Description

Filter equipment and washing machine

Technical Field

The invention relates to a self-cleaning washing machine in the field of washing equipment, in particular to a filtering device and a washing machine.

Background

With the improvement of living standard of people, a washing machine is one of the main household appliances in daily life, the washing process of the washing machine mainly comprises several stages of washing, rinsing and spin-drying, the washing machine enters water and detergent to wash clothes in the washing stage, after the washing stage, in order to rinse stains and residual detergent, more water needs to be fed or more rinsing times needs to be carried out to rinse the clothes, which consumes a large amount of water resources, even though the washing machine is a water-saving drum washing machine, the washing machine needs to be rinsed at least twice for rinsing the clothes, and the process consumes at least more than 30L of tap water. Sometimes, the clothes are less in stain or less in detergent, and the clothes can be rinsed clean twice, but since the user selects 3 times of rinsing, waste of water resources is caused, for example, the water consumption of twice rinsing water of a 6Kg full-automatic washing machine is about 100 liters. How to save water and electricity while washing clothes is one of the focuses of consumers.

Until now, no water purification and recycling device matched with a household washing machine exists, even if the washing machine with a water-saving function is used, a water storage tank is generally arranged at the side position of the washing machine, a water pump is adopted for water injection and drainage, and water can be generally injected once and rinsed for 3 times to achieve the water-saving function. However, the washed water cannot be stored, and the washing machine has a complex and bulky structure, which is not favorable for transportation, recovery and treatment. Due to the limitations of volume, structure, flexibility and the like, the original functions of the washing machine and the functions of the water-saving tank are fully exerted.

On the basis of the existing washing mode, in order to save water resources better, a lot of manufacturers invest a lot of research and development to produce washing machines with water purification and recycling devices and water saving functions.

Meanwhile, as the flocculation technology is gradually mature, the flocculation technology is gradually applied and popularized in the industrial field. The water-saving washing machine manufactured by adopting the flocculation principle also becomes a research and development hotspot of various washing machine manufacturers. However, the conventional filtering apparatus causes a large amount of flocs to adhere to the filter screen along with the operation of the filtering program, and the filtering efficiency of the filtering apparatus is reduced; meanwhile, flocculate filtered and retained in the filtering device is inconvenient to clean and is not suitable for being directly utilized in the field of washing equipment.

In view of the above, the present invention is particularly proposed.

The opening of the groove 16 is provided with filter cotton 3 covering the opening. Thus, the part of the filter cavity 1 at the upper part of the filter cotton forms the cavity 4 to be filtered, and the hollow part of the groove 16 at the lower part of the filter cotton 3 forms the filtered cavity 5.

The side wall of the groove 16 is provided with a horizontal supporting rib 6 extending towards the inside of the groove 16. Preferably, the supporting ribs 6 are arranged around the side wall of the groove 16. It is further preferred that the outer circumference of the supporting rib 6 is connected to the upper side wall of the groove 16 such that the supporting rib 6 is disposed near the opening of the groove 16. The groove 16 has a large circumference at the upper opening and a small circumference at the lower opening.

The supporting ribs 6 are provided with supporting plates 7, the outer diameter of each supporting plate 7 is larger than the inner diameter of each supporting rib 6 and smaller than or equal to the outer diameter of each supporting rib 6, and the supporting plates 7 are just placed above the supporting ribs 6. The filter cotton 3 is placed in the groove 16 above the support plate 7. At least the middle part of the supporting plate 7 is in a grid shape, so that the flocculated water flows into the lower filtered cavity 5 after passing through the grid holes of the filter cotton 3 and the supporting plate 7 in sequence.

The filter cotton 3 which is overlapped above the supporting plate 7 is arranged at the opening of the covering groove 16; preferably, the upper side of filter pulp 3 sets up with the open end face parallel and level of recess 16 to avoid filter pulp 3 to bulge the recess opening setting, cause the emergence of the filtration efficiency reduction condition of flocculation water.

Therefore, through the arrangement, the filter cotton in the filter cavity adsorbs flocculate in the flocculated water, so that the flocculated water is filtered, and the aim of obtaining clean washing water is fulfilled.

In this embodiment, the bottom plate 11 of the filter chamber 1 is gradually inclined downward from the periphery to the opening of the groove 16, so that the flocculated water in the chamber 4 to be filtered flows into the groove 16. The water outlet 13 is arranged at the lowest position of the groove 16, so that the filtered clean water in the groove 16 is gathered and flows to the water outlet 13. Preferably, the bottom of the groove 16 is gradually inclined downwards from the first side to the opposite second side, and the water outlet 13 is arranged at the connecting position of the groove side wall of the second side and the groove bottom.

In this embodiment, the water inlet 12 is arranged at the upper part of the chamber 4 to be filtered; preferably, the water inlet 12 is provided in a side wall near the top of the filter chamber 1.

In this embodiment, the sidewall of the chamber 4 to be filtered is provided with a water overflow port 14. The overflow port 14 is higher than the filter cotton 3 and lower than the water inlet 12. The overflow port 14 is communicated with the flocculation treatment unit through an overflow pipe 15, so that the flocculation water to be filtered which is remained in the to-be-filtered cavity 4 flows back to the flocculation treatment unit, the excessive amount of the to-be-filtered water remained in the to-be-filtered cavity 4 is prevented, and the overflow condition of the to-be-filtered water from the upper cover at the top of the filter cavity 1 is avoided.

Meanwhile, when the rinsing of the washing machine is finished, rinsing water flows into the flocculation treatment unit and the filtering device, and because the rinsing water has a large flow rate, the filtering device is full of the rinsing water, flocs remained in the filtering device flow into the flocculation treatment unit through the overflow port, and flow out of the washing machine through a drain outlet arranged on the flocculation treatment unit. Thus, the effect of self-cleaning the filter device by using the rinsing water is realized.

Example two

As shown in fig. 1 to 4, in the present embodiment, the housing of the filter device further constitutes a storage chamber 2 provided independently of the filter chamber 1. A plurality of filter cottons 3 are stored in the storage chamber 2 to be replaced by the filter cottons in the filter cavity. The cover plate at the top of the storage chamber is detachable, so that the filter cotton in the storage chamber can be conveniently taken and placed.

Thus, after the filter cotton in the filter chamber is permeated with water and lowered, the user can take out the stored filter cotton in the storage chamber to replace the filter cotton in the filter chamber.

Preferably, the overflow pipe is provided with a flow sensor (not shown in the attached drawings), when the overflow flow rate detected by the flow sensor reaches a set value, the water feeding to the filter cavity is stopped, and an alarm signal is sent out to remind a user to replace the filter cotton in the filter cavity.
