Description

Technical Field

[0001] The present invention relates to the technical field of water heaters, and more specifically, to a front-end water purification water heater. Background Art

[0002] A water heater refers to a device that raises the temperature of cold water to hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc. Electric water heaters can be divided into three types according to the heating power: storage type (also known as volumetric or heat storage type), instant type, and fast heating type (also known as semi-storage type).

[0003] However, when the current electric water heater is installed, the tap water is directly connected to the water inlet pipe of the water heater. When the water is supplied, the tap water directly enters the interior of the water heater. No filtering mechanism is installed at the front section of the water heater inlet. After the impurities in the water enter the interior of the water heater, a large amount of scale is easily generated, which not only affects the heating time but also easily damages the heating parts; the mixing valve at the bottom of the water heater is connected to the water inlet pipe and the water outlet pipe through nuts. When taking a bath, the valve on the mixing valve needs to be turned. When turning or pressing, a circumferential force is generated on the nut, and the nut on the mixing valve is easily loosened or the sealing ring is easily worn, resulting in water leakage; when using the water heater to take a bath, some users are used to hanging towels and clothes on the connecting pipe of the mixing valve. Some wet towels are heavy, and long-term placement will also cause the nut at the mixing valve to loosen and leak water; when cleaning the interior of the water heater, the drain port needs to be opened. The drain port is just a hole. After opening, the water inside the water heater directly drains out. No supporting disassembly and diversion components are provided, and the sewage cannot be discharged reasonably, polluting the ground. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a front-end water purification water heater.

[0007] Specifically, the fixing mechanism further includes rubber pads. Rubber pads are bonded to the upper surfaces of the two fixing plates.

[0008] Specifically, the water supply mechanism includes a left pipe and a pressure relief valve. The bottom of the water heater body is threadedly connected with a left pipe and a pressure relief valve. The bottom of the pressure relief valve is threadedly connected with a right pipe. A mixing valve is provided between the left pipe and the right pipe with an L-shaped cross-section. The two ends of the mixing valve are threadedly connected with the left pipe and the right pipe through nuts. A sealing cover is threadedly connected to the left pipe. A connecting column is fixedly connected to the right pipe. A water outlet pipe is provided at the bottom of the mixing valve. The two plugs are inserted into the two nuts.

[0009] Specifically, the filtering mechanism includes a filter. A filter is inserted into the interiors of the two fixing rings. An ultrafiltration membrane filter element is provided inside the filter. End caps are threadedly connected to both ends of the filter. Connecting pipes are threadedly connected to the ends of both end caps. One of the connecting pipes is threadedly connected with the connecting column on the right pipe.

[0010] Specifically, the filtering mechanism further includes two retaining rings. Retaining rings are fixedly connected to the inner walls of the two end caps. Filter meshes are threadedly connected to both retaining rings. A cavity is formed between the filter mesh and the end cap.

[0011] Specifically, the suspension mechanism includes two groups of limiting rings. Two limiting rings are fixedly connected to each of the two outer shells. A rotating ring rotatably connected to the outer shell is provided between the two limiting rings. Rotating rods are fixedly connected to both rotating rings. Mounting rods are threadedly connected to both rotating rods. Support rods are fixedly connected to the ends of both mounting rods.

[0012] Specifically, the suspension mechanism further includes hanging grooves. Hanging grooves are equidistantly formed on both support rods. The angle between the two support rods and the mounting rod is 150 degrees, and the two support rods are cross-set. The two support rods respectively abut against the outer shell on the opposite side.

[0013] Specifically, the sewage discharge mechanism includes a diversion pipe and a sealing plug. The bottom of the water heater body is fixedly connected with a diversion pipe. A sealing plug is threadedly connected to the diversion pipe. The interior of the sealing plug is in a cylindrical structure and the exterior is in a hollow hexagonal prism structure.

[0014] Specifically, the sewage discharge mechanism further includes two side plates. Two arc-shaped side plates are fixedly connected to the bottom of the water heater body relatively.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) For a front-end water purification type water heater of the present invention, a fixing mechanism is provided on the water supply mechanism. When installing the filtering mechanism, the filter can be inserted into the inside of the two fixing rings. Insert the two plugs onto the two nuts. Ensure that the outer shell is horizontal and then rotate the inner rod inside the outer shell. Rotate the inner rod to move towards the wall. After the fixing plate abuts against the wall, the installation of the fixing mechanism is completed. On the one hand, the setting of the plugs can support the filter, facilitating the quick installation of the filter. On the other hand, the cooperation between the plugs and the fixing plate can limit the nuts on the mixing valve, and it can avoid the rotation between the nuts and the left pipe and the right pipe when the mixing valve switch is turned, resulting in wear and loosening at the connection and causing water leakage.

