Description

Technical Field

[0001] The present invention relates to the technical field of integrated stoves, and particularly to a lower horizontal type high-efficiency smoke exhaust integrated stove. Background Art

[0002] An integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, a gas stove, a disinfection cabinet, and a storage cabinet, and is currently favored by more and more families. With the progress of technology and the improvement of living standards, current integrated stoves have added components such as ovens and steamers, posing higher requirements for the space utilization rate inside the integrated stove. At the same time, as the requirements for user experience are getting higher and higher, people not only care about the air volume and noise of the integrated stove, but also increasingly attach importance to the smoke gathering effect of the integrated stove.

[0003] In actual use, when users stir-fry, the oil fume forms quickly, and the range hood cannot suck the oil fume into the air duct in time, resulting in serious oil fume escape.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present invention provides a horizontal high-efficiency smoke exhaust integrated stove, which has the following

[0015] Beneficial effects:

[0016] 1.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: Please refer to Figures 1-6 , a horizontal high-efficiency smoke exhaust integrated stove, including an integrated stove head 1, a main air duct 2 is fixedly installed at the rear side of the integrated stove head 1, L-shaped side air ducts 3 are symmetrically and fixedly installed on the left and right sides of the integrated stove head 1, the air outlets of the two L-shaped side air ducts 3 are communicated with the air outlet of the main air duct 2 through a four-way air duct 4, a detachable exhaust fan 5 is fixedly installed at the air outlet of the four-way air duct 4, the four-way air duct 4 includes three horizontal air inlets and one vertical air outlet, a three-way air duct 6 is horizontally rotatably installed in the four-way air duct 4, the three-way air duct 6 includes two horizontal air inlets and one vertical air outlet, and the air outlets of the four-way air duct 4 and the three-way air duct 6 are aligned and communicated. The three-way air duct 6 rotates horizontally in the four-way pipe 4 and is used to adjust the air outlet of the four-way air duct 4 to selectively communicate with the air outlets of the two L-shaped side air ducts 3 or the main air duct 2. A rotation adjustment assembly 7 for adjusting the horizontal rotation of the three-way air duct 6 is movably installed in the four-way air duct 4. A cubic storage cavity 8 is formed between the outer walls of the two L-shaped side air ducts 3, the main air duct 2, and the four-way air duct 4 and the bottom of the integrated stove head 1; by driving the three-way air duct 6 in the four-way air duct 4 to rotate horizontally by 90 degrees through the rotation adjustment assembly 7, the air outlet of the four-way air duct 4 can be selectively communicated with the air outlets of the two L-shaped side air ducts 3 or the air outlet of the main air duct 2, thereby changing the smoking air inlet position and the air inlet size relative to the integrated stove head 1 of the integrated stove, avoiding the situation that when the user stir-fries violently, the oil fume forms quickly and the range hood cannot suck the oil fume into the air duct in time, resulting in oil fume escaping. At the same time, by arranging an exhaust fan 5 at the air outlet of the four-way air duct 4 of the integrated stove, efficient smoke exhaust of different air ducts can be realized, achieving the effect of efficient smoke exhaust of different air ducts with a single exhaust fan; in addition, since both of the two L-shaped side air ducts 3 are right-angled structures and cooperate with the outer wall of the four-way air duct 4 and the bottom of the integrated stove head 1 to form a cubic storage cavity 8, the space utilization rate of the storage cavity 8 is greatly increased compared with the traditional circular pipe, further improving the practicability of the integrated stove.

[0028] Preferably, as Figure 4As shown in the figure, the rotation adjustment assembly 7 includes a turbine 71 and a worm 72. The turbine 71 is horizontally sleeved on the outer wall of the three-way air duct 6, and the worm 72 is rotatably installed in the four-way air duct 4 along the horizontal axis and meshes with the turbine 71. By rotating the worm 72, the worm 72 drives the turbine 71 and the three-way air duct 6 to horizontally rotate in the four-way air duct 4, thereby adjusting the selective connection between the air outlet of the four-way air duct 4 and the air outlets of the two L-shaped side air ducts 3 or the air outlet of the main air duct 2, and changing the position and size of the smoke intake opening of the integrated range hood relative to the integrated range hood head 1, so as to avoid the situation that the oil fume escapes because the oil fume forms too fast during the user's stir-frying and the range hood cannot suck the oil fume into the air duct in time.

