Description

Technical Field

[0001] The present invention relates to the technical field of kitchen water circuits, and particularly to a shared water circuit system for kitchen appliances. Background Art

[0002] With the continuous improvement of people's living standards, the pursuit of material conditions by consumers is also increasing. In family kitchens, various types of kitchen utensils are arranged, such as steam ovens, dishwashers, and range hoods. These kitchen utensils are installed in different positions in the kitchen, and dishwashers, steam ovens, and range hoods with steam washing functions all require water. This requires arranging different water supply pipelines according to different devices.

[0003] Currently, most of the existing kitchen water supply pipelines are laid according to the kitchen layout positions in the early stage of decoration. When supplying water to kitchen appliances such as dishwashers and steam ovens later, it is necessary to install independent water supply pipelines, resulting in a messy layout of the water supply pipelines for kitchen appliances. If the water supply pipelines of different devices are integrated into one water pipeline, the water use of different kitchen appliances is easily affected by changes in water pressure. Secondly, the tap water entering the household contains too many minerals for existing kitchen appliance equipment and must be softened before use. This requires installing a water softening device. However, it is not easy to share the water supply pipeline of one water softening device when installing the water softening device for the messy pipelines. If different devices need to install water softening devices, the cost will be too high. Therefore, in view of the problem of the messy layout of the existing water supply pipelines for kitchen appliances, multiple water supply pipelines cannot share one water softening device, and the cost increases due to the need to install water softening devices for different devices. At the same time, the subsequent maintenance of multiple pipelines is also relatively cumbersome and inconvenient. Therefore, the present application provides a shared water circuit system for kitchen appliances to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a shared water circuit system for kitchen appliances to solve the problems of the messy layout of the existing kitchen appliance water circuits, the integration and use of multiple water supply pipelines, which easily cause the water use of kitchen appliances to be affected by water pressure, and multiple water pipelines cannot share one water softening device, resulting in an increase in cost due to the need to install water softening devices for different devices.

[0017] In the above solution, through the provided outer frame, the water softening device and different water pipelines can be integrated inside. Subsequently, through the softening control valve, it is connected to the water inlet module, and the household tap water can be directly injected into the water softening device for softening. The softened water flows through the softening control valve and then into the main control valve, and then enters the flow splitting module through the main control valve. According to different usage requirements, it is injected into the connected connection module through the three outlets opened at the lower part of the flow splitting module, and is temporarily stored after being processed in the direct drinking water storage module, the through tank, and the cooking water storage module. Since the extraction module is interconnected with the direct drinking water storage module, the through tank, and the cooking water storage module through the docking module, when using water subsequently, it will be more convenient to extract and use through the respective interconnected extraction modules. Compared with the traditional independent multiple water supply pipelines, the integrated shared water pipeline can share one water softening device, saving the cost of softening equipment. At the same time, according to the three different water storage structures installed inside, it supplies water for different kitchen water uses, which not only realizes the independence of each kitchen appliance's water use, but also reduces the problem of being affected by water pressure between them.

[0018] By setting up a water level monitor, since it is installed at the upper end of the direct drinking water storage module and the cooking water storage module, and the lower end of the water level monitor extends into the interiors of the direct drinking water storage module and the cooking water storage module, the liquid levels inside the direct drinking water storage module and the cooking water storage module are monitored in real time. When the liquid levels inside the direct drinking water storage module and the cooking water storage module decrease to a preset height, the water level monitor will transmit a signal to the intelligent valve in the flow splitting module, and the intelligent valve is set to open the water supply of the left L pipe and the right L pipe, so as to timely supply water to the interiors of the direct drinking water storage module and the cooking water storage module, ensuring that the liquid levels inside the direct drinking water storage module and the cooking water storage module always remain above the safety line, guaranteeing subsequent water usage requirements, and improving the convenience of use.

[0019] By setting up an inlet module, a flow splitting module, and a connection module, the three modules are all installed in a segmented structure. When there are faults in the equipment and pipelines inside the outer frame and the inner frame, according to the location of the fault, segmented disassembly can be directly carried out, and the faulty part can be directly replaced as a whole, improving the convenience of fault repair.

