Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a waterproof pan in which a water faucet having an adjustable flow rate is provided at a position where it can be easily handled and a water discharge port is provided at an inconspicuous position.

[0002]

2. Description of the Related Art A waterproof pan is intended to prevent a drain of the washing machine from invading the floor while placing a washing machine on it. In recent years, however, it is troublesome to provide a water faucet with an adjustable flow rate. There are various types of pipes that can omit the in-wall piping. For example, Japanese Patent Laid-Open No. 9-170249,
JP-A-9-60066 and JP-A-10-18376.
Japanese Patent Laid-Open No. 11-61923, Japanese Patent Laid-Open No. 2000
Japanese Patent Publication No. 179014 discloses such a waterproof pan with a water faucet.

On the other hand, the Applicant of the present invention further installs a water faucet with a flow rate adjusting function in the front corner of the rectangular pan body to improve its operability and is connected to the water supply section of the washing machine. We have developed a so-called multifunctional waterproof pan, by locating the spout at the back side corner of the pan body so that the connecting hose between the water supply part and spout can be arranged inconspicuously and the appearance is improved. (Patent application 2000-312
219).

[0004]

However, the above-mentioned waterproof pan developed by the present applicant still has a problem to be solved. That is, in the waterproof pan integrally provided with the water faucet and the spout, it is necessary to connect the both inside the pan body. According to the waterproof pan of the applicant, a flexible pipe made of resin is used as the connecting pipe. Was planned. This is because it is inexpensive and can be freely routed inside the bread body. Therefore, the applicant of the present invention bends the flexible pipe for connecting the water faucet / water spout inside the bread main body to provide a surplus, and when connecting the spout to the washing machine, the surplus flexible pipe is used. A means is also adopted that enables the connection by pulling out the bread from the bread body.

However, the flexible pipe has a lower strength than the metal pipe, and the excess flexible pipe is drawn out every time the spout is connected to the washing machine. Therefore, the fatigue of the flexible pipe is great.

The present invention has been made in view of the above problems, and an object thereof is to connect a water faucet and a water spout with a durable metal tube while specifying them at positions that are easy to use and look good. Is to provide a highly reliable waterproof pan.

[0007]

In order to achieve the above-mentioned object, in the present invention, a water faucet is provided on a flat surface above a corner of a waterproof pan body which is three-dimensionally molded by raising its peripheral edge in a generally rectangular plan view shape. In addition to the above, a water outlet is provided on a plane above another corner that is connected to the corner at one side, and the water tap and the water outlet are connected by a straight tubular metal pipe arranged inside the waterproof pan body. Was used. It should be noted that it is preferable that the drainage port is provided at the center of the waterproof pan body, because interference with the metal pipe can be avoided, but if the positions do not interfere with each other, the drainage port is formed at the center of the waterproof pan body. Not limited.

In the second aspect, the copper pipe is used as the metal pipe connecting the water tap and the spout. The copper tube is more preferably a phosphorus-deoxidized copper seamless tube.

In the third aspect, the water discharge port is a one-touch coupler having a water stop function.

BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan view of a waterproof pan according to one embodiment of the present invention, in which a drain 20 is formed in the center of a substantially rectangular waterproof pan body 10. Further, pedestals 30 ... 30 on which legs of a washing machine are placed are formed at four corners of the waterproof pan body 10. Since this pedestal 30 ... 30 is raised from the bottom of the main body,
Even if water leaks from the drain port 20, it can be stopped. Further, a protruding edge portion 40 that is raised more than the pedestals 30 ... 30 is three-dimensionally formed on the four circumferences of the waterproof pan body 10 so as to surround the pedestals 30. 50 ...
Numeral 50 is a fixing screw hole for fixing the waterproof pan body 10 to the floor of the washing machine storage space, and after fixing the screw, it is appropriately closed with a cap or the like to prevent rusting of the screw.

In the waterproof pan having such a basic structure, if the left side in the figure is the front side and the right side is the rear side, the water faucet 60 with a flow rate adjusting function is provided on the upper plane of the front corner of the waterproof pan body 10. Is provided. Further, a water outlet 70 is provided on the upper plane of the back-side corner that is connected to the corner provided with the water faucet 60 on one side. And, the water tap 60 and the spout 70 are
The waterproof pan main body 10 is connected along one side edge thereof with a straight tubular metal tube 80 disposed therein. In addition,
In this embodiment, the metal tube 80 made of phosphorus deoxidized copper is adopted.

FIG. 2 is an internal detailed view showing the AA cross section of FIG. The water tap 60 has a built-in flow rate adjusting valve 62 that is continuous with a connecting portion 61 that is connected to a water pipe (not shown) disposed under the floor, and only the operation handle 64 of the valve shaft 63 is provided in the waterproof pan body. It has a form exposed from the projecting edge portion 40 of 10. Further, the water flow from the flow rate adjusting valve 62 is performed by the valve body 6
5 through the insertion joint female 66 that is screwed or fitted to the side surface. On the other hand, the insertion joint male 81 is attached to the tip of the metal pipe 80. The insertion joint male 81 is inserted into the insertion joint female 66, and the quick fastener 82 is fitted between both the joints 66 and 81. The metal pipe 80 is connected to the water tap 60 by combining them.

On the other hand, the spout 70 is connected to a metal pipe 80 via a connecting portion 71. Further, in this embodiment, a one-touch coupler 72 is adopted as a structure for connecting the spout 70 and the water supply part of the washing machine. That is, the spout 70
Is connected to the water supply section of the washing machine via another hose (not shown) with a coupler corresponding to the coupler 72. The spout 70 has a built-in water shutoff valve 73, and the water shutoff valve 73 is opened and closed by a water shutoff adapter 74 to allow water to flow only when the one-touch coupler 72 is connected to the hose with the coupler. Is configured as follows. In addition,
In the figure, 75 is a check valve.

As described above, according to the waterproof pan, the water faucet 6
0 is placed in front of the waterproof pan that is easy to operate, and the spout 7
0 is placed on the far side, which is not conspicuous. And both 60
Since 70 is provided at the corners connected to one side of the waterproof pan body 10, both 60 and 60 are provided as compared with the case where they are provided diagonally.
The length of the metal tube 80 connecting 70 is shortened. further,
Since a metal tube 80 is used to connect both 60 and 70,
A water supply structure with excellent durability and reliability can be provided.
Furthermore, the water faucet 60 and the water discharge port 70 are previously connected to the metal pipe 80.
Even if the design of the waterproof pan body 10 is changed, it is possible to handle the connected product as a completed unit product, and since the dimensions are almost standard, this unit product should be incorporated in most of the waterproof pan body. In addition, it can be installed easily.

[0015]

As is apparent from the above description, according to the present invention, the faucet and the spout are easy to use,
In addition, since it is arranged in a good-looking position, and both are connected by a metal tube having excellent durability over time, a water leakage accident can be largely avoided, and a reliable waterproof pan can be provided.
