[0004] However, the overall size of the pre-purification module of the water heater is relatively large. Utility Model Content

[0005] Embodiments of the present application provide a pre-purification module for a water heater and a water heater, and the overall size of the pre-purification module of the water heater is relatively small.

[0006] In a first aspect, embodiments of the present application provide a pre-purification module for a water heater, including:

[0007] A housing, the housing is configured with an inner cavity. The housing includes a main body and a connecting portion that are communicated with each other. The connecting portion is located on one side of the main body. Along a first direction, the height of the connecting portion is less than the height of the main body;

[0008] A filtering assembly, the filtering assembly is located inside the inner cavity;

[0009] An inlet structure, the inlet structure is connected to the connecting portion and is communicated with the inner cavity. The extending direction of the inlet structure is the same as the extending direction of the housing;

[0010] An outlet structure, the outlet structure is connected to the connecting portion and is communicated with the inner cavity. The extending direction of the outlet structure is the same as the first direction;

[0011] Wherein, the first direction has an included angle with the extending direction of the housing.

[0012] In this way, the size of the pre-purification module of the water heater along the extending direction of the outlet structure is the sum of the length of the outlet structure and the size of a part of the housing. The size of the pre-purification module of the water heater along the extending direction of the outlet structure is relatively small after installation, which is beneficial to the hidden installation of the pre-purification module of the water heater.

[0013] In some embodiments of the present application, the extending direction of the outlet structure is perpendicular to the extending direction of the inlet structure.

[0014] In this way, it is beneficial to meet the daily usage habits of users, facilitate the connection between the water outlet structure and the water inlet end of the water heater body, and facilitate the connection between the water inlet structure and the external water source.

[0016] The connecting part is connected to the bottle cap, the water inlet structure is located on the side of the connecting part facing the bottle body, and the extending direction of the water inlet structure is consistent with the axial direction of the body;

[0017] The water outlet structure and the water inlet structure are located on different sides of the connecting part, and the extending direction of the water outlet structure is consistent with the radial direction of the body.

[0023] At least two fourth cavities are arranged along the extending direction of the cartridge. The fourth cavity at one end along the extending direction of the cartridge is communicated with the inlet cavity, and the fourth cavity at the other end is communicated with the outlet cavity.

[0024] In this way, when the water flow passes through the filter element assembly, the cross-sectional area of the water flow channel is relatively large, and it is not easy to reduce the water flow rate.

[0025] In some embodiments of the present application, the cartridge includes a cartridge body and at least one partition board. At least one partition board is located inside the cartridge body to divide the inside of the cartridge body into at least two fourth cavities;

[0026] A communication port is arranged on the partition board, and the size of the communication port is smaller than the size of the filter media.

[0029] The barrel body is provided with a water outlet, which communicates with the water outlet cavity and another fourth cavity.

[0030] In this way, when the size of the barrel body is constant, water passes through all the fourth cavities in the barrel in sequence, which is beneficial to improving the filtering effect.

[0031] In some embodiments of the present application, the filter assembly includes a filter element, the filter element is located in the water inlet cavity, and the cover is arranged on the water inlet.

[0032] In this way, the filter element can perform preliminary filtering on the water, thereby improving the water purification effect. Moreover, by arranging the filter element, the filter element cover is arranged on the water inlet, effectively preventing the filter material from leaking out through the water inlet.

[0056] As described in the background art, the water heater pre - purification module includes a housing and a filter element. The filter element is located inside the housing. The housing is circumferentially provided with an inlet structure and an outlet structure at intervals. The inlet structure and the outlet structure are communicated with the housing. Water enters the filter element through the inlet structure and flows to the water heater through the outlet structure after being filtered by the filter element.

[0057] Among them, the extending direction of the inlet structure is perpendicular to the extending direction of the housing, and the extending direction of the outlet structure is perpendicular to the extending direction of the housing. The extending direction of the inlet structure is perpendicular to the extending direction of the outlet structure. The outlet structure of the water heater pre - purification module is connected to the inlet end of the water heater, and the outlet structure faces the body of the water heater. Since the extending direction of the outlet structure is perpendicular to the extending direction of the housing, the size of the water heater pre - purification module along the extending direction of the outlet structure is relatively large after installation, and the size is the sum of the length of the outlet structure and the size of the housing. In this way, it is not conducive to the hidden installation of the water heater pre - purification module.

