Description

Technical Field

[0001] This utility model relates to the field of heat recovery technology, specifically a heat recovery energy-saving device for garment ironing equipment. Background Technology

[0002] Heat recovery energy-saving devices are a technology that recovers and reuses waste heat. The aim is to improve energy efficiency, reduce energy waste, and lower energy costs. The recovery system uses a heat exchanger to transfer heat from waste gas and wastewater to intake air or other media that need to be heated, thereby reducing additional heating requirements.

[0003] Steam irons require a steam generator to supply steam during use. Made of metal, steam irons continuously dissipate heat during operation, producing condensation. Therefore, an iron has a drain system, requiring continuous drainage to ensure clothes remain dry after ironing. However, this drainage process also releases hot steam and water, resulting in energy waste. To address this, a dedicated heat recovery energy-saving device for garment ironing equipment is proposed to improve energy efficiency during iron use. Utility Model Content

[0004] To solve the above-mentioned technical problems, a heat recovery energy-saving device for garment ironing equipment is provided. This technical solution solves the problem of energy waste caused by condensation and high-temperature steam discharge during iron use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A heat recovery energy-saving device for garment ironing equipment includes an outer tube, a liquid storage tank, and a connecting flange. The liquid storage tank is located inside the outer tube. The upper end of the liquid storage tank is bolted to the connecting flange. A water supply pipe is connected to the top of the connecting flange. Hot water in the liquid storage tank is input to a steam generator through the water supply pipe. A steam inlet pipe is connected to one side of the upper end of the outer tube. The steam inlet pipe is connected to the drain outlet of the iron. A waste liquid discharge pipe is provided at the lower end of the steam inlet pipe. The waste liquid discharge pipe is connected to the interior of the outer tube.

[0007] The outer tube is provided with spiral fins inside. The spiral fins are welded to the outside of the liquid storage tank. The outside of the spiral fins is in close contact with the inner wall of the outer tube. The spiral fins are spirally arranged and water guide grooves are formed between the fins. The spiral fins are used to heat the liquid in the liquid storage tank after absorbing heat.

[0008] Preferably, a first connecting plate is welded to the upper end of the liquid storage tank, and the outer side of the first connecting plate is welded and fixed to the upper end of the outer tube.

[0009] Preferably, a third connecting plate is welded to the bottom of the liquid storage tank, and a water injection pipe is connected to the lower end of the third connecting plate, which is connected to an external water tank.

[0010] Preferably, the upper end of the liquid storage tank is provided with multiple threaded holes, which are evenly arranged in a circle. The upper end of the connecting flange is provided with multiple connecting holes, which are corresponding to the threaded holes. The threaded holes are threadedly connected to the connecting holes by bolts.

[0011] Preferably, a second connecting plate is welded to the lower end of the outer tube, and a through hole is opened in the middle of the second connecting plate. The liquid storage tank is sleeved inside the through hole, and the outer wall of the liquid storage tank is welded and fixed to the second connecting plate.

[0012] Preferably, the outer tube is covered with insulating cotton.

[0013] The advantages of this utility model compared with the prior art are:

[0014] 1. This utility model is equipped with an outer tube and a liquid storage tank. The surface of the liquid storage tank is welded with spiral fins. During the heat dissipation process of the iron, the cooling water mixed with some steam flows into the outer tube through the steam inlet pipe. The heat of the cooling water and steam is absorbed by the spiral fins to heat the cold water in the liquid storage tank. The cooled condensate flows downward along the spiral fins and is discharged through the waste liquid discharge pipe. When the steam generator needs to be replenished with water, the hot water in the liquid storage tank is discharged into the steam generator through the water supply pipe. Adding hot water to the steam generator can prevent the steam generator temperature from dropping suddenly, which would cause a pressure drop and affect normal operation. Afterwards, cold water is injected into the liquid storage tank from the external water tank through the water injection pipe, and the waste heat generated by the iron is recovered again to heat the cold water, which improves the energy utilization efficiency.

[0015] 2. The upper end of the liquid storage tank is connected to a connecting flange. After long-term use, scale will accumulate inside the liquid storage tank due to the storage of hot water. At this time, the connecting flange can be removed to clean the scale inside the liquid storage tank, which can improve the heat recovery efficiency. At the same time, the device can be reused, reducing the operating cost. Attached Figure Description

It is understood that the accompanying drawings are provided for reference and illustration only and are not intended to limit the present utility model. The connection relationships shown in the drawings are only for clear description and do not limit the connection method.

