Detailed Description

In the various figures of the present application, features that are structurally identical or functionally similar are denoted by the same reference numerals.

Fig. 1 schematically shows an outdoor heating furnace 100 according to an embodiment of the application. As shown, the outdoor heating furnace 100 includes a burner base 200, a burner 300, a burner 350, a heater 400, and a furnace cover 500.

The furnace base 200 has a main body 210. The body 210 is generally hollow and cylindrical and may be formed, for example, by bend welding sheet metal such as stainless steel. It should be clear that the main body 210 of the hob 200 may also be formed in other suitable hollow shapes, such as a hollow cuboid shape. A closed end 215 is provided at the top of the body 210. A base 220 is coupled to the bottom of the body 210. The base 220 is for contacting the ground. A plurality of support pieces 221 are dispersedly provided on the periphery of the base 220 near the ground. The base 210 and the leg 220 may be made of the same metal as the main body 210 so that the leg 221 may be locked to the base 210 using a fastener. In an alternative embodiment, welded to the base 210. As shown in fig. 2D, the supporting pieces 221 radially protrude from the base 210, and serve to provide an auxiliary support for the outdoor heating stove 100 to the ground, so as to prevent the outdoor heating stove 100 from falling down. In addition, the support pieces 221 may also be used to ensure that the outdoor heating stove of the present application does not fall down accidentally, for example, in which case the support pieces may be fixed to the top surface by ground nails, in which case the support pieces function as rivet claws. Further, a roller bracket 223 is provided on the periphery of the base 220, so that a pair of rollers 222 (shown in fig. 2B and 2D) are coaxially rotatably supported by the roller bracket 223. The roller bracket 223 is configured such that, when the outdoor heating furnace 100 needs to stand still on the ground, the roller 222 does not contact the ground; and when the outdoor heating furnace 100 needs to be moved as a whole, the user can contact the roller 222 with the ground only by slightly tilting the outdoor heating furnace 100 towards the direction of the roller bracket 223, and then the user can conveniently move the tilted outdoor heating furnace 100 by using the roller 222 in contact with the ground, thereby moving the position as required. After reaching the desired position, the user may stand the outdoor heating furnace 100 again.

The main body 210 of the furnace base 200 is provided with an openable and closable door 224. The door 224 is mounted in the wall of the main body 210 via a pair of hinges. Thus, by opening the door 224, the interior space 210a (shown in FIG. 2E) surrounded by the hollow body 210 is accessible. The internal space 210a is used to accommodate a gas canister (not shown). A plurality of openings are formed in the main body 210 so that the outside can communicate with the inner space 210a, ensuring that gas does not accumulate in the base 200 to cause a danger even if the gas is accidentally leaked.

The furnace neck 300 is formed in a hollow cylindrical shape in a metal sheet such as stainless steel, and extends vertically from the top surface (defined by the closed end 215) of the furnace base 200. For example, a decorative cover 301 may be sleeved on an end of the furnace neck 300 contacting the furnace base 200. The closed end 215 of the hob 200 and the contact end of the furnace neck 300 can be connected together, for example, by means of fasteners such as screws or bolts, while the trim cover 301 can be used to cover these fasteners for connection for aesthetic and decorative purposes. The trim cover 301 is provided in such a way as to gradually converge from the side close to the hob 200 towards the side remote from the hob 200, so as to ensure complete covering of those fasteners for connection.

Further, a gas conduit 320 is penetrated in the hollow interior of the furnace neck 300. One end of the gas guide 320 protrudes into the inner space 210a of the hob 200 and is provided with a gas joint 310. The gas joint 310 is configured to be connectable with a gas canister loaded into the inner space 210a so that gas in the gas canister can be delivered through the gas conduit 320.

