Description

Technical Field

[0001] This technical solution relates to the field of pressurized garment steamer technology, specifically a high-pressure steam delivery system. Background Technology

[0002] A pressurized garment steamer is a type of environmentally friendly cleaning appliance. It consists of a main unit, steam pipes, and steam nozzles. The main unit has a steam generator and is placed on the ground or countertop. High-temperature steam is drawn out through the steam pipes, delivered to the steam nozzles, and sprayed out from the nozzles to clean and iron clothes.

[0003] In existing pressurized garment steamers, the high-temperature steam releases heat rapidly when it comes into contact with the inner wall of the lower-temperature nozzle, resulting in condensation. To address this, an independent condensate return pipe is designed to connect the steam nozzle and the main unit. For example, Chinese patent CN202322608115.6 discloses an extended handle ironing head and garment steamer, which can quickly drain the condensate through drainage holes and collect it back into the main body of the garment steamer for recycling through a drainage pipe.

[0004] However, it still has some shortcomings. The inner diameter of the return water pipe (i.e., the drain pipe) is small. It can only push the water in the return water pipe back when the machine is working and the internal pressure of the steam nozzle increases. When the machine is not in use, the condensate will remain in the return water pipe. If it is not used for a long time, the condensate accumulated in the return water pipe is very easy to breed bacteria, which will lead to the inside becoming dirty and even causing blockage, affecting normal use. Utility Model Content

[0005] The purpose of this technical solution is to provide a high-pressure steam conveying system. By setting a steam conduit inside the conveying pipe, steam flows into the conveying pipe through the steam channel of the steam conduit and then into the steam nozzle. Meanwhile, condensate flows into the return water outlet through the return water channel and is discharged. This improves the existing problem that condensate drainage relies on pressure discharge, which leads to poor drainage and easy retention of condensate.

[0006] The purpose of this technical solution is achieved as follows:

[0007] A high-pressure steam delivery system for installation on a pressurized garment steamer includes:

[0008] The conveying pipe has a return water port at its lower end, and the two ends of the conveying pipe are respectively used to connect the steam nozzle of the pressurized garment steamer to the main unit.

[0009] A steam conduit is installed inside the delivery pipe, and the lower end of the steam conduit is used to connect to the steam outlet of the main unit of the pressurized garment steamer.

[0010] The steam conduit has a steam channel that connects the inside of the delivery pipe to the outside; a return water channel is formed between the outer wall of the steam conduit and the inner wall of the delivery pipe, and the lower end of the return water channel is connected to the return water inlet.

[0011] Preferably, the upper side wall of the steam conduit is provided with an air outlet, which connects the steam conduit to the delivery pipe.

[0012] Preferably, the upper end of the steam conduit is provided with a water-blocking component, and the side end of the water-blocking component is provided with a through hole, the through hole connecting the steam conduit and the delivery pipe.

[0013] Preferably, the upper end of the steam conduit is located in the middle or upper half of the delivery pipe.

[0014] Preferably, the return water inlet is provided with a return water pipe, which connects the return water channel and the main unit of the pressurized garment steamer.

[0015] Preferably, a connecting joint is installed at the lower end of the conveying pipe. The connecting joint is provided with an air inlet and a water return connector. The air inlet is connected to the lower end of the steam conduit, and the water return connector is connected to the water return pipe.

[0016] Preferably, the lower end of the conveying pipe is provided with a connecting seat, the connecting seat is provided with an installation hole and the return water port, and the steam conduit extends out of the lower end of the conveying pipe through the installation hole.

[0017] Preferably, the connector has a water outlet joint, the water outlet joint has the return water port, and the water outlet joint is used to connect to the return water pipe.

[0018] Preferably, the upper end of the connector has a connecting part and a limiting part, the connecting part is inserted into the conveying pipe, and the limiting part abuts against the lower end of the conveying pipe.

[0019] Preferably, a plurality of protruding rings are provided on the outer side of the connecting part, and the protruding rings have a guide surface on the side away from the limiting part, the guide surface being used to guide the connecting part into the delivery pipe.

[0020] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0021] 1. This technical solution involves installing a steam conduit inside the delivery pipe. Steam enters the delivery pipe through the steam channel of the steam conduit, and then enters the steam nozzle for spraying. Meanwhile, the condensate naturally converges to the return port and is discharged due to its own gravity. This eliminates the need to rely on the pressure generated during machine operation to drive the discharge of condensate, improving the convenience and thoroughness of condensate discharge, avoiding blockage problems caused by water accumulation, optimizing the user experience, and extending the service life of the machine.