[0041] As Figures 1 to 12As shown, an embodiment of the present invention provides a shared waterway system for kitchen appliances, including an outer frame 1. Below the inside of the outer frame 1, there is an inner frame 2. On the right side of the upper end of the inner frame 2, there is a water softening device 3. On the left side of the water softening device 3, there is a softening salt tank 4. On the top of the water softening device 3, there is a softening control valve 5. On the right side of the softening control valve 5, there is a water inlet module 6 connected. On the left side of the softening control valve 5, there is a main control valve 7 connected. At the lower end of the main control valve 7, there is a flow splitting module 8 connected. At the lower end of the flow splitting module 8, there is a connection module 9 connected. Below the connection module 9, there are a direct drinking water storage module 10, a direct-through tank 11, and a cooking water storage module 12 connected. The direct drinking water storage module 10, the direct-through tank 11, and the cooking water storage module 12 are arranged horizontally. On the left side of the upper ends of the direct drinking water storage module 10 and the cooking water storage module 12, there is a water level monitor 13. On the left side of the direct drinking water storage module 10, the direct-through tank 11, and the cooking water storage module 12, there is a docking module 14 connected. Below the left side of the outer end of the outer frame 1, there is an extraction module 15. At the upper end of the extraction module 15, there is an anti-backflow module 16 connected.

[0042] The inner frame 2 is embedded in the outer frame 1, and the installation method between the two is a pull-out type. The bottom of the base of the water softening device 3 and the softening salt tank 4 are both hollow structures. The inner diameters of the two hollow structures are adapted to the outer diameters of the bottom pad 204 set at the upper end of the inner frame 2. The water softening device 3 is sleeved and installed on the upper end of the inner frame 2. The water softening device 3 consists of a lower tank body and an upper cover, and the two can be disassembled. The softening salt tank 4 is also sleeved and installed on the upper end of the inner frame 2. A salt outlet is opened above the front end of the softening salt tank 4. The softening control The control valve 5 is threadedly installed at the upper end of the water softening device 3, and the four sides of the lower end of the softening control valve 5 are provided with connection ports, wherein the left connection port is the water inlet, and the water inlet and the water inlet module 6 are mutually threadedly connected, the right connection port is the water outlet, and the water outlet and the main valve 7 are mutually connected, and the front connection port is the salt suction port, and the salt suction port and the salt outlet of the softening salt tank 4 are connected through a hose, and the front side is the sewage outlet. Secondly, both the water softening device 3 and the softening salt tank 4 are existing mature and well-known technologies, so they are not discussed in this article. Too much elaboration, the main valve 7 and the diverter module 8 are connected to each other by threads, the diverter module 8 and the connection module 9 are connected by a quick connector 806, the connection module 9 and the direct drinking water storage module 10, the straight tank 11 and the cooking water storage module 12 are connected to each other by threads, the water level monitor 13 and the direct drinking water storage module 10 and the cooking water storage module 12 are connected to each other by threads, and the connection ends of the water level monitor 13 and the direct drinking water storage module 10 and the cooking water storage module 12 are sealed, the water level monitor 13 It is electrically connected to the intelligent valve 805 in the diversion module 8 and the electric switch 152 in the extraction module 15. The docking module 14 is threadedly connected to the direct drinking water storage module 10, the straight-through tank 11 and the cooking water storage module 12. The docking module 14 is threadedly installed at the lower left side of the outer end of the outer frame 1. The extraction module 15 is reinforced at the lower left side of the outer wall of the outer frame 1 by bolts. The extraction module 15 and the docking module 14 are interconnected, and the anti-backflow module 16 and the extraction module 15 are quickly connected in a snap-on manner.

