Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a nozzle body and clothing processing equipment. Background Art

[0002] Taking washing machines as an example, some washing machines are equipped with dual water inlet nozzle bodies. By setting water valves at the two water inlets of the nozzle body, and connecting the two water valves to the cold water pipe and hot water pipe respectively, the purpose of supplying cold water or hot water to the washing chamber according to washing needs is achieved.

[0003] However, the existing dual-inlet sprinkler head has the problem of water leakage between the cold water valve and the hot water valve. If the user connects both water valves to the water pipe, the problem will not be revealed. If the user only connects the cold water pipe and not the hot water pipe, the hot water valve will leak during use, causing floor corrosion, affecting user experience, and in serious cases causing safety accidents. Utility Model Content

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present invention provides a nozzle body and a clothing processing device.

[0039] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0041] Reference Figures 1 to 10 As shown, some embodiments of the present invention provide a nozzle body, which can be used in clothing processing equipment, such as a washing machine. Of course, the nozzle body can also be used in other washing equipment, such as a dishwasher.

[0042] Reference Figures 3 to 8 As shown, some embodiments of the present invention provide a nozzle body, which includes a nozzle body 1 and a stopper 2 .

[0043] Among them, the nozzle body 1 has a first water inlet 11, a second water inlet 12, a water outlet 13, and a first flow channel 14 connecting the first water inlet 11 and the water outlet 13, and a second flow channel 15 connecting the second water inlet 12 and the water outlet 13; that is, the nozzle body 1 has a first water inlet 11, a second water inlet 12 and a water outlet 13, the first water inlet 11 is connected to the water outlet 13 through the first flow channel 14, and the second water inlet 12 is connected to the water outlet 13 through the second flow channel 15, that is, the first water inlet 11 and the second water inlet 12 can share the same water outlet 13.

[0044] In a specific implementation, the nozzle body can be installed on a clothing processing device, the first water inlet 11 can be connected to a cold water pipe, that is, the first water inlet 11 can pass cold water, the second water inlet 12 can be connected to a hot water pipe, that is, the second water inlet 12 can pass hot water, and the water outlet 13 can be connected to the clothing processing chamber of the clothing processing device, so as to achieve the purpose of supplying cold water or hot water to the clothing processing chamber according to washing needs by controlling whether water is entering the first water inlet 11 and the second water inlet 12.

[0045] It should be noted that, in a specific implementation, a first water valve (also known as a cold water valve) is typically installed at the first water inlet 11, and a second water valve (also known as a hot water valve) is typically installed at the second water inlet 12. During specific use, the user can connect the first water valve to the cold water pipe and the second water valve to the hot water pipe, that is, both the first and second water valves are connected to the water pipes. By opening the first water valve and closing the second water valve, cold water is supplied to the clothing treatment chamber. By opening the second water valve and closing the first water valve, hot water is supplied to the clothing treatment chamber.

[0046] However, in actual use, there is often a situation where the user only connects the cold water pipe but not the hot water pipe, that is, only connects the first water valve to the cold water pipe but does not connect the second water valve to the hot water pipe. In this case, when the first water inlet 11 is connected to water (that is, cold water is connected), refer to Figure 3 In the water flow direction indicated by the middle arrow, water will flow through the first flow channel 14 to the water outlet 13. Since the second water inlet 12 is connected to the water outlet 13 through the second flow channel 15, part of the water flowing to the water outlet 13 will flow back along the second flow channel 15 to the second water inlet 12, causing water leakage at the second water valve, causing corrosion to the user's home floor, affecting user experience, and may even cause safety accidents in severe cases.

[0047] Based on this, the nozzle body provided in some embodiments of the present invention is provided with a stopper 2 at the second water inlet 12, and the stopper 2 is configured to block the second water inlet 12 under the action of its own gravity and / or the water pressure of the first water inlet 11, and to open the second water inlet 12 under the action of the water pressure of the second water inlet 12.