A burner 350 is detachably attached to the other end of the neck 300 opposite to the base 200. For example, the burner 350 can be removably connected to the end of the neck 300 via suitable fastening means, such as screws, bolts, or the like. It should be apparent to those skilled in the art that the body of the burner 350 may also be made of a high temperature resistant metal, such as stainless steel. A gas igniter is mounted on the burner 350. For example, the gas igniter has an on-off valve 352 located within the burner 350 and a knob 351 located on the outer surface of the burner 350 and accessible by the user. The on-off valve 352 is configured to be connected within the burner 350 to an end of the gas conduit 320 opposite the burner base 200, and the knob 351 is operatively connected to the on-off valve 352, such that by pressing and/or rotating the knob 351, gas delivered via the gas conduit 320 can be ignited by a spark generated by an ignition device (not shown) cooperating with the on-off valve 352. It should be clear to those skilled in the art that any suitable form of ignition switch may be suitable for the on-off valve 352 of the present application.

Further, the heat generator 400 is mounted to the burner 350 opposite to the neck 300 in the longitudinal direction. As shown in fig. 2E and 5B, the heater 400 includes a heat-radiating mesh body 410, a heater seat 420 receiving the heat-radiating mesh body 410, and an end cap 411 covering a top end of the heat-radiating mesh body 410. The heat dissipating mesh body 410 may be formed by winding a high temperature resistant metal sheet having a plurality of perforations, such as a stainless steel sheet, into a hollow cylindrical shape, for example. In a preferred embodiment, the metal sheet of the heat dissipating mesh body 410 may be formed with a plurality of perforations distributed as densely as possible. The heater seat 420 is also formed substantially of a high temperature resistant metal sheet, such as a stainless steel sheet, into a hollow shape with a large open end to receive a portion of the heat dissipating mesh body 410; and a small open end to be detachably connected with the burner 350. For example, the connection of the heater socket 420 and the heat radiating mesh body 410, and/or the connection of the heater socket 420 and the burner 350 can be achieved by providing aligned through holes therebetween and then by means of suitable fastening means such as screws or bolts. Unlike the heat dissipating mesh 410, although the heater socket 420 may be provided with the through holes, the number and distribution density of the through holes are significantly less than those of the heat dissipating mesh 410. Further, the end cap 411 is configured to be able to cover an open end of the cylindrical mesh body 410 opposite to the burner 350. End cap 411 is formed from a high temperature resistant metal sheet, such as a stainless steel sheet. The end cap 411 has no other perforations except for a few mounting holes 410a (three are shown). The end cap 411 can be connected to the cylindrical mesh body 410 by means of suitable fastening means such as screws or bolts. Thus, when the heater 400 is assembled in place, the end cap 411 constitutes a closed end of the heater 400, the heater socket 420 constitutes an open end of the heater 400, and the mesh body 410 together therewith encloses a hollow interior space of the heater 400.

With further reference to fig. 2E, a combustion cooktop 353 may be installed in the hollow interior of the heat generator 400. The combustion hob 353 may be provided as part of the burner 350. For example, the combustion cooktop 353 has a connection 353a that can be connected to the on-off valve 352. The combustion hob 353 is configured to enable a flame to be generated within the hollow interior space of the heat generator 400 by means of the gas delivered through the gas conduit 320 in case of a spark generated due to the action of the switching valve 352. In this way, heat generated by the flame can radiate radially outward through the perforations of the heat dissipating mesh body 410. Since the top end, i.e. the closed end, of the heat generator 400 is covered by the end cap 411, heat propagation vertically upwards is avoided as much as possible, thereby ensuring more heat radiating radially outwards, thereby providing a heat source around the outdoor heating furnace 100 in as efficient a manner as possible.

The base 200, neck 300, head 350, and heat emitter 400 are longitudinally sized such that when they are assembled and stand on the ground, the height of the heat emitter 400 from the ground is generally in the range of 1.5 meters to 2.5 meters. In an alternative embodiment, the gas conduit 320 may be a dedicated gas conduit covered with a stainless steel braid, for example, so that the furnace neck 300 may be in the form of a telescopic sleeve with a length capable of being telescopically adjusted and fixed, so that even after the outdoor heating furnace 100 is assembled and erected on the ground, the height of the heater 400 can be correspondingly adjusted by adjusting the length of the furnace neck 300, thereby adapting to the heating requirements of people with different heights or the environment.

