Patent Grant
10371414
The disclosure herein relates to a burner system of a furnace, which may be, for example, included in a heating, venting and air conditioning (HVAC) system. More specifically, burner holders and cartridges are described that are configured to retain and support one or more burners. Support assemblies of the holders and cartridges may allow one or more burners to be removed and installed relatively easily from a burner system.
A furnace may be found in a HVAC system. The furnace typically includes a burner system, one or more heat exchangers, and a blower. The burner system can be configured to combust gas to generate heat, which can be used to, for example, heat air. Typically, the burner system may include one or more burners, a manifold, a gas valve and a support assembly to hold these components. These components are secured to the support assembly, for example by brackets and fasteners. The burners are a serviceable item and may need to be cleaned on a regular basis. However, the brackets and fasteners may make it difficult to remove and install the burners.
Embodiments as disclosed herein are directed to burner holders and burner cartridges that may be used in a burner system, and which may include a support assembly configured to support at least one burner and a manifold.
In some embodiments, the manifold may be attached to the support assembly. With the burner holders and/or cartridges disclosed herein a burner may be removed or installed without dissembling the manifold from the support assembly.
In some embodiments, the support assembly may include a burner holder that includes a cutout region configured to accommodate a burner. The cutout region may include a first ear and a second ear to engage the burner. At least one of the first and second ears may have an angled portion, which is configured so that when the burner is twisted from an operational position to a disengaging position, the burner can have a clearance in the cutout region and be removed.
In some embodiments, the support assembly may include a locking member to close an opening of the cutout region to hold the burner in place. In some embodiments, the support assembly may be attached to the manifold of the burner by an orifice, which may function as a fastener.
In some embodiments, the burner holder may include a plurality of cutout regions, and profiles of the neighboring cutout regions are mirrored.
In some embodiments, the manifold is attached to the supporting assembly by an orifice.
Other features and aspects of the systems, methods, and control concepts will become apparent by consideration of the following detailed description and accompanying drawings.
Reference is now made to the drawings in which like reference numbers represent corresponding parts throughout.
A furnace may include a burner system having one or more burners, a manifold, a gas valve, and a supporting structure to hold these components. Generally, the one or more burners may be fixed in place, for example, with brackets and fasteners. An end of the burners may also be fixed, for example, by attaching the end of the burners to the corresponding gas orifice. When brackets and fasteners are used as the primary ways of attaching the burners, a service technician may need to remove the manifold in order to remove the burners for service and/or maintenance. Removing the manifold may require a gas line to be broken and removed, which can increase a risk of the gas line not being sealed properly and/or take a relatively long period of time.
Burner holders and cartridges of a furnace are described herein, and which include a support assembly and a manifold. The support assembly is configured to support one or more burners. In one example, the support assembly may include a burner holder with a cutout region, which may allow a burner to be moved between an operational position and a disengaging position by twisting the burner. The cutout region can allow the one or more burners to be removed or installed relatively easily, without the need of removing the manifold from the support assembly. In another example, the support assembly is constructed as a cartridge.
With the holders and/or cartridges herein, the manifold can be attached to the support assembly by, for example, using one or more orifices as fasteners.
References are made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration of the embodiments that may be practiced. It is to be understood that the terms used herein are for the purpose of describing the figures and embodiments and should not be regarded as limiting the scope.
The burner system 110 includes one or more burners 112, a valve 114, a manifold 116 and a support assembly 118. The burner 110 is configured to combust gas to generate heat.
The support assembly 240 has a base portion 244. The burner 210 has a foot 213 that engages the base portion 244. As illustrated in
In an embodiment, the support assembly 240, its base portion 244, and the burner holder 242 may be arranged and constructed as a cartridge for multiple burners.
Referring to
Referring to
The first ear 245 has an angled portion 245a. In an disengaging position as illustrated in
As illustrated in
When the burner 210 is installed, the burner 210 can be positioned in the disengaging position first and then twisted into place. The angled portion 245a can help push the burner 210 into a desired position when the burner 210 is twisted.
Referring back to
Referring to
The embodiments as disclosed herein allow a plurality of burners 210 to be removed or installed individually, reducing the need to handle more than one burner 210 simultaneously, which may be helpful during the service or maintenance process.
Referring back to
In the illustrated embodiment, the locking member 260 is a bracket that closes the opening 249 of the cutout regions 243. This is exemplary; and the locking member 260 can have other suitable configurations that may help retain and lock the burners 210 in place. For example, in some embodiments, the locking member may include a plurality of pieces, each of which may be used to retain and lock one burner 210. The locking member 260 can have a profile to accommodate the burner 210 so that when the locking member 260 engages the burner holder 242, the burner 210 may be locked into a desired position (for example, centered relative to, for example, the orifice 232 as illustrated in
Referring to
The burner 210 can be moved in and out of the cutout region 243 by twisting the burner 210. The burner 210 can be removed and installed without detaching the manifold 230 from the support assembly 240. There is no need to remove the orifice 232 from the manifold 230. Referring to
It is to be appreciated that in some embodiments, the cutout region may not include the ears. As illustrated in
The embodiments of burner holders and cartridges as described herein include the manifold attached to the support assembly. For example, the burner cartridge can be attached to and removed from a structural component of the burner system as a single unit. During the burner removal and/or installation process, the burner cartridge can also be handled as one single unit, and where each burner may be individually handled. There is no need to dissemble the manifold from the support assembly. These features simplify service and/or handling of the burner system in the furnace.
Aspect 1. A burner system, comprising:
a burner cartridge including a supporting assembly and a manifold; and
at least one burner;
wherein the supporting assembly includes a burner holder or support and a locking member; the burner support has at least one cutout region configured to accommodate the at least one burner;
the at least one cutout region has an opening, a first ear and a second ear;
the burner has an operational position and a disengaging position;
when the burner is in the operational position, the burner is configured to engage the first ear and second ear, and when the burner is in the disengaging, the burner has a clearance with respect to the first ear and the second ear; and
the locking member is configured to close the opening, and a profile of the locking member is configured to lock the burner into a desired position.
Aspect 2. The burner system of aspect 1, further comprising:
an orifice; wherein the support assembly is attached to the manifold by the orifice.
With regard to the foregoing description, it is to be understood that changes may be made in detail, without departing from the scope of the present invention. It is intended that the specification and depicted embodiments are to be considered exemplary only, with a true scope and spirit of the invention being indicated by the broad meaning of the claims.
