Description

{Device for preventing frozen water pipe}

The present invention relates to a device for preventing the freezing of a water pipe by discharging water in a toilet tank of a left-hand side where water is collected for the purpose of discharging manure, and in particular, it prevents waste of water by reducing water discharge for preventing freezing of the water pipe So that it can be easily installed in the water tank without changing the structure of the left-hand side water tank.

If the winter temperature is lowered, there is a problem that the water pipe is frozen and frozen. Especially in the evening when going out for a long time or when the temperature suddenly drops, the water supply is opened and the water is continuously discharged to prevent the water pipe from freezing. As described above, the water in the water pipe is continuously discharged through the water supply and drainage, so that the water pipe can be prevented from being frozen.

On the other hand, the water pipe is connected to the water supply pipe at the left side, and when the water is discharged to the water tank of the left side, water of the water supply pipe is automatically introduced into the water tank. That is, the water pipe is connected to the water supply pipe of the left-hand side, so that the water pipe can be prevented from being frozen even if water is continuously supplied to the water tank through the water pipe.

In the drawings, FIG. 1 is a perspective view showing a general toilet seat, and FIG. 2 is a sectional view showing the inside of a water tank of a toilet seat shown in FIG.

As shown in Fig. 1 and Fig. 2, a seat 10 is mounted on an upper surface of a general toilet seat, and a water tank 20 is fixed on the rear of the toilet seat 1. As shown in Fig. A water supply pipe 21 is located inside the water tank 20 and a drain hole 27 is formed at the bottom of the water tank 20. A hinge-coupled stopper 29 is attached to the drain hole 27. A lever 25 is mounted on the outer side of the water tank 20 and a wire 31 connected to an end of a lever 25 extending into the water tank 20 is connected to the stopper 29, When the stopper 29 is opened, the water collected in the water tank 20 is discharged to the manure container 3 of the left-hand side toilet 1 through the drain port 27. The water discharged to the toilet seat (1) is discharged to the septic tank by water pressure together with the manure.

When the water level in the water tank 20 is lowered, the floating valve 23 mounted on the water supply pipe 21 is opened and water is supplied into the water tank 20 through the water supply pipe 21, The water supply pipe 21 is closed by the floating valve 23.

On the other hand, the overflow pipe 33 is mounted in the water tank 20 in case the supply of water continues due to the failure of the floating valve 23. The upper end of the overflow pipe 33 is positioned higher than the appropriate water level. Therefore, even when the float valve 23 fails and the water level rises, the water level does not exceed the upper end of the overflow pipe 33, thereby preventing the water from being washed out from the water tank.

The structure of a general toilet seat is as described above, and a technique for discharging water filled in a toilet in a toilet seat to prevent freezing is disclosed in Korean Patent Laid-Open Publication No. 10-2013-0007724 (published on January 31, 2013). The contents of the prior art document disclose a structure in which a water control tube formed at the lower portion of the overflow pipe is formed and a water control cap is installed to be opened and closed by screwing the water control tube so as to be adjustable in volume, In this case, there is a problem that the structure of the ordinary toilet seat needs to be changed. That is, in order to prevent the freezing of the left side installed in the home or the office, it is necessary to install the overflow pipe and the water control cap known in Korean Patent Publication No. 10-2013-0007724 after dismantling the existing overflow pipe .

In addition, the anti-freeze structure of the prior art constructed as described above is a structure in which the water-regulating cap is partially loosened to prevent freezing, thereby continuously discharging the water in the water tank through the overflow pipe to prevent freezing.

Therefore, in order to prevent freezing, it is necessary to discharge the water continuously, so there is a problem of waste of water.

FIG. 7 is a conceptual diagram showing an example of a timer. FIG.

As shown in FIGS. 3 and 4, the freeze prevention apparatus 100 includes a timer 110, an underwater pump 120, and a drain pipe 130. Specifically, the timer 110 is located outside the water tank 20, the water pump 120 is located at the inner bottom of the water tank 20, and the water pipe 130 extending from the water pump 120 is located at the overflow pipe 33 ).

In addition, the power source necessary for the operation of the timer 110 and the submersible pump 120 may be supplied with external power through the plug 111, or alternatively, it may operate through a rechargeable battery mounted on the timer. Here, the power supply through the rechargeable battery is not shown in the drawing, but can be replaced with a rechargeable battery in place of the plug in accordance with the operating power of the timer and the operating power of the underwater pump.

In the frost preventing device 100 constructed as described above, the plug 111 supplies power to the timer 110 and the underwater pump 120 in a state where the plug 111 is inserted into the external power supply unit, that is, the household power outlet.

As shown in FIG. 5, the timer 110 supplies power to the submerged pump 120 at every operation cycle selected by the user. For example, the timer 110 is provided with buttons 113a, 113b, and 113c and a power-off button 113d according to operation cycles of 1 hour, 2 hours, and 3 hours, respectively, When the corresponding button 113d is pressed, the timer 110 supplies power for a predetermined time interval at an interval of one hour to operate the underwater pump 120. [ As an example, if the temperature exceeds -5 ° C, the user sets the operation of the submersible pump 120 for the set time by pressing the corresponding button 113c every three hours, The submersible pump is set to operate the submersible pump 120 for a set time every two hours by pressing the corresponding button 113b in two hours. If the submersible pump is below -10 ° C, the corresponding button 113a is pressed in one hour, (120) sets the underwater pump (120) to operate for a set time every hour. When the power-off button 113d is pressed, the power is shut off and the underwater pump 120 stops.

Therefore, if the operation period of the submersible pump 120 is shortened as the temperature is lower, the period of water filling in the water tank 20, that is, the water flow period of the water pipe, is shortened to prevent the water pipe from freezing.

4, the water in the water tank 20 is supplied to the overflow pipe 33 through the water pipe 130 extending from the underwater pump 120 while the underwater pump 120 operates according to the set period. . The water drained by the overflow pipe (33) is collected in the manure container (3) of the toilet seat (1).

When the water is drained by the operation of the underwater pump 120, the water level of the water tank 20 is lowered. When the floating valve 23 opens the water supply pipe 21, water in the water supply pipe And is introduced into the water tub 20.

Here, the operation cycle of the timer 110 is shown as an example, and the operation cycle can be changed according to characteristics of each region and country. Also, the underwater pump and the timer can be integrally formed, and the timer can be configured as an analog type or a digital type inputting with a button. You can set the operation period of the submersible pump through the timer and also set the operation time of the submersible pump.
