Description

Humidifier

The present invention relates to a humidifier, and more particularly, to a humidifier that generates humidified air using sterilized water.

A humidifier is a device that vaporizes water and emits humidified air with a high moisture content. A humidifier can vaporize water by natural vaporization, heating vaporization, or ultrasonic vibration to create humidified air.

Each vaporization method has its advantages and disadvantages. In the case of natural vaporization, there is the problem that the user must frequently manage the humidifying medium used.

In the case of vaporization by ultrasonic vibration, there are problems such as the humidified air may not flow actively into the indoor space because the supplied water is atomized by ultrasonic vibration, the problem that unpleasant humidified air may flow into the indoor space if unsterilized water is humidified, and the problem that the ultrasonic vibrator is vulnerable to high temperature.

In the case of heated vaporization, a safety hazard may occur if hot humidified air is directly discharged.

Korean registered patent KR 10-0158806 discloses a humidifier that heats and humidifies water supplied from a water tank using ultrasonic vibration.

However, in the case of the prior literature, a structure is disclosed in which the space for heating water and the space for humidifying are connected to each other. This causes a problem in that the water cannot be completely sterilized when the temperature for heating water is maintained below the set temperature by considering the ultrasonic vibrator. In addition, when the water is heated to be sterilized and sent to the ultrasonic vibrator, there is a problem in that the ultrasonic vibrator may break down. In other words, in the case of the prior literature, it is difficult to completely sterilize and humidify the water.

In addition, in the case of the previous literature, since only sterilization through heating is performed, the ions in the water can still be vaporized while they are still present. In the case of general tap water, small amounts of sterilizing agents such as chlorine, iron, magnesium, calcium, etc. are included, so if these are vaporized directly, they can have a negative effect on the human body.

The problem to be solved by the present invention is to provide a humidifier in which a first humidifying tank for heating water and a second humidifying tank for atomizing water are separated into a structure, and the inside of the second humidifying tank can be kept clean. The problem to be solved by the present invention is to provide a humidifier that generates humidified air using pure water.

Specifically, the invention provides a humidifier that removes ions present in water supplied to a humidifying module and supplies the removed ions to the humidifying module.

In addition, a humidifier is provided in which water stored in a tank flows to a humidifying module only after passing through a water softener.

Another object of the present invention is to provide a humidifier that stably maintains the arrangement of a water softener placed in a tank.

The detection sensor (234) can measure water quality by measuring the electrical conductivity of water. That is, the concentration of ions can be detected by measuring the electrical conductivity of water.

The detection sensor (234) is positioned at the upper portion of the middle supply pipe (230b) and can quickly detect the water quality of the water supplied from the water tank (100). That is, when the water existing in the supply chamber (232) descends and the water of the water tank (100) flows in, the water quality of the water flowing in from the water tank (100) can be detected.

<Humidifier module>

Referring to FIGS. 17 to 22, a humidifying module is described.

The humidifier of the present invention may include a humidifying module that heats water and generates humidified air. The humidifying module may include a first humidifying tank (300) that forms a first chamber (300a) that heats water, and a second humidifying tank (350) that forms a second chamber (350a) that generates humidified air with a vibrator (370). The humidifying module may include a first connecting pipe (390) and a second connecting pipe (392) that connect the first humidifying tank (300) and the second humidifying tank (350).

The humidifier may include a first connecting pipe (390) connecting the first humidifying tank (300) and the second humidifying tank (350), and a second connecting pipe (392). The first connecting pipe (390) may supply water heated in the first humidifying tank (300) to the second humidifying tank (350). Referring to FIG. 17, a second valve (402) is arranged in the first connecting pipe (390). The second valve (402) opens and closes the internal flow path of the first connecting pipe (390), so that water heated in the first humidifying tank (300) may be supplied to the second humidifying tank (350).

Referring to Fig. 18, a pump (404) is arranged in the second connecting pipe (392). When the pump (404) operates, water in the second humidifying tank (350) can flow into the first humidifying tank (300).

The humidifier includes a drain pipe (394) for draining water existing in the first humidifying tank (300), and a drain pipe valve (396) arranged at an end of the drain pipe (394) to open and close the drain pipe (394). Referring to Fig. 17, the drain pipe (394) may be connected to one side of the first humidifying tank (300). The drain pipe valve (396) may be arranged at an end of the drain pipe (394).

The drain pipe (394) can discharge water stored in the first humidifying tank (300) to the outside. The drain pipe (394) can extend to the outside of the humidifying module housing (410, see FIG. 24).

The humidifier includes a first temperature sensor (336) for detecting the temperature of water stored inside the first humidifying tank (300) and a first water level sensor (338) for detecting the water level of water stored inside the first humidifying tank (300). Referring to Fig. 18, the first temperature sensor (336) and the first water level sensor (338) are arranged on one side of the first humidifying tank (300).

