Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a range hood. Background Technology

[0002] Existing range hoods with cleaning functions are generally equipped with a water tank, which supplies water to the cleaning device, which then cleans the range hood.

[0003] For example, the Chinese invention patent with application number CN201710425099.3, entitled "Cleaning Control Method for Self-Cleaning Range Hood" (authorization announcement number CN108006740B), includes a cover, a fan, a smoke collection hood, a smoke guide plate, and an oil collection cup. The fan is located inside the cover. The range hood also includes a water tank and an electric heating element. The water tank is connected to a water inlet pipe that can enter into the volute. The electric heating element is located inside the aforementioned volute and near the bottom of the volute. The smoke guide plate can guide the cleaning water or cleaning liquid flowing out of the oil leakage port to the oil collection cup.

[0004] For example, the Chinese utility model patent with application number CN202323102706.2, entitled "A Range Hood" (authorization announcement number CN221403164U), includes the following components: a housing with an exhaust channel having an inlet and an outlet; a semiconductor cooling element with its cold end acting on the exhaust channel; a water tank with a heat-conducting wall adjacent to or in contact with the hot end of the semiconductor cooling element; and an atomizing device for atomizing water in the water tank to the inlet and / or outlet of the exhaust channel.

[0005] Most existing range hoods have water tanks that are either externally located on the top of the range hood or internally installed inside, which makes it inconvenient to add water to the tank. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a range hood that is easy to add water to the water tank, in light of the current state of the technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a range hood, comprising:

[0008] The fume hood has a hollow interior forming a fume collection chamber, and the fume hood is provided with an air inlet for the oil fume airflow to enter the fume collection chamber.

[0009] Water tank;

[0010] Its features are:

[0011] The side wall of the smoke collection hood is provided with a mounting groove that is recessed inward relative to the side wall and has an opening facing outward.

[0012] The water tank is constrained within the mounting groove by the slot and can be detached from the mounting groove.

[0013] In this utility model, the upper mounting groove can be formed in the following ways:

[0014] 1. A portion of the side wall of the smoke hood is recessed into the smoke hood to form an installation groove with the opening facing outward. In this case, the installation groove is integrally formed into the side wall of the smoke hood.

[0015] 2. The side wall of the smoke hood has an opening, and a housing forming an installation groove is embedded in the opening.

[0016] The water tank can be placed in the mounting slot through the opening. Alternatively, it can be secured to the mounting slot using a detachable structure such as clips.

[0017] By setting an installation groove with the opposite side wall recessed inward and the groove opening facing outward on the side wall of the smoke collection hood, the water tank can be installed into the installation groove through the groove opening or removed from the installation groove, thus facilitating the installation and disassembly of the water tank and the addition of water.

[0018] For ease of operation, preferably, the mounting groove is located on the front wall of the smoke collection hood, with the groove opening facing forward, on the side of the range hood facing the user. This allows the user to assemble and disassemble the water tank from the front of the range hood.

[0019] Preferably, the air inlet is located below the mounting groove, and the rear wall of the mounting groove is spaced apart from the rear wall of the fume hood to form a channel for the oil fume airflow to pass through. This design of the mounting groove does not affect the flow of oil fume airflow. Furthermore, because the groove wall of the mounting groove is at a lower temperature due to the water in the water tank, the oil fume airflow flowing upwards through the air inlet can condense and flow downwards upon encountering the groove wall.

[0020] Preferably, the air inlet is a strip-shaped opening extending in the left-right direction of the smoke hood, and the mounting groove corresponds to the center of the air inlet in the left-right direction.

[0021] Preferably, it also includes a flap, which is connected to the smoke collection hood and can be opened or closed relative to the smoke collection hood. When closed, the flap covers the water tank, and when opened, the water tank is exposed.

[0022] When the flap is closed, it covers the water tank, preventing it from being exposed and keeping it contained within the mounting slot to prevent accidental detachment. Once the flap is open, the water tank can be removed for refilling.

[0023] Preferably, the flap is located on the front side of the smoke hood, and can be flipped forward to open relative to the smoke hood and flipped backward to close relative to the smoke hood.

[0024] Furthermore, when the flap is closed, the lower edge of the flap is the upper edge of the air inlet.

[0025] Preferably, the internal space of the mounting groove and the smoke collection chamber are two independent spaces. This prevents the oil fume airflow in the smoke collection chamber from contaminating the water tank inside the mounting groove.

[0026] In the above-mentioned solutions, preferably, the following further includes:

[0027] A fan frame is located above the smoke hood, and a fan system is installed inside the fan frame;

[0028] The cleaning module used for cleaning the fan system has its water inlet connected to the water outlet of the water tank.

[0029] That is, the water tank of this utility model can supply water to the cleaning module.

[0030] Preferably, the mounting groove is provided with an adapter, which has a connected water inlet and a water outlet. The water inlet is connected to the water outlet of the water tank, and the water outlet is connected to the water source inlet of the cleaning module.

