By forming a curved surface on the drain tank (30), the space inside the housing (70) can be efficiently used to store a larger amount of drained water in the drain tank body (31).

[0091] The drain tank body (31) may be formed with a second support portion (311) that protrudes downward from a portion of the lower portion of the drain tank body (31). The cross-section of the second support portion (311) may be smaller than the cross-section of the drain tank body (31). The bottom surface of the second support portion (311) may be parallel to the cradle top plate (41).

[0092] A handle portion (not shown) may be formed on the drain tank cover (32). As the handle portion is formed on the drain tank cover (32), the user can easily separate the drain tank (30) upward from the housing (70).

[0093] A drain hole (321) may be formed in the drain tank cover (32). Water may be discharged from the drain line (60) to the drain tank body (31) through the drain hole (321). A fitting may be arranged in the drain hole (321). The fitting may be referred to as a second fitting (323). The drain line (60) may be connected to the second fitting (323). One end of the second fitting (323) may be connected to a third drain line (63).

[0094] The second fitting part (323) may be combined with the drain tank cover (32) in a separate configuration from the drain tank cover (32). When combined with the drain tank cover (32) in a separate configuration, a gasket (322) may be placed between the second fitting part (323) and the drain hole (321).

[0095] In another embodiment of the present invention, the third drain line (63) can be directly inserted into a drain hole (321) formed in a drain tank cover (32).

[0096] In another embodiment of the present invention, a fitting portion (not shown) formed around the drain hole (321) and protruding upward from the upper surface of the drain tank cover (32) may be formed integrally with the drain tank cover (32).

[0098] A Wi-Fi module (92) for communicating with a user may be placed in the second space (82). The Wi-Fi module (92) may be attached to a mounting plate. The Wi-Fi module (92) may be electrically connected to a controller (91). In another embodiment of the present invention, the controller (91) may include a Wi-Fi module (92).

[0099] Referring to FIGS. 2, 6, and 10, a shielding plate (80) may be placed inside the housing (70) to divide a first space (81) in which a water supply tank (20) and a drain tank (30) are placed, and a second space (82) in which a pump is placed.

[0100] Referring to FIGS. 12 and 13, the cradle (40) may include an upper plate (41) and a lower plate (49). A space (400) may be formed between the upper plate (41) and the lower plate (49) to allow a water supply line (50) and a drainage line (60) to pass therethrough. A power board (401) that supplies power to a controller (91) may be placed in the space (400) of the cradle. The power board (401) may supply power to a lighting LED (not shown), an LED (not shown) of a quantity display unit (100), a water supply pump (500), a drainage pump (600), and a Wi-Fi module (92) described below.

[0101] The shielding plate (80) can be fixed by screwing the shielding plate (80) connecting portion (801) into the shielding plate (80) connecting hole (433) formed on the cradle top plate (41).

[0102] Referring to Fig. 6, the shielding plate (80) may be formed with side support portions (802) that contact the inner surface of the housing (70) on both sides extending in the vertical direction. By having the side support portions contact the inner surface of the housing (70), the shaking of the shielding plate (80) can be prevented.

[0103] Referring to FIGS. 2, 6, 10, and 11, an upwardly protruding annular rim (110) may be arranged on the surface of the upper plate (41) of the cradle. The annular rim (110) may be formed with two concentric circles having different diameters in cross-section, a first annular rim part (110a) having a larger cross-section and a second annular rim part (112) having a smaller cross-section, and an annular rim horizontal portion (113) connecting the first annular rim part (110a) and the second annular rim part (112) may be formed.

[0104] On the upper surface of the annular rim horizontal portion (113), an annular groove (113a) may be formed that is concave downwardly adjacent to the annular rim first part (110a), and on the outer side of the annular groove (113a), a protruding rib that protrudes upward from the upper surface of the annular rim horizontal portion (113) may be formed.

[0105] The annular rim (110) may have an annular space (110c) formed therein. That is, the annular space (110c), which is an empty space, may be formed between the annular rim first part (110a), the annular rim second part (112), and the annular rim horizontal part (113). An annular protrusion (432) protruding upward is formed on the main body mounting portion (43) of the cradle upper plate (41), and the annular rim (110) may be fixed to the cradle upper plate (41) by inserting the protrusion (432) into the annular space (110c). In another embodiment of the present invention, the lower portion of the annular rim first part (110a) may be fitted into a cradle dent portion (431) formed on the cradle upper plate (41), thereby being fixed to the cradle upper plate (41).

[0106] An LED for lighting may be placed in the annular space (110c). The LED for lighting may be provided with a function to display the amount of water stored in the water supply tank (20) or drain tank (30) in color.

[0107] A hole (112a) through which a cable connected to an LED for lighting can pass may be formed in the second part of the annular rim (112).

[0108] The housing (70) may include a side cover (71) having a cylindrical shape with an empty interior, and a top cover (72) covering the upper surface of the side cover (71).

[0109] A transparent window (73) through which the quantity display unit (100) is visible may be formed on the side cover (71).

