Problems solved by technology

[0004] The air intake hole of the current range hood is generally fixed relative to the stove, resulting in unsatisfactory smoking effect
And when the smoke is heavy, it is difficult to suck all the gas clean only by the fume collecting hood assembly, especially for the occasions where the smoke is relatively heavy, it is impossible to completely suck the fume away, resulting in a high concentration of cooking fume in the kitchen air. Environmental deterioration

Embodiment 1

[0101] Example 1: Single cavity structure

[0102] Such as Figure 1~13 As shown, an automatic telescopic range hood with a residual smoke collection function and a single cavity structure includes a housing 1, an air duct fixed in the housing 2, a fan assembly 3 for exhausting the air duct, and smoke extraction The smoke collecting hood assembly 4 is connected and positioned between the smoke collecting hood assembly 4 and the air duct 2 through a telescopic assembly 5.

[0103] reference figure 2 The housing 1 is composed of an upper housing 101, a housing middle plate 102, a housing main body 103, a housing bottom plate 104, and a housing back plate 100.

[0104] A ceiling fixing bracket 105 is installed on the top of the upper shell 101, and when a hanging fixing method is adopted, the range hood is fixed to the ceiling or roof wall of the room by the ceiling fixing bracket 105. A wall bracket 106 is installed on one side of the upper shell 101. When a wall-mounted fixing metho...

Embodiment 2

[0122] Example 2: Double cavity structure

[0123] Such as Figure 14-17 As shown, an automatic telescopic range hood with a residual smoke collection function and a dual-chamber structure differs from the technical solution disclosed in Embodiment 1 in:

[0124] The housing back plate 100 has a slightly different shape from that of the first embodiment, and is used for fixing the upper housing 101, the housing middle plate 102, the housing main body 103, and the housing bottom plate 104, and other functions are similar.

[0125] In this embodiment, the smoke collecting hood assembly 4, the air duct 2 and the telescopic assembly 5 are all symmetrically arranged in two groups.

[0126] In addition, the middle of the housing bottom plate 104 is provided with two avoidance holes for avoiding two telescopic tube assemblies. Two mounting seats 109 are installed on the inner side wall of the avoidance hole, and the outer side wall is provided with a corresponding fume hood assembly 4 The pr...

Abstract

The invention discloses an automatic telescopic range hood with a residual fume collection function. The automatic telescopic range hood comprises an air duct, a draught fan assembly and a fume collecting hood assembly, the draught fan assembly extracts air from the air duct, and the fume collecting hood assembly communicates with an air inlet of the air duct. The automatic telescopic range hood further comprises residual fume collection openings communicating with the air inlet of the air duct at the same time. The air duct and the fume collecting hood assembly are connected and positioned through a telescopic assembly. The telescopic assembly comprises a corrugated pipe, a telescopic pipe component and a driving mechanism, wherein the fume collecting hood assembly and the inlet of the air duct are sealed and butted through the corrugated pipe, the telescopic pipe component can drive the fume collecting hood assembly and the corrugated pipe to synchronously stretch out and draw back, and the driving mechanism drives the telescopic assembly to stretch out and draw back. Through the arrangement of the residual fume collection openings, it is further ensured that all the fume can be pumped and removed; meanwhile, the telescopic assembly is arranged and combined, so the height of the fume collecting hood assembly can be adjusted according to the need, and it is guaranteed that residual fume generated in the whole process, before and after adjustment and operation, of the fume collecting hood assembly is rapidly pumped away.

Description

Technical field [0001] The invention belongs to the technical field of range hood design, in particular to an automatic telescopic range hood with a residual smoke collection function. Background technique [0002] The range hood, also known as the range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the stove and can quickly suck out the exhaust gas from the stove and the oil fume generated during the cooking process and discharge it to the outdoors, reducing pollution and purifying the air . [0003] Existing range hoods mainly include a fume hood assembly, an air duct (including air ducts), and a fan assembly; the fume hood assembly is provided with an air inlet, and the opening of the air inlet faces the stove. A net cover is usually installed on the air intake. When the range hood is working, the wind wheel rotates at a high speed to form a negative pressure zone in a certain space above the stove, and the indoor fume gas is sucked i...
