Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a hot water purifier with a hot water tank exhaust liquefaction structure. Background Technology

[0002] With the improvement of living standards, most families now have water purifiers installed. These water purifiers have a heating tank inside to store and heat purified water. Existing heating tanks are usually connected to a raw water inlet and a hot water outlet. However, the heating process generates a large amount of steam. Excessive steam can cause the pressure inside the heating tank to be too high, which may damage the tank. In addition, the excessive steam pressure inside the heating tank can also cause the water pressure at the hot water outlet to be too high, resulting in an excessively fast flow rate of hot water from the water purifier, and even hot water spraying out and causing scalding. This needs to be improved urgently. Utility Model Content

[0003] The purpose of this invention is to provide a hot water tank exhaust liquefaction structure and a water purifier with the same structure, which can effectively depressurize the hot water tank and reduce the amount of steam emitted during the depressurization process.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hot tank exhaust liquefaction structure, including a condensate return component fixed on the hot tank and a steam discharge pipe installed on the condensate return component. The condensate return component has a vapor-liquid mixing chamber, and the steam discharge pipe has a steam exhaust channel communicating with the vapor-liquid mixing chamber. The inlet end of the steam exhaust channel communicates with the inner cavity of the hot tank through the vapor-liquid mixing chamber. A condensate space is formed between the inner wall of the vapor-liquid mixing chamber and the outer wall of the steam discharge pipe. Steam gathers on the inner wall of the condensate space to form liquid and flows back to the hot tank through the vapor-liquid mixing chamber.

[0005] By adopting the above technical solution, after steam enters the vapor-liquid mixing chamber, a portion of the high-temperature steam is discharged from the exhaust channel of the steam discharge pipe, thereby releasing the pressure inside the hot tank. Another portion of the steam comes into contact with the inner wall of the vapor-liquid mixing chamber or the outer wall of the steam discharge pipe, and condenses into water droplets on the inner wall of the condensate space. The water droplets flow back into the hot tank from top to bottom through the vapor-liquid mixing chamber by gravity, thus achieving partial recovery of steam. This utility model forms a condensate space between the inner wall of the vapor-liquid mixing chamber and the outer wall of the steam discharge pipe, and uses the condensate space to recover steam during the depressurization process of the hot tank, reducing the amount of steam emitted during depressurization. It has the effect of effectively depressurizing the hot tank and reducing the amount of steam emitted during the depressurization process of the hot tank.

[0006] A further feature of this invention is that the outer wall of the steam discharge pipe has a mounting portion extending radially, and the steam discharge pipe is sealed to the condensate return component through the mounting portion.

[0007] By adopting the above technical solution, the sealed connection between the mounting part and the end face of the condensate return component can ensure that the condensate space will not leak. Optionally, the connection between the mounting part and the end of the condensate return component can be achieved by laser welding or plug-in connection.

[0008] A further feature of this invention is that: a guide member is connected to one end of the condensate return member near the exhaust channel; the guide member has a steam inlet channel and a liquid return hole that are interconnected; one end of the steam inlet channel is connected to the hot tank, and the other end of the steam inlet channel is connected to the vapor-liquid mixing chamber; the liquid return hole is opened through the side wall of the guide member and is connected to the steam inlet channel; the liquid condensed and returned in the vapor-liquid mixing chamber returns to the hot tank through the liquid return hole.

[0009] By adopting the above technical solution, steam flows into the vapor-liquid mixing chamber through the steam inlet channel, while the condensed liquid in the condensate space can slide down the inner wall of the vapor-liquid mixing chamber to the liquid return hole, and then flow back to the hot tank for recycling through the liquid return hole.

[0010] A further feature of this invention is that the steam inlet channel includes a horizontal section and a vertical section that are interconnected, the extension directions of the horizontal section and the vertical section are perpendicular to each other, and the inlet end of the horizontal section is connected to the hot tank, and the end of the vertical section away from the horizontal section is connected to the vapor-liquid mixing chamber.

[0011] By adopting the above technical solution, the steam inlet channel is made into an L-shaped channel structure, so that the inlet end of the horizontal section is closer to the top of the hot tank, thereby ensuring that the steam at the top of the hot tank can preferentially enter the inlet end of the steam inlet channel. Optionally, the inner diameter of the horizontal section is larger than the liquid reflux hole, thereby ensuring that the steam can enter the steam inlet channel from the inlet end of the horizontal section in a large flow.

