[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] Combination Figures 1-10 As shown, in some embodiments, the movable home appliance includes: a support chassis 100, differential drive wheels 200, and a functional module 300. Each corner region of the support chassis 100 is provided with casters 101; the differential drive wheels 200 are embedded in the lower side wall of the support chassis 100 and located in the middle of the side of the support chassis 100; the functional module 300 is disposed on the upper side of the support chassis 100.

[0042] The movable home appliance provided in this embodiment achieves its functions by setting a functional module 300 on the upper side of the support chassis 100. The support chassis 100 carries the functional module 300 to move within the indoor environment, improving the efficiency of the functional module 300. Universal wheels 101 are provided at each corner of the support chassis 100, and differential drive wheels 200 are located in the middle area of ​​the side of the support chassis 100 to drive the chassis 100 and achieve steering. The cooperation between the universal wheels 101 at the corners of the support chassis 100 and the differential drive wheels 200 on the sides better adapts to complex indoor terrain and improves the stability of movement.

[0043] Optionally, the lower sidewall of the support chassis 100 is rectangular, and each of the four corner areas of the lower sidewall of the support chassis 100 is equipped with casters 101. In this way, the support chassis 100 with rectangular structure has casters 101 installed at each of the four corner areas, which can improve the movement stability of the support chassis 100 and better adapt to complex indoor terrain environments.

[0044] Optionally, the four corners of the support chassis 100 are rounded. This makes the four corners of the support chassis 100 smoother, reducing the risk of damaging other home appliances in the indoor environment in the event of a collision.

[0045] Optionally, two differential drive wheels 200 are provided, with each wheel located at the midpoint of one of the two opposite sides of the lower sidewall of the supporting chassis 100. By setting two differential drive wheels 200 at the midpoints of the opposite sides of the supporting chassis 100, the synchronous rotation of the two differential drive wheels drives the movement of the supporting chassis 100. The differential rotation of the two differential drive wheels enables steering of the supporting chassis 100, improving its stability. Furthermore, with both differential drive wheels located at the midpoints of their respective sides, the supporting chassis 100 experiences more even force distribution and a more stable center of gravity when driven by the differential drive wheels 200.

[0046] For example, the support chassis 100 moves in the front-to-back direction, and the differential drive wheel 200 is located at the middle position of the two sides of the support chassis 100 in the front-to-back direction. The axes of the two differential drive wheels 200 coincide, and the line connecting the two differential drive wheels 200 in the axial direction coincides with the center line of the support chassis 100.

[0047] Optionally, the support chassis 100 has mounting grooves 102 at the middle of both sides along the front-rear direction. Two differential drive wheels 200 are respectively embedded in the corresponding mounting grooves 102. On the upper side of the support chassis 100, corresponding to each mounting groove 102, there is a receiving box 103. The upper half of the differential drive wheel 200 is embedded in the receiving box 103 along the mounting groove 102, and the lower half of the differential drive wheel 200 protrudes along the lower side wall of the support chassis 100. In this way, the upper half of the differential drive wheel 200 is hidden inside the support chassis 100. The receiving box 103 can block and contain contaminants kicked up by the differential drive wheel 200 during rotation, preventing contaminants from entering the support chassis 100 and causing pollution.

[0048] Combination Figures 2-4 As shown, in one embodiment, the support chassis 100 includes a chassis body 110 and a housing 120. Each corner region of the lower sidewall of the chassis body 110 is provided with a caster wheel 101, and a differential drive wheel 200 is embedded in the lower sidewall of the chassis body 110. The housing 120 covers the upper side of the chassis body 110, and a functional module 300 is disposed on the upper side of the housing 120. The interior of the housing 120 defines an installation space 121. Thus, the support chassis 100 is divided into a chassis body 110 and a housing 120. The chassis body 110 is used to install and support the caster wheels 101 and the differential drive wheel 200, while the housing 120 defines the installation space 121 to accommodate other components of the movable home appliance.

[0049] Optionally, the disc body 110 has a rectangular plate structure with rounded corners at all four corners, and the outer shell 120 also has a rectangular shell structure with rounded corners at all four corners. This rectangular plate structure of the disc body 110 facilitates the installation of the caster wheel 101 and the differential drive wheel 200, providing more stable support. By adapting the shape of the outer shell 120 to the shape of the disc body 110, the shape of the support chassis 100 becomes more regular. The rounded corners at the four corners of both the disc body 110 and the outer shell 120 make the corners of both more rounded, reducing the risk of damage to other household equipment in the event of a collision.

[0050] Specifically, the mounting slot 102 is located in the middle of the two sides of the disk body 110 along the front-back direction, and the accommodating box 103 is located on the upper side wall of the disk body 110 and inside the outer shell 120.

[0051] Optionally, each of the four corner areas of the disc body 110 is provided with a mounting hole 111, and the caster wheel 101 is mounted in the corresponding mounting hole 111. In this way, mounting the caster wheel 101 in the mounting hole 111 can improve the installation stability of the caster wheel 101.