[0017] (2) For a front-end water purification type water heater of the present invention, hanging mechanisms are provided on both outer shells. When installing the outer shell and the inner rod, the two mounting rods and the rotating rod can be disassembled. After the outer shell and the inner rod are installed on the wall, then threadedly connect the two mounting rods and the rotating rod. And the two mounting rods are arranged in a crosswise manner, and can abut against the outer shell on the opposite side. And the two staggeredly arranged support rods can hang hangers, towels or clothes on the hanging grooves on their surfaces, avoiding hanging on the mixing valve and causing loosening and water leakage at the connection.

[0018] (3) For a front-end water purification type water heater of the present invention, the sewage discharge mechanism is detachably connected to the bottom of the water heater body. When it is necessary to discharge the sewage inside the water heater body, the top ring can be inserted between the two side plates. Note that the two hanging plates are arranged crosswise with the side plates. Then rotate the top ring by ninety degrees to make the hanging plates rotate to the slots on the inner walls of the side plates, completing the hanging of the funnel. Further, one end of the drain pipe is inserted into the inside of a water receiving container or a floor drain. Further, push the sleeve to make the sleeve sleeved on the outer wall of the sealing plug. Rotate the sleeve to disassemble the sealing plug. Reset the sleeve to separate the sealing plug from the diversion pipe. At this time, the water inside the water heater flows into the funnel and then is discharged into the floor drain through the drain pipe, avoiding large-area pollution of the ground.

[0019] (4) A front-end water purification type water heater according to the present invention, wherein a filtering mechanism is inserted on a fixing mechanism, one connecting pipe of the filtering mechanism is connected to the water inlet, and the other connecting pipe is connected to a connecting column. The water inlet enters the interior of the ultrafiltration membrane filter element through an end cap and is discharged from the other end cap. And sodium hexa metaphosphate can be placed between the end cap and the filter screen to soften the water. The ultrafiltration membrane filter element filters the water entering the interior of the water heater body, preventing impurities from entering the water heater and forming a large amount of water scale, which affects the heating of the water.

Detailed implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] As Figures 1 - 11As shown in the figure, a front-end water purification type water heater according to the present invention includes a water heater body 1 and a water supply mechanism 2 installed on the water heater body 1. A fixing mechanism 4 is detachably connected to the water supply mechanism 2. A filtering mechanism 3 is installed on the fixing mechanism 4. The filtering mechanism 3 is connected to the water supply mechanism 2. A hanging mechanism 5 is provided on the fixing mechanism 4. A sewage discharging mechanism 6 is installed on the water heater body 1. The fixing mechanism 4 includes two plugs 408. Two plugs 408 are inserted into the water supply mechanism 2. Two fixing rings 407 are fixedly connected to the two plugs 408. Fixed seats 406 opposite to the plugs 408 are fixedly connected to the two fixing rings 407. Plug rods 409 are inserted into the two fixed seats 406. Plug plates 405 are fixedly connected to the two groups of plug rods 409. Outer shells 401 are fixedly connected to the two plug plates 405. Inner rods 402 are threadedly connected to the interiors of the two outer shells 401. The fixing mechanism 4 further includes a fixing plate 403. Disk-shaped fixing plates 403 are fixedly connected to the ends of the two plug rods 409, and an H-shaped structure is formed between the two outer shells 401. The fixing mechanism 4 further includes rubber pads 404. Rubber pads 404 are bonded to the two fixing plates 403. After the filter 301 is installed on the water delivery pipeline of the water heater body 1, ensure that the tops of the two nuts 205 are in a horizontal position. Insert the two plugs 408 onto the two nuts 205. The plug 408 is equivalent to an open-ended wrench that can hold the nut 205. At this time, the fixed seat 406 is horizontal. Hold the filter 301. In order to facilitate the installation of the fixing ring 407, the filter 301 can be disconnected from the water source at this time. Insert the plug rods 409 on the two plug plates 405 into the holes on the two fixed seats 406. At this time, the outer shell 401 and the fixing ring 407 form an integral body. Rotate the inner rod 402 to screw it out from the interior of the outer shell 401. Rotate the fixing plate 403 until it abuts against the wall surface. The rubber pad 404 increases the friction force. On the one hand, it realizes the support for the filter 301, facilitating the quick installation of the filter 301 without drilling holes in the wall surface. On the other hand, it realizes that the plug 408 and the fixing plate 403 are in a horizontal position to support and limit the nut 205, avoiding the rotation of the nut 205 and the wear and leakage at the connection when pressing the switch of the mixing valve 204.

