Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, in particular to an annular water baffle and a range hood. Background Art

[0002] When assembling a range hood with a cleaning function, you need to first stick a circle of sponge on the air inlet of the fan casing. The ring-shaped sponge is mainly used to block water to prevent water from splashing out of the fan through the air inlet when cleaning the wind wheel. After the sponge is bonded, the fan and the chassis of the range hood are fixed and installed.

[0003] The sponge for the air inlet needs to be manually cleaned first, then glued with a handheld glue gun, and finally the ring sponge is glued to the glued area, and finally it needs to be fully solidified, which is inefficient and difficult to control the quality. In addition, after long-term use, the sponge strip is affected by oil seepage, and some of the bonding fails, resulting in a gap between the sponge strip and the fan housing, resulting in the failure of the water-blocking function.

When the first arc plate 12 is installed in place, the first arc plate 12 and the second arc plate 13 are butt-jointed and together form a circular ring shape.

[0033] like Figure 1-4 As shown, in a preferred embodiment of the utility model, the first curved plate 12 and the second curved plate 13 are both elastic. For example, the first curved plate 12 and the second curved plate 13 are made of deformable materials such as rubber, soft plastic, and thin steel sheets, so that the first curved plate 12 and the second curved plate 13 can be easily installed on the fan 2.

[0034] like Figure 1-4 As shown, in a preferred embodiment of the utility model, a first clamping portion 121 is provided at both ends of the first arc plate 12, and a second clamping portion 131 is provided on the second arc plate 13 corresponding to the first clamping portion 121, and the second clamping portion 131 is clamped with the first clamping portion 121 to improve the overall structural strength after connection.

The slot 111 is formed by the arc wall 1121, the arc sheet 1122 and the annular water baffle 1. Preferably, the arc wall 1121, the arc sheet 1122 and the annular water baffle 1 are integrally formed.

[0040] like Figure 2-3 As shown, in a preferred embodiment of the present utility model, the annular protrusion 11 is close to the outer edge of the annular water baffle 1 .

[0041] like Figure 2 and Figure 3 As shown, the annular water baffle plate 1 is a plane from the annular protrusion 11 to the outer edge, and is an inner concave and outer convex structure from the annular protrusion 11 to the inner edge, so that when cleaning the fan 2, the inner concave surface of the annular water baffle plate 1 blocks water to prevent water from splashing out of the fan 2.

[0042] exist Figure 3 In the figure, arrow A indicates the direction of water removal during cleaning.

[0043] In addition, since the outer surface of the annular water baffle 1 is a curved surface, the stability and smoothness of the airflow during air intake are improved, and turbulence is prevented.

[0044] like Figure 1-4 As shown, in a preferred embodiment of the utility model, it also includes a plurality of screws, the first arc plate 12 and the second arc plate 13 are both spaced apart with first through holes 122 equal to the number of the screws, the fan 2 is provided with second through holes corresponding to the first through holes 122, and the first arc plate 12 and the second arc plate 13 are both connected to the fan 2 by screws to improve the connection strength.

[0046] The range hood body comprises a fan 2, a cleaning pump and a nozzle 3. The fan 2 comprises a fan housing 21, a motor 22 arranged in the fan housing 21, a wind wheel 23 installed on the rotating shaft of the motor 22 and the above-mentioned annular water baffle.

[0047] The nozzle 3 is installed on the fan housing 21, and the nozzle 3 faces the wind wheel 23, and the nozzle 3 is connected with the water outlet of the cleaning pump.

[0048] The annular water baffle plate 1 is clamped at the air inlet of the fan housing 21 through the clamping groove 111 , and the inner diameter of the annular water baffle plate 1 is smaller than the inner diameter of the wind wheel 23 .

[0049] When the range hood is being cleaned, the annular water baffle 1 at the air inlet can block the water thrown over by the rotation of the impeller, preventing the water from flowing out of the air inlet.

[0050] The range hood provided by the embodiment of the utility model achieves the effects of high assembly efficiency, stable performance and long service life due to the adoption of the above-mentioned annular water baffle plate.

[0051] like Figure 3 As shown, in a preferred embodiment of the utility model, an inner turn-down edge is provided at the air inlet of the fan 2, and the card slot 111 is carded on the inner turn-down edge to further enhance the splash-proof effect.