[0052] Optionally, in the vertical direction, the lower end of the caster wheel 101 is positioned above the lower end of the differential drive wheel 200. This ensures that the lower end of the differential drive wheel 200 is always in contact with the ground, providing better drive for the supporting chassis 100.

[0053] Optionally, such as Figure 4 As shown, the movable home appliance also includes a drive assembly 400 and a controller 500. The drive assembly 400 is disposed within the mounting space 121 and is used to drive the rotation of the differential drive wheel 200; the controller 500 is disposed within the mounting space 121 and is used to control the drive assembly 400. Thus, the drive assembly 400 drives the differential drive wheel 200 to rotate, thereby moving the support chassis 100. The controller 500 can control the drive assembly 400 according to preset instructions or user-input instructions, thereby controlling the rotation of the differential drive wheel 200 and thus controlling the movement of the movable home appliance.

[0054] Optionally, each differential drive wheel 200 is provided with a corresponding drive assembly 400, and the two drive assemblies 400 are located between the two differential drive wheels 200. In this way, since there are two differential drive wheels 200, two drive assemblies 400 are provided accordingly. The two drive assemblies 400 drive the corresponding differential drive wheel 200 respectively, so that while the differential drive wheel 200 rotates, differential drive can also be achieved, thereby enabling the chassis 100 to steer.

[0055] Specifically, both drive components 400 are fixed to the upper side wall of the disk body 110.

[0056] Optionally, the drive assembly 400 includes a drive motor and a differential gearbox, with the output shaft of the drive motor rotatably connected to the differential drive wheel 200 via the differential gearbox. In this way, by utilizing the cooperation of the drive motor and the differential gearbox, the two differential drive wheels 200 can rotate at different speeds, thereby enabling the chassis 100 to steer and better adapt to complex indoor terrain environments.

[0057] Understandably, the controller 500 synchronously controls the drive motors of the two drive components 400, and by controlling the speed of the drive motors, the differential rotation of the two differential drive wheels 200 is achieved.

[0058] Optionally, the portable home appliance also includes a power storage unit 600. The power storage unit 600 is disposed within the installation space 121 and provides power to the drive assembly 400. Thus, by providing power to the drive assembly 400 through the power storage unit 600, the portable home appliance is moved by the drive assembly 400 driving the differential drive wheel 200, thereby improving the range of the portable home appliance.

[0059] Optionally, the energy storage unit 600 is located between the two drive components 400. This facilitates the electrical connection between the two drive components 400 and the energy storage unit 600.

[0060] Optionally, the energy storage unit 600 includes a lithium battery. This allows the lithium battery to store a larger amount of energy, thus improving the battery life of the portable home appliance.

[0061] Optionally, the outer wall of the housing 120 is provided with a charging port 122, which is electrically connected to the power storage unit 600. In this way, the power storage unit 600 can be charged through the charging port 122 to replenish its power and improve the battery life of the portable home appliance.

[0062] Optionally, such as Figure 4 As shown, an obstacle avoidance component 700 is provided on the outer side wall of the support chassis 100. In this way, the obstacle avoidance component 700 can detect obstacle information in the environment surrounding the support chassis 100, so that the support chassis 100 can avoid obstacles during movement and better adapt to complex terrain environments.

[0063] Optionally, the obstacle avoidance component 700 establishes a communication connection with the controller 500. The controller 500 can obtain obstacle information detected by the obstacle avoidance component 700 to control the drive component 400, thereby controlling the movement direction of the support chassis 100. In this way, the controller 500 controls the drive component 400 based on the obstacle information detected by the obstacle avoidance component 700, enabling the support chassis 100 to avoid obstacles during movement and better adapt to complex indoor terrain environments.

[0064] Understandably, the obstacle avoidance component 700 and the controller 500 are both powered by the energy storage unit 600.

[0065] Combination Figure 5 As shown, in one embodiment, the obstacle avoidance component 700 includes a dual-line laser device 710 and an infrared sensor 720. The dual-line laser device 710 is disposed on the front sidewall of the supporting chassis 100; the infrared sensor 720 is disposed on the rear sidewall of the supporting chassis 100.

[0066] In this embodiment, the obstacle avoidance component 700 is divided into an infrared sensing device 720 and a dual-line laser device 710. The infrared sensing device 720 and the dual-line laser device 710 are respectively installed on the front and rear side walls of the support chassis 100. The infrared sensing device 720 and the dual-line laser device 710 detect obstacle information in front of and behind the support chassis 100 and feed it back to the controller 500. The controller 500 controls the movement direction of the support chassis 100 according to the feedback obstacle information to perform reasonable obstacle avoidance and better adapt to complex terrain environments.

