Description

The present invention relates to a bathroom cleaning device.

Specific examples of the bathroom cleaning device are those described in Patent Documents 1 and 2.
In the bathroom cleaning devices described in these documents, for example, a cleaning nozzle is attached to the bottom of the bathtub, and the detergent solution can be sprayed from the cleaning nozzle to the inner surface of the bathtub. As an aspect of spraying the detergent solution on the inner surface of the bathtub, a plurality of detergent solution spraying operations are intermittently and repeatedly performed over a plurality of interval periods. By spraying the detergent solution in such an manner, it is possible to permeate the detergent solution into dirt such as sebum on the inner surface of the bathtub during each interval period, and enhance the effect of decomposing and removing the dirt.

However, in the above-mentioned prior art, there is still room for improvement as described below.

That is, in order to improve the cleaning action of the bathtub by the detergent solution within a limited time, the detergent solution is applied to the inner surface of the bathtub while shortening the period during which a large amount of the detergent solution is not sprayed on the inner surface of the bathtub. It is desired to lengthen the period in which a large amount of spray is applied. However, in the above-mentioned prior art, the length of the interval period set between each detergent liquid spraying operation is fixed. Therefore, it is difficult to clean the bathtub in a manner in line with the above-mentioned request, and there is still room for improvement in obtaining an excellent cleaning action.

Japanese Unexamined Patent Publication No. 2002-34812 Japanese Patent No. 4822127

The present invention has been conceived under the above-mentioned circumstances, and it is an object of the present invention to provide a bathroom cleaning device capable of obtaining a cleaning ability superior to that of the conventional one.

In order to solve the above problems, the following technical means are taken in the present invention.

The bathroom cleaning device provided by the present invention is provided with a cleaning nozzle capable of spraying a detergent solution toward a bathroom cleaning target, and a plurality of detergent solution spraying operations by the cleaning nozzle can perform a plurality of interval periods. A bathroom cleaning device that is intermittently repeatable through the bathroom cleaning apparatus, wherein at least one of the plurality of interval periods is larger than the other interval period of the previous period. It is characterized by being lengthened.

According to such a configuration, it is possible to shorten the period in which the cumulative amount of the detergent solution is sprayed to the cleaning target to be small, and to lengthen the period in which the cumulative amount of the detergent solution to be sprayed thereafter is large. Therefore, within a limited time, the cleaning effect of the detergent solution can be sufficiently exerted, and a cleaning action superior to that of the prior art can be obtained.

In the present invention, preferably, among the plurality of interval periods, the length of each interval period from the beginning to a predetermined order is shorter than the length of each subsequent interval period.

According to such a configuration, it is possible to accurately shorten the period in which the cumulative amount of the detergent solution is sprayed to the cleaning target is small and lengthen the period in which the cumulative amount of the detergent solution is large.

In the present invention, preferably, the length of each of the plurality of interval periods is configured to monotonically increase as the number of executions of the detergent liquid spraying operation increases.
Here, the monotonous increase is a monotonous increase in a broad sense, and when the length of the interval period is a sequence of T _n , as the number of executions of the detergent liquid spraying operation increases, T ₁ ≤ T ₂ ≤ T ₃ ... It means a monotonous increase in relation to it, and includes the case where the amount of increase in the interval period is zero. That is, it is a concept that the interval period does not become long and may remain constant in some cases.

Even in such a configuration, it is possible to accurately shorten the period in which the cumulative amount of the detergent solution to be sprayed to the cleaning target is small and lengthen the period in which the cumulative amount of the detergent solution is large.

In the present invention, preferably, the length of the plurality of interval periods can be changed according to the temperature of the detergent solution, the room temperature of the bathroom, the amount of the detergent solution sprayed, or a switch operation by the user.

According to such a configuration, the flexibility is excellent, and it is more preferable in enhancing the cleaning effect by the detergent solution.