[0035] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the water supply mechanism 2 includes a left pipeline 201 and a pressure relief valve 202. The bottom of the water heater body 1 is threadedly connected with the left pipeline 201 and the pressure relief valve 202. The bottom of the pressure relief valve 202 is threadedly connected with a right pipeline 208. A mixing valve 204 is provided between the left pipeline 201 with an L-shaped cross-section and the right pipeline 208. Both ends of the mixing valve 204 are threadedly connected with the left pipeline 201 and the right pipeline 208 through nuts 205. A sealing cover 203 is threadedly connected to the left pipeline 201. A connecting column 207 is fixedly connected to the right pipeline 208. A water outlet pipe 206 is provided at the bottom of the mixing valve 204. The two plugs 408 are inserted into the two nuts 205; the filtering mechanism 3 includes a filter 301. The filter 301 is inserted into the interior of the two fixing rings 407. An ultrafiltration membrane filter element 304 is provided inside the filter 301. End caps 302 are threadedly connected to both ends of the filter 301. Connecting pipes 303 are threadedly connected to the ends of both end caps 302. One of the connecting pipes 303 is threadedly connected with the connecting column 207 on the right pipeline 208; the filtering mechanism 3 further includes two retaining rings 305. Retaining rings 305 are fixedly connected to the inner walls of both end caps 302. Filter screens 306 are threadedly connected to both retaining rings 305. A cavity for containing sodium hexa metaphosphate is formed between the filter screen 306 and the end cap 302;When installing the water heater body 1, fix the water heater body 1 on the wall with expansion screws. Connect the mixing valve 204 to the left pipe 201 and the right pipe 208 through the nuts 205 at both ends. Connect the pressure relief valve 202 to the top of the right pipe 208. Then thread-connect the left pipe 201 and the pressure relief valve 202 to the bottom installation port of the water heater body 1, completing the installation of the mixing valve 204. Further, connect the sealing cover 203 to the opening on the left pipe 201 to prevent water leakage. Insert the filter 301 into the inside of the two fixing rings 407. At this time, the filter 301 can be in a temporarily suspended state. Thread-connect one of the connecting pipes 303 to the connecting post 207 on the right pipe 208, and connect the other connecting pipe 303 to the water supply pipe. At this time, water can pass through the end cap 302 and the ultrafiltration membrane filter element 304. The impurities in the water can be softened by the sodium hexa metaphosphate placed between the end cap 302 and the filter screen 306. The impurities in the water are filtered by the ultrafiltration membrane filter element 304 to prevent impurities from entering the inside of the water heater body 1 and forming a large amount of scale, which affects the heating of water. When it is necessary to replace the ultrafiltration membrane filter element 304, the end cap 302 can be disassembled, and the ultrafiltration membrane filter element 304 can be pulled out for replacement or cleaning. After the end cap 302 is disassembled, the end cap 302 can be shaken. If there is an object collision between the filter screen 306 and the end cap 302, it means that the sodium hexa metaphosphate has not been completely dissolved. If there is no sound, the filter screen 306 can be disassembled by holding the handle on the filter screen 306. Add sodium hexa metaphosphate to the inside of the end cap 302 and then thread-connect the filter screen 306 to the retaining ring 305. Place the new ultrafiltration membrane filter element 304 into the inside of the filter 301, and thread-connect the end cap 302 to the filter 301. After the water heater body 1 boils water, the temperature of the discharged water can be controlled by the switch of the mixing valve 204.;

