Invention of Claim 4 is the structure which has a normally closed solenoid valve provided in the water supply port of the water purifier, and an electromagnetic valve which opens and closes discharge outside the water purifier body made from the water purifier. An electric water heater with a direct water purifier was realized.

FIG. 1 is a longitudinal sectional view showing a configuration of one embodiment relating to claim 1 of the present invention. The hexagon nut 83 connects the water supply hose 81 connected to a water tap (not shown) and the inlet of the water purifier 51 through a packing 55 by screws. The water purifier 51 is made of activated carbon or a hollow fiber filter. The outlet of the water purifier 51 is screw-connected with a hexagon nut 83 through a packing 55, and the tip of the water purifier 51 is divided into two. One of them is connected to a valve 56, and stops the flow of purified water to the purified water discharge port 57, which is screw-connected to the purified water discharge port 57 via an O-ring 58. The other one reaches the normally closed solenoid valve 62 connected to the water conduit 59 extending to the center of the heating vessel 61, and is connected to the check valve 52 at the inlet of the heating vessel 61 through a water seal via an O-ring 58a. Has been. The purified water in the heating container 61 is heated by the heater 63. The electric pump 70 discharges hot water in the heating container 61 to the hot water outlet 71 through hot water outlets 67 and 68 in the hot water supply pipe 66. The hot water outlet 71 is screw-connected to the outlet of the electric pump 70 with a hexagon nut 83 through an O-ring 58. 69 is a float in the hot water supply pipe 66. Reference numeral 64 denotes a water level detecting means for detecting the water level in the heating container 61. For example, there are those in which the inductance of the coil changes due to the pressure of the water, and a photocoupler. 65 is a temperature detecting means comprising a thermistor or the like. The bottom plate 92 is fixed to the water purifier exterior 94 with screws 93. The magnet 95 is attached to the upper part of the overhanging water purifier exterior 94, and holds the bottom of the exterior 91 as being easily removable.

The operation of this embodiment will be described below. First, when it is desired to use purified water, by opening the valve 56, the raw water from the water tap is purified through the water supply hose 81 and the water purifier 51 and discharged from the purified water discharge port 57.

Next, when using purified hot water, the electric pump 70 is driven and hot water in the heating container 61 is discharged from the hot water outlet 71 only while a hot water switch (not shown) is pressed. By opening and closing the normally closed solenoid valve 62 controlled by the water level detection means 64 attached to the heating vessel 61, the raw water from the water tap becomes purified water through the water supply hose 81 and the water purifier 51, and the water conduit 59 and the check valve. The heating container 61 is filled with water through 52. Therefore, the float 69 in the hot water supply pipe 66 is held at the full water position A, and the hot water supply port 68 is opened. The purified water in the heating container 61 is kept at an appropriate temperature by a heater 63 controlled by a temperature detecting means 65. The passage through the hot water supply port 68 at the upper part of the hot water supply pipe 66 is thick and short, and the passage through the hot water supply port 67 at the lower part of the hot water supply pipe 66 is narrow and long. It discharges to the hot water outlet 71 through the hot water outlet 68. For this reason, the normal temperature purified water flowing into the bottom of the heating vessel 61 from the normally closed electromagnetic valve 62 is not easily mixed with the stored hot water, and the hot water maintained at an appropriate temperature by the heater 63 controlled by the temperature detecting means 65. Can be used.

Next, an operation when the hot water stored in the heating container 61 is used in an arbitrary place where a power source is used will be described. The tip of the check valve 52 is removed upwardly against the magnetic force of the magnet 95 together with the exterior 91 of the heating container 61 from the outlet of the electromagnetic valve 62 that is water-sealed with the O-ring 58a. At this time, since the power supply (not shown) from the heating container 61 side is stopped at the magnet 95, the normally closed electromagnetic valve 62 is closed. By this closing, purified water does not leak from the water conduit 59 which is one outlet of the water purifier 51. In addition, since the check valve 52 allows water to flow only from the electromagnetic valve 62 to the heating vessel 61, hot water in the heating vessel 61 will not leak even if the heating vessel 61 is removed from the O-ring 58a connected to the water seal. Absent. When the heating container 61 is used at an arbitrary place where a power source is used, the lower end of the outer casing 91 of the heating container 61 is located lower than the tip of the check valve 52, so that it can be held flat. The check valve 52 can be replaced with a solenoid valve, and the same function can be achieved by detecting that the heating container 61 has moved upward and removed from the O-ring 58a connected to the water seal, and is closed. When a hot water switch (not shown) is pressed, hot water at an appropriate temperature is discharged, and the hot water in the heating container 61 decreases. As the water level in the heating container 61 decreases, the float 69 descends, and the hot water supply port 68 in the hot water supply pipe 66 is closed and discharged through the hot water supply port 67 to the hot water outlet 71. For this reason, most of the hot water stored in the heating container 61 can be used in any place where power is supplied. The water purifier portion from which the heating container 61 has been removed is protected at its position by the water purifier exterior 94, and the outlet of the electromagnetic valve 62 is protected.

The water purifier 51 is replaced by removing the bottom plate 92 and the water purifier exterior 94 fixed with screws 93, and removing the inlet and outlet of the water purifier 51, which are screw-connected with the hexagon nut 83 via the packing 55. The screw connection method of the hexagon nut 58 of the water seal connection portion by the packing 55 and the O-ring 58 can be also performed by inserting and connecting the split pins at both ends of the joint.

