Description

[0001] This application is a divisional application of the invention patent application filed on May 18, 2021, with application number 202110538406.5 and entitled "Pet Water Supply Device". Technical Field

[0002] This invention relates to a pet water supply device, and more particularly to a pet water supply device that allows pets to drink water conveniently and prevents foreign objects from accumulating on the top surface of the device. Background Technology

[0003] Recently, pets have been considered members of the family, thus serving as companions. Owners manage their pets by feeding them or providing them with water.

[0004] In particular, pets need water to maintain their biological rhythms. Due to the social lives of their owners, pets are often left alone at home, leading to the development of water supply devices that can provide clean water to pets.

[0005] As an existing water supply device, Korean Patent Publication No. 10-20-0033132 is disclosed.

[0006] In the existing water supply system, a water supply pipe and a water supply plate are installed in the center of the inner side of the water tank. With this structure, the increased height of the water supply plate may make it difficult for pets to drink. Furthermore, dust, hair, and other foreign matter may accumulate in the water tank, making frequent cleaning of the water supply system inconvenient. Summary of the Invention

[0007] The present invention was proposed to solve the above-mentioned problems, and its purpose is to provide a pet water supply device that allows pets to drink water easily, arouses pets' curiosity about water, and minimizes the accumulation of foreign objects on the upper surface of the top plate.

[0008] A pet water supply device according to the present invention for achieving the above-mentioned objectives includes: a water tank for containing water; a pump for circulating the water in the water tank; a top plate, a discharge section and a water storage section formed on one side and the other side respectively, and formed such that the width increases from the one side to the other side, the discharge section for discharging water supplied from the pump, and the water storage section being recessed and formed at a position lower than the discharge section for storing water discharged through the discharge section; a filter section configured to filter the water in the water storage section and then allow it to flow into the water tank; an upper housing on which the top plate is disposed, allowing water overflowing from the water storage section to flow into the filter section through the space between the upper housing and the top plate; a main housing surrounding the outside of the water tank; and a sensing unit that supplies power to the pump when the upper housing is disposed on the upper part of the main housing, and stops supplying power to the pump when the upper housing is removed from the main housing.

[0009] According to the present invention, the position of the water storage section that stores water discharged from the discharge section can be lowered, thereby making it easier for pets to drink water.

[0010] Furthermore, it maximizes the width of water flow on the upper surface of the top plate, thereby preventing foreign matter from accumulating on the upper surface of the top plate.

[0011] Furthermore, the water flows in a wave-like pattern on the upper surface of the top plate, which arouses the pet's curiosity and encourages the pet to drink enough water.

[0012] Furthermore, the top plate is designed to slope downwards towards the front and to be wider towards the front, thus creating a structure that allows the pet to clearly see the flow of water when viewed from the front, thereby arousing curiosity and encouraging the pet to drink.

[0013] Furthermore, without the upper housing installed, power is stopped from supplying the light source and pump, thereby protecting the breeder's eyes from the light from the light source and preventing unnecessary operation of the pump.

[0014] Furthermore, it is equipped with an overflow prevention hole, which prevents water from overflowing to the outside of the water supply device even if the filter is clogged. Attached Figure Description

[0024] Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] Reference Figures 1 to 7 The pet water supply device 1 according to the present invention includes: a water tank 150 for containing water; a pump 130 for circulating the water in the water tank 150; a top plate 120, with a discharge section 121 and a water storage section 122 formed on one side and the other side, respectively, the discharge section 121 for discharging water supplied from the pump 130, and the water storage section 122 being formed at a position lower than the discharge section 121 for storing water discharged through the discharge section 121; filter sections 141 and 142, configured to filter the water in the water storage section 122 and then allow it to flow into the water tank 150; and a control section 105, including the pump 130, for controlling the pet water supply device 1.

[0027] Hereinafter, when referring to directions, the side where the discharge section 121 is located will be referred to as the rear, and the other side where the water storage section 122 is located will be referred to as the front.

[0028] The water tank 150 is configured as a bucket or box shape with an open top, thereby containing water in its internal space. The outside of the water tank 150 is surrounded by the main body shell 100.

[0029] The bottom surface of the main housing 100 is open, and a lower cover 101 is attached to cover the open bottom surface of the main housing 100.

