Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. With the improvement of people's living standards, multi-level intelligent range hoods are relatively popular. For example, the invention patent application with application publication number CN202010923493.1 discloses a multi-connected range hood and its control method. The multi-connected range hood includes: an outdoor range hood main unit, multiple indoor terminal units, a main air duct, multiple branch air ducts, and a detection module. After obtaining the information that at least one indoor terminal unit in the kitchen is in working condition, the main control box can control the fan to start exhaust at a preset initial speed. The fumes in the kitchen are drawn into the indoor terminal unit and merged into the main air duct through the branch air duct, and then discharged into the atmosphere after being processed by the outdoor range hood main unit.

[0003] However, the above-mentioned multi-stage intelligent range hood still has certain shortcomings. Since the outdoor host of the multi-stage intelligent range hood is usually placed in an outdoor environment, electrical components such as an integrated circuit board and a terminal board are arranged in the outdoor electrical control box to achieve connection and control with the indoor unit, and also a power interface that can be electrically connected to an external power supply. When the outdoor host is working, the electrical components will generate heat. In particular, when the outdoor host runs for too long, the electrical components will accumulate more heat. If this heat cannot be dissipated in time, the host is prone to hidden dangers such as failure, and the life of the control board will be shortened, seriously affecting its performance.

[0004] Therefore, existing range hoods need further improvement. Utility Model Content

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0026] Figure 1-Figure 4 A preferred embodiment of the range hood of the utility model is shown. The range hood includes a range hood (not shown) and an outdoor host device, wherein the range hood is arranged indoors and generally includes a smoke collecting hood for smoke intake and smoke collection. The outdoor host device is generally arranged outdoors, and includes a fan housing 10, a fan system 12, an exhaust housing 20 and a control box 13. The fan system 12 is arranged in the fan housing 10 to provide negative pressure for extracting and exhausting the range hood.

[0027] The fan housing 10 is placed on a base 30, and its side can be fluidly connected to the indoor range fumes suction device through a pipeline. The exhaust housing 20 is connected to the top of the fan housing 10, and an air outlet 100 is provided on the top plate of the top of the fan housing 10, and the opening direction of the air outlet 100 is arranged upward. In order to guide the exhaust airflow of the fan system 12 upward, the air outlet 100 of the fan housing 10 is also connected to an air guide 11 extending upward from the outer peripheral edge of the air outlet 100. Specifically, the air guide 11 is located in the exhaust housing 20 as a whole, and its highest position (i.e., the upper port position) is located at the approximately middle position of the exhaust housing 20. A filter 110 is arranged at the outlet of the air guide 11, and the filter 110 can make the airflow of the air guide 11 more uniform. An exhaust port is provided on the top plate of the exhaust housing 20, and an air outlet grille 22 is provided at the exhaust port. The middle part of the air outlet grille 22 is a closed plate structure, and the bottom of the closed plate is connected to a first shielding plate 23 arranged obliquely relative to the horizontal plane through a suspension. The first shielding plate 23 is correspondingly shielded above the upper port of the air guide 11, thereby preventing rainwater from entering the fan system 12 through the air guide 11 and causing damage to the components in the fan system 12. The inclined first shielding plate 23 can also prevent rainwater dripping on the first shielding plate 23 from accumulating on the surface of the first shielding plate 23. The inner wall surface of the side wall of the exhaust box body 20 is also covered with a sound insulation member 24 to reduce the transmission of noise to the outside.

[0028] The control box 13 of this embodiment is located in the exhaust box 20. Specifically, the control box 13 includes a box body 131 and a control board 132 disposed in the box body 131, and the control board 132 is electrically connected to the control system of the range hood. The control box 13 is disposed adjacent to the side wall of the exhaust box 20 and deviates from the air outlet 100 of the fan box 10 in the horizontal direction, thereby preventing the direct blowing of the air from the fan system 12 from adversely affecting the control box 13. Of course, in order to improve the heat dissipation efficiency, heat dissipation fins 1310 are also distributed on the side wall of the control box 13 facing the exhaust box 20, which can effectively increase the heat dissipation area and improve the heat dissipation efficiency.

[0029] A second shielding plate 25 corresponding to the top of the control box 13 is also provided on the inner wall of the exhaust box body 20. The second shielding plate 25 extends toward the exhaust box body 20 and tilts downward, thereby preventing rainwater from falling from above from contacting the control box 13 and affecting the service life of the control box 13.

[0030] See also Figure 1 A door panel 21 for opening the exhaust box 20 from the outside is provided on the side wall of the exhaust box 20 in an area opposite to the control box 13, and a handle 210 is provided on the outer wall of the door panel 21 and is recessed toward the exhaust box 20. After opening the door panel 21, the control box 13 can be exposed, thereby facilitating later inspection and maintenance.

[0031] In this embodiment, the electric control box is placed at the air outlet 100 of the fan system 12 of the outdoor host device. When the outdoor host device is working, the fan system 12 blows out air, and the electric control box can be effectively cooled, thereby avoiding the problem of malfunction of the outdoor host device due to the failure to dissipate heat in time due to long-term operation, thereby extending the service life.
