A drum opening of the outer drum has a clothes taking and placing opening. The inner drum is rotatably arranged in the outer drum and is used for containing clothes. The machine door is rotatably connected with the machine shell to open and close the clothes taking and placing opening. The machine door includes an observation window. A user can conveniently observe the washing and drying process of the washing and drying integrated machine through the observation window. The observation window also encloses a concave cavity with an opening facing the outside of the machine shell. A cavity bottom wall of the concave cavity is a plane. When the machine door is closed, part of the observation window extends into the clothes taking and placing opening to prevent the clothes from rubbing against the inner wall of the clothes taking and placing opening.

[0004] When the washing and drying integrated machine dries clothes, hot air flows into the space between the clothes taking and placing opening and the observation window from the top of the outer drum, and then directly blows onto the upper part of the inner drum.

[0040] Figure 1 A schematic diagram of a washing and drying integrated machine in the related art. Figure 1 A washing and drying integrated machine 100 in the related art is shown, which includes a cabinet 10, an annular window pad, an outer drum 20 arranged in the cabinet 10, and an inner drum 30 rotatably arranged in the outer drum 20. The cabinet 10 includes a front plate, and the front plate is provided with an opening. The drum top of the outer drum 20 (the left end in the figure) extends into the opening, and the annular window pad is mounted in the drum mouth of the outer drum 20 and the inner wall of the annular window pad surrounds a clothes taking and placing opening. The clothes taking and placing opening is in communication with the drum mouth of the inner drum 30, so that clothes can be placed into the inner drum 30 from the clothes taking and placing opening. Figure 1

[0041] The washing and drying integrated machine 100 also has a machine door, which includes an observation window 50, an inner frame and an outer frame in the shape of a ring. The inner frame surrounds the clothes taking and placing opening and is fixedly connected with the front plate. The edge of the observation window 50 is connected with the inner edge of the outer frame, so that the observation window 50 is mounted in the outer frame. The outer frame is rotatably connected with the inner frame through a hinge structure, and the observation window 50 can rotate with the outer frame to open and close the clothes taking and placing opening. The observation window 50 is made of transparent material, so that the user can observe the washing and protecting process of the washing and drying integrated machine 100 through the observation window 50. When the clothes taking and placing opening is closed, part of the observation window 50 extends into the clothes taking and placing opening, so as to prevent the clothes in the inner drum 30 from rubbing against the annular window pad and to prevent the water in the inner drum 30 from overflowing.

[0042] The washing and drying integrated machine 100 also includes a drying device 40 for drying clothes. The drying device 40 includes a drying air duct 41, a condenser 43, a heating pipe 44 arranged in the drying air duct 41, and a fan 42. The drying air duct 41 is arranged outside the outer drum 20. The drying air duct 41 has an air duct inlet and an air duct outlet. The air duct inlet is in communication with the gas outlet end of the condenser 43. The gas inlet end of the condenser 43 is in communication with the air outlet of the inner drum 30. The air duct outlet is in communication with the air inlet of the outer drum 20. The air inlet is arranged on the drum wall of one end of the drum mouth of the outer drum 20 (the left end in the figure), and the air outlet is arranged on the drum bottom of the inner drum 30 (the right end in the figure). Figure 1 Figure 1 ​​(The middle part is the right end). There is a cavity between the inner cylinder 30 and the outer cylinder 20. The air outlet is connected to the air inlet of the condenser 43 through the cavity. Under the action of the fan 42, the air circulates sequentially along the drying air duct 41, the air inlet, the outer cylinder 20, the inner cylinder 30, the air outlet, the cavity, and the condenser 43.

[0043] When the washer-dryer combo 100 is used to dry wet clothes, its working process is roughly as follows: Air flowing along the drying duct 41 passes through the heating element 44 and becomes hot air. The hot air flows into the flow gap between the observation window 50 and the annular window gasket through the air inlet. Then, the hot air is blown into the inner drum 30 from the drum opening. The hot air comes into contact with the wet clothes and becomes humid hot air. The humid hot air is discharged into the condenser 43, where the condenser 43 causes the humid hot air to condense water and become dry cold air. The dry cold air then flows back into the drying duct 41, thus starting the next cycle. In this way, the clothes can be dried.

