[0048] Embodiment 1

[0049] In order to solve the problem that when washing underwear in an ordinary washing machine, the underwear repeatedly rotates and tumbles in the washing drum, and is twisted, entangled, and dropped, which can easily cause the underwear to deform or the fabric to wear, affecting the wearing experience and shortening the service life of the underwear.

[0050] like Figure 1 and Figure 2 As shown, this embodiment discloses a underwear washing and nursing machine, which includes a housing 1, a drawer, a spray mechanism, a drying mechanism and a support frame 4. The drawer is located in the chamber of the housing 1 in a pull-out manner. The drawer includes a panel 2 and a water tank 3. The water tank 3 is fixed on the panel 2 and is used to hold washing water. The push-pull panel 2 can extend the water tank 3 into the chamber of the housing 1 or pull it out from the chamber of the housing 1. A sealing member 13 is fixed on the top wall of the housing 1. In this embodiment, the sealing member 13 is a sealing strip made of silicone material. When the panel 2 is pushed to close the open end of the housing 1, the sealing strip fits the inner periphery of the water tank 3, which can reduce the possibility of water in the water tank 3 flowing out into the housing 1.

[0051] like Figures 2 to 6 As shown, the support frame 4 is located in the water tank 3, and the underwear 12 is placed on the support frame 4. The support frame 4 is provided with a plurality of water-permeable holes. The spray mechanism is installed at the bottom of the water tank 3. The water sprayed by the spray mechanism can pass through the water-permeable holes and spray to the underwear 12 to clean the underwear 12. An air duct 42 is provided in the support frame 4. A plurality of air outlet holes 41 are provided on the side of the support frame facing the underwear. The air outlet holes 41 are connected to the air duct 42. One side of the support frame 4 passes through the water tank 3 and is fixed on the drawer. The air duct 42 is connected to the drying mechanism. Hot air can be supplied into the water tank 3 through the drying mechanism to dry the underwear 12.

[0052] like Figure 2 , Figure 3 and Figure 5 As shown, the underwear washing and care machine also includes a limiting bracket and a guiding mechanism for guiding the limiting bracket. The limiting bracket includes a frame 61 and a pair of limiting holes 62 provided on the frame 61. The cups of the underwear 12 are inserted into the limiting holes 62 one by one, so that the frame 61 can limit the underwear 12. The guiding mechanism includes a guide rod 81, a guide sleeve 82 and a stopper 83. The number of the guide rod 81, the guide sleeve 82 and the stopper 83 can be one or more. In this embodiment, the number of the guide rod 81, the guide sleeve 82 and the stopper 83 is set to two, so that the frame 61 can move more stably. In addition, the guiding mechanism and the limiting bracket can be set to multiple, so that the underwear washing and care machine can clean multiple underwear 12 at the same time, thereby improving the cleaning efficiency.

[0053] like Figure 2 , Figure 3 and Figure 5 As shown, the two guide rods 81 are fixed on the support frame 4, the two guide sleeves 82 are slidably sleeved on the guide rods 81 in a one-to-one manner and fixedly connected to the frame 61, and the two stoppers 83 are fixed in a one-to-one manner on the end of the limiting bracket away from the support frame 4. The stoppers 83 can reduce the possibility of the guide sleeves 82 escaping from the guide rods 81.

[0054] When cleaning the underwear 12, first place the underwear 12 on the support frame 4, then move the frame 61 so that the cup of the underwear 12 is located in the limiting hole 62, push the panel 2 to extend the water tank 3 into the shell 1, and then start the spray mechanism. The water sprayed by the spray mechanism can be sprayed on the underwear 12 to clean the underwear 12, and at the same time, the frame 61 can be driven to move back and forth along the guide rod 81, so that the frame 61 can beat the underwear 12 to clean the underwear 12. In addition, during the movement of the frame 61, the cup of the underwear 12 is always located within the sleeve range of the limiting hole 62, which can reduce the possibility of a large displacement of the underwear 12 during the washing process, thereby reducing the twisting and entanglement of the underwear 12, and further reducing the possibility of deformation of the underwear 12.