[0030] The main body shell 100 and the water tank 150 can be made of synthetic resin and integrally formed by injection molding. In this case, the upper end of the main body shell 100 and the upper end of the water tank 150 can be connected by the connecting part 102.

[0031] The pump 130 operates to draw in water stored inside the water tank 150 and supply it to the water storage section 122 of the top plate 120. For this purpose, the inlet of the pump 130 is connected to the water tank 150, and the outlet of the pump 130 is connected to the outlet pipe 131.

[0032] A pump inlet filter 133 is provided between the inlet of the pump 130 and the water tank 150 to filter the water flowing into the pump 130. The pump inlet filter 133 is recessed downward from the bottom 150a of the water tank 150 and is inserted into and positioned in a lower open filter insertion portion 150c. A pump connection member 135 for connecting to the pump side is provided at the lower part of the filter insertion portion 150c, and an O-ring 134 for maintaining airtightness is sandwiched between the bottom surface of the filter insertion portion 150c and the pump connection member 135. Because of the pump inlet filter 133, foreign matter can be prevented from entering the pump 130, thereby preventing pump malfunction and preventing noise generated when the pump 130 is operating due to foreign matter.

[0033] The outlet pipe 131 is configured as a piping shape with a length in the vertical direction, and the internal space 131a serves as a flow path for the water supplied by the pump 130. The lower end of the outlet pipe 131 is connected to the pump 130, and the upper end 131b is connected to the discharge part 121 of the top plate 120. The outlet pipe 131 can be integrally formed on the outside of the water tank 150.

[0034] When viewed in a plan view, the top plate 120 has a shape that gradually widens from the side forming the discharge section 121 to the other side forming the water storage section 122, and is configured as a triangular shape with rounded corners. That is, it is configured as a shape that is narrow at the rear and wide at the front. Here, "width" refers to the width in the left-right direction perpendicular to the line connecting the front and rear.

[0035] As described above, if the width of the top plate 120 is configured to gradually increase from the discharge section 121 to the water storage section 122, the width of the water discharged from the discharge section 121 will increase towards the water storage section 122, thereby forming a larger width on the upper surface of the top plate 120 and flowing.

[0036] Therefore, even if pet hair or dust accumulates on the upper surface of the top plate 120, it can be cleaned by water flowing with a wide width, thus keeping the upper surface of the top plate 120 clean.

[0037] Furthermore, the top plate 120 is configured to slope downwards from one side to the other, such that the portion where the discharge section 121 is formed is higher, while the portion where the water storage section 122 is formed is located at a lower position than the discharge section 121. If configured as described above, the position of the water storage section 122 can be lowered, thereby making it easier for the pet to drink water.

[0038] The discharge section 121 is recessed to form a discharge space 121a inside. It is configured as a funnel shape, wider at the top and narrower at the bottom, with an open bottom to allow water supplied by the pump 130 to flow in. The discharge space 121a can hold a predetermined amount of water supplied by the pump 130.

[0039] If the discharge section 121 is not formed into a discharge space 121a but is only configured as a through hole through the top plate 120, the water supplied by the pump 130 will splash into the upper space due to the discharge pressure as it passes through the through hole, resulting in water scattering to the outside of the water supply device.

[0040] In this invention, a discharge space 121a for containing water is formed in the discharge section 121. So if water flows into the discharge section 121 through the water outlet pipe 131 by means of the operation of the pump 130, a predetermined amount of water is contained in the discharge space 121a. The contained water plays a buffering role to prevent water that continuously flows into the discharge space 121a by means of the operation of the pump 130 from splashing into the upward space.

[0041] Water discharged from the discharge section 121 flows to the water storage section 122, which is formed into a concave shape with a protruding lower part in order to store the water.

[0042] A flow section 123 is formed between the discharge section 121 and the water storage section 122 to allow water discharged from the discharge section 121 to flow into the water storage section 122. The flow section 123 may be shaped to slope downward from the rear towards the front in the direction of water flow.

[0043] The flow section 123 may have a pair of protrusions 124 that protrude upwards along the width direction of the flow section 123. In this embodiment, the case of two protrusions 124 is illustrated, but one or more may also be present. Due to the protrusions 124, the water flowing down from the discharge section 121 can be made to rise like waves as it passes over the protrusions 124, thereby arousing curiosity and encouraging the pet to drink the water.