[0044] However, from Figure 1 As can be seen, in the relevant technology, the inner bottom surface 52 of the observation window 50 facing the inner drum 30 is flat, and the side wall of the observation window 50 is annular. This will cause the hot air flowing into the flow gap to blow directly to the upper part of the inner drum 30 along the side wall of the observation window 50 during the clothes drying process. Since the clothes are located in the lower part of the inner drum 30, a large amount of hot air flows out directly from the inner drum 30 without contacting the clothes, resulting in poor heat exchange effect and low drying efficiency.

[0045] In view of this, the present application may consider forming a transition slope on the observation window so that during the drying process, the transition slope can guide the hot air flowing into the flow gap to the lower part of the inner drum, so that more hot air can be blown onto the clothes to be dried, instead of flowing directly out of the inner drum, thereby enhancing the heat exchange capacity and thus improving the drying efficiency.

[0046] Figure 2 This is a partial structural diagram of the washer-dryer combo in the embodiments of this application. Figure 1 , Figure 3 This is an exploded view of a portion of the washer-dryer combo in an embodiment of this application. (Refer to...) Figure 2 and Figure 3 This application provides a washer-dryer combo that can wash, spin-dry, and dry clothes. The washer-dryer combo includes an outer drum 20, an inner drum 30, and a drying device. An air inlet is located at the top of the drum wall at one end of the outer drum 20, and an air outlet is located at the bottom of the inner drum 30. The drying device includes a drying duct 41, a condenser 43, a heating element disposed within the drying duct 41, and a fan 42. Figure 2In the embodiment, the drying air duct 41 is arranged outside the outer cylinder 20 and extends along the axial direction of the outer cylinder 20 from the rear end of the outer cylinder 20 to the cylinder mouth of the outer cylinder 20, and the condenser 43 is arranged outside the outer cylinder 20 along the circumferential direction of the outer cylinder 20, and the air inlet end of the condenser 43 communicates with the inside of the outer cylinder 20, so that the air outlet communicates with the condenser 43.

[0047] The washer-dryer further comprises a ring-shaped window gasket, which is mounted in the cylinder mouth of the outer cylinder 20 and the inner wall of which encloses a laundry loading / unloading opening, which communicates with the cylinder mouth of the inner cylinder 30, so that the laundry can be put into the inner cylinder 30 from the laundry loading / unloading opening.

[0048] Figure 4 Fig. 1 is a schematic view of a structure of an observation window in an embodiment of the present application. Figure 4 The washer-dryer comprises a door, which comprises an observation window 50 capable of rotating relative to the cabinet to open and close the laundry loading / unloading opening. Specifically, the observation window 50 can comprise a ring-shaped outer rim 51, an inner bottom surface 52, and a connecting enclosing wall 53, the ring-shaped outer rim 51 is used to be fixed with the outer frame of the door, the center line of the ring-shaped outer rim 51 and the inner bottom surface 52 are parallel to the horizontal plane, and there is a certain distance between the ring-shaped outer rim 51 and the inner bottom surface 52, and the inner bottom surface 52 is connected with the inner circle of the ring-shaped outer rim 51 through the connecting enclosing wall 53, so that the inner bottom surface 52 can protrude from the ring-shaped outer rim 51. When the observation window 50 closes the laundry loading / unloading opening, the bottom of the observation window 50 can extend into the laundry loading / unloading opening to block the laundry from entering the flow gap between the observation window 50 and the ring-shaped window gasket.

[0049] In the embodiment, the inner bottom surface 52, the connecting enclosing wall 53, and the ring-shaped outer rim 51 together enclose a concave cavity with an opening, and the opening of the concave cavity faces outward of the cabinet of the washer-dryer. That is, the observation window 50 is formed with a concave cavity, so that the bottom of the observation window 50 protrudes into the inner cylinder 30. When the observation window 50 closes the laundry loading / unloading opening, the inner bottom surface 52 is opposite to the cylinder bottom of the inner cylinder 30.