[0048] That is to say, in a specific implementation, the stopper 2 can be set to block the second water inlet 12 under the action of its own gravity, or the stopper 2 can be set to block the second water inlet 12 under the action of the water pressure of the first water inlet 11, or the stopper 2 can be set to block the second water inlet 12 under the action of its own gravity and the water pressure of the first water inlet 11.

[0049] Specifically, when water (i.e., cold water) is passed through the first water inlet 11, Figures 3 to 5 As shown, the stopper 2 can block the second water inlet 12 under the action of its own gravity and / or the water pressure of the first water inlet 11, so as to prevent the water from flowing back along the second flow channel 15 and the second water inlet 12 when the first water inlet 11 is flowing, thereby avoiding the problem of water leakage at the second water inlet 12; when the second water inlet 12 is flowing with water (that is, hot water), Figures 6 to 8 As shown, the stopper 2 can be pushed to move and open the second water inlet 12 under the action of the water pressure of the water inlet 12, thereby achieving the purpose of normal water inlet through the second water inlet 12.

[0050] With such arrangement, even if the user only connects the cold water pipe but not the hot water pipe, that is, only connects the first water inlet 11 to the cold water pipe but the second water inlet 12 is not connected to the hot water pipe, when water flows through the first water inlet 11, even if part of the water flows back to the second water inlet 12, due to the blocking effect of the stopper 2, the water will not leak out through the second water inlet 12, thereby avoiding corrosion of the floor and improving the user experience; and when the user connects both the cold water pipe and the hot water pipe at the same time, the setting of the stopper 2 does not affect the normal water inlet of the second water inlet 12, and when water flows through the first water inlet 11, it can prevent cold water from jumping to the hot water, thereby solving the problem of water jumping between cold water and hot water.

[0051] The nozzle body provided by the above-mentioned embodiment of the present disclosure can ensure that the first water inlet 11 and the second water inlet 12 share a water outlet 13, that is, the cold and hot water share a water outlet 13, and avoid the problem of water leakage at the second water inlet 12 when only the first water inlet 11 is connected to the cold water pipe and the second water inlet 12 is not connected to the hot water pipe.

[0052] It should be noted that, in actual use, users usually connect a cold water pipe. There are two situations in which users connect both the cold water pipe and the hot water pipe, or only connect the cold water pipe without the hot water pipe. That is, the first water inlet 11 is usually connected to the cold water pipe. Therefore, when water flows through the second water inlet 12, even if water flows back to the first water inlet 11, there will be no problem of water leakage at the first water inlet 11. Therefore, the nozzle body provided in the embodiment of the present disclosure can be provided with a stopper 2 only at the second water inlet 12 to achieve the purpose of preventing water leakage when the nozzle body is in use.

[0053] Of course, in the specific implementation, it is not limited to setting the stopper 2 only at the second water inlet 12. The stopper 2 can also be set at the first water inlet 11 as needed, so that when water flows through the second water inlet 12, the stopper 2 is used to block the first water inlet 11 to prevent water from flowing back through the first flow channel 14 and the first water inlet 11, thereby achieving the effect of avoiding the mutual leakage of cold water and hot water.

[0054] Furthermore, the nozzle body provided by the embodiment of the present invention can be used on different models of clothing processing equipment. In other words, the same nozzle body can be installed on different models, improving the versatility of the nozzle body. For example, if some models only have a cold water inlet, using the nozzle body provided by the embodiment of the present invention eliminates the need to worry about water leakage at the hot water inlet of such models. In other words, the nozzle body provided by the embodiment of the present invention is applicable not only to dual-inlet models but also to single-inlet models.

[0055] In some embodiments, reference Figure 3As shown, the second water inlet 12 has a water inlet port and a water outlet port that are connected to each other. The water inlet port is used to connect to a water pipe, and the water outlet port is connected to the second flow channel 15. The stopper 2 is provided at the water outlet port.

