[0035] A top-suction range hood is usually installed above a stove, and can draw the fumes in the kitchen upward and discharge them into the external environment. Its suction area affects its ability to draw fumes. An existing top-suction range hood includes a base 100 and an exhaust assembly 800. The base 100 has a smoke collection channel, and a suction hole is opened at the lower end of the smoke collection channel. The exhaust assembly 800 is arranged on the base 100 and is used to draw the smoke collection channel. In order to improve the suction capacity of the top-suction range hood, there is an existing solution of enlarging the suction hole. Although this solution increases the suction area, the horizontal size of the lower end of the base 100 is also increased, and the space occupied is relatively large, which is not conducive to the storage and transportation of the range hood.

[0036] Reference Figures 1 to 5 , which is a space-saving range hood according to an embodiment of the utility model, comprises a base 100 and a smoke collecting hood 200. The base 100 is provided with a main smoke collecting channel 110, and a first suction hole with a hole axis in the vertical direction is provided at the lower end of the main smoke collecting channel 110; the smoke collecting hood 200 is movably arranged on the base 100 in the horizontal direction; the smoke collecting hood 200 is provided with a secondary smoke collecting channel 210, and a second suction hole with a hole axis in the vertical direction is provided at the lower end of the secondary smoke collecting channel 210, and the secondary smoke collecting channel 210 is connected with the main smoke collecting channel 110; the smoke collecting hood 200 has an unfolding position and a storage position. In the unfolding position, the smoke collecting hood 200 extends horizontally relative to the base 100, and the first suction hole and the second suction hole are arranged side by side in the horizontal direction; in the storage position, the smoke collecting hood 200 is retracted relative to the base 100, the first suction hole and the second suction hole are opposite to each other in the vertical direction, and the secondary smoke collecting channel 210 is accommodated in the main smoke collecting channel 110.

[0037] An exhaust assembly 800 is provided at the base 100, and the exhaust assembly 800 is used to draw air from the main smoke collecting channel 110. When the range hood is in use, the smoke hood 200 can be horizontally extended to the unfolded position. At this time, the first suction hole and the second suction hole are horizontally arranged side by side, and the smoke generated in the cooking area is sucked from bottom to top, thereby having a better suction capacity; when the range hood is not in use, the smoke hood 200 can be retracted to the storage position, reducing the size of the smoke hood 200 extending relative to the base 100, thereby reducing the space occupied and facilitating the storage and transportation of the range hood.

[0038] In the embodiment, a first filter screen 310 and a second filter screen 320 are further included. The first filter screen 310 is horizontally arranged on the base body 100 and covers the first suction hole, and the second filter screen 320 is horizontally arranged on the smoke hood 200 and covers the second suction hole. The first filter screen 310 and the second filter screen 320 are arranged to facilitate filtering the oil mist in the oil smoke.

[0039] Specifically, the first filter 310 is a metal filter, and the second filter 320 is a metal filter. The metal filter can condense the oil smoke in the airflow to form fine oil droplets and water droplets that adhere to the metal filter. It is understandable that the first filter 310 and the second filter 320 can also be other types of filters, and those skilled in the art can configure them specifically according to actual needs.

[0040] In the embodiment, a reversing valve structure 400 is further included. The seat body 100 is provided with an outer exhaust channel 120 and an inner exhaust channel 130. The main smoke collecting channel 110 is communicated with the outer exhaust channel 120 and the inner exhaust channel 130 respectively. The reversing valve structure 400 is provided on the seat body 100. The reversing valve structure 400 is used to open one of the outer exhaust channel 120 and the inner exhaust channel 130 and close the other of the outer exhaust channel 120 and the inner exhaust channel 130. When the exhaust assembly 800 of the range hood is started, if the reversing valve structure 400 is in the state of opening the outer exhaust channel 120 and closing the inner exhaust channel 130, the range hood can normally absorb the oil smoke generated in the cooking area, and the oil smoke passes through the main smoke collecting channel 110 and the outer exhaust channel 120 and is then discharged to the outside; if the reversing valve structure 400 is in the state of opening the inner exhaust channel 130 and closing the outer exhaust channel 120, the range hood can enhance the indoor air circulation and improve the indoor air flow, and the range hood is suitable for use during non-cooking time. The above structure enables the range hood to be used both when cooking and when not cooking, and has a wide range of applications.

[0041] In the embodiment, the reversing valve structure 400 includes a first flap, one end of the outer exhaust channel 120, one end of the inner exhaust channel 130 and one end of the main smoke collecting channel 110 are connected, the first flap is rotatably arranged on the seat body 100 and is located at the joint of the outer exhaust channel 120 and the inner exhaust channel 130, and the first flap can be rotated to close one end of the outer exhaust channel 120 or rotated to close one end of the inner exhaust channel 130. One end of the outer exhaust channel 120, one end of the inner exhaust channel 130 and one end of the main smoke collecting channel 110 are connected, when the first flap closes the outer exhaust channel 120, the airflow in the main smoke collecting channel 110 can only be discharged from the range hood through the inner exhaust channel 130, forming an indoor air circulation; when the first flap closes the inner exhaust channel 130, the airflow in the main smoke collecting channel 110 can only be discharged from the range hood through the outer exhaust channel 120, forming an air external circulation. The above-mentioned reversing valve structure 400 has a simple structure and is easy to implement.

