Description

air purifier

[0001] The present disclosure relates to an air purifier, and more particularly, to an air purifier having a sheet device disposed on the upper side for discharging purified air.

[0002] An air purifier is a device that creates air flow and filters the flowing air to increase the cleanliness of the air within a certain space.

[0003] The air purifier may have a configuration in which an inlet is formed on one side, an outlet is formed on the other side, and a filter is placed inside.

[0004] The air purifier can have an outlet formed at the top so that the filtered air is not delivered directly to the user.

[0005] Korean registered patent KR 10-2600644 B1 discloses an air purifier having an outlet formed at the top.

[0006] However, in households where pets such as cats live in the area where the air purifier is installed, there is a risk that the pets will climb up to the upper area of ​​the air purifier and cause the air purifier to tip over.

[0007] Additionally, if a pet is located above where the outlet is formed, it may obstruct the flow of clean air emitted by the air purifier.

[0008] Additionally, there is a problem that pets may become stressed due to vibrations or noise caused by the operation of the air purifier.

[0009] Meanwhile, for pets who prefer warm environments, a heating function can be applied to the resting area. However, pets have sensitive skin and are prone to low-temperature burns.

[0010] Figure 18 illustrates the results of a burn severity test according to exposure temperature in rats disclosed in "Experimental studies of moderate temperature burns (T Suzuki 1, T Hirayama, K Aihara, Y Hirohata)". Score 1 indicates a level where vasodilation occurs and there is a small amount of inflammatory cell infiltration around the blood vessels. Score 2 indicates a level where necrosis occurs in the epidermal layer and there is a lot of inflammatory cell infiltration around the blood vessels. Score 3 indicates a level where collagen fibers are degenerated only in the upper part of the dermis. Score 4 indicates a level where collagen fibers are degenerated in the middle part of the dermis. Score 5 indicates a level where collagen fibers are degenerated deep into the dermis.

[0011] The skin of pets like dogs and cats is more delicate than that of humans or rats. Pets can suffer low-temperature burns if exposed to temperatures even slightly higher than body temperature for extended periods. Furthermore, pets' fur makes early detection of burns difficult.

[0012] The purpose of the present disclosure is to provide an air purifier that creates a space where a pet can rest without interfering with the function of the air purifier.

[0013] The purpose of the present disclosure is to provide an air purifier that creates a more comfortable resting space with a heating function.

[0014] The purpose of the present disclosure is to provide an air purifier that can prevent low-temperature burns even when a pet uses the heating function for a long time.

[0015] The purpose of the present disclosure is to provide an air purifier capable of controlling temperature by taking into account the characteristics of a pet, such as its type, age, and size.

[0016] The purpose of the present disclosure is to provide an air purifier having a structure that minimizes external noise in a resting space for a pet placed on one side of the air purifier.

[0017] The purpose of the present disclosure is to provide an air purifier that minimizes air flow toward a pet resting area located on one side of the air purifier.

[0018] The purpose of the present disclosure is to provide an air purifier having various functions such as measuring the weight of a pet, a heating function, and measuring the usage time, and capable of understanding the condition and lifestyle patterns of a pet.

[0019] The tasks of the present disclosure are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0020] An air purifier according to an embodiment of the present disclosure comprises a main body having an inlet formed on a peripheral surface and an outlet formed above the inlet, and a seat device fixedly disposed on the main body or separated from the main body, thereby forming a space where a pet can rest without interfering with the function of the air purifier.

[0021] An air purifier according to an embodiment of the present disclosure can prevent low-temperature burns by having an upper sheet device equipped with a heater and sensors and preemptively controlling the target temperature of the heater based on the amount of temperature change.

[0022] An air purifier according to one embodiment of the present disclosure comprises a main body having an inlet formed on a peripheral surface and an outlet formed above the inlet; and a seat device fixedly disposed on the main body or separated from the main body, wherein the seat device includes a heater, one or more temperature sensors, and a weight sensor for detecting the presence of a pet, and a target temperature of the heater is controlled based on a time interval from a point in time when the pet is detected by the weight sensor to a point in time when a change in temperature detected by the temperature sensor reaches a reference change temperature value.

