Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plumbing appliance such as an alkaline ionized water generator having a fluid passage for water or the like and electric components such as a control section in a housing made of synthetic resin.

[0002]

2. Description of the Related Art In a plumbing appliance such as an alkaline ionized water generator having a water flow section and a control section in the same housing, if water leaks from the water flow section and the control section is immersed, a short circuit may occur and malfunction may occur. It is common to provide a water draining means for discharging the leaked water to the outside at the bottom of the housing because it has an adverse effect such as a fire. For example, as shown in FIGS. A slit 51 is provided, and FIGS.
As shown in FIG. 2, a mesh 53 is formed in the opening 52 of the housing bottom 50.
Is pasted.

[0003]

However, in the former water draining means having the slit 51 structure, there is a problem that cockroaches enter the inside of the housing through the slit 51 although the water discharging ability is high. In particular, in the case of appliances used in the kitchen, it is a problem to prevent cockroaches from entering, but the larvae of cockroaches have a head size of about 1.5 mm, and in consideration of the characteristics that can flatten the body, For example, even if the short direction is 1 mm or less, a slit 51 having a long direction of 1 mm or more penetrates, and it is extremely difficult to form a slit 51 having a narrow width.

In order to prevent the cockroach larvae from entering, a mesh 5 is inserted into the opening 52 of the housing bottom 50 as shown in FIG.
However, since the opening 52 is provided in a part of the housing, the strength of the housing is weakened, and the attachment of the mesh 53 or the insert molding of the mesh 53 increases the manufacturing cost. Become.

Therefore, in order to prevent moldability and to prevent cockroach larvae from penetrating, it is conceivable to use a water draining means with a narrow pore. However, as shown in FIG. The water film 55 is stretched by the tension, and the surface tension overcomes the capillary phenomenon passing through the pores, so that the water droplet does not swell, and the water inside cannot be discharged to the outside.

According to the present invention, in a plumbing appliance such as an alkaline ionized water generator, the moldability of a synthetic resin casing is not impaired, and in particular, cockroaches can be completely prevented from entering and the strength of the casing is not deteriorated. It is an object of the present invention to provide an inexpensive drainage means in a housing.

[0007]

In order to solve the above-mentioned problems, the present invention has a fluid passage and an electric component in a synthetic resin casing, and leaks water from the fluid passage to the outside of the casing. What is claimed is: 1. A hydroelectric appliance device comprising a drain device for discharging water provided at a lower portion of a housing, wherein said water drain device has a small diameter portion having a diameter of 0.5 to 1.5.
It is characterized in that it comprises a plurality of drain holes in a tapered shape in which the lower opening expands in mm, and the opening ends of adjacent openings overlap or are in close contact with each other.

In this manner, the water accumulated in the housing passes through the small diameter portion of the pore by capillary action, spreads along the tapered shape of the opening, and drops from the adjacent drain hole outlet. Combine with The combined water drops gradually swell and drop when their own weight exceeds the surface tension, and are discharged without stagnation.

Of course, the diameter of the small diameter portion of the drain hole is 0.5 to
Since it is about 1.5 mm, invasion of cockroach larvae can be prevented, and the thickness of a pin for forming a pore when forming a housing can be secured to 0.5 to 1.5 mm, so that moldability is not impaired. In addition, the strength of the housing can be maintained.

FIGS. 1 to 3 show a first embodiment of the present invention.
Alkaline ionized water generator 5 as a plumbing appliance
Is a control unit 6 as an electric component, a water amount sensor 7, a hollow fiber membrane 7 as a water purifier, an activated carbon 8, a temperature actuated valve 9,
Fluid passage 12 connecting electrolytic cell 10 and valve unit 11
Is provided in the housing 13. The water that has entered through the water amount sensor 7 is purified by the hollow fiber membrane 7 and the activated carbon 8, separated into alkaline water and acidic water in the electrolytic cell 10, and supplied through the valve unit 11. The control unit 6 adjusts the current to the electrolytic cell and controls the current of the heater 14 for heating and regenerating the activated carbon. The casing bottom 1 of the casing 13 is provided with a large number of drain holes 2 for discharging water leaked from the water passage section to the outside.

The drain hole 2 formed in the housing bottom 1 of the resin housing 13 is formed by a circular small diameter portion 3 and a tapered opening 4. Since the small diameter portion 3 has a diameter of 1 mm,
The cockroach larva cannot enter the inside of the housing 13 through the drain hole 2. If the small-diameter portion 3 has a diameter of 0.5 mm to 1.5 mm, cockroach larvae cannot enter the inside of the housing 13 through the drain hole 2. In addition, the shape of the opening 4 on the side from which water is discharged is widened in a tapered shape, and adjacent tapered outlets of the same shape are in close contact with each other.

Referring to FIG. 4, a state in which water is drained will be described. As shown in FIG. 4A, the water 15 accumulated inside the casing 13 passes through the small-diameter portion 3 by capillary action, spreads along a tapered shape near the outlet, and forms water droplets 16 from the adjacent drain hole 2. Join. Furthermore, the combined water droplets 16 are shown in FIG.
As shown in (b), since its own weight exceeds the surface tension and falls without stagnation, smooth drainage becomes possible.

Further, since the water drain hole 2 of the present shape is formed by injection molding as a part of the resin housing 13, a step of attaching a mesh or inserting a wire as in the conventional example is unnecessary. Further, since a sufficient pressure portion is secured between the adjacent drain holes 2, there is no deterioration in strength. Since the drain holes 2 of the present invention exhibit an effect when they are adjacent to each other, they need to be used as a drain hole group as shown in FIG. 2 in an actual layout. The number of holes in the drainage hole group is set according to the estimated drainage amount.

FIGS. 5 and 6 show a second embodiment of the present invention.
The openings 4 of the drain holes 2 are provided adjacent to each other so as to partially overlap. The basic configuration is the same as that of the first embodiment, but since the openings are partially overlapped, the area occupied by all the drain holes can be reduced as compared with the first embodiment. .

FIGS. 7 and 8 show a third embodiment of the present invention.
The drain holes 16 are adjacent to each other in a truncated cone shape. An upper small diameter portion 17 and a tapered opening 18 are formed. Since the small-diameter portion 17 has a diameter of 1 mm, the cockroach larva cannot enter the inside of the housing 13 through the drain hole 16. Further, the shape of the opening 18 on the side for discharging water is widened in a tapered shape, and the adjacent tapered outlets of the same shape are in close contact with each other. The state in which water is drained is the same as that of the first embodiment. However, since the shape is simpler than that of the first embodiment, the manufacture is easy. Since it is thinner than the embodiment, it is not preferable to have the strength of the housing.

[0017]

According to the present invention, there is provided a water supply and drainage device in which a fluid passage and an electric component are provided in the same casing, and a drain hole for discharging water leaking from the fluid passage to the outside of the casing is provided at the bottom of the casing. An appliance, wherein the shape of the drain hole is circular and the minimum diameter of the hole is 0.
5 to 1.0 mm, and the hole outlet on the side where the housing is in contact with the outside has a slope shape, and the slopes of the adjacent drain holes are in close contact or close to each other. Even in the case of occurrence, even if the drain hole provided for the plumbing appliance which does not cause malfunction is a small opening through which cockroaches do not enter, water can be drained smoothly.
