Description

  The present invention relates to a bathroom cleaning apparatus.

There exist a thing of patent documents 1, 2 as a specific example of a bathroom cleaning apparatus.
In the bathroom cleaning apparatus described in these documents, for example, a cleaning nozzle is attached to the bottom of the bathtub, and a detergent solution can be sprayed from the cleaning nozzle to the inner surface of the bathtub. As an aspect at the time of spraying the detergent liquid on the inner surface of the bathtub, a plurality of times of the detergent liquid spraying operation are repeatedly performed repeatedly over a plurality of interval periods. If the detergent solution is sprayed in such a manner, the detergent solution can be permeated into dirt such as sebum on the inner surface of the bathtub during each interval period to enhance the effect of disassembling and removing the dirt.

  However, the prior art still has room for improvement as described below.

  In other words, in order to improve the cleaning action of the bathtub with the detergent liquid within a limited time, the detergent liquid is applied to the inner surface of the bathtub while shortening the period when the detergent liquid is not sprayed on the inner surface of the bathtub. It is desired to lengthen the period during which many are sprayed. However, in the prior art, the length of the interval period set during each detergent liquid spraying operation is fixed. Therefore, it is difficult to clean the bathtub in a manner in accordance with the above-described demand, and there is still room for improvement in obtaining an excellent cleaning action.

JP 2002-34812 A Japanese Patent No. 4822127

  The present invention has been conceived under the circumstances as described above, and an object thereof is to provide a bathroom cleaning apparatus capable of obtaining a cleaning ability superior to the conventional one.

  In order to solve the above problems, the present invention takes the following technical means.

  The bathroom cleaning apparatus provided by the present invention includes a cleaning nozzle capable of spraying detergent liquid toward a bathroom cleaning object, and a plurality of times of detergent liquid spraying operation by the cleaning nozzle has a plurality of interval periods. The bathroom cleaning device is capable of being repeatedly and intermittently executed, and at least one of the plurality of interval periods is more than one other interval period earlier than the interval period. It is characterized by being long.

  According to such a configuration, it is possible to shorten a period in which the cumulative amount of the detergent liquid sprayed on the object to be cleaned is short, and lengthen a period in which the cumulative amount of the detergent liquid is subsequently sprayed. Therefore, the cleaning effect by the detergent solution can be sufficiently exerted within a limited time, and a cleaning action superior to the conventional technique can be obtained.

  In the present invention, preferably, the length of each interval period from the beginning to a predetermined order among the plurality of interval periods 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 liquid sprayed on the object to be cleaned is shortened, and lengthen the period in which the cumulative amount of the detergent liquid is largely sprayed.

In the present invention, preferably, the length of each of the plurality of interval periods is configured to monotonously increase as the number of execution times of the detergent liquid spraying operation increases.
Here, the monotonic increase is a monotonic increase in a broad sense, and when the length of the interval period is a sequence of T _n , T ₁ ≦ T ₂ ≦ T ₃ ... It means a monotonous increase that is related, including 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.

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

  In the present invention, it is preferable that 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 spraying amount of the detergent solution, or a switch operation by the user.

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

  In the present invention, preferably, after the plurality of times of the detergent liquid spraying operation, the rinse water is sprayed from the cleaning nozzle to the object to be cleaned. The interval period from the end of the liquid spraying operation to the start of spraying of the rinsing hot water is longer than the longest interval period when the plurality of detergent liquid spraying operations are performed. .

  According to such a configuration, it is possible to lengthen a period (a period until rinsing is started) in which the detergent liquid spraying operation is completed a plurality of times and the most detergent liquid is sprayed on the object to be cleaned. In addition, it is more preferable for improving the cleaning action.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present 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)-(c) is a time chart which shows the operation example of the bathroom washing apparatus shown in FIG. (A), (b) is a time chart which shows the contrast with respect 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 apparatus A shown in FIG. 1 is configured as a bathtub cleaning apparatus for cleaning the bathtub 1, and the basic hardware configuration itself is the same as that conventionally known.