[0023] The above sheet device includes a mounting plate disposed on the upper side of the heater, and a sheet disposed on the upper side of the mounting plate.

[0024] The above temperature sensor is a temperature sensor attached to the above mounting plate or the above sheet.

[0025] Alternatively, the temperature sensor is a heater temperature sensor attached to the heater.

[0026] If the first value based on the above arrival time is greater than or equal to the first reference value, the target temperature is lowered by the first temperature.

[0027] If the first value is greater than or equal to a second reference value that is smaller than the first reference value and less than the first reference value, the target temperature is lowered by a second temperature that is smaller than the first temperature.

[0028] If the first value is less than the second reference value, the target temperature is maintained.

[0029] The above first value is the arrival time or the ratio of the arrival time and the preset reference time.

[0030] The amount of change in the above target temperature is proportional to the arrival time.

[0031] In recognition mode, the heater operates when the target temperature is higher than the current temperature detected by the temperature sensor and the pet is detected by the weight sensor.

[0032] If the current temperature detected by the temperature sensor is greater than the sum of the temperature at the time the heater operates and the reference change temperature value, the target temperature of the heater is controlled based on the arrival time.

[0033] An air purifier according to one embodiment of the present disclosure further includes a memory.

[0034] In the above memory, the temperature value detected by the temperature sensor at the time when the pet is detected by the weight sensor and the heater is operating is stored.

[0035] In the constant mode, the heater performs a heating operation in response to the target temperature. In the constant mode, if the target temperature is higher than the current temperature detected by the temperature sensor and the pet is detected by the weight sensor, the temperature value detected by the temperature sensor at the time the pet is detected by the weight sensor is stored in the memory.

[0036] An air purifier according to one embodiment of the present disclosure further includes a communication unit that receives data related to the companion animal.

[0037] In response to the data related to the above companion animal, the amount of change in the target temperature is adjusted.

[0038] If the hair length of the pet is less than the standard value, the change in the target temperature is increased from the default value.

[0039] If the hair length of the pet is greater than the standard value, the change in the target temperature is reduced from the default value.

[0260] 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).

[0261] 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.

[0262] 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.

[0263] FIG. 10 is a drawing for reference in the description of the heating function of a sheet device according to one embodiment of the present disclosure.

[0264] Referring to Fig. 10, a seat portion (252) is placed in a space (267) formed internally by the seat device (200). As described above, a heater (264) is placed on the lower side of the seat portion (252) to provide a heating function to a pet sitting on the seat portion (252).

[0265] The seat portion (252) includes a mounting plate (258) and a seat (254). The mounting plate (258) is positioned above the heater (264), and the seat (254) is positioned above the mounting plate (258). When the heater (264) performs a heating operation, the mounting plate (258) is heated, and the temperature of the mounting plate (258) can be transmitted to the companion animal through the seat (254).

[0266] The heater (264) and the mounting plate (258) have a disc shape and can evenly supply heat to at least a portion of the area (Z1) of the sheet portion (252). The area providing the heating function can be closed depending on the shape and size of the heater (264) and the mounting plate (258). For example, a larger disc-shaped heater (264) and mounting plate (258) can be used to transmit heat to the entire area (Z1, Z2) of the upper surface of the sheet portion (252).

[0267] A user can operate the operating switch for the heating function to turn on the heating function, and adjust the heating level in response to the number of times the operating switch is operated. For example, any one of the multiple switches (248a, 248b, 248c) can be set as the operating switch for the heating function.

[0268] A target temperature can be set for each heating stage. The control unit (see 1340 of FIG. 13) can control the heater (264) to a target temperature corresponding to the heating stage selected by the user. For example, if stages 1 and 2 are provided, heating stage 1 can be set to a low temperature mode with a target temperature of 34 degrees, and heating stage 2 can be set to a high temperature mode with a target temperature of 37 degrees.

[0269] Alternatively, the user can control the air purifier (1) by running a home appliance management application on a mobile terminal.