As shown in fig. 2E, in the assembled outdoor heating furnace 100, the furnace cover 500 is disposed above the heat generator 400. The main function of the cover 500 is to block heat emitted from the heater 400 from being dissipated upward and to guide the heat radially toward the surroundings of the outdoor heating furnace 100, thereby helping the temperature around the outdoor heating furnace 100 to be raised as quickly as possible while maximizing the use of energy generated from gas to warm people around the outdoor heating furnace 100.

As further shown in fig. 2C, the furnace lid 500 generally takes the form of a disk, thereby allowing heat to be distributed evenly around. Further, the diameter of the outermost periphery of the substantially disk-shaped furnace cover 500 is larger than the maximum diameter dimension of the furnace base 200. In order to facilitate the storage and boxing of the furnace cover 500 for transportation, the furnace cover 500 is preferably designed to be split. For example, the furnace lid 500 is designed to include a central disk section 510 and a plurality (e.g., four are shown) of sector sections 520. A portion of the outer edge of the central disk section 510 coincides with the inner edge of each sector section 520. These segments may be detachably assembled together, for example, via suitable means such as screws, mortise and tenon fit, etc., to form the furnace lid 500. Mounting holes 510a are formed around the center of the furnace cover 500, in particular, in the central disk section 510 in the same number as the mounting holes 410a in the end cover 411. When assembled, the mounting holes 510a, 410a may be aligned with respect to each other to penetrate and fix the corresponding fixing member 550. For example, each of the fixing members 550 may be a screw member having threads at both ends thereof, so that threads are also formed in the corresponding mounting hole, so that the fixing members can fix the cover 500 with respect to the end cap 411 of the heater 400 by means of screw. To ensure that the heat is directed radially as desired, the cover 500 is formed in a manner that generally tapers from side to side. In this embodiment, after the outdoor heating furnace 100 is assembled and erected in place, the furnace cover 500 is gradually contracted from below toward above, thereby achieving the effect of collecting heat as much as possible, and the heat is spread radially toward the periphery only uniformly. It should be clear to those skilled in the art that the number of the fixing member 550 and the mounting hole 410a may be more, less, or even one.

In order to avoid excessive heat diffusion toward the upper side, the fixing members 550 are designed such that an air gap exists between the end cap 411 of the heat generator 400 and the cover 500 when the cover 500 is fixed in position relative to the heat generator 400 via them. Since air is a poor conductor of heat, it is possible to avoid as much as possible that heat is transferred to the furnace cover 500 by conduction and dissipated.

In use, a flame generated via the combustion gases will be present in the hollow interior space of the heat generator 400. Therefore, in order to ensure sufficient air to enter the hollow inner space of the heat generator 400, and to avoid accidents such as excessive carbon monoxide emission due to incomplete combustion of the combustion gas, a plurality of slits 412 extending in the circumferential direction are provided at the area of the end cover 411 of the heat-radiating mesh body 410. The slots 412 are circumferentially spaced from one another. For example, the slits 412 may be formed in the heat dissipating mesh body 410 itself. Alternatively, they may be intentionally designed vacant areas at the connection between the heat dissipating mesh body 410 and the end cap 411. In addition, a plurality of openings spaced apart from each other are also formed in a portion of the heater holder 420 adjacent to the burner 350 for supplying fresh air into the hollow inner space of the heater 400.

According to an alternative embodiment of the present application, the surrounding area of the furnace cover 500, e.g. each sector 520, may also be formed with a radial wave shape, so that heat may be better conducted radially outwards.

According to an embodiment of the present application, the design in which the heat generator 400 capable of generating a flame and the fire base 200 for storing a gas canister are spaced apart from each other (e.g., at least via the fire neck 300) enables the gas source to be spaced apart from the flame by a sufficient safety distance, so that the fire base 200 does not abnormally increase in temperature due to heat generated from the flame and thus pose a danger during use of the outdoor heating stove 100.