[0044] And, as Figure 5 As shown in (c), the flow section 123 can be configured with a high central portion and low side edges in the width direction. If configured as described above, the water flowing from the discharge section 121 toward the water storage section 122 flows in a manner that diffuses to the side edges, thus allowing it to flow with the widest possible width on the upper surface of the top plate 120. Therefore, the upper surface of the top plate 120 can be cleaned and kept clean.

[0045] The protrusion 124 can be formed to have a relatively long length along the width direction of the top plate 120. When there are multiple protrusions 124, the protrusions can be formed to have different lengths. Furthermore, when there are two protrusions 124, the protrusion located in front can be formed to be longer than the protrusion located behind. Furthermore, when there are three or more protrusions 124, they can be formed to increase in length towards the front. If configured as described above, water can flow with the widest possible width, corresponding to the increased width of the top plate 120.

[0046] The upper surface of the top plate 120 can be surface treated to increase its surface roughness. If the water discharged from the discharge section 121 is to flow towards the water storage section 122 with the widest possible width, the water needs to maintain a shape that diffuses widely in the width direction.

[0047] The smoother the upper surface of the top plate 120, the greater its hydrophobicity to water. As a result, when water discharged from the discharge section 121 flows toward the water storage section 122, it gathers close to the center line connecting the discharge section 121 and the water storage section 122, thus causing the width of the flowing water to decrease.

[0048] To prevent the phenomenon described above, if a surface treatment is performed to increase the roughness of the upper surface of the top plate 120, the surface area in contact with water increases, thereby increasing the hydrophilicity of the upper surface of the top plate 120.

[0049] The upper surface of the top plate 120 can be surface-treated by sandblasting. Sandblasting is a method of surface treatment that uses compressed air or other methods to forcefully spray water containing polishing materials such as abrasive or steel shot onto the surface of the material. Preferably, glass protrusions, which are particles of glass material, are used as the abrasive material for surface treatment.

[0050] The top plate 120 can be made of synthetic resin or stainless steel. When the top plate 120 is made of stainless steel, the risk of bacterial growth is lower, thus preventing contact allergies and acne in pets.

[0051] The water outlet pipe 131 and the discharge section 121 are connected by the discharge section connecting component 132.

[0052] The discharge section connecting component 132 includes a discharge section connecting portion 132a connected to the lower end of the discharge section 121, a water outlet pipe connecting portion 132b connected to the upper end 131b of the water outlet pipe 131, and a through hole 132c that passes through the central portion of the discharge section connecting portion 132a and the water outlet pipe connecting portion 132b.

[0053] The discharge section connecting portion 132a is configured as an elliptical plate shape, and a recessed portion 132e is formed inwardly around the outer periphery of the discharge section connecting portion 132a. The lower end portion 121b of the discharge section 121 is inserted into the recessed portion 132e to achieve locking, thereby realizing the connection between the discharge section connecting member 132 and the discharge section 121.

[0054] The outlet pipe joint 132b is configured as a pipe shape extending downward from the lower end of the discharge joint 132a. A lower end protrusion 132f is formed around the lower end of the outlet pipe joint 132b, protruding outward. This lower end protrusion 132f engages with the outlet pipe protrusion 131c, which protrudes inward from the inner side of the upper end of the outlet pipe 131, thereby achieving the connection between the discharge connecting member 132 and the outlet pipe 131. When the discharge connecting member 132 is connected to the top plate 120, if the lower end protrusion 132f of the discharge connecting member 132 is connected to the outlet pipe protrusion 131c of the outlet pipe 131, the top plate 120 will remain fixed in position and will not move.

[0055] As the upper surface of the discharge section joint 132a, with the through hole 132c as a reference, a discharge section protrusion 132d that protrudes upward more than the upper surface of the top plate 120 is formed at the opposite end of the water storage section 122.

[0056] The discharge section protrusion 132d is configured in the shape of a thumb to facilitate gripping by hand, and is recessed towards the water storage section 122, while its opposite side is formed protrudingly.

[0057] The discharge section protrusion 132d functions as a handle, facilitating the separation of the top plate 120 and the discharge section connecting member 132 from the water outlet pipe 131. Furthermore, the discharge section protrusion 132d guides water flowing through the through hole 132c and the discharge space 121a towards the front of the water storage section 122 and blocks flow towards the rear, which is the opposite direction.

[0058] On the front surface of the discharge portion protrusion 132d, a pair of protrusions 132g, which have a horizontal length and protrude forward, can be formed. Because of these protrusions 132g, it is easy to grasp them by hand and pull them upwards.