[0043] Through the provided outer frame 1, the water softening device 3 and different water pipelines can be integrated inside. Subsequently, it is connected to the water inlet module 6 through the softening control valve 5, and the incoming tap water can be directly injected into the water softening device 3 for softening. The softened water flows through the softening control valve 5 and is injected into the main pipe valve 7, and then enters the shunt module 8 through the main pipe valve 7. According to different usage requirements, it is injected into the connected connection module 9 through three outlets opened at the lower part of the shunt module 8, and is temporarily stored after being processed in the direct drinking water storage module 10, the through tank 11, and the cooking water storage module 12. Since the extraction module 15 is interconnected with the direct drinking water storage module 10, the through tank 11, and the cooking water storage module 12 through the docking module 14, when using water subsequently, it will be more convenient to pump water through the extraction module 15 that is respectively connected to different kitchen appliances. Compared with the traditional independent multiple water supply pipelines, the integrated shared water pipeline can share one water softening device 3, saving the cost of softening equipment. At the same time, according to the three water storage structures with different properties installed inside, water is supplied to different kitchen appliances, which not only realizes the independence of each kitchen appliance's water use but also reduces the problem of being affected by water pressure between them. Moreover, by setting the water level monitor 13, since it is installed at the upper ends of the direct drinking water storage module 10 and the cooking water storage module 12, and the lower end of the water level monitor 13 extends into the interiors of the direct drinking water storage module 10 and the cooking water storage module 12, the liquid levels inside the direct drinking water storage module 10 and the cooking water storage module 12 are monitored in real time. When the liquid levels inside the direct drinking water storage module 10 and the cooking water storage module 12 decrease to the preset height, the water level monitor 13 will transmit a signal to the intelligent valve 805 and the electric switch 152 in the shunt module 8, causing the electric switch 152 to shut down the water pump 153, and opening the water supply of the left L pipe 803 and the right L pipe 804 through the set intelligent valve 805, so as to timely supply water to the interiors of the direct drinking water storage module 10 and the cooking water storage module 12, ensuring that the liquid levels inside the direct drinking water storage module 10 and the cooking water storage module 12 always remain on the safety line, guaranteeing subsequent water use requirements, and improving the convenience of use. Secondly, through the provided anti-backflow module 16, during use, as long as the water flow is pumped out from the direct drinking water storage module 10, the through tank 11, and the cooking water storage module 12 and then used, the pumped water flow will be blocked, and the situation of backwater causing water source pollution inside the direct drinking water storage module 10, the through tank 11, and the cooking water storage module 12 will not occur.

[0044] Such as Figures 1 to 6As shown in the figure, in this embodiment, the inner frame 2 includes a rectangular box 201, a clamping plate 202, a support column 203, a bottom pad 204, a pipe hole 205, a sealing groove 206, a front sealing plate 207 and a slider 208. A clamping plate 202 is provided above the rectangular box 201. Support columns 203 are threadedly installed on the front and rear sides of the lower end of the clamping plate 202. Bottom pads 204 are provided on the left and right sides of the upper end of the clamping plate 202. A pipe hole 205 is horizontally opened in the middle of the upper end of the clamping plate 202. Sealing grooves 206 are opened on the left and right sides of the outer end of the rectangular box 201. A front sealing plate 207 is provided at the front end of the rectangular box 201. Sliders 208 are horizontally distributed at the lower end of the rectangular box 201.

[0045] Two groups of threaded holes are horizontally opened on the front and rear sides of the upper end of the rectangular box 201 and the front and rear sides of the lower end of the clamping plate 202. Threaded heads that can move independently are provided at the upper and lower ends of the support column 203. The threaded heads at the upper and lower ends are adapted to the threaded grooves opened at the upper end of the rectangular box 201 and the lower end of the clamping plate 202. The bottom pad 204 is welded and installed at the upper end of the clamping plate 202. The size of the bottom pad 204 is adapted to the hollow structure opened under the lower bases of the water softening device 3 and the softening salt tank 4. Three pipe holes 205 are longitudinally distributed, and the spacing between the three is equal to the spacing of the water outlet positions below the shunt module 8. Six sealing grooves 206 are symmetrically distributed on the left and right. The front sealing plate 207 and the rectangular box 201 are reinforced by screws. Three sliders 208 are horizontally distributed, and the sliders 208 and the rectangular box 201 are of an integral structure.

