Description

TECHNICAL FIELD [0001] The present invention relates to a water level detection system and a method for detecting a water level in a water tank,

The present invention relates to a water level sensing system and a sensing method for a water tank of a hot water scrubber, and more particularly, to a water level sensing system and a sensing method thereof, The present invention relates to a water level detection system and method for an excellent hot water scrubber water tank.

Generally, a hot water washer or bidet is installed on the upper part of the toilet body, and is used as a device for spraying the washing water through the nozzle device and wiping the genitals and the anus after the toilet. The hot water scrubber filters the washing water supplied from the water source and stores it in the water tank.

When the user's post-use anal cleansing nozzle button or local cleansing nozzle button is selected, the cleansing water stored in the water tank is sprayed in the form of water through the anal cleansing nozzle or the local cleansing nozzle selected by water pressure. The jetted cleanser cleans the anus or the local part of the user.

In such a hot water scrubber, the water tank is provided with a water level sensing device for sensing the water level of the water contained therein. In the conventional level sensing apparatus, a reed switch is provided inside the sensing rod, and a float in which a magnet is inserted is provided on the outer surface of the sensing rod. In the conventional water level sensing apparatus having such a configuration, the reed switch and the float interact to sense the water level inside the water tank. However, according to the conventional water level sensing apparatus, due to the product limit of the reed switch, it is difficult to detect a stable water level in the water tank.

Or, conventionally, the operation of the switch is determined by the magnetic force attached to the ball, which causes an error in the detection of the level depending on the position of the switch.

In addition, according to the conventional water level sensing apparatus, it is difficult to detect an abnormal state only when the water level reaches an abnormality such as a case where a water hole is formed in a water tank and water in the water is continuously leaked. Therefore, even if the water in the water tank is lowered to the abnormal minimum level below the low water level, the heater which heats the water in the water tank continues to operate, so there is a danger of fire and the failure or breakage of the apparatus may be caused.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a system for detecting a level of a water tank of a hot water washing machine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram of a water level detection system of a hot water washer water tank according to an embodiment of the present invention; FIG.

The water level sensing system 100 of the hot water washer water tank according to an embodiment of the present invention determines whether the water tank is leaking, whether the water tank is defective or stably washed through two non-contact type sensors, (100), comprising a first sensor (110), a second sensor (120) and a control unit (130).

In the water tank T, the washing water supplied from the water source is filtered and stored, and water is moved toward the nozzle side by the water pressure when the user drives the nozzle. Inside the water tank T, a heater (not shown) for heating the filtered water is incorporated.

2 is a view showing a positional relationship of sensors of a water level sensing system of a hot water washer water tank according to an embodiment of the present invention.

The first sensor 110 is for sensing the water contained in the water tank T and is mounted on the water tank T and specifically disposed below the water outlet formed on the water tank T. [

The first sensor 110 senses whether or not water is present at a position mounted on the water tank T, and the sensed information is transmitted to the controller 130.

The second sensor 120 is for sensing the water contained in the water tank T such as the first sensor 110 and is mounted on the water tank T and specifically below the first sensor 110 Respectively. That is, as shown in FIG. 2, the second sensor 120, the first sensor 110, and the outlet H are arranged from the bottom of the water tank T.

The second sensor 120 senses whether or not water exists at a position mounted on the water tank T, and the sensed information is transmitted to the controller 130.

In this embodiment, the first sensor 110 and the second sensor 120 are provided as non-contact type water level sensors. By providing the non-contact type water level sensor, it is possible to prevent an error due to the position change due to buoyancy.

The control unit 130 receives sensing information from the first sensor 110 and the second sensor 120 and determines whether the water tank T is leaking or whether the first sensor 110 and the second sensor 120 are defective or not, And it is a structure for providing such information to the user.

First, when water is supplied from the water source into the water tank T, water starts to flow from the lower portion of the water tank T. At this time, water is firstly sensed in the second sensor 120 disposed at a relatively lower position, and water is also sensed in the first sensor 110 as water is continuously supplied.

When both the first sensor 110 and the second sensor 120 transmit water detection information to the controller 130, the controller 130 determines that the water is normally supplied. On the other hand, when water detection information is received from the first sensor 110, the controller 130 controls the water supply valve (not shown) of the water tank T to be closed. Accordingly, the water is maintained at a predetermined height higher than the first sensor 110 and maintained at the water level near the outlet H.