[0270] FIG. 11 is a drawing for reference in an explanation of temperature control using a mobile terminal according to an embodiment of the present disclosure.

[0271] The user can check and control the status of the air purifier (1) by running an application (e.g. ThinQ) or accessing a specific website through a mobile terminal (1100).

[0272] Additionally, the user can control the heating function of the air purifier (1) through the mobile terminal (1100). For example, the operating mode and target temperature of the heating function can be set.

[0273] Figure 11 illustrates a user interface (UI) screen (1110) of an application running on a mobile terminal (1100).

[0274] The UI screen (1110) may include items related to the pet's weight measurement function and items related to the heating function. Items related to the heating function may include items for setting the operating mode of the heating function and items for setting the target temperature of the heating function.

[0275] For example, an item that can set the target temperature of the heating function can be provided so that heating level 1 or heating level 2 can be selected, or the target temperature can be selected directly.

[0276] For example, the operating mode of the heating function may include a constant mode and a recognition mode. The constant mode is a mode in which the heating function is provided according to the set target temperature when the heating function is turned on through a switch (248a, 248b, 248c) or an application.

[0277] The recognition mode is a mode that provides a heating function only when a pet is detected by the weight sensor (244), and provides a heating function from the moment the pet gets on the seat device (200). Fig. 11 illustrates an example of setting the recognition mode on a pop-up screen (1120) when an item that can set the operation mode of the heating function is selected.

[0278] Users can enter pet-related information through the home appliance management application. For example, users can enter their pet's species and characteristics.

[0279] The information entered by the user is transmitted to the air purifier (1) so that it can provide services appropriate for the pet.

[0280] For example, a user can enter the type of pet, such as a dog or cat, and also enter a detailed breed of the pet (e.g., Siberian Husky, Chihuahua, Persian cat, Siamese cat).

[0281] Additionally, users can enter detailed characteristics such as the size of their pet and the length of its fur (long or short hair).

[0282] FIG. 12a and FIG. 12b are drawings for reference in the description of the temperature control of the heating function of the sheet device according to one embodiment of the present disclosure.

[0283] Figure 12a shows the heater control temperature and the detected temperature values ​​(C-1, C-2) over time when the heater (264) is in operation. Figure 12b shows the temperature measurement points C-1, C-2.

[0284] Figure 12a shows the temperature values ​​measured at points C-1 and C-2, respectively, when a cat is at point C-2 of Figure 12b. Point C-1 is a point not affected by the cat's body temperature, and point C-2 is a point affected by the cat's body temperature.

[0285] A cat's body temperature is about 38 to 39 degrees, and a temperature slightly higher than the cat's body temperature, 40 degrees, can be the standard temperature for low-temperature burns.

[0286] However, if the heating function is provided without considering the pet's body temperature, low-temperature burns may occur even if the heater (264) is operated so as not to exceed the burn risk temperature standard.

[0287] Therefore, in the present disclosure, low-temperature burns can be prevented by preemptively controlling the heater temperature by estimating the influence of the pet's body temperature and environmental temperature.

[0288] FIG. 13 is a block diagram of an air purifier according to an embodiment of the present disclosure.

[0289] Referring to FIG. 13, an air purifier according to an embodiment of the present disclosure may include a control unit (1340) and a fan drive unit (1380) that drives a fan (140) according to the control of the control unit (1340).

[0290] At least some of the internal blocks of the air purifier illustrated in Fig. 13, such as the control unit (1340) and the fan drive unit (1380), may be placed inside the main body (100). For example, the control unit (1340) may be mounted on a printed circuit board (123) placed in a space formed by the lower housing (114) placed on the upper side of the base (110).

[0291] A fan (140) is installed inside the main body (100) to control the flow of indoor air that is purified while passing through a filter (101) and then discharged into the indoor space. The fan (140) can be rotatably arranged between the inlet (106) and the outlet (112) to form an air flow from the inlet (106) to the outlet (112).

[0292] The fan motor (148) rotates the fan (140) according to a control signal received from the fan driving unit (1380). The rotation of the fan (140) is controlled by the fan driving unit (1380), and the operation of the fan driving unit (1380) is controlled by the control unit (1340). The fan driving unit (1380) may be equipped with a power conversion device such as an inverter to operate the fan motor (148).

