Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a sanitary cleaning device with a private part cleaning function, and in particular, the invention relates to a sanitary cleaning device that has a private part cleaning function, and in particular, it converts the cleaning water into foam. The present invention relates to a nozzle device capable of ejecting water.

0002

[Conventional technology]

A sanitary cleaning device with a local cleaning function uses heated cleaning water through a nozzle device. A structure in which the liquid is injected toward a local area is common, and an example of this is shown in FIG.

0003 In the figure, a casing 1 of a sanitary cleaning device is fixed to a toilet main body 50. A toilet seat 60 and a toilet lid 61 are attached to the sink 1 so as to be openable and closable. Casing 1 Inside, there is a tank that heats the washing water, a hot air fan for drying, and a control unit. Each function is operated using the operating section 1a provided on the top surface of the casing 1. Ru. Then, a nozzle body 51 for private part cleaning is installed so as to be freely retractable from inside the casing 1. After moving it to the cleaning position, it is cleaned from the jet hole of the nozzle head at the tip. Spray water.

0004 The nozzle head at the tip of the nozzle body 51 is a hollow body, and has a plurality of jets on its upper surface. This is a hole that has been opened. This jet hole allows water to be sprayed even when the amount of cleaning water supplied is low. In order to prevent the force from becoming too weak, the aperture diameter is relatively small. For this reason, When the amount of washing water is increased, the force of the jet water hitting the private parts becomes considerably stronger, Pain is often felt.

[0005] In order to prevent such pain, for example, Japanese Patent Application Laid-Open No. 57-18072 As described in Publication No. 7, the water jetted from the nozzle head is turned into foam. is proposed. This is done by mixing air bubbles into the washing water. Even if the force of the cleaning water is strong, the foam can provide soft-touch cleaning. It is. The structure for turning the washing water into foam can be widely used in conventional foam faucets, etc. As in the case of This involves opening an air hole on the downstream side to suck in air from the outside. like this With this structure, the internal pressure decreases due to the increased flow speed after the water passes through the holes in the pressure reducing plate. , outside air is sucked in through the air holes and mixed into the water, resulting in foamy flow. be done.

[0006]

[Problem that the idea aims to solve]

However, in order to promote the mixing of air into the water, a fine mesh filter is used. Since it is built into the flow path, limescale etc. tend to adhere to this filter. For this reason, the flow ducts may become obstructed, which may affect proper flow rate injection. Also , since parts with high flow resistance such as pressure reducing plates and filters are incorporated, cleaning is difficult. Injection pressure cannot be secured unless the water flow rate is increased. Therefore, the lower limit of the minimum flow rate is higher than with a normal nozzle device, and even if it turns into foam, the force of the cleaning water is As the pain becomes stronger, the cause of the pain cannot be completely eliminated. Furthermore, pressure reducing plates, filters, etc. Assembly work can be complicated as multiple parts are assembled into a small nozzle head. stomach.

[0007] The problem to be solved with this invention is to allow cleaning water to flow without clogging the flow path. The purpose is to make it possible to form foam with a simple structure.

[0008]

[Means to solve the problem]

This invention has a cleaning water jet hole in the nozzle head of the nozzle body, and the cleaning water jet hole A nozzle device in which a cleaning water flow path is formed up to the end of the cleaning water flow path, A foaming chamber is provided, the foaming chamber being sized to include a cleaning water spout; a small hole that communicates the inside of the nozzle head with the washing water flow path, and an opening on the outside of the nozzle head. and an air suction path which is formed by extending the air suction path to the vicinity of the hole. It is characterized by:

[0009]

[Effect] The cleaning water sent from the cleaning water flow path enters the foaming chamber through the holes. When flushing, the flow of cleaning water is accelerated due to the small size of the holes. On the other hand, the air suction path Since it extends to the vicinity of the hole, the ejection is prevented by increasing the flow of cleaning water around the hole. subject to the ta effect. Therefore, air flows from outside the nozzle head through the air suction path. is drawn into the foaming chamber, mixes with the wash water, and foams.

0010 In this way, the internal flow path of the nozzle head can be maintained without using a pressure reducing plate or filter. Just by narrowing down once to increase the flow velocity and placing the air suction path in this high flow velocity area, foam can be removed. It becomes possible to

[0011]

【Example】

Figure 1 is a longitudinal sectional view showing the nozzle head part of the nozzle device of the present invention, and Figure 2 is the nozzle. FIG. 3 is a plan view showing an ejection hole formed in the head.

0012 The nozzle device is installed in a casing 1 fixed to the toilet body as shown in the conventional example in Fig. 5. The right side view is shown in Fig. 3.

[0013] In the figure, a base 2 of a nozzle device is fixed inside a casing 1. A nozzle body 3 is incorporated into the base 2 so as to be movable in its axial direction. base 2 forms a concave curved sliding surface 2a that receives the lower surface of the pipe-shaped nozzle body 3. The tip has a cleaning pad for cleaning the nozzle head 4 of the nozzle body 3. A chamber 2b is provided. Further, a drive motor 5 is fixed to the base end side of the base 2. A drive pulley 5a is provided on its output shaft. Then, on this drive pulley 5a The timing belt 6 is wound around the two pulleys 5b, 5c and 5c provided on the base 2. This timing belt 6 is looped around the tension pulley 5d.

[0014] FIG. 4 is a schematic diagram showing the cleaning water supply system to the nozzle body 3, including the on-off valve and the flow rate. It includes a valve unit 1b having a regulating valve function, a hot water tank 1c, and a control section 1d, A flow rate adjustment switching unit 1e is installed between the hot water tank 1c and the nozzle body 3. I'm here. Then, drive the nozzle body 3, set the cleaning position, and adjust the hot water tank 1c. Setting the hot water temperature, etc., and operating the valve unit 1b and flow rate adjustment switching unit 1e , is performed using the operating section 1a provided in the casing 1, as in the case of FIG.