[0012] A further feature of this invention is that the liquid return hole is connected to the bottom of the horizontal section and is located close to the vertical section, with the liquid return hole situated within the vertical projection area of ​​the vertical section.

[0013] By adopting the above technical solution, the liquid returning from the condensate space passes through the vertical section and then directly flows into the direct-flow reheat tank through the liquid return orifice at the bottom of the vertical section, thereby improving the efficiency of the return liquid flowing back into the reheat tank.

[0014] A further feature of this invention is that the condensate return component includes a connecting portion, one end of the vapor-liquid mixing chamber passes through the connecting portion, and the vertical section is threadedly connected to the connecting portion.

[0015] By adopting the above technical solution, the condensate return component can be detachably installed on the hot tank, making it convenient to replace or clean the condensate return component.

[0016] A water purifier includes a heating tank and a heating tank exhaust liquefaction structure.

[0017] A further feature of this invention is that the hot tank is equipped with a liquid level detection module, the liquid level detection module includes several water level probes, the liquid level detection module is located on the top of the hot tank and near the center, and the hot tank exhaust liquefaction structure is installed on the top of the hot tank and spaced apart from the side of the liquid level detection module.

[0018] By adopting the above technical solution, the liquid level detection module can monitor the water level in the hot tank in real time. In addition, setting the liquid level detection module at the center of the top of the hot tank can improve the accuracy of the liquid level detection module in detecting the water level in the hot tank. At the same time, setting the hot tank exhaust liquefaction structure interval on the side of the liquid level detection module is beneficial to improving the modularity of the various functions of this utility model.

[0019] A further feature of this invention is that the bottom of the hot tank is provided with a heating area, the heating area is provided with a heating element, and the vertical projection of the liquid level detection module overlaps with the heating area.

[0020] By adopting the above technical solution, the heating element is used to heat the heating area, thereby raising the temperature of the liquid in the hot tank to prepare hot water. This utility model aligns the heating area below the liquid level detection module, which can improve the uniformity of hot water temperature rise in various areas of the hot tank.

[0021] A further feature of this invention is that the steam discharge pipe is arranged horizontally relative to the hot tank, such that the steam discharge direction of the exhaust channel is perpendicular to the arrangement direction of the water level probe.

[0022] By adopting the above technical solution, unlike vertically arranged steam discharge pipes which easily lead to steam being discharged directly upwards, resulting in significant steam loss, this utility model sets the steam discharge pipe horizontally relative to the hot tank. This allows the steam from the top of the hot tank to be lifted upwards through the vapor-liquid mixing chamber and then bend and change direction through the horizontally arranged steam discharge pipe, thereby slowing down the steam discharge rate. This gives the steam more opportunities to contact the inner wall of the vapor-liquid mixing chamber and the outer wall of the steam discharge pipe, allowing more steam to condense on the inner wall of the condensate space to form a backflow liquid, thus reducing steam loss during hot tank depressurization.

[0023] In summary, this utility model has the following beneficial effects:

[0024] A condensate reflux device is installed at the top of the hot tank, and a steam exhaust pipe is mounted on the condensate reflux device. The condensate reflux device has a vapor-liquid mixing chamber, and the steam exhaust pipe has a steam venting channel connecting to the vapor-liquid mixing chamber. A guide device is connected to the connection of the condensate reflux device, and the guide device has a steam inlet channel and a liquid reflux hole. After the steam enters the vapor-liquid mixing chamber through the steam inlet channel, a portion of the high-temperature steam is discharged from the steam exhaust channel of the steam exhaust pipe, thereby releasing the pressure inside the hot tank. The remaining steam contacts... After passing through the inner wall of the vapor-liquid mixing chamber or the outer wall of the steam discharge pipe, water droplets condense on the inner wall of the condensate space. The water droplets flow back into the hot tank from top to bottom by gravity through the vapor-liquid mixing chamber and the liquid return hole, thus achieving partial recovery of steam. This utility model forms a condensate space between the inner wall of the vapor-liquid mixing chamber and the outer wall of the steam discharge pipe, and uses the condensate space to recover steam during the depressurization process of the hot tank, reducing the amount of steam emitted during depressurization. It has the effect of effectively depressurizing the hot tank and reducing the amount of steam emitted during the depressurization process of the hot tank. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] A hot tank exhaust liquefaction structure, such as Figures 1-5 As shown, it includes a condensate return component 1 fixed on the hot tank 4 and a steam discharge pipe 2 installed on the condensate return component 1. The condensate return component 1 has a vapor-liquid mixing chamber 11, and the steam discharge pipe 2 has a steam exhaust channel 21 that connects to the vapor-liquid mixing chamber 11. The inlet end of the steam exhaust channel 21 is connected to the inner cavity of the hot tank 4 through the vapor-liquid mixing chamber 11. A condensate space 12 is formed between the inner wall of the vapor-liquid mixing chamber 11 and the outer wall of the steam discharge pipe 2. Steam gathers on the inner wall of the condensate space 12 to form liquid and flows back to the hot tank 4 through the vapor-liquid mixing chamber 11.

