Description

A drum washing machine

technical field

The utility model relates to a drum washing machine.

Background technique

There are two kinds of washing machines currently on the market, one is to rely on the rotation of the pulsator at the bottom of the washing tub to clean clothes; the other is to clean clothes by the rotation of the drum. No matter which type of washing machine, there is a spray device. During the washing and rinsing cycle, the spray device can spray the clothes inside the drum to promote the quick wetting of the clothes, accelerate the decomposition of dirt, and increase the washing effect of the washing machine. In addition, it can quickly eliminate foam during washing and improve rinsing efficiency. There are many kinds of spraying devices of existing drum washing machines, such as Chinese patent: "A spraying device for drum washing machines (CN99220855.6)", which arranges a circulating water pipeline between the bottom of the washing tub and the observation window pad, Install the nozzle on the top of the observation window pad through the circulating water pump and pipe fittings, where the nozzle is installed on the observation window pad through nuts. There is also someone who fixes the spray port on the water tank, but also fixes it by external components such as screws. This fixing method requires connectors, and the cost is relatively high, and the range of spraying is also limited. Moreover, the assembly time is also increased by connecting through the connectors, and the production efficiency is affected to a certain extent.

Contents of the invention

The utility model mainly provides a drum washing machine which is integrally formed with a spray port and a water tank, has a simple structure and high production efficiency; it solves the problem that the spray port in the washing machine in the prior art needs to be fixed on the water tank through a connecting piece, High cost and low production efficiency are technical problems.

The utility model also provides a washing machine capable of forming a three-dimensional spraying effect, which is beneficial to the uniform distribution of washing water and has a good washing effect; it solves the problem that the spraying range of the spraying device in the washing machine in the prior art is small, Technical problem with poor washing effect.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a drum washing machine, comprising a water tank arranged in the washing machine, a drum is arranged in the water tank, and a drum is arranged on the water tank. A spray port for spraying water to the interior of the drum is opened from the front of the drum, and the spray port is an integral component with the tub. The spray port and the bucket are manufactured in one piece, the structure is simple, the assembly time is reduced, and the production efficiency is improved. At the same time, the connecting piece for fixing is omitted, which reduces the cost.

The number of spray outlets can vary according to different washing requirements. As a preference, there is one spray port, and one end of the spray port is connected to a washing water passage provided on the tub, and the washing water passage passes through the raised water inlet on the tub and the spray soft The pipes are connected, and the spray hose is arranged on the outside of the bucket, and the spray hose is connected to the solenoid valve. The spray port is toward the inside of the drum, and the washing water passage connecting the spray port is arranged on the end face of the water tub, which is ring-shaped. The electromagnetic valve controls the input of the washing water, and the washing water is sprayed into the drum through the spray hose and the washing water passage through the spray port.

As another preference, there are at least two spray outlets, which are evenly distributed on the end face of the tub, and a flow divider is provided above the bucket, and the flow divider includes an inlet and At least two outlets, the inlet of the diverter is connected to the solenoid valve through the spray hose, the outlet of the diverter is connected to the raised water inlet on the tub, and the water inlet is connected to the washing water channel on the end face of the tub , the washing water channel is connected to the spray port. A three-dimensional spraying effect can be formed by arranging a plurality of spraying ports on the end face of the bucket. Multiple spray outlets are located at different heights and positions. Under approximately equal water pressure, the spray outlets at different heights spray wash water at different longitudinal distances, and the spray outlets at different horizontal positions spray wash water at different lateral positions. , so the three-dimensional spraying effect can be realized in the inner space of the entire drum. A flow divider is fixed above the water bucket, which can simplify the structure, wherein the water inlet is connected with the electromagnetic valve, and several outlets correspond to several spray ports.

Preferably, the spray outlets are evenly distributed on the upper semicircular end surface of the water tub to form a fan-shaped distribution surface, and the angle range of the distribution surface is 90°-150°. The spray outlet is mainly arranged above the water tank, which is more conducive to forming a three-dimensional spray effect. The formed fan-shaped distribution surface is symmetrically distributed with the vertical diameter on the end surface of the water bucket as the center line.

Preferably, the spray opening is arc-shaped, and the angle between the opening direction of the spray opening and the horizontal line is α. If there are multiple spray ports, the shapes of the multiple spray ports can be different, and the angles between them and the horizontal line can also be multiple, and the range of the included angles is between 0-180 degrees, so as to form a better three-dimensional spray. shower effect.

Therefore, since the spray port of the utility model is integrally formed with the water tank, the structure is simple, the cost is low, the assembly time is reduced, and the production efficiency is improved; At different heights and positions, under approximately equal water pressure, the nozzles at different heights spray the washing water at different longitudinal distances, and the nozzles at different horizontal positions spray the washing water at different lateral positions, so the inner space of the entire drum can be Realize the three-dimensional spray effect.
