Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an outer drum cover of a pulsator washing machine and the pulsator washing machine. Background Art

[0002] In the prior art, pulsator washing machines are common household washing appliances. The use and distribution of laundry detergent in these machines is directly related to the washing effect and efficiency of the detergent. However, current pulsator washing machines have a common problem with using detergent: users typically pour the detergent directly into the washing tub. Due to the dynamic distribution of water flow and clothing within the tub, the detergent often has difficulty distributing evenly across each piece of clothing. This can not only result in some clothes not being cleaned properly, but can also leave excess detergent residue on other clothes due to excess detergent, affecting wearer comfort and health. Furthermore, after being poured into the tub, the detergent takes a long time to completely dissolve in the water and effectively act on the stains on the clothes. This delayed dissolution not only prolongs the wash time but can also affect the final washing effect. Furthermore, some detergent is washed to the bottom of the pulsator during the initial wash cycle, preventing it from fully cleaning and resulting in wasted detergent. Due to insufficient mixing of the detergent and water, stains on the clothes may not be effectively softened, thus affecting the washing effect, especially when dealing with stubborn stains. Utility Model Content

[0003] Based on the technical problem of insufficient mixing of detergent and water and poor washing effect in the existing pulsator washing machine, the utility model provides a drum cover for the pulsator washing machine. By adding a diversion channel on the drum cover, the water flow is pressurized for a second time in the drum cover, which fully flushes the detergent in the detergent delivery chamber, thereby improving the utilization efficiency of the detergent and the mixing effect with the water flow, and significantly improving the washing effect.

[0042] Reference Figure 1-Figure 4 , which is an embodiment of the outer drum cover of the pulsator washing machine of the present invention.

[0043] The outer drum cover of a pulsator washing machine comprises an outer drum cover body 100 and a bottom cover 200 .

[0044] The outer tub cover body 100 is provided with a water inlet 110 connected to a water source.

[0045] The bottom cover 200 is disposed on the bottom surface of the outer tub cover body 100 . The bottom cover 200 is connected to the outer tub cover to form an inner cavity. The bottom cover 200 is provided with a water outlet.

[0046] A water inlet channel 132 , a detergent delivery chamber 135 and a water outlet chamber 136 are formed in the inner cavity.

[0047] The water inlet channel 132 is connected to the water inlet 110 , and is connected to the detergent delivery chamber 135 through the first diversion channel 133 , and is connected to the water outlet chamber 136 through the second diversion channel 134 .

[0048] The water outlet chamber 136 is connected to the detergent delivery chamber 135 and the water outlet.

[0049] In particular, the cross-sectional area of the first diversion channel 133 is smaller than the cross-sectional area of the water inlet channel 132 to ensure that the water flow can generate a higher flow rate when passing through the first diversion channel 133, which is conducive to the rapid dissolution and mixing of the detergent.

[0050] The outer drum cover of the above-mentioned pulsator washing machine, by adding a first diversion channel 133 with a smaller cross-sectional area on the outer drum cover, can make the water flow pressurized for a second time inside the outer drum cover, fully flush the detergent in the detergent delivery chamber 135, thereby improving the utilization efficiency of the detergent and the mixing effect with the water flow, and significantly improving the washing effect.

[0051] In this embodiment, at least one rotating wheel 140 driven by water flow is disposed in the water outlet cavity 136. When water flows through the water outlet cavity 136, the rotating wheel 140 is driven to rotate, further enhancing the mixing effect of the water flow and detergent and improving washing efficiency.

[0052] like Figure 4 As shown, tap water enters the outer drum cover through the water inlet 110. The arrow in the figure shows the direction of water flow. After entering the outer drum cover, the water flows in two directions. One direction passes through the second diversion channel 134 and flushes the wheel 140, causing it to rotate rapidly. The other direction passes through the first diversion channel 133 and is pressurized into the detergent delivery chamber 135, flushing the detergent in the chamber. The detergent in the chamber is brought to the wheel 140, and the wheel 140 rotates to fully mix with the water, and then flows into the inner drum through the water outlet. During the entire process, the water and detergent are pre-mixed twice. The first time is through the first diversion channel 133 to increase the water pressure, and the second time is through the wheel 140. The rapid rotation of the wheel 140 fully mixes the detergent and water, and finally flows into the inner drum of the washing machine.

[0053] In this embodiment, the outer cover body 100 has a hinge portion 120 hingedly connected to the tub lid, and the inner cavity is disposed at the rear side of the hinge portion 120. Positioning the inner cavity at the rear of the outer cover body 100 ensures that the structure within the inner cavity is not disturbed when the tub lid is opened or closed. Furthermore, the inner cavity can be designed to be larger than in other locations, thereby improving water intake efficiency.

[0054] The bottom surface of the outer cover body 100 is provided with several guide ribs, which divide the inner cavity into a water inlet channel 132, a first diversion channel 133, a second diversion channel 134, a detergent dispensing chamber 135, and a water outlet chamber 136. The guide ribs are formed on the bottom surface of the outer cover body 100 and have a simple structure.

[0055] Specifically, if Figure 3 As shown, the plurality of guide ribs include a first guide rib 151 , a second guide rib 152 and a third guide rib 153 .

[0056] The first guide rib 151 is located between the water inlet 110 and the water outlet, and together with the inner wall of the inner cavity, forms a water inlet chamber 131 and a water outlet chamber 136. The water outlet chamber 136 is arranged in front of the water inlet chamber 131, and the detergent dispensing chamber 135 is located on one side of the water inlet chamber 131 and the water outlet chamber 136.

[0057] The second guide rib 152 extends along the water inlet 110 toward the detergent delivery cavity 135 . The second guide rib 152 and the inner cavity sidewall form a water inlet channel 132 , and the water inlet channel 132 is connected to the water inlet cavity 131 .

[0058] The third guide rib 153 is located between the second guide rib 152 and the detergent dispensing cavity 135. It is an arc-shaped structure with an opening. The second guide rib 152 extends to the opening of the third guide rib 153. The outer wall of the third guide rib 153 and the inner cavity side wall form a first diversion channel 133, and the inner side of the third guide rib 153 forms a second diversion channel 134.

[0059] In this embodiment, the water inlet 110 is disposed on the front-rear center axis of the tub cover body 100 .

[0060] The outer tub cover body 100 is provided with a detergent injection port, which is communicated with the detergent injection cavity 135. The user can conveniently add detergent through the detergent injection port without opening the entire outer tub cover.

[0061] See also Figure 1 The detergent inlet is provided with a detergent box cover 300, which can be moved to close or open the detergent inlet. The design of the detergent box cover 300 prevents accidental leakage of detergent and keeps the washing machine clean.

[0062] The detergent box cover 300 is rotatably mounted on the detergent inlet, and the detergent box cover 300 is rotated to open or close the detergent inlet. The rotating design of the box cover allows the user to easily operate the detergent box cover 300, thereby improving the convenience of use.

[0063] The present invention also includes a pulsator washing machine including the aforementioned drum cover. By adding a first diversion channel 133 having a smaller cross-sectional area to the drum cover, water can be pressurized a second time within the drum cover, fully flushing detergent within the detergent delivery chamber 135. This improves detergent utilization efficiency and mixing with water, significantly enhancing washing performance.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