In the present invention, preferably, after the operation of spraying the detergent liquid a plurality of times is completed, hot water for rinsing is sprayed from the washing nozzle to the cleaning target, and the detergent is sprayed a plurality of times. The interval period from the end of the liquid spraying operation to the start of the spraying of the hot water for rinsing is set to be longer than the longest interval period when the multiple detergent liquid spraying operations are executed. ..

According to such a configuration, it is possible to take a long period (the period until the start of rinsing) in which the most detergent solution is sprayed on the object to be cleaned after the operation of spraying the detergent solution a plurality of times is completed. In addition, it is more preferable in terms of improving the cleaning action.

Other features and advantages of the invention will become more apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

It is a schematic explanatory drawing which shows an example of the bathroom cleaning apparatus which concerns on this invention. (A) to (c) are time charts showing an operation example of the bathroom cleaning device shown in FIG. (A) and (b) are time charts showing the inverse proportion to the operation example of FIG.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The bathroom cleaning device A shown in FIG. 1 is configured as a bathtub cleaning device for cleaning the bathtub 1, and its basic hardware configuration itself is the same as that conventionally known.

Specifically, the bathroom cleaning device A is provided in the cleaning nozzle 2 attached to the bottom of the bathtub 1, the hot water flow path 3 connected to the cleaning nozzle 2, the hot water flow path 3, and to the cleaning nozzle 2. Hot water supply valve Va for switching the hot water supply on and off, the venturi section 30 provided in the middle of the hot water flow path 3, the detergent supply path 6 for supplying detergent from the detergent tank 5 to the venturi section 30. The detergent supply path 6 is provided with a detergent valve Vb for switching on / off of the detergent supply to the ventilator portion 30, and a control unit 7 for executing opening / closing control of the detergent valve Vb and the pouring valve Va. ing. The bathtub 1 (strictly speaking, the inner surface of the bathtub 1) is an example of a cleaning target in the present invention.

Hot water can be supplied to the hot water flow path 3 from a hot water supply device (not shown) or a hot water supply source such as a water pipe. A flow rate sensor Sa and a flow rate adjusting valve Vc are appropriately provided in the hot water flow path 3, and control of the valve opening degree of the flow rate adjusting valve Vc is executed based on the value detected by the flow rate sensor Sa. Although the details of the venturi portion 30 will be omitted, the venturi portion 30 is provided with a throttle portion in which a part of the internal flow path is partially throttled, and the hot water flows in the vicinity of the throttle portion 30 at high speed. Negative pressure is generated. Based on this negative pressure, the detergent smoothly flows from the detergent supply path 6 into the venturi section 30 and eventually into the hot water flow path 3, so that a detergent solution in which the detergent and hot water are mixed can be generated. The detergent is, for example, a liquid detergent, but a powder detergent or the like can also be used.

The pouring valve Va is, for example, a pilot type electromagnetic on-off valve. On the other hand, the detergent valve Vb is an electromagnetic on-off valve such as a direct acting type. The control unit 7 is configured by using, for example, a microcomputer, and is configured to control the pouring valve Va and the detergent valve Vb in a manner as described later. An operation unit 70 having various operation switches is connected to the control unit 7.

Next, an example of the operation control executed in the bathroom cleaning device A and the operation will be described.

In the bathroom cleaning device A, when a predetermined switch operation is performed in the operation unit 70, as shown in FIG. 2, a preliminary rinsing operation for a predetermined time Ta, a plurality of detergent liquid spraying operations for a predetermined time Tb, and a detergent solution spraying operation for a predetermined time Tb, and Rinsing (main rinsing) operations over a predetermined time Tc are sequentially executed.

Here, the preliminary rinsing operation is an operation for roughly cleaning the bathtub 1 by using hot water that does not contain detergent. Specifically, this preliminary rinsing operation is executed by opening only the pouring valve Va among the pouring valve Va and the detergent valve Vb, and ejecting hot water containing no detergent from the cleaning nozzle 2. ..

The detergent liquid spraying operation a plurality of times is an operation in which the detergent liquid is intermittently sprayed from the cleaning nozzle 2 to the bathtub 1, and the detergent liquid spraying operation each time is basically a pouring valve Va and a detergent. It is executed by opening both of the valves Vb for a suitable time Td. However, it is also possible to cause a difference in the opening / closing timing between the pouring valve Va and the detergent valve Vb.