[0035] like Figures 2-5 As shown, the outer wall of the steam discharge pipe 2 extends radially with an installation part 22. The steam discharge pipe 2 is sealed to the condensate return component 1 through the installation part 22. The sealed connection between the installation part 22 and the end face of the condensate return component 1 ensures that the condensate space 12 will not leak. Optionally, the installation part 22 and the end of the condensate return component 1 can be connected by laser welding or plugging. The end of the condensate return component 1 near the exhaust channel 21 is connected to a guide component 3. The guide component 3 has a steam inlet channel 31 and a liquid return hole 32 that are interconnected. One end of the steam inlet channel 31 is connected to the hot tank 4, and the other end of the steam inlet channel 31 is connected to the vapor-liquid mixing chamber 11. The liquid return hole 32 is opened through the side wall of the guide component 3 and is connected to the steam inlet channel 31. The liquid condensed and returned in the vapor-liquid mixing chamber 11 flows back to the hot tank 4 through the liquid return hole 32. The steam flows to the vapor-liquid mixing chamber 11 through the steam inlet channel 31, while the condensate in the condensate space 12 is condensed. The liquid can slide down the inner wall of the vapor-liquid mixing chamber 11 to the liquid return hole 32, and then flow back to the hot tank 4 for recycling through the liquid return hole 32; the condensate return component 1 includes a connecting part 13, one end of the vapor-liquid mixing chamber 11 passes through the connecting part 13, and the vertical section 312 is threadedly connected to the connecting part 13, so that the condensate return component 1 can be detachably installed on the hot tank 4, which facilitates the replacement or cleaning of the condensate return component 1; in this embodiment, the top of the hot tank 4 is provided with an installation hole corresponding to the connecting part 13, for connection After passing through the mounting hole, part 13 is threadedly connected to the vertical section 312 of the guide member 3, so that the guide member 3 and the condensate return member 1 together hold the top of the hot tank 4; and the bottom surface of the condensate space 12 is provided with a guide slope 121 from the position away from the connecting part 13 toward the direction close to the connecting part 13. Water droplets condensed on the inner wall of the condensate space 12 can be gathered to the connecting part 13 by the guide slope 121, and flow to the vertical section 312 of the guide member 3 through the vapor-liquid mixing chamber 11 of the connecting part 13.

[0036] like Figures 3-5As shown, the steam inlet channel 31 includes a horizontal section 311 and a vertical section 312 that are interconnected. The extension directions of the horizontal section 311 and the vertical section 312 are perpendicular to each other. The inlet end of the horizontal section 311 is connected to the hot tank 4, and the end of the vertical section 312 away from the horizontal section 311 is connected to the vapor-liquid mixing chamber 11. This makes the steam inlet channel 31 have an L-shaped channel structure, so that the inlet end of the horizontal section 311 is closer to the top of the hot tank 4, thereby ensuring that the steam at the top of the hot tank 4 can preferentially enter the inlet end of the steam inlet channel 31. Optionally, the horizontal section 31... The inner diameter of section 1 is larger than that of the liquid return hole 32, thereby ensuring that steam can enter the steam inlet channel 31 from the inlet end of the horizontal section 311 in a large flow. The liquid return hole 32 is connected to the bottom of the horizontal section 311 and is set close to the vertical section 312. The liquid return hole 32 is located within the vertical projection area of ​​the vertical section 312, so that the liquid returning from the condensate space 12 passes through the vertical section 312 and directly flows into the reheat tank 4 from the liquid return hole 32 at the bottom of the vertical section 312, which improves the efficiency of the return liquid flowing into the reheat tank 4.

