Description

Technical Field

[0001] The utility model belongs to the technical field of range hoods, and in particular relates to a range hood with double independent air covers. Background Art

[0002] Range hoods are very common kitchen appliances in daily life. By starting the range hood, the fumes generated during cooking can be first sucked into the range hood and then further transferred to the outside atmosphere. However, the multiple air intakes of the range hoods currently on the market all take in air together. When only one side of the stove is working, it is not possible to effectively determine which side of the stove below is producing fumes. Therefore, the fan device needs to be turned on at a larger gear to ensure the smoke extraction effect. The existing range hoods cannot maximize the performance of the fan device and have high energy consumption. Utility Model Content

[0003] The purpose of the present invention is to overcome the problems of existing range hoods that the existing range hoods cannot maximize the performance of the fan device and have high energy consumption, and to provide a range hood with double independent air covers, in which independent air covers are respectively arranged at the first air suction port and the second air suction port so as to selectively open the air suction port to reduce the energy consumption of the range hood.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A range hood with two independent air covers comprises a range hood body, an air cover assembly, and a control module; the range hood body is provided with a first air suction port, a second air suction port, and a fan device located inside; the air cover assembly comprises a first air cover and a second air cover, the first air cover is connected to the range hood body and is driven by a first driver to relatively open or close the first air suction port, and the second air cover is connected to the range hood body and is driven by a second driver to relatively open or close the second air suction port; the control module is electrically connected to the first driver, the second driver, the fan device, and the driving mechanism, respectively; when the fan device is working, the range hood has a first working state in which only the first air suction port is opened, a second working state in which only the second air suction port is opened, and a third working state in which both the first air suction port and the second air suction port are opened.

[0006] Compared with the prior art, the range hood with double independent air covers of the utility model configures a first air cover at the first air suction port of the range hood body and a second air cover at the second air suction port, so that the range hood can selectively open the first air suction port or the second air suction port and close the other air suction port according to the position where the stove generates oil smoke, so that the fan device can perform oil smoke suction work at a lower power and ensure the suction effect. Alternatively, when oil smoke is generated at both sides of the stove at the same time, the first air suction port and the second air suction port are opened at the same time, so that the oil smoke suction work can be performed on both sides of the stove at the same time, effectively solving the problem of oil smoke escape, ensuring the maximum use of the performance of the fan device, and the oil fume suction effect is good.

[0007] Furthermore, it also includes a sensing device electrically connected to the control module, the sensing device is used to detect whether the temperature or oil fume concentration at the two sides below the range hood reaches a preset value, and the control module controls the range hood body to enter the first working state, the second working state or the third working state according to the feedback signal of the sensing device; through such a setting, the working state of the range hood can be intelligently controlled by setting the sensing device.

[0008] Furthermore, the sensing device is an infrared thermal imager or a temperature sensor or a group of oil fume concentration detectors. When the sensing device detects that a preset temperature value or a preset oil fume concentration value is reached at one side of the bottom of the range hood, the sensing device feeds back a signal to a control module to cause the range hood to enter a first state or a second state accordingly; or, when the preset temperature value or the preset oil fume concentration value is reached at both sides at the same time, the sensing device feeds back a signal to the control module to cause the range hood to enter a third state. Through such a configuration, the sensing device detects the working state of the stove by detecting the temperature or the oil fume concentration, and the detection method has good reliability.

[0009] Furthermore, the fan device is a double-inlet centrifugal fan, and an exhaust pipe is connected to the top of the fan device. Through such an arrangement, when the range hood is in the third working state, the double-inlet centrifugal fan can simultaneously absorb oil fume from the first air intake or the second air intake on both sides, respectively, and the oil fume removal effect is good.

[0010] Furthermore, the relative outer sides of the first air cover and the second air cover are respectively rotatably connected to the range hood body, and the outer sides of the first air cover and the second air cover are respectively transmission connected to the corresponding drivers through a connecting rod structure, and the connecting rod structure includes a rocker rod and a push rod that are rotatably connected to each other at one end, and the first driver and the second driver are motors respectively, one end of the rocker rod of one group is transmission connected to the first driver, and the other end of the push rod is transmission connected to the first air cover, and one end of the rocker rod of the other group is transmission connected to the second driver, and the other end of the push rod is transmission connected to the second air cover; through such an arrangement, the connecting rod structure is simply arranged, and the effect of driving the first air cover and the second air cover to open or close is good.

[0011] Furthermore, it also includes a WiFi module connected to the control module, and the mobile terminal can control the working state of the range hood through the WiFi module; through such a setting, it is convenient for the user to use the mobile terminal to control the working state of the range hood through the Internet, which is convenient to use.

[0013] Furthermore, the control module can adaptively adjust the air volume of the fan device according to the detected temperature or oil fume concentration; through such a setting, the problem of oil fume escape is effectively solved, the performance of the fan device is maximized, and the oil fume absorption effect is good.

[0014] Furthermore, the first air suction port and the second air suction port are openings that are interconnected, or the first air suction port and the second air suction port are divided into two independent openings. BRIEF DESCRIPTION OF THE DRAWINGS