[0050] In the embodiment, the connecting enclosing wall is formed with a transition slope, and the cross section of the connecting enclosing wall along the central axis of the ring-shaped outer rim 51 gradually decreases from the first end close to the ring-shaped outer rim 51 to the second end close to the inner bottom surface 52.

[0051] Optionally, the inner bottom surface 52 can be circular, the center line of the circular inner bottom surface 52 is arranged in line with the central axis of the ring-shaped outer rim 51, and the diameter of the circular inner bottom surface 52 is smaller than the diameter of the inner circle of the ring-shaped outer rim 51. At this time, the observation window 50 is in the shape of a hollow circular truncated cone, and when the observation window 50 closes the laundry loading / unloading opening, the small-diameter end of the hollow circular truncated cone-shaped observation window 50 is closer to the cylinder bottom of the inner cylinder. In this example, the side surface of the hollow circular truncated cone-shaped observation window 50 is the transition slope.

[0052] When the clothes loading and unloading opening is closed in the observation window 50, the transition slope is close to the air inlet. During drying, the hot air introduced from the air inlet into the outer drum 20 flows toward the transition slope and then flows along the transition slope to the lower part of the inner drum.

[0053] Figure 5 A schematic diagram of a washer-dryer combo with an observation window is shown. Figure 5 As shown, the drying process of the washer-dryer combo is as follows: the fan 42 drives air to flow along the drying duct 41. The air flows through the heating tube 44 and is heated to obtain hot air. The hot air flows from the air inlet 21 into the flow gap between the observation window 50 and the annular window gasket. Then, the hot air flows obliquely downward along the transition slope of the observation window 50 to the lower part of the inner drum 30. The hot air comes into contact with the wet clothes and becomes humid hot air. The humid hot air is discharged from the air outlet of the inner drum 30 into the cavity and then flows into the condenser 43. Subsequently, the humid hot air becomes dry and cold air and flows back into the drying duct 41. This cycle repeats continuously.

[0054] In summary, the washer-dryer provided in this embodiment has a flow-guiding function in the transition slope of the observation window 50, which guides the hot air to the lower part of the inner drum 30 where clothes are placed. This allows more hot air to come into contact with the clothes and exchange heat before being discharged from the inner drum 30, reducing heat loss and improving the heat exchange effect, which is beneficial to improving drying efficiency.

[0055] Figure 6 This is a schematic diagram of another viewing window structure in an embodiment of this application. As an alternative embodiment, such as... Figure 6 As shown, the connecting wall includes a connecting ring sidewall 532 and an inclined guide wall 531 extending downwards. The highest point of the inclined guide wall 531 is connected to the outer edge of the ring, and the lowest point of the inclined guide wall 531 is connected to the inner bottom surface. The surface of the inclined guide wall 531 is formed as a transition slope. Both the inclined guide wall 531 and the inner bottom surface are connected to the outer edge of the ring through the connecting ring sidewall 532. It can be seen that in this embodiment, the observation window 50 is an irregular three-dimensional structure.

[0056] The angle between the inclined guide wall 531 and the horizontal plane is not limited, as long as the inclined guide wall 531 can guide the hot air flowing from the air inlet into the flow gap to the lower part of the inner drum 30, so that the hot air can flow along the inclined guide wall 531 into the position of the inner drum 30 for holding clothes.

[0057] Further, the junction between the inclined flow guide wall 531 and the inner bottom surface 52 can be provided with a fillet. In this way, a smooth transition surface is formed between the inclined flow guide wall 531 and the inner bottom surface 52, so as to avoid the junction between the inclined flow guide wall 531 and the inner bottom surface 52 being too steep, especially for a washing and drying integrated machine with a small capacity (for example, a washing and drying integrated machine with a capacity of the inner drum 30 being less than or equal to 5 Kg). By providing the smooth transition surface, the smooth transition surface can also play a flow guiding role, so that the hot air can flow more smoothly to the lower region of the inner drum 30.

