Description

Heating device for washing machine and washing machine

[ technical field ] A method for producing a semiconductor device

The utility model relates to a washing machine still relates to the heating device who adds hot water among the washing machine.

[ background of the invention ]

The bottom of the liquid holding tub of a washing machine is usually equipped with a heating device for heating the water during the washing process. The heating device generally comprises a heating tube which is formed by bending and coiling a thin tubular metal tube. The lint, cotton threads, and hair, etc. dropped from the laundry during the washing process, float in the liquid container along with the washing water.

The liquid containing barrel is internally provided with a rotary drum which is driven by a motor to rotate. The roller rotates in the washing process to drive water in the liquid containing barrel to flow and agitate. Foreign matters such as flocks in water can be wound on the heating pipe when passing through the heating pipe. The entangled lint may reduce the heating efficiency of the heating device one by one, affecting the performance of the washing machine.

[ Utility model ] content

One object of the present invention is to reduce the amount of lint that gets entangled on the heating tube.

In order to realize this purpose, the utility model provides a heating device for washing machine contains the mount pad and adorns the heating pipe on the mount pad, and wherein the heating pipe roughly is the plane and spreads for the neighbouring heating pipe of the member of catching batting is fixed in on the mount pad, the member with the heating pipe is with the plane, is located at least one side of heating pipe, and with the heating pipe interval sets up.

When the washing water flows through the heating device, the washing water firstly flows through the rod piece, and the lint in the water is blocked by the rod piece and is wound on the rod piece, so that the amount of the lint wound on the heating pipe is reduced, and the influence of the lint on the heating efficiency is reduced.

The optional improvement also comprises that the surface of the rod piece is provided with a floc catching device. The lint pickers may be adhesive surfaces, may be fine, uneven surfaces, and may include outwardly extending burrs. The fine fibrous materials such as flocks are easily caught by these catching means.

The utility model also provides a washing machine, this washing machine contain flourishing liquid bucket and be located the cylinder of flourishing liquid bucket, the cylinder receives motor drive and rotatable, as above heating device adorn in flourishing liquid bucket bottom.

The heating pipe and the rod piece are axially spread in parallel to the liquid containing barrel, wherein the mounting seat is arranged on the rear wall of the liquid containing barrel, and the rod piece axially extends along the liquid containing barrel. When the roller rotates, the water flow between the liquid containing barrel and the roller is driven to flow along the circumferential direction, and the water flow is approximately vertical to the rod piece. The lint is then caught by the rods before reaching the heating tube.

The washing machine comprises a control device which is arranged to control the motor to drive the drum to rotate along a first direction in a dehydration stage of a washing process, so that water flow mainly passes through the heating pipe along the first direction, and the rod piece is arranged on one side of the heating pipe facing to the water flow direction. The drum is typically rotated in only a single first direction during the dewatering process. During the period, the water flow flows in a high-speed one-way mode, which is the main stage of flock winding, and only the rod piece is arranged on one side, facing the flow direction of the water flow, of the heating pipe, so that the cost and the space can be saved, and meanwhile, the flock is mainly gathered on one side facing the flow direction of the water flow.

Wherein the first direction is, for example, clockwise when viewed from the bottom of the liquid container, and the rod member is disposed at the right side of the heating pipe when viewed from the bottom of the liquid container.

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.

[ description of the drawings ]

FIG. 1 is a schematic view of the main components of a washing machine;

fig. 2 is a top view of the heating device.

[ detailed description ] embodiments

As shown in fig. 1, the washing machine 100 has a tub 2 and a drum 4 located within the tub. The drum 4 is driven to rotate by a motor 6. The keg 2 and the drum 4 are arranged axially horizontally or, in other embodiments not shown in the figures, the keg 2 and the drum 4 are arranged obliquely with respect to the horizontal. A heating device 10 is mounted on the rear wall 21 of the keg 2. The heating device comprises a mounting base 11 and a heating pipe 12 arranged on the mounting base. The mounting seat 11 is mounted on the rear wall 21 of the liquid containing barrel 2, and the heating pipe 12 is positioned at the bottom of the liquid containing barrel 2 and is spatially positioned between the roller side wall 42 and the liquid containing barrel side wall 22.

The washing machine 100 further has a control device 8 electrically connected to the motor 6 and the heating device 10. In the washing process, under the control of the control device 8, the motor 6 drives the roller 4 to rotate at a low speed in the main washing and rinsing stages and at a high speed in the dehydration stage; in addition, under the control of control device 8, heating device 10 is switched on during the main wash and/or rinse phases to heat the water inside keg 2. Normally, the motor 6 rotates only in one direction during the spinning stage, and accordingly the drum 4 rotates only in the first direction a. The first direction is, for example, clockwise as viewed from the bottom of the keg 2. Thus, during the spin-drying phase, the water flow, which is carried along by the drum and is extracted from the laundry, flows through the heating pipe 12 in a first direction, i.e. from right to left when viewed from the bottom of the keg 2, through the heating pipe 12.

As shown in fig. 1 and 2, the heating pipe 12 is spread out in a substantially planar manner. A rod 14 for catching lint is fixed to the mounting 11 adjacent to the heating tube 12. The rod member 14 is coplanar with the heating tube 12 and both are spread substantially parallel to the axial direction of the keg 2. The rod member 14 is located on one side of the heating tube 12 and spaced apart from the heating tube 12. While the rod member 14 extends axially along the keg 2. It is also within the scope of the present invention to provide the rod members 14 on both sides of the heating tube 12. The rod 14 on one side of the heating tube 12 may also be desirable to capture lint if cost and space considerations are taken into account, but it is desirable to choose which side to locate.

Considering that the water flow during the dewatering phase is in the first direction a through the heating tube 12, the batt is most likely to entangle during the dewatering phase. The rod element 14 is then arranged on the side of the heating tube 12 facing the direction of the water flow, in the embodiment shown in fig. 1 and 2, the rod element 14 is arranged on the right side of the heating tube 12 as seen from the bottom of the keg 2.

In order to make the rod member 14 catch the lint better, the rod member 14 is provided with lint catching means 15 on its surface. In particular as a dense burr 15 as shown in fig. 2. The lint pickers may also be an adhesive surface, may be a fine uneven surface, or the like.

The various embodiments described above and shown in the drawings are illustrative of the invention and are not intended to be all-inclusive. In the scope of the basic technical idea of the present invention, a person skilled in the relevant technical field can easily change the position of the object to be protected.
