Description

Technical Field

[0001] The utility model relates to the field of instant hot water faucets, in particular to an instant hot water faucet with a large flow rate. Background Art

[0002] Instant hot water faucets are faucets that can quickly deliver hot water. After turning on the instant hot water faucet, you can get hot water in a few seconds. Instant hot water faucets deliver hot water quickly and are very convenient for daily washing and cooking, so they are favored by young consumers.

[0003] There is a single-waterway instant hot water faucet in the prior art. This single-waterway instant hot water faucet has only one water pipe; a heating module is provided on the water pipe. When the user needs hot water, the heating module generates heat, so that the water temperature in the water pipe increases, and the water flowing out is hot water. When the user needs normal temperature water, the heating module does not generate heat, so that the water temperature in the water pipe does not increase, and the water flowing out is normal temperature water.

[0004] This type of single-waterway instant hot water faucet is usually set with a smaller water flow rate to prevent hot water from splashing and injuring people. If you want to obtain a larger flow of normal temperature water, you need to add an energy compensation device. This is because hot water and normal temperature water share the same waterway with a heating module, and the water resistance of the heating module is relatively large (the water resistance of the heating module is 200ml / min under a water pressure of 0.2MPa). Starting the energy compensation device can compensate for the energy consumed by the water resistance of the heating module, thereby obtaining a large flow of normal temperature water.

[0005] This type of single-water-channel instant hot water faucet has the following defects: 1. Obtaining a large flow of normal-temperature water requires the installation of an additional energy compensation device, which is costly; 2.

[0030] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.

The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0032] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and do not have to be used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0033] In addition, in the description of this application, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0034] It should be understood that the embodiments of the present application are not limited to the precise structures described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the embodiments of the present application is limited only by the appended claims.

[0035] The utility model aims to solve the problems of high cost and easy temperature crossover of the existing single-water-path instant hot water faucet, and changes the single water path into a double water path, that is, hot water and normal-temperature water flow out through two independent water pipes respectively. The heating module is only arranged on the water pipe through which the hot water passes, thereby avoiding the water resistance of the heating module affecting the flow of normal-temperature water, and no energy compensation device is required when obtaining a large flow of normal-temperature water, thereby reducing the cost. Since the hot water pipe and the normal-temperature water pipe are not intercommunication, the problem of temperature crossover will not occur.

[0036] Furthermore, the hot water flow rate of existing instant hot water faucets is usually relatively small. This is because existing instant hot water faucets cannot solve the problem that hot water is easy to splash and hurt people when the flow rate is large, so the hot water flow rate is limited. In view of the problem of small hot water flow rate, the utility model sets a rectifier net and an arc net at the water outlet to effectively prevent water splashing, so as to obtain a large flow of hot water.

[0037] Furthermore, when obtaining hot water, the existing instant hot water faucet generates a large amount of hot steam at the water outlet, which can easily scald people. For hot steam, the existing method of dealing with it is to add an electrically controlled exhaust valve and open the exhaust valve when obtaining hot water. This electrically controlled exhaust valve is not only expensive, but also requires the design of an electronic control program. In order to solve the problem of hot steam hurting people, the utility model provides a water vapor separation box and an exhaust pipe, so that hot steam is generated in the water vapor separation box, and the hot steam in the water vapor separation box is released through the exhaust pipe. This not only effectively prevents the problem of hot steam being generated at the water outlet and easily scalding people, but also does not require the installation of an electrically controlled exhaust valve, and the cost is relatively low.

[0038] Example 1

[0039] The large flow instant hot water faucet of embodiment 1 of the utility model comprises a faucet body 1, a water channel assembly 2 and a water outlet 3. The faucet body 1 is provided with an installation cavity, and the water channel assembly 2 is arranged in the installation cavity of the faucet body 1. The water outlet 3 is installed at the end of the faucet body 1. Hot water or normal temperature water can enter the water outlet 3 through the water channel assembly 2, and then flow out from the water outlet of the water outlet 3.

[0040] See also Figure 1-6 , Figure 1 This is a schematic diagram of the structure of a large-flow instant hot water faucet of the utility model; Figure 2 It is a structural schematic diagram of the hot water pipe and heating module of the large-flow instant hot water faucet of the utility model; Figure 3 It is a schematic diagram of the explosion disassembly of the water outlet of the large-flow instant hot water faucet of the utility model; Figure 4 It is a cross-sectional view of the water outlet of the large-flow instant hot water faucet of the utility model; Figure 5 It is a schematic diagram of the rectifying network structure of the water outlet of the large-flow instant hot faucet of the utility model; Figure 6 The utility model is a schematic diagram of the arc-shaped net structure of the water outlet of the large-flow instant hot water faucet.

