[0007] A pump is installed at the connection between the input end of the transverse passage and the lower end of the water collection hopper, the impeller of the pump faces the water collection hopper, and the central axis of the impeller is perpendicular to the extension direction of the transverse passage.

[0008] A valve body, at least partially disposed at the connection between the output end of the transverse passage and the longitudinal passage, is used to control the opening and closing of the fluid passage.

[0009] Furthermore, there is a gap between the impeller and the inner top wall of the connection between the transverse passage input end and the lower end of the water collecting hopper, forming a flow channel.

[0010] Furthermore, the height of the flow channel is 1 / 4 to 1 / 3 of the height of the transverse passage.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] like Figure 1-4 As shown, the residue-free strong drainage device for cleaning equipment described in this embodiment of the present invention includes a housing 100, a pump 200, and a valve body 300. Wherein,

[0031] The housing 100 is provided with a water collection hopper 101, which is used to connect to the drain outlet of the cleaning equipment. The specific structure can be as follows: the water collection hopper 101 is a circular water collection tank with an integrated drain pipe 109 at its lower end and a screw seat 110 on its outer peripheral surface. The water collection hopper 101 is sealed to the drain outlet of the cleaning equipment and is fixed to the cleaning equipment by screws passing through the screw seat 110.

[0032] The housing 100 has mutually perpendicular transverse passages 102 and longitudinal passages 103 inside. The input end of the transverse passage 102 is connected to the lower end of the water collecting hopper 101, and the output end is connected to the longitudinal passage 103, forming a fluid channel. Specifically, the housing 100 can be equipped with a transverse pipe 107 (which internally forms the transverse passage 102) and a longitudinal pipe 108 (which internally forms the transverse passage 102). The input end of the transverse pipe 107 is connected to the lower end of the water collecting hopper 101. The output end is vertically connected to the upper end of the longitudinal pipe 108 to form the fluid channel inside the housing 100. Moreover, the water collection hopper 101, the transverse pipe 107 and the longitudinal pipe 108 preferably adopt an integrated structure. For example, the water collection hopper 101, the transverse pipe 107 and the longitudinal pipe 108 are integrally cast or injection molded. On the one hand, this ensures the smoothness of the fluid channel surface, ensuring that the residue and water are discharged smoothly together, avoiding the accumulation of residue at the joints of the fluid channel in existing drainage devices. On the other hand, it greatly simplifies the structure of the device and significantly improves the assembly efficiency.

[0033] The pump 200 is located at the connection between the input end of the transverse passage 102 and the lower end of the water collection hopper 101. The impeller 201 of the pump 200 faces the water collection hopper 101, and the central axis of the impeller 201 is perpendicular to the extension direction of the transverse passage 102. The valve body 300 is at least partially located at the connection between the output end of the transverse passage 102 and the longitudinal passage 103, and is used to control the opening and closing of the fluid passage. The specific structure can be as follows: a first assembly cavity 105 is provided at the connection between the input end of the transverse passage 102 and the lower end of the water collection hopper 101 (i.e., the drainage pipe 109); a second assembly cavity 106 is provided at the connection between the output end of the transverse passage 102 and the longitudinal passage 103; the impeller 201 of the pump 200 is disposed in the first assembly cavity 105; and the valve plug of the valve body 300 is disposed in the second assembly cavity 106 to control the opening and closing of the second assembly cavity 106. Preferably, the valve body 300 is an electromagnetic valve. The valve plug 301 and the valve core 302 of the electromagnetic valve are coaxial with the transverse passage 102, and the movement direction of the valve plug 301 is consistent with the direction of the transverse passage 102 and can block the transverse passage 102. Compared with the existing drainage device using a direct pull check valve, the structure is simple, the performance is stable and reliable, and the volume of the drainage device is reduced, thereby reducing the limitation of installation space and improving versatility.

