AI Technical Summary
In the existing technology, the water distribution valve is required to achieve the switching between two layers of cleaning, which increases the product cost.
Design a volute structure including a first housing and a detachable second housing. By changing the connection method between the second housing and the installation port, the outlet can be manually switched. Single-layer or full-cavity washing can be achieved by using a baffle to block or unblock the baffle.
By changing the volute structure, the dishwasher can switch between single-layer and full-cavity washing without the need for a water distribution valve, thus reducing manufacturing costs.

TECHNICAL FIELD
[0001] The utility model relates to a volute for water pump, and further relates to a water pump with the volute. BACKGROUND
[0002] At present, in order to improve the cleaning capacity, the dishwashers on the market are often provided with a double-layer structure, the upper and lower layers are provided with dish racks, and the middle part is a partition plate, so that single-layer cleaning and upper and lower layer simultaneous cleaning can be realized; in order to realize the switching of the two cleaning modes, a water distribution valve is added to the outlet direction of the volute of the water pump, and different cleaning conditions are realized by controlling the water distribution valve. In the time sequence of double-layer cleaning, the water distribution valve is opened to realize overall cleaning of the dishwasher; only the lower layer is cleaned, the upper and lower layers are separated by the partition plate, only the lower layer is cleaned, and the cleaning time is reduced, so that the energy consumption is reduced. The water distribution valve requires a certain cost, thereby increasing the product cost. SUMMARY
[0003] The first technical problem to be solved by the utility model is to provide a volute with a water outlet that can be manually switched.
[0004] The second technical problem to be solved by the utility model is to provide a water pump with a water outlet that can be manually switched.
[0005] The technical scheme adopted by the utility model to solve the first technical problem is as follows: a volute, characterized by comprising a first shell body and a second shell body which is detachably assembled with the first shell body, the first shell body has a water inlet, a first water outlet and a second water outlet in the lateral direction, and a mounting port at the upper end, the first end face of the second shell body has a first connecting part capable of being sealingly connected with the mounting port and a baffle capable of shielding the inner end of the first water outlet, and the second end face of the second shell body has a second connecting part capable of being sealingly connected with the mounting port.
[0006] Further, the second end face is located at the back of the first end face.
[0007] As a preferred, the water inlet is arranged at the middle part of the second shell body.
[0008] As a preferred, the water outlet direction of the first water outlet and the water outlet direction of the second water outlet are consistent with the tangential direction of the volute.
[0009] As a preferred, the baffle is arc-shaped.
[0010] The connecting assembly of the first shell body and the second shell body is preferably provided as follows: the mounting port of the first shell body has a threaded part, and correspondingly, the first connecting part and the second connecting part have threads capable of being connected and assembled with the threaded part.
[0011] The utility model discloses a pump which comprises a pump body, an impeller and a volute.
[0012] Compared with the prior art, the utility model has the advantages that when the first end surface of the second shell is connected and assembled with the mounting port, the baffle will block the first outlet, so that water flow only flows out from the second outlet, realizing single-layer washing of the partition plate of the dishwasher. BRIEF DESCRIPTION OF DRAWINGS

[0017] The utility model will be described further in detail in combination with the drawings.
[0018] As shown in Figure 1 and Figure 2 , the water pump in the embodiment comprises a pump body 1, an impeller 2 and a volute 3, the impeller 2 is located in the volute 3 and is connected with the main shaft 11 of the pump body 1. The pump body 1 in the embodiment can adopt a motor.
[0019] The volute 3 comprises a first shell 31 and a second shell 32 which is detachably assembled with the first shell 31 as a whole, the first shell 31 has a water inlet 313, lateral first and second water outlets 311 and 312 and an upper mounting port 315, the water inlet 313 is arranged at the middle position of the second shell 32. The water outlet directions of the first and second water outlets 311 and 312 are 90°. The water outlet directions of the first and second water outlets 311 and 312 are consistent with the tangential direction of the volute 3.
[0020] The second shell 32 has a first end surface 321 and a second end surface 324, the second end surface 324 is located at the back of the first end surface 321. The first end surface 321 has a first connecting part 322 capable of being sealingly connected with the mounting port 315 and a baffle 323 capable of shielding the inner end of the first water outlet 311, the baffle 323 is arc-shaped. The second end surface 324 has a second connecting part 325 capable of being sealingly connected with the mounting port 315.
[0021] The mounting port 315 of the first shell 31 has a threaded part 314, correspondingly, the first connecting part 322 and the second connecting part 325 have threads capable of being connected and assembled with the threaded part 314.
[0022] In combination Figure 3 As shown, when the first end surface of the second shell is connected and assembled with the mounting port, the baffle will shield the first outlet, so that the water flow only flows out from the second outlet, realizing the single-layer washing of the partition of the dishwasher. When the full-cavity washing is needed, the second shell is disassembled, the second end surface of the second shell is connected and assembled with the mounting port, as shown Figure 4 As shown, since there is no shielding of the baffle, the water flow can flow out from the first water outlet and the second water outlet at the same time, realizing the full-cavity washing of the dishwasher. Only by changing the structure of the volute, the outlet of the volute is changed, and then the switching between the single-layer washing of the partition and the full-cavity washing can be realized, without the need of a water distribution valve, greatly reducing the manufacturing cost.