[0041] Specifically, see Figure 1 The faucet body 1 includes a handle 11 and a cantilever 12. The mounting cavity passes through the handle 11 and the cantilever 12. The water spout 3 is mounted at the end of the cantilever 12. Preferably, the angle formed by the handle 11 and the cantilever 12 on the vertical plane is greater than or equal to 90°. Preferably, the cantilever 12 can rotate relative to the handle 11 on the horizontal plane.

[0042] Specifically, the water circuit assembly 2 includes: a hot water pipe 21, a normal temperature water pipe 22, a third pipe 23 and a heating module 24. The hot water pipe 21, the normal temperature water pipe 22 and the third pipe 23 are all independent pipes, which are located in the installation cavity of the faucet body 1 and pass through the handle 11 and the cantilever part 12 of the faucet body. In this embodiment, the third pipe 23 is an exhaust pipe.

[0043] The hot water pipe 21 includes a hot water pipe 211 in the handle section and a hot water pipe 212 in the cantilever section. Figure 2The heating module 24 includes a shell 241, an end cover 242 and a heating core tube 243. The heating core tube 243 is sleeved on the hot water pipe 211 of the handle section. The shell 241 includes a left shell 2411 and a right shell 2412. The left shell 2411 and the right shell 2412 surround the left side and the right side of the heating core tube 243 respectively. The left shell 2411 and the right shell 2412 are installed by snapping together, surrounding the entire side of the heating core tube 243, and playing the role of protecting the heating core tube 243. The inner surface of the shell 241 is also provided with a temperature sensor, which can detect the temperature of the surface of the heating core tube. The end cover 242 includes an upper end cover 2421 and a lower end cover 2422. The upper end cover 2421 and the lower end cover 2422 are respectively fixedly connected to the two ends of the heating core tube 243, and are fixedly sleeved on the hot water pipe 211 of the handle section, playing the role of fixing the heating core tube 243. When water flows through the hot water pipe 211 of the handle section, the heating core tube 243 generates heat, and the heat is transferred to the inside of the hot water pipe 211 through the outer wall of the hot water pipe 211, so that the water temperature in the hot water pipe 211 increases.

[0044] Specifically, see Figure 3 and Figure 4 The water outlet 3 includes a water vapor separation box 31, a rectifying net 32, a pressing ring 33, a lower cover 34 and an arc net 35.

[0045] The side wall of the water vapor separation box 31 is provided with the hot water inlet 311, the normal temperature water inlet 312 and the third port 313; the hot water inlet 311 is connected to the hot water pipe 21, the normal temperature water inlet 312 is connected to the normal temperature water pipe 22, and the third port 313 is connected to the third pipe 23. The bottom of the water vapor separation box 31 is provided with a rectifier net installation port and a protrusion 314; the outer periphery of the rectifier net installation port is provided with a sinking area; the protrusion 314 is cylindrical, extending out of the water vapor separation box 31, and perpendicular to the bottom of the water vapor separation box 31. In this embodiment, the third port 313 is an exhaust port.

[0046] See also Figure 5 , the rectifying net 32 ​​includes a water-permeable portion 321 at the bottom, a water-guiding portion 322 at the side, and a first fixed portion 323 at the top. The water-guiding portion 322 is trumpet-shaped with a larger top opening and a smaller bottom opening. The water-permeable portion 321 is a plane, connected to the inner side of the bottom opening of the water-guiding portion 322, and closes the bottom opening of the water-guiding portion 322. The first fixed portion 323 is annular, connected to the outer side of the top opening of the water-guiding portion, and surrounds the outer edge of the top opening of the water-guiding portion 322. The size of the first fixed portion 323 corresponds to the sinking area around the outer periphery of the rectifying net installation port of the water vapor separation box 31.

[0047] The rectifying net 32 ​​is installed in the rectifying net installation opening of the water vapor separation box, and its first fixing portion 323 is embedded in the sinking area around the rectifying net installation opening, and the water guide portion 322 and the water permeable portion 321 both extend out of the water vapor separation box 31. The protruding portion 314 of the water vapor separation box 31 surrounds the water guide portion 322 and the water permeable portion 321.

[0048] The pressing ring 33 is annular, and its size corresponds to the sunken area around the installation opening of the rectifying net of the water vapor separation box 31. The pressing ring 33 is installed in the sunken area around the installation opening of the rectifying net, and is pressed above the first fixing portion 323 of the rectifying net 32 ​​to fix the rectifying net 32.

[0049] The lower cover 34 is trumpet-shaped with a larger top opening and a smaller bottom opening. The top opening of the lower cover 34 is fixedly connected to the bottom edge of the water vapor separation box 31. The inner edge of the bottom opening of the lower cover 34 is provided with an arc-shaped net mounting platform. When the lower cover 34 is installed at the bottom of the water vapor separation box 31, the protrusion 314 of the water vapor separation box 31 is just engaged with the arc-shaped net mounting platform of the lower cover 34. The bottom opening of the lower cover 34 is the water outlet of the water outlet nozzle 3.