The humidifier includes a second temperature sensor (364) for detecting the temperature of water stored inside the second humidifying tank (350) and a second water level sensor (366) for detecting the water level of water stored inside the second humidifying tank (350). Referring to Fig. 17, the second temperature sensor (364) and the second water level sensor (366) are arranged on one side of the second humidifying tank (350).

The humidifier includes a detection sensor (234) that detects the quality of water existing inside the supply pipe (230). Referring to FIG. 17, the detection sensor (234) is arranged on one side of the supply pipe (230). The detection sensor (234) can detect the quality of water flowing from the water tank (100). The detection sensor (234) can detect the quality of water and detect the replacement of the water softener (140) arranged in the water tank (100).

The humidifier may include a notification unit (not shown) that provides a notification to the user, and a data storage unit (not shown) that accumulates and stores water purification level data detected by the detection sensor (234).

When the water purification level detected by the detection sensor (234) is above the set level, the first valve (400) can open the end of the supply pipe (230). When the water purification level detected by the detection sensor (234) is below the set level, the notification unit can operate. The notification unit can provide the user with a notification regarding the replacement of the ion exchange resin placed in the water softener (140).

Here, the setting level of the water purification degree can be preset in the humidifier. The setting level of the water purification degree can also be set differently depending on the standard.

The notification unit can provide the user with a first alarm notifying whether the ion exchange resin needs to be replaced. In addition, the notification unit can provide the user with a second alarm notifying whether the water softener (140) is installed.

When the gradient of the amount of change in the degree of water purification accumulated in the data storage unit is formed within a set range, the notification unit can provide a first notification to notify the replacement of the ion exchange resin stored in the water softener (140).

The gradient of the amount of change in the degree of water purification accumulated in the data storage unit is formed within a set range, which is a problem due to the long-term use of the ion exchange resin, and can provide the first notification.

When the gradient of the amount of change in the degree of purification of water accumulated in the data storage unit is out of the set range, the notification unit can provide a second notification to confirm whether the water softener (140) is installed. The gradient of the amount of change in the degree of purification of water accumulated in the data storage unit being out of the set range may occur due to the non-installation of the water softener regardless of whether the water softener is used. Therefore, the second notification can be used to have the user confirm whether the water softener is installed.

<Water and air flow according to humidifier operation>

Referring to Figure 26, the flow of water and the flow of air in the humidifier of the present invention are explained.

The humidifier of the present invention can store water in a water tank (100). The water tank (100) has a structure that is opened upward, so that upper water supply can be achieved. In addition, the water tank (100) is arranged so as to be detachable from the structure of the humidifier, so that water supply through separation is possible.

The water supplied to the tank (100) can flow to the supply pipe (230) arranged at the bottom. However, the water flowing to the supply pipe (230) arranged at the bottom can be arranged to flow through the water softener (140).

The water softener (140) placed inside the water tank (100) has holes formed at the top and bottom, so that water flowing into the hole formed at the top can be discharged through the hole formed at the bottom. However, a gasket (152) is placed on the periphery of the water softener (140) to prevent water from flowing between the inner water tank (102) and the water softener (140).

Accordingly, water supplied to the tank (100) and flowing into the supply pipe (230) can flow into the supply pipe (230) with the ions in the water removed through the water softener (140). A detection sensor (234) for detecting water quality is placed inside the supply pipe (230). Accordingly, water temporarily stored inside the supply pipe (230) can have its hardness detected by the detection sensor (234).

At this time, the detection sensor (234) can detect the ion removal status of the water stored in the supply pipe (230) to detect the time or whether to replace the water softener (140). The water in the supply pipe (230) is supplied to the first humidifying tank (300) located at the bottom. A first valve (400) can be located between the first humidifying tank (300) and the supply pipe (230).

When the first valve (400) opens the supply pipe (230), water stored in the supply pipe (230) can be supplied to the first chamber (300a) of the first humidifying tank (300).

The water stored in the first humidifying tank (300) can be heated by the heater (340). The first humidifying tank (300) can heat and sterilize the water stored therein. The water heated and sterilized in the first humidifying tank (300) can flow to the second humidifying tank (350).

Humidified air generated as the heater (340) operates in the first humidifying tank (300) can flow to the second humidifying tank (350) through the connecting pipe (310).

When the second valve (402) placed in the first connecting pipe (390) connecting the first humidifying tank (300) and the second humidifying tank (350) is opened, water stored inside the first humidifying tank (300) can flow into the second humidifying tank (350).

