Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to an anti-tipping support device and a fireplace heater having the same. Background Technology

[0002] Currently, heaters are widely used in household appliances, especially for some heating equipment such as fireplaces. These types of heating appliances usually need to be equipped with support legs to adjust the height of the heating part, thereby increasing the user experience and providing better heating effect to the target area. In existing technology, the support legs are usually set at the bottom of the device. However, such support structures have obvious defects. In the prior art, a multi-functional furnace enclosure with the publication number CN223271312U has a point-support structure because each support leg is independent of the others, resulting in insufficient support stability and limited support area.

[0003] Especially in fireplace applications, when heavy items are placed on the heating surface, the support legs are prone to collapse in the circumferential direction. Similarly, for fireplace heaters with large surface areas, the use often involves placing heated items, such as cookware and kettles, on the edge of the surface. When such heavy items are placed on the edge of the surface, and their position is precisely in the middle of the angle between the two support legs, a large overturning moment is generated, further increasing the risk of tipping over. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a support device to prevent tipping.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an anti-tipping support device, including a mounting base and support legs disposed at the bottom of the mounting base, the support legs being arranged at intervals around the mounting base, each support leg including an upper connecting part and a lower connecting part, the upper connecting part being fixedly connected to the mounting base, the lower connecting part being connected to a support base, the support base being connected between multiple lower connecting parts and providing a support reference surface.

[0006] Furthermore, the support base is connected to the lower connecting part and together they form a surrounding support frame, or the support base is supported on the bottom of the lower connecting part and forms a surrounding support frame.

[0007] Furthermore, the minimum outer envelope circle diameter of the projection of the support base onto the horizontal plane is greater than the minimum outer envelope circle diameter of the projection of the mounting base onto the horizontal plane.

[0008] Furthermore, the support leg is inclined outward about the center line of the mounting base.

[0009] Furthermore, the lower connecting portion is inclinedly connected to the support base. The support base also prevents the support leg from expanding obliquely upwards.

[0010] Furthermore, the support base is provided with a fixing seat for inserting the lower connecting part, and a support structure is provided between the fixing seat and the outer edge of the base with respect to the inclined direction of the support leg.

[0011] Furthermore, the mounting base is provided with an insert, which includes a socket that is embedded in the mounting base and a support connection portion that extends out of the bottom of the mounting base, wherein the upper connection portion is fixedly engaged with the support connection portion.

[0012] Furthermore, the bottom of the mounting base is provided with a receiving seat for inserting the insert. The receiving seat and the insert are provided with an anti-rotation engagement structure and a center positioning structure. The anti-rotation engagement structure and the center positioning structure are mutually engaged in an interlocking manner, and the anti-rotation engagement part is provided with a first locking structure.

[0013] The present invention also provides a fireplace heater, including the above-mentioned support device, including a shell assembly, wherein a heating unit is provided inside the shell assembly, the shell assembly includes a mounting base and a casing, and a heating platform disposed above the casing, wherein a heating area corresponding to the heating unit is provided on the heating platform.

[0014] Furthermore, the mounting base is equipped with an anti-tipping switch.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: by setting a connecting support base at the bottom of multiple support legs, the present invention transforms the traditional independent point support into an overall frame or surface support, thereby improving the stability and support area of ​​the support device. Meanwhile, the support base also increases the contact profile with the ground, ensuring the anti-tipping ability of the support device at the fulcrum line between the two support legs, reducing the risk of overturning caused by accidental collisions or placing heavy objects on the edge, and greatly improving the safety and stability of the product.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0019] like Figure 1-10 As shown, An anti-tipping support device includes a mounting base 1 and multiple support legs 2 disposed at the bottom of the mounting base 1. The support legs 2 are arranged at intervals around the mounting base 1. Each support leg 2 includes an upper connecting part 2.1 and a lower connecting part 2.2. The upper connecting part 2.1 is fixedly connected to the mounting base 1, and a support base 3 is connected to the lower connecting part 2.2. The support base 3 is connected between the multiple lower connecting parts 2.2 and provides a support reference surface.

[0020] The support base 3 is composed of connecting components, which are connected end to end to the lower connecting part 2.2 of the support leg 2, and together they form a rigid support frame surrounding the mounting base 1. This transforms the traditional independent point support into an integral frame support, which greatly increases the contact profile and stability between the support device and the ground. In addition, the support base 3 provides a regular support reference surface, which effectively resists the overturning moment caused by uneven ground, accidental collisions, or eccentric loads applied to the upper part of the equipment, thus fundamentally solving the risk of tipping over.

