Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine such as a dishwasher and a human body local washing machine.

2. Description of the Related Art Conventionally, this type of cleaning apparatus has a structure as shown in FIGS. 5 and 6, for example, as disclosed in Japanese Patent Application Laid-Open No. 58-110731.

That is, the washing nozzle 2 is attached to the tip of the washing machine 1,
The nozzle cylinder 3 which comes in and out by water pressure is mounted. The washing nozzle 2 has a supply nozzle 4 forming a jet, a fountain port 5 expanding in a tapered shape, and one end opening at or near the tapered walls 6, 7 of the fountain port 5,
It has a pair of return paths 8 and 9 having the other ends opened at the bases of the tapered walls 6 and 7 on the side different from the opening 5 so that the jetted water alternately adheres and oscillates to the tapered walls 6 and 7. Has become.

Problems to be Solved by the Invention However, in the above-described configuration, efficient cleaning can be performed over a wide area, but for locally strong dirt, the jet flow spreads more than necessary, and the cleaning time becomes longer, There were problems such as an increase in the amount of washing water used.

The present invention solves such a conventional problem, and changes the shape of a cleaning jet according to the state of dirt to improve the cleaning efficiency and improve the cleaning sensation when used for human body local cleaning. It is the purpose.

Means for Solving the Problems In order to solve the above problems, the cleaning device of the present invention is a cleaning water supply means, a gas supply means, a cleaning nozzle which becomes a straight jet when liquid is ejected, and becomes an oscillating jet when ejecting a gas multiphase fluid. And a control means of the supply means.

Action The present invention has the above-described configuration, and when cleaning water made of liquid is supplied to a cleaning nozzle from cleaning water supply means,
The cleaning water becomes a straight jet and hits the surface to be cleaned and performs concentrated cleaning in a small area. Next, when air is added to the liquid washing water supplied from the washing water supply means by the gas supply means and the two-phase gaseous washing water is supplied to the washing nozzle, the washing water becomes an oscillating jet due to air bubble adhesion. The cleaning is performed on the surface to be cleaned and spread over a wide area.

Embodiment An embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 10 denotes a sanitary washing device, which is a washing device, comprising a main body 11, a toilet seat 12, and a toilet lid 13 in which functional elements are provided. Reference numeral 14 denotes an operation unit provided on the main body 11, reference numeral 14 denotes a toilet bowl, and the sanitary washing device 10 is fixed to an upper portion by bolts or the like. Numeral 15 denotes a low tank, which stores water for drainage.

In FIG. 2, reference numeral 16 denotes a pump indicating a cleaning water supply means.
17 is a hot water tank for washing water heating. Reference numeral 18 denotes a switching valve for selectively supplying cleaning water to the anal cleaning nozzle 19 and the bidet cleaning nozzle 20. Reference numeral 21 denotes a diaphragm pump indicating gas supply means, and check valves 22 and 23 are inserted into the inflow side and the outflow side, respectively. An outflow passage 24 of the diaphragm pump 21 is connected to a connection pipe 26 provided in a washing water supply flow passage 25 from an outlet of the heating tank 17.
Is in communication with 27 is a diaphragm pump drive motor. 28 is a blower for drying, a drive motor 29, a blower blade 30,
And a case 31. The blowing path 32 of the blower 28
Inside, a drying heater 33 is provided. Reference numeral 34 denotes a deodorizing blower, which includes a drive motor 35, a blower blade 36, and a case 37. Inside the output path 38 of the blower 34, a cross-flow type heat exchanger 39, an odor adsorbent 40, an adsorbent activation heater 41, an odor decomposition photocatalyst 42, and an ultraviolet lamp 43 are provided. A control unit 44 controls the operation of the pump 16, the hot water tank 17, the diaphragm pump 21, the switching valve 18, the drying blower 28, the deodorizing blower 34, and the like.

3 and 4 show the structure and operation of the cleaning nozzle 19,
The flow path has a two-dimensional configuration. In the figure, 45 is a supply port for forming a jet, 46 and 47 are left and right attachment walls located downstream of the supply port, and 48 is an ejection port formed at the downstream end of the attachment wall. F _A is the non-stick straight jets, F _B represents a wall attachment oscillating flow.

In the above-described configuration, in the case where the dirt is severe in the anal cleaning or it is desired to wash off with a strong cleaning feeling, the direct current jet operation instruction is issued by the operation unit 14. In response to this instruction, the forcing means 44 is operated, the pump 16 as the washing water supply means is started, and the diaphragm pump 21 is stopped. The washing water passes through the hot water tank 17, is sent to the anal washing nozzle 19 based on the setting of the switching valve 18, and is jetted toward the part to be washed. In this case, if during the jet from the supply port 45 contains no bubbles, jet by injection force of the cleaning water becomes a cleaning jet showing a straightness such as Fig. 3 F _A, washing narrow area The strength is strong in the range.

Next, in the case of relatively light stains or a wide range of stains in the anal cleaning, the operation unit 14 gives an instruction to operate the bubble-mixed oscillation jet. In response to this instruction, the control means 44 is activated, and the pump 16 which is the cleaning water supply means and the diaphragm pump 21 which is the gas supply means for mixing bubbles into the cleaning water are started to be in an operating state, and the bubbles are mixed into the cleaning water. I do. Then, the washing water passes through the hot water tank 17 in the same manner as described above, is sent to the anal washing nozzle 19 based on the setting of the switching valve 18, and is jetted toward the portion to be washed. At this time, since the washing water is jetted from the supply port 45 as a mixed phase jet containing air, the mixed phase flow causes the washing water containing bubbles to flow downstream due to the interaction between the mixed bubbles and the adhesion walls 46 and 47. As the flow rate decreases, the cross-sectional area increases and adheres to or adheres to the adhering wall,
Washing water becomes Fig. 4 F bubble laden oscillating jets such as _B performs vibrationally washed Upon cleaned surface. As a result, the cleaning has a soft feeling over a large area.

Effects of the Invention As described above, according to the cleaning device of the present invention, the following effects can be obtained.

(1) The cleaning efficiency can be improved by selecting the jet shape according to the degree of the dirt and the content of the dirt, such as straight jet cleaning for severe dirt, and cleaning for light dirt or widespread dirt, for example, when the dirt is widespread. .

(2) Since the bubble jet has a soft feeling of washing, the washing can be performed comfortably and with peace of mind even when the human body is washed, especially after surgery, when there is a local pain.

(3) Since switching between the straight jet flow and the bubble oscillation jet does not require a movable portion such as a control valve, the reliability can be improved and the cost can be reduced.
