Description

  The present invention relates to a drainage device for a sink tub.

  In the case of a cascading bathtub in which hot water is supplied from the top of the bathtub using a sprue or the like and drained without filtering, drainage is conventionally performed by overflow from the top of the bathtub as shown in FIG. In this method, the relatively high-temperature hot water supplied from the upper part of the bathtub is not sufficiently mixed with the bathtub water and is discharged at a high temperature, so that the bathtub water is not sufficiently kept warm and at the same time waste heat energy contained in the drainage is wasted. Has also become.

  In order to solve the above-mentioned problem, there is a method of draining water from the bottom of a bathtub and setting up a drainage pipe in a torii shape for water level adjustment. In FIG. 10, the lower surface of the horizontal pulling pipe portion of the torii pipe has the same water level as the water level of the bathtub, and the drainage at the same water level as the bathtub is provided in the pipe on the bathtub side from the horizontal pulling pipe portion of the torii pipe. Is flowing. At this time, when the water level in the bathtub rises, the drainage is drained over the horizontal pipe portion of the torii pipe, which is the overflow surface. In this method, water can be drained from the lower part of the bathtub at a relatively low temperature, and the water level can be adjusted with a simple structure that does not use a sensor.However, if the pipe from the bathtub to the torii pipe is lengthened, accumulated water increases and sanitation increases. Since it is necessary to install near the bathtub, it is necessary to shorten the time required for the water flowing out of the drain port to drain through the horizontal piping section of the torii pipe. And the view of the bathhouse is spoiled.

  Therefore, an object of the present invention is to provide a drainer that can make the hot water temperature of a hanging bath tub uniform without deteriorating the landscape and keep the water level constant.

  In order to solve the above problems, a drainer according to the present invention includes a partition plate that divides an internal space into two chambers in an axial direction inside a columnar member having a hollow interior and a closed upper and lower bottom. A space is provided between them, and they are vertically adhered to the lower bottom, arranged so as to adhere to a certain side surface and the opposite surface, and contact the bottom surface with the side surface of one of the chambers separated by the partition plate. The low-temperature water outlet is disposed at the height, and the low-temperature water inlet is disposed at a height between the height in contact with the bottom surface and the height of the upper end of the partition plate on the side surface of the other chamber. . At the time of construction, the upper end of the partition plate is adjusted to the expected water level of the bathtub, the drain provided on the bottom of the bathtub and the low temperature water inlet of the present invention are connected by a communication pipe, and the low temperature water outlet is connected to the drain pipe. The cross-sectional shape of the column member for performing this function may be any shape such as a circle including an ellipse or a polygon.

  The upper end of the partition plate plays the same role as the lower surface of the horizontal drawing pipe part when draining using torii pipe. That is, drainage at the same level as the bathtub flows into the interior of the room having the low-temperature water inlet of the present invention, and when the water level in the bathtub rises, the drainage exceeds the upper end of the partition plate, which is the overflow surface, and the present invention Into the room where the low temperature water outlet is located and drained. Since the appearance of the present invention is a pillar, if the coating is applied according to the scenery, the function can be performed without impairing the scenery of the bathroom. In addition to the single color, the coating may be a mixture of colors, gradation, metallic, glitter, pearl, marble, pseudo wood, pseudo stone, and the like.

  To implement the present invention, it is necessary to adjust the height of the upper end of the partition plate to the water level of the bathtub. For this reason, if the height adjustment mechanism is provided in the present invention, construction on site becomes easy. The height adjustment mechanism is realized by stacking two cylinders having similar shapes in cross section, adjusting the height to an appropriate height, and holding the same. If the height adjusting mechanism is provided below an extended portion of the side surface of the present invention, that is, below the low-temperature water inlet, the low-temperature water outlet and the main body bottom, the height can be adjusted without impairing the function.

  If a sensor such as a water level gauge cannot be mounted on the bathtub because the mounting hole cannot be opened due to the influence of the material of the bathtub or the like, and it is not desired to design the mounting hole, the present invention can be mounted. In this case, it is installed in the room having the low-temperature water inlet of the present invention. The water level gauge may be an electrode rod type or a pressure sensing type. In addition, use of a thermometer or a water quality monitoring sensor is also conceivable.However, since water with a low flow velocity is not measured immediately after being discharged from the bathtub, for example, when measuring circulating water with a relatively high flow velocity in a machine room. It is less accurate in measuring the quality of bath water.

  By implementing the present invention, it is possible to provide a drainer that can make the hot water temperature of the hanging bath tub uniform without impairing the landscape and keep the water level constant.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 show a basic structure and a use state of the present invention, and FIGS. 6 to 8 show an applied embodiment.

  1 and 2 show a typical embodiment of the present invention. FIG. 1 is a front view of the present invention, and FIG. 2 is a full sectional view. The height of the low-temperature water inlet of reference numeral 112 may be in the range from the bottom of the main body to the upper end of the vertical partition plate of reference numeral 116, but is representatively described at the bottom. The upper end of the vertical partition plate is an overflow surface in the present invention, in other words, a height at which drainage starts, and is indicated by a partition plate overflow surface of reference numeral 233.