[0021] It should be noted that the fixed connection between the upper connecting part 2.1 and the lower connecting part 2.2 refers to the fixed support in the assembled state. The support leg 2 can be detachably connected to the mounting base 1 through the upper connecting part 2.1, or it can be detachably connected to the support base 3 through the upper connecting part 2.1. Of course, in some embodiments, the upper connecting part 2.1 can also be integrally connected to the mounting base 1, and the lower connecting part 2.2 can also be integrally connected to the support base 3. In this embodiment, it is preferable to use a detachable connection between the support leg 2 and the mounting base 1 and the support base 3 to facilitate molding and assembly transportation.

[0022] In this embodiment, the support base 3 is preferably set as a ring shape, so that the support base 3 has the same support radius in any horizontal direction, thereby resisting the overturning moment from different directions. In addition, the inner circle of the ring-shaped support base 3 naturally forms an unobstructed space, so that when the user approaches the heater, his toes can naturally reach into the inner side of the ring, allowing him to get closer to the device. Whether adjusting settings, observing the fire, or taking items from the central area, it is more comfortable and convenient.

[0023] In addition, the support base 3 can also be other irregular shapes. Its main purpose is to connect the bottom of the support leg 2 and provide a support reference surface to provide anti-overturning capability for the connecting area of ​​adjacent support legs 2. For example, the connecting component can be set as a V-shaped strip member that spreads from the center of the support device, or it can be set as a square frame. The support base 3 can also be set as an integral circle to form a surrounding support frame. In other words, the above-mentioned surrounding arrangement refers to connecting the bottoms of multiple support legs 2.

[0024] As a further embodiment of the cooperation between the support base 3 and the support leg 2, preferably, the support base 3 is an integral structure composed of multiple connecting parts. For example, the support base 3 is a complete ring and docks with the lower connecting part 2.2 of each support leg 2, thereby supporting the entire support device and the bottom of the lower connecting part 2.2 to form a surrounding support frame, forming a closed rigid ring structure. This can effectively distribute the lateral forces (such as collision forces and horizontal component forces generated by object offset) on each support leg 2 to the entire frame, which is borne by the frame as a whole, greatly enhancing the support device's ability to resist lateral tilting and internal collapse.

[0025] In this embodiment, the support base 3 provides a complete support reference surface, and the lower connecting part 2.2 is used as a connecting member with the support base 3.

[0026] In other embodiments, the lower connecting portion 2.2 also participates in the formation of the support reference surface, and together with the support base 3, it forms a surrounding support frame. In this embodiment, the lower connecting portion 2.2 passes through the support base 3 and is in contact with the placement surface of the support device.

[0027] Specifically, the minimum outer envelope diameter of the projection of the support base 3 onto the horizontal plane is greater than the minimum outer envelope diameter of the projection of the mounting base 1 onto the horizontal plane. This quantifies and ensures that the support base is larger than the body contour of the mounting base in terms of geometric dimensions. This feature provides a larger stability domain for the support base 3. When subjected to overturning moment, a larger force is required to make it roll around the edge of the support base 3, thereby achieving a reliable anti-tipping effect in the structure.

[0028] In applications of the support device to other electrical appliances, especially in fireplace heaters, it is preferable that the projected outline of the support base 3 is larger than the outline of the fireplace platform of the fireplace heater.

[0029] from Figure 1 As can be seen, specifically, the support leg 2 is inclined outward about the center line of the mounting base 1, forming a stable structure similar to a frustum or truncated cone, which further enhances stability. Since the outline of the support base 3 is defined by the bottom of the support leg 2, this type of support leg 2 layout is conducive to the support base 3 providing a more stable support reference surface.

[0030] Further reference Figure 5 The lower connecting part 2.2 is inclinedly connected to the support base 3. The support base 3 prevents the support leg 2 from expanding obliquely upward. Through its rigid structure, the support base 3 effectively prevents the support leg 2 from expanding obliquely upward when under force, thus tightening the support leg 2 and preventing the support structure from deforming and loosening due to long-term use or overload under heavy pressure or lateral force, ensuring long-term stability and reliability.

[0031] Specifically, the support base 3 is provided with a fixing seat 4 for inserting the lower connecting part 2.2. A support structure 5 is provided between the fixing seat 4 and the outer edge of the base, oriented with respect to the inclined direction of the supporting leg 2. The opening direction of the fixing seat 4 extends along the inclined direction of the supporting leg 2, and the bottom wall of the fixing seat 4 is perpendicular to the supporting leg 2, providing a high-strength dedicated connection and stress-bearing node for the inclined supporting leg 2. The support structure 5 specifically refers to a connecting rib provided between the bottom wall of the fixing seat 4 and the outer edge of the support base 3. This connecting rib can be set at an angle to the supporting leg 2. The support structure 5, oriented with respect to the inclined direction of the supporting leg 2, can more effectively transfer and distribute the pressure and lateral force distributed to the leg to the entire support base 3, avoiding stress concentration and enhancing the structural strength and durability of the connection point.

