Abstract
Description
Technical Field
[0001] The utility model is applied to the technical field of drainage pumps, and particularly relates to a water pump without a casing. Background Art
[0002] Washing machines, dryers and other equipment have made it possible to eliminate the need for manual washing and wringing of clothes, making people's lives more convenient. In order to dehydrate and dry the clothes, it is necessary to drain the excess water from the clothes first. The drainage process is achieved by generating negative pressure through a drainage pump, which then drains the excess water. A drainage pump usually consists of a pump body and a casing. The pump body is arranged inside the casing to protect the working parts of the pump body. The casing is provided with water inlets and outlets and is connected to the load compartment of the equipment. The water inlets and outlets need to be connected to pipes respectively to discharge the water in the load compartment to the outside of the equipment. In order to ensure stability during operation, traditional washing machines and dryers are usually designed to have a relatively large overall structure, so there is enough space for the installation of the water pump. However, with the current technological iterations in the industry, the degree of integration is getting higher and higher, and the volume design is miniaturized. The traditional drainage pump structure is too large to meet the existing integration requirements, and the limited space available for operation makes it inconvenient for assembly and maintenance.
[0003] If a water pump structure that can be quickly installed and highly integrated in conjunction with a water outlet pipe structure can be provided, the above-mentioned technical problems can be well solved. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a casing-less water pump which can be quickly installed and highly integrated.
[0005] The technical solution adopted by the present invention is: the present invention is connected in cooperation with the drainage pipe of the equipment container, the present invention includes a motor, a mounting plate and a pump blade, the motor is fixed on one side of the mounting plate, the pump blade is fixed on the mover of the motor and is located on the other side of the mounting plate, a limiting ring is provided on the mounting plate, a mounting hole is provided between the input end and the output end of the drainage pipe of the equipment container, a sealing ring is provided on the outer side of the limiting ring and is sealed with the mounting hole, and the pump blade is located in the drainage pipe of the equipment container when the mounting plate is matched with the mounting hole.
[0006] As can be seen from the above solution, the pump blades directly cooperate with the equipment container drain pipe, thereby eliminating the need for a housing during water pump production, improving production efficiency. Furthermore, during equipment assembly, there is no need to connect the inlet and outlet pipes separately as with traditional pumps with housings. Instead, only the mounting plate needs to be connected to achieve a sealed connection with the equipment container drain pipe, allowing for convenient and quick equipment assembly within a compact space. The pump blades operate within the equipment drain pipe to achieve pressurized drainage.
[0007] A preferred solution is that a connecting flange is provided on the outside of the mounting hole, and the mounting plate is connected to the connecting flange by bolts.
[0008] A further preferred solution is that the mounting hole is located on a side of the equipment container water pipe close to the equipment outer wall.
[0009] A further preferred solution is that a plurality of groups of latch blocks are arranged in a circumferential array on the mounting plate, and the latch blocks are limitedly engaged with the positioning holes on the connecting flange.
[0010] A preferred solution is that the pump blade includes an integrally formed connecting shaft and several blades, the connecting shaft is a stepped shaft, and the several blades are distributed in a circular array on the small diameter end of the connecting shaft, and one side of the several blades is connected to the large diameter end of the connecting shaft.

[0012] Figure 2 This is a second three-dimensional structural diagram of the present invention;
[0013] Figure 3 This is a third three-dimensional structural diagram of the present invention. DETAILED DESCRIPTION
[0014] like Figures 1 to 3 As shown, in this embodiment, the present invention is connected to the drainage pipe of the equipment container. The present invention includes a motor 1, a mounting plate 2, and a pump blade 3. The motor 1 is fixed to one side of the mounting plate 2, and the pump blade 3 is fixed to the mover of the motor 1 and is located on the other side of the mounting plate 2. A limit ring 21 is provided on the mounting plate 2. A mounting hole is provided between the input end and the output end of the drainage pipe of the equipment container. A sealing ring 22 is provided on the outer side of the limit ring 21 to seal with the mounting hole. When the mounting plate 2 is fitted with the mounting hole, the pump blade 3 is located in the drainage pipe of the equipment container. By providing the limit ring 21 and the sealing ring 22, the positioning and sealing of the mounting plate 2 and the mounting hole are achieved. The motor 1 drives the pump blade 3 to rotate in the drainage pipe of the equipment container, thereby generating negative pressure to discharge water in the equipment container from the drainage pipe.
[0015] In this embodiment, a connecting flange is provided on the outside of the mounting hole, and the mounting plate 2 is bolted to the connecting flange. The mounting hole is located on the side of the equipment container water pipe close to the equipment outer wall. The housingless water pump is secured with bolts, and during installation, the bolts are connected through the access port on the back of the washing machine or dryer. Compared to traditional housing water pump structures, only a single installation is required to complete the assembly process, eliminating the need for multiple connections to the water inlet and outlet pipes. Furthermore, the installation direction is convenient.
[0016] like Figure 3 As shown, in this embodiment, several groups of latch blocks 23 are arranged in a circumferential array on the mounting plate 2. These latch blocks 23 engage with the positioning holes in the connecting flange. This arrangement allows for quick alignment during assembly. Both sides of the latch blocks 23 are chamfered, providing guidance and preventive measures during docking.
[0017] In this embodiment, the pump impeller 3 includes an integrally formed connecting shaft 31 and a plurality of blades 32. The connecting shaft 31 is a stepped shaft, and the blades 32 are distributed in a circumferential array on the small-diameter end of the connecting shaft 31. One side of each of the blades 32 is connected to the large-diameter end of the connecting shaft 31. The integrally formed connecting shaft 31 and blades 32 ensure the reliability of the overall structure of the pump impeller 3. The stepped shaft structure provides multi-point support for the blades 32, improving the connection stability of the blades 32 and thereby extending their service life.
[0018] In this embodiment, a power supply connection slot is provided on the motor 1 , and the motor 1 is electrically connected to an external power supply line through the power supply connection slot.
[0019] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