[0059] In this embodiment, the discharge portion protrusion 132d and the discharge portion connecting member 132 are integrally formed, but the discharge portion protrusion 132d may also be configured to protrude upward from the upper surface of the top plate 120 at a position opposite to the discharge portion 121, with the discharge portion 121 as the reference. Even with the configuration described above, the rearward flow of water through the through hole 132c and the discharge space 121a can be blocked, and the handle function for separating the top plate 120 from the water outlet pipe 131 can also be performed.

[0060] The filter sections 141 and 142 are used to filter foreign objects before water overflowing from the water storage section 122 of the top plate 120 flows into the water tank 150, and include a primary filter 141 and a secondary filter 142 for secondary filtration of the water passing through the primary filter 141.

[0061] The primary filter 141 is used to filter larger foreign objects such as pet hair and can be constructed using a pre-filter.

[0062] The secondary filter 142 can be made of non-woven fabric and activated carbon, and can be used to remove fine particles and residual chlorine.

[0063] The upper part of the main housing 100 is provided with an upper housing 110 on which the top plate 120 is mounted and for supporting the filter parts 141, 142.

[0064] The upper housing 110 includes: a main body 111 configured in a shape corresponding to the shape of the top plate 120 for mounting the top plate 120; a housing flange 112 extending downward around the edge of the main body 111; and a filter support 113 formed in the center of the main body 111 and supporting the filter parts 141 and 142.

[0065] The main body 111 may be configured to be inclined downward from rear to front in a manner corresponding to the shape of the top plate 120, and has a side wall portion 111b extending upward around the edge portion.

[0066] The sidewall portion 111b corresponds to the shape of the top plate 120, thereby arranging the top plate 120 in the internal space surrounded by the main body portion 111 and the sidewall portion 111b.

[0067] Multiple mounting protrusions 111a for supporting the bottom surface of the top plate 120 protrude upward from the front and rear sides of the main body 111. If the bottom surface of the top plate 120 is placed on the mounting protrusions 111a, the bottom surface of the top plate 120 is separated from the upper surface of the main body 111.

[0068] If water stored in the water storage section 122 of the top plate 120 overflows through the edge of the top plate 120, it flows through the space between the bottom surface of the top plate 120 and the upper surface of the main body 111.

[0069] If the upper housing 110 is placed on the main housing 100, the lower end of the housing flange 112 is supported by the upper surface edge of the main housing 100.

[0070] The filter support portion 113 is formed by recessing the central portion of the main body portion 111 downwards, and is configured as a circle corresponding to the shape of the primary filter 141 and the secondary filter 142. A plurality of through holes 113a are formed in the filter support portion 113 to allow water passing through the primary filter 141 to flow to the secondary filter 142.

[0071] The primary filter 141 is disposed on the upper surface of the filter support 113, and the secondary filter 142 is attached to the bottom surface of the filter support 113.

[0072] The top plate 120, upper housing 110, primary filter 141, and secondary filter 142 are arranged in a stacked structure, allowing for easy disassembly and assembly. Therefore, the breeder can conveniently disassemble and clean the components, and easily replace the primary filter 141 and secondary filter 142.

[0073] A water outlet through hole 114 is formed at the rear of the main body 111, through which the upper end 131b of the water outlet pipe 131 passes.

[0074] Multiple overflow prevention holes 115 are formed on both sides of the central portion of the main body 111. The overflow prevention holes 115 may be located above the primary filter 141, or they may be formed below the upper end of the side wall portion 111b.

[0075] If the primary filter 141 or the secondary filter 142 becomes clogged, water overflowing from the water storage section 122 of the top plate 120 fills the space surrounded by the main body section 111 and the side wall section 111b. If the water level exceeds the upper end of the side wall section 111b, water overflows to the outside of the main body housing 100. In the case of the present invention, since the overflow prevention hole 115 is formed, even if the upper part of the main body section 111 is full of water, the water will fall into the water tank 150 through the overflow prevention hole 115, thereby preventing water from overflowing to the outside of the main body housing 100.

[0076] A space is formed between the water tank 150 and the main housing 100 and the lower cover 101. The space is equipped with the pump 130, a sterilization unit 161 for sterilizing the water inside the water tank 150, a battery 163 for supplying power, a water level sensor 164 for sensing the water level inside the water tank 150, and a control unit 105.