Fig. 3 schematically shows an outdoor heating furnace 110 according to another embodiment of the present application. As shown, the outdoor heating furnace 110 includes a burner base 200, a burner 300, a burner 350, a heater 400, and a furnace cover 500. Those features in fig. 3 which use the same reference numerals as in fig. 1 to 2E and 5B may refer to the description of the embodiment and the related modifications as described above, and will not be described in detail herein.

According to the embodiment shown in fig. 3, a deflector 600 is mounted on the heater 400 of the outdoor heating furnace 110, in particular on the outer surface of the heat dissipating mesh body 410 thereof. As shown in fig. 6, the deflector 600 can be formed in an annular, in particular circular, manner. The inner diameter of the annular deflector 600 is set to be slightly larger than the outer diameter of the heat radiating mesh body 410 so that the heat radiating mesh body 410 can be inserted into the central opening of the deflector 600 in the longitudinal direction. The deflector 600 functions to further direct the heat emitted from the heat-dissipating mesh body 410 toward the surroundings of the outdoor heating furnace 110. Because the deflector 600 is closer to the source of heat generation (flame) than the furnace lid 500, the provision of the deflector 600 will result in a more radial heat conduction effect.

As shown in fig. 5B, a plurality of supporting members 440 may be optionally disposed on the outer surface of the heat dissipating network 410, for example, the supporting members 440 may be welded to the heat dissipating network 410 or fixed to the heat dissipating network 410 by using screws or other suitable fastening devices. The support members 440 are located on the heat dissipating mesh body 410 generally in a (imaginary) plane perpendicular to the longitudinal axis of the heat dissipating mesh body 410, and the support members 440 are circumferentially spaced equidistant from each other. Thus, when the annular deflector 600 as shown in fig. 6 is fitted over the heat dissipating mesh body 410 and the outdoor heating stove 110 is erected in place as shown in fig. 3, these supports 440 are sufficient to support the annular deflector 600 near the edge of the central hole of the annular deflector 600.

The annular deflector 600 has an outer diameter smaller than the furnace lid 500. In a preferred embodiment, deflector 600 is designed to be non-planar. When the outdoor heating furnace 110 is in an upright state, for example, as viewed in the direction of gravity, the deflector 600 gradually expands downward from the edge of the central hole thereof toward the outer periphery. Such a design may further prevent heat generated by the flame from propagating upward after exiting the perforated outer surface of heat dissipating mesh body 410, facilitating radial outward diffusion.

Fig. 4 schematically shows an outdoor heating furnace 120 according to another embodiment of the present application. As shown, the outdoor heating furnace 120 includes a burner base 200, a burner 300, a burner 350, a heater 400, and a furnace cover 500. Features in fig. 4 that use the same reference numerals as in fig. 1 to 2E, 3 and 5B may be referred to the description of the above-described embodiment and related modifications, and will not be described in detail here.

Referring to fig. 4 and 5A, the outdoor heating furnace 120 further includes a first deflector 610 and a second deflector 620. The first deflector 610 and the second deflector 620 can be formed in a similar manner to the deflector 600 in the embodiment shown in fig. 3, but the outer diameter of the first deflector 610 is larger than the outer diameter of the second deflector 620. Further, the first deflector 610 is disposed on the heat dissipating mesh body 410 of the heater 400 of the outdoor heating furnace 120 to be longitudinally spaced apart from the second deflector 620, and the second deflector 620 is closer to the burner 350 than the first deflector 610. The two deflector designs can further facilitate heat spreading radially around from the heat dissipating mesh 410 and prevent heat from spreading upward (toward the furnace lid 500). Accordingly, the energy utilization efficiency of the outdoor heating furnace 120 is improved.

