[0253] The upper part (250) is positioned above the lower part (210). The positioning of the upper part (250) can be maintained by the middle plate (280), the protrusion (242), and the bushing (290). The upper part (250) is positioned so as to be able to move up and down on the upper side of the lower part (210).

[0254] The middle plate (280) is positioned apart from the printed circuit board (246). Therefore, even when the upper part (250) moves up and down, the middle plate (280) does not come into contact with the printed circuit board (246).

[0255] The pressurizing portion (284) of the middle plate (280) is arranged to be in contact with the weight sensor (244). When a pet is placed on the upper side of the upper part (250), at least one of the plurality of pressurizing portions (284) can press the corresponding weight sensor (244). Accordingly, the weight of the pet placed on the upper side of the upper part (250) can be measured.

[0256] When force is applied to one side of the upper part (250), the upper part (250) in the area where the force is applied can move downward. At this time, the middle plate (280) arranged on one side also moves downward.

[0257] The air purifier (1) can perform air purification operation even when a pet is positioned on the seat device (200) by positioning the seat device (200) on the upper side of the main body (100).

[0258] Furthermore, by placing the resting area in a high space, we increased the possibility of pets entering the resting area. In particular, reflecting the characteristic of cats who like to climb to high places, we incorporated a space for cats to rest on top of the air purifier (1).

[0259] The height of the seat device (200) is similar to that of a bed, providing a resting space at eye level with the cat owner. This has the effect of enhancing the happiness and comfort of the pet.

[0260] According to the present disclosure, there is an advantage in that a single product simultaneously provides a resting space for pets and air purification functions, thereby eliminating the need for additional products.

[0261] In addition, reflecting the characteristics of cats that like to wrap themselves around the body and prefer warm spaces, the air purifier (1) provides a heating function using a heater (264).

[0262] Additionally, functions such as measuring a cat's weight and usage time are applied to the space, allowing the cat's daily life patterns to be naturally measured, and cat owners can utilize this information to manage their cat's health. The measured data can be checked and managed through the application.

[0263] The air purifier (1) features various functions, such as pet weight measurement, heating function, and usage time measurement, and can analyze the pet's condition and lifestyle patterns. Users can run the application on their mobile devices to check real-time weight measurement results, weight measurement history, and other information, and control the heating temperature.

FIG. 10B is an exploded perspective view of a heater assembly according to an embodiment of the present disclosure. FIG. 11 is a cross-sectional view of one side of a sheet device including a heater assembly according to an embodiment of the present disclosure.

[0265] In FIGS. 10a to 11, for convenience of explanation of the heater assembly (1000), the sheet (254) on the upper side of the heater assembly (1000) is shown with the sheet (254) removed.

[0266] Referring to FIGS. 10A to 11, the heater assembly (1000) can be fixed to the seat cover (266). The heater assembly (1000) can be placed in a space (267) formed internally by the seat device (200). The assembly efficiency can be improved by installing the assembled heater assembly (1000) itself to the seat cover (266).

[0267] A sheet (254) can be easily mounted on the upper side of the heater assembly (1000). In addition, the sheet (254) can be separated from the mounting plate (258) toward the upper side.

[0268] The sheet (254) includes a sensing projection (256) protruding downward from the lower surface.

[0269] The sheet (254) may include a plurality of apertures. The sensing protrusion (256) may be coupled to at least one of the apertures.

[0270] A center hole (260) that is open downward may be formed at the center of the mounting plate (258). A sensing projection (256) may be inserted into the center hole (260) formed in the mounting plate (258). In addition, a hole (265b) through which the sensing projection (256) passes may be formed at the center of the heater (264).

[0271] The seat cover (266) may have a shape that wraps around the perimeter of the seat (254) and the mounting plate (258). The seat cover (266) may form a space (267) above the seat (254).

[0272] The heater assembly (1000) is located on the lower side of the seat (254). The pet can rest on the upper side of the seat (254). When the heating function is used, the heater assembly (1000) can supply heat to the seat (254) from the lower side of the seat (254).

[0273] The mounting plate (258) may be made of a material with high thermal conductivity. For example, at least a portion of the mounting plate (258) may be made of metal. When the heater (264) is activated, the mounting plate (258) may rapidly heat up. However, heat is transferred to the pet through the seat (254). Accordingly, burns caused by rapid temperature increases can be prevented, and a comfortable environment with an appropriate temperature can be created.

[0274] The heater assembly (1000) may include a mounting plate (258) on which a sheet (254) is detachably disposed, a heater (264) disposed on the lower side of the mounting plate (258), and an annular middle plate (280) disposed on the lower side of the heater (264).

[0275] The mounting plate (258) may include a fastening projection (259) protruding downward. The fastening projection (259) may protrude downward from the lower surface of the mounting plate (258).