The multiple detergent solution spraying operations are performed intermittently via a plurality of interval periods I (indicated as I1 to I5 in FIG. 2). However, these interval periods I1 to I5 are not constant, and they are configured to monotonically increase as the number of executions of the detergent solution spraying operation increases (as the interval period in the later order increases). The concept of monotonous increase is as described in the section of the outline of the invention.
In this embodiment, the relationship is I1 <I2 = I3 <I4 <I5. Further, when the interval periods I1 to I5 are viewed from different aspects, the respective lengths from the first interval period I1 to a predetermined order (for example, the third interval period I3) are the interval periods I4 thereafter. , I5 is shorter than the respective lengths.

Preferably, the length of the interval period I1 to I5 described above and the length of the additional interval period I6 described later are determined by the control unit 7 depending on the temperature of the detergent solution, the room temperature of the bathroom, or the amount of the detergent solution sprayed. It is configured to be changed by control. Further, it can be changed as appropriate by the user operating the operation unit 70.

After the plurality of detergent liquid spraying operations described above are completed, a rinse (main rinse) operation is performed after an additional interval period I6 is set. Preferably, the additional interval period I6 has a length equal to or greater than the longest interval period I5 among the above-mentioned interval periods I1 to I5, and more preferably a length longer than the interval period I5. The rinsing operation is an operation of spraying hot water to the bathtub 1 by opening the pouring valve Va while keeping the detergent valve Vb closed, as in the preliminary rinsing operation described above. By this rinsing operation, the detergent solution and dirt are washed away from the bathtub 1.

In the above-mentioned multiple detergent liquid spraying operations, since the detergent liquid is repeatedly sprayed to the bathtub 1 at short intervals at the initial stage, it is possible to spray a large amount of the detergent liquid to the bathtub 1 in a short time. .. On the other hand, when a large amount of detergent solution is sprayed on the bathtub 1, the interval is long, so that many detergent solutions can be effectively applied to stains such as sebum. As a result, it is possible to obtain an excellent cleaning action while preventing the entire processing time of the plurality of detergent liquid spraying operations from becoming too long. Further, since the additional interval period I6 is longer than each of the interval periods I1 to I5, it becomes more preferable in order to improve the cleaning action.

FIG. 3 shows the inverse proportion to the present embodiment. In this inverse proportion, the lengths of the plurality of interval periods I1 to I5 and the additional interval period I6 are constant. Comparing the areas (vertical line pattern portions) of the areas surrounded by the graphs of the cumulative spraying amount of the detergent solution shown in FIGS. 2 (c) and 3 (b), the present embodiment of FIG. 2 (c) is compared. The area is larger than that in the inverse proportion of FIG. 3 (b). According to this embodiment, an excellent cleaning action can be obtained even when compared with the inverse proportion of FIG.

The present invention is not limited to the contents of the above-described embodiments. The specific configuration of each part of the bathroom cleaning device according to the present invention can be variously redesigned within the scope of the present invention.

In the present invention, the plurality of interval periods set during the plurality of detergent liquid spraying operations are monotonically increased, or the length of each interval period from the beginning to a predetermined order is set to the length of each interval period thereafter. The configuration is preferably shorter than the length, but is not limited to this. Of the plurality of interval periods, at least one interval period may be longer than the other interval period in the earlier period.
The detergent liquid spraying operation is performed intermittently over a plurality of times, but the specific number of times is not limited. The number of executions of the detergent liquid spraying operation can be changed by operating an operation switch or the like.

The cleaning nozzle may be provided so that the detergent solution can be sprayed, and the specific configuration and number thereof are not limited. As the pouring valve and the detergent valve, valves of other types other than the solenoid valve can also be used. The type of detergent does not matter.
The cleaning target is not limited to the bathtub, and other than this, for example, the floor surface, the side wall surface, the ceiling, the bathtub lid, and the like of the bathroom can be used.