In the second humidifying tank (350), humidified air is generated using the water supplied from the first humidifying tank (300). In the second humidifying tank (350), a vibrator (370) is operated to atomize the water stored inside. In addition, flowing air is introduced into the humidifying device by a blower fan (62).

A portion of the air flowing by the blower fan (62) can be introduced into the second humidifying tank (350) to cool the water introduced from the first humidifying tank (300). The humidified air generated in the second humidifying tank (350) can flow into the first discharge path (32) formed between the tank (100) and the inner shell (180).

The air introduced into the second humidifying tank (350) by the blower fan (62) can actively cause the humidified air generated inside the second humidifying tank (350) to flow into the first discharge path (32).

The water stored inside the second humidifying tank (350) can flow to the first humidifying tank (300) through the pump (404). The water remaining in the second humidifying tank (350) can become contaminated if exposed for a long period of time. Therefore, the pump (404) can be operated to flow the water stored in the second humidifying tank (350) to the first humidifying tank (300).

The first humidifying tank (300) can heat and sterilize the water supplied from the second humidifying tank (350). The water remaining in the first humidifying tank (300) can be discharged to the outside through the drain pipe (394). By changing the arrangement of a separate drain pipe valve (396, see FIG. 25), the drain pipe (394) can be opened, and the water stored in the first humidifying tank (300) can be discharged to the outside.

In addition, the air drawn in through the inlet (24a) flows upward through the filter (50). The blower fan (62) rotates inside the case (10) and sends the air drawn in through the inlet (24a) to the outlet (12a). The air flowing through the blower fan (62) can flow through the second discharge path (34). The second discharge path (34) is formed between the inner shell (180) and the outer shell (22), and the air flowing through the blower fan (62) can flow through the second discharge path (34).

The second discharge path (34) is arranged around the first discharge path (32). Therefore, the air discharged to the outlet (12a) can flow as clean air around the humidified air.

Referring to Figure 27, various sensors and valves arranged in each of the first humidifying tank (300) and the second humidifying tank (350), and the operation of the first humidifying tank (300) and the second humidifying tank (350) are described.

The first valve (400) opens the supply pipe (230) so that water can be supplied to the first humidifying water tank wall (302).

The first valve (400) can be operated based on the water level detected by the first water level sensor (338). The first valve (400) can open the supply pipe (230) when the water level detected by the first water level sensor (338) is lower than the set water level.

The first valve (400) closes the supply pipe (230) when the water level detected by the first water level sensor (338) is higher than the set water level. When the second valve (402) opens the first connection pipe (390), the first valve (400) can close the supply pipe (230). Accordingly, water flowing through the first connection pipe (390) can flow as water that has been heated in the first humidifying tank (300).

When water is supplied to the first humidifying tank (300) at a certain level and the first valve (400) closes the supply pipe (230), the heater (340) can operate. The heater (340) heats the water stored in the first humidifying tank (300). The humidified air generated by the operation of the heater (340) can flow to the second humidifying tank (350) through the connecting pipe (310).

When the heater (340) operates, the blower fan (62) can operate. That is, when the heater (340) heats the water stored in the first humidifying tank (300), the blower fan (62) can operate to supply air to the second humidifying tank (350). The blower fan (62) can supply air to the second humidifying tank (350) to cool the inside of the second humidifying tank (350).

The heater (340) can operate until the temperature of the water detected by the first temperature sensor (336) reaches 100 degrees. The water stored in the first humidifying tank (300) is heated to the boiling point and sterilized. When the temperature of the water detected by the first temperature sensor (336) reaches 100 degrees, the second valve (402) opens the first connecting pipe (390). After the temperature of the water detected by the first temperature sensor (336) reaches 100 degrees, the second valve (402) can open the first connecting pipe (390).

The first temperature sensor (336) can be placed at a position equal to or lower than the discharge hole (316). Accordingly, the temperature of the remaining water after the water in the second humidifying tank (350) is discharged through the first connecting pipe (390) can be detected.

When the second valve (402) is opened, water stored in the first humidifying tank (300) flows to the second humidifying tank (350) by gravity. When the second valve (402) is opened, water can move until the water levels of the first humidifying tank (300) and the second humidifying tank (350) become the same. When the second valve (402) is opened, the water level of the first humidifying tank (300) can be lowered to the maximum height of the outlet hole (316) formed in the first humidifying tank (300).

The second valve (402) opens the first connecting pipe (390) when the second water level sensor (366) is lower than the optimal height at which the vibrator (370) of the second humidifying tank (350) can operate. The second valve (402) opens the first connecting pipe (390) when a water level difference between the first humidifying tank (300) and the second humidifying tank (350) detected by the first water level sensor (338) and the second water level sensor (366) is formed.