[0293] The filter (101) removes foreign substances in the air flowing into the inlet (106). The filter (101) may include a pre-filter that filters foreign substances in the air, a HEPA filter that collects pollutants in the air, a deodorizing filter that removes odors in the air, etc. The pre-filter has a grill formed to primarily filter foreign substances in the air being sucked in. The HEPA filter collects pollutants in the sucked in air, and the deodorizing filter can remove odors in the sucked in air.

[0294] Meanwhile, the air purifier may include a memory (1330), a sensing unit (1350), a communication unit (1370), etc.

[0295] The memory (1330) may store data for controlling the operation of the air purifier, data detected or measured through the sensing unit (1350) during operation, and data received through the communication unit (1370). Meanwhile, the air purifier may include a buffer for temporarily storing data, and the buffer may be included in the control unit (1340) or the memory (1330).

[0296] The control unit (1340) can process various data received through the communication unit (1370) to update the memory (1145). For example, if the data input through the communication unit (1370) is update data for a driving program pre-stored in the memory (1330), the memory (1330) can be updated using this, and if the input data is a new driving program, the memory (1330) can be additionally stored therein.

[0297] The sensing unit (1350) can measure the level of air pollution or sense the operating status of the air purifier by including one or more sensors.

[0298] The control unit (1340) can control the flow of data input or output to the air purifier and generate and apply a control command based on data input from the sensing unit (1350).

[0299] Meanwhile, the air purifier can communicate with other devices such as servers, home appliances, and terminals through the communication unit (1370) to transmit and receive data.

[0300] The input unit (1310) can receive various user commands related to the operation of the air purifier and transmit a control signal corresponding to the input command to the control unit (1340). The input unit (1310) can include a touch pad, physical buttons, etc.

[0301] The output unit (1320) may be equipped with a display device such as a display (not shown) or a light emitting diode (LED) (not shown). For example, the output unit (1320) may display information such as the operating status of the air purifier, the occurrence of an error, the indoor temperature, and the target temperature.

[0302] The output unit (1320) may be equipped with an audio device such as a speaker (not shown) or a buzzer (not shown). For example, the output unit (1320) may output a sound effect regarding the operating status of the air purifier and may output a predetermined warning sound when an error occurs.

[0303] The control unit (1340) may be connected to each component of the air purifier. For example, the control unit (1340) may transmit and / or receive signals between each component of the air purifier and control the overall operation of each component.

[0304] The control unit (1340) may include at least one processor, and may control the overall operation of the air purifier using the processor included therein. Here, the processor may be a general processor, such as a central processing unit (CPU). Of course, the processor may also be a dedicated device, such as an ASIC, or another hardware-based processor.

[0305] Meanwhile, the control unit (1340) can control the overall operation of the air purifier and control a series of air purification processes such as intake of outside air and discharge of purified air.

[0306] The control unit (1340) can perform an air purification process according to a preset algorithm, and the fan drive unit (1380) can drive the fan (140) according to the control of the control unit (1340). The fan motor (148) is operated by a control signal sent from the fan drive unit (1380). The fan drive unit (1380) can control the rotation speed and direction of the fan (140) based on the control signal generated to improve air characteristics.

[0307] When the fan driver (1380) drives the fan (140) by rotating the fan motor (148), external air can be sucked into the air purifier through the inlet (106). The sucked air can be purified while passing through the filter (101) and then discharged to the outside through the outlet (112).

[0308] Meanwhile, the air purifier may be equipped with a temperature control function for pets. For example, a heater (264) is provided within the seat device (200). The control unit (1340) can operate the heater (264) to provide a heating function for pets positioned on the seat device (200).

[0309] The control unit (1340) can receive sensing data of the weight sensor (244) from the printed circuit board (246) of the seat device (200) and determine whether the pet is in the seat device (200). The control unit (1340) can control the fan (140) and the heater (264) based on whether the pet is in the seat device (200).