[0058] The fillet radius of the junction between the inclined flow guide wall 531 and the inner bottom surface 52 is reasonably set, so that the flow guiding effect of the smooth transition surface can be optimized. Exemplarily, the fillet radius of the junction between the inclined flow guide wall 531 and the inner bottom surface 52 can be 25 mm to 35 mm. Specifically, the above-mentioned fillet radius can be 30 mm.

[0059] The junction between the inclined flow guide wall 531 and the connecting ring side wall 532 and the junction between the inner bottom surface 52 and the connecting ring side wall 532 can also be provided with a fillet. By setting the junction as a fillet, the internal stress at the connection position of each surface can be effectively reduced. Similarly, the junction between the connecting surrounding wall 53 and the annular outer edge 51 can also be provided with a fillet, so as to facilitate the reduction of the internal stress at the connection position of the connecting surrounding wall 53 and the annular outer edge 51.

[0060] Exemplarily, the fillet radius of the junction between the inclined flow guide wall 531 and the connecting ring side wall 532 can be 20 mm to 30 mm, and the fillet radius of the junction between the inner bottom surface 52 and the connecting ring side wall 532 can also be 20 mm to 30 mm. Preferably, the fillet radius of the junction between the connecting ring side wall 532 and the inclined flow guide wall 531 and the inner bottom surface 52 can be set to be the same, for example, the fillet radius of the junction between the connecting ring side wall 532 and the inclined flow guide wall 531 and the inner bottom surface 52 can all be 25 mm. In this way, the fillet radius of the two junctions of the observation window 50 is uniform, and the observation window 50 is more beautiful.

[0061] On the basis of the above-mentioned embodiments, the washing and drying integrated machine can further include a spraying device for spraying water onto the observation window 50. This configuration is mainly applicable to the washing program of the washing and drying integrated machine. During washing, the user often adds detergent, and the detergent will form foam, which will adhere to the observation window 50. The spraying device sprays water onto the observation window 50 to clean the observation window 50, which is beneficial to avoid the foam remaining on the observation window 50 to form dirt, and further beneficial to avoid the dirt on the observation window 50 causing secondary pollution to the clothes.

[0062] The spraying device can specifically include a water supply device, a water inlet pipe and a spraying head 60 connected in sequence. The water supply device supplies water to the spraying head 60 through the water inlet pipe. The spraying head 60 has a water outlet hole 630. When the observation window 50 closes the clothes taking and placing opening, the water outlet hole 630 is located above the inclined flow guide wall 531. In this example, the inclined flow guide wall 531 can guide the flow of water. When the washing and drying integrated machine washes clothes, the water sprayed by the spraying head 60 flows above the inclined flow guide wall 531. The water can flow along the inclined flow guide wall 531 to the inner bottom surface 52 and the connecting ring side wall 532, so that the observation window 50 is washed clean.

[0063] The water supply device can include a water storage tank and a delivery pump. The water inlet of the delivery pump is in communication with the water storage tank, and the water outlet of the delivery pump is in communication with the water inlet pipe to supply water to the spraying head 60. The water storage tank can be arranged at the bottom of the cabinet of the washing and drying integrated machine, so that the water storage tank can be stably supported. The water storage tank can also be arranged near the front panel in the cabinet. The front panel is provided with a maintenance opening which is configured to be opened so that the user can add water to the water storage tank through the maintenance opening. When the water storage tank is near the front panel, the length of the water inlet pipe is also short, which is convenient for arrangement.

[0064] Alternatively, in other possible implementations, the water storage tank can also be replaced by the condenser 43. In this way, the spraying device can use the condensed water separated by the condenser 43 to wash the observation window 50, so that the utilization rate of the condensed water is high. In this embodiment, the water inlet pipe needs to be arranged from the bottom of the outer drum 20 to the drum opening of the outer drum 20.

