayed from the toilet flushing nozzle 8 onto the toilet bowl surface. The washing water sent to the human body washing flow path 6 is sent to the human body washing nozzle 9 and sprayed on the human body.

  In this cleaning apparatus, since the medicine spraying operation by the toilet cleaning nozzle 8 and the human body cleaning operation by the human body cleaning nozzle 9 are linked to each other, for example, if the setting is such that the medicine is sprayed after a certain time after the human body cleaning is completed, the human body cleaning is performed. It is said that the medicine can be automatically sprayed into the toilet without any new operation by the user simply by operating the device and washing the human body.

Further, by disposing the medicine mixing unit 7 on the downstream side of the heat exchange unit 2, the toilet bowl is washed with warm water, and the effect that the toilet bowl can be effectively cleaned with warm water is obtained. .
JP 2003-278219 A

  However, in the conventional configuration of FIG. 8, when warm water is sprayed from the toilet cleaning nozzle 8, the medicine is always mixed into the warm water from the drug mixing unit 7, so the warm water is sprayed on the toilet and the surface of the toilet is sprayed. Since the drug continues to be consumed until the temperature rises and the cleaning effect increases, the amount of the drug used increases until the dirt is sufficiently removed, and it is necessary to replenish the drug frequently.

  Moreover, since the chemical | medical agent is diluted with warm water, the effect of the chemical | medical agent may not be able to be exhibited with respect to strong stain | pollution | contamination. For this reason, the cleaning time becomes longer, and not only the amount of drug used but also energy loss increases.

  The present invention solves the above-described conventional problems, and an object thereof is to provide a cleaning device that uses a small amount of chemicals and has a high cleaning effect.

  In order to solve the above-described conventional problems, the cleaning apparatus of the present invention includes a chemical discharge unit that discharges a chemical to the surface to be cleaned, and a heating unit that increases the temperature of the surface to be cleaned. After the surface to be cleaned is heated by the means, the medicine is discharged.

  As a result, the temperature of the surface to be cleaned from which the medicine is discharged is raised, and the cleaning effect is improved.

  In the cleaning apparatus of the present invention, since the temperature of the cleaning surface on which the medicine is discharged is increased, the cleaning effect is enhanced and the amount of the medicine to be used can be reduced.

  According to a first aspect of the present invention, there is provided a medicine discharge means for discharging a medicine to at least a surface to be cleaned, and a heating means for increasing the temperature of the surface to be cleaned. By discharging, the temperature of the surface to which the drug is discharged increases, so that the cleaning effect of the drug is improved, and as a result, the amount of drug used can be reduced.

  In the second invention, in particular, since the heating means of the first invention is constituted by a heating means for directly heating the surface to be cleaned, the surface to be ejected can be directly heated. The temperature of the cleaning surface can be increased. Therefore, cleaning with a high cleaning effect can be performed with a simple configuration.

  In the invention according to claim 3, in particular, the heating means of the first invention is constituted by hot water discharge means for discharging hot water to the surface to be cleaned, and the hot water is discharged to the surface to be cleaned in advance and heated, Thereafter, the heated surface can be quickly heated and cleaned by discharging the medicine. Moreover, since there exists an effect which swells and peels a stain | pollution | contamination with warm water, the cleaning effect increases more.

  In the invention according to claim 4, in particular, the heating means of the first invention is constituted by a steam discharge means for discharging steam to the surface to be cleaned, and the surface to be cleaned is sprayed and heated in advance, and thereafter By discharging the medicine, the heated surface can be heated and cleaned more quickly. Moreover, not only the cleaning effect is enhanced by steam, but also a sterilizing effect and an antifungal effect.

  The invention according to claim 5 is an example in which the medicine ejection operation of the medicine ejection means of the third or fourth invention and the ejection operation of the heating means are interlocked. Operations such as discharging hot water or steam onto the surface to be discharged by the means and heating, or discharging hot water or steam onto the surface to be discharged again with the heating means after the medicine is discharged can be automatically linked. Therefore, efficient cleaning and rinsing operations can be performed automatically, which is easy to use.

  The invention according to claim 6 is a medicine discharge means of the third invention, in which the medicine is selectively mixed into the path of the hot water discharge means, and the surface to be cleaned is heated by the hot water discharge means. By adopting a configuration in which the medicine is mixed into the hot water and the medicine is discharged onto the surface to be cleaned, the hot water discharge and the medicine discharge can be performed in one path, so that the configuration is simplified.

  The invention according to claim 7 is provided with an atomizing means for atomizing the medicine in any one of the first to sixth inventions, and when the medicine is discharged, the medicine is finely atomized. By discharging, the drug can be discharged thinly and uniformly on the non-cleaning surface. Accordingly, the cleaning efficiency of the drug is increased, and the amount of the drug used can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.
