Description

Technical Field

[0001] The present invention relates to a probe module of an ultrasonic detection device, and more particularly, to a probe module of an ultrasonic detection device, which is equipped with a lower probe module, wherein the lower probe module is arranged below an object and detects the object by generating ultrasonic waves from below the object to the object. Background Art

[0002] An ultrasonic testing device is a device that irradiates an object with ultrasonic waves through a probe module, then uses the probe module to receive reflected or transmitted ultrasonic waves and form an image. Ultrasonic testing devices can detect minute defects, so ultrasonic testing devices require high resolution.

[0003] The ultrasonic detection method using the ultrasonic detection device requires a transmission medium for transmitting ultrasonic waves. Liquid is used as the ultrasonic transmission medium to prevent ultrasonic attenuation, and the commonly used liquid is water.

[0004] The existing ultrasonic detection method is to fill the water tank with water, place the product in the filled water, and then place the probe module above the object. The detection can be performed while part of the object is immersed in the filled water.

[0005] However, the conventional ultrasonic detection device equipped with a probe module above the object has the following problems: In the conventional ultrasonic detection device, the probe module that irradiates ultrasonic waves and receives reflected signals is arranged only in one direction, for example, above the object.

[0006] In the existing ultrasonic detection device, the probe module is arranged above the object, so the detection is performed above the object. However, in the object that needs to be detected above and below, if the detection is performed only above the object, it is necessary to scan below the object by reversing and moving the object after scanning above the object.

[0007] As described above, when an ultrasonic inspection device equipped with a probe module only above an object is used for inspection, a long process time is required due to inverting and moving the object. In addition, when alignment is performed by inverting and moving the object after scanning above the object, the signal processing data above and below the scanned object cannot be processed in conjunction due to position alignment tolerance.

[0008] Furthermore, if bubbles are mixed in water (which is the ultrasonic transmission medium of the ultrasonic detection device), ultrasonic attenuation may occur due to the bubbles. However, the existing ultrasonic detection device has a problem in that it is not equipped with a separate device for removing bubbles in the water supplied to the transmission medium.

[0044] Common terms such as dictionary definitions should be interpreted as having meanings consistent with the meanings in the relevant technical context, and should not be interpreted as idealized or overly formal meanings unless otherwise explicitly defined in various embodiments of the present invention.

[0045] The present invention relates to a probe module of an ultrasonic detection device, which is equipped with a lower probe module, which is arranged below an object and detects the object by generating ultrasonic waves from below the object to the object.

[0046] The probe module of the ultrasonic detection device according to the embodiment of the present invention is used to detect an object (10), and can detect the object (10) by irradiating ultrasonic waves to the object (10) and then using the ultrasonic waves reflected or transmitted by the probe module structure. The object (10) can be various products as long as they can be subjected to ultrasonic detection.

[0047] The probe module of the ultrasonic detection device according to the embodiment of the present invention comprises a lower probe module (100) which is arranged below the object (10). Figure 1 and Figure 2 The lower probe module (100) comprises a lower housing (110), a lower transducer (120), a lower water jacket (130), and a lower liquid injection unit (140).

[0048] The lower housing (110) may be a housing of the lower probe module (100). The lower housing (110) may be disposed below the object (10), the lower transducer (120) may be disposed on the lower housing (110), and the lower housing (110) may be connected to a mobile device and move in the x, y, and z directions.

[0049] like Figure 1 As shown, when in the measurement state of the object (10) to be detected, the lower housing (110) can move in a direction close to the object (10). Figure 2 As shown, when in a state to be measured, the lower housing (110) can move in a direction away from the object (10).

[0050] According to an embodiment of the present invention, the position of the lower transducer (120) equipped on the lower housing (110) can be moved by moving the lower housing (110).

[0051] The lower transducer (120) is provided on the lower housing (110) and can generate ultrasonic waves to the object (10) or receive ultrasonic waves below the object (10). The lower transducer (120) is a device capable of generating ultrasonic waves, and ultrasonic waves can be irradiated below the object (10) through the lower transducer (120).

[0052] In addition, ultrasonic waves can also be received through the lower transducer (120). Specifically, the lower transducer (120) can also be used as a receiving unit and receive ultrasonic waves introduced into the lower transducer (120).

[0053] The lower water jacket (130) is provided with an internal space, into which one side of the lower transducer (120) can be inserted, and the internal space of the lower water jacket (130) can be filled with liquid.