If the first sensor 110 does not receive the sensing information of the water even after the predetermined time has elapsed since the second sensor 120 receives the sensing information of the water, the controller 130 determines that the first sensor 110 is defective And provides bad information to the user. Here, the defect means that the first sensor 110 is not capable of detecting water, such as defects in the manufacturing process or defects in the process of use. When providing bad information to the user, it is not limited such as providing it through an alarm sound or providing bad information through the display.

The water sensing information of the first sensor 110 and the second sensor 120 is continuously supplied to the controller 130 even when water is supplied into the water tank T or water supply to the water tank T is completed . At this time, if the controller 130 receives the water sensing information from the first sensor 110 but does not receive the water sensing information from the second sensor 120, the controller 130 determines that the second sensor 120 is defective, To provide bad information.

If the water sensor T is not provided with the detection information of the water from the second sensor 120 after the lapse of a predetermined time from when the water sensor information is not received from the first sensor 110, . A heater (not shown) is installed inside the water tank T to heat the water. In order to heat the water, the water tank T must always be filled with a predetermined height of water. However, when water detection information is not received from the second sensor 120 after a predetermined time elapses from when the first sensor 110 does not receive the water detection information, it means that there is no water in the water tank T Problems such as tank deformation may occur due to a heater (not shown). In this case, the control unit 130 provides the user with a leak or not, and stops driving the heater (not shown).

Hereinafter, a method of detecting the water level of the hot water washing tank according to one embodiment of the present invention will be described.

FIG. 3 is a method for detecting the level of a water tank of a hot water washer according to an embodiment of the present invention.

Referring to FIG. 3, the water level sensing method (S100) of the hot water washer water tank according to an embodiment of the present invention includes a sensing step (S110), a transmission step (S120), and a determining step (S130).

The sensing step S110 is a step of sensing water in the water tank T through the first sensor 110 and the second sensor 120. [ The first sensor 110 is disposed below the water outlet formed on the water tank T and the second sensor 120 is mounted on the water tank T and is mounted below the first sensor 110. The first sensor 110 and the second sensor 120 are provided as non-contact type water level sensors, each of which detects whether or not water is present at the mounted position.

The transmission step S120 is a step of transmitting the sensing information of the water sensed by the first sensor 110 and the second sensor 120 to the controller 130, respectively. The first sensor 110 and the second sensor 120 continuously transmit the detection information to the control unit 130 when water is sensed, but not when the water is not sensed.

The determining step S130 is a step of determining whether or not the water tank T is leaked or whether the first sensor 110 and the second sensor 120 are defective or stable cleaning through the controller 130. [

FIG. 4 is an algorithm for the water level detection method of the water level of the hot water washer water tank according to the embodiment of the present invention.

Watering stage

When water is supplied from the water source into the water tank (T), water starts to flow from the lower part of the water tank (T). At this time, water is firstly sensed in the second sensor 120 disposed at a relatively lower position, and water is also sensed in the first sensor 110 as water is continuously supplied.

When both the first sensor 110 and the second sensor 120 transmit water sensed information to the controller 130, the controller 130 determines that the water has been properly supplied and the water supply valve Time) is closed. Accordingly, the water is maintained at a predetermined height higher than the first sensor 110 and maintained at the water level near the outlet H.

If the first sensor 110 does not receive the sensing information of the water even after the predetermined time has elapsed since the second sensor 120 receives the sensing information of the water, the controller 130 determines that the first sensor 110 is defective And provides bad information to the user. The bad information may be provided through an alarm sound, a display, or the like.

On the other hand, if water detection information is not received from the second sensor 120 but water detection information is provided from the first sensor 110, it is impossible to detect the presence of water at the position of the second sensor 120, 130 determines that the second sensor 120 is defective and provides the user with defect information.

FIG. 5 is an algorithm for determining the leakage of a water level detection method of a hot water washer water tank according to an embodiment of the present invention.

Leak judgment

It is determined that the sensor information is normal when the sensing information is received from the first sensor 110 and the second sensor 120 after the water supply is completed.

If the controller 130 does not receive the detection information of the water from the second sensor 120 after a predetermined time elapses from when the first sensor 110 does not receive the detection information of the water, . A heater (not shown) is installed inside the water tank T to heat the water. In order to heat the water, the water tank T must always be filled with a predetermined height of water. If there is no water in the water tank (T), problems such as tank deformation may occur due to a heater (not shown). In this case, the control unit 130 provides the user with a leak or not, and stops driving the heater (not shown).

Therefore, according to the present invention, a water level detection system and a method of detecting a water level of a hot water washing tank in which a water tank leak, a sensor failure, or a stable cleaning are judged through two non-contact type sensors is provided.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