[0022] 2. This technical solution has an outlet on the upper side wall of the steam conduit. Steam enters the conveying pipe through the outlet. The outlet on the side wall of the steam conduit can prevent condensate from falling into the steam conduit from the upper end, ensuring that the condensate is discharged smoothly along the predetermined path. At the same time, it maintains the stability of steam conveying inside the steam conduit, making the steam output efficient and reliable. Attached Figure Description

[0036] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Combination Figures 1-4 A high-pressure steam delivery system, for installation on a pressurized garment steamer, includes: a delivery pipe 1 and a steam conduit 2; the lower end of the delivery pipe 1 has a return water inlet 31, and both ends of the delivery pipe 1 are respectively used to connect the steam nozzle 6 of the pressurized garment steamer to the main unit, that is, the upper end of the delivery pipe 1 is connected to and communicates with the steam nozzle 6 of the pressurized garment steamer, and the lower end of the delivery pipe 1 is connected to the main unit of the pressurized garment steamer, and the end of the delivery pipe 1 near the main unit has a return water inlet 31, which is used to discharge condensate from the delivery pipe 1 and the steam nozzle 6 into the delivery pipe 1; the steam conduit 2 is installed inside the delivery pipe 1, and the steam conduit 2... The lower end extends into the conveying pipe 1. The lower end of the steam conduit 2 is used to connect to the steam outlet on the steam generator of the pressurized garment steamer. The steam generator delivers steam into the steam conduit 2. The steam conduit 2 has a steam channel 21, which connects the inside of the conveying pipe 1 to the outside. The steam generator transports steam from the steam channel 21 into the conveying pipe 1, and then from the conveying pipe 1 to the steam nozzle 6. A return water channel 11 is formed between the outer wall of the steam conduit 2 and the inner wall of the conveying pipe 1. The lower end of the return water channel 11 is connected to the return water port 31, and the upper end of the return water channel 11 is connected to the steam nozzle 6.

[0039] Condensate flows into return water inlet 31 through return water channel 11 under its own gravity, and then exits through return water inlet 31 into delivery pipe 1. Finally, it is discharged into the water collection area of ​​the main unit or into the water tank, or discharged to the outside. There is no need for secondary heating by steam nozzle 6 to atomize and discharge condensate, nor is it necessary to rely on the pressure generated during machine operation to drive the discharge of condensate. There is no accumulation of condensate in the pipe after the machine stops working, which improves the convenience and thoroughness of condensate discharge, avoids blockage caused by water accumulation, optimizes the user experience, and extends the service life of the machine.

[0040] This technical solution eliminates the need for an additional, larger-diameter pipe inside the conveying pipe 1 to connect the steam nozzle 6 and the main unit's water tank for condensate return. This also eliminates the need to increase the pipe diameter to ensure condensate return, avoiding the increase in the diameter and volume of the conveying pipe 1 due to the additional pipe. It reduces assembly and production time caused by the additional pipe, and improves production efficiency and ease of use of the conveying pipe 1.

[0041] The inner diameter of the conveying pipe 1 is larger than the outer diameter of the steam pipe 2, and the inner diameter of the return water port 31 is larger than the inner diameter of the steam pipe 2. The width of the return water channel 11 is larger than the width of the steam channel 21, so that the condensate can be discharged from the return water channel 11 and the return water port 31 by its own gravity, without the need for additional pressure to push the condensate to flow.

[0042] The outer side of the conveying pipe 1 has a heat insulation protective layer to reduce heat loss and ensure safety (preventing personnel from being burned or surrounding objects from being heated). The heat insulation protective layer is made of ceramic fiber cotton, glass fiber woven layer or aerogel felt.

[0043] The outer side of the conveying pipe 1 also has a flexible reinforcing layer to improve the tensile and torsional resistance of the conveying pipe 1. The flexible reinforcing layer is made of steel wire braided mesh or aramid fiber.

[0044] Combination Figures 2-4 The upper end of the steam conduit 2 is placed inside the delivery pipe 1. An outlet 22 is provided on the side wall of the upper end of the steam conduit 2. The outlet 22 connects the steam conduit 2 and the delivery pipe 1. Steam enters the steam channel 21 through the lower end of the steam conduit 2. Then, the steam enters the delivery pipe 1 through the steam channel 21 through the outlet 22. Finally, the steam enters the steam nozzle 6 from the upper end of the delivery pipe 1.

[0045] The vent 22 on the side wall of the steam conduit 2 prevents condensate from falling into the steam conduit 2 from the top, ensuring that the condensate is discharged smoothly along the predetermined path, while maintaining the stability of the steam transport inside the steam conduit 2, making the steam output efficient and reliable.