[0054] If the ultrasonic wave generated by the lower transducer (120) is to be transmitted to the object (10), a transmission medium is required, and the transmission medium may be composed of a liquid. The inner space of the lower water jacket (130) may be filled with the transmission medium (composed of a liquid), and the transmission medium may be water. In the following, the transmission medium is described as water.

[0055] One side of the lower transducer (120) may be arranged in the inner space of the lower water jacket (130). The lower water jacket (130) may be equipped with a lower discharge unit (131), and the lower discharge unit (131) may be a through hole formed from the inside of the lower water jacket (130) toward the object (10).

[0056] According to an embodiment of the present invention, liquid can be sprayed toward an object through the lower water jacket (130) for detection without immersing the object in liquid (which is a transmission medium for transmitting ultrasonic waves). Specifically, liquid can be sprayed through the lower discharge unit (131) of the lower water jacket (130), and the sprayed liquid can be transmitted to the object (10) as a transmission medium.

[0057] The ultrasonic wave generated from the lower transducer (120) may be irradiated to the object (10) through the lower discharge unit (131). Figure 3 The water filling the inner space of the lower water jacket (130) is discharged together through the lower discharge unit (131) of the lower water jacket (130).

[0058] The water may be a transmission medium for transmitting ultrasonic waves, which is discharged through the lower discharge unit (131), and the ultrasonic waves generated from the lower transducer (120) may be irradiated to the object (10) through the water discharged by the lower discharge unit (131).

[0059] The water discharged through the lower discharge unit (131) can be moved to a water tank (160), and the water moved to the water tank (160) can be moved to the lower liquid injection unit (140) to be described later by a pump or the like, and the water tank (160) is provided outside the lower shell (110).

[0060] Reference Figure 4 The lower liquid injection unit (140) can inject liquid into the inner space of the lower water jacket (130). The lower liquid injection unit (140) can be connected to a hose or the like extending to the outside, and the liquid can move to the lower liquid injection unit (140) through the hose.

[0061] The liquid moved to the lower liquid injection unit (140) moves to the inner space of the lower water jacket (130) through the lower liquid injection unit (140). The liquid injected into the inner space of the lower water jacket (130) through the lower liquid injection unit (140) may be water.

[0062] Reference Figure 5 , the lower liquid injection unit (140) according to an embodiment of the present invention includes a lower nozzle (141) and a lower bubble exhaust hole (150).

[0063] The lower nozzle (141) is connected to the inner space of the lower water jacket (130) and can be a nozzle through which liquid flows. The lower nozzle (141) is provided inside the lower liquid injection unit (140), and water can be injected into the lower water jacket (130) through the lower nozzle (141).

[0064] The lower bubble discharge hole (150) is connected to the lower nozzle (141). Specifically, the lower bubble discharge hole (150) may be a hollow tube provided above the lower nozzle (141), and one end of the lower bubble discharge hole (150) may be connected to the lower nozzle (141).

[0065] The lower bubble discharge hole (150) can be used to remove bubbles from the water flowing through the lower nozzle (141). The water flowing through the lower nozzle (141) is a transmission medium for transmitting the ultrasonic waves generated by the lower transducer (120). If bubbles are formed in the water stored in the lower nozzle (141), ultrasonic attenuation may occur due to the bubbles.

[0066] The lower bubble discharge hole (150) is used to prevent this phenomenon from occurring. The lower bubble discharge hole (150) may be provided above the lower nozzle (141), and bubbles may be removed from the water flowing through the lower nozzle (141) through the lower bubble discharge hole (150).

[0067] Specifically, when bubbles are generated in the water, the bubbles move to the upper part of the water. The water with bubbles can be discharged through the lower bubble discharge hole (150) provided above the lower nozzle (141), thereby removing the bubbles from the water passing through the lower nozzle (141).

[0068] Reference Figure 4 and Figure 5 The lower bubble discharge hole (150) includes a first bubble discharge hole (151) and a second bubble discharge hole (152). The first bubble discharge hole (151) is connected to the lower nozzle (141) and extends to the upper side of the lower nozzle (141). The first bubble discharge hole (151) can extend vertically from the upper side of the lower nozzle (141).

[0069] The second bubble discharge hole (152) is connected to the first bubble discharge hole (151), and extends horizontally or obliquely downward from one end of the first bubble discharge hole (151). Figure 3 and Figure 4 , water may be discharged from the lower discharge unit (131) of the lower water jacket (130).