[0056] In the specific implementation, refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, the second water inlet 12 can be set as a channel-shaped water inlet structure, with the end port away from the second flow channel 15 forming a water inlet port, and the end port close to the second flow channel 15 forming a water outlet port. The water flows into the second flow channel 15 through the water inlet port and the water outlet port in sequence, and the stopper 2 is set at the water outlet port. In this way, when water flows through the second water inlet 12, the water pressure of the second water inlet 12 will push the stopper 2 to move in the direction of water flow to open the second water inlet 12 and achieve the purpose of normal water intake of the second water inlet 12; when water flows through the first water inlet 11, when the water flows back along the second flow channel 15 to the second water inlet 12, the water pressure of the first water inlet 11 will push the stopper 2 to move in the reverse direction and block the second water inlet 12.

[0057] It should be noted that the water pressure direction of the water flow entering from the second water inlet 12 on the stopper 2 is opposite to the water pressure direction of the water flow entering from the first water inlet 11 on the stopper 2, thereby achieving the purpose of the stopper 2 blocking or opening the second water inlet 12.

[0058] In some embodiments, reference Figure 3 As shown, a receiving groove 16 is formed between the second water inlet 12 and the second flow channel 15 . The second water inlet 12 is connected to the groove wall of the receiving groove 16 and communicates with the second flow channel 15 through the receiving groove 16 .

[0059] In the specific implementation, refer to Figure 2 and Figure 3 As shown, the bottom wall of the receiving groove 16 can be set lower than the bottom wall of the second flow channel 15, the top end surface of the groove wall on one side of the receiving groove 16 is flush with the bottom wall of the second flow channel 15, and the top end surfaces of the other side groove walls of the receiving groove 16 are higher than the bottom wall of the second flow channel 15. With this arrangement, the water entering from the second water inlet 12 can be first stored in the receiving groove 16, and then overflow into the second flow channel 15 when the water level in the receiving groove 16 reaches a certain level, which can improve the stability of the water flow.

[0060] When implementing it, refer to Figures 3 to 8As shown, the stopper 2 is disposed in the receiving groove 16 and is capable of moving within the receiving groove 16 to block or open the second water inlet 12. This arrangement provides space for the stopper 2 to move through the receiving groove 16, thereby facilitating the blocking or opening of the second water inlet 12 by the movement of the stopper 2. Furthermore, the stopper 2 can be disposed by utilizing the existing receiving groove structure of the nozzle body, which minimizes structural changes to the nozzle body and is easier to implement.

[0061] In a specific implementation, the stopper 2 can be a rolling sphere, so that the second water inlet 12 can be blocked or opened by the sphere rolling in the receiving groove 16. Of course, the stopper 2 can be a stopper plate, which can be hinged at the second water inlet 12 so that the second water inlet 12 can be blocked or opened by the rotation of the stopper plate. Of course, the stopper 2 can also be other structures that can block or open the second water inlet 12 under the combined action of its own gravity and water pressure.

[0062] In some embodiments, reference Figures 3 to 8 As shown, a guide track 17 is provided on the bottom wall of the accommodating groove 16 , and the guide track 17 at least includes an inclined track section 171 that gradually tilts upward along the water inlet direction of the second water inlet 12 .

[0063] In a specific implementation, the stopper 2 can be placed on the guide rail 17 so that the stopper 2 can move along the inclined rail section 171 of the guide rail 17, and since the inclined rail section 171 gradually tilts upward along the water inlet direction of the second water inlet 12, the stopper 2 can move downward (or has a tendency to move downward) along the inclined rail section 171 under the action of its own gravity, so that the stopper 2 can move to the second water inlet 12 and block the second water inlet 12.

[0064] It should be noted that, in a specific implementation, if the self-gravity of the stopper 2 cannot cause the stopper 2 to move downward along the inclined track section 171, then when water flows through the first water inlet 11, when the water flows back to the second water inlet 12, the water pressure of the backflowing water can be combined with the self-gravity of the stopper to make the stopper 2 move downward along the inclined track section 171 and block the second water inlet 12, thereby also achieving the purpose of preventing water leakage.