[0110] The lower part of the side cover (71) of the housing (70) may be formed with a circular downward protrusion (711). The downward protrusion (711) may include a second downward protrusion (7112) extending from the outer circumferential surface of the side cover (71) and a first downward protrusion (7111) formed inwardly spaced from the second downward protrusion (7112).

[0111] An upwardly protruding annular rim (110) is arranged on the surface of the upper plate (41) of the cradle, and an annular downward protrusion (711) formed on the lower part of the housing (70) can be inserted into the inner or outer side of the annular rim (110).

[0112] The second downward protrusion (7112) may be formed with a downward protrusion (7112a) protruding downward, and the downward protrusion (7112a) may be inserted into an annular groove (113a) formed in the annular rim horizontal portion (113). The first downward protrusion (7111) may be inserted into the inside of the annular rim (110).

[0113] Referring to FIGS. 11 and 13, a housing (70) coupling protrusion (48) can be formed on the upper plate (41) of the cradle, and the lower end of the second downward protrusion (7112) can be inserted between the housing (70) coupling protrusion (48) and the cradle step surface (437) formed on the cradle upper plate (41) described later.

[0114] Referring to FIGS. 10 to 12, a support assembly mounting portion (42) on which a support (11) assembly is placed can be formed on the upper plate (41) of the cradle. A main body mounting portion (43) on which a water supply / drain tank (30), annular rim (110), a housing (70), etc. are mounted can be formed on the upper plate (41) of the cradle.

[0115] The supporting assembly mounting portion (42) may have an opening (421) formed therein, and a protrusion (423) protruding upward from the upper plate (41) may be formed around the opening (421). A first protrusion (424a) and a second protrusion (424b) protruding upward from the upper plate (41) may be formed around the protrusion (423).

[0116] The main body mounting portion (43) may be formed with a cradle dent portion (431) that is recessed downward from the upper side of the upper plate (41). A cradle step surface (437) may be formed on the edge of the cradle dent portion (431). A first hole (431a) through which a water supply line (50) passes, a second hole (431b) through which a drainage line (60) passes, and a third hole (431c) through which a cable connected to the power board (401) passes may be formed in the cradle dent portion (431). A shielding plate (80) joining hole (433) to which a shielding plate (80) joining portion (801) can be joined may be formed in the cradle dent portion (431). A plurality of shielding plate (80) joining holes (433) may be formed. A load cell (44) for measuring the weight of the drain tank (30) can be placed in the cradle dent section (431). (Hereinafter, 'load cell (44)' means 'first load cell (44)')

[0117] Referring to FIGS. 13 and 14, the load cell (44) can be coupled to the first mount portion (434) protruding upward from the cradle dent portion (431) formed on the main body mounting portion (43). The load cell (44) is positioned apart from the load cell second part (442), which is the portion coupled to the first mount portion (434), and the load cell first part (441), which is the portion to which a load is applied, and a support plate (45) (hereinafter, “support plate” means “first support plate”) can be placed.

[0118] The support plate (45) may have a mounting portion (451) formed on the upper surface on which the drain tank (30) is mounted, an upper edge (452) protruding upward from the edge of the mounting portion (451) may be formed, and a lower edge (453) protruding downward from the edge of the mounting portion (451) may be formed. The support plate (45) may have a protruding support portion (454) formed on the rear surface of the central portion of the mounting portion (451) protruding downward. The load cell first part (441) may be coupled to the protruding support portion (454) of the support plate (45).

[0119] Since the protruding support member (454) coupled with the load cell first part (441) has a step lower than the back surface of the support plate (45), the load of the support plate (45) can be vertically transmitted only to the load cell first part (441).

[0120] Since the first mount portion (434) to which the second load cell part (442) is coupled has a step upward from the cradle dent portion (431) of the main body mounting portion (43), the first load cell part (441) does not come into contact with the cradle dent portion (431), thereby preventing errors in the load cell (44) measurement value that measures weight due to bending of the load cell (44).

[0121] A second support member (311) formed on the lower side of the drain tank body (31) can be mounted on a mounting member (451) of a support plate (45). The second support member (311) can be inserted into the upper edge (452) of the support plate (45). The outer circumference of the second support member (311) can be in contact with the upper edge (452).

[0122] When the drain tank (30) is placed on the support plate (45), the deflection of the load cell (44) coupled with the support plate (45) varies depending on the weight of the water contained within the drain tank (30), and the weight of the water contained within the drain tank (30) or the amount of change in the weight can be measured through the difference in the degree of deflection. The measured weight of the water or the amount of change in the weight of the water can be electrically connected to the controller (91) via a cable connected to the load cell (44).

[0123] A second load cell (46) for measuring the weight of the water supply tank (20) may be placed in the cradle dent section (431). The second load cell (46), the second support plate (47), and the second mount section (436) for measuring the weight of the water supply tank (20) are the same as the load cell (44), the support plate (45), and the first mount section (434) for measuring the weight of the drain tank (30), and therefore, a description thereof will be omitted.

[0124] Referring to FIGS. 6 and 15, a filter housing (65) having a built-in filter (66) may be connected to the drain line (60). The filter housing (65) may include a hollow first filter housing portion (651) formed at an inlet end (6511) through which drainage flows in, and a hollow second filter housing portion (652) formed at a discharge end (6521) through which drainage is discharged and detachably coupled to the first filter housing portion (651). The filter (66) may be disposed inside at least one of the first filter housing portion (651) and the second filter housing portion (652).