[0310] Additionally, one or more temperature sensors (not shown) may be placed in the sheet device (200), and the printed circuit board (246) may transmit sensing data of the temperature sensor to the control unit (1340).

[0311] The temperature sensor may include a temperature sensor attached to the mounting plate (258) and / or the sheet (254). The temperature sensor may include a heater temperature sensor attached to the heater (264).

[0312] The control unit (1340) can control the heater (264) based on temperature data detected by one or more temperature sensors.

[0313] According to an embodiment, the seat device (200) may include a separate seat control unit. The seat control unit may be mounted on a printed circuit board (246). The seat control unit may control the heater (264) of the seat device (200). The seat control unit may communicate with the control unit (1340) and operate the heater (264) based on a signal received from the control unit (1340).

[0314] The seat control unit can transmit data from the sensors to the control unit (1340). In addition, the seat control unit can receive sensing data from the weight sensor (244) and determine whether the pet is in the seat device (200). The seat control unit can receive sensing data from the temperature sensor and determine the temperature of the seat device (200) and / or the pet.

[0315] The seat device (200) includes a weight sensor (244) that detects the presence of a pet. The control unit (1340) recognizes whether a pet cat is present in the cat resting area of ​​the seat device (200) through the weight sensor (244) and controls the fan (140). The weight sensor (244) may be placed on the upper side of the lower body (211). The weight sensor (244) may detect the weight of the upper side of the upper part (250).

[0316] For example, the weight sensor (244) may be a load cell (244). Hereinafter, a case in which a load cell (244) is used will be described as an example.

[0317] The load cell (244) can measure the time the cat climbs onto the seat device (200) and the time the cat climbs off the seat device (200). In addition, the control unit (1340) can measure the resting pattern of the pet using the load cell (244).

[0318] The air purifier (1) can measure the point at which the cat goes up and down through the load cell (244) and control the heater (264) according to the logic.

[0319] If the control unit (1340) determines that the cat has climbed onto the seat device (200), it can turn on the heater (264) to perform a heating operation.

[0320] Additionally, based on temperature data detected by the temperature sensor during heating operation, the control unit (1340) can change the target temperature setting for controlling the heater (264).

[0321] The control unit (1340) can control the target temperature of the heater (264) based on the arrival time from the time when the pet is detected by the weight sensor (244) to the time when the change in temperature detected by the temperature sensor reaches the reference change temperature value.

[0322] Many cat warming products have traditionally controlled temperature with time settings, but low-temperature burns can occur depending on the situation.

[0323] However, the present disclosure controls the heating temperature provided by the sheet device (200) based on the load cell (244) value, the temperature sensor value, and time. Specifically, the temperature sensor is attached to the load cell (244) and the heater (264), and the time taken to reach the set temperature is measured. The control unit (1340) proactively controls the heater (264) based on the measured time data, thereby preventing low-temperature burns.

[0324] Thermal temperature control can prevent low-temperature burns by considering various variables, such as environmental temperature, cat weight, and cat temperature. Therefore, the present disclosure counts the time from the moment the cat is provided with thermal temperature and measures the time until the set temperature, which serves as a reference, is reached. The control unit (1340) estimates the variable environment based on the measured time data and controls the thermal temperature accordingly.

[0325] The control unit (1340) can determine whether a pet has climbed onto the seat device (200) using the load cell (244) value. In addition, the control unit (1340) can prevent low-temperature burns by measuring the time from when the pet uses the heating function and the time it takes to reach a set temperature, which serves as a reference, based on the temperature sensor provided in the seat device (200) and the load cell (244) value, and providing a heating temperature corresponding to the measurement result.

[0326] If the application (ex, ThinQ) retrieves pet type and age data, the control unit (1340) can provide a more comfortable temperature by controlling the temperature in response to the information obtained through the application.

[0327] The ThinQ app allows for more precise temperature control based on the cat breed (long-haired / short-haired) and age profile values ​​registered in the app. This prevents low-temperature burns and provides comfortable heating.

[0328] Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the drawings.

[0329] FIG. 14 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure, and exemplifies a temperature control process in recognition mode.