[0067] Optionally, the obstacle avoidance assembly 700 also includes a collision avoidance device 730. The collision avoidance device 730 is a collision avoidance radar, installed on the front side wall of the support chassis 100, used to detect obstacle information in the environment in front of the collision avoidance device 730 and feed it back to the controller 500. Thus, by installing the collision avoidance device 730, the obstacle avoidance capability of the support chassis 100 is further improved. Since the support chassis 100 moves forward most of the time, the collision avoidance device 730 is installed on the front side wall of the support chassis 100.

[0068] Specifically, the dual-line laser device 710 and the anti-collision device 730 are disposed on the outer side wall of the housing 120, and the infrared sensing device 720 is disposed on the rear side wall of the housing 120.

[0069] Combination Figure 6 As shown, in another embodiment, two obstacle avoidance components 700 are provided, and the two obstacle avoidance components 700 are respectively disposed on the front side wall and the rear side wall of the supporting chassis 100.

[0070] In this embodiment of the present disclosure, by providing obstacle avoidance components 700 on both the front and rear side walls of the support chassis 100, and using the two obstacle avoidance components 700 to detect obstacle information in front of and behind the support chassis 100 and feed it back to the controller 500, the obstacle avoidance capability of the support chassis 100 can be improved, and it can better adapt to complex terrain environments.

[0071] Optionally, each obstacle avoidance component 700 includes an infrared sensor 720 and a dual-line laser device 710. Thus, by providing the infrared sensor 720 and the dual-line laser device 710 on both the front and rear side walls of the support chassis 100, the obstacle avoidance capability of the support chassis 100 can be further improved.

[0072] Optionally, the obstacle avoidance assembly 700 also includes a collision avoidance device 730. Thus, by providing collision avoidance devices 730 on both the front and rear side walls of the supporting chassis 100, the obstacle avoidance capability of the supporting chassis 100 can be further improved.

[0073] Combination Figures 7-9 As shown, in one embodiment, functional module 300 includes: humidification module 310, or dehumidification module 320.

[0074] Combination Figure 7 As shown, in one specific embodiment, the functional module 300 includes a humidification module 310. Thus, by placing the humidification module 310 on the upper side of the support chassis 100, the portable home appliance possesses a humidification function. By carrying the humidification module 310 through the support chassis 100 within the indoor environment, the humidification module 310 humidifies the areas traversed by the support chassis 100, improving the uniformity of humidification in the indoor environment and enhancing the humidification effect.

[0075] Optionally, the humidification module 310 includes a water tank 311 and a humidification generator 312. The water tank 311 is disposed on the upper side of the support chassis 100; the humidification generator 312 is disposed on the upper side of the water tank 311 and is connected to the water tank 311. In this way, the humidification module 310 is divided into a water tank 311 and a humidification generator 312. The water tank 311 can store humidification water to improve the humidification endurance, and the humidification generator 312 draws water from the water tank 311 for humidification, thereby improving the humidification effect of the indoor environment.

[0076] Optionally, the humidifier 312 is an atomizing humidifier. In this way, by drawing water stored in the water tank 311 for atomizing humidification, the humidification effect is improved.

[0077] Combination Figure 8 and Figure 9As shown, in another specific embodiment, the functional module 300 includes a dehumidification module 320. Thus, by placing the dehumidification module 320 on the upper side of the support chassis 100, the portable home appliance possesses a dehumidification function. By having the support chassis 100 carry the dehumidification module 320 through the indoor environment, and by utilizing the dehumidification module 320 to dehumidify the areas traversed by the support chassis 100, the uniformity of dehumidification in the indoor environment is improved, thereby enhancing the dehumidification effect.

[0078] Optionally, the dehumidification module 320 includes a water collection tray 321, a dehumidification duct 322, and a heating duct 323.

The hot end is located within the heating duct 323, and both the air inlet and outlet of the heating duct 323 are also connected to the indoor environment. In this way, indoor air flows into the dehumidification duct 322 and comes into contact with the cold end for condensation and dehumidification. At the same time, the dehumidified indoor air flows into the heating duct 323 and exchanges heat with the hot end for heating, reducing the impact of dehumidification on the indoor temperature.

[0079] Combination Figure 10 As shown, in another embodiment, the functional module 300 is provided in multiple ways, and the multiple functional modules 300 are a humidification module 310 and a dehumidification module 320, and any one of the humidification module 310 and the dehumidification module 320 is detachably disposed on the upper side of the support chassis 100.

[0080] In this embodiment of the disclosure, by setting multiple functional modules 300, namely a humidification module 310 and a dehumidification module 320, any one of the humidification module 310 and the dehumidification module 320 can be detachably installed on the upper side of the support chassis 100 according to the user's needs, thereby realizing the corresponding humidification and dehumidification functions and improving the user experience.

[0081] For example, the lower sidewalls of the humidification module 310 and the dehumidification module 320 are provided with magnetic suction parts, and the upper sidewall of the housing 120 is provided with a magnetic metal strip. The humidification module 310 and the dehumidification module 320 are detachably connected to the upper sidewall of the housing 120 through the cooperation of the magnetic suction parts and the magnetic metal strip.
