Description

Water injection structure of clothing processing equipment and clothing processing equipment

Technical Field

The present invention relates to the technical field of clothing processing equipment, and in particular to a water injection structure of clothing processing equipment and the clothing processing equipment.

Background technique

Ordinary clothing processing equipment processes clothing by water washing or dry cleaning. This processing method can cause clothing to deform, feel worse, and become older with each washing.

To this end, manufacturers have introduced a steam washing method for clothing, which uses steam to wash clothes. The whole process is time-saving, energy-saving, refreshing, deodorizing, and wrinkle-removing, without damaging clothes.

The working process of the clothing treatment equipment in the steam washing mode is to inject water into the outer drum through the water inlet valve. When the water level reaches the preset water level, the water supply is stopped, and the heating tube is turned on to heat to generate sufficient steam. At the same time, the inner drum rotates at a low speed, and the clothes tumble in the inner drum filled with steam. The odor can be dissolved in the steam, and the steam moistens the clothes at the same time. After the odor is eliminated and moistened, the drying system blows hot air into the inner drum to dry the clothes, so as to remove wrinkles on the clothes.

In the existing clothes processing equipment, when water is poured into the outer drum, water will drip and splash into the inner drum, which does not meet the special requirement of steam washing without water immersion in the inner drum, hinders the steam washing and affects the effect of steam washing.

Summary of the invention

An object of the present invention is to provide a water injection structure of a clothes processing device and the clothes processing device, which can effectively prevent the injected water from flowing into the inner drum during steam washing.

To achieve this object, the present invention adopts the following technical solutions:

Embodiment 1

As shown in Fig. 1, this embodiment provides a water injection structure of a clothes processing device, comprising an inner drum 1, an outer drum 2 and a water retaining structure 3. The outer drum 2 is sleeved on the outer side of the inner drum 1, a water inlet 20 is provided on the outer drum 2, and the water retaining structure 3 is provided between the inner drum 1 and the outer drum 2. When injecting water, the water injected into the outer drum 2 from the water inlet 20 is blocked by the water retaining structure 3 and flows along the inner wall of the outer drum 2 to the bottom of the outer drum 2.

In the present invention, a water retaining structure 3 is provided at the water inlet 20, so that during the water injection operation, the water flow will be blocked by the water retaining structure 3, and then flow along the inner wall of the outer cylinder 2 to the bottom of the outer cylinder 2, so that during steam washing, the injected water entering the outer cylinder 2 from the water inlet 20 is reliably blocked and guided, effectively avoiding the injected water from flowing into the inner cylinder 1 during the water injection process, thereby ensuring the requirement that the inner cylinder 1 is not immersed in water during steam washing.

Specifically, the inner tube 1 includes an inner tube body 11 and an inner flange 12 arranged at the open end of the inner tube body 11, a water permeable hole 10 is arranged on the side wall of the inner tube body 11, and an inner clothes opening 13 is arranged on the inner flange 12. The outer tube 2 is sleeved on the outer side of the inner tube 1, and includes an outer tube body 21 and an outer flange 22 arranged at the open end of the outer tube body 21, and an outer clothes opening 23 is arranged on the outer flange 22 opposite to the inner clothes opening 13.

More specifically, the outer flange 22 is divided into an upper area 100 located above the outer garment opening 23 and a U-shaped area 200 surrounding the sides and bottom of the outer garment opening 23 .

In this embodiment, a gradually inwardly tapered structure 111 is provided at one end of the inner cylinder 11 connected to the inner flange 12, and no water-permeable holes 10 are distributed on the tapered structure 111, so that water droplets splashed at the front end of the side wall of the inner cylinder 11 can flow forward and downward to avoid the accumulation of water droplets.

Specifically, a bending structure 121 is provided on the inner flange 12 around the inner garment opening 13 , and the bending structure 121 can prevent water drops on the inner flange 12 from flowing toward the inner garment opening 13 .

Embodiment 2

As shown in Figures 2 and 3, this embodiment provides a water injection structure of a clothing processing device, and this embodiment further illustrates the connection relationship and specific structure of the water retaining structure on the basis of Example 1. In this embodiment, the water retaining structure 3 is specifically connected to the inner side of the outer drum 2, so that when the clothing is processed, the water retaining structure 3 does not rotate with the inner drum 1, and the water retaining function is safer and more reliable.

In this embodiment, the water inlet 20 is located at the upper half of the side wall of the outer cylinder 21, and the water retaining structure 3 extends downward from the water inlet 20 between the inner cylinder 1 and the outer cylinder 2. When water is injected, the water injected into the outer cylinder 2 from the water inlet 20 is blocked and directed to the lower half of the outer cylinder 2 by the water retaining structure 3, and flows along the inner wall of the outer cylinder 2 to the bottom of the outer cylinder 2. With the above arrangement, the water retaining structure 3 has the function of guiding flow on the basis of blocking, so that the injected water is prevented from being blocked by the water retaining structure 3, and then dripping from the upper half of the side wall of the outer cylinder 21 to the inner cylinder 11, and then entering the inner cylinder 1 from the water permeable hole 10 on the inner cylinder 11.

