Description

Technical Field

[0001] The utility model relates to a gas stove accessory, in particular to a bottom shell for a gas stove. Background Art

[0002] In existing gas furnace designs, the installation of the furnace bottom shell usually relies on pre-cut mounting holes. The dimensions of these mounting holes must be highly compatible with the dimensions of the bottom shell to ensure proper installation and stability of the gas furnace. However, the existing technology has obvious shortcomings during the installation process, specifically:

[0003] 1. The installation of existing gas stove bottom shells requires extremely precise hole dimensions. If the installation hole is too small, the gas stove bottom shell will not fit, requiring re-machining the hole, increasing installation complexity and cost. If the hole is slightly larger, the bottom shell will fit, but the mismatch may leave a gap between the bottom shell and the hole, resulting in a loose fit. In this case, the stove may wobble or shift during use, affecting safety.

[0004] 2. In existing gas stove designs, when the mounting hole is too large, there can be gaps between the bottom shell and the opening in the left-right or front-to-back direction, resulting in an insecure installation of the stove. This looseness not only affects the proper function of the stove but can also cause the stove to move during use, creating a dangerous situation. For example, the stove may shift during use due to thermal expansion or external forces, increasing the risk of gas leaks or other safety hazards.

[0005] 3. Existing technology requires stringent installation hole dimensions, requiring installers to be extremely precise during installation. Otherwise, multiple adjustments and adjustments may be necessary, increasing installation time and labor costs. Furthermore, any deviations in the holes can complicate installation of the furnace bottom shell. In severe cases, the bottom shell may need to be remade or the hole dimensions adjusted, impacting both construction progress and installation quality.

[0006] 4. Existing gas furnace bottom shell designs are too simplistic and unable to accommodate minor variations in mounting hole dimensions. Because various installation environments and construction conditions can lead to variations in mounting hole dimensions, existing designs lack the flexibility to adjust the bottom shell installation method. This creates high requirements for hole dimensions and limits the adaptability and installation convenience of gas furnaces in different environments.

[0007] In summary, existing technologies face challenges in gas furnace bottom shell installation, including strict requirements for opening dimensions, unstable installation, and difficulty adapting to openings of varying sizes. These deficiencies not only increase installation difficulty but also pose potential safety risks. Therefore, further improvements are necessary. Utility Model Content

[0008] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a bottom shell for a gas stove which has a simple structure, is easy to use, simplifies the installation process and improves the installation efficiency.

[0009] The purpose of the utility model is achieved by the following method: a bottom shell for a gas stove, comprising a bottom plate, the middle portion of the bottom plate being recessed downward to form a receiving cavity, a plurality of width adjustment holes being provided on the left and right sides of the bottom plate, a width adjustment plate being bent downward being provided in the width adjustment holes, and the plurality of width adjustment holes being arranged to extend in the width direction;

[0010] A plurality of depth adjustment holes are provided on the rear side of the chassis, and a depth adjustment plate that can be bent downward is provided in the depth adjustment holes; and the plurality of depth adjustment holes are arranged to extend in the depth direction.

[0011] Furthermore: a plurality of reinforcing ribs are stamped on the chassis, and the reinforcing ribs are protruded toward the front of the chassis.

[0012] Furthermore: the width adjustment holes are symmetrically arranged on both sides of the chassis.

[0013] Furthermore, the width adjustment hole is arranged in a long waist shape, and the width adjustment hole is extended in the front-back direction.

[0014] Furthermore, the width adjustment plate is connected to one of the short sides of the width adjustment hole, and the top and left and right sides thereof are suspended.

[0015] Furthermore, the depth adjustment hole is arranged in a long waist shape, and the depth adjustment hole is extended in the left and right directions.

[0016] Furthermore: the depth adjustment plate is connected to one of the short sides of the depth adjustment hole, and the top and left and right sides thereof are suspended.

[0017] Furthermore: an air inlet groove is provided on the back side of the accommodating cavity, and the air inlet groove runs through the accommodating cavity.

[0018] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0019] 2. The present invention features width adjustment plates on the left and right sides of the bottom shell, and a depth adjustment plate on the rear side. These plates, nestled within the width and depth adjustment holes, can be bent and snapped into the installation openings as needed during installation. This design eliminates the need for strict cabinet opening dimensions and effectively accommodates situations where the opening is too large or too small. Even if the opening is slightly larger, the bending and snapping of the adjustment plates fills the gap between the bottom shell and the opening, ensuring stable installation. Furthermore, if the opening is slightly smaller, the adjustment plates can be adjusted adaptively to ensure smooth installation of the bottom shell.

[0020] 3. Traditional gas stove bottom shells have very strict requirements for the size of the opening during installation. If the opening is too large, a gap may be left between the bottom shell and the opening, resulting in an unstable installation. The gas stove is prone to movement or shaking during use, affecting its safety. The curved design of the width adjustment plate and the depth adjustment plate of the utility model ensures that the bottom shell forms a tight fit with the opening after installation, firmly locking the edge of the opening and eliminating the problem of left-right or front-back movement of the stove. This not only improves the installation security of the gas stove, but also effectively prevents the risk of displacement caused by external forces or thermal expansion during use, ensuring safe use.