[0037] Another technical objective of this utility model is to provide a water purifier, such as... Figures 1-7As shown, the device includes a hot tank 4 and the aforementioned venting and liquefaction structure of the hot tank 4. The hot tank 4 is equipped with a liquid level detection module 41, which includes several water level probes 411. The liquid level detection module 41 is located on the top of the hot tank 4 and near its center. The venting and liquefaction structure of the hot tank 4 is installed on the top of the hot tank 4 and spaced apart on the sides of the liquid level detection module 41. The liquid level detection module 41 can monitor the water level in the hot tank 4 in real time. Furthermore, placing the liquid level detection module 41 at the center of the top of the hot tank 4 improves the accuracy of the liquid level detection module 41 in detecting the water level in the hot tank 4. Simultaneously, the spaced arrangement of the venting and liquefaction structure on the sides of the liquid level detection module 41 enhances the modularity of the various functions integrated in this invention. The bottom of the hot tank 4 is provided with a heating area 42, which contains heating elements 421. The vertical projection of the liquid level detection module 41 overlaps with the heating area 42. The heating elements 421 are used to heat the heating area 42, thereby... To heat the liquid in the hot tank 4 and prepare hot water, this invention aligns the heating area 42 below the liquid level detection module 41, which improves the uniformity of hot water heating in various areas of the hot tank 4. The steam discharge pipe 2 is arranged horizontally relative to the hot tank 4, so that the steam discharge direction of the steam exhaust channel 21 is perpendicular to the arrangement direction of the water level probe 411. Unlike the vertically arranged steam discharge pipe 2, which easily leads to steam being discharged directly upwards and resulting in large steam loss, this invention arranges the steam discharge pipe 2 horizontally relative to the hot tank 4. This allows the steam from the top of the hot tank 4 to be lifted upwards through the vapor-liquid mixing chamber 11 and then bend and change direction through the horizontally arranged steam discharge pipe 2, thereby slowing down the steam discharge rate. This allows the steam to have more opportunities to contact the inner wall of the vapor-liquid mixing chamber 11 and the outer wall of the steam discharge pipe 2, so that more steam can condense on the inner wall of the condensate space 12 to form backflow liquid, thereby reducing the steam loss when the hot tank 4 is depressurized.

[0038] The basic working principle of this utility model is as follows: A condensate return component 1 is installed on the top of the hot tank 4, and a steam discharge pipe 2 is installed on the condensate return component 1. The condensate return component 1 has a vapor-liquid mixing chamber 11, and the steam discharge pipe 2 has a steam exhaust channel 21 that connects to the vapor-liquid mixing chamber 11. At the same time, a guide component 3 is connected to the connecting part 13 of the condensate return component 1. The guide component 3 has a steam inlet channel 31 and a liquid return hole 32. After the steam enters the vapor-liquid mixing chamber 11 through the steam inlet channel 31, a portion of the high-temperature steam is discharged from the steam exhaust channel 21 of the steam discharge pipe 2, thereby reducing the pressure inside the hot tank 4. After the release, another portion of the steam comes into contact with the inner wall of the vapor-liquid mixing chamber 11 or the outer wall of the steam discharge pipe 2, and condenses into water droplets on the inner wall of the condensate space 12. The water droplets flow back into the hot tank 4 from top to bottom by gravity through the vapor-liquid mixing chamber 11 and the liquid return hole 32, thus achieving partial recovery of steam. This utility model forms a condensate space 12 between the inner wall of the vapor-liquid mixing chamber 11 and the outer wall of the steam discharge pipe 2, and uses the condensate space 12 to realize the recovery of steam during the depressurization process of the hot tank 4, thereby reducing the amount of steam emitted during depressurization. It has the effect of effectively depressurizing the hot tank and reducing the amount of steam emitted during the depressurization process of the hot tank.