The second valve (402) can be opened for a set time. That is, it is opened for a set time in consideration of the time when the water levels of the first humidifying tank (300) and the second humidifying tank (350) become equal, and the first connecting pipe (390) can be closed when the actual time has elapsed. The second valve (402) can be opened for a set time in consideration of the time when the water in the first humidifying tank (300) flows to the second humidifying tank (350).

The blower fan (62) can operate while the second valve (402) is open. By operating the blower fan (62), the air flowing into the second humidifying tank (350) can cool the water flowing into the second humidifying tank (350) through the first connecting pipe (390).

The second temperature sensor (364) detects the temperature of water stored in the second humidifying tank (350). The second temperature sensor (364) can detect the temperature of water flowing into the second humidifying tank (350) through the inflow hole (358). The vibrator (370) can operate when the temperature of the water detected by the second temperature sensor (364) is below the set temperature. The set temperature for operating the vibrator (370) can be set in consideration of preventing damage to the vibrator (370).

The second temperature sensor (364) can be placed at the same height as the inlet hole (358) or at a height lower than the inlet hole (358). Accordingly, the temperature of water flowing in through the inlet hole (358) can be detected.

The second water level sensor (366) can detect the water level of the second humidifying tank (350). The second water level sensor (366) can detect the lowest water level of the second humidifying tank (350) where the vibrator (370) does not operate. If the water level of the second humidifying tank (350) detected by the second water level sensor (366) is formed lower than the set water level, the vibrator (370) can stop operating. The lowest water level at which the vibrator (370) stops operating can be determined based on the water level stored in the second humidifying tank (350) compared to the vibration level of the vibrator (370).

The second water level sensor (366) can detect the water level at which the vibrator (370) operates optimally. The second water level sensor (366) can detect the upper and lower water levels at which the vibrator (370) can operate optimally, at a position where the water in the second humidifying tank (350) is higher than the lowest water level at which the vibrator (370) stops operating.

In the second humidifying tank (350), a water level sensor cover (368) is placed between the second water level sensor (366) and the vibrator (370), so that stable water level detection is possible even when the vibrator (370) is in operation.

The vibrator (370) can operate when the water level detected by the second water level sensor (366) is higher than the set water level. The vibrator (370) can include two vibrating elements (372). Therefore, the two vibrating elements (372) can operate individually. The two vibrating elements (372) can operate selectively.

When the vibrator (370) operates, the blower fan (62) can operate. Accordingly, the humidified air generated by the vibrator (370) can be discharged to the outside of the humidifier together with the air flowing from the second humidifying tank (350) to the first discharge path (32) by the blower fan (62). The blower fan (62) can actively promote the flow of the humidified air generated by the vibrator (370).

The vibrator (370) and heater (340) can operate simultaneously. At this time, humidified air generated in the first humidifying tank (300) flows through the second humidifying tank (350) to the first discharge path (32), and humidified air generated in the second humidifying tank (350) can also flow through the first discharge path (32).

The pump (404) causes water in the second humidifying tank (350) to flow into the first humidifying tank (300). The pump (404) can be operated after the operation of the vibrator (370) has stopped. The pump (404) can be operated after the second valve (402) closes the first connecting pipe (390). When the pump (404) operates, the first valve (400) can close the supply pipe (230). When the pump (404) operates, the operation of the blower fan (62) can be stopped.

The recovery discharge hole (360) can be formed at one side of the height where the vibrator (370) is located. The recovery discharge hole (360) is positioned lower than the inflow hole (358) formed in the second humidifying tank (350). The pump (404) is positioned higher than the positions where the recovery discharge hole (360) and the recovery inflow hole (314) are formed. Therefore, water from the second humidifying tank (350) can be sucked in and water can be supplied to the first humidifying tank (300).

The pump (404) can be operated by considering the water level of the first humidifying tank (300) detected by the first water level sensor (338) and the water level of the second humidifying tank (350) detected by the second water level sensor (366). When the water level of the first humidifying tank (300) is above the appropriate water level, the operation of the pump (404) can be prevented.

The water stored in the first humidifying tank (300) can be discharged to the outside through the drain pipe (394). When the drain valve (396) opens the drain pipe (394), the water stored in the first humidifying tank (300) can be discharged to the outside. The drain hole (318) formed in the first humidifying tank (300) can be positioned at the location where the heater (340) is positioned. The water stored between the heater (340) and the first humidifying tank (300) can flow to the drain pipe (394) through the drain hole (318).

<Other examples>

The second valve (402) is placed adjacent to the first humidifying tank (300). The pump (404) is placed adjacent to the second humidifying tank (350).

When the second valve (402) is opened, water in the first humidifying tank (300) can flow into the second humidifying tank (350). In addition, when the pump (404) operates while the second valve (402) is opened, water in the second humidifying tank (350) can flow into the first humidifying tank (300).