[0046] By providing the rectangular box 201, the direct drinking water storage module 10, the through tank 11 and the cooking water storage module 12 can be installed in the temporal part. Moreover, the left and right sides of the direct drinking water storage module 10, the through tank 11 and the cooking water storage module 12 pass through the sealing grooves 206 to communicate with the connection module 9 and the docking module 14. The upper end structure of the connection module 9 passes through the pipe hole 205 to achieve segmented installation. Then, the clamping plate 202 is supported by the support column 203 and forms an integral structure with the rectangular box 201. By providing the front sealing plate 207, the front side of the rectangular box 201 is closed, so that the direct drinking water storage module 10, the through tank 11 and the cooking water storage module 12 are in a closed structure, preventing some insects or cockroaches from entering the interior. Subsequently, when maintenance and repair are required, the integral structure formed by the rectangular box 201 and the clamping plate 202 can be pulled out from the interior of the outer frame 1 through the handle in the middle of the front end of the front sealing plate 207 to achieve rapid maintenance and repair.

[0047] As Figures 1 to 3As shown in the figure, in this embodiment, the water inlet module 6 includes a pre-filter 601, a U-shaped pipe 602, a water inlet pipe 603, a quick connector 604, and a drain pipe 605. The left and right sides of the outer end of the pre-filter 601 are communicated with the U-shaped pipe 602. The front side of the left end of the U-shaped pipe 602 is communicated with the water inlet pipe 603. The front side of the right end of the U-shaped pipe 602 is communicated with the quick connector 604. The lower end of the pre-filter 601 is communicated with the drain pipe 605.

[0048] The pre-filter 601 is a mature and well-known technology in the art. Therefore, it will not be elaborated too much in this article. The U-shaped pipe 602 is connected to the left and right sides of the pre-filter 601 in a segmented threaded manner. The front end of the right side of the U-shaped pipe 602 is quickly connected to the water inlet pipe 603 in a snap-fit manner. The front end of the left side of the U-shaped pipe 602 is also quickly connected to the quick connector 604 in a snap-fit manner. The drain pipe 605 is threadedly installed at the lower end of the pre-filter 601.

[0049] By setting the U-shaped pipe 602, the water inlet pipe 603, and the quick connector 604, the segmented installation of the water inlet module 6 is realized, so that in case of pipeline damage caused by water pressure problems in the future, the damaged area can be quickly repaired and replaced. By installing the pre-filter 601, its main purpose is to filter large particulate impurities in the water before the tap water enters the water softening device 3, thereby protecting the backend equipment, reducing the subsequent purification burden, and ensuring the safety of domestic water.

[0050] As Figure 4 and Figure 5 shown in the figure, in this embodiment, the flow splitting module 8 includes a four-way valve 801, a middle vertical pipe 802, a left L-shaped pipe 803, a right L-shaped pipe 804, an intelligent valve 805, and a quick joint 806. The middle of the lower end of the four-way valve 801 is communicated with the middle vertical pipe 802. The left side of the outer end of the four-way valve 801 is provided with the left L-shaped pipe 803. The right side of the outer end of the four-way valve 801 is provided with the right L-shaped pipe 804. The middle parts of the left L-shaped pipe 803 and the right L-shaped pipe 804 are both communicated with the intelligent valve 805. The inner sides of the lower ends of the middle vertical pipe 802, the left L-shaped pipe 803, and the right L-shaped pipe 804 are provided with quick joints 806; the connection module 9 includes a vertical pipe 901, a threaded elbow 902, a horizontal pipe 903, and a side U-shaped pipe 904. The lower end of the vertical pipe 901 is communicated with the threaded elbow 902. The right end of the threaded elbow 902 is communicated with the horizontal pipe 903. The right end of the horizontal pipe 903 is communicated with the side U-shaped pipe 904.