[0058] To solve the above - mentioned technical problems, in the water heater pre - purification module of the present application, by providing a connecting part, the connecting part is located on one side of the body, and along the first direction, the height of the connecting part is less than that of the body. The outlet structure is connected to the connecting part, and the extending direction of the outlet structure is the same as the extending direction of the housing. In this way, the size of the water heater pre - purification module along the extending direction of the outlet structure is the sum of the length of the outlet structure and the size of a part of the housing. The size of the water heater pre - purification module along the extending direction of the outlet structure is relatively small after installation, which is conducive to the hidden installation of the water heater pre - purification module.

[0068] Among them, the water heater body 100 is configured with a water inlet end 110, and the water outlet structure of the pre-purification module 200 for the water heater is connected to the water inlet end 110. In this way, the water enters the water heater body 100 after being purified, which is beneficial to improving the service life of the water heater.

[0069] In some embodiments, the water heater further includes a safety valve 300.

[0070] Among them, the safety valve 300 is connected to the water inlet end 110, and the water outlet structure of the pre-purification module 200 for the water heater is connected to the safety valve 300.

[0071] In some embodiments, the water heater includes a hidden cover, and the hidden cover covers the pre-purification module 200 for the water heater.

[0072] It should be noted that the water heater can be an electric water heater, a gas water heater, a solar water heater or a heat pump water heater. The structure of the pre-purification module 200 for the water heater is simple and has strong versatility, can be applied to a variety of products, and can also adopt different installation methods according to the environment.

[0073] Next, the specific structure of the pre-purification module 200 for the water heater will be introduced.

[0074] Figure 6 It is a schematic structural diagram of the pre-purification module for the water heater provided in an embodiment of the present application. Figure 7 It is a schematic structural diagram of the pre-purification module for the water heater from another angle provided in an embodiment of the present application. Figure 8Exploded view of the pre - purification module for a water heater provided by an embodiment of the present application.

[0075] Refer to Figures 6 to 8 As shown, an embodiment of the present application provides a pre - purification module 200 for a water heater, including: a housing 210. The housing 210 can play a role in protection and aesthetics.

[0076] Among them, the housing 210 is configured with an inner cavity. The inner cavity is used to accommodate the filter assembly and for water circulation.

[0077] In some embodiments, the housing 210 includes a main body 211 and a connecting portion 212 that are interconnected. The main body 211 and the connecting portion 212 together form the inner cavity.

[0078] Among them, the connecting portion 212 is located on one side of the main body 211. Along the first direction, the height of the connecting portion 212 is less than the height of the main body 211.

[0079] Exemplarily, the connecting portion 212 can be located at the end side of the main body 211, or the connecting portion 212 can be located at a position in the circumferential direction of the main body 211.

[0080] It should be noted that the first direction can be the direction shown by the Y - axis in the figure.

[0081] In some embodiments, the pre - purification module 200 for a water heater includes a filter assembly 220. The filter assembly 220 is located in the inner cavity. The filter assembly 220 is used to purify water.

[0082] In some embodiments, the pre - purification module 200 for a water heater includes a water inlet structure 230. The water inlet structure 230 is used to connect to an external water source.

[0083] Among them, the water inlet structure 230 is connected to the connecting portion 212 and is in communication with the inner cavity.

[0084] In some embodiments, the extending direction of the water inlet structure 230 is the same as the extending direction of the housing 210. In this way, the dimension of the pre - purification module 200 for a water heater along the extending direction of the water inlet structure 230 is the sum of the dimensions of the water inlet structure 230 and a part of the housing 210, or only the dimension of the housing 210. After the pre - purification module 200 for a water heater is installed, the dimension along the extending direction of the water inlet structure 230 is smaller, which is beneficial to the hidden installation of the pre - purification module 200 for a water heater.

[0085] Moreover, the extending direction of the water inlet structure 230 is the same as the extending direction of the housing 210, which is beneficial to the connection of the pipeline for connecting to an external water source.

[0086] In some embodiments, the water heater pre-purification module 200 includes a water outlet structure 240. The water outlet structure 240 is used to connect to the water inlet end 110 of the water heater body 100.