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the suspension mechanism 5 includes two groups of limit rings 505. Two limit rings 505 are fixedly connected to each of the two outer shells 401. A swivel ring 506 rotatably connected to the outer shell 401 is provided between the two limit rings 505. A rotating rod 504 is fixedly connected to each of the two swivel rings 506. A mounting rod 503 is threadedly connected to each of the two rotating rods 504. A support rod 501 is fixedly connected to the end of each of the two mounting rods 503. The suspension mechanism 5 further includes a hanging groove 502. Hanging grooves 502 are equidistantly formed on the two support rods 501. The included angle between the two support rods 501 and the mounting rod 503 is 150 degrees, and the two support rods 501 are cross - arranged. The two support rods 501 are respectively in contact with the outer shell 401 on the opposite side. When installing the outer shell 401, the mounting rod 503 can be separated from the rotating rod 504 to avoid the support rod 501 affecting the installation of the outer shell 401. After the outer shell 401 is completely installed, the two mounting rods 503 are threadedly connected to the rotating rod 504. At this time, the two support rods 501 are arranged in an interleaved manner. Hangers, towels, etc. can be hung on the hanging grooves 502 on the support rods 501, which can prevent hangers and towels from hanging at the mixing valve 204 during bathing, causing loosening of the joint and water leakage, and make full use of the space at the bottom of the water heater body 1. If there is no habit of hanging towels during bathing, the support rod 501 can be directly separated from the rotating rod 504 to avoid occupying space.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 9 , Figure 10 and Figure 11As shown, the sewage discharge mechanism 6 includes a diversion pipe 607 and a sealing plug 608. The bottom of the water heater body 1 is fixedly connected to the diversion pipe 607, and the sealing plug 608 is threadedly connected to the diversion pipe 607. The inside of the sealing plug 608 is of a cylindrical structure, and the outside is of a hollow hexagonal prism structure. The sewage discharge mechanism 6 further includes two side plates 601. Two arc-shaped side plates 601 are relatively fixedly connected to the bottom of the water heater body 1. A top ring 602 is provided between the two side plates 601. The top ring 602 is located at the bottom of the diversion pipe 607. Two suspension plates 610 that are slidably connected to the inner walls of the side plates 601 are relatively fixedly connected to the outer wall of the top ring 602. A funnel 603 is fixedly connected to the bottom of the top ring 602. A bottom ring 604 is fixedly connected to the bottom of the funnel 603. A rotating ring 609 is rotatably connected to the inside of the bottom ring 604. A sleeve 605 of a hollow hexagonal structure is fixedly connected to the inside of the rotating ring 609. The six sides of the sleeve 605 are all open. A drain pipe 606 is fixedly connected to the bottom of the sleeve 605. The top end of the sleeve 605 is inserted into the outer wall of the sealing plug 608. When it is necessary to clean the sewage inside the water heater body 1, hold the funnel 603 and insert the top ring 602 between the two side plates 601. At this time, note that the suspension plate 610 is misaligned with the inner wall of the side plate 601. After aligning the suspension plate 610 with the chute on the inner wall of the side plate 601, rotate the funnel 603 by ninety degrees to rotate the suspension plate 610 into the inside of the side plate 601. At this time, the funnel 603 is suspended. Connect the drain pipe 606 to the inside of the floor drain, push the sleeve 605 towards the sealing plug 608 to insert the sleeve 605 into the sealing plug 608. Hold the sleeve 605 and rotate it to loosen and remove the sealing plug 608. After pulling the sleeve 605, the sealing plug 608 is opened, and the sewage flows from the holes on the side wall of the sleeve 605 into the inside of the funnel 603 and finally discharges from the drain pipe 606, avoiding a large amount of sewage splashing onto the ground and causing large-area pollution in the morning. After finishing, the funnel 603 can be rotated to separate the suspension plate 610 from the side plate 601, and it can be stored for use next time.