[0051] The four-way valve 801 is threadedly connected to the middle vertical pipe 802, the left L-shaped pipe 803, and the right L-shaped pipe 804. Two intelligent valves 805 are symmetrically installed. The intelligent valves 805 are connected to the water level monitor 13 through wireless signals. Among them, the intelligent valve 805 is an existing and mature well-known technology. Therefore, it will not be elaborated too much in this text. They are respectively installed in the middle regions of the left L-shaped pipe 803 and the right L-shaped pipe 804. The contact ends of the two intelligent valves 805 with the left L-shaped pipe 803 and the right L-shaped pipe 804 are both butt-mounted. Three quick connectors 806 are symmetrically distributed and are installed on the inner sides of the lower ends of the middle vertical pipe 802, the left L-shaped pipe 803, and the right L-shaped pipe 804, and they are all hermetically welded and reinforced with each other. Buckle-type sleeves are installed at both the upper and lower ends of the vertical pipe 901 for quick connection with the middle vertical pipe 802, the left L-shaped pipe 803, the right L-shaped pipe 804, and the threaded elbow 902. The contact end between the lower right side of the threaded elbow 902 and the horizontal pipe 903 is connected in a threaded reinforcement manner. The right end of the horizontal pipe 903 is connected to the side U-shaped pipe 904 in a threaded reinforcement manner.

[0052] By setting the four-way valve 801 to communicate with the middle vertical pipe 802, the left L-shaped pipe 803, and the right L-shaped pipe 804, the tap water injected into the main pipe valve 7 can be diverted. Among them, the upper end of the middle vertical pipe 802 is directly connected to the four-way valve 801, and the lower end of the middle vertical pipe 802 is connected to the direct-through tank 11 through the connection module 9, mainly supplying kitchen equipment such as dishwashers, range hoods, or vegetable washing basins that have less demanding water quality requirements and relatively large water consumption. Therefore, a flow valve structure is not installed on the middle vertical pipe 802. Secondly, intelligent valves 805 are set between the left L-shaped pipe 803 and the right L-shaped pipe 804 and the four-way valve 801. At the same time, the lower ends of the left L-shaped pipe 803 and the right L-shaped pipe 804 are interconnected with the direct drinking water storage module 10 and the cooking water storage module 12 through the connection module 9, mainly supplying equipment such as steam ovens, coffee machines, water purifiers, and direct drinking machines that have higher water quality requirements, and the water consumption of these equipment is not very high. Through the integrated water inlet and the separate flow distribution water supply structure, it is convenient to supply water to different kitchen electrical equipment and achieve independent water supply to each other. And through the set vertical pipe 901, threaded elbow 902, horizontal pipe 903, and side U-shaped pipe 904, the segmented assembly structure among them can directly perform segmented disassembly according to the location where the fault occurs when the pipeline fails, and directly replace the faulty part as a whole, improving the convenience of fault repair.

[0053] Such as Figure 7 and Figure 8As shown in the figure, in this embodiment, the direct drinking water storage module 10 includes a direct drinking outer pipe 101, a direct drinking inner pipe 102, an overflow plate 103, a plug pipe 104, and a water suction pipe 105. The direct drinking inner pipe 102 is arranged inside the direct drinking outer pipe 101. The overflow plate 103 is arranged on the left side inside the direct drinking inner pipe 102. The plug pipes 104 are arranged at the left and right ends of the direct drinking inner pipe 102. The water suction pipe 105 is arranged on the left side inside the direct drinking inner pipe 102.