[0077] The sterilization unit 161 can be constructed using an LED that irradiates ultraviolet light into the interior space of the water tank 150. Preferably, it is constructed using UV-C, which has an excellent sterilization effect among the types of ultraviolet light.

[0078] The sterilization unit 161 includes: a fixed housing 161d, fixed to the bottom surface of the bottom 150a of the water tank 150; a substrate 161a, fixed to the lower part of the fixed housing 161d by a fastening member 161e and equipped with an LED as a light source; a transmission member 161b, made of glass, which allows the light from the light source to be transmitted into the interior space of the water tank 150; and a sealing member 161c, sandwiched between the edge of the transmission member 161b and the inner side of the fixed housing 161d to prevent water from the water tank 150 from leaking to the substrate 161a side.

[0079] A pair of downwardly protruding bosses 150b are formed on the bottom surface of the bottom 150a of the water tank 150. The two ends of the fixed housing 161d are connected to the bosses 150b by fastening components (not shown). The fixed housing 161d is inserted into the through hole 150d formed in the bottom 150a of the water tank 150.

[0080] An open portion 161f communicating with the internal space of the water tank 150 is formed in the upper center of the fixed housing 161d, and a light-emitting element of the substrate 161a is provided in the lower part of the open portion 161f. When the sterilization unit 161 is activated, ultraviolet light emitted from the light-emitting element passes through the open portion 161f and irradiates the water inside the water tank 150, thereby sterilizing the water contained in the water tank 150.

[0081] The upper surface of the transmission component 161b is in contact with the water in the water tank 150 filled in the opening 161f, and the transmission component 161b blocks the water to prevent the water in the opening 161f from falling onto the substrate 161a, while allowing the light of the light-emitting body to be transmitted.

[0082] An O-ring 162 can be clamped between the inner side of the boss 150b and the outer side of the fixed housing 161d to prevent water inside the water tank 150 from leaking into the lower part of the sterilization section 161.

[0083] The battery 163 can be a rechargeable battery, allowing the pet water dispenser 1 to operate without a separate power supply. As described above, if equipped with the battery 163, it operates wirelessly, eliminating the need for a power cable, allowing the pet water dispenser 1 to be placed in the desired location for use. Furthermore, in addition to the battery 163, it can also be configured to receive power from an external source to operate the pet water dispenser 1.

[0084] The water level sensor 164 is used to sense whether the water level inside the water tank 150 is below the set water level and is in a state of insufficient water. If the pump 130 operates in a state of insufficient water, problems such as shortened lifespan of the pump 130 may occur. Therefore, the control unit only controls the pump 130 to operate when the water level set by the water level sensor 164 is above the set water level.

[0085] The water level sensor 164 is a non-contact type. If the water level inside the tank 150 drops to the set level, the resistance value sensed by the water level sensor 164 changes. If the changed resistance value indicates that the water level is below the set level, the pump 130 stops operating. In this case, a low water level warning can be issued.

[0086] If the pump 130 operates when the upper housing 110 is not positioned above the main housing 100, water supplied from the pump 130 will be discharged directly through the outlet pipe 131, potentially causing the discharged water to escape to the outside of the main housing 100. Furthermore, when the upper housing 110 is not positioned above the main housing 100, if the light-emitting element of the sterilization section 161 emits light, the light can directly illuminate the eyes of the keeper after passing through the interior of the water tank 150. Therefore, it is preferable to stop the power supply when the upper housing 110 is not positioned above the main housing 100, so that the pump 130 and the light-emitting element are not in operation.

[0087] For this purpose, a placement sensing unit 170 is provided for sensing whether the upper housing 110 is placed on the upper part of the main housing 100.

[0088] If the placement sensor 170 detects that the upper housing 110 is placed on top of the main housing 100, power is supplied to operate the pump 130 and the light emitter. Conversely, if the placement sensor 170 detects that the upper housing 110 is not placed on top of the main housing 100, power supply is stopped, preventing the pump 130 and the light emitter from operating. In this case, the power supply to the pet water supply system 1 can be stopped only for the pump 130 and the light emitter, rather than the entire system.

[0089] The placement sensing unit 170 may include a magnet 171 and a magnet sensing unit 172 for sensing changes in magnetic flux according to the movement of the magnet 171.

