A main unit frame module structure for under-mounted air ducts in integrated stoves

Abstract

This invention discloses a main unit frame module structure for a bottom-mounted air duct in an integrated stove, including a U-shaped enclosure, a fan module, an exhaust module, and a smoke exhaust pipe assembly. The U-shaped enclosure includes side panels and a rear panel. A front bottom plate and a rear crossbeam are provided at the bottom of the U-shaped enclosure. An exhaust adapter is provided at the top rear side of the fan module, and a smoke exhaust adapter is provided on one side of the fan module. Both side panels have pre-drilled holes. The U-shaped enclosure is integrally molded, simplifying the production process. The front bottom plate and rear crossbeam support the fan module. The fan module is located at the bottom of the integrated stove rather than vertically mounted at the back, increasing the lateral space for other modules and allowing for larger functional modules. Both side panels have pre-drilled holes for connecting to the smoke exhaust pipe assembly, meeting the actual needs of different users for different airflow directions and making the installation of the integrated stove more flexible. Empty pre-drilled holes are sealed with pre-drilled baffles to prevent external debris from entering the integrated stove.

Description

Technical Field

[0001] This invention relates to the field of integrated stove technology, and in particular to a main unit frame module structure for a bottom-mounted air duct in an integrated stove. Background Technology

[0002] Conventional integrated cooktops typically employ either a through-flow air outlet structure or a unidirectional straight exhaust structure. The through-flow air outlet structure of conventional integrated cooktops requires the exhaust direction to be predetermined at the factory, making it difficult to meet the actual installation needs of users who require both left and right exhaust. Therefore, this design has been improved. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies that make it difficult to meet the actual installation requirements of users with both left and right air outlets, by providing a new main unit frame module structure for integrated stoves with under-mounted air ducts.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] A main unit frame module structure for an integrated stove with a bottom-mounted air duct includes a U-shaped enclosure, a fan module, an exhaust module, and a smoke exhaust pipe assembly. The U-shaped enclosure includes two side panels and a rear panel. The rear panel connects the rear parts of the two side panels. A front bottom plate and a rear crossbeam are provided at the bottom of the U-shaped enclosure. The front bottom plate and the rear crossbeam connect the bottoms of the two side panels. The fan module is connected to the U-shaped enclosure via the front bottom plate and the rear crossbeam. An exhaust adapter is provided at the top rear side of the fan module. The bottom of the exhaust module is inserted into the exhaust adapter. A smoke exhaust adapter is provided on one side of the fan module. Each side panel has a reserved hole. The smoke exhaust adapter is connected to the smoke exhaust pipe assembly via one of the reserved holes, and the reserved hole on the other side panel is closed by a reserved baffle.

[0006] The U-shaped integrated panel simplifies the production process. The front base plate and rear crossbeam support the fan module, which is located at the bottom of the integrated cooktop rather than vertically at the back, increasing the lateral space for other modules and allowing for larger functional modules. Both side panels have pre-drilled holes for connecting to the exhaust pipe assembly, meeting the needs of different users for different airflow directions and making the installation of the integrated cooktop more flexible. Any missing pre-drilled holes are sealed with pre-drilled baffles to prevent external debris from entering the integrated cooktop.

[0007] Preferably, in the above-described main unit frame module structure for an integrated stove with a bottom-mounted air duct, the exhaust adapter includes an inner exhaust pipe and an exhaust pipe sealing ring. The exhaust pipe sealing ring is connected to the U-shaped enclosure plate by screws. The exhaust pipe assembly includes an outer exhaust pipe and a core rod. The exhaust pipe sealing ring connects the outer exhaust pipe and the inner exhaust pipe. The exhaust pipe sealing ring is provided with a locking hole. The outer exhaust pipe is provided with an elastic sleeve that passes through the locking hole. When the core rod is inserted into the elastic sleeve, the elastic sleeve is interference-fitted with the locking hole.

[0008] The exhaust pipe sealing ring is used to seal the joint between the external and internal exhaust pipes, preventing fumes from overflowing from the connection point. The internal exhaust pipe and the exhaust pipe sealing ring are pre-connected with screws. Then, the exhaust pipe sealing ring is aligned with the pre-drilled hole on the U-shaped panel and secured to the main unit with screws. After inserting the elastic sleeve into the locking hole, the mandrel is inserted into the elastic sleeve, causing it to expand outwards and interlock with the locking hole. In practical terms, simply inserting the elastic sleeve of the external exhaust pipe into the locking hole and then inserting the mandrel into the elastic sleeve completes the connection of the external exhaust pipe. This simple operation facilitates both the installation and disassembly of the external exhaust pipe.

[0009] Preferably, the above-described main unit frame module structure for a bottom-mounted air duct of an integrated stove includes a fan module comprising a negative pressure box, a front support plate, and an oil collection box. The front support plate is fixed to the lower surface of the front end of the negative pressure box, the bottom of the front support plate abuts against the front base plate, the lower surface of the rear of the negative pressure box abuts against the rear crossbeam, an oil collection clearance hole is provided in the middle of the front support plate, the oil collection box passes through the oil collection clearance hole, a negative pressure oil outlet is provided on the lower surface of the negative pressure box, the vertical projection of the negative pressure oil outlet is located in the opening of the oil collection box, and the oil collection box is placed on the front base plate.

[0010] The rear crossbeam and front base plate support the negative pressure box. The upper surface of the rear crossbeam is higher than the upper surface of the front base plate. The front support plate is designed to keep the negative pressure box balanced and also provides space for the oil collection box.

[0011] Preferably, in the above-described main unit frame module structure for an integrated stove with a bottom-mounted air duct, the rear crossbeam is provided with an oil collection groove, and the rear end of the oil collection box is inserted into the oil collection groove.

[0012] The oil collection trough is used to support the oil collection box, making it less likely to tip over when collecting oil.

[0013] Preferably, in the above-described main unit frame module structure for the under-mounted air duct of an integrated stove, the top of the exhaust adapter is provided with an exhaust flexible sealing ring.

[0014] The flexible sealing ring for exhaust can eliminate gaps and prevent oil fumes from escaping from the gap between the exhaust adapter and the exhaust module. Attached Figure Description