[0065] In combination with the foregoing description, the junction of the inclined flow guide wall 531 and the inner bottom surface 52 can be provided with a rounded corner. The junction of the inclined flow guide wall 531 and the connecting ring side wall 532 and the junction of the inner bottom surface 52 and the connecting ring side wall 532 can also be provided with a rounded corner. Hereinafter, for the convenience of description, the junction of the inclined flow guide wall 531 and the connecting ring side wall 532 is referred to as the first connecting edge 54, the junction of the inner bottom surface 52 and the connecting ring side wall 532 is referred to as the second connecting edge 55, and the junction of the inclined flow guide wall 531 and the inner bottom surface 52 is referred to as the transition connecting edge 56.

[0066] Specifically, when the first connecting edge 54, the second connecting edge 55 and the transition connecting edge 56 are all provided with a rounded corner structure, the water outlet hole 630 can be aligned with the junction of the inclined flow guide wall 531 and the connecting ring side wall 532, that is, the water outlet hole 630 is aligned with the first connecting edge 54.

[0067] In the embodiment, the working process of the washing and drying integrated machine to flush the observation window 50 is as follows: the water flowing out of the water outlet hole 630 sprays on the first connecting edge 54, the water can flow downward along the first connecting edge 54, and since the first connecting edge 54 is arc-shaped, the water can also flow along the arc-shaped first connecting edge 54 to the connecting ring side wall 532, so that the connecting ring side wall 532 can be flushed clean. At the same time, the water sprayed on the first connecting edge 54 can also slide along the inclined flow guide wall 531 to the transition connecting edge 56, and since the transition connecting edge 56 is arc-shaped, the water can easily flow along the transition connecting edge 56 to the inner bottom surface 52, so that the inclined flow guide wall 531 and the inner bottom surface 52 can be flushed clean.

[0068] Specifically, refer to Figure 7 , Figure 7 FIG. 4 is a fluid simulation diagram of the observation window of the washing and drying integrated machine in the embodiment of the present application, which shows the fluid simulation schematic diagram of the observation window 50 when being sprayed by the spraying device, and the inner drum 30 of the washing and drying integrated machine having the observation window 50 has a capacity of 4 Kg, wherein the dashed line represents the flow path of the water. In the embodiment, the circular radius of the first connecting edge 54 and the second connecting edge 55 is 25 mm, and the circular radius of the transition connecting edge 56 is 30 mm.

[0069] In general, compared with too small curvature at the joint, by setting the first connecting edge 54, the second connecting edge 55 and the transition connecting edge 56 as the rounded corner structure, the curvature of the three connecting edges is increased to avoid the joint being too steep, so that the water flowing through the three connecting edges is subjected to small surface tension effect, and the water is easy to spread on the outer surface of the observation window 50 instead of flowing downward in a stream, so that the connecting surrounding wall 53, the inclined flow guide wall 531 and the inner bottom surface 52 can be flushed, which is beneficial to ensure that the outer surface of the observation window 50 can be flushed clean, and further beneficial to avoid dirt and bacteria breeding on the observation window 50 to cause secondary pollution to the clothes.

[0070] The spraying head 60 will be described in detail below in combination with the accompanying drawings.

[0071] Figure 8 FIG. 5 is a partial structure diagram of the washing and drying integrated machine in the embodiment of the present application Figure 1 . As shown in Figure 8 , the spraying head 60 at least includes a spraying pipe 61 in communication with the water inlet pipe, the spraying pipe 61 is installed on the outer drum 20 and extends into the clothes taking and placing opening, so that the water outlet hole 630 is opposite to the first connecting edge 54. Wherein, the outer drum 20 is provided with a through hole, the annular window gasket is provided with a through hole, the through hole and the through hole are coaxially arranged, and the spraying pipe 61 extends into the clothes taking and placing opening through the through hole and the through hole in sequence. In this way, the spraying head 60 can be stably installed.