[0065] In some embodiments, the stopper 2 is a sphere, which is disposed on the guide track 17. Specifically, the sphere is rollably disposed on the guide track 17. By providing the guide track 17 with an inclined track section 171, when the sphere is on the inclined track section 171, the sphere can roll downward under its own weight and abut against the second water inlet 12 to block the second water inlet 12.

[0066] In a specific implementation, when the second water inlet 12 is not flowing with water, the ball can move to the lower end of the inclined track section 171 of the guide track 17 under its own gravity and block the second water inlet 12. When the first water inlet 11 is flowing with water (i.e., cold water), refer to Figure 3 In the direction of water flow indicated by the middle arrow, water will flow along the first flow channel 14 to the water outlet 13. Part of the water flowing to the water outlet 13 will flow back along the second flow channel 15 to the second water inlet 12. At this time, the water pressure of the backflow will exert a force on the sphere to block the second water inlet 12. Therefore, under the action of the sphere's own gravity and the water pressure of the first water inlet 11, the sphere will tightly block the second water inlet 12, so that the water entering from the first water inlet 11 and flowing back to the second water inlet 12 cannot pass through here, thereby playing a role in preventing backflow. When the second water inlet 12 is flowing with water (i.e., hot water), refer to Figure 6 In the water flow direction shown, under the action of the water pressure of the second water inlet 12, the ball will be pushed away, causing the ball to roll along the guide track 17, so that the second water inlet 12 is opened, and water can enter the nozzle body normally through the second water inlet 12 and flow along the second flow channel 15 to the water outlet 13.

[0067] In some embodiments, reference Figure 5 and Figure 8 As shown, the guide track 17 also includes a horizontal track segment 172, which is connected to the rear end of the inclined track segment 171 along the direction of water inlet 12. In other words, the horizontal track segment 172 is connected to the end of the inclined track segment 171 closest to the second water inlet 12. The provision of the horizontal track segment 172 ensures that when water enters the second water inlet 12, a smaller opening pressure is applied. In other words, a smaller water pressure force is required to push the ball open and open the second water inlet 12.

[0068] It should be noted that the horizontal track section 172 is not necessary. If the water pressure of the second water inlet 12 is relatively high, the guide track 17 can be set to be completely inclined.

[0069] In some embodiments, reference Figure 5 and Figure 8 As shown, a chamfer 121 is provided at the end of the second water inlet 12 facing the sphere, and the sphere abuts against the chamfer 121 to block the second water inlet 12 .

[0070] In practice, chamfer 121 can be rounded or right-angled. Specifically, chamfer 121 is positioned at the end of second water inlet 12 facing the sphere. Along the direction of water inlet 12, chamfer 121 gradually slopes away from the central axis of second water inlet 12, i.e., gradually expands outward. This arrangement increases the contact area between the end of second water inlet 12 and the sphere, ensuring a tight seal when the sphere blocks the second water inlet 12.

[0071] In some embodiments, the sphere is a rubber sphere or is coated with a rubber layer. This arrangement can ensure the sealing performance of the sphere when blocking the second water inlet 12.

[0072] In a specific implementation, the diameter of the sphere needs to be larger than the diameter of the second water inlet 12, and the density of the sphere needs to be larger than the density of water. There is no specific limitation on the specific size and material of the sphere, and they can be reasonably set according to actual needs.

[0073] Of course, in a specific implementation, the stopper 2 is not limited to being a sphere, and the stopper 2 may also be a structure such as a stopper block, and the stopper 2 is slidably disposed on the guide track 17. The friction between the stopper 2 and the guide track 17 is overcome by the weight of the stopper 2 (or by the water pressure of the water entering from the first water inlet 11 and flowing back to the second water inlet 12), so that the stopper 2 moves downward along the inclined track section 171 of the guide track 17 to block the second water inlet 12.