[0087] Wherein, the water outlet structure 240 is connected to the connecting portion 212 and is in communication with the inner cavity.

[0088] In some embodiments, the extending direction of the water outlet structure 240 is the same as the first direction. In this way, the dimension of the water heater pre-purification module 200 along the extending direction of the water outlet structure 240 is the sum of the length of the water outlet structure 240 and the dimension of a part of the housing 210. After the water heater pre-purification module 200 is installed, the dimension along the extending direction of the water outlet structure 240 is small, which is beneficial to the hidden installation of the water heater pre-purification module.

[0089] In some embodiments, the first direction forms an angle with the extending direction of the housing 210. In this way, the extending direction of the water outlet structure 240 forms an angle with the extending direction of the water inlet structure 230. In this way, compared with the case where the extending direction of the water outlet structure 240 is parallel to the extending direction of the water inlet structure 230, this embodiment facilitates the connection of the water outlet structure 240 to the water inlet end 110 of the water heater body 100 and facilitates the connection of the water inlet structure 230 to an external water source.

[0090] It should be noted that the first direction may be the direction shown by the Y-axis in the figure, and the extending direction of the housing 210 may be the direction shown by the X-axis.

[0091] In some embodiments of the present application, the extending direction of the water outlet structure 240 is perpendicular to the extending direction of the water inlet structure 230. In this way, it is beneficial to meet the daily use habits of users, facilitates the connection of the water outlet structure 240 to the water inlet end 110 of the water heater body 100, and facilitates the connection of the water inlet structure 230 to an external water source.

[0092] In some embodiments, the angle between the extending direction of the water outlet structure 240 and the extending direction of the water inlet structure 230 is greater than 90 degrees.

[0093] In some embodiments, the angle between the extending direction of the water outlet structure 240 and the extending direction of the water inlet structure 230 is less than 90 degrees.

In this way, it is convenient to disassemble and assemble the body 211 and replace the filter assembly 220.

[0095] Specifically, the bottle body 2111 and the bottle cap 2112 can be connected by threads.

[0096] In some embodiments, an operation part is provided at one end of the bottle body 2111 facing away from the bottle cap 2112, facilitating the installation and disassembly of the bottle body 2111 and the bottle cap 2112.

[0104] In some embodiments, the water inlet structure 230 is located on the side of the connecting part 212 facing the bottle body 2111, and the extending direction of the water inlet structure 230 is consistent with the axial direction of the main body 211. In this way, it is beneficial that the dimension of the water heater pre - purification module along the extending direction of the water inlet structure 230 is only the dimension of the housing 210.

[0105] In some embodiments of the present application, the water outlet structure 240 and the water inlet structure 230 are located on different sides of the connecting part 212, and the extending direction of the water outlet structure 240 is consistent with the radial direction of the main body 211.

[0134] Exemplarily, the nut 242 can be made of copper.

[0135] In some embodiments, the water heater pre-purification module 200 includes a third seal 290, and the third seal 290 is located between the nut fixing member 241 and the inner wall of the connecting column, thereby improving the sealing effect.

[0139] See Figure 8 、 Figures 10 to 12 As shown in

[0140] In some embodiments of the present application, the main body 211 is configured with a first cavity, the filtering assembly 220 is located in the first cavity, and an inlet water cavity 2113 and an outlet water cavity 2114 are formed between the outer wall of the filtering assembly 220 and the inner wall of the main body 211 and are separated from each other.

[0141] In some embodiments, the extending direction of the filtering assembly 220 is consistent with the extending direction of the main body 211.

[0142] In some embodiments, the pre-purification module 200 for a water heater includes a fourth seal 2100.

[0143] Among them, the fourth seal 2100 is located between the filtering assembly 220 and the inner wall of the main body 211, thereby improving the sealing effect. One side of the fourth seal 2100 is the inlet water cavity 2113, and the other side is the outlet water cavity 2114.

[0144] Exemplarily, the material of the fourth seal 2100 can be rubber.

[0145] In some embodiments, the inlet structure 230 is communicated with the second cavity 2121, the second cavity 2121 is communicated with the inlet water cavity 2113, the outlet structure 240 is communicated with the third cavity 2122, and the third cavity 2122 is communicated with the outlet water cavity 2114.