[0015] Inside the nozzle body 3, two separate channels 3a and 3b are formed as shown in Fig. 1. Two lines are supplied from the flow rate adjustment switching unit 1e to each of the flow paths 3a and 3b. Connect the pipes 7a and 7b. A timing mark is provided on the circumferential surface of the base end of the nozzle body 3. A clamp 3c is provided to grip the belt 6, and as the timing belt 6 runs, the nozzle Move body 3. In addition, in order to follow the movement of this nozzle body 3, the supply pipe 7 A and 7b are flexible.

[0016] The nozzle head 4 has an internal flow that communicates with the flow paths 3a and 3b of the nozzle body 3, respectively. The channel 4a and 4b are formed, and the upper surface of one of the internal flow channels 4b is equipped with a jet for cleaning the anus. Exit hole 4c is opened. Three jet holes 4c are arranged as shown in FIG. 2(a). This is what I did.

[0017] A foaming chamber 8 for foaming the supplied water is provided at the end of the other internal flow path 4a. . This foaming chamber 8 is partitioned from the internal flow path 4a by a partition wall 8a, and It communicates with the internal channel 4a through a hole 8b formed in the partition wall 8a. This hole 8b is a bubble The flow rate of the water into the atomization chamber 8 can be increased. It has a small inner diameter, and an annular wall 8c is coaxially raised around the hole 8b. ing.

[0018] On top of the foaming chamber 8, a separate member from the nozzle head 4 is integrated. A foam head 9 is provided. This foam head 9 has four washers as shown in Fig. 2(b). The clean water jet holes 9a are arranged concentrically, and an air intake is provided in the center of these clean water jet holes 9a. A pull block 9b is provided. The air suction block 9b is coaxial with the hole 8b of the partition wall 8a. It is located at the top, has an air suction passage 9c inside, and has disc-shaped wings 9d on the outer periphery. is forming. The air suction path 9c closes the end face facing the hole 8b of the partition wall 8a and extends toward the outer periphery. It is assumed to be bifurcated in the direction, and water enters the air suction path 9c directly from the hole 8a. Make it difficult.

[0019] In the above configuration, when cleaning the anus, operate the switch on the operating section 1a. As a result, the drive motor 5 is operated and cleaning water is supplied only to the supply pipe 7b. this As a result, the nozzle body 3 advances and its nozzle head 4 is set to the cleaning position. At this time, cleaning water is sprayed from the spout hole 4c. In this case, since air is not mixed in, , cleaning is performed using normal cleaning water that does not foam.

[0020] On the other hand, the stroke of the nozzle body 3 is lengthened to supply cleaning water only from the supply pipe 7a. The cleaning water then flows into the foaming chamber 8 from the internal channel 4a. At this time, the hole Since the opening diameter of 8b is small, the flow rate of the cleaning water immediately after flowing into the foaming chamber 8 becomes faster, and at the same time the pressure around the lower end of the air suction block 9b decreases, the air An ejector effect is applied to the suction path 9c. For this reason, the air suction path 9c Air is drawn into the foaming chamber 8 and mixed into the wash water. did Therefore, the cleaning water becomes foamy water containing air bubbles, and the cleaning water jetting hole 9 of the nozzle head 4 becomes foamy water. It is injected from a.

[0021] When the washing water is turned into foam, the annular wall 8c raised around the hole 8a is The high-velocity flow flowing from the hole 8b is made turbulent. As a result, the air suction path 9 Air from c is easily mixed into the turbulent washing water, promoting foaming. be done. In addition, the wings 9d provided around the air suction block 9b remove the foam that has been washed away. The purified water bends the flow path toward the cleaning water jet hole 9a to provide resistance and at the same time to reduce the flow path area. Tighten temporarily. As a result, the foam becomes compressed and the washing water flows, removing the foam. After being made into fine particles, it is discharged from the cleaning water jetting hole 9a.

[0022] In this way, the cleaning water flows from the internal channel 4a into the foaming chamber 8 through the hole 8b. Only when the flow path shrinks and provides resistance, the speed of the flow increases and the air suction path 9c It is possible to draw in air from both sides. For this reason, as shown in the conventional example, pressure reducing plates and Compared to the case where a filter is installed, the flow path is easily closed due to the adhesion of water scale, etc. You will no longer be affected by this. Therefore, it is not necessary to increase the cleaning water supply pressure. Also, since foamy water is sprayed from the cleaning water spout 9a, cleaning with a soft touch is possible. Becomes Noh.

[0023] In addition, since the air suction hole 9c is opened on the top surface of the nozzle head 4, cleaning water is ejected. It is easily cleaned by water from the hole 9a. For this, for example using Even if dirt, etc. adheres to the air suction hole 9c during cleaning or when cleaning starts or ends, Since the supply pressure of the cleaning water is low, the cleaning water drips down the top surface of the nozzle head 4. This will remove any dirt that may have adhered to it.

[0024]

[Effect of the idea]

In this invention, a foaming chamber is provided in the nozzle head, and the cleaning fluid flowing into the foaming chamber is provided in the nozzle head. The flow rate of purified water is increased and the resulting ejector effect is used to empty the air suction passage. It can draw in air and turn the cleaning water into foam. Therefore, as in the conventional example, There is no need to incorporate multiple parts such as pressure plates and filters inside the nozzle head, and the The number of items and assembly man-hours can be reduced. In addition, a fine net-like material is added to the internal flow path. Since it is not incorporated, there is less adhesion of limescale, etc., and cleaning can always be performed with appropriate water pressure. becomes.
