Description

The line pack housing structure of wet-pit

Technical field

The utility model relates to a kind of line pack arrangement, particularly relates to a kind of structure simple, the line pack housing structure of the wet-pit of easy accessibility.

Background technology

In existing washing machine structure, in order to discharge the sewage after washing clothes, wet-pit is generally installed at the water port place of washing machine, existing wet-pit structure generally comprises the pump housing of tubular, pump housing inner chamber is longitudinally divided into intake antrum and drain chamber, the sidewall of intake antrum there is water inlet pipe, the sidewall of drain chamber there is water shoot, there is motor drain chamber one end of the pump housing, the rotating shaft of motor is stretched in drain chamber and is coaxially connected with impeller, the support of motor side is provided with iron core, sheet is inserted in plastic packaging line bag and wiring, one end that sheet is inserted in wiring is connected with the coil output in plastic packaging line bag, two coil assemblies on U-shaped iron core leg wherein generally adopt independent staving to be set in outside two legs of stator core, independent installation need to be carried out when therefore installing, not only dismounting is wasted time and energy, and dimensional precision when installing cannot ensure, the normal operation of wet-pit is directly affected time serious.

Summary of the invention

It is simple that the utility model mainly provides a kind of structure, easy accessibility, the line pack housing structure of safe and reliable wet-pit, solve in prior art the split type line pack housing existed and need independent installation, not only dismounting is wasted time and energy, positioning precision cannot ensure, directly affects the technical problem of the normal operation etc. of wet-pit time serious.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the line pack housing structure of a kind of wet-pit, comprise annular case and envelope cover on the top cover on circular cowling shell opener end and bottom, annular case, top cover and bottom enclose receive coil space jointly, top cover and bottom are respectively equipped with one to interworking interting the upper shed groove of U-shaped iron core leg and lower opening groove, extend internally between the annular case corresponded between two upper shed grooves or two lower opening grooves and form the spacing groove of two the coil assemblies that can separate on U-shaped iron core leg. adopt the annular case of integral structure can be sleeved on outside the coil assembly outside U-shaped iron core leg simultaneously, and separate the coil assembly on U-shaped iron core two legs by the spacing groove on annular case, without the need to independent installation, simplify structure, low cost of manufacture, it is time saving and energy saving to dismount, and positioning precision when simultaneously installing is guaranteed, safe and reliable, thus further ensure quality product.

As preferably, the annular case both sides outside wall surface that described two coil arrangements of components directions are corresponding being respectively equipped with and the dop of wet-pit housing interworking. Annular case is connected in card groove corresponding to wet-pit housing by dop, and mode of connection is simple and reliable.

As preferably, the lower port front side horizontal of the annular case corresponding with described bottom outwards extends to form clamping plate, and clamping plate and bottom jointly enclose Thermal protection device and derive groove and some slotting sheet locating slots. Clamping plate and bottom jointly enclose to close and form Thermal protection device and derive groove and slotting sheet locating slot with stationary heat protector wiring end and slotting sheet, and fixing mode is simple and reliable.

As more preferably, the annular case outside wall surface deriving groove corresponding with described protector outwards extends to form Thermal protection device locating slot. By Thermal protection device locating slot grafting stationary heat protector, easy accessibility, fixing mode is simple and reliable.

As preferably, described annular case, top cover and bottom adopt flame retardant plastics injection moulding. Adopt flame retardant plastics, avoid overheated or short-circuit time cause spontaneous combustion, safe and reliable.

Therefore, the line pack housing structure of wet-pit of the present utility model has following advantage: the annular case of integral structure wraps outside two the coil assemblies covered on outside U-shaped iron core leg simultaneously, and by the spacing groove on annular case, the coil assembly on U-shaped iron core two legs is separated, without the need to independent installation, simplify structure, low cost of manufacture, it is time saving and energy saving to dismount, positioning precision when simultaneously installing is guaranteed, safe and reliable, thus further ensures quality product; Annular case is connected in card groove corresponding to wet-pit housing by dop, and mode of connection is simple and reliable; Be fixedly clamped Thermal protection device wiring end and slotting sheet by clamping plate and bottom, and fixing mode is simple and reliable.
