Abstract

An instant material mixing and feeding hopper for powder flocculant or washing powder, and a washing machine. The instant material mixing and feeding hopper comprises a hopper upper cover (1) and a hopper body (2) that can be detachably connected. The hopper upper cover is provided with a chamber whose bottom is open. The chamber communicates with an inner chamber of the hopper body. A water intake pipe (4) is connected to the chamber of the hopper upper cover along a tangential direction of the hopper. A central axis of a water inlet formed by the water intake pipe and the hopper upper cover is parallel to a cross section of the hopper. A branch water intake pipe (6) communicating with the hopper body is disposed at the lower part of the hopper body. The detachable structure is easy to clean; the water intake pipe is connected to the hopper upper cover along the tangential direction of the hopper; when water passes through the water intake pipe and enters the chamber of the hopper upper cover, the water enters the chamber along the tangential direction of a hopper wall, so that the water flow shows a whirlpool state when the water flows along the hopper wall in the hopper, thereby bringing a very good stirring and dissolution effect on powder flocculant or washing powder fed from the top of the hopper. The branch water intake pipe disposed at the lower part of the hopper body can prevent water centering the hopper from overflowing when the quantity of water greatly fluctuates.

Embodiment 1

As shown in conjunction with Figures 1, 2, and 3, the instant mixing funnel of the powder flocculant or washing powder of the present invention comprises a detachably connected funnel upper cover 1 and a funnel body 2 in two parts. The funnel upper cover 1 and the funnel body 2 are respectively provided with interfitting fastening claws 10 and tabs, and the funnel upper cover 1 and the funnel body 2 are fixedly connected by the fastening of the fastening claws 10 and the tabs.

The funnel upper cover 1 has a cavity open at the bottom, the cavity is an arched cavity 8, and the arched cavity 8 communicates with the inner cavity of the funnel body 2. In the present embodiment, the funnel upper cover 1 is annular, and the central hole is provided for the powder dispensing device to dispense powder flocculant or washing powder into the funnel. The annular side of the upper cover 1 has an inner flange and an outer flange which are connected at the top, and an arched cavity 8 which is open at the bottom between the inner flange and the outer flange, and the bottom of the funnel upper cover and the wall of the funnel body 2 Sealed connection. In order to achieve a sealing connection between the bottom of the funnel upper cover and the wall of the funnel body 2, an annular groove is formed at the top end of the funnel body 2 as a sealing groove 11, and an annular rib is provided at the bottom end of the outer flange of the funnel upper cover 1 The annular groove is fitted, and the annular rib is inserted into the annular groove to insert and seal the two. In order to further enhance the sealing effect, a sealing ring 3 is provided in the annular groove, and the annular rib pressing sealing ring 3 makes the sealing engagement of the annular rib and the sealing groove 11 better.

The inlet pipe 4 is connected to the arched cavity 8 of the funnel upper cover 1 in the tangential direction of the funnel, and the central axis of the water inlet formed by the inlet pipe 4 and the funnel upper cover 1 is parallel to the cross section of the funnel; and the lower part of the funnel body 2 is also provided A split inlet pipe 6 communicating with the funnel body 2.

The inner flange of the funnel upper cover 1 has a radial gap with the inner wall of the funnel body so that water entering the arcuate cavity 8 of the funnel upper cover 1 from the inlet pipe 4 can flow into the inner cavity of the funnel body 2. The inner flange of the funnel upper cover 1 prevents water splashing from the water inlet into the arcuate cavity 8 of the funnel upper cover 1 at high speed to wet the dispensing opening of the powder delivery device above the funnel.

The water enters the arcuate cavity 8 of the funnel upper cover 1 from the inlet pipe 4 in the tangential direction of the funnel, rotates along the funnel wall to form a vortex and flows downward under the force of gravity, and the vortex water flow can be discharged from above the funnel into the vortex The powder flocculant or washing powder is better released.

The arched cavity 8 provides more volume, reduces the water flow rate, and acts as a reservoir to increase the amount of water on the funnel wall to prevent the feed from being dissolved or not dissolved on the funnel wall.

In order to block the splash of water entering the arched cavity, the bottom end of the inner flange extends downwardly at least to the inlet pipe and The center axis of the water inlet formed by the upper cover of the funnel is flush. In this embodiment, the bottom end of the inner flange extends downward beyond the bottom end of the water inlet formed by the inlet pipe and the upper cover of the funnel so that the bead covers the entire water inlet.

The inner flange of the upper cover 1 of the funnel is parallel to the inner wall of the corresponding funnel body 2 so as not to impede the rotation of the water flow.

The instant mixing funnel of the powder flocculant or the washing powder further comprises a water flow accelerator 5 which is tubular and whose inner cavity gradually becomes smaller in the direction of the water flow, that is, the necking structure. In the present embodiment, the water flow accelerator 5 is fixedly disposed in the inlet pipe 4 at a position close to the water inlet, and the outer wall thereof closely fits the inner wall of the inlet pipe 4. The water flow accelerator 5 can make the water entering the arcuate cavity 8 of the funnel upper cover 1 from the inlet pipe 4 more rapid, and the vortex formed is more powerful, thereby facilitating the dissolution of the powder flocculant or the washing powder.

In other embodiments, the large diameter end of the inner cavity of the water flow accelerator 5 is connected to the inlet pipe 4, and the small diameter end of the inner cavity is connected to the funnel upper cover 1. That is, the water flow accelerator 5 is connected as a separate component to the inlet pipe 4 and the funnel upper cover 1.

The funnel body 2 is divided into a plurality of sections connected from top to bottom. The slope of the wall of the upper section of the funnel body 2 is smaller than the slope of the wall of the lower section, and the wall of the upper section of the funnel body 2 tends to be gentler than the lower section of the funnel body 2. The wall of the lower section of the funnel body 2 is more upright. At the lower end of the funnel body 2, a split inlet pipe 6 communicating with the funnel body 2 is disposed, and a water outlet 12 is provided at the bottom end of the funnel body.

The split inlet pipe 6 and the inlet pipe 4 are connected to the water source through the tee 7, and the purpose of providing the split inlet pipe 6 is to prevent the water from overflowing only from the inlet pipe 4 into the funnel when the amount of water fluctuates greatly.

The invention relates to a powder mixing flocculating agent or a washing powder instant mixing feeding funnel, the structure of the detachable connecting funnel upper cover and the funnel body is easy to clean, and the inlet water pipe is connected with the funnel upper cover along the funnel tangential direction, the inlet water pipe and the funnel upper cover The central axis of the formed water inlet is parallel to the cross section of the funnel, and the water enters along the tangential direction of the funnel wall through the inlet pipe into the arched cavity of the upper cover of the funnel, so that the water flow flows in the funnel along the funnel wall in a swirling state, and the water flow accelerator can The water is accelerated from the inlet pipe into the funnel, so that the powder flocculant or washing powder placed from the top of the funnel has a good instant stirring and release effect. The split inlet pipe provided at the lower part of the funnel body can prevent the water entering the funnel from overflowing when the water volume fluctuates greatly, soaking the inlet of the powder delivery device located above the funnel.