[0074] It should be noted that the guide track 17 may also not be provided with the inclined track section 171, that is, the guide track 17 only includes the horizontal track section 172, and the stopper 2 is placed on the horizontal track section 172. Relying on the water pressure entering from the first water inlet 11 and flowing back to the second water inlet 12, the stopper 2 is pushed along the horizontal track section 172 to block the second water inlet 12.

[0075] In other embodiments, the stop member 2 is a stop plate having a first end and a second end relative to each other. The first end of the stop plate is located above the second water inlet 12 and is hinged to the nozzle body 1, and the second end of the stop plate is a free end.

[0076] In a specific implementation, when water does not flow through the second water inlet 12, the stop plate can be in a vertical state under the action of its own weight and block the second water inlet 12. When water flows through the first water inlet 11 (i.e., cold water), water will flow along the first flow channel 14 to the water outlet 13. Part of the water flowing to the water outlet 13 will flow back along the second flow channel 15 to the second water inlet 12. At this time, the backflow water pressure will exert a force on the stop plate to block the second water inlet 12. Therefore, under the action of the stop plate's own weight and the water pressure of the first water inlet 11, the stop plate will tightly block the second water inlet 12, so that water entering from the first water inlet 11 and flowing back to the second water inlet 12 cannot pass through here, thereby playing a backflow prevention role. When water flows through the second water inlet 12 (i.e., hot water), the stop plate will be pushed open under the action of the water pressure of the second water inlet 12, causing the stop plate to rotate relative to the nozzle body 1, so that the second water inlet 12 is opened, and water can enter the nozzle body normally through the second water inlet 12.

[0077] In some embodiments, a sealing ring is provided on the side surface of the stop plate facing the second water inlet 12, and the diameter of the sealing ring is larger than the diameter of the second water inlet 12. When the stop plate blocks the second water inlet 12, the sealing ring abuts against the end face located around the second water inlet 12, so that the stop plate can better block the second water inlet 12.

[0078] In some embodiments, along the flow direction of water flowing from the second water inlet 12 to the water outlet 13, the second flow channel 15 is formed as an inclined flow channel that gradually slopes downward. Figure 6 As shown, the second flow channel 15 is along Figure 6 The arrows shown are gradually inclined downward. With this arrangement, when water flows through the second water inlet 12, water flowing from the second water inlet 12 to the second flow channel 15 can flow more easily along the inclined second flow channel 15 to the water outlet 13. When water flows through the first water inlet 11, if some water flows back along the second flow channel 15 toward the second water inlet 12, the water can flow along the inclined second flow channel 15 under its own gravity and flow back to the water outlet 13, thereby better preventing water leakage from the second water inlet 12.

[0079] In some embodiments, the nozzle body includes two stoppers 2, namely a first stopper and a second stopper. The first stopper is arranged at the second water inlet 12, and the first stopper is configured to block the second water inlet 12 under the action of its own gravity and / or the water pressure of the water inlet of the first water inlet 11, and to open the second water inlet 12 under the action of the water pressure of the water inlet of the second water inlet 12; the second stopper is arranged at the first water inlet 11, and is configured to block the first water inlet 11 under the action of its own gravity and / or the water pressure of the water inlet of the first water inlet 11, and to move relative to the nozzle body 1 and open the first water inlet 11 under the action of the water pressure of the water inlet of the first water inlet 11.

[0080] With such a configuration, when water flows through the first water inlet 11, the second water inlet 12 is blocked by the first stopper to prevent water from flowing back to the second water inlet 12 and causing water leakage; when water flows through the second water inlet 12, the first water inlet 11 is blocked by the second stopper to prevent water from flowing back to the first water inlet 11 and causing water leakage, thereby achieving the effect of preventing cold water and hot water from flowing into each other.