Optionally, when the water inlet 20 is located at the highest point of the outer tube 2, the water retaining structure 3 extends from the water inlet 20 to both sides, so that the injected water can flow to both sides along the water retaining structure 3, thereby improving the flow diversion rate.

Embodiment 3

As shown in FIG4 , this embodiment provides a water injection structure of a clothes processing device, which is different from the second embodiment in that, in this embodiment, the water inlet 20 is located at the lower half of the side wall of the outer cylinder 21 or the bottom wall of the cylinder, and the water retaining structure 3 is a retaining plate, covering the water inlet 20. When injecting water, the water injected into the outer cylinder 2 from the water inlet 20 is blocked by the water retaining structure 3 and then flows back to the bottom of the outer cylinder 2 under the action of gravity. At this time, the water retaining structure 3 has a simple shape and only needs to prevent the water injected from the water inlet 20 from impacting the inner cylinder 1.

Specifically, when the water inlet 20 is located at the lower half of the side wall of the outer cylinder body 21, the injected water is blocked by the water retaining structure 3, and then flows back to the inner wall of the outer cylinder 2, and flows to the bottom of the outer cylinder 2 along the inner wall of the outer cylinder 2; when the water inlet 20 is located at the bottom wall of the outer cylinder body 21, the injected water is blocked by the water retaining structure 3, and then splashes onto the bottom wall of the cylinder, and flows to the bottom of the outer cylinder 2 along the bottom wall of the cylinder under the influence of gravity, or directly falls to the bottom of the outer cylinder 2 under gravity.

Embodiment 4

As shown in FIG5 , this embodiment provides a water injection structure of a clothing treatment device, which is different from the second embodiment in that, in this embodiment, the water inlet 20 is located in the upper area 100, and the water retaining structure 3 extends from the water inlet 20 to the inside of the U-shaped area 200 between the inner tub 1 and the outer tub 2. When injecting water, the water injected into the outer tub 2 from the water inlet 20 is blocked and directed to the inside of the U-shaped area 200 by the water retaining structure 3, and flows to the bottom of the outer tub 2 along the inner flange 12 and the inner wall of the outer tub 2, or flows to the bottom of the outer tub 2 along the inner wall of the outer tub 2. At this time, the water retaining structure 3, after blocking the water, guides the injected water to the inside of the U-shaped area 200, preventing the water from flowing into the inner tub 1 through the inner clothing opening 13.

Specifically, when the water retaining structure 3 extends to the upper half of the inner tube 1, the injected water flows along the inner flange 12 and the inner wall of the outer tube 2 to the bottom of the outer tube 2 in sequence; when the water retaining structure 3 extends to the lower half of the inner tube 1, the injected water flows directly to the inner wall of the outer tube 2 under the action of gravity, and then flows along the inner wall of the outer tube 2 to the bottom of the outer tube 2.

More specifically, when the water retaining structure 3 extends to the upper half of the inner tube 1, the injected water needs to be diverted through the inner flange 12. At this time, it is set that during the steam washing process, the area on the inner flange 12 that first diverts the water flow first drops and then rises, so that the water attached to the inner flange 12 is scattered downward under the action of centrifugal force, thereby improving the safety of water injection.

Optionally, when the opening position of the water inlet 20 is higher than the highest point of the outer garment opening 23, the water retaining structure 3 extends from the water inlet 20 to both sides, so that the injected water can flow to both sides along the water retaining structure 3, thereby improving the diversion rate.

Embodiment 5

As shown in FIG6 , this embodiment provides a water injection structure of a clothes processing device, which is different from the second embodiment in that, in this embodiment, the water inlet 20 is located in the U-shaped area 200, and the water retaining structure 3 is a retaining plate, covering the water inlet 20. When injecting water, the water injected into the outer tub 2 from the water inlet 20 is blocked by the water retaining structure 3, and then flows along the inner flange 12 and the inner wall of the outer tub 2 to the bottom of the outer tub 2, or flows along the inner wall of the outer tub 2 to the bottom of the outer tub 2. At this time, the water retaining structure 3 has a simple shape, and only needs to block the water injected from the water inlet 20 from impacting the inner tub 1.

Specifically, when the water inlet 20 is located in the upper half of the outer cylinder 2, the injected water flows along the inner flange 12 and the inner wall of the outer cylinder 2 to the bottom of the outer cylinder 2 in sequence; when the water inlet 20 is located in the lower half of the outer cylinder 2, the injected water flows directly to the inner wall of the outer cylinder 2 under the action of gravity, and then flows along the inner wall of the outer cylinder 2 to the bottom of the outer cylinder 2.

More specifically, when the water inlet 20 is located in the upper half of the outer cylinder 2, the injected water needs to be diverted through the inner flange 12. At this time, it is set that during the steam washing process, the area on the inner flange 12 that first diverts the water flow first drops and then rises, so that the water attached to the inner flange 12 is scattered downward under the action of centrifugal force, thereby improving the safety of water injection.

Embodiment 6

The present embodiment provides a water injection structure of a clothing processing device, which differs from the second embodiment in that the water retaining structure 3 is connected to the outer side of the inner drum 1, and rotates with the drum during clothing processing. At this time, the water retaining structure 3 is annular, so that no matter where the inner drum 1 rotates relative to the outer drum 2, the water injection at the water inlet 20 can be blocked.