[0031] Compared with the prior art, the advantages of this utility model are: by setting an installation groove with the opposite side wall recessed inward and the groove opening facing outward on the side wall of the smoke collection hood, the water tank can be installed into the installation groove through the groove opening or removed from the installation groove, thereby facilitating the disassembly and assembly of the water tank and the addition of water.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1-6 As shown, this is a preferred embodiment of a range hood according to the present invention. The range hood includes a smoke collection hood 1, a water tank 2, a flap 3, a fan frame 4, an adapter 5, and a cleaning module.

[0040] The smoke hood 1 has a hollow interior forming a smoke collection chamber 10. With the side of the smoke hood 1 facing the user as the front side, the smoke hood 1 has a left-right extending front sidewall. The front sidewall has: a vertically arranged upper portion 111 and a lower portion 112 located below the upper portion 111. The lower portion 112 slopes backward relative to the upper portion 111 from bottom to top, forming an air inlet 11 between itself and the lower edge of the upper portion 111 to allow the oil fume airflow into the smoke collection chamber 10. Simultaneously, the smoke hood 1 has a smoke inlet 14 located above the upper portion 111 to allow the oil fume airflow into the smoke collection chamber 10. Both the air inlet 11 and the smoke inlet 14 are left-right extending strips.

[0041] Meanwhile, the upper part 111 of the front sidewall of the fume hood is provided with a mounting groove 12 that is recessed inward relative to the upper part 111 and faces forward. The structure forming the mounting groove 12 is as follows: the upper part 111 of the front sidewall of the fume hood has an opening, and a housing forming the mounting groove 12 is embedded in the opening. The housing is connected to the rear sidewall of the fume hood by screws. The rear sidewall of the mounting groove 12 and the rear sidewall of the fume hood 1 are spaced apart to form a channel 13 for the flow of oil fume. Figure 4 , 6 As shown, the flow velocity of the oil fume increases when it passes through channel 13. To avoid abnormal sounds such as whistling, the depth of channel 13 in the front-to-back direction is as large as possible while still meeting the design requirements of the mounting groove 12. For example, let the depth of channel 13 in the front-to-back direction be D2, and the depth of the portion of the smoke collection chamber 10 above channel 13 be D1, satisfying D2 / D1≥20%. Please refer to [link to documentation] for details. Figure 4 Furthermore, the mounting groove 12 corresponds to the center of the air inlet 11 in the left-right direction. Let the length of the mounting groove 12 in the left-right direction be L2, and the length of the air inlet 11 in the left-right direction be L1. The condition L2 / L1≤40% is met to ensure the fume extraction effect. Moreover, the internal space of the mounting groove 12 and the smoke collection chamber 10 are two independent spaces.

[0042] Water tank 2 is placed in mounting slot 12 through the slot opening and can be detached from mounting slot 12.

[0043] The aforementioned flap 3 extends laterally and is erected on the front side of the upper part 111 of the smoke hood to cover the mounting groove 12 and the water tank 2 inside the mounting groove 12 (i.e., the flap 3 is closed relative to the smoke hood). At this time, if Figure 5 , 6As shown, some of the fumes can flow upwards along the front side of the flap 3 into the smoke inlet 14. The lower edge of the flap 3 forms the upper edge of the air inlet 11, and the upper edge of the flap 3 forms the lower edge of the smoke inlet 14. And as... Figures 1-4 As shown, the flap 3 can be flipped forward around the left-right extending axis 30 to expose the mounting groove 12 and the water tank inside the mounting groove 12 (i.e., the flap 3 is open relative to the smoke hood), with the axis 30 adjacent to the lower edge of the flap 3. The flap 3 can be driven by a power mechanism.

[0044] The aforementioned fan frame 4 is located above the smoke hood 1, and the fan frame 4 contains a fan system 40 (an existing centrifugal fan). The cleaning module is existing technology, and its water inlet is connected to the water outlet 21 of the water tank 2 through a pipeline with a water pump. The water outlet faces the fan system 40 and is used to clean the fan system 40.

[0045] To ensure that the connecting pipeline between the water tank and the cleaning module does not interfere with the installation and removal of the water tank, an adapter 5 is provided in the mounting slot 12. The adapter 5 has a connected inlet 51 and an outlet 52. The inlet 51 faces forward and is connected to the outlet 21 of the water tank 2 by inserting it in front and behind. The outlet 52 is connected to the water inlet of the cleaning module through a pipeline with a water pump. Thus, when the water tank is placed in the mounting slot 12, the outlet 21 on the water tank can be inserted into the inlet 51 of the adapter 5; when the water tank is moved forward and removed from the mounting slot 12, the outlet 21 on the water tank can be removed from the inlet 51 of the adapter 5. This facilitates operation.

[0046] The wastewater from the cleaning module after cleaning the fan system 40 flows downward under its own gravity and is collected in the oil cup below the smoke collection chamber. In this embodiment, the top wall of the installation groove 12 is designed to be inclined to guide the wastewater and avoid the wastewater from accumulating on the top wall of the installation groove 12.

[0047] The range hood of this invention can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the fan system 40 and other components to perform corresponding operations, thereby realizing intelligent control of the range hood and improving the user experience.

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0049] The term "vertical" is also used in the specification and claims of this utility model, meaning basically along the up and down direction, and is not limited to just the vertical direction, but can also be slightly deviated from the vertical direction.