[0146] Specifically, the external water source enters the filtering assembly 220 through the inlet structure 230, the second cavity 2121 and the inlet water cavity 2113, and the filtered water enters the water heater main body 100 through the outlet water cavity 2114, the third cavity 2122 and the outlet structure 240.

[0147] In some embodiments of the present application, the filtering assembly 220 includes a cartridge 221.

[0148] Among them, the cartridge 221 is configured with a fourth cavity 2211, and filter media is arranged in the fourth cavity 2211.

[0149] Among them, the number of the fourth cavities 2211 can be one, two or more.

[0150] In some embodiments, the cartridge 221 is configured with at least two interconnected fourth cavities 2211, and filter media is disposed in the fourth cavities 2211.

[0151] It can be understood that different filter media can be respectively placed in different fourth cavities 2211, and the water flow can sequentially pass through the different filter media in different fourth cavities 2211, and the purification effects of different substances are in sequence to achieve a better effect. For example, it can first pass through calcium sulfite for removing residual chlorine, and then pass through a scale inhibitor material, such as FOF (Full Organic Formula) scale inhibitor. Because there will be residues of calcium sulfite after removing residual chlorine, and the residual calcium ions will form scale. Then passing through the scale inhibitor material FOF later can prevent the calcium and magnesium ions in the original water and the residual calcium ions of calcium sulfite from forming scale at the same time. If the flowing sequence is reversed or the two materials are mixed together, the effect will become worse.

[0152] It should be noted that other filter media can also be respectively placed in the two fourth cavities 2211. Moreover, one fourth cavity 2211 can contain one type of filter media or multiple types of filter media.

[0153] In some embodiments, a magnet can be disposed in the fourth cavity 2211 for adsorbing rust in the water.

[0154] In some embodiments, at least two fourth cavities 2211 are arranged along the extending direction of the cartridge 221. In this way, when the water flow passes through the filter assembly, the cross-sectional area of the water flow channel is relatively large, and it is not easy to reduce the water flow rate.

[0155] Specifically, at least two fourth cavities 2211 are arranged along the axial direction of the cartridge 221.

[0156] In some embodiments, the fourth cavity 2211 at one end along the extending direction of the cartridge 221 is communicated with the water inlet cavity 2113, and the fourth cavity 2211 at the other end is communicated with the water outlet cavity 2114. In this way, when the size of the cartridge 221 is fixed, the flow path of the water in the cartridge 221 is relatively long, which is beneficial to improving the filtering effect.

[0157] In some embodiments of the present application, the cartridge 221 includes a cartridge body 2212.

[0158] Exemplarily, the cartridge body 2212 can be cylindrical.

[0159] In some embodiments, the barrel body 2212 can be made of a plastic material with relatively high strength, such as POM (polyformaldehyde), and can withstand relatively high water pressure.

[0160] In some embodiments of the present application, the barrel 221 includes at least one partition 2213. The partition 2213 is used to cooperate with the barrel body 2212 to form different fourth cavities 2211.

[0161] Wherein, at least one partition 2213 is located inside the barrel body 2212 to divide the inside of the barrel body 2212 into at least two fourth cavities 2211.

[0162] Wherein, the shape of the partition 2213 can match the shape of the barrel body 2212. For example, if the inner cavity of the barrel body 2212 is cylindrical, the shape of the partition 2213 can be circular.

[0163] It can be understood that the partition 2213 can be integrally provided with the barrel body 2212. Alternatively, the partition 2213 can be separately provided from the barrel body 2212 and then assembled. For example, the partition 2213 and the barrel body 2212 can be detachably connected, facilitating the replacement of the filter media.

[0164] In some embodiments, a communication port is provided on the partition 2213, and the size of the communication port is smaller than the size of the filter media. In this way, the filter media is not easily passed through the communication port, effectively avoiding the mixing of different filter media.

[0165] Wherein, the number of the communication ports can be one, two or more.

[0166] In some embodiments of the present application, the barrel body 2212 is configured with a water inlet 2212a, and the water inlet 2212a communicates the water inlet cavity 2113 with one of the fourth cavities 2211. The water inlet 2212a is close to the end of the barrel along the extending direction.