[0070] At this time, when the lower air bubble discharge hole (150) includes only the first air bubble discharge hole (151) extending vertically, water discharged from the lower discharge unit (131) is likely to be introduced into the lower air bubble discharge hole (150). When water is introduced into the lower air bubble discharge hole (150), it is difficult to remove air bubbles from the water moving to the lower liquid injection unit (140) through the lower air bubble discharge hole (150).

[0071] In order to prevent this, the second bubble discharge hole (152) extends horizontally or obliquely downward from one end of the first bubble discharge hole (151). Since the second bubble discharge hole (152) extends horizontally or obliquely downward from one end of the first bubble discharge hole (151), water discharged from the lower discharge unit (131) can be prevented from being introduced into the lower bubble discharge hole (150).

[0072] Reference Figure 5 The lower nozzle (141) may be provided with a lower mesh filter (142). The lower mesh filter (142) may filter foreign matter present in the water flowing through the lower nozzle (141).

[0073] Reference Figure 5 The lower nozzle (141) includes a lower micro-nozzle unit (143), and the lower micro-nozzle unit (143) is equipped with a plurality of micro-tubes. The lower micro-nozzle unit (143) is equipped with a plurality of micro-tubes, and water flowing through the lower nozzle (141) passes through the lower micro-nozzle unit (143).

[0074] The plurality of microtubes provided on the lower micronozzle unit (143) can extend in the same direction and in a direction parallel to the direction in which the lower nozzle (141) extends.

[0075] The lower micro nozzle unit (143) is used to form a laminar flow. When the water flowing through the lower nozzle (141) passes through the lower micro nozzle unit (143), the water flows through the lower micro nozzle unit (143) to form a laminar flow.

[0076] The water introduced into the inner space of the lower water jacket (130) by flowing through the lower nozzle (141) may be a transmission medium for transmitting the ultrasonic wave generated by the lower transducer (120).

[0077] When the water introduced into the inner space of the lower water jacket (130) through the lower nozzle (141) generates turbulent flow, it may be difficult for the lower transducer (120) to accurately irradiate the ultrasonic wave to a designated position of the object (10).

[0078] The lower micro-nozzle unit (143) is used to prevent this phenomenon from occurring. Water flowing through the lower nozzle (141) through the lower micro-nozzle unit (143) can form a laminar flow, thereby being able to accurately irradiate the ultrasonic wave generated from the lower transducer (120) to a designated position of the object (10).

[0079] Reference Figure 5 A lower buffer space (144) may be provided between the lower nozzle (141) and the internal space of the lower water jacket (130) and the lower micro-nozzle unit (143), and the diameter of the lower buffer space (144) is greater than or the same as the diameter of the lower micro-nozzle unit (143).

[0080] Specifically, the water introduced into the lower nozzle (141) passes through the lower micro-nozzle unit (143) (on which a plurality of micro-tubes are provided), and then passes through the lower buffer space (144) (on which a plurality of micro-tubes are not provided) and is introduced into the interior of the lower water jacket (130).

[0081] The lower buffer space (144) can be used to prevent the water forming the laminar flow from mixing with each other. When the water passing through the lower micro nozzle unit (143) is directly introduced into the lower water jacket (130), the flow space of the water is expanded, thereby the water forming the laminar flow can mix with each other.

[0082] Furthermore, when the diameter of the connection point between the lower nozzle (141) and the inner space of the lower water jacket (130) is smaller than the diameter of the lower micro-nozzle unit (143), part of the water forming the laminar flow may collide with the side wall.

[0083] The lower buffer space (144) is used to prevent this phenomenon from occurring. The water passing through the lower micro nozzle unit (143) (on which a plurality of micro tubes are provided) is introduced into the interior of the lower water jacket (130) after passing through the lower buffer space (144) (on which a plurality of micro tubes are not provided), thereby preventing the water forming the laminar flow from mixing with each other.

[0084] In the above description, the lower bubble discharge hole (150) of the lower water jacket (130) and the lower liquid injection unit (140) are equipped with the lower mesh filter (142), the lower micro-nozzle unit (143), and the lower buffer space (144), but may not be equipped with the lower bubble discharge hole (150), the lower mesh filter (142), the lower micro-nozzle unit (143), and the lower buffer space (144) as needed.