[0029] It should be noted that in the above technical solution, the rotation adjustment assembly 7 uses the cooperation of the turbine 71 and the worm 72 to drive the three-way air duct 6 to horizontally rotate in the four-way air duct 4. Other horizontal rotation drive mechanisms can also be used, such as a drive motor cooperating with a gear transmission to drive the three-way air duct 6 to horizontally rotate in the four-way air duct 4, that is, as long as it is ensured that the three-way air duct 6 can horizontally rotate in the four-way air duct 4 and selectively communicate with the air outlets of the two L-shaped side air ducts 3 or the air outlet of the main air duct 2.

[0030] Preferably, as Figure 3 shown, by installing one or more combinations of a steam box, an oven, a microwave oven, a disinfection cabinet or a warming cabinet, etc. in the storage cavity 8, the integrated range hood is made to have multifunctional performance, and the practicability of the integrated range hood is further improved.

[0031] Embodiment 2: As Figure 8 shown, the difference from Embodiment 1 is only that the exhaust fan 5 adopts a double-inlet volute fan, and two air outlet covers 9 are symmetrically and fixedly installed on the main air duct 2 and behind the exhaust fan 5. The air outlet of the exhaust fan 5 is communicated with the air inlet of one of the air outlet covers 9, the upper air inlet of the exhaust fan 5 is communicated with the air outlet of the four-way air duct 4, and the lower air inlet of the exhaust fan 5 abuts against the outer wall of the main air duct 2 to form a seal. By disassembling the exhaust fan 5 from the main air duct 2 and installing it after a 180-degree flip, the air outlet of the exhaust fan 5 is selectively communicated with the air inlet of the other air outlet cover 9, that is, the effect of simply and conveniently switching the left and right smoke exhaust outlets of the integrated range hood is achieved without changing the smoke exhaust duct of the integrated range hood, and the practicability of the integrated range hood is further improved.

[0032] Embodiment 3: As Figures 7-8As shown, the difference from the second embodiment is only that the cross-section of the main air duct 2 is F-shaped. The main air duct 2 includes a duct body 21, a main air inlet 22, a first air outlet 23, and a second air outlet 24. The duct body 21 is fixedly installed at the rear side of the integrated stove head 1. A main air inlet 22 is provided on the side of the duct body 21 close to the integrated stove head 1 and above the integrated stove head 1. A first air outlet 23 is provided on the side of the duct body 21 close to the integrated stove head 1 and below the integrated stove head 1. The first air outlet 23 is communicated with the air inlet of the four-way air duct 4. The air outlet of the four-way air duct 4 is communicated with the upper air inlet of the exhaust fan 5. A second air outlet 24 is provided on the side of the duct body 21 close to the integrated stove head 1 and below the first air outlet 23. The second air outlet 24 is communicated with the lower air inlet of the exhaust fan 5. By using an F-shaped cross-section air duct for the main air duct 2, and the main air duct 2 includes a main air inlet 22, a first air outlet 23, and a second air outlet 24, and by starting the second air outlet 24, the duct body 21, and the first air outlet 23, the main air inlet 22 at the rear side of the integrated stove head 1 is always communicated with the air inlet of the exhaust fan 5. In addition, the three-way air duct 3 is driven by the rotation adjustment component 7 to rotate horizontally, so as to selectively adjust the air outlet of the four-way air duct 4 to be selectively communicated with the air outlets of the two L-shaped side air ducts 3 or the first air outlet 23 of the main air duct 2, that is, to change the intake negative pressure of the main air inlet 22 on the main air duct 2 of the integrated stove or to extract oil fume simultaneously from the two L-shaped side air ducts 3 and the main air duct 2, achieving the effects of variable-pressure oil fume extraction, changing the number of oil fume extraction ports, and the relative size of the air inlets, and further improving the oil fume extraction performance and practicality of the integrated stove.