[0055] Furthermore, a plurality of flexible strips 7 are fixed on the skeleton 61. The flexible strips 7 can be made of flexible materials such as rubber and silicone. During the movement of the skeleton 61, the flexible strips 7 move synchronously with the skeleton 61 and beat the underwear 12, thereby further improving the cleaning effect of the underwear 12. In addition, using flexible materials to beat the underwear 12 can reduce the wear on the underwear 12 and extend the service life of the underwear 12.

[0056] like Figure 2 As shown, the spray mechanism includes a circulation pump 53, a circulation pipe 54, a water inlet pipe 52 and a spray arm 51. The circulation pump 53 is located in the housing 1 and is installed on the bottom wall of the water tank 3. One end of the circulation pipe 54 is connected to the water tank 3, and the other end of the circulation pipe 54 is connected to the water inlet of the circulation pump 53. The water inlet pipe 52 is connected to the water outlet of the circulation pump 53, and one end of the water inlet pipe 52 away from the circulation pump 53 extends into the water tank 3. The spray arm 51 is located below the support frame 4 and is rotatably connected to the water inlet pipe 52. The spray arm 51 is provided with a plurality of spray holes, and the openings of the spray holes face different directions. The washing water in the water tank 3 can be supplied to the spray arm 51 through the circulation pump 53, and then sprayed out through the spray holes. When spraying water, the spray holes can make the spray arm 51 rotate around its own center position, and the water flow is rotated and sprayed onto the underwear 12, so as to spray and wash the underwear 12.

[0057] The spray arm 51 rotates during the water spraying process, which can increase the spraying area of ​​the water flow on the underwear 12 and improve the uniformity of the spraying, thereby improving the cleaning effect of the underwear 12. In addition, after the water flow is sprayed out of the spray hole, it will stir the washing water in the water tank 3, so that the washing water can drive the frame 61 to reciprocate along the guide rod 81. During the movement of the frame 61, the frame 61 itself and the flexible strip 7 will beat the underwear 12, making it easier to fall off the stains on the underwear 12, thereby further improving the cleaning effect of the underwear 12.

[0058] By cooperating with the flow of washing water and the guide mechanism, the skeleton 61 can be driven to move back and forth to beat and limit the underwear 12. There is no need to add additional power equipment to drive the skeleton 61, which can save power consumption of the underwear washing and care machine.

[0059] like Figure 2 and Figure 6 As shown, after the underwear 12 is washed, the water in the water tank 3 is drained, and then the drying mechanism is started to dry the underwear 12. Since the underwear washing and nursing machine is small in size, the user can manually pour out the water in the water tank 3, and can also manually fill the water into the water tank 3. Automatic water filling and automatic drainage can also be adopted. A drain pipe (not shown in the figure) is connected to the water tank 3, and the drain pipe passes through the panel 2 and extends to the outside. A drain valve is installed on the drain pipe. When the drain valve is opened, the washing water in the water tank 3 can be emptied through the drain pipe. The drain valve is connected to the control system of the underwear washing and nursing machine to control the automatic drainage of the water tank 3. A water injection pipe (not shown in the figure) is connected to the top wall of the housing 1, and a water injection valve is installed on the water injection pipe. The water pipe is connected to the external water supply system. When the water injection valve is opened, water can be automatically injected into the water tank 3. The water injection valve is connected to the control system of the underwear washing and nursing machine, and the water injection valve is controlled to be closed during the washing and drying process of the underwear 12, and opened when water needs to be injected into the water tank 3.