[0038] When the present invention is in use, first, when installing the water heater body 1, the water heater body 1 is fixed to the wall surface by expansion screws. The mixing valve 204 is connected to the left pipe 201 and the right pipe 208 through the nuts 205 at both ends. The pressure relief valve 202 is connected to the top of the right pipe 208. Then, the left pipe 201 and the pressure relief valve 202 are threadedly connected to the bottom installation port of the water heater body 1, completing the installation of the mixing valve 204. Further, the sealing cover 203 is connected to the opening on the left pipe 201 to prevent water leakage. The filter 301 is inserted into the interior of the two fixing rings 407. At this time, the filter 301 can be in a temporarily suspended state. One connecting pipe 303 is threadedly connected to the connecting post 207 on the right pipe 208, and the other connecting pipe 303 is connected to the water supply pipe. At this time, water can pass through the end cover 302 and the ultrafiltration membrane filter element 304. The impurities in the water can be softened by the sodium hexa metaphosphate placed between the end cover 302 and the filter screen 306. The impurities in the water are filtered by the ultrafiltration membrane filter element 304, preventing impurities from entering the interior of the water heater body 1 to form a large amount of scale and affecting the heating of water. When it is necessary to replace the ultrafiltration membrane filter element 304, the end cover 302 can be disassembled, and the ultrafiltration membrane filter element 304 can be pulled out for replacement or cleaning. After the end cover 302 is disassembled, the end cover 302 can be shaken. If there is an object collision between the filter screen 306 and the end cover 302, it means that the sodium hexa metaphosphate has not been completely dissolved. If there is no sound, the handle on the filter screen 306 can be held to disassemble it. Sodium hexa metaphosphate can be added to the interior of the end cover 302, and then the filter screen 306 is threadedly connected to the retaining ring 305. The new ultrafiltration membrane filter element 304 is placed into the interior of the filter 301, and the end cover 302 is threadedly connected to the filter 301. After the water heater body 1 heats the water, the temperature of the discharged water can be controlled by the switch of the mixing valve 204;

[0039] Then, after the filter 301 is installed on the delivery pipeline of the water heater body 1, ensure that the tops of the two nuts 205 are in a horizontal position. Insert the two plugs 408 into the two nuts 205. The plug 408 is equivalent to an open-end wrench and can hold the nut 205. At this time, the fixing seat 406 is in a horizontal position. Hold the filter 301 (in order to facilitate the installation of the fixing ring 407, the filter 301 can be disconnected from the water source at this time). Insert the insertion rods 409 on the two insertion plates 405 into the holes on the two fixing seats 406. At this time, the housing 401 and the fixing ring 407 are formed into a whole. Rotate the inner rod 402 to screw it out from the interior of the housing 401. Rotate the fixing plate 403 until it abuts against the wall surface. The rubber pad 404 increases the friction force. On the one hand, it realizes the support of the filter 301, facilitating the rapid installation of the filter 301 without drilling holes in the wall. On the other hand, it realizes that the plug 408 and the fixing plate 403 are in a horizontal position to support and limit the nut 205, preventing the nut 205 from rotating when pressing the switch of the mixing valve 204 and causing wear and water leakage at the connection;

[0040] Next, when installing the outer shell 401, the installation rod 503 can be separated from the rotating rod 504 to avoid the support rod 501 affecting the installation of the outer shell 401. After the outer shell 401 is completely installed, the two installation rods 503 and the rotating rod 504 are threadedly connected. At this time, the two support rods 501 are arranged staggeredly. Hangers, towels, etc. can be hung on the hanging grooves 502 on the support rods 501, which can prevent the hangers and towels from hanging at the mixing valve 204 during bathing, causing the joints to loosen and leak water, and make full use of the space at the bottom of the water heater body 1. If you don't have the habit of hanging towels during bathing, you can directly separate the support rod 501 from the rotating rod 504 to avoid occupying space;

[0041] Finally, when it is necessary to clean the sewage inside the water heater body 1, hold the funnel 603 and insert the top ring 602 between the two side plates 601. At this time, note that the hanging plate 610 is misaligned with the pipeline on the inner wall of the side plate 601. After aligning the hanging plate 610 with the chute on the inner wall of the side plate 601, rotate the funnel 603 by 90 degrees to rotate the hanging plate 610 into the inside of the side plate 601. At this time, the funnel 603 is suspended. Connect the drain pipe 606 to the inside of the floor drain, push the sleeve 605 towards the sealing plug 608 to insert the sleeve 605 into the sealing plug 608. Hold the sleeve 605 and rotate it to loosen and remove the sealing plug 608. Pull the sleeve 605 to open the sealing plug 608. The sewage flows from the holes on the side wall of the sleeve 605 into the inside of the funnel 603 and finally drains out from the drain pipe 606, avoiding a large amount of sewage splashing onto the ground and causing large-area pollution. After finishing, the funnel 603 can be rotated to separate the hanging plate 610 from the side plate 601, and it can be stored for use next time.