[0085] The probe module of the ultrasonic detection device according to the embodiment of the present invention comprises an upper probe module (200) which is arranged above the object (10). That is, the probe module of the ultrasonic detection device according to the embodiment of the present invention can simultaneously perform detection above and below the object (10) by means of the lower probe module (100) arranged below the object (10) and the upper probe module (200) arranged above the object (10).

[0086] Reference Figure 1 and Figure 2 The upper probe module (200) comprises an upper housing (210), an upper transducer (220), an upper water jacket (230), and an upper liquid injection unit (240).

[0087] The upper housing (210) may be a housing of the upper probe module (200). The upper housing (210) may be arranged above the object (10), the upper transducer (220) may be arranged on the upper housing (210), and the upper housing (210) may be connected to a mobile device and move in the x, y, and z directions.

[0088] like Figure 1 As shown, when in the measurement state of the object (10) to be detected, the upper housing (210) can move in a direction close to the object (10). Figure 2 As shown, when in a state to be measured, the upper housing (210) can move in a direction away from the object (10).

[0089] According to an embodiment of the present invention, the position of the upper transducer (220) equipped on the upper housing (210) can be moved by moving the upper housing (210).

[0090] The upper transducer (220) is provided on the upper housing (210) and can generate ultrasonic waves to the object (10) above the object (10). The upper transducer (220) can generate ultrasonic waves or receive ultrasonic waves. The upper transducer (220) is a device capable of generating ultrasonic waves, and ultrasonic waves can be irradiated above the object (10) through the upper transducer (220).

[0091] In addition, ultrasonic waves can also be received by the upper transducer (220). Specifically, the upper transducer (220) can also be used as a receiving unit and receive ultrasonic waves introduced into the upper transducer (220).

[0092] The upper water jacket (230) is provided with an internal space, into which one side of the upper transducer (220) can be inserted, and the internal space of the upper water jacket (230) can be filled with liquid.

[0093] If the ultrasonic wave generated by the upper transducer (220) is to be transmitted to the object (10), a transmission medium is required, and the transmission medium may be composed of a liquid. The inner space of the upper water jacket (230) may be filled with the transmission medium (composed of a liquid), and the transmission medium may be water. In the following, the transmission medium is described as water.

[0094] One side of the upper transducer (220) may be arranged in the inner space of the upper water jacket (230). The upper water jacket (230) may be equipped with an upper discharge unit (231), and the upper discharge unit (231) may be a through hole formed from the inside of the upper water jacket (230) toward the direction of the object (10).

[0095] According to an embodiment of the present invention, the upper water jacket (230) can be used to spray liquid onto an object for detection without immersing the object in liquid (which is a transmission medium for transmitting ultrasonic waves). Specifically, the liquid can be sprayed through the upper discharge unit (231) of the upper water jacket (230), and the sprayed liquid can be transmitted to the object (10) as a transmission medium.

[0096] The ultrasonic wave generated from the upper transducer (220) may be irradiated to the object (10) through the upper discharge unit (231). Figure 3 The water filling the internal space of the upper water jacket (230) is discharged together through the upper discharge unit (231) of the upper water jacket (230).

[0097] The water may be a transmission medium for transmitting ultrasonic waves, which is discharged through the upper discharge unit (231), and the ultrasonic waves generated from the upper transducer (220) may be irradiated to the object (10) through the water discharged by the upper discharge unit (231).

[0098] The water discharged through the upper discharge unit (231) can be moved to the water tank (160), and the water moved to the water tank (160) can be moved to the upper liquid injection unit (240) to be described later by a pump or the like, and the water tank (160) is provided outside the upper shell (210).

[0099] Reference Figure 6 The upper liquid injection unit (240) can inject liquid into the inner space of the upper water jacket (230). The upper liquid injection unit (240) can be connected to a hose or the like extending to the outside, and the liquid can move to the upper liquid injection unit (240) through the hose.

[0100] The liquid moved to the upper liquid injection unit (240) passes through the upper liquid injection unit (240) and moves to the inner space of the upper water jacket (230). The liquid injected into the inner space of the upper water jacket (230) through the upper liquid injection unit (240) may be water.

[0101] Reference Figure 7 , the upper liquid injection unit (240) according to an embodiment of the present invention includes an upper nozzle (241) and an upper bubble exhaust hole (250).

[0102] The upper nozzle (241) is connected to the inner space of the upper water jacket (230) and can be a nozzle through which liquid flows. The upper nozzle (241) is provided inside the upper liquid injection unit (240), and water can be injected into the upper water jacket (230) through the upper nozzle (241).