[0042] Specifically, the first flap is provided with a rotating shaft, the base body 100 is provided with a rotating shaft hole, and the rotating shaft is passed through the rotating shaft hole, so that the first flap can rotate relative to the base body 100. It is conceivable that the first flap rotation setting can also be realized by other structures, for example, the first flap is connected to the base body 100 by a hinge, so that the first flap can rotate relative to the base body 100.

[0043] It is conceivable that the reversing valve structure 400 can also be other structures. For example, the reversing valve structure 400 includes two solenoid valves, one of which is arranged in the external exhaust channel 120 and is used to control the on-off of the external exhaust channel 120, and the other solenoid valve is arranged in the internal exhaust channel 130 and is used to control the on-off of the internal exhaust channel 130. When one of the two solenoid valves is opened, the other is closed, thereby realizing the function of the above-mentioned reversing valve structure 400.

[0044] In the embodiment, the inner exhaust passage 130 is provided with an inner exhaust port 140, and the inner exhaust port 140 is located on one side of the base body 100 along the horizontal direction. The fume hood 200 is in the storage position, and the fume hood 200 blocks the inner exhaust port 140; the fume hood 200 is in the deployed position, and the inner exhaust port 140 is exposed to the base body 100. In the above structure, when the range hood is not in use, the fume hood 200 is in the storage position, and the fume hood 200 blocks the inner exhaust port 140, which can reduce the risk of foreign matter entering the inner exhaust port 140 and improve the appearance comfort of the range hood. When the range hood is in use, the fume hood 200 is in the deployed position, and the inner exhaust port 140 can perform internal circulation normally.

[0045] In the embodiment, a one-way valve 500 is further included, and the one-way valve 500 is disposed in the external exhaust passage 120. The one-way valve 500 is disposed to reduce the risk of foreign matter entering the range hood due to the reverse flow of external air, and also reduce the risk of the first flap accidentally rotating due to the reverse flow of air.

[0046] In the embodiment, the one-way valve 500 includes a second flap, the external exhaust channel 120 is provided with an external exhaust hole, the hole axis of the external exhaust hole is arranged in the vertical direction, and one end of the second flap is pivotally connected to the seat body 100 and can be rotated to cover the external exhaust hole or rotated upward to open the exhaust hole. When the external exhaust channel 120 is not exhausted to the outside, the second flap automatically covers the external exhaust hole under the action of its own weight, and the backflow of external air can be blocked at this time; when the external exhaust channel 120 is exhausted to the outside, the airflow pushes up the other end of the second flap, so that the airflow can be discharged naturally.

[0047] Specifically, the one-way valve 500 is provided with two second flaps, the outer exhaust hole is a circular hole, each flap covers half of the outer exhaust hole, and the second flap can be arranged inside the outer exhaust hole. It is conceivable that when the one-way valve 500 is a second flap, the second flap can be arranged at the upper end of the outer exhaust hole.

[0048] It is conceivable that the one-way valve 500 may also be a valve with a check function such as a duckbill valve.

[0049] The micro switch 600 is also included. When the smoke hood 200 is in the storage position, the smoke hood 200 abuts against the micro switch 600; when the smoke hood 200 is in the unfolded position, the smoke hood 200 is separated from the micro switch 600. The micro switch 600 is provided to facilitate detection of the position of the smoke hood 200 relative to the base 100, providing a physical basis for automatically controlling the operation of the range hood.

[0050] Specifically, when the smoke hood 200 is in the storage position, the micro switch 600 is pressed and the range hood cannot be started, so as to prevent the two first filters 310 from overlapping and affecting the air flow and protecting the exhaust assembly 800; when the smoke hood 200 is in the unfolded position, the micro switch 600 is released and the range hood can be started.

[0051] In an embodiment, the smoke hood 200 is slidably disposed on the base body 100 along the front-to-back direction. The deployment position and the storage position are switched by sliding forward and backward, and the structure is simple and easy to implement. Specifically, a slide rail is disposed on the base body 100 along the front-to-back direction, and a slide bar is disposed on the smoke hood 200 along the front-to-back direction, and the slide bar is slidably connected to the slide rail, so that the smoke hood 200 can slide in the front-to-back direction relative to the base body 100. It is conceivable that the above functions can also be achieved in other ways, for example, a guide sleeve is disposed on the base body 100, and a guide column is disposed on the smoke hood 200 along the front-to-back direction, and the guide column is slidably penetrated in the guide sleeve, so that the smoke hood 200 can slide in the front-to-back direction relative to the base body 100.

[0052] It is conceivable that the smoke hood 200 can also switch between the deployed position and the stored position relative to the base 100 by rotating. For example, one end of the smoke hood 200 is pivotally connected to the base 100, and the smoke hood 200 is rotated to be retracted into or extended from the base 100.

[0053] Reference Figure 2 , and further includes an electric control box 700, which is arranged on the base body 100 and located in the main smoke collecting channel 110. The electric control box 700 is located in the main smoke collecting channel 110. When the range hood is in use, airflow will continue to be generated in the main smoke collecting channel 110. At this time, the airflow can dissipate the heat of the electric control components in the electric control box 700, so that the electric control components in the electric control box 700 maintain a suitable temperature, and avoid overheating and damage to the electric control components.

[0054] Specifically, the exhaust assembly 800 is disposed at the upper end of the main smoke collecting channel 110. The exhaust assembly 800 uses a centrifugal fan. It is understandable that the exhaust assembly 800 may also use an axial flow fan.

[0055] Specifically, two exhaust assemblies 800 and two first flaps are provided to improve the suction capacity of the range hood.
