DETAILED DESCRIPTION
[0024] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0025] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.
[0026] like Figures 1 to 4As shown, a preferred embodiment of the utility model provides a water guide structure for a washing machine, which includes a water guide 100 and a first protrusion 200, a second protrusion 301 pair 300 and a third protrusion 401 pair 401400 arranged from top to bottom, the first protrusion 200 includes an arc portion 201, a first bevel 202 and a second bevel 203 connected in sequence, the first bevel 202 and the second bevel 203 form a sharp corner 204, the water guide 100 is provided with a water inlet 101 and a plurality of water outlets 102, the arc portion 201 is close to the water inlet 101, and the sharp corner 204 is close to the water outlet 102. 02, the second protrusion 301 pair consists of two second protrusions 301 symmetrically arranged at left and right intervals, the third protrusion 401 pair consists of two third protrusions 401 symmetrically arranged at left and right intervals, the second protrusion 301 includes an upper arc 302, an arc edge 303, a lower arc 304 and a straight edge 305 connected in sequence, the third protrusion 401 includes an upper arc 402, an arc edge 403, a lower arc 404 and a straight edge 405 connected in sequence, the two straight edges 305 of the second protrusion pair 300 are vertically arranged, and the third protrusion pair 400 is arranged in an "eight" shape.
[0027] When water flows in from the water inlet 101, a main flow channel is formed. The main flow channel first passes through the first protrusion 200, wherein the arc portion 201 of the first protrusion 200 allows the main flow channel to flow along the first oblique edge 202 and the second oblique edge 203 to form two branch flow channels. The speed of the water flow is greater when passing through the arc portion 201, and is smaller when passing through the first oblique edge 202 and the second oblique edge 203. At the same time, when the two branch flow channels flow through the second protrusion pair 300, they first collide with the upper arc 302 of the second protrusion 301, where they are buffered and backflow is formed, so that the two branch flow channels on both sides are staggered and push each other here, which is for the subsequent water flow. The first protrusion 200, the second protrusion 301 and the third protrusion 401 provide power for the movement, so that the backflow can still be formed between the second protrusion pair 300 and the third protrusion pair 400, which can promote the movement of the water flow and ensure the flow rate of the water flow, thereby ensuring the water supply efficiency; in addition, due to the arrangement of the first protrusion 200, the second protrusion 301 and the third protrusion 401, the water flow can be guided, so that the water flow flows evenly to each water outlet 102 and then flows into the inside of the washing machine, so that the laundry detergent and softener can be fully integrated with the water flow; the use of the utility model can make the water flow at various places on the guide plate uniform, and the flow rate at various places uniform, thereby ensuring the water supply efficiency, thereby reducing the water filling time and reducing the power consumption.
[0028] It can be understood that this solution adopts the principle of the Tesla valve. When water flows through, it will enter along the two branch channels formed between the first protrusion 200, the second protrusion 301 and the third protrusion 401. In the further water flow transmission process, the water flow will be divided into two parts in different directions. This diversion makes the water flow produce a vortex flow under the action of centrifugal force.
[0029] It should also be noted that by setting the arc edge 303, the speed of water flowing through the arc edge 303 can be increased. Even if there is no backflow between the second protrusion pair 300 and the third protrusion pair 400 to gather water flow to provide downward pushing force, the water flow velocity of the arc edge 303 will not be reduced.
[0030] Exemplarily, the pointed corner 204 points to the interval area between the second protrusions 301 and 300. Thus, the pointed corner 204 can guide the main flow channel and ensure that part of the water flow can be smoothly guided to the middle area between the two second protrusions 301, thereby ensuring uniform water flow.
[0031] Specifically, the upper end spacing width of the third protrusion pair 400 is smaller than the distance between the two second protrusions 301 of the second protrusion pair 300. Thus, when the water flows through the third protrusion 401, it can be smoothly and evenly distributed on the third protrusion 401, rather than being concentrated in the middle of the third protrusion pair 400, further ensuring the uniformity of the water flow.
[0032] Exemplarily, the upper end spacing width of the third protrusion pair 400 is smaller than the lower end spacing width of the third protrusion pair 400 .
[0033] Exemplarily, in order to ensure the guiding effect on the water flow, the area of the upper arc 302 is larger than the area of the lower arc 304 .
[0034] Exemplarily, the water guide 100 includes a first flow guide area 103 and a second flow guide area 104 , the first flow guide area 103 and the second flow guide area 104 are arranged left and right, and the volume of the first flow guide area 103 is larger than that of the second flow guide area 104 .
[0035] In this embodiment, the first guide area 103 includes a pair of the second protrusions 301 300 and two pairs of the third protrusion pairs 400 , the second guide area 104 includes two pairs of the second protrusion pairs 300 and two pairs of the third protrusion pairs 400 , and the second protrusion pairs 300 and the third protrusion pairs 400 are arranged alternately.
[0036] It can be understood that the arc distance of the arc edge 303 of the second protrusion pair 300 located at the top is the largest; in the same time, when the same amount of water passes through, the longer the arc distance passed, the greater the speed, so the speed of water flowing through the top second protrusion 301 pair 300 is the largest, which can ensure that the water flow has sufficient power, thereby ensuring that the water flow smoothly flows to the water outlet 102.
[0037] Exemplarily, in order to further ensure uniformity of water outlet, the plurality of water outlets 102 are evenly arranged on the water guide 100 .
[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