[0103] The upper bubble discharge hole (250) is provided on the upper water jacket (230), and the upper bubble discharge hole (250) extends from the inner space of the upper water jacket (230).

[0104] Specifically, the upper bubble discharge hole (250) may be a tube provided above the upper water jacket (230) and having a hollow interior, and one end of the upper bubble discharge hole (250) may be in communication with the upper water jacket (230).

[0105] The upper bubble discharge hole (250) is used to remove bubbles from the water stored in the internal space of the upper water jacket (230). The water stored in the upper water jacket (230) is a transmission medium for transmitting ultrasonic waves generated by the upper transducer (220). If bubbles are formed in the water stored in the upper water jacket (230), ultrasonic attenuation may occur due to the bubbles.

[0106] The upper air bubble discharge hole (250) is used to prevent this phenomenon from occurring, and the air bubbles stored in the water of the upper water jacket (230) can be removed through the upper air bubble discharge hole (250).

[0107] Specifically, when bubbles are generated in the water, the bubbles move to the upper part of the water. The water with bubbles can be discharged through the upper bubble discharge hole (250) provided above the upper nozzle (241), thereby removing the bubbles from the water passing through the upper nozzle (241).

[0108] The upper bubble discharge hole (250) may be provided above the upper water jacket (230), and water with bubbles formed therein may be removed from the water stored in the inner space of the upper water jacket (230) through the upper bubble discharge hole (250). The upper bubble discharge hole (250) may extend vertically from the upper portion of the upper water jacket (230).

[0109] In addition, the upper bubble discharge hole (250) may be connected to the upper nozzle (241). Specifically, the upper bubble discharge hole (250) may be a hollow tube provided above the upper nozzle (241), and one end of the upper bubble discharge hole (250) may be connected to the upper nozzle (241).

[0110] The upper bubble discharge hole (250) can be used to remove bubbles from the water flowing through the upper nozzle (241). The upper bubble discharge hole (250) can be provided above the upper nozzle (241), and water with bubbles formed can be removed from the water flowing through the upper nozzle (241) through the upper bubble discharge hole (250). The upper bubble discharge hole (250) can extend vertically from the upper nozzle (241) and communicate with the outside.

[0111] Reference Figure 7 The upper nozzle (241) may be provided with an upper filter (242). The upper filter (242) may filter foreign matter present in the water flowing through the upper nozzle (241).

[0112] Reference Figure 7The upper nozzle (241) includes an upper micro-nozzle unit (243), and the upper micro-nozzle unit (243) is equipped with a plurality of micro-tubes. The upper micro-nozzle unit (243) is equipped with a plurality of micro-tubes, and water flowing through the upper nozzle (241) passes through the upper micro-nozzle unit (243).

[0113] The plurality of microtubes provided on the upper micronozzle unit (243) can extend in the same direction and in a direction parallel to the direction in which the upper nozzle (241) extends.

[0114] The upper micro-nozzle unit (243) is used to form a laminar flow. When the water flowing through the upper nozzle (241) passes through the upper micro-nozzle unit (243), the water flows through the upper micro-nozzle unit (243) to form a laminar flow.

[0115] The water introduced into the inner space of the upper water jacket (230) by flowing through the upper nozzle (241) may be a transmission medium for transmitting the ultrasonic wave generated by the upper transducer (220).

[0116] When the water introduced into the inner space of the upper water jacket (230) through the upper nozzle (241) generates turbulent flow, it may be difficult for the upper water jacket (230) to accurately irradiate ultrasonic waves to a designated position of the object (10).

[0117] The upper micro-nozzle unit (243) is used to prevent this phenomenon from occurring. Water flowing through the upper nozzle (241) through the upper micro-nozzle unit (243) can form a laminar flow, thereby being able to accurately irradiate the ultrasonic wave generated from the upper transducer (220) to a designated position of the object (10).

[0118] Reference Figure 7 An upper buffer space (244) may be provided between the connecting portion between the upper nozzle (241) and the internal space of the upper water jacket (230) and the upper micro-nozzle unit (243), and the diameter of the upper buffer space (244) is greater than or the same as the diameter of the upper micro-nozzle unit (243).

[0119] Specifically, the water introduced into the upper nozzle (241) passes through the upper micro-nozzle unit (243) (on which a plurality of micro-tubes are provided), and then passes through the upper buffer space (244) (on which a plurality of micro-tubes are not provided) and is introduced into the interior of the upper water jacket (230).