[0090] The magnet 171 is attached to the bottom surface of the upper housing 110, and the magnet sensing unit 172 is attached to the main housing 100. If the upper housing 110 detaches from the main housing 100, the magnet sensing unit 172 senses the detachment of the magnet 171, and the control unit stops supplying power to the pump 130 and the light emitter. If the upper housing 110 is positioned on top of the main housing 100, the magnet sensing unit 172 senses the magnet 171, and the control unit supplies power to the pump 130 and the light emitter.

[0091] The magnet sensing unit 172 can be configured using an MR sensor that senses the change in magnetic field based on the movement of the magnet 171, or a reed switch that turns the magnet 171 on / off.

[0092] An ambient light 181 that emits light can be provided at the front of the main housing 100. The light emitted from the ambient light 181 can arouse the pet's curiosity, thereby guiding the pet to the pet water supply device 1 so that it can drink water.

[0093] Reference Figure 8The control method of the pet water supply device 1 is explained.

[0094] As a control mode for the pet water supply device 1, it can be set to a first mode in which the pump 130 runs continuously so that the water does not stop and continues to circulate, and a second mode in which the pump 130 repeatedly runs for a first set time period and stops for a second set time period.

[0095] The second mode can be implemented as multiple modes by varying the first and second set times.

[0096] If pump 130 is running, the water inside the water tank 150 flows into the inlet of pump 130 through pump inlet filter 133, and the water discharged through pump 130 outlet flows through outlet pipe 131 and then through discharge section 121 to the upper part of top plate 120.

[0097] In this case, a predetermined amount of water is contained in the discharge space 121a of the discharge section 121, thereby playing a buffering role to prevent water that continuously flows into the discharge space 121a from splashing into the upper space.

[0098] Water discharged from the discharge section 121 is prevented from flowing backward by the discharge section protrusion 132d and is guided to flow forward towards the water storage section 122.

[0099] Water discharged from the discharge section 121 flows through the flow section 123 to the water storage section 122. Preferably, the water discharged from the discharge section 121 can flow to the water storage section 122 on the upper surface of the top plate 120 with the widest possible area or the widest possible width.

[0100] The top plate 120 is configured such that its width widens from the side where the discharge portion 121 is formed to the side where the water storage portion 122 is formed. Furthermore, the top plate 120 may be configured to slope downwards from one side to the other, and a pair of protrusions 124 that protrude upwards for a relatively long distance in the width direction may be formed in the flow portion 123 of the top plate 120. Additionally, the upper surface of the top plate 120 may be surface-treated to increase its surface roughness. Due to this configuration, water flows on the upper surface of the top plate 120 in a manner that diffuses widely in the width direction.

[0101] Furthermore, the pump 130 can be controlled to operate at a first output during the initial stage of operation, and after operating at the first output, to operate at a second output lower than the first output if a set condition is met. In this case, the set condition can be a set time.

[0102] If controlled as described above, the system initially operates at a higher first output, causing a large amount of water to be discharged from the discharge section 121 and pass through the flow section 123, thus creating a wider water width. Subsequently, after a set time, even if the output of the pump 130 decreases to a second output, the wider water width can be maintained due to the shape and surface treatment of the top plate 120.

[0103] In addition, when the water flows over the protrusion 124, it rises like waves, which can arouse the pet's curiosity and make it drink the water.

[0104] Furthermore, the top plate 120 is configured to slope downwards towards the front and to be wider towards the front, thereby creating a structure in which the flow of water can be clearly seen when the pet looks from the front, thus arousing curiosity and enabling the pet to drink water.

[0105] Furthermore, since water flows with a large width on the upper surface of the top plate 120, the accumulation of impurities on the upper surface of the top plate 120 can be minimized.

[0106] If the water storage capacity is exceeded after the water is stored in the water storage section 122, the water overflows over the edge of the top plate 120. The water overflowing from the water storage section 122 flows through the gap between the edge of the top plate 120 and the inner side of the side wall 111b of the upper housing 110 to the upper surface of the main body 111 of the upper housing 110, and then through the filter sections 141 and 142.

[0107] Water filtered by the filter sections 141 and 142 is collected in the water tank 150 and then circulated by the pump 130.

[0108] Although the present invention has been described in detail with reference to preferred embodiments listed above, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of the claims, the detailed description of the present invention, and the accompanying drawings, and these modifications are all within the scope of the present invention.