[0125] The first filter housing part (651) may have screw threads formed on the inner surface. The second filter housing part (652) may have a connecting part formed on the other end opposite the discharge end (6521), in which a portion of the outer surface is cut off and screw threads are formed on the cut off portion. The screw threads formed on the inner surface of the first filter housing part (651) and the connecting part of the second filter housing part (652) may be screw-connected. A gasket (655) may be included between the connecting part of the first filter housing part (6512) and the connecting part of the second filter housing part (6522).

[0126] The inlet end (6511) of the first filter housing part (651) can be connected to the first drain line (61) connected from the connecting pipe (56). The discharge end (6521) of the second filter housing part (652) can be connected to the second drain line (62) connected to the drain pump (600).

[0127] The filter housing (65) can be separated and combined into a first filter housing part (651) and a second filter housing part (652), and as a filter (66) is inserted therein, the user can easily replace the filter (66).

[0128] The controller (91) can intermittently control the operation or stop of the water supply pump (500) and the drain pump (600). The user can directly set the time interval at which the water supply pump (500) and the drain pump (600) are operated. When the water supply pump (500) and the drain pump (600) are intermittently operated, the drain pump (600) may be operated first, and then the water supply pump (500) may be operated when the operation of the drain pump (600) is stopped.

[0129] The controller (91) can control the water supply pump to operate when the water level in the basin (11) is below a first set value, and to stop the water supply pump (500) when the water level reaches a second set value. A sensor (not shown) capable of measuring the water level in the basin (11) can be attached to the basin (11). The sensor can be an optical level switch sensor. When the optical level switch sensor touches the surface with liquid, the reflection angle of the light emitted from the LED built into the sensor changes, and a difference in the amount of light detected by the light receiving unit built into the sensor occurs, thereby detecting whether the surface is touched by liquid. The sensor can be positioned on the surface of the basin at a certain height.

[0130] The controller (91) can receive a command from a user and control the operation of the drain pump (600). Methods for receiving a command from a user may include a method in which the user directly touches the drain button formed on the top cover (72) of the housing (70), or a method in which the user transmits a signal to the WiFi module (92) built into the controller (91) using WiFi communication of a mobile device.

[0131] When the drain pump (600) is in operation, if the weight increase of the drain tank (30) measured by the load cell (44) for a certain period of time is below a predetermined value, a signal can be transmitted to notify the user of this, or a warning sign can be displayed on the pet watering device (1).

[0132] The remaining residue in the water drained from the drain (11) may accumulate in the filter (66) inside the filter housing (65) connected to the drain line (60), and as the residue accumulates, the amount of drained water discharged through the filter (66) per hour decreases. Therefore, when the weight increase of the drain tank (30) measured by the load cell (44) for a certain period of time is below a predetermined value, a signal is transmitted to notify the user of this, or a warning sign is displayed on the pet watering device (1), thereby allowing the user to check when to replace the filter (66).

[0133] The above preset values ​​can be set directly by the user. Users can set the preset values ​​via Wi-Fi communication.

[0134] When the weight increase of the drain tank (30) measured by the load cell (44) is below a predetermined value, the controller can transmit a signal to notify the user of this, or when a warning sign is displayed on the pet watering device (1), the operation of the drain pump (600) can be controlled to stop.

[0135] If the weight increase of the drain tank (30) is less than a predetermined value, a lot of debris gets caught in the filter (66), which has the same effect as a decrease in the cross-sectional area of ​​the drain pipe. That is, the amount of drainage discharged to the drain line (60) per hour decreases, and the drain pump may overheat. Therefore, if the weight increase of the drain tank (30) measured by the load cell (44) over a predetermined period of time is less than a predetermined value, the operation of the drain pump (600) is stopped, thereby preventing overheating of the drain pump (600) and a fire.

[0136] If the weight increase of the drain tank (30) converges to 0 for a certain period of time, the controller (91) may notify the user of this, or the operation of the drain pump (600) may be stopped without displaying a warning sign.

[0137] A pet watering device (1) may include: a basin (11) for storing water for a pet to drink; a water supply tank (20) for storing water supplied to the basin (11); a drain tank (30) for storing water discharged from the basin (11); a water supply line (50) connected to the water supply tank (20); a drain line (60) connected to the drain tank (30); at least one pump (500, 600) for supplying water from the water supply tank (20) to the basin (11) through the water supply line (50) or for draining water from the basin (11) to the drain tank (30) through the drain line (60); and a controller (91) for controlling the operation of the pump.

[0138] The above pump (500, 600) may include: a water supply pump (500) that supplies water from the water supply tank (20) to the water tank (11) through the water supply line (50); and a drain pump (600) that drains water from the water tank (11) to the drain tank (30) through the drain line (60).

[0139] The above water supply line (50) and the above drainage line (60) include a joining line (55) that joins them together, and the joining line (55) can be connected to the first hole (114) formed in the water tank (11).