[0330] First, a target temperature for controlling the heater (264) can be set (S1410). The user sets the target temperature through switches (248a, 248b, 248c) or an application.

[0331] In recognition mode, if the target temperature is higher than the current temperature detected by the temperature sensor (S1415) and a pet is detected by the weight sensor (244) (S1420), the heater (264) performs heating operation (S1430).

[0332] If the target temperature is higher than the current temperature detected by the temperature sensor (S1415), it is checked whether the pet is in the seat device (200) (S1420). In recognition mode, the presence of the pet is checked using the weight sensor (244) (S1420), and the heater (264) is operated (S1430).

[0333] Meanwhile, the temperature sensor measures the initial temperature (T1) at the time the pet is detected by the weight sensor (244) (S1425). The measured initial temperature (T1) value can be stored in the memory (1330).

[0334] In the memory (1330), a temperature value (T1) detected by the temperature sensor at the time when a pet is detected by the weight sensor (244) (S1420) and the heater (264) operates can be stored.

[0335] The control unit (1340) can count the time (S1435) during which the pet is detected by the weight sensor (244) and heated. More preferably, the control unit (1340) can measure the elapsed time from the time of measuring the initial temperature (T1). In addition, the control unit (1340) can count the usage time of the heating function.

[0336] Meanwhile, the control unit (1340) can determine whether the set temperature has been reached (S1440). The set temperature may be the sum of the initial temperature (T1) and the reference change temperature value (ΔT). That is, the control unit (1340) can determine whether the temperature change amount due to the heating operation has reached the reference change temperature value (ΔT). For example, the reference change temperature value (ΔT) may be 3 degrees.

[0337] If the temperature changes faster than the target, it's likely that your pet's body temperature or the surrounding environment is causing the temperature to rise more rapidly. In this case, lowering the target temperature can slow the rate of temperature change.

[0338] The control unit (1340) can control the target temperature based on whether the set temperature is reached and the time it takes to reach the set temperature. The time it takes to reach the set temperature may be the same as the time it takes from the time the pet is detected by the weight sensor (244) to the time when the change in temperature detected by the temperature sensor reaches the reference change temperature value (ΔT).

[0339] The control unit (1340) can lower the target temperature by the first temperature when the first value based on the time taken to reach the reference change temperature value (ΔT) is equal to or greater than the first reference value.

[0340] Additionally, when the first value is greater than or equal to the second reference value that is smaller than the first reference value and less than the first reference value, the control unit (1340) can lower the target temperature by the second temperature that is smaller than the first temperature.

[0341] That is, if the temperature change is fast and the time taken to reach the reference change temperature value (ΔT) is short, low-temperature burns can be prevented by lowering the target temperature more significantly.

[0342] According to an embodiment, the amount of change in the target temperature can be set in proportion to the arrival time. That is, the control unit (1340) can lower the target temperature significantly as the arrival time of the reference change temperature value (ΔT) becomes shorter.

[0343] The first value based on the arrival time may be the arrival time itself or a ratio of the arrival time to a preset reference time. In this case, the reference values ​​corresponding to the first value may be set as time or percentage (%).

[0344] For example, if the time required to reach the reference change temperature value (ΔT) is 30 seconds, the reference values ​​can be set to 60 seconds and 45 seconds.

[0345] Or, if the time to reach the reference change temperature value (ΔT) is 30 seconds and the reference time is 60 seconds, the reference values ​​can be set to 200% and 150%.

[0346] Meanwhile, if the first value is less than the second reference value, the control unit (1340) maintains the target temperature. If the first value is less than the second reference value, the temperature change is slow. Therefore, the target temperature can be maintained, as it is determined that there is little possibility of further temperature increase due to the pet's body temperature or the surrounding environment.

[0347] Referring to FIG. 14, if the current temperature detected by the temperature sensor is greater than the sum of the temperature (T1) at the time when the heater (264) operates and the reference change temperature value (ΔT) (S1440), the control unit (1340) controls the target temperature of the heater (264) based on the arrival time (S1450 to S1475).

