Problems solved by technology

Since the existing water inlet is just a simple large-diameter pipe, the condensed water is in the shape of a water column when it enters, and the contact area with the hot and humid air is relatively small, and the water flow is fast, and the residence time in the drying tunnel is relatively short, so the condensation efficiency is low. The drying process consumes water, time and electricity, which increases the user's use cost

Embodiment 1

[0085] The rotary spray head 20 includes: a stopper and a spray head main body 22, such as Figure 1 to Figure 3 shown. Wherein, the limiting member is supported on the top of the nozzle base 10; the nozzle base 10 is hollow inside, and the upper end of the nozzle body 22 passes through the nozzle base 10 and is fixedly connected with the limiting member, as Figure 4 to Figure 7 As shown, and can rotate relative to the shower head base 10 , the lower end of the shower head body 22 is provided with a nozzle 24 .

[0086] The nozzle base 10 is hollow inside, forming a cylindrical structure with both ends open; The function cannot enter the interior of the nozzle base 10; the upper end of the nozzle body 22 passes through the nozzle base 10 and is fixedly connected with the stopper, realizing the assembly of the rotating nozzle 20 and the nozzle base 10; and the nozzle body 22 can be opposite to the nozzle base. 10 rotates, so it can drive the stopper to rotate synchronously, ...

Embodiment 2

[0101] The difference with Embodiment 1 is that: on the basis of Embodiment 1, a connecting pipe 23 is provided on the outer wall of the rotary spray head 20, such as Figure 1 to Figure 3 As shown, one end of the connecting pipe 23 communicates with the inner space of the rotary spray head 20, and the other end is closed and arranged. The nozzle 24 is arranged on the connecting pipe 23 and communicates with the connecting pipe 23, as Figure 5 to Figure 7 shown.

[0102] Connecting pipe 23 is set on the outer wall of rotating shower head 20, and connecting pipe 23 has increased the radial dimension of rotating shower head 20, because one end of connecting pipe 23 communicates with the inner space of rotating shower head 20, and the other end is closed, thereby nozzle 24 Set on the connecting pipe 23, the condensed water needs to enter the nozzle 24 through the connecting pipe 23 and then spray out. This has not only further increased the spraying radius of the spraying device ...

Embodiment 3

[0118] The difference with the second embodiment is that: on the basis of the second embodiment, a sealing groove 12 is further provided on the outer wall of the nozzle base 10, such as Figure 13 with Figure 18 As shown, the spraying device 1 further includes a seal 30 installed in the sealing groove 12 for sealing the gap between the spray head base 10 and the drying tunnel 2 .

[0119] Sealing groove 12 is set on the outer wall of shower head base 10, and sealing member 30 (such as rubber sealing ring) is installed in sealing groove 12, then sealing member 30 can seal the gap between shower head base 10 and drying channel 2, guarantees The sealing reliability between the spraying device 1 and the drying tunnel 2 is improved, and water leakage between the spraying device 1 and the drying tunnel 2 is prevented, causing other components in the washing machine to be adversely affected.

[0120] In some embodiments of the present invention, the connecting portion is an externa...

Abstract

The invention provides a sprinkler and a washing machine. The sprinkler comprises a spray head base provided with a connection portion connected with a drying tunnel and a rotary spray head rotatablymounted on the spray head base and provided with a spraying nozzle communicated with a water inlet; the axis of the spraying nozzle extends obliquely with respect to the radial direction of the rotaryspray head so that the rotary spray head can self-rotate with respect to the spray head base under the counter force of water flow. According to the sprinkler, the sprinkler is added at the water inlet of the drying tunnel of the washing machine, the sprinkler is used for automatically spraying water in the circumferential direction, condensed water can be dispersed and sprayed into the drying tunnel, a good shunting effect is achieved, the spray area of the condensed water is significantly enlarged, the flow speed of the condensed water is reduced, thereby increasing the residence time of the condensed water in the drying tunnel, the condensed water can fully exchange heat with hot and humid air, thereby improving the condensation efficiency, and the effects of saving water, time and electricity are achieved.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a spray device and a washing machine including the spray device. Background technique [0002] At present, washing machines with drying function usually use condensation to realize the drying function. A water inlet is set on the drying tunnel, and condensed water is injected into the drying tunnel through the water inlet to exchange heat with hot and humid air to cool the air and condense the water vapor inside. Then dry air is sent into the inner bucket to take away the moisture in the clothes to realize the drying function. Since the existing water inlet is just a simple large-diameter pipe, the condensed water is in the shape of a water column when it enters, and the contact area with the hot and humid air is relatively small, and the water flow is fast, and the residence time in the drying tunnel is relatively short, so the condensation efficiency is low. The dryin...
