JPH0647380A - Calcium agent replenishment warning device for ionized water producing apparatus - Google Patents

Abstract

PURPOSE:To accurately know the replenishing period of a calcium agent and to make proper calcium ion water drinkable by the proper replenishment of the calcium agent by providing a warning means operated when the lowering quantity of a current value based on the lowering of the concn. of the calcium ion of the water between electrodes becomes a predetermined value or less. CONSTITUTION:When the supply of water is started by opening a tap water cock 3, tap water is purified in a water purifying tank l and the purified water is replenished with calcium by a calcium agent to enter an electrolytic cell 2 to be electrolyzed by electrodes 23, 24 and separated into alkali ion water and acidic water. At this time, calcium is precipitated on the surfaces of the electrodes by electrolysis and the resistance values of the electrodes are increased. When the concn. of the calcium ion in the introduced water lowers by the consumption of the calcium agent, an electrolysis control circuit 35 removes the reduction quantity due to the adhesion of calcium to the surfaces of the electrodes from the output of a current sensor 34 to detect the reduction quantity due to the lowering of the concn. of the calcium ion. When this detected value reaches a predetermined value, a lamp 38 is allowed to light to warn the replenishment of the calcium agent.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a view showing an embodiment of a calcium agent replenishment warning device for an ionized water generator according to the present invention. First, the configuration will be described. In FIG. 1, 1 is a water purification tank and 2 is an electrolysis tank. Raw water such as tap water is introduced into the water purification tank 1 through a water supply pipe 4 having a water tap 3, and then introduced into an electrolysis tank 2 through a connecting pipe 5 to be electrolyzed and then converted into ion water and acid water. To be separated.

FIG. 2 shows an example of the structure of the water purification tank 1. The housing indicated by reference numeral 11 has a water supply pipe connection port 12 at the bottom thereof.
Further, it has a connecting pipe connection port 13 and accommodates a filtering agent unit 14 therein. Further, the calcium agent cassette 15 is inserted through the insertion opening formed at the top of the housing 11. This calcium agent cassette 1
Reference numeral 5 denotes a bottomed cylindrical body 16 having a large number of small holes, and a socket 17 detachably attached to the open end of the cylindrical body 16.
And a calcium agent such as calcium glycerophosphate is filled in the space formed by the cylindrical body 16 and the socket 17. A socket 17 is screwed onto the top end plate of the housing 11 so that the tubular body 16 is located inside the housing 11. Therefore, by removing the socket 17 from the housing 14 and then removing the tubular body 16 from the socket 17, it is possible to replenish the inside with the calcium agent.

In the water purification tank 1 of FIG. 2, the filtering agent unit 14 housed in the housing 11 has a cylindrical body, annular end plates fixed to the upper and lower ends thereof, and a cylinder provided around the cylindrical body. And a filter agent in the shape of a filter, a gap is formed between the end surface and the outer peripheral surface and the inner peripheral surface of the housing 11 so that water can flow. Water supply pipe connection port 12 to housing 11
The water introduced therein passes through the filtering agent toward the center from the gap between the housing 11 and the outer circumferential surface of the filtering agent unit 14, and then flows upward along the outer circumferential surface of the cylindrical body. The socket 17 of the calcium agent cassette 15 has a small hole (not shown) penetrating the upper peripheral wall 17a thereof,
The water that has passed through the filtering agent enters the calcium agent cassette 15 through the small holes, contacts the calcium agent 18, and then
The center hole 14 of the filtering agent unit 14 is penetrated through the cylindrical body 16.
The water flows through a path from a to the connecting pipe connection port 13, and during this time, purified water and calcium supplementation are performed.

The electrolytic cell 2 is also provided with two chambers 22 and 23 separated by a diaphragm 21, and electrodes 22 and 23 are housed in each chamber. And one chamber 21
To take out alkaline ionized water, and acidic water from the other chamber 22.

The means for supplying a current to the electrodes 23, 24 is a transformer 3 for generating a predetermined voltage from an AC power supply 31.
2, a rectifying circuit 33 that rectifies this voltage and applies it between the electrodes 23 and 24, a current sensor 34 that detects a current flowing between the electrodes 23 and 24, an output of the current sensor 34, and a connecting pipe 5. The electrolysis control circuit 35 performs predetermined control based on the output of the temperature sensor 39 provided.
The electrolysis control circuit 35 adjusts the output voltage of the transformer 32 via the voltage adjustment circuit 36 according to the outputs of the current sensor 34 and the temperature sensor 39, and the rectification circuit 33 via the polarity conversion circuit 37. It works to switch the polarity of the output voltage.

The current value flowing between 24 is detected by the current sensor 34, and the applied voltage and the voltage direction are controlled in the current control circuit 35. If the temperature is constant, this current value is highest at the beginning of energization and gradually decreases with the passage of energization time. The causes are that calcium or the like is deposited on the electrode surface by electrolysis to increase the resistance value, and that the calcium ion concentration of the water introduced from the water purification tank 1 decreases due to the consumption of the calcium agent.