[0054] The direct drinking inner pipe 102 and the direct drinking outer pipe 101 are installed in a socket structure. And a semi-circular opening structure is opened on the left side of the upper end of the direct drinking inner pipe 102. The overflow plate 103 is embedded and installed on the inner side of the contact end between the left side inside the semi-circular opening structure and the right-side tubular structure of the direct drinking inner pipe 102. The overall height of the overflow plate 103 is slightly lower than the semi-circular opening structure opened on the left side of the upper end of the direct drinking inner pipe 102, which is convenient for the water flow to enter the left-side cavity inside the direct drinking inner pipe 102 for storage after being filtered inside the right-side tubular structure and passing over the overflow plate 103. There are two plug pipes 104 distributed on the left and right. The right plug pipe 104 has one more section than the left plug pipe 104 for installing an activated carbon adsorption structure inside. And the outer diameter of the left end of the plug pipe 104 is adapted to the inner diameter of the left-side tubular structure of the direct drinking inner pipe 102, and they are installed in a socket structure. The contact ends of the plug pipes 104 installed on the left and right sides with the direct drinking outer pipe 101 are sealed. The water suction pipe 105 is threadedly connected to the pipeline installed in the middle of the left plug pipe 104.

[0055] By arranging the direct drinking outer pipe 101, the direct drinking inner pipe 102, and the plug pipe 104, the three are installed in a socket structure with each other. When the softened tap water passes through the right plug pipe 104, the organic matters, abnormal colors, abnormal odors, and residual chlorine in the water flow are adsorbed by the activated carbon adsorption structure arranged inside the right plug pipe 104. When the overall liquid level of the water flow after adsorption is higher than the overflow plate 103, it will enter the left-side cavity inside the direct drinking inner pipe 102 for storage. Subsequently, during use, the stored water flow can be directly pumped out through the extraction module 15 that is interconnected by the left plug pipe 104 and the water suction pipe 105 for direct drinking. Since the devices directly connected to the direct drinking water storage module 10 include a water purifier and a direct drinking machine, and it can be directly drunk by people, therefore, the water flow after adsorption can improve the taste of the drinking water and protect the subsequent water purification equipment, and improve the overall quality of the drinking water.

[0056] Such as Figure 7 and Figure 9As shown in the figure, in this embodiment, the cooking water storage module 12 includes a cooking outer tube 121, a cooking inner tube 122, a connecting tube 123, a lining tube 124, an electric heating tube 125, and a heating power connection head 126. Inside the cooking outer tube 121, there is a cooking inner tube 122. Inside the right side of the cooking inner tube 122, there is a connecting tube 123. Inside the front end of the connecting tube 123, there is a lining tube 124. The outer side of the lining tube 124 is wrapped with an electric heating tube 125. In the middle of the upper end of the connecting tube 123, there is a heating power connection head 126.

[0057] Both the cooking inner tube 122 and the cooking outer tube 121 are of an integral tubular structure, and the outer diameter of the cooking inner tube 122 is adapted to the inner diameter of the cooking outer tube 121. The two are sleeved and installed. Moreover, through holes for installing the water level monitor 13 are provided on the left side of the upper ends of both. At the same time, a ring-shaped baffle is welded in the middle area inside the cooking inner tube 122. There are two connecting tubes 123 symmetrically distributed left and right, and both the left and right connecting tubes 123 are hermetically spliced with the cooking outer tube 121. The inner left end of the connecting tube 123 is sleeved and installed with a lining tube 124, and the right ends of the connecting tube 123 and the lining tube 124 are structurally connected. The overall length of the lining tube 124 is only half of that of the cooking inner tube 122, and the outer diameter of the left end of the lining tube 124 is adapted to the diameter of the ring-shaped baffle in the middle of the inner side of the cooking inner tube 122, and a sealing treatment is performed at the contact end between the two. The left end of the lining tube 124 is an open structure. After the lining tube 124 contacts the ring-shaped baffle inside the cooking inner tube 122, the right side area inside the cooking inner tube 122 and the lining tube 124 are sleeved and installed, and there is an annular gap in the sleeved installation area between the two. The electric heating tube 125 is conveniently installed inside the annular gap. The right side of the electric heating tube 125 extends into the connecting tube 123 and is electrically connected to the heating power connection head 126 installed in the middle of the upper end of the connecting tube 123.