  A horizontal partition plate 115 is provided in the main body 111 of the present invention at a position where the lower end of the low-temperature water outlet 113 is aligned with the height. This is the bottom as the core of the present invention, and corresponds to the lower bottom of the hollow columnar member described in the paragraphs 0008 to 0008. The lower portion of the horizontal partition plate has a shape in which a side surface of the main body is extended and a protruding edge is provided, and this is a fixing portion for fixing to a foundation or the like. Inside the main body, there is a vertical partition plate 116 that separates the internal space. Hereinafter, of the partitioned internal space, the side having the low-temperature water inflow port denoted by reference numeral 112 is referred to as a drainage water level adjustment chamber denoted by reference numeral 231, and the side having the low-temperature water flow outlet port denoted by reference numeral 113 is referred to as a drainage outflow chamber denoted by reference numeral 232. In addition, in order to facilitate maintenance such as cleaning and inspection, a portion corresponding to the upper bottom of the present invention is opened, and a lid 114 is attached in a watertight manner.

  The maximum height at which the low-temperature water inlet of reference numeral 112 is attached ranges from the bottom of the main body to the upper end of the vertical partition plate of reference numeral 116, as described in paragraph 0012. This is because the upper end of the vertical partition plate is adjusted to the water level of the bathtub at the time of construction, and the height beyond that exceeds the limit of the height at which drainage flows without power.

  3 to 5 are views showing a use state of the present invention, FIG. 3 is a construction state, and FIGS. 4 to 5 are diagrams illustrating a mechanism of water level adjustment by enlarging an A portion. FIG. 3 illustrates a bathtub 310 and the present invention in cross-section for illustration. A flow control valve is provided in the piping between the bathtub and the present invention. In FIG. 3, it is represented by a manual flow control valve denoted by reference numeral 341. The flow control valve may be electrically operated. In addition, a drain pipe for completely draining the inside of the pipe including the inside of the present invention for cleaning or the like is provided, and a drain valve 331 is provided. The drain valve is normally closed. At the start of use, as shown in FIG. 4, the bathtub surface of reference numeral 212 and the water surface in the present invention of reference numeral 213 are in the same water level and are in a balanced state. Here, when replenishment of hot water is started from the hot water discharge port denoted by reference numeral 320, the water level of the drainage in the present invention connected by the communication pipe rises by the amount of the replenishing water, and exceeds the overflow surface of the partition plate denoted by reference numeral 233. It flows to the drainage outflow chamber denoted by reference numeral 232 and is drained.

  When the present invention is carried out, the water is drained from the bottom instead of the overflow from the top of the bathtub. In such a case, the flow control valve can be throttled to overflow from the edge of the bathtub. The opening is adjusted by looking at the ratio of the amount of overflow from the tub edge to the amount of waste water from the present invention. This can also be used to create overflowing bathtubs.

  FIG. 6 shows an embodiment with a height adjustment mechanism. In this figure, the height adjustment portion of reference numeral 128 is larger than the main body, and the main body is inserted into the height adjustment portion. On the contrary, the height adjustment portion is smaller and the main body is It can also be manufactured so as to cover the adjustment part. In this embodiment, if the height is adjusted and held so that the overflow surface of the partition plate 233 and the bathtub water level are matched at the time of construction at the installation site, fine water level adjustment is possible.

  FIG. 7 shows an embodiment with a sensor, particularly with an electrode type water level gauge. When the bathtub cannot be equipped with a water level gauge due to the fact that the material of the bathtub cannot withstand drilling and is fragile, or is too hard and the cost of drilling is too high. Used to control the filling valve when filling. The water level gauge indicated by reference numeral 138 is attached to the drainage water level adjustment chamber indicated by reference numeral 231. The size ratio of the two chambers does not have to be 1: 1 and depends on the amount of drainage. However, in order to reduce the size of the equipment, the side to which the water level gauge is attached, that is, the side of the drainage water level adjustment chamber becomes larger in comparison. . Further, other sensors, such as a thermometer, can be attached in place of the water level gauge, but this is not preferable because the accuracy is low as described in paragraph 0008.

  FIG. 8 shows a construction example in which an overflow effect of a hanging bathtub is added. A human sensor and a control panel are added to the embodiment described in the paragraph number 0016, and the flow control valve is electrically operated. In this embodiment, when the bather senses the bather, the motorized flow control valve denoted by reference numeral 342 is squeezed to overflow the edge of the bathtub, and when the bather is gone, the motorized flow control valve is opened and the amount of inflow to the present invention is reduced. It can be increased to reduce the overflow from the top of the bathtub.

  Since the structure of the present invention is simple and does not require a power source except for an additional portion such as an effect, it can be applied not only to a floating bathtub but also to a waterscape facility such as an artificial pond.
