Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam cleaning range hood technology, specifically a steam cleaning range hood demonstration device. Background Technology
[0002] After prolonged use, a lot of grease will accumulate on the inside of the range hood's fan. High-temperature steam cleaning is necessary to effectively remove this grease and ensure the range hood's smoke extraction efficiency. A dedicated demonstration device is needed to showcase the steam cleaning process, allowing customers to intuitively understand how the range hood operates.
[0003] Existing range hood display devices lack a structure that visually demonstrates the steam entering the inside of the exhaust fan, compromising the display effect. Furthermore, the lack of a blocking structure allows steam to easily leak out from the air inlet, affecting the cleaning effect. Utility Model Content
[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a steam-cleaning range hood display device. Through the installation of a transparent fan cover and a transparent side cover, air from outside the range hood enters through the air inlet when the range hood is ventilating. This air mixes with the steam emitted from the steam nozzles and enters the drawer. From the steam inlet on the upper side of the drawer, it enters the spiral duct. The transparent side cover and fan cover allow for direct observation of the steam cleaning process within the spiral duct, ensuring a good display effect and effectively solving the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a steam-cleaning range hood display device, comprising a housing, a transparent fan cover plate on one side of the housing, a transparent side cover plate on one side of the transparent fan cover plate, a baffle plate on the bottom side of the inner cavity of the transparent side cover plate, an air inlet hole on one side of the housing of the baffle plate, a steam inlet hole on the lower side inside the transparent fan cover plate, two drawers on the bottom side of the housing, and two steam nozzles on the side of the housing adjacent to the baffle plate, with a connector connected to one side of each steam nozzle.
[0006] Furthermore, a spiral air duct is provided above the steam inlet, and a motor is provided at the center of the spiral air duct.
[0007] Furthermore, an air outlet is provided at the air outlet position of the spiral air duct, and a heat dissipation hole is provided on the upper side of the housing.
[0008] Furthermore, a power cord is installed on one side of the enclosure, and a control module is installed inside the enclosure below the heat dissipation holes.
[0009] Furthermore, the drawer is connected to the cabinet via a slide rail, and the transparent cover plate for the fan and the transparent side cover plate are bonded to the cabinet.
[0010] Furthermore, a centrifugal fan blade is connected to the output shaft of the motor, and the steam nozzle is connected to the connector via a thread.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the setting of a transparent fan cover and a transparent side cover, allows air from outside the range hood to enter through the air inlet when the range hood is ventilating. The air mixes with the steam sprayed from the steam nozzle and enters the drawer. It then enters the spiral duct from the steam inlet on the upper side of the other side of the drawer. The process of steam entering the spiral duct for steam cleaning can be directly observed through the transparent side cover and the transparent fan cover, thus ensuring the display effect of the display device.
[0013] 2. This utility model uses a baffle to block the air entering through the air inlet and prevents steam from leaking out of the air inlet from the steam nozzle, thus ensuring the amount of steam for steam cleaning and thus ensuring the cleaning effect. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3 This embodiment provides a technical solution: a steam-washing range hood display device, including a housing 1, a fan transparent cover 2 on one side of the housing 1, a transparent side cover 14 on one side of the fan transparent cover 2, a baffle 9 on the bottom side of the inner cavity of the transparent side cover 14, an air inlet 10 on one side of the housing 1 of the baffle 9, a steam inlet 8 on the lower side inside the fan transparent cover 2, two drawers 3 on the bottom side of the inner side of the housing 1, and two steam nozzles 11 on the side of the housing 1 adjacent to the baffle 9, with a connector 12 connected to one side of the steam nozzle 11.
[0020] like Figure 1-3 As shown, during the steam cleaning demonstration, the motor 7 drives the centrifugal fan blades to rotate, which in turn causes air to be discharged from the air outlet 15 through the spiral air duct 6. The air outside the housing 1 enters the housing through the air inlet 10 under the action of pressure difference, mixes with the steam sprayed from the steam nozzle 11, and then enters the drawer 3. It then enters the cavity with the spiral air duct 6 through the steam inlet 8 on one side of the drawer 3, and then enters the centrifugal fan blades, and further enters the inner side of the spiral air duct 6. The steam cleans the oil stains and finally discharges from the air outlet 15. The drawer 3 can collect the condensate of the steam.
[0021] A spiral air duct 6 is provided on the upper part of the steam inlet 8, and a motor 7 is provided in the center of the spiral air duct 6.
[0022] The spiral air duct 6 has an air outlet 15 at the air outlet position, and the upper side of the housing 1 has a heat dissipation hole 4.

[0024] Drawer 3 is connected to cabinet 1 via a slide rail, and the fan transparent cover 2 and transparent side cover 14 are bonded to cabinet 1.
[0025] Centrifugal fan blades are connected to the output shaft of motor 7, and steam nozzle 11 is connected to connector 12 by thread.
[0026] The working principle of the steam cleaning range hood display device provided by this utility model is as follows: Figures 1-3As shown, during the steam cleaning demonstration, the motor 7 drives the centrifugal fan blades to rotate, which in turn causes air to be discharged from the air outlet 15 through the spiral air duct 6. The air outside the housing 1 enters the housing through the air inlet 10 under the action of pressure difference, mixes with the steam sprayed from the steam nozzle 11, and then enters the drawer 3. It then enters the cavity with the spiral air duct 6 through the steam inlet 8 on one side of the drawer 3, and then enters the centrifugal fan blades, and further enters the inner side of the spiral air duct 6. The steam cleans the oil stains and finally discharges from the air outlet 15. The drawer 3 can collect the condensate of the steam.