[0348] If the current temperature detected by the temperature sensor is less than the sum of the stored temperature (T1) and the reference change temperature value (ΔT) (S1440), the control unit (1340) maintains the current heating state (S1445).

[0349] The control unit (1340) calculates the first value (C1) (S1450).

[0350] For example, the first value (C1) may be the time taken to reach the reference change temperature value (ΔT).

[0351] Alternatively, the first value (C1) may be (reference time / reference change temperature value (ΔT) arrival time)*100.

[0352] The first and second reference values ​​can be set in response to the first value (C1). In FIGS. 14, 15, and 16, an example is described where the first value (C1) is (reference time / reference change temperature value (ΔT) arrival time)*100.

[0353] If the first value (C1) is greater than or equal to the first reference value (ex. 200%) (S1455), the control unit (1340) lowers the target temperature by 3 degrees (S1460).

[0354] New Target Temperature = Current Target Temperature - 3

[0355] If the first value (C1) is less than the first reference value (e.g., 200%) and greater than the second reference value (e.g., 150%) (S1465), the control unit (1340) lowers the target temperature by 1 degree (S1470).

[0356] New Target Temperature = Current Target Temperature - 1

[0357] That is, if the time taken to reach the reference change temperature value (ΔT) is short and the first value (C1) is greater than or equal to the second reference value (e.g., 150%), the target temperature is lowered. At this time, if the first value (C1) is significantly greater than the first reference value (e.g., 200%), the target temperature is lowered more significantly.

[0358] Meanwhile, if the first value (C1) is less than the second reference value (ex. 150%) (S1465), the control unit (1340) maintains the target temperature (S1475).

[0359] FIG. 15 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure, and exemplifies a temperature control process in a constant mode.

[0360] In the constant mode, when the heating function is turned on, heating is performed in response to the set target temperature. The constant mode differs from the recognition mode in that the heating operation begins regardless of whether a pet is detected by the weight sensor (244).

[0361] According to the target temperature set in the constant mode (S1510), the heater (264) performs heating operation (S1515).

[0362] The temperature sensor measures the temperature (T1) at the time when the pet is detected by the weight sensor (244) (S1530). The measured temperature (T1) value can be stored in the memory (1330).

[0363] In this embodiment, the target temperature and the current temperature detected by the temperature sensor can be compared (S1520).

[0364] Meanwhile, if the target temperature is higher than the current temperature detected by the temperature sensor (S1520) and a pet is detected by the weight sensor (244) (S1525), the temperature value (T1) detected by the temperature sensor at the time the pet is detected by the weight sensor (244) can be stored in the memory (1330) (S1530).

[0365] Additionally, the control unit (1340) can count the time from the time the pet is detected by the weight sensor (244) (S1535). More preferably, the control unit (1340) can measure the elapsed time from the time the temperature (T1) is measured.

[0366] Meanwhile, the control unit (1340) can determine whether the set temperature has been reached (S1540). The set temperature may be the sum of the initial temperature (T1) and the reference change temperature value (ΔT). That is, the control unit (1340) can determine whether the amount of temperature change due to the heating operation has reached the reference change temperature value (ΔT).

[0367] If the current temperature detected by the temperature sensor is less than the sum of the stored temperature (T1) and the reference change temperature value (ΔT) (S1540), the control unit (1340) maintains the current heating state (S1545).

[0368] If the current temperature detected by the temperature sensor is greater than the sum of the stored temperature (T1) and the reference change temperature value (ΔT) (S1540), the control unit (1340) calculates the first value (C1) (S1550).

[0369] For example, the first value (C1) may be the time taken to reach the reference change temperature value (ΔT). Alternatively, the first value (C1) may be (reference time / reference change temperature value (ΔT) reaching time)*100.

[0370] If the first value (C1) is greater than or equal to the first reference value (ex. 200%) (S1555), the control unit (1340) lowers the target temperature by 3 degrees (S1560).

[0371] If the first value (C1) is less than the first reference value (e.g., 200%) and greater than the second reference value (e.g., 150%) (S1565), the control unit (1340) lowers the target temperature by 1 degree (S1570).