[0072] It can be understood that the spray head 60 can be configured such that the water outlet hole 630 can be aligned with any position at the joint of the inclined guide wall 531 and the connecting surrounding wall 53 when the observation window 50 closes the clothes taking and placing opening.

[0073] Figure 9 A schematic diagram of another cooperation between the observation window and the spray head in the embodiment of the present application Figure 1 In one case, as shown in Figure 9 , the axis of the spray pipe 61 can be perpendicular to the horizontal plane, and the water outlet hole is directly opposite the highest point of the inclined guide wall 531. At this time, the observation window 50 is a symmetrical structure, and the symmetry plane of the observation window 50 is perpendicular to the horizontal plane, and the axis of the spray pipe 61 is coplanar with the symmetry plane of the observation window 50. Correspondingly, the center line of the air inlet can be collinear with the axis of the spray pipe 61, and the air inlet is directly opposite the highest point of the inclined guide wall 531, so that the hot air introduced into the outer cylinder directly blows to the inclined guide wall 531.

[0074] Figure 10 A schematic diagram of another cooperation between the observation window and the spray head in the embodiment of the present application Figure 1 In another case, as shown in Figure 10 , the line connecting the highest point of the inclined guide wall 531 to the lowest point of the inclined guide wall 531 forms a straight line Q, the axis of the spray pipe 61 is a straight line P, and the axis of the height direction of the washer-dryer is a straight line Y, and the straight line Q and the straight line P are located on both sides of the straight line Y and are both inclined to the straight line Y. At this time, the inclined guide wall 531 can be regarded as being deflected to the axis of the height direction of the washer-dryer.

[0075] Specifically, as shown in Figure 10 , the first connecting edge 54 includes a first section 540, a second section 542, and an intermediate section 541 connecting the first section 540 and the second section 542, the left side of the second connecting edge 55 is connected to the intermediate section 541 through the first section 540, and the right side of the second connecting edge 55 is connected to the intermediate section 541 through the second section 542. At this time, the water outlet hole 630 can be aligned with the first section 540 or the second section 542.

[0076] Figure 11 A schematic diagram of the structure of the spray head in the embodiment of the present application. Referring to Figure 11 , the spray head 60 can further include a mounting plate 62, a fixed side wall 64, and a water guide plate 63, the mounting plate 62 is perpendicular to the central axis of the spray pipe 61 and is connected to the water outlet end of the spray pipe 61, the water guide plate 63 is located below the mounting plate 62 and has a gap between the two, the water guide plate 63 is connected to the mounting plate 62 through the fixed side wall 64, and the water outlet hole 630 is arranged on the water guide plate 63. When the washer-dryer is working, the water in the spray pipe 61 falls onto the water guide plate 63 through the gap between the mounting plate 62 and the water guide plate 63 from the water outlet end, flows to the water outlet hole 630, and then flows out from the water outlet hole 630 and falls onto the first connecting edge 54.

[0077] In addition, the mounting plate 62, the fixed side wall 64 and the water guide plate 63 can collectively define a water spraying slit, and the water outlet hole 630 can guide water out. Specifically, the water spraying slit can be configured to guide water to the contact position between the observation window 50 and the annular window gasket when the observation window 50 closes the clothes taking and placing opening. In this way, the water sprayed by the spraying device can not only be used to clean the inner surface of the observation window 50, but also be used to clean the flow gap between the observation window 50 and the annular window gasket, so that the foam is not easy to stay in the flow gap, thereby reducing the possibility of the annular window gasket being stained and mildewed due to the attachment of the foam on the annular window gasket, so as to keep the washing and protecting space surrounded by the observation window 50 and the outer drum 20 clean.

[0078] In the illustrated case, the water spraying slit can be aligned with the contact position between the observation window 50 and the annular window gasket. Figure 10 In the illustrated case, the angle between the position aligned by the water spraying slit and the vertex of the middle section 541 of the first connecting edge 54 can be 30°.