[0276] A fastening hole (265b) through which a fastening projection (259) passes may be formed in the heater (264). The number and position of the fastening holes (265b) may correspond to the number and position of the fastening projections (259).

[0277] A fastening hole (285) through which a fastening projection (259) passes may be formed in the middle plate (280). The number and position of the fastening holes (285) may correspond to the number and position of the fastening projections (259).

[0278] The fastening projection (259) can be connected to the fixed cap (1010) by penetrating the fastening hole (265b) of the heater (264) and the fastening hole (285) of the middle plate (280).

[0279] The mounting plate (258), heater (264), and middle plate (280) can be pre-assembled and then joined to the seat cover (266) as an integral assembly. At least a portion of the heater assembly (1000) can be joined to the seat cover (266).

[0280] For example, a middle plate (280) may be coupled to a seat cover (266). As described with reference to FIG. 7, the middle plate (280) may further include a connecting portion (288) and a pressing portion (284). The connecting portion (288) may be arranged to be fixed to the seat cover (266).

[0281] The pressurizing portion (284) of the middle plate (280) can be positioned to contact the upper side of the weight sensor (244) when the pet climbs onto the seat (254).

[0282] The air purifier (1) can detect whether a pet has climbed onto the seat device (200) through a weight sensor (244) and measure the pet's rest time.

[0283] In addition, the air purifier (1) can measure the heating function usage time by measuring the time the pet is on the seat (252) through the weight sensor (244) while the heating function is in operation.

[0284] Users can manage their pet's heating function usage time through the app. Furthermore, users can prevent low-temperature burns in their pets by adjusting the target temperature of the heating function based on the usage time.

[0285] In addition, the air purifier (1) can prevent pets from being exposed directly on the hot mounting plate (258) by providing a heating function only when the seat (254) is mounted.

[0286] The seat device (200) may include a confirmation sensor (262) that confirms when the seat (254) is mounted on the mounting plate (258).

[0287] FIG. 12 is a drawing for reference in a description of a method for checking whether a sheet is mounted according to an embodiment of the present disclosure, and is an enlarged view of the central portion where the detection protrusion (256) and the confirmation sensor (262) are located.

[0288] The confirmation sensor (262) is placed on the lower side of the mounting plate (258). The detection protrusion (256) can be inserted into a central hole (260) formed in the central portion of the mounting plate (258). One side of the central hole (260) can be open. The confirmation sensor (262) can be placed on the open side of the central hole (260).

[0289] When the sheet (254) is placed on the upper side of the mounting plate (258), the detection protrusion (256) can come into contact with one side of the confirmation sensor (262). Therefore, the confirmation sensor (262) can check whether the sheet (254) is placed or not by whether it comes into contact with the detection protrusion (256).

[0290] Alternatively, the confirmation sensor (262) may be a sensor that detects pressure. The confirmation sensor (262) can detect the pressure applied to the detection protrusion (256) and check whether the sheet (254) is positioned.

[0291] If the detection protrusion (256) and / or the confirmation sensor (262) are exposed to the outside, the heating function may malfunction if the pet presses on the exposed detection protrusion (256) or confirmation sensor (262).

[0292] In the present disclosure, the detection protrusion (256) is inserted into the central hole (260), and the confirmation sensor (262) is in contact with the detection protrusion (256) on the lower side of the sheet (254) and is not exposed to the outside. Therefore, an accident that may occur due to a pet accidentally activating the heating function in the absence of the sheet (254) can be prevented.

[0293] Meanwhile, depending on the material of the mounting plate (258), it may be difficult to form a central hole (260) in the center, or the manufacturing cost may increase significantly.

[0294] FIG. 13 is a drawing for reference in a description of a structure for providing a heating function according to one embodiment of the present disclosure, and FIG. 14 is a cross-sectional view of one side of a sheet device to which the structure for providing a heating function of FIG. 13 is applied.

[0295] Referring to FIGS. 13 and 14, the mounting plate (258) may include a first plate (1310) positioned above the heater (264) and a second plate (1320) surrounding the first plate (1310).

[0296] A heater (264) may be placed on the lower side of the first plate (1310). The first plate (1310) may be made of a material with high thermal conductivity. For example, the first plate (1310) may be made of aluminum.

[0297] The second plate (1320) can be combined with a heater (264), a middle plate (1330), and a fixed cap (1340). A confirmation sensor (1350) can be placed on the lower side of the second plate (1320).

[0298] The air purifier (1) can determine whether the sheet (254) is mounted based on whether there is contact with the upper side of the confirmation sensor (1350). Alternatively, the air purifier (1) can determine whether the sheet (254) is mounted based on pressure data applied from the upper side of the confirmation sensor (1350).

[0299] When mounting the sheet (254), a protrusion (not shown) protruding downward from the lower surface of the second plate (1320) may be formed to facilitate contact with the confirmation sensor (1350) or to increase the pressure applied to the confirmation sensor (1350).