[0046] Combination Figure 2 and Figure 4 The upper end of the steam conduit 2 is located in the middle or upper half of the conveying pipe 1, that is, the upper end of the steam conduit 2 is located at the end of the conveying pipe 1 near the steam nozzle 6; the air outlet 22 is located in the middle or upper half of the conveying pipe 1, that is, the air outlet 22 is located at the end of the conveying pipe 1 near the steam nozzle 6, so that the steam can enter the conveying pipe 1 from the air outlet 22 and then enter the steam nozzle 6 connected to the upper end of the conveying pipe 1. At the same time, the pressure generated by the steam during operation can also act on the condensate in the lower half of the return water channel 11 and the return water outlet 31, thereby pushing the condensate to be discharged along the return water channel 11 and the return water outlet 31, improving the efficiency of condensate discharge.

[0047] Combination Figure 2 and Figure 3 The return water inlet 31 can be connected to the outside or to the main unit of the pressurized garment steamer. Alternatively, the return water inlet 31 can be equipped with a return water pipe 4, which connects the return water channel 11 and the water collection area of ​​the main unit of the pressurized garment steamer. The condensate in the return water channel 11 is introduced from the return water inlet 31 into the water collection area of ​​the main unit through the return water pipe 4.

[0048] Combination Figure 2 and Figure 3 The lower end of the conveying pipe 1 is equipped with a connecting joint 5. The connecting joint 5 is connected to the housing of the main unit by plugging and is prevented from separating from the housing of the main unit by a snap-fit. The connecting joint 5 is provided with an air inlet joint 51 and a water return joint 52. The upper end of the air inlet joint 51 is connected to the lower end of the steam pipe 2, that is, the upper end of the air inlet joint 51 is connected to the end of the steam pipe 2 that extends out of the conveying pipe 1, while the other end of the air inlet joint 51 (that is, the lower end of the air inlet joint 51) is connected to the steam generator inside the main unit. The upper end of the water return joint 52 is connected to the lower end of the water return pipe 4, and the lower end of the water return joint 52 is connected to the water collection area of ​​the main unit.

[0049] Combination Figure 2 , Figure 3 and Figure 5 The lower end of the conveying pipe 1 is provided with a connecting seat 3, which is used to seal the lower end of the conveying pipe 1. The connecting seat 3 is provided with an installation hole 32 and a return water port 31. The steam pipe 2 extends out of the lower end of the conveying pipe 1 through the installation hole 32, and the steam pipe 2 and the inner wall of the installation hole 32 are sealed together by interference fit, waterproof adhesive, or integral molding.

[0050] like Figure 3 and Figure 5 The connector 3 has a water outlet connector 33, the upper end of which is a water return port 31, and the lower end of which is used to insert and connect to the upper end of the water return pipe 4.

[0051] The upper end of the connector 3 has a connecting part 34 and a limiting part 35. The connecting part 34 is inserted into the conveying pipe 1. The connecting part 34 and the conveying pipe 1 are connected by socket connection, interference fit insertion or compression fitting. In this technical solution, the connecting part 34 is inserted into the lower end of the conveying pipe 1. The conveying pipe 1 or the connecting part 34 is sealed by elastic deformation or sealant. The limiting part 35 abuts against the lower end of the conveying pipe 1 to limit the length of the connecting part 34 placed inside the conveying pipe 1.

[0052] like Figure 5 A plurality of protruding rings 341 are provided on the outer side of the connecting part 34. A guide surface 342 is formed on the side of the protruding rings 341 facing away from the limiting part 35. The guide surface 342 is inclined towards the limiting part 35. The guide surface 342 is used to guide the connecting part 34 into the conveying pipe 1, so as to facilitate the connection between the connecting seat 3 and the conveying pipe 1.

[0053] The specific structure of the pressurized garment steamer can be found in the garment steamer body described in Chinese patent CN202322608115.6, and will not be repeated here.

[0054] Example 2:

[0055] The design scheme of this embodiment is basically the same as that of Embodiment 1, except that:

[0056] Combination Figure 6 The upper end of the steam conduit 2 has an opening 23. A water baffle 7 is provided at the upper end of the steam conduit 2. The water baffle 7 and the steam conduit 2 are connected by a sleeve, an interference fit, a plug, an adhesive connection, or are integrally formed. The water baffle 7 is placed above the opening 23. The water baffle 7 prevents condensate from falling from the upper end of the steam conduit 2 into the steam channel 21 inside the steam conduit 2. At least one through hole 71 is provided on the side end of the water baffle 7. The through hole 71 connects the steam conduit 2 and the conveying pipe 1. Steam enters the conveying pipe 1 through the steam channel 21, the opening 23 and the through hole 71 in sequence.