[0079] Exemplarily, the shape of the mounting plate 62 is non-limiting. For example, the mounting plate 62 can be in a regular shape such as a triangle, a rectangle, an arc, a circle, etc., or in other irregular shapes. The shape of the water guide plate 63 is similar to that of the mounting plate 62, which will not be described herein again. When the mounting plate 62 and the water guide plate 63 are both in an arc shape, the mounting plate 62, the fixed side wall 64 and the water guide plate 63 collectively surround an arc-shaped water spraying slit, and the arc-shaped water spraying slit can spray water to the contact position between the observation window 50 and the annular window gasket in a concentrated manner to clean the foam between the observation window 50 and the annular window gasket.

[0080] The water guide plate 63 can be parallel to the mounting plate 62, and in this case, the height of the fixed side wall 64 is uniform. As an alternative example, the water guide plate 63 can also be inclined to the mounting plate 62, that is, the water guide plate 63 extends obliquely downward, and in this case, the height of the fixed side wall 64 gradually increases from one end of the water guide plate 63 close to the mounting plate 62 to the other end of the water guide plate 63 away from the mounting plate 62. In this way, the water guide plate 63 can play a flow guiding role, and under the guidance of the water guide plate 63, the water flowing out of the water spraying slit is easy to spray to the contact position between the observation window 50 and the annular window gasket, thereby improving the cleaning effect of the contact position between the observation window 50 and the annular window gasket and reducing the possibility of the annular window gasket being mildewed due to the residual foam.

[0081] The position and size of the water outlet hole 630 are reasonably set, so that part of the water flowing out of the water outlet end of the spraying pipe 61 can flow out of the water outlet hole 630 to clean the outer surface of the observation window 50, and the other part of the water can flow out of the water spraying slit to clean the flow gap. Specifically, as shown in Figure 11As shown, the center line of the water outlet hole 630 can be arranged in line with the center line of the spray pipe 61, that is, the water outlet hole 630 is located directly below the water outlet end of the spray pipe 61. Moreover, the diameter of the water outlet hole 630 is smaller than the inner diameter of the spray pipe 61, so that the water flowing out of the water outlet end of the spray pipe 61 will not all flow out of the water outlet hole 630.

[0082] The size of the water outlet hole 630 is reasonably designed so that the amount of water flowing out of the water outlet hole 630 is less than the amount of water flowing out of the water spray slit. Because the foam in the flow gap is more difficult to be washed away, resulting in the annular window cushion being prone to mold due to residual foam, such an arrangement can enable more water to wash the flow gap, and more effectively clean the observation window 50. For example, the flow rate of the water spray slit can account for 60% of the total flow rate of the shower head 60, and correspondingly, the flow rate of the water outlet hole 630 can account for 40% of the total flow rate of the shower head 60.

[0083] In addition, the upper surface of the mounting plate 62 can further protrude a stop portion, the upper end of the stop portion abutting against the annular window cushion. By arranging the stop portion, when the spray pipe 61 is inserted into the through hole from the clothes taking and placing opening during installation of the shower head 60, and then the spray pipe 61 is caused to pass through the via hole, when the stop portion abuts against the annular window cushion, it indicates that the shower head 60 is installed in place.

[0084] The stop portion can be in a block structure or a columnar structure, which is not limited in the embodiment. Figure 11 In the example shown, the stop portion can also be an annular stop wall 65, which surrounds the spray pipe 61, and the upper surface of the annular stop wall 65 contacts the annular window cushion. Further, the upper surface of the annular stop wall 65 can be arranged as a slope, and the slope completely matches the inner wall of the annular window cushion. Because the inner wall of the annular window cushion is curved, by arranging the upper surface of the annular stop wall 65 as a slope, the upper surface of the annular stop wall 65 easily adapts to the inner wall of the annular window cushion, so as to ensure that the annular stop wall 65 can completely contact the annular window cushion.

[0085] So far, the technical solution of the present application has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after such changes or replacements will all fall within the protection scope of the present application.