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

  Hot water can be supplied to the hot water channel 3 from a hot water supply source such as a hot water supply device or a water pipe (not shown). The hot water flow path 3 is appropriately provided with a flow rate sensor Sa and a flow rate adjustment valve Vc, and the valve opening degree of the flow rate adjustment valve Vc is controlled based on a detection value by the flow rate sensor Sa. Although the details of the venturi portion 30 are omitted, the venturi portion 30 includes a throttle portion that partially squeezes a part of the internal flow path, and the hot water flows through the throttle portion at a high speed in the vicinity thereof. 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 liquid 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 part 7 is comprised, for example using the microcomputer, and is comprised so that the pouring valve Va and the detergent valve | bulb Vb may be controlled by the aspect which is mentioned later. An operation unit 70 having various operation switches is connected to the control unit 7.

  Next, an example of operation control executed in the bathroom cleaning apparatus A and an operation thereof 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 over a predetermined time Ta, a plurality of detergent liquid spraying operations over a predetermined time Tb, and A rinsing (main rinsing) operation for a predetermined time Tc is sequentially executed.

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

  A plurality of times of the detergent liquid spraying operation is an operation in which the spray of the detergent liquid from the washing nozzle 2 to the bathtub 1 is intermittently performed, and each time of the detergent liquid spraying operation is basically the pouring valve Va and the detergent. This is performed by opening both valves Vb for an appropriate time Td. However, it is also possible to cause a deviation in the opening / closing timing of the pouring valve Va and the detergent valve Vb.

The plurality of detergent liquid spraying operations are intermittently executed through 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 increase monotonously as the number of executions of the detergent liquid spraying operation increases (as the interval period becomes later). The concept of monotonic increase is as described in the Summary of Invention section.
In this embodiment, I1 <I2 = I3 <I4 <I5. Further, when the interval periods I1 to I5 are viewed from different aspects, each of the lengths from the first interval period I1 to a predetermined order (for example, the third interval period I3) has a subsequent interval period I4. , I5 is made shorter than each length.

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

  After the above-described plurality of detergent liquid spraying operations are completed, a rinse (main rinse) operation is performed after an additional interval period I6 is set. Preferably, the additional interval period I6 is longer than the longest interval period I5 among the above-described interval periods I1 to I5, and more preferably longer than the interval period I5. The rinsing operation is an operation of spraying hot water on the bathtub 1 while 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 liquid and dirt are washed away from the bathtub 1.

  In the above-described multiple times of the detergent liquid spraying operation, the detergent liquid spraying to the bathtub 1 is repeated at a short interval in the initial stage. Therefore, a large amount of detergent liquid can be sprayed to the bathtub 1 in a short time. . On the other hand, since a long interval is taken at the stage where a lot of detergent liquid is sprayed on the bathtub 1, a lot of detergent liquid can effectively act on dirt such as sebum. As a result, it is possible to obtain an excellent cleaning action while preventing the overall 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 is more preferable for improving the cleaning action.

  FIG. 3 shows a comparison with the present embodiment. In this comparison, the lengths of the plurality of interval periods I1 to I5 and the additional interval period I6 are constant. Comparing the area (vertical line pattern portion) of the region surrounded by the graph of the cumulative spraying amount of the detergent liquid shown in each of FIG. 2C and FIG. 3B, the embodiment of FIG. However, the area is larger than the proportionality in FIG. According to the present embodiment, an excellent cleaning action can be obtained even when compared with the comparative example of FIG.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the bathroom cleaning apparatus according to the present invention can be varied in design in various ways within the intended scope of the present invention.

In the present invention, a plurality of interval periods set during a plurality of detergent liquid spraying operations are monotonously increased, or the length of each interval period from the beginning to a predetermined order is set for each subsequent interval period. Although it is preferable to make the configuration shorter than the length, the configuration is not limited to this. Of the plurality of interval periods, at least one interval period only needs to be longer than another interval period earlier than that.
The detergent liquid spraying operation is intermittently executed a plurality of times, but the specific number of times is not limited. It is also possible to adopt a configuration in which the number of execution times of the detergent liquid spraying operation can be changed by operating an operation switch.

The cleaning nozzle only needs to be provided so as to be able to spray the detergent solution, and its specific configuration and number are not limited. As the pouring valve and the detergent valve, other kinds of valves other than the electromagnetic valve can be used. Any type of detergent is acceptable.
The object to be cleaned is not limited to a bathtub, and other than this, for example, a floor surface of a bathroom, a side wall surface, a ceiling, a bathtub lid, and the like can be used.