[0372] Additionally, if the first value (C1) is less than the second reference value (ex. 150%) (S1565), the control unit (1340) maintains the target temperature (S1575).

[0373] FIG. 16 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure, and FIG. 17 is a drawing referenced in an explanation of temperature control based on pet information according to an embodiment of the present disclosure.

[0374] Users can register their pet's profile through a home appliance management application (e.g., ThinQ). The air purifier (1) can receive data related to the pet through the communication unit (1370). The received data can be stored in the memory (1330).

[0375] Additionally, users can set a target temperature (S1610) through a home appliance management application (e.g., ThinQ). Furthermore, users can turn on the heating function through a home appliance management application (e.g., ThinQ).

[0376] Meanwhile, temperature control utilizing additional pet-related data can be applied to both recognition mode and constant mode. While temperature control in constant mode is exemplified below, the same correction method can be applied to the first value (C1) described with reference to Figure 14.

[0377] According to the target temperature set in the constant mode (S1610), the heater (264) performs heating operation (S1615).

[0378] Meanwhile, if the target temperature is higher than the current temperature detected by the temperature sensor (S1620) and a pet is detected by the weight sensor (244) (S1625), the temperature sensor measures the temperature (T1) at the time the pet is detected by the weight sensor (244) (S1630).

[0379] Additionally, in the memory (1330), the temperature value (T1) detected by the temperature sensor at the time when the pet is detected by the weight sensor (244) can be stored (S1630).

[0380] The control unit (1340) can count the time from the time the pet is detected by the weight sensor (244) (S1635).

[0381] If the current temperature detected by the temperature sensor is less than the sum of the stored temperature (T1) and the reference change temperature value (ΔT) (S1540), the control unit (1340) maintains the current heating state (S1645).

[0382] If the current temperature detected by the temperature sensor is greater than the sum of the stored temperature (T1) and the reference change temperature value (ΔT) (S1540), the control unit (1340) calculates the first value (C1) (S1650).

[0383] Meanwhile, after calculating the first value (C1) (S1650), correction based on companion animal-related data can be performed for controlling the target temperature change amount (S1660 to S1680).

[0384] The control unit (1340) can adjust the amount of change in the target temperature in response to data related to the companion animal. For example, the control unit (1340) can set the amount of change in the target temperature according to the breed of the companion animal.

[0385] The control unit (1340) can increase the amount of change in the target temperature from the default value if the pet's hair length is less than the standard value, and can decrease the amount of change in the target temperature from the default value if the pet's hair length is greater than the standard value.

[0386] Figure 17 illustrates the existing target temperature change amount, the target temperature change amount in the case of a long hair, and the target temperature change amount in the case of a short hair, as described in Figures 15 and 16.

[0387] If the first value (C1) is greater than or equal to the first reference value (e.g., 200%) and the acquired pet data does not contain information on long hair / short hair (S1660), the control unit (1340) lowers the target temperature by the default value of 3 degrees (S1660). If the acquired pet data contains information on long hair / short hair, the target temperature change amount can be applied differently by reflecting the information as follows.

[0388] New Target Temperature = Current Target Temperature - 3

[0389] Mother-in-law New Target Temperature = Current Target Temperature - 2

[0390] Single New Target Temperature = Current Target Temperature - 4

[0391] If the first value (C1) is less than the first reference value (e.g., 200%) and more than the second reference value (e.g., 150%), and there is no information on long hair / short hair in the acquired pet data (S1670), the control unit (1340) lowers the target temperature by 1 degree from the default value (S1675).

[0392] If the acquired pet data contains information on long-haired / short-haired cats, the target temperature change amount can be applied differently as shown below by reflecting that information.

[0393] New Target Temperature = Current Target Temperature - 1

[0394] Mother-in-law New Target Temperature = Current Target Temperature - 1

[0395] Single New Target Temperature = Current Target Temperature - 2

[0396] Additionally, if the first value (C1) is less than the second reference value (ex. 150%) (S1565), the control unit (1340) maintains the target temperature (S1680).

[0397] 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.