[0021] 4. Because the present invention's snap-on design of the adjustment plate allows for flexible adaptation to the installation hole size, installers no longer need to precisely measure or strictly define the hole size during actual operation, reducing installation tolerances. This design simplifies the installation process, reduces construction difficulty, and avoids installation failures or rework caused by inaccurate hole size. Compared to existing technologies that rely heavily on hole size, the present invention significantly improves the efficiency and convenience of gas furnace installation.

[0022] 5. The width and depth adjustment plates of this utility model allow the gas stove bottom shell to adapt to cabinet openings of varying specifications and sizes. This means the gas stove can be used in a variety of installation environments, eliminating the need for specialized design and processing for specific opening sizes. This significantly increases the stove's applicability and versatility. Whether constructing new cabinets or renovating existing ones, the adjustment function of this utility model allows for rapid adaptation, reducing user dependence on the installation environment and improving the product's market adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 4 For this utility model Figure 1 A magnified view of the structure of part A. DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings. A gas stove bottom shell comprises a bottom plate 1, the center of the bottom plate 1 being recessed downward to form a receiving cavity 2, a plurality of width adjustment holes 3 being provided on the left and right sides of the bottom plate 1, each of which has a downwardly bendable width adjustment plate 4 disposed therein, the plurality of width adjustment holes 3 extending in the width direction;

[0026] The rear side of the chassis 1 is provided with a plurality of depth adjustment holes 5 , and a depth adjustment plate 6 that can be bent downward is provided in the depth adjustment holes 5 ; the plurality of depth adjustment holes 5 are arranged to extend in the depth direction.

[0027] In one embodiment, a plurality of reinforcing ribs 7 are stamped on the chassis 1 , and the reinforcing ribs 7 are protruding toward the front side of the chassis 1 .

[0028] In one embodiment, the width adjustment holes 3 are symmetrically arranged on both sides of the chassis 1 .

[0029] In one embodiment, the width adjustment hole 3 is in a long waist shape and extends in the front-to-back direction.

[0030] In one embodiment, the width adjustment plate 4 is connected to one of the short sides of the width adjustment hole 3, and the top and left and right sides thereof are suspended.

[0031] In one embodiment, the depth adjustment hole 5 is in a long waist shape, and the depth adjustment hole 5 is extended in the left and right directions.

[0032] In one embodiment, the depth adjustment plate 6 is connected to one of the short sides of the depth adjustment hole 5 , and the top and left and right sides thereof are suspended.

[0033] In one embodiment, an air inlet groove 8 is provided on the back side of the accommodating cavity 2 , and the air inlet groove 8 is provided through the accommodating cavity 2 .

[0034] Working Principle: The chassis 1 of this utility model has a downwardly recessed center portion forming a chamber 2 for accommodating the main components of the gas stove. Width adjustment holes 3 are located on the left and right sides of the chassis, while depth adjustment holes 5 are located on the rear side. These holes are respectively fitted with width adjustment plates 4 and depth adjustment plates 6. These plates bend downward and fit into the mounting holes, creating a stable mounting structure.

[0035] During installation, if the dimensions of the cabinet or stove platform opening don't exactly match the bottom shell, the width and depth adjustment plates play a crucial role. If the mounting hole is slightly larger, the adjustment plates can be bent downward and snapped onto the edges of the opening. With this tight fit, the bottom shell is securely installed. This design ensures that even if the hole is slightly larger, the adjustment plates can fill the gap between the bottom shell and the opening, ensuring a secure fit. If the hole is slightly smaller, installation can be achieved by simply bending the adjustment plates to match the hole.

[0036] The chassis is designed with several reinforcing ribs 7, formed through a stamping process and protruding toward the front of the chassis, adding strength. During installation, these ribs ensure that the bottom shell does not deform when subjected to weight or external forces, further enhancing the lifespan and stability of the gas stove. Furthermore, the central cavity 2 in the chassis not only accommodates the gas stove's internal components but also provides sufficient structural support during installation, preventing displacement or shaking after installation.

[0037] The multi-hole structure of the width and depth adjustment holes is arranged in a specific pattern: the width adjustment holes 3 are arranged symmetrically along the left and right sides, and the depth adjustment holes 5 are arranged along the front-to-back direction. This design allows the adjustment plate to be adjusted in different directions to accommodate mounting holes of varying sizes. When the adjustment plate is bent, its top and left and right sides snap into place with the edges of the opening, acting like a snap, preventing the gas stove bottom shell from moving left and right or front and back during use.

[0038] Compared to conventional technology, this design utilizes width and depth adjustment plates, eliminating the need for strict cabinet opening dimensions. This design significantly enhances installation flexibility. Whether the opening is too large or too small, the bending and snapping action of the adjustment plates ensures a tight and secure installation, resolving the issue of unstable installation caused by mismatched opening dimensions in existing technology.

[0039] The width and depth adjustment plates are bent and snapped into place around the edges of the opening, ensuring a tight fit between the bottom shell and the opening after installation, preventing side-to-side or front-to-back movement. This design ensures the gas stove remains stable during use, preventing movement due to vibration, thermal expansion, or external forces, thus enhancing safety.

[0040] Since the precise dimensions of the opening are no longer strictly required, installers can operate more conveniently during the construction process. This not only simplifies the installation process but also reduces installation failures and rework caused by dimensional errors. More importantly, the bottom shell structure of this utility model can accommodate openings of various sizes, expanding the applicability of gas furnaces.

[0041] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
