Description

[Detailed Description of the Invention] The present invention relates to a low tank suitable for supplying make-up water to a hot water storage tank of a private parts cleaning device installed alongside a toilet bowl and used to clean the user's private parts with hot water.

Local cleaning devices have become widely used.
This washing device heats washing water supplied from a low tank and is activated by a predetermined operation to spray hot water in a shower shape from a nozzle extending in the toilet bowl. The hot water supply mechanism in this cleaning device is roughly divided into instant heating type and hot water storage type.
In these comparisons, the hot water storage type is preferable in consideration of stability of hot water temperature, amount of hot water discharge, etc. The hot water storage type is further divided into the water pressure type and the pump pressurization type depending on the hot water jetting method.The water pressure type has the disadvantage that it cannot be used at low pressure because the hot water is pushed out and spouted by the water pressure of the makeup water. Therefore, a pump pressurization type is used, but in the case of a pump pressurization type, it is not affected by water pressure, but it cannot be directly connected to the water mains by law.
Considering the case where hot water is used continuously, it is necessary to replenish the hot water tank with more than the maximum continuous hot water usage amount to prevent the pump from idling. The drawback was that if the tank became empty, it would have a negative effect on the pump, etc. Therefore, there is a need for a low tank that can reliably supply the necessary amount of water to the hot water tank of the cleaning device, that can also simultaneously supply water for flushing the toilet bowl, and that does not affect the supply amount from each other.

The present invention was proposed in view of the above circumstances, and provides a water supply mechanism that can reliably supply water to the hot water tank even when the cleaning device is used continuously for a long time, and can also reliably supply water for toilet flushing. We propose a low tank with That is, the low tank is equipped with a toilet bowl cleaning tank and a water supply tank to the private cleaning device, the water supplied to the low tank is supplied to the water supply tank, overflow water from the water supply tank is supplied to the toilet bowl cleaning tank, and the water in the toilet bowl cleaning tank is This is a low tank characterized by a weight suspended in the water supply tank via a chain from the lever part of the ball tap connected to the floating ball of the ball tap or the floating ball support rod.

Examples will be described according to the drawings. The figure is a sectional view of a low tank according to the present invention. The inside of the low tank 1 is formed by dividing a toilet bowl cleaning tank 2 and a water supply tank 3 to a hot water tank by a partition wall 4. A ball tap 5 is attached to the low tank 1 in connection with the water main. The ball tap 5 has a valve body 6 and a floating ball 8 fixed to the other end of a support rod 7 whose one end is attached to the valve body 6.
The floating ball 8 is placed in the toilet bowl cleaning tank 2, and the support rod 7 is displaced by the operation of the floating ball 8, which moves up and down as the water level in the tank 2 fluctuates, and the valve portion 6 is moved accordingly.
The valve is moved toward and away from the valve seat to supply and shut off water. The water supply port 9 of the ball tap 5 is opened to discharge water into the water supply tank 3, and the water supply tank 3 is only connected to the delivery pipe 10 to the hot water tank (not shown) of the private parts cleaning device on the bottom, and is in a full state. When this happens, the overflowing water will overflow into the tank 2 for flushing the toilet bowl. Therefore, when the water level in the toilet bowl cleaning tank 2 decreases, the ball tap 5 is opened and water is first discharged into the water supply tank 3 until the water supply tank 3 is filled with water until the overflowing water raises the inside of the toilet bowl cleaning tank 2 to a predetermined water level. Water will be supplied. A chain 12 is attached to an arbitrary position of the lever part 11 of the ball tap 5 or the support rod 7, and a weight 13 is attached to the other end of the chain 12, and the weight 13 is suspended in the water tank 3. The weight 13 has a specific gravity of 1, but is not particularly limited, and a weight with a specific gravity close to 1 is used. Next, the movement inside the water supply tank 3 will be explained. By using the local cleaning device, water is sent to the hot water tank through the delivery pipe 10, and the water level in the water supply tank 3 gradually decreases. Since the weight 13 has a specific gravity close to 1, it does not have any effect while submerged in water, but when the water level drops and the weight 13 is exposed, the weight of the weight 13 may cause the mounting position of the support rod 7 etc. to change. Since the floating ball 8 is lowered, the ball tap 5 is opened and the water tank 3 is replenished. Replenishment of the water tank is completed when the water rises to a predetermined level at which the weight 13 sinks and does not act as a load on the support rod 7, etc., and the pole tap 5 closes. When cleaning the toilet bowl, the float valve 14 is opened by a predetermined operation such as a lever, the water stored in the toilet bowl cleaning tank 2 is released, the water level in the tank 2 is lowered, and the ball tap 5 is opened, and the water supply tank is first opened. However, since the water supply tank 3 is full, the water immediately overflows into the toilet cleaning tank 2, and water is discharged until the tank 2 reaches a predetermined water level. Close and stop supplying.

As described above, the low tank according to the present invention allows immediate replenishment of the hot water tank of the device even if the device is used continuously, and moreover, it is substantially possible to replenish water separately from the water supply for cleaning the toilet bowl. can. Moreover, one low tank can supply for both purposes, there is no need for a two-system supply structure, and there is no need for extra space equipment. In addition, it can be supplied continuously, and the pump operates without idling, reducing troubles in the pump system and allowing stable use over a long period of time. In addition, water can be supplied to the low tank by simply adding a weight to a conventional ball tap, and it is highly reliable and low-cost, without unnecessarily complicating the mechanism. This is a device with great practical value, as it can provide the following effects.