[0300] FIGS. 15 to 17 are drawings for reference in the description of a structure for providing a heating function and a cooling function according to one embodiment of the present disclosure.

[0301]

[0302] *Referring to FIGS. 15 to 17, the seat device (200) may include a seat cover (266) and a peltier assembly (1500) fixed to the seat cover (266). The peltier assembly (1500) may be placed in a space (267) formed internally by the seat device (200).

[0303] A sheet (254) can be mounted on the upper side of the Peltier assembly (1500).

[0304] A Peltier assembly (1500) may include a mounting plate (1510) on which a sheet (254) is detachably disposed, a Peltier element (1520) disposed on the lower side of the mounting plate (1510), a transfer plate (1525) supporting the Peltier element (1520), and an annular middle plate (1530) disposed on the lower side of the transfer plate (1525).

[0305] The transfer plate (1525) can be combined with other components in the same manner as the embodiment described with reference to FIG. 10b.

[0306] For example, a fastening hole (1521a) may be formed in the transfer plate (1525). In addition, a fastening hole (1535) may also be formed in the middle plate (280). A fastening protrusion (not shown) protruding downward is formed in the settling plate (1510), and the fastening protrusion may pass through the fastening hole (1521a) of the transfer plate (1525) and the fastening hole (1535) of the middle plate (280) and then be coupled to the fixing cap (1540).

[0307] Meanwhile, the sheet (254) includes a sensing protrusion (1550) protruding downward from the lower surface.

[0308] The sheet (254) may include a plurality of apertures. The sensing protrusion (1550) may be coupled to at least one of the apertures.

[0309] A center hole (1515) that is open downward may be formed at the center of the mounting plate (1510). A sensing projection (1550) may be inserted into the center hole (1515) formed in the mounting plate (1510). In addition, a hole (1521b) through which the sensing projection (1550) passes may be formed at the center of the transmission plate (1525).

[0310] The seat cover (266) may have a shape that wraps around the perimeter of the seat (254) and the mounting plate (1510). The seat cover (266) may form a space (267) above the seat (254).

[0311] The Peltier assembly (1500) is located on the lower side of the seat (254). The pet can rest on the upper side of the seat (254).

[0312] The user can operate the Peltier element (1520) to use the heating function in winter and the cooling function in summer.

[0313] Alternatively, users can use the heating and cooling functions depending on the environment their pet is in.

[0314] For example, the seat device (200) can provide a heating function when the indoor environment temperature where the cat is present is low. Additionally, the seat device (200) can provide a cooling function when the indoor environment temperature where the cat is present is high.

[0315] When using the heating function, the peltier assembly (1500) can warm the sheet (254) from the lower side of the sheet (254). When using the cooling function, the peltier assembly (1500) can cool the sheet (254) from the lower side of the sheet (254).

[0316] The mounting plate (1510) may be made of a material with high thermal conductivity. For example, at least a portion of the mounting plate (1510) may be made of metal. When the Peltier element (1520) is activated, the mounting plate (1510) may rapidly heat up or cool down. However, heat is transferred to the pet through the seat (254). Accordingly, a comfortable environment with an appropriate temperature can be created.

[0317] The air purifier (1) can measure the heating function usage time and the cooling function usage time by measuring the time the pet is on the seat (252) through the weight sensor (244) while the heating function or cooling function is in operation.

[0318] Users can manage their pet's heating or cooling function usage time through the application.

[0319] In addition, the air purifier (1) can prevent pets from being exposed directly on the hot or cold mounting plate (258) by providing a heating function or a cooling function only when the seat (254) is mounted.

[0320] The seat device (200) may include a confirmation sensor (1560) that confirms when the seat (254) is mounted on the mounting plate (1510).

[0321] The confirmation sensor (1560) is placed on the lower side of the mounting plate (1510). The detection protrusion (1550) can be inserted into a central hole (1515) formed in the central portion of the mounting plate (1510). One side of the central hole (260) can be open. The confirmation sensor (1560) can be placed on the open side of the central hole (1515).

[0322] When the sheet (254) is placed on the upper side of the mounting plate (1510), the detection protrusion (1550) can come into contact with one side of the confirmation sensor (1560). Therefore, the confirmation sensor (1560) can check whether the sheet (254) is placed or not by whether it comes into contact with the detection protrusion (1550).

[0323] Alternatively, the confirmation sensor (1560) may be a sensor that detects pressure. The confirmation sensor (1560) can detect the pressure applied to the detection protrusion (1550) and check whether the sheet (254) is positioned.

[0324] Although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and it goes without saying that various modifications can be made by a person having ordinary skill in the art to which the present disclosure pertains without departing from the gist of the present disclosure as claimed in the claims.