Fig. 7A is a top view schematically illustrating the second deflector 620. It will be clear to the person skilled in the art that the first deflector 610 can be arranged in the same way as the deflector 600 already described. The first deflector 610 and the second deflector 620 may have central bores of the same inner diameter, but with a larger outer diameter. Thus, the deflector shown in fig. 7A can represent either of the first deflector 610 and the second deflector 620, without the difference in outer diameter dimensions.

Fig. 7B schematically illustrates a heat dissipating mesh 410 that can be used with the deflector shown in fig. 7A. A plurality of support members 440 are disposed on the outer surface of the heat dissipating network 410. for example, the support members 440 may be welded to the heat dissipating network 410 or fixed to the heat dissipating network 410 by screws or other suitable fastening devices. The support members 440 are located on the heat dissipating mesh body 410 generally in a (imaginary) plane perpendicular to the longitudinal axis of the heat dissipating mesh body 410, and the support members 440 are circumferentially equally spaced from each other.

In addition, a plurality of additional support members 450 are provided on the outer surface of the heat dissipating mesh body 410, for example, the additional support members 450 may be welded to the heat dissipating mesh body 410 or fixed to the heat dissipating mesh body 410 by using other suitable fastening means such as screws. The additional support members 450 are located on the heat dissipating mesh body 410 generally in a (imaginary) plane perpendicular to the longitudinal axis of the heat dissipating mesh body 410, and the additional support members 450 are circumferentially spaced equidistant from each other. The additional support features 450 are longitudinally spaced from the plane in which the support features 440 are located, with each support feature 450 circumferentially offset from each support feature 440, but the circumferential spacing between the support features 450 may be equal to the circumferential spacing between the support features 440. That is, there is no longitudinal alignment of any one support 450 with any one support 440.

The shape of each bearing member 440 or 450 may be arbitrarily formed as long as it can have a certain extension in the radial direction. For example, in the illustrated embodiment, each support member is bent from an L-shaped sheet of metal, with one wing of the L-shape being secured to the outer surface of heat dissipating mesh body 410 and the other wing extending radially outward.

In addition, as shown in fig. 7A, a groove 460, which is positioned to be matched with each supporting member 440 or each supporting member 450, is formed at the edge of the central hole of the second deflector 620. The clearance of each recess 460 is sized to be just as large as or slightly larger than the radially outwardly extending flanks of the L-shaped support members secured to the outer surface of heat dissipating mesh body 410. For example, the number of grooves 460 may be the same as the number of supports 440 or 450. Taking the example of the second deflector 620 mounted in place closer to the burner 350, when mounting, the second deflector 620 is first slipped onto the heat dissipating mesh body 410 from the side of the heat dissipating mesh body 410 (e.g., the side away from the burner 350) while circumferentially aligning the grooves 460 of the second deflector 620 with the supports 450. The second deflector 620 may overlap the support members 440 after it has passed each support member 450 because the recess 460 is now longitudinally misaligned with the support member 440. The first deflector 610 may then be snapped onto the support 450.

It will be clear to the person skilled in the art that the manner of mounting of the deflectors shown in the figures is merely illustrative and not restrictive. For example, in an alternative embodiment, the tabs may be welded directly near the edge of the central hole of the deflector and the deflector may be secured to the outer surface of the heat dissipating mesh body 410 by screwing. Furthermore, the deflector may also be designed in the shape of a non-continuous circular ring, for example, in alternative embodiments, a plurality of fan-shaped deflectors may also be arranged on the outer surface of the heat dissipating mesh body 410, spaced apart from each other in the longitudinal direction and/or in the circumferential direction.

It will be clear to a person skilled in the art that the heat dissipating mesh body 410 of the outdoor heating stove may be provided with more (e.g. 3 or more) deflectors similar to those described above, which deflectors should be arranged with an outer diameter that decreases from the deflector furthest from the burner 350 towards the deflector closest to the burner 350.

Although specific embodiments of the present application have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the application. Further, it should be clear to those skilled in the art that the various embodiments described in this specification can be used in combination with each other. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present application.