[0021] like Figure 1-2 As shown, a heat recovery energy-saving device for garment ironing equipment includes an outer tube body 1, a liquid storage tank 2, and a connecting flange 3. The liquid storage tank 2 is disposed inside the outer tube body 1. A steam inlet pipe 11 is connected to one side of the upper end of the outer tube body 1. The steam inlet pipe 11 is connected to the drain outlet of the iron. The condensate and steam discharged from the iron enter the interior of the outer tube body 1 through the steam inlet pipe 11. Spiral fins 22 are disposed inside the outer tube body 1. The spiral fins 22 are welded to the outside of the liquid storage tank 2. The outside of the spiral fins 22 is in close contact with the inner wall of the outer tube body 1. The spiral fins 22 are spirally arranged, and a spiral groove is formed between the fins. The water guide channel and the spiral fins 22 are used to heat the liquid in the storage tank 2 after absorbing heat. After the condensate and steam enter the outer tube 1, they come into contact with the spiral fins 22. The spiral fins 22 absorb the heat of the condensate and steam to heat the cold water in the storage tank 2. The condensate flows spirally downward along the water guide channel. The lower end of the steam inlet pipe 11 is provided with a waste liquid discharge pipe 12. The waste liquid discharge pipe 12 is connected to the inside of the outer tube 1. The cooled condensate is discharged to the external water storage tank through the waste liquid discharge pipe 12. The outer side of the outer tube 1 is covered with heat insulation cotton to prevent heat loss through the outer tube 1.

[0022] The upper end of the liquid storage tank 2 is welded with a first connecting plate 4. The outer side of the first connecting plate 4 is welded and fixed to the upper end of the outer pipe 1. The upper end of the liquid storage tank 2 is connected to a connecting flange 3 by bolts. The top of the connecting flange 3 is connected to a water supply pipe 31. The hot water in the liquid storage tank 2 is input to the steam generator through the water supply pipe 31. Adding hot water to the steam generator can prevent the steam generator temperature from dropping suddenly, which would cause a pressure drop and affect normal operation. The bottom of the liquid storage tank 2 is welded with a third connecting plate 6. The lower end of the third connecting plate 6 is connected to a water injection pipe 61. The water injection pipe 61 is connected to an external water tank. The water in the water tank is pumped to the liquid storage tank 2 for heating.

[0023] like Figure 2 As shown, the upper end of the liquid storage tank 2 is provided with multiple threaded holes 21, which are evenly arranged in a circle. The upper end of the connecting flange 3 is provided with multiple connecting holes 32, which are corresponding to the threaded holes 21. The threaded holes 21 are threadedly connected to the connecting holes 32 by bolts. The lower end of the outer tube body 1 is welded with a second connecting plate 5, which has a through hole in the middle. The liquid storage tank 2 is fitted inside the through hole, and the outer wall of the liquid storage tank 2 is welded and fixed to the second connecting plate 5.

[0024] After prolonged use, scale will accumulate inside the liquid storage tank 2 due to the storage of hot water. At this time, the connecting flange 3 can be removed to clean the scale inside the liquid storage tank, allowing it to be reused and reducing operating costs.

[0025] The principle of this invention is as follows: During the heat dissipation process of the iron, the cooling water mixed with some steam flows into the outer tube 1 through the steam inlet pipe 11. The heat of the cooling water and steam is absorbed by the spiral fins 22 to heat the cold water in the storage tank 2. The cooled condensate flows downward along the spiral fins 22 and is discharged through the waste liquid discharge pipe 12. When the steam generator needs to be replenished with water, the hot water in the storage tank 2 is discharged into the steam generator through the water supply pipe 31. Adding hot water to the steam generator can prevent the steam generator temperature from dropping suddenly, which would cause a decrease in pressure and affect normal operation. Afterwards, cold water is injected into the storage tank 2 from the external water tank through the water injection pipe 61, and the waste heat generated by the iron is recovered again to heat the cold water, which improves the energy utilization efficiency.