[0050] See also Figure 6 The arc net 35 includes an arc portion 351 and a second fixing portion 352. The arc portion 351 is an arc with a raised bottom. The second fixing portion 352 is an annular ring connected to the outer side of the arc portion and surrounds the outer edge of the arc portion 351. The size of the second fixing portion 352 corresponds to the arc net mounting platform.

[0051] The arc-shaped net 35 is installed on the arc-shaped net installation platform of the lower cover 34, and its second fixing part 352 is located above the arc-shaped net installation platform; the protrusion 314 of the water vapor separation box 31 is pressed above the second fixing part 352, which plays a role in fixing the arc-shaped net 35.

[0052] Furthermore, the water vapor separation box of the water outlet nozzle further includes an upper cover 36. The upper cover 36 is detachable and covers the top of the water vapor separation box 31. By removing the upper cover 36, the water vapor separation box 31 can be easily cleaned, and the rectifying net 32 ​​and the arc net 35 can be installed.

[0053] Hot water or normal temperature water can enter the inner cavity of the water vapor separation box 31 through the hot water pipe 21 or the normal temperature water pipe 22, through the hot water inlet 311 or the normal temperature water inlet 312, and then pass through the rectifying net 32 ​​and the arc net 35 to flow out from the bottom opening of the lower cover 34. When hot water enters the inner cavity of the water vapor separation box 31, hot steam is generated in the inner cavity of the water vapor separation box 31 due to the large inner cavity space of the water vapor separation box 31; the hot steam is discharged through the exhaust port 313 and the exhaust pipe 23.

[0054] The large flow instant hot water faucet of the utility model embodiment 1 has the following beneficial effects:

[0055] 1. Hot water and normal temperature water flow out through independent hot water pipes and normal temperature water pipes respectively. Only the heating module is set on the hot water pipe, so as to avoid the water resistance of the heating module affecting the flow of normal temperature water. When obtaining large flow of normal temperature water, energy compensation device is no longer required, which reduces the cost. The hot water pipe and the normal temperature water pipe are not intercommunication, which effectively avoids the problem of temperature crossover.

[0056] 2. Since the inner cavity of the water vapor separation box is large and the inner diameter of the protrusion is small, the scattered and turbulent water flow in the inner cavity will converge under the action of gravity, and then be shaped by the rectifying net and the arc net to become a water column with a regular water shape. The shape design of the water outlet of the utility model and the setting of the rectifying net and the arc net prevent the water flowing out of the water outlet from splashing randomly. Even if the hot water is discharged at a large flow rate, it is not easy to scald people, so there is no need to limit the hot water flow rate, and the effect of hot water being able to be discharged at both a small flow rate and a large flow rate is achieved.

[0057] 3. When hot water enters the inner cavity of the water vapor separation box, hot steam will be generated in the inner cavity of the water vapor separation box due to the large space of the inner cavity of the water vapor separation box. The hot steam can enter the exhaust pipe through the exhaust port of the water vapor separation box and be discharged, reducing the probability of hot steam scalding people. The water vapor separation box and the exhaust pipe of the utility model do not require an electrically controlled exhaust valve, and the cost is low.

[0058] Example 2

[0059] The large flow instant hot water faucet of Example 2 of the utility model is basically the same as the large flow instant hot water faucet of Example 1, except that in Example 2, the third pipe 23 of the water channel assembly 2 is a warm water pipe, and the third port 313 of the water vapor separation box 31 of the water outlet 3 is a warm water inlet. The warm water pipe is connected to the warm water inlet.

[0060] Warm water enters the inner cavity of the water vapor separation box 31 through the warm water pipe 23 and the warm water inlet 313 , and then flows out from the bottom opening of the lower cover 34 after being shaped by the rectifying net 32 ​​and the arc net 35 .

[0061] In this embodiment, the hot water refers to water with a temperature between 80°C and 95°C; the warm water refers to water with a temperature between room temperature and 75°C; and the normal temperature water refers to water with a temperature approximately equal to room temperature.

[0062] Compared with Example 1, the physical structure of the third tube 23 and the third port 313 remains unchanged. When warm water flows in the third tube 23, the third tube 23 is a warm water tube, and the third port 313 is a warm water inlet, which plays the role of circulating warm water and preventing temperature leakage; at this time, the large-flow instant hot faucet of the utility model is a three-waterway instant hot faucet. When there is no water in the third tube 23, the third tube 23 is an exhaust pipe, and the third port 313 is an exhaust port, which plays the role of exhausting the hot steam in the water vapor separation box; at this time, the large-flow instant hot faucet of the utility model is a double-waterway instant hot faucet.

[0063] The large flow instant hot water faucet of the second embodiment of the utility model has the following beneficial effects: hot water, warm water and normal temperature water flow out through independent hot water pipes, warm water pipes and normal temperature water pipes respectively. The three waterways operate independently and are not interconnected, which effectively avoids the problem of temperature leakage.

[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