[0058] After the cooking outer tube 121, the cooking inner tube 122, and the lining tube 124 are sleeved and installed, the electric heating tube 125 is installed in the annular gap between the cooking inner tube 122 and the lining tube 124. When water flows into the lining tube 124 through the connection module 9, the heating power connection head 126 supplies power to the electric heating tube 125 to preheat the water flow inside the lining tube 124. The cooking water storage module 12 is mainly connected to some devices such as a steam oven and a coffee machine. The water used is not for direct drinking but for further processing. The requirement for water quality is not as high as that of direct drinking water. After softening, it can be directly used. Moreover, by preheating the water flow, the temperature of the water flow can be increased, the heating time during processing of the equipment can be shortened, the waiting time can be reduced, and at the same time, the energy consumption and operating cost of the equipment can be reduced.

[0059] As Figures 1 to 10As shown, in this embodiment, the docking module 14 includes a conical block 141, a front pipe 142, a telescopic tube 143 and a threaded joint 144, the middle part of the front end of the conical block 141 is connected to the front pipe 142, the upper end of the front pipe 142 is connected to the telescopic tube 143, and the middle part of the rear end of the conical block 141 is provided with a threaded joint 144; the extraction module 15 includes a T-plate 151, an electric switch 152, a water pump 153 and a manual switch 154, the electric switch 152 is provided on the right side of the upper end of the T-plate 151, the water pump 153 is provided on the left side of the electric switch 152, and the upper end of the electric switch 152 is provided with a manual switch 154.

[0060] The docking module 14 is arranged in three groups in a transverse manner, the conical block 141, the front pipe 142 and the threaded joint 144, which are directly connected together by threaded installation. The upper and lower ends of the telescopic tube 143 are respectively connected to the front pipe 142 and the water pump 153. The middle part of the telescopic tube 143 can be bent, and the front end of the threaded joint 144 is connected to the direct drinking water storage module 10, the direct tank 11 and the cooking water storage module 12, so that the direct drinking water storage module 10, the direct tank 11 and the cooking water storage module 12 form a mutually connected conveying structure through the docking module 14 and the extraction module 15. , in disguise as an overall extension of the suction port below the water pump 153; the T-shaped plate 151 is a side-inverted installation structure, and screw holes are provided on the upper and lower sides of the left end of the T-shaped plate 151 for reinforcement with the outer frame 1. The electric switch 152 and the manual switch 154 are electrically connected to each other. At the same time, the electric switch 152 and the water level monitor 13 are connected in a line. The line of the manual switch 154 is connected to the power line of the water pump 153. The main purpose of the manual switch 154 is to shut down the water pump 153 when the electric switch 152 fails or needs subsequent maintenance.

[0061] By means of the electric switch 152, the water pump 153 can be controlled to be turned on or off so that the water pump 153 generates suction to draw water in the direct drinking water storage module 10, the straight tank 11 and the cooking water storage module 12 upward through the docking module 14, and then transport it upward through the water outlet of the water pump 153. The purpose of the entire docking module 14 structure is to extend the water suction port at the lower end of the water pump 153. In addition, the conical block 141, the front connecting pipe 142, the telescopic pipe 143 and the threaded joint 144 in the docking module 14 can all be segmented structures, which is convenient for early installation and subsequent disassembly.

[0062] like Figures 1 to 11As shown, in this embodiment, the anti-backflow module 16 includes a double-section pipe 161, a water-blocking pipe 162, a sleeve 163, a water-blocking rod 164, and a spring 165. The middle of the double-section pipe 161 is communicated with the water-blocking pipe 162. The left side of the outer end of the water-blocking pipe 162 is communicated with the sleeve 163. The water-blocking rod 164 is arranged inside the sleeve 163, and the spring 165 is sleeved on the left side of the outer end of the water-blocking rod 164.