[0032] In addition, multiple reinforcing ribs are provided on the inner side of the support base 3.

[0033] Preferably, the fixing seat 4 and the lower connecting part 2.2 are tightened and fixed by bolts.

[0034] like Figures 6 to 8 As shown, in a further embodiment of the connection between the mounting base 1 and the support leg 2, the mounting base 1 is provided with an insert 6. The insert 6 includes a base 6.1 that is embedded in the mounting base 1 and a support connection portion 6.2 that extends out of the bottom of the mounting base 1. The support connection portion 6.2 is arranged in the same direction as the support leg 2 and is inclined to the base 6.1. The upper connection portion 2.1 is fixedly engaged with the support connection portion 6.2. The insert 6 connects the mounting base 1 and the support leg 2. On the one hand, this simplifies the molding of the mounting base 1, eliminating the need to provide an inclined connection portion for the support leg 2 to be connected on the mounting base 1. On the other hand, the independently provided insert 6 provides a stronger connection strength than the mounting base 1. The insert 6 can be made of a material with greater strength. For example, the mounting base 1 can be made of PP material, and the insert 6 and the support leg 2 can be made of ABS material to improve the reliability of the assembly of the support leg 2 and avoid stripping or tearing of the mounting hole caused by repeated stress on the support leg 2.

[0035] Further reference Figure 7 and Figure 8 As shown, specifically, the bottom of the mounting base 1 is provided with a receiving seat 1.1 for inserting the insert 6. There is an anti-rotation fitting structure 7 and a center positioning structure 8 between the receiving seat 1.1 and the insert 6.1. The anti-rotation fitting structure 7 and the center positioning structure are mutually fitted in a fitting manner, and the anti-rotation fitting part is provided with a first locking structure 9. The anti-rotation and positioning structures ensure the accurate installation angle and prevent the support leg 2 from rotating and misaligning during use.

[0036] Specifically, the anti-rotation fitting structure 7 includes a connecting protrusion 7.1 provided on the insert 6.1, with multiple connecting protrusions radially protruding from the outer wall of the insert 6.1, and also includes multiple connecting recesses 7.2 provided at the bottom of the mounting base 1, with the connecting protrusion 7.1 embedded in the connecting recesses. The anti-rotation fitting structure 7 is provided with a first locking structure 9, which refers to a threaded hole 9.1 provided on the connecting protrusion 7.1 and a through hole 9.2 provided on the connecting recess, thereby pulling the insert 6 tightly to the bottom of the mounting base 1; The center-fitting structure includes a first annular protrusion 8.1 disposed within the insert 6.1, the first annular protrusion 8.1 being spaced apart from the annular outer wall of the insert 6.1, and a second annular protrusion 8.2 disposed at the bottom of the mounting base 1, the second annular protrusion 8.2 corresponding to the space between the first annular protrusion 8.1 and the annular outer wall of the insert 6.1; the center-fitting structure also includes a positioning post disposed at the center of the insert 6.1, and the bottom of the mounting base 1 is provided with a positioning hole corresponding to the positioning post. Through the above-mentioned center-fitting structure and anti-rotation fitting structure 7, the insert 6 is reliably connected to the bottom of the mounting base 1.

[0037] like Figure 9 good Figure 10 As shown, the present invention also provides a fireplace heater, including the above-mentioned support device, and also includes a housing assembly 10. The housing assembly 10 is provided with a heating unit 11. The housing assembly 10 includes a mounting base 1 and a casing 10.1, and a heating platform 12 disposed above the casing 10.1. The heating platform 12 is provided with a heating area 12.1 corresponding to the heating unit 11.

[0038] Applying the aforementioned support device to a fireplace-style heater can effectively resist the enormous overturning moment caused by the offset of heavy objects on the heating platform, preventing the heater from tipping over and thus avoiding serious safety accidents such as burns and fires that may be caused by tipping over, greatly improving the safety of the product.

[0039] Specifically, an anti-tipping switch 13 is installed inside the mounting base 1. This anti-tipping switch 13, together with the mechanical anti-tipping structure of this invention, forms a "double electromechanical insurance" safety strategy. Its technical advantage is that even if the heater tilts at a slight angle due to a large external force, before reaching the limit of mechanical stability, the anti-tipping switch 13 can promptly cut off the power supply to the heating unit 11, eliminating the potential danger of continued heating from the source, achieving active safety protection, and further enhancing the product's safety level.

[0040] In addition, the support base 3 provides a larger support surface, which can give the heater more precise tilt position feedback when placed in some uneven areas, thus improving the safety of use.

[0041] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
