Description

[Detailed description of the invention] This invention relates to a scale precipitation prevention device for a humidifier, and more specifically, it relates to a scale precipitation prevention device for a humidifier in which a scale precipitation preventive agent is periodically dropped into a humidifier. .

Since electric humidifiers heat water and generate steam, hard components in the water become concentrated, reaching solubility and causing scale to precipitate.

Therefore, it is no exaggeration to say that the performance and lifespan of a humidifier are determined by the amount of scale deposited.

In general, the concentration rate varies depending on the amount of water held and the amount of humidification, but
It is usually effective to blow water every few hours.

However, even with this, ingredients such as calcium carbonate are 100%
Since the solubility is very low at ℃, the effect is small, and if used for a long time, a considerable amount of scale will precipitate.

In recent years, water treatment technology has advanced and scale precipitation inhibitors (dispersants, etc.)
It has become possible to prevent scale precipitation even at high concentrations (above the solubility) by administering . is difficult.

The purpose of this invention is to prevent scale precipitation in the humidifier described above, and a water tank containing a scale precipitation preventive agent is provided inside the casing, and a level meter communicating with the water tank is protruded outside the casing. A hose connected to the bottom outlet of the aquarium via a solenoid valve is installed vertically outside the housing, and a timer for operating the solenoid valve is provided inside the housing, and an adjustment knob for this timer is provided. The present invention provides a scale precipitation prevention device for a humidifier, characterized in that the device protrudes outside the casing.

An embodiment of this invention shown in the drawings will be described in detail below.

Figure 1 is an external view of the scale precipitation prevention device of this invention.
FIG. 2 is a diagram showing the relationship between the cross section and the humidifier.

The scale precipitation prevention device A of this invention has an opening at the top where the scale precipitation preventive agent a is placed in a housing 1 in which mounting parts 3a and 3b are formed on the back plate 2 and a lid 4 is fitted on the top surface. A water tank 5 is fixed between the back plate 2 and the front plate 6 with a suitable mounting member, and the scale precipitation preventive agent is introduced into the evaporation water tank 13 of the humidifier B through the electromagnetic valve 7 at the bottom of the water tank. A hose 8 for dripping is attached,
The solenoid valve is configured to be connected to a power source via a timer 9.

In the figure, 10 is a level meter connected to the water tank 5 and protruding from the side of the housing 1, 11 is a timer adjustment knob attached to the front plate 6 side of the housing 1, 12a and 12b are wiring cords, and 14 is a heater installed in the humidifier evaporation water tank.

The scale precipitation prevention device for a humidifier of this invention is constructed as described above, and in its use, the quality of the makeup water to be put in the humidifier evaporation water tank 13, the amount of water held in the humidifier and the evaporation water tank, The capacity and blowing interval are confirmed in advance, and the appropriate dosage and dosage interval of the scale precipitation inhibitor are set using the timer adjustment knob 10.

Therefore, the solenoid valve 7 is opened for a predetermined time at regular intervals according to the time set by the timer, and the scale precipitation preventive agent contained in the water tank 5 is dripped into the humidifier evaporation water tank 13 via the hose 8.

The remaining amount of the scale precipitation preventive agent in the water tank can be visually checked using the level meter 10, and if the remaining amount becomes low, the lid 4 can be opened and the agent can be replenished from the water tank opening. If the power source of the humidifier and the power source of the scale deposition prevention device can be opened and closed using the same power on/off switch, only the scale deposition prevention device will not operate when the humidifier is out of operation.

Although the figure shows only the case where the scale precipitation preventive agent is directly poured into the water tank 5, the scale precipitation preventive agent (dispersant) is used in a very small amount (usually 10 ppm to 50 ppm per administration).
), it would be even more convenient to handle if it were of a cartridge type, which allows the scale precipitation preventive agent to be supplied by inserting the scale precipitation preventive agent container into the water tank.

As mentioned above, this invention provides a water tank containing a scale precipitation preventive agent inside the casing, a level meter that communicates with the water tank protrudes outside the casing, and a solenoid valve at the bottom outlet of the water tank. A hose connected through the casing is installed vertically outside the casing, and a timer for operating the solenoid valve is provided inside the casing, and an adjustment knob for this timer is provided protruding outside the casing, making the device itself compact. unity,
It can be used with any existing humidifier, and it is easy to set the dripping amount and dripping time interval of the scale precipitation preventive agent, and because it is done automatically, it has the effect of reducing the labor required for management. .
