Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water dispenser box designed for use in cold regions, particularly for general household use.

A water meter box accommodates a water meter and a water stop valve together with a part of its piping, and is buried underground with the top lid flush with the ground surface. As shown in the cross-sectional view, rectangular frame bodies 1 made of hard synthetic resin or the like and having upper and lower sides open are stacked in multiple stages (an example of two stages is shown in Fig. 1) depending on the depth of the buried location. It is formed into a single box body with a peripheral wall and a bottom plate 2, a lid plate 3, and an inner lid 4 arranged thereon.

Generally, in cold regions, to protect water meters from cold air, they are buried in the ground at a depth necessary to accommodate the cold weather in the region and kept at a relatively constant temperature.For example, in the Hakodate region of Hokkaido, In the Kitami region, the square frames mentioned above are buried in multiple tiers at a depth of 50 cm, and approximately 130 cm in the Kitami region. In this case, in cold regions, the area near the stratum surface freezes and swells during the winter, and the engaging portion between the rectangular frame at the depth at which the swell occurs, the so-called frost heaving depth, and the rectangular frame directly below it. There is a danger that the water meter may become frozen if it comes off, and the rectangular frame-shaped body buried underground is often destroyed by heavy pressure from above or earth pressure, which is especially noticeable in areas with heavy traffic. For this reason, in the above-mentioned rectangular frame, the lid is made of cast iron, etc., and the area near the ground surface of the rectangular frame is also reinforced with cast iron, etc., but it is still not sufficient and the lid is reinforced periodically (every 8 years). Even when the water meter was not being replaced, the water meter box had to be repaired and replaced.

This invention is particularly useful for water dispenser boxes for general household use, which can be buried deep underground to prevent the water dispenser box from coming off or being destroyed, and to efficiently maintain a constant temperature of the water dispenser and water stop valve. The bottom part, which houses the water meter and water stop valve, is of a specified size that does not interfere with plumbing work, etc., and the part from above to the top cover is an integral cylindrical body. The size shall be the minimum size that does not cause any problem in reading the meter of a water meter or operating a water stop valve. In other words, even in cold regions, the temperature underground is relatively warm, and the temperature near the ground surface changes drastically depending on changes in temperature, so the relatively warm air underground is stored in the water meter box. It is only necessary to maintain heat retention by suppressing the inflow of cold air from the upper part as much as possible, and for this reason, in this invention, the bottom part, which is the storage part, is made considerably wide so that a large amount of warm air can be stored, and The cross-sectional area of the cylindrical body serving as a passage for cooling air is narrowed to reduce the surface area cooled from the outside and to prevent the upper surface of the stored air from being completely cooled.

An embodiment of the present invention will be described based on FIG. 2a (perspective view) and FIG. 2b (side sectional view). Reference numeral 5 denotes a base box portion in which a water pipe 7 led from a piping hole 6, a water meter 8, and a water stop valve 9 are housed and attached. In this example, the size of the base box is approximately 42cm.
(Length) x 27cm (Width) x 25cm (Height) We assumed a water pipe for general household use with a diameter of 13 to 20mm. The base box part 5 is erected by locking and fitting a rectangular frame-shaped peripheral wall 11 on the upper surface of a bottom plate 10, and a top plate 12 is attached to the upper edge of the peripheral wall 11.
are fitted together to form a single shallow box, and as mentioned above, it has enough space to accommodate the water meter and water stop valve piping. This base box part 5 is normally made of reinforced plastic, but since it is buried deep underground, it may be made of normal hard synthetic resin in terms of strength.

Next, reference numeral 13 denotes a cylindrical body part, the lower end of which is fitted into a short cylindrical mounting part 14 of a required height provided near the center of the top plate 12 of the base box part 5, so as to be erected vertically.
As mentioned above, this cylindrical body part 13 has a cross-sectional size of 300 cm ² (in the case of a circular shape, the diameter is approximately 20 cm
cm) is sufficient. The cylindrical body portion 13 is made of a single piece of reinforced plastic, and may be either square or cylindrical in shape, but the cylindrical shape is superior in terms of strength against earth pressure and the like. Note that the short cylindrical attachment portion 14 may be provided with ribs 15 for reinforcement in part or all of it.

A lid 16 is fitted onto the upper surface of the cylindrical body portion 13 . It is preferable that the upper surface of this lid body is formed into an arcuate convex surface in order to increase the strength and to better seal the lid body with the cylindrical body portion. If the lid is flat or concave, if a large load is applied to it, the lid will bend, creating a gap between the lid and the cylindrical body, or causing damage to the cylindrical body. It may also fall inside. As for the material of the lid, there is no need to use cast iron or the like as in the past, and light-resistant reinforced plastic or the like is sufficient, and there is no need to particularly reinforce the area near the ground surface of the cylindrical body.

The water dispensing box of the present invention has a heat retention effect because the convection of cold air is considerably prevented without using an inner lid as in the conventional case. It will be more effective if the inner lid 17 for heat insulation is placed in a locked position.

Figures 3a and 3b are perspective and side sectional views of another preferred embodiment of the invention. Short cylindrical mounting part 1
2a and b that the cylindrical body part 13 is fitted on the outside of the cylindrical part 4, that there are no ribs, and that the inner lid 17 is placed on the short cylindrical mounting part. It is different from the example, and has a short cylindrical attachment part 14 and a cylindrical body part 1.
This is preferable because there is no risk of dirt or the like getting into the space between it and 3, and because it has a simpler structure and is easier to manufacture.

With the above-described configuration, the present invention allows the inside of the base box portion 5 to be kept warm at all times as described above, and the integrated cylindrical portion 1
The base end of 3 fits inside or outside the short cylindrical mounting part 14, and the outer periphery is flat up to the frost heave depth, so even if frost heave occurs on the ground, the water meter box will remain in the installed position. to prevent freezing. Since the cylindrical body part is smaller than the base box part, and the overall shape is correspondingly smaller, it is economical because less material is needed for the mold and water meter box than conventional ones. Particularly those with a circular cylindrical body can withstand direct and indirect pressure such as heavy pressure from above from cars and other heavy objects, lateral pressure such as earth pressure, and can be used semi-permanently. It has many advantages such as ease of manufacture.