[0120] The upper buffer space (244) can be used to prevent the water forming the laminar flow from mixing with each other. When the water passing through the upper micro nozzle unit (243) is directly introduced into the upper water jacket (230), the flow space of the water is expanded, thereby the water forming the laminar flow can mix with each other.

[0121] Furthermore, when the diameter of the connection point between the upper nozzle (241) and the internal space of the upper water jacket (230) is smaller than the diameter of the upper micro-nozzle unit (243), part of the water forming the laminar flow may collide with the side wall.

[0122] The upper buffer space (244) is used to prevent this phenomenon from occurring. The water passing through the upper micro nozzle unit (243) (on which a plurality of micro tubes are provided) is introduced into the interior of the upper water jacket (230) after passing through the upper buffer space (244) (on which a plurality of micro tubes are not provided), thereby preventing the water forming the laminar flow from mixing with each other.

[0123] In the above description, the upper bubble discharge hole (250) of the upper water jacket (230) and the upper liquid injection unit (240) are equipped with the upper filter (242), the upper micro-nozzle unit (243), and the upper buffer space (244), but may not be equipped with the upper bubble discharge hole (250), the upper filter (242), the upper micro-nozzle unit (243), and the upper buffer space (244) as needed.

[0124] Reference Figure 8 The probe module of the ultrasonic detection device according to the embodiment of the present invention further includes a liquid supply unit (300).

[0129] The liquid discharge unit (330) discharges liquid from the liquid storage tank (310). The liquid stored in the liquid storage tank (310) may be discharged through the liquid discharge unit (330), and the liquid discharged through the liquid discharge unit (330) may be supplied to the lower liquid injection unit (140) or the upper liquid injection unit (240).

[0130] The liquid discharge unit (330) may be equipped with a micro nozzle unit (350), and the micro nozzle unit (350) may be equipped with a plurality of micro tubes. Figure 8 The micro nozzle unit (350) is equipped with a plurality of micro tubes, and the liquid flowing from the liquid discharge unit (330) passes through the micro nozzle unit (350).

[0131] The plurality of microtubes provided on the micronozzle unit (350) may extend in the same direction and in a direction parallel to the direction in which the liquid discharge unit (330) extends.

[0132] The micro nozzle unit (350) is used to form a laminar flow. When the water flowing through the liquid discharge unit (330) passes through the micro nozzle unit (350), the water flows through the micro nozzle unit (350) to form a laminar flow.

[0133] However, as required, the liquid storage tank (310) and the liquid discharge unit (330) may not be provided with the filter (360), or the filter (360) may be provided in the liquid injection unit (320).

[0134] According to an embodiment of the present invention, the liquid stored in the liquid storage tank (310) may be water.

Specifically, the bubble discharge hole (340) may be a hollow tube provided on the top of the liquid storage tank (310), and one end of the bubble discharge hole (340) may be connected to the liquid storage tank (310).

[0135] The bubble discharge hole (340) is used to remove bubbles from the water stored in the internal space of the liquid storage tank (310). The water stored in the liquid storage tank (310) is a transmission medium for transmitting the ultrasonic wave generated by the lower transducer (120) or the upper transducer (220). When bubbles are formed in the water stored in the liquid storage tank (310), ultrasonic attenuation may occur due to the bubbles.

[0136] The bubble discharge hole (340) is used to prevent this phenomenon from occurring, and bubbles can be removed through the bubble discharge hole (340) before water is supplied to the lower liquid injection unit (140) or the upper liquid injection unit (240).

[0137] Specifically, when bubbles are generated in the water, the bubbles move to the upper part of the water. The water with bubbles can be discharged through the bubble discharge hole (340) provided above the liquid storage tank (310), thereby removing the bubbles before supplying water to the lower liquid injection unit (140) or the upper liquid injection unit (240).

[0138] The bubble discharge hole (340) may be provided above the liquid storage tank (310), and bubbles can be removed from the water stored in the inner space of the liquid storage tank (310) through the bubble discharge hole (340). The bubble discharge hole (340) vertically extends from the top of the liquid storage tank (310).

[0139] Reference Figure 8 The liquid storage tank (310) and the liquid discharge unit (330) may be provided with a filter (360). The filter (360) may filter foreign matter present in the water stored in the liquid storage tank (310) and the water flowing through the liquid discharge unit (330).
