[0023] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an arc-shaped base and a household appliance of the present invention in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, in order to prevent household appliances from tipping over, the present invention provides an arc-shaped base 2, which can be used for the base 2 of taller household appliances such as tower fans, floor fans, tower cooling fans, and tower heaters.

[0025] like Figure 3-Figure 4 As shown, the arc base 2 includes a hemispherical shell 21 and a cover plate 22 covering the opening of the shell 21. A counterweight block 23 is provided in the shell 21. The shell 21 also includes a plurality of clamp assemblies 3 for fixing the body 1 of the household appliance. The plurality of clamp assemblies 3 are distributed along the circumference of the cover plate 22. The body 1 is placed between the clamp assemblies 3. The bottom end of the clamp assembly 3 is radially slid along the cover plate 22 and fixed on the cover plate 22. The clamp assembly 3 presses the body 1 and fixes the body 1 on the cover plate 22.

[0026] like Figure 1 As shown, three clamp assemblies 3 are arranged on the arc base 2, and the three clamp assemblies 3 are evenly distributed along the circumference of the cover plate 22. The fuselage 1 is placed between the three clamp assemblies 3, and the three clamp assemblies 3 are slid to press the fuselage 1 along three directions to fix the fuselage 1 in the circumferential direction and the axial direction.

[0027] The household appliance is an external-type tower fan, with a chassis 11 provided on the bottom surface of the body 1, an air duct provided inside the body 1, the air duct and the chassis 11 being relatively fixed, and the air duct and the body 1 being relatively rotated, and at this time, the arc-shaped base 2 must be relatively fixed with the chassis 11. In this case, the diameter of the chassis 11 is larger than the diameter of the body 1, the diameter of the cover plate 22 is larger than the diameter of the chassis 11, the clamp assembly 3 includes a column 31, the top of the column 31 is provided with a support rod 32 facing the direction of the body 1, the bottom surface of the support rod 32 contacts the top surface of the chassis 11, and the clamp assembly 3 slides and fixes along the radial direction of the cover plate 22 so that the inner wall of the column 31 is pressed against the outer wall of the chassis 11, thereby limiting the radial and axial movement of the chassis 11.

[0028] In order to make the clamp assembly 3 applicable to chassis 11 of different thicknesses, Figure 2 As shown, the support rod 32 is above the chassis 11, and the clamp assembly 3 also includes an adjusting bolt 4 arranged along the axial direction of the fuselage 1. The support rod 32 is provided with a threaded hole that cooperates with the adjusting bolt 4. The adjusting bolt 4 is tightened on the support rod 32, and the bottom end of the adjusting bolt 4 abuts against the top surface of the chassis 11, thereby expanding the application range of the clamp assembly 3.

[0029] The chassis 11 is generally a plastic shell. In order to prevent the chassis 11 from being damaged during the tightening process of the adjusting bolt 4, a pressure block 41 made of rubber material is provided at the bottom end of the adjusting bolt 4. By providing the pressure block 41, on the one hand, the contact area between the adjusting bolt 4 and the chassis 11 is increased, and on the other hand, the rubber material plays a role of buffering protection and prevents the chassis 11 and the adjusting bolt 4 from sliding relative to each other.

[0030] When the household appliance is an inward-turned tower fan, a floor fan or other fan whose chassis 11 is relatively fixed to the body 1, the body 1 can be directly fixed on the arc-shaped base 2, and the clamp assembly 3 includes a pressure rod 34 along the axial direction of the body 1, and a pressing surface matching the side wall of the body 1 is provided on the pressure rod 34 facing the body 1, and a fastening structure is provided on the pressing surface to limit the radial and axial movement of the body 1. The fastening structure is an anti-skid protrusion or anti-skid rib made of rubber material.

[0031] In order to make the clamp assembly 3 suitable for different types of products and make the clamp assembly 3 more versatile, the clamp assembly 3 also includes a support rod 32 connected to the end of the pressure rod 34, and the other end of the support rod 32 is provided with a column 31 along the axial direction of the fuselage 1. The bottom end of the column 31 is slidably fixed on the cover plate 22, and the support rod 32 is provided with a threaded hole that cooperates with the adjustment bolt 4. By designing a clamp assembly 3 suitable for fixing products of different types and sizes, the versatility is enhanced.

[0032] In order to enable the clamp assembly 3 to slide and fix radially along the cover plate 22, in one embodiment, a bottom rod 33 is provided at the bottom end of the column 31, a mounting hole is provided on the bottom rod 33, and a long strip-shaped adjustment hole 221 is radially provided on the cover plate 22, and the bottom rod 33 is fixed to the cover plate 22 by fasteners.

[0033] In another embodiment, a bottom rod 33 is provided at the bottom end of the column 31, and a threaded hole is provided on the bottom rod 33. An adjustment groove is radially provided on the cover plate 22. The cross-section of the adjustment groove is an inverted trapezoid. The end of the adjustment groove passes through the side wall of the cover plate 22. The bottom end of the bottom rod 33 is an inverted trapezoidal structure that cooperates with the adjustment groove. After the clamp assembly 3 has finished sliding, the bottom rod 33 is fixed to the cover plate 22 by fasteners, thereby realizing the fixation of the clamp assembly 3 and the base 2.

[0034] When the body 1 and the cover 22 are relatively fixed, a plurality of internal threaded holes are provided on the bottom surface of the cover 22, and the opening of the hemispherical shell 21 is folded outward to form a flange 211, and a fixing hole matching the internal threaded hole is provided on the flange. The screw 5 is tightened in the internal threaded hole, and the screw 5 passes through the fixing hole, so that the shell 21 is fixed on the cover 22, thereby completing the installation of the household appliance.

[0035] The present application also provides a household appliance, including the above-mentioned arc-shaped base 2, and the problem of easy tipping of existing household appliances is effectively solved by fixing the body 1 on the arc-shaped base 2.

[0036] The arc base 2 can be used for installation and fixation of various household appliances. A plurality of clamp assemblies 3 are arranged on the arc base 2. The clamp assemblies 3 are slidably fixed on the arc base 2. The household appliances are fixed by pressing and fixing, which is convenient for assembly and disassembly and improves production efficiency.

[0037] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