[0060] like Figure 2 and Figure 6 As shown, the drying mechanism includes a fan 91, a heating assembly 92 and an air inlet pipe 93. An exhaust port 101 is provided on the top wall of the housing 1, which allows gas to flow between the water tank 3 and the external environment. An air inlet 102 is provided on the side wall of the housing 1, which allows gas to flow between the housing 1 and the external environment. The fan 91 is installed on the housing 1, the air outlet of the fan 91 is connected to the air inlet pipe 93, the air inlet pipe 93 is connected to the air duct 42, and the heating assembly 92 is installed in the air inlet pipe 93. The heating assembly 92 is a heating device commonly used in the field of washing machine drying, and the specific structure is not repeated here.

[0061] After the underwear 12 is washed, the fan 91 is started to suck the outside air into the air inlet 93 through the air inlet 102, and then the air is sent into the air duct 42 after being heated by the heating component 92. The hot air is ejected through the air outlet 41 to dry the underwear 12, and the hot and humid air in the water tank 3 is discharged from the water tank 3 through the exhaust port 101. After the underwear 12 is washed, the underwear 12 can be firstly squeezed to dehydrate, and then the underwear 12 is placed on the support frame 4 and then dried, which can further improve the drying speed.

[0062] like Figure 2 and Figure 6 As shown, further, the height of the air inlet end of the air inlet pipe 93 is higher than the height of the support frame 4, which can reduce the possibility of water in the water tank 3 splashing into the air inlet pipe 93 and causing water to enter the heating component 92 and the fan 91.

[0063] In addition, a plurality of first baffles 10 are fixed obliquely on one side of the inner wall of the air inlet pipe 93, and a plurality of second baffles 11 are fixed obliquely on the other side of the inner wall of the air inlet pipe 93. The first baffles 10 and the second baffles 11 are both inclined in the direction of the hot air flow. The first baffles 10 and the second baffles 11 are arranged alternately, and the ends of the first baffles 10 and the second baffles 11 away from the air inlet pipe 93 are arranged beyond the central axis of the air inlet pipe 93, forming a labyrinth wind path. This can reduce the resistance of the first baffles 10 and the second baffles 11 to the hot air, and can also block the splashing of water flow, further reducing the possibility of water in the water tank 3 spraying onto the fan 91 and the heating assembly 92, so that the fan 91 and the heating assembly 92 can operate stably.

[0064] As another preferred embodiment, a one-way valve may be installed on the air inlet pipe 93 so that hot air can flow into the air duct 42 and water in the air duct 42 cannot flow back into the fan 91 and the heating assembly 92 .

[0065] like Figure 2 and Figure 6 As shown, further, the underwear washing and care machine also includes a sealing mechanism, a mounting groove is provided on the top wall of the housing 1, and the sealing mechanism is installed in the mounting groove to open or close the exhaust port 101. The sealing mechanism includes a driving member 141 and a valve plate 142, and the driving member 141 can drive the valve plate 142 to move to the exhaust port 101 to close the exhaust port 101; or drive the valve plate 142 to move out of the exhaust port 101 to open the exhaust port 101. In this embodiment, the driving member 141 adopts an electric push rod, which is fixed on the inner wall of the mounting groove, and the output end of the electric push rod is fixedly connected to the valve plate 142.

[0066] When washing the underwear 12, the electric push rod drives the valve plate 142 to close the exhaust port 101 to reduce the possibility of water in the water tank 3 being sprayed out of the housing 1 through the exhaust port 101. When drying the underwear 12, the electric push rod drives the valve plate 142 to open the exhaust port 101 so that the hot and humid air in the water tank 3 can be discharged from the water tank 3 in time, thereby accelerating the drying speed of the underwear 12.

When washing the underwear 12, the underwear 12 is placed on the support frame 4, the skeleton 61 is moved so that the cup of the underwear 12 is located in the limiting hole 62, detergent is injected into the water tank 3, and then the panel 2 is pushed to extend the water tank 3 into the chamber of the housing 1, and the underwear washing and nursing machine is started.

[0069] The control method of the underwear washing and care machine comprises the following steps:

[0070] S1, after the underwear 12 is placed on the support frame 4 and detergent is added to the water tank 3, water is injected into the water tank 3 to a set water level;