FIG. 2 is a longitudinal sectional view showing the configuration of another embodiment relating to claim 1 of the present invention. The water guide pipe 59 and the normally closed electromagnetic valve 62 are not projected to the center of the heating container 61 but remain on the side surface of the water purifier exterior 94, and the check valve 52 at the inlet of the heating container 61 is projected to the side surface of the exterior 91. The magnet 95 is attached to the lower side surface of the water purifier exterior 94 and holds the exterior 91 side surface of the heating container 61 as being easily removable. The configuration of the water purifier exterior 94 and the exterior 91 of the heating container 61 is simpler than that of the first embodiment. Other configurations are the same as those of the first embodiment.

The operation of this embodiment will be described below. The case where it is desired to use purified water or purified hot water, or the method of replacing the water purifier 51 is the same as in the first embodiment. When hot water stored in the heating container 61 is used at an arbitrary place where a power source is used, the operation of moving only the heating container 61 is removed laterally against the magnetic force of the magnet 95 together with the exterior 91 of the heating container 61.

FIG. 3 is a longitudinal sectional view showing the structure of an embodiment relating to claim 2 of the present invention. The heating container 61 has substantially the same cross-sectional shape as the water purifier 51 on the upper part of the water purifier 51 made of activated carbon or a hollow fiber filter. Each central part is water-sealed through an O-ring 58a and is held without using a magnet. The purified water discharge ports 57-1 and 57-2 are connected to each other via a water seal via an O-ring 58. Other configurations are the same as those of the first embodiment.

The operation of this embodiment will be described below. First, when using purified water, by opening the valve 56, the raw water from the water tap is purified through the water supply hose 81 and the water purifier 51 and discharged from the purified water discharge ports 57-1 and 57-2. The

When it is desired to use purified hot water, it is the same as in the first embodiment.
Next, the operation when using the hot water stored in the heating container 61 at an arbitrary place is to maintain the weight of the hot water stored in the heating container 61 without using a magnet when the heating container 61 is detached. Except for this, it is the same as Example 1. At this time, the purified water discharge port 57-2 can be pushed into the 57-1 so that the total length of the purified water discharge ports 57-1 and 57-2 can be shortened.

The replacement method of the water purifier 51 is the same as that in the first embodiment.

FIG. 4 is a longitudinal sectional view showing the construction of one embodiment relating to claim 3 of the present invention. One-touch desorption between the automatic shut-off function part 82 that stops water when the tip of the water supply hose 81 that connects the water faucet and the water purifier 51 (not shown) is removed and the check valve 52 provided at the inlet of the water purifier 51 It is connected with an adapter 53 that can. The water purifier 51 is made of activated carbon or a hollow fiber filter, and is screwed to the check valve 52 via a packing 55 with a hexagon nut 83. The outlet of the water purifier 51 is screw-connected with a hexagon nut 83 through a packing 55, and the tip of the water purifier 51 is divided into two. One of them is connected to a valve 56 and stops the flow of purified water from the water purifier 51 to the purified water discharge port 57. The other one is directly connected to the electromagnetic valve 62 at the center of the heating vessel 61. Other configurations are the same as those of the third embodiment.

Other operations are the same as those in the third embodiment.

Next, an operation when the hot water stored in the heating container 61 is used in an arbitrary place where a power source is used will be described. When the water supply hose 81 connected to the tip of the automatic shut-off function part 82 is removed from the adapter 53 and the water purifier 51 / heating container 61 is used in any place, the raw water from the water tap is connected to the water supply hose 81. The automatic shut-off function part 82 is stopped. Further, since the check valve 52 passes water only from the adapter 53 in the direction of the water purifier 51, even if the water purifier 51 and the heating container 61 are removed from the adapter 53, the inlet of the water purifier 51 is stopped by the check valve 52. . Thereby, the raw water from a water tap and the purified water in the water purifier 51 do not leak. Other operations are the same as those in the third embodiment.

FIG. 5 is a longitudinal sectional view showing the construction of one embodiment relating to claim 4 of the present invention. A normally closed electromagnetic valve 62a provided at the tip of a water supply hose 81 that connects a water tap and a water purifier 51 (not shown) and the inlet of the water purifier 51 are screw-connected with a hexagon nut 83 via a packing 55. The outlet of the water purifier 51 is screw-connected with a hexagon nut 83 through a packing 55, and the tip of the water purifier 51 is divided into two. One of them is connected to the electromagnetic valve 62b, and stops the flow of purified water from the water purifier 51 to the purified water discharge port 57. The other one is connected to a water conduit 59 that extends to the center of the heating vessel 61. Other configurations are the same as those of the first embodiment.

The operation of this embodiment will be described below. First, when the purified water is to be used, the raw water from the water tap is supplied to the water supply hose 81 by opening the normally closed solenoid valve 62a and the solenoid valve 62b while the water purification switch (not shown) is pressed. The water is purified through the water purifier 51 and discharged from the purified water discharge port 57.

Next, when using purified hot water, the hot water in the heating container 61 is discharged only while the unshown hot water switch is pressed, and the normally closed solenoid valve 62a and the normally closed solenoid valve 62 are opened in conjunction with each other. Thus, the raw water from the water faucet passes through the water supply hose 81 and the water purifier 51 to become purified water, which is replenished and full. Other operations are the same as those in the first embodiment.

Next, an operation when the hot water stored in the heating container 61 is used in an arbitrary place where a power source is used will be described. The tip of the check valve 52 is removed upwardly against the magnetic force of the magnet position sensor 95a together with the exterior 91 of the heating container 61 from the outlet of the electromagnetic valve 62 that is water-sealed with the O-ring 58a. The normally closed electromagnetic valve 62 is closed by the signal of the magnet position sensor 95a.