[0034] When the residue-free strong drainage device of the cleaning equipment described in this utility model is working, the valve body 300 opens, opening the fluid channel. At the same time, the pump 200 starts, and the impeller 201 rotates, causing the water at the connection between the input end of the transverse passage 102 and the lower end of the water collection hopper 101 to form a vortex. The vortex water flow enhances the drainage intensity on the one hand, and cleans the water collection hopper 101 (and even the drain outlet of the cleaning equipment) on the other hand, thereby achieving residue-free strong discharge of the cleaning equipment. Moreover, the rotating impeller 201 and the transverse passage 102 are on the same straight line, which propels the water flow and further improves the strong drainage performance. Furthermore, by using a fluid channel formed by mutually perpendicular transverse passage 102 and longitudinal passage 103, the overall height is reduced compared with existing drainage devices, further reducing installation space limitations and increasing versatility. In addition, by setting the valve body 300 at the fluid channel behind the pump 200, it is avoided that residue will accumulate due to water backflow to the impeller 201.

[0035] like Figure 2 As shown, in a preferred embodiment of this utility model, there is a gap between the impeller 201 and the inner top wall of the connection between the input end of the transverse passage 102 and the lower end of the water collecting hopper 101, forming a flow channel 104. Preferably, the height of the flow channel 104 is 1 / 4 to 1 / 3 of the height of the transverse passage 102. This flow channel 104 ensures that residue and water in the vortex flow can smoothly flow into the transverse passage 102 and be discharged, reducing the risk of residue getting stuck on the impeller 201 and further improving the residue-free forced discharge performance of this device.

[0036] like Figure 5 and 6 As shown, in another preferred embodiment of this utility model, the motor shaft 202 of the pump 200 is provided with a first connecting part 203, the impeller 201 is provided with an assembly cavity 204, and a second connecting part 205 is provided in the assembly cavity 204. When the assembly cavity 204 of the impeller 201 is assembled on the motor shaft 202, the second connecting part 205 and the first connecting part 203 are fastened to each other, so as to realize the quick assembly and disassembly of the impeller 201. The first connecting part 203 is a connecting sleeve mounted on the motor shaft 202, and its peripheral surface is provided with a first fastening part 206 and a second fastening part 207. The first fastening part 206 is a longitudinal fan-shaped locking block, and the left and right sides of the longitudinal fan-shaped locking block are provided with first longitudinal locking grooves 208. The second fastening part 207 is composed of two figure-eight distributed first longitudinal locking plates 209, and the opposite side surface of the two first longitudinal locking plates 209 is provided with a protruding first longitudinal locking strip 210. The second connecting part 205 includes a third fastening part 211 and a fourth fastening part 212. The third fastening part 211 is composed of two figure-eight distributed second longitudinal locking plates 213, and the opposite side surface of the two second longitudinal locking plates 213 is provided with a protruding first longitudinal locking strip 210. The side surface is provided with a raised second longitudinal retaining strip 214. The fourth fastening part 212 is a longitudinal fan-shaped retaining block. The left and right sides of the longitudinal fan-shaped retaining block are provided with second longitudinal retaining grooves 215. During assembly, the first fastening part 206 is assembled between the two second longitudinal retaining plates 213 of the third fastening part 211, and the first longitudinal retaining groove 208 is engaged on the second longitudinal retaining strip 214. The fourth fastening part 212 is assembled between the two first longitudinal retaining plates 209 of the second fastening part 207, and the second longitudinal retaining groove 215 is engaged on the first longitudinal retaining strip 210, so that the second connecting part 205 and the first connecting part 203 are fastened to each other, thereby installing and fixing the impeller 201 on the motor shaft 202. The whole process does not require the use of any tools, and the disassembly and assembly are convenient.

[0037] The cleaning equipment described in this utility model can be a dishwasher (such as a trough-type dishwasher or an embedded dishwasher), a washing tank, etc., and its drain outlet is connected to the aforementioned cleaning equipment with a residue-free strong drainage device.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