[0063] The double-section pipe 161 is composed of two upper and lower pipes, and the two upper and lower double-section pipes 161 are threadedly communicated with the water-blocking pipe 162. The sleeve 163 is communicated with the water-blocking pipe 162. The contact ends between the water-blocking pipe 162 and the sleeve 163 are welded into an integral installation structure. The spring 165 is first sleeved and installed inside the sleeve 163, and then the water-blocking rod 164 is inserted into the inside of the sleeve 163. Among them, the rear end of the water-blocking rod 164 penetrates through the sleeve 163 and extends to the outside. At the same time, a sealing ring is sleeved on the outside of the front end of the water-blocking rod 164. The part of the front end of the water-blocking rod 164 inserted into the inside of the water-blocking pipe 162 is integrally in the shape of a round block, and the overall diameter of the round block is adapted to the diameter inside the water-blocking pipe 162. And the lower part of the round block is inclined, which is convenient for the water flow to squeeze the round block to shrink backward when it surges, and shrink into the inside of the sleeve 163 so that the inside of the water-blocking pipe 162 is unblocked. When the water flow is no longer conveyed upward subsequently, the contracted spring 165 pushes the front end structure of the water-blocking rod 164 to extend forward under the action of stress, so that the round block extends into the inside of the water-blocking pipe 162 to block the water flow inside the water-blocking pipe 162, preventing the water flow above from flowing back subsequently and causing water pollution inside the direct drinking water storage module 10, the direct-through tank 11, and the cooking water storage module 12.

[0064] The working principle of the technical solution provided by the present invention is as follows: By setting the outer frame 1, the water softening device 3 and different water pipelines can be integrated inside. Subsequently, through the softening control valve 5, it is connected to the water inlet module 6, and the household tap water can be directly injected into the water softening device 3 for softening. The softened water flows through the softening control valve 5 and is injected into the main pipe valve 7, and then enters the shunt module 8 through the main pipe valve 7. According to different usage requirements, it is injected into the connected connection module 9 through three outlets opened below the shunt module 8, and is temporarily stored after being processed in the direct drinking water storage module 10, the through tank 11, and the cooking water storage module 12. Since the extraction module 15 is interconnected with the direct drinking water storage module 10, the through tank 11, and the cooking water storage module 12 through the docking module 14, when using water subsequently, it will be more convenient to pump water through the extraction module 15 connected to different kitchen appliances respectively. Compared with the traditional independent multiple water supply pipelines, the integrated shared water pipeline can share one water softening device 3, saving the cost of softening equipment. At the same time, according to the three water storage structures with different properties installed inside, water is supplied to different kitchen appliances, which not only realizes the independence of each kitchen appliance's water use but also reduces the problem of being affected by water pressure between them. And, by setting the water level monitor 13, since it is installed at the upper ends of the direct drinking water storage module 10 and the cooking water storage module 12, and the lower end of the water level monitor 13 extends into the interiors of the direct drinking water storage module 10 and the cooking water storage module 12, the liquid levels inside the direct drinking water storage module 10 and the cooking water storage module 12 are monitored in real time. When the liquid levels inside the direct drinking water storage module 10 and the cooking water storage module 12 decrease to the preset height, the water level monitor 13 will transmit a signal to the intelligent valve 805 and the electric switch 152 in the shunt module 8, causing the electric switch 152 to shut down the water pump 153, and opening the water supply of the left L pipe 803 and the right L pipe 804 through the set intelligent valve 805, so as to timely supply water to the interiors of the direct drinking water storage module 10 and the cooking water storage module 12, ensuring that the liquid levels inside the direct drinking water storage module 10 and the cooking water storage module 12 always remain on the safety line, guaranteeing subsequent water use requirements, and improving the convenience of use. Secondly, by setting the anti-backflow module 16, during use, as long as the water flow is drawn out from the direct drinking water storage module 10, the through tank 11, and the cooking water storage module 12 and then used, it will block the drawn water flow, preventing the occurrence of backwater and the pollution of the water sources inside the direct drinking water storage module 10, the through tank 11, and the cooking water storage module 12; Secondly, by setting the water inlet module 6, the shunt module 8, and the connection module 9, the three modules are all installed in a segmented structure. When a failure occurs in the internal equipment and pipelines of the outer frame 1 and the inner frame 2, according to the location of the failure, it can be directly disassembled in segments, and the faulty part can be directly replaced as a whole, improving the convenience of fault repair.
