Definitions

  • the present invention generally relates to an enclosure structure of a gas water heater, and in particular to an water heater enclosure having a readily-detachable front panel for frequent change of outside appearance in an economic manner.
  • a gas water heater comprises a base plate mounted to a vertical fixed surface, such as a wall, and a front cover mounted to the base plate.
  • the front cover comprises a front panel having a circumference from which side panels extends rearward to form a casing having an open rear side, which is attached and secured to the base plate to form an enclosure inside which a burning/heating assembly of the heater that is generally fixed to the base plate is accommodated for protection purposes.
  • Taiwan Patent Publication No. 326262 discloses an improvement over the previously discussed water heater structure by forming holes on opposite marginal portions in a top portion of the front cover at positioned close to a rear edges of the top portion.
  • a projection is formed on the base plate at a location corresponding to each hole of the front cover and each projection forms an inclined extension receivable in the hole to thereby attach the front cover to the base plate. As such, efficient assembling of the water heater can be realized.
  • the conventional designs of the water heater both comprises a front cover that is made as a single piece by die stamping and the front cover so made is then mounted to and shields the base plate.
  • the front cover plays a major role for the outside appearance of the water heater.
  • the conventional front cover as discussed previously, once made, has a fixed construction and configuration. New die or mold is required for differently-constructed or shaped front cover. This is not economically practical due to the great expense for making of new dies or molds, and consequently, to save cost, the water heater industry often employs the old design of front cover in new models of water heaters. This imposes an undesired constraint on selection and modification of the outside appearance of water heaters. Also, distinction between different models of water heater is hard to tell. Apparently, further improvement is still of a great need of the water heater industry.
  • the front cover is made as a single piece by stamping, the front cover that is comprised of a front panel and side panels extending from and substantially normal to the front panel occupies a great amount of space. This causes problems in manufacturing, storage, and transportation of the manufacturers of the front cover. Costs are thus increased.
  • the primary purpose of the present invention is to provide an enclosure structure that comprises a base plate mounted to a fixed vertical surface and a front panel opposite to the base plate and two side panels each forming channels extending along opposite edges thereof to receive corresponding edges of the base plate and the front panel.
  • a top cover board and a bottom board, each defining an air passage, are fixed to upper and lower ends of the assembly of the base plate, the front panel, and the side panels and fixed thereto by fasteners, such as bolts, to secure the front panel, the side panels, and the base plate together.
  • an enclosure of water heater constructed in accordance with a first embodiment of the present invention comprises two opposite side panels (10), which are substantially rectangular, having front and rear edges.
  • Each side panel (10) comprise a first, front channel (11), preferably aluminum-extruded, longitudinally extending along and integrally formed at the front edge thereof, and a second, rear channel (12), also preferably aluminum-extruded, longitudinally extending along and integrally formed at the rear edge thereof.
  • the first and second channels (11), (12) are opposite to each other.
  • a front panel (20) having a thickness substantially corresponding to the first channels (11) of the side panels (10) has opposite edges received in the first channels (11), respectively, with upper and lower edges of the front panel (20) substantially flush with upper and lower edges of the side panels (10), respectively.
  • the front panel (20) forms, at a central portion thereof, an observing window (21).
  • a base plate (30) having a thickness substantially corresponding to the second channels (12) of the side panels (11) has opposite edges received in the second channels (12) of the side panels (10) with upper and lower edges of the base plate (30) substantially preferably flush with the upper and lower edges of the side panels (10), respectively.
  • a top cover board (40) mates the upper edges of the two side panels (10), the front panel (20), and the base plate (30) and forms air an outlet hole (41) at a center thereof.
  • the top cover board (40) also defines through holes (42) corresponding in position to the threaded holes (14) of the side panels (10) for the extension of bolts (43) therethrough to engage the threaded holes (14) thereby securing the top cover board (40) to the side panels (10), the front panel (20), and the base plate (30).
  • a bottom cover board (50) mates the lower edges of the side panels (10), the front panel (20), and the base plate (30) and forms air an inlet hole (51) at a center thereof.
  • the bottom cover board (50) also defines through holes (52) corresponding in position to the threaded holes (14) of the side panels (10) for the extension of bolts (53) therethrough to engage the threaded holes (14) thereby securing the bottom cover board (50) to the side panels (10), the front panel (20), and the base plate (30).
  • the front panel (20), the base plate (30), and the side panels (10) can be readily assembled/disassembled by simply fitting the edges of the front panel (20) and the base plate (3 0) into the first and second channels (11), (12) of the side panels (10) and attaching the top cover board (40) and the bottom cover boards (50) to the upper and lower edges thereof with bolts to secure the side panels (10), the front panel (20), and the base plate (30) together.
  • the side panels (10), the front panel (20), the base plate (30), the top cover board (40), and the bottom cover board (50) can be made separately. This significantly improves the conventional manufacturing process that makes a front cover of water heater enclosure as a single piece with a single die.
  • each channel (11), (12) has an expanded inboard edge having opposite ends in which the threaded holes (14) that are originally formed in the central rib (13) are formed to engage bolts (43), (53) extending through holes (42), (52) defined in the top and bottom cover boards (40), (50) and corresponding in positions to the threaded holes (14) thereby securing the top and bottom cover boards (40), (50) to the upper and lower edges of the side panels (10) and the front panel (20) and the base plate (30).
  • Threaded holes (14) are defined in ends of both the expanded inboard edges of the channels (11), (12) and the rib (13) and corresponding through holes (42), (52) are defined in the top and bottom cover boards (40), (50) to receive bolts (43), (53) that engage the threaded holes (14) to thereby secure the side panels (10), the front panel (20), and the base plate (30) together.
  • the enclosure of the fourth embodiment is a modification of the first embodiment by replacing the side panels (10) of the first embodiment, which are flat in general, with curved plates and the top and bottom cover boards (40), (50) are contoured in accordance with the curves of the curved side panels of the present embodiment.
  • the top and bottom cover boards (40), (50) are attached to the side panels (10) by bolts extending through the holes (42), (52) of the top and bottom cover boards (40), (50) and engaging the threaded holes (14) of the side panels (10).
  • the instant embodiment is intended to demonstrate that the enclosure in accordance with the present invention can be easily modified in the outside appearance by simply replacing the side panels (10), the top cover board (40), and the bottom cover board (50) with counterparts of different shapes. Consequently, the overall configuration or shape of the water heater can be made different to quite an extent. In addition, the costs for changing the side panels and the top and bottom cover boards, as well as the front panel and the base plate, are certainly much lower than replacing different stamping dies.
  • each channel (11), (12) has an expanded inboard edge having opposite ends in which the threaded holes (14) that are originally formed in the central rib (13) are formed to engage bolts (43), (53) extending through holes (42), (52) defined in the top and bottom cover boards (40), (50) and corresponding in positions to the threaded holes (14) thereby securing the top and bottom cover boards (40), (50) to the upper and lower edges of the side panels (10) and the front panel (20) and the base plate (30).
  • Threaded holes (14) are defined in ends of both the expanded inboard edges of the channels (11), (12) and the rib (13) and corresponding through holes (42), (52) are defined in the top and bottom cover boards (40), (50) to receive bolts (43), (53) that engage the threaded holes (14) to thereby secure the side panels (10), the front panel (20), and the base plate (30) together.