[0167] The barrel body 2212 is configured with a water outlet 2212b, and the water outlet 2212b communicates the water outlet cavity 2114 with another fourth cavity 2211.

[0168] In this way, when the size of the barrel body 2212 is fixed, water sequentially passes through all the fourth cavities 2211 in the barrel, which is beneficial to improving the filtration effect.

[0169] In some embodiments, the number of the water inlets 2212a can be multiple, and the multiple water inlets 2212a communicate with the same fourth cavity 2211.

[0170] It should be noted that the number and size of the water inlets 2212a are set according to requirements (such as water flow rate).

[0171] In some embodiments, the number of the water outlets 2212b can be multiple, and the multiple water outlets 2212b communicate with the same fourth cavity 2211.

[0172] In some embodiments, the size of the water outlet 2212b can be smaller than the size of the filter media, so as to effectively prevent the filter media from flowing out.

[0173] In some embodiments, within the region between the water inlet 2212a and the water outlet 2212b, a plurality of blind holes are formed in the cartridge body 2212. The blind holes do not communicate with the fourth cavity 2211, and the blind holes can play a role in weight reduction.

[0174] In some embodiments of the present application, one end of the cartridge body 2212 in the extending direction is provided with an opening. The cartridge 221 includes a first sealing cover 2214, and the first sealing cover 2214 is used to seal the opening at one end of the cartridge body 2212 in the extending direction.

[0175] Wherein, the first sealing cover 2214 is detachably connected to one end of the cartridge body 2212 in the extending direction. In this way, it is beneficial to replace the filter media in the cartridge body 2212.

[0176] In some embodiments, the first sealing cover 2214 can be made of a plastic material with relatively high strength, such as POM, and can withstand relatively high water pressure.

[0177] In some embodiments of the present application, in order to limit the position of the cartridge body 2212, a first limiting portion 2214a is formed at one end of the first sealing cover 2214 facing away from the cartridge body 2212, and a second limiting portion 213 matching the first limiting portion 2214a is formed on the inner wall of the housing 210. The first limiting portion 2214a is connected to the second limiting portion 213.

[0178] Specifically, one of the first limiting portion 2214a and the second limiting portion 213 can be a limiting protrusion, and the other can be a limiting groove.

[0179] In some embodiments of the present application, the other end of the cartridge body 2212 in the extending direction is provided with an opening. The cartridge 221 includes a second sealing cover 2215, and the second sealing cover 2215 is used to seal the opening at the other end of the cartridge body 2212 in the extending direction.

[0180] Wherein, the second sealing cover 2215 is detachably connected to the other end of the cartridge body 2212 in the extending direction. In this way, it is beneficial to replace the filter media in the cartridge body 2212.

[0181] In some embodiments, the second sealing cover 2215 can be made of a plastic material with relatively high strength, such as POM, and can withstand relatively high water pressure.

[0182] In some embodiments of the present application, in order to limit the position of the barrel body 2212, a third limiting portion 2215a is configured at one end of the second sealing cover 2215 facing away from the barrel body 2212, and a fourth limiting portion 214 matching the third limiting portion 2215a is configured on the inner wall of the housing 210. The third limiting portion 2215a is connected to the fourth limiting portion 214.

[0183] Specifically, one of the third limiting portion 2215a and the fourth limiting portion 214 may be a limiting protrusion, and the other may be a limiting groove.

[0184] It should be noted that, in order to improve universality, the structures of the second sealing cover 2215 and the first sealing cover 2214 may be the same.

[0185] In some embodiments of the present application, the filtering assembly 220 includes a filter element 222. The filter element 222 is located in the water inlet chamber 2113 and covers the water inlet 2212a.

[0186] It can be understood that the filter element 222 can preliminarily filter water and improve the water purification effect. Moreover, by providing the filter element 222 which covers the water inlet 2212a, it effectively prevents the filter media from leaking out through the water inlet 2212a.

[0187] Specifically, the filter element 222 may be a filter net.

[0188] In some embodiments, the filter element 222 may be a silver-plated filter net, which plays an antibacterial role.

[0189] In some embodiments, the material of the filter element 222 may be stainless steel.
