Description

When in the off position, the water at the water inlet end is blocked from flowing into the inner tank; 2. When in the cold water position, the heating system is not turned on and cold water is released; 3. When in the hot water position, the heating system is turned on and hot water is released.

[0005] Under normal water pressure conditions, the water cavity in the inner tank body is full and there will be no dry-burning problem; however, when the water is cut off, due to insufficient water pressure, if the user operates it incorrectly - the valve core is not screwed into place (in the transition position), the water in the inner cavity will flow back out; then even when the water pressure is normal, the water in the inner cavity will dry up and the heating system will be turned on, which will easily cause dry-burning problems.

[0060] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0061] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0062] like Figure 3 and Figure 4 As shown in the prior art, water in the heating chamber 201 of a conventional vertical electric water faucet will flow out from the valve core in an unexpected situation, causing the static water level of the heating chamber 201 to be low, and even causing the heating component 30 to be completely exposed. If the valve core gear is still in the heating port docking state at this time, the heating component 30 will continue to work, which will cause unexpected dangers. In order to solve this technical problem, the utility model proposes the following technical solutions:

[0063] like Figure 1 and Figure 2 As shown, the vertical electric hot water faucet 100 with a check water structure includes an outer shell 10, an inner tank 20, a heating component 30 and a valve core component 40; the inner tank 20 is arranged in the outer shell 10, and the heating component 30 is arranged in a heating chamber 201 in the inner tank 20. Among them, the inner tank 20 is made of high-strength and corrosion-resistant materials, and its internal structure is reasonably designed, which can effectively accommodate the heating component 30 and ensure the stable operation of the heating chamber 201.

[0064] The heating assembly 30 uses an efficient and energy-saving heating element, and its longitudinal layout is reasonable, which can evenly heat the water in the inner tank 20, improve the heating efficiency, and shorten the heating time. The valve core assembly 40 has reliable sealing performance and stable water flow control ability, which can ensure smooth water flow and prevent water leakage and seepage.

[0065] In addition, a water inlet 21 is provided at the lower end of the inner liner 20, and a water outlet 22 is provided at the upper end of the inner liner 20, so as to achieve smooth inflow and outflow of water while ensuring the stability and uniformity of the water flow.

[0066] Preferably, the water outlet 22 adopts a streamlined design, which can effectively reduce the resistance of the water flow, increase the flow rate and flow rate of the water flow, and ensure that the user can get enough hot water supply when using it. At the same time, the position and angle of the water outlet 22 are optimized, so that the direction and uniformity of the water outlet are effectively controlled, and the splashing and unevenness of the water flow are avoided. A special diversion structure may be used around the water inlet 21, so that the water flow can enter the inner tank 20 in a more uniform and stable manner. This can be achieved by setting a guide plate, annular guide groove or guide hole, etc., which effectively reduces the turbulence and resistance of the water flow and ensures the guidance and stability of the water flow.

[0067] Furthermore, the inner pot 20 is provided with a water inlet channel 23, and the valve core of the valve core assembly 40 is connected with the water inlet 21 through the water inlet channel 23. In order to achieve the technical purpose of the utility model, a water check structure 50 is provided in the heating chamber 201 in the inner pot 20, and the water check structure 50 can prevent the water in the heating chamber 201 from flowing back to the water inlet channel 23 through the valve core.

[0068] The water-check structure 50 includes a first vertical channel 51 and a second vertical channel 52 which are parallel to each other. The lower end of the first vertical channel 51 is connected to the valve core, the lower end of the second vertical channel 52 is connected to the heating chamber 201, and the upper end of the first vertical channel 51 is connected to the upper end of the second vertical channel 52. The highest point of the first vertical channel 51 is connected to the second vertical channel 52, and the connection point is higher than the static water level of the heating chamber 201 in the water leakage state, so as to prevent water from flowing back from the heating chamber 201. Then, it is ensured that there is always water in the heating chamber 201 to cover the heating component 30, so as to avoid the accidental empty burning of the heating component 30 and avoid accidents.

[0069] In the present technical solution, the inner tank 20 includes a main body b1, a water outlet b2 and a water inlet pipe assembly b3. The upper end of the main body b1 is provided with an upper opening b11, and the lower end of the main body b1 is provided with a lower opening b12.

[0070] The water outlet b2 includes an upper end b21 and a water outlet b22, and the water inlet pipe assembly b3 includes a lower end b31 and a water inlet pipe b32. The upper end b21 is installed on the upper opening b11, and the lower end b31 is installed on the lower opening b12.

[0071] The upper and lower openings of the main body b1 have comparable cross sections and correspond to each other in the longitudinal direction, thus maintaining a balanced state of the water flow. When in use, the turbulence and eddy current of the water flow can be effectively reduced, ensuring the stability and uniformity of the water flow, and reducing the backflow or dead corner inside the inner tank 20.

[0072] The technical means of the inner liner 20 has a similar cross-section between the upper and lower openings, so that the overall structure of the inner liner 20 is more balanced and stable and is less likely to deform or vibrate.

[0073] The water inlet pipe b32 of the water inlet pipe assembly b3 and the water outlet b22 of the water outlet head b2 have a small distance difference in the lateral dimension, which helps to reduce the energy loss of water flow during the inlet and outlet process, improves the efficiency and flow rate of the water flow, further optimizes the water flow control performance of the product, reduces the pressure loss and noise of the water flow, improves the use efficiency and comfort of the product, and enhances the competitiveness of the product.

[0074] More specifically, the first vertical channel 51 is closely attached to the inner wall of the inner tank 20; the wall of the first vertical channel 51 is integrally formed with the shell of the inner tank 20, ensuring the close combination of the check water structure and the inner tank, thereby effectively preventing the overflow or leakage of water in the inner tank. The water flow turning member 60 is plugged into the upper end of the first vertical channel member 51 to form a second vertical channel 52.

[0075] like Figure 8 As shown, the first vertical channel 51 is surrounded by a U-shaped wall p, which extends along the height direction of the inner wall of the inner liner 20 . The opening of the U-shaped wall p faces the inner wall of the inner liner 20 and is integrally formed with the shell of the inner liner 20 .

[0076] The first vertical channel is surrounded by a U-shaped wall p, and the U-shaped wall p is integrally formed with the shell of the inner liner 20; the water flow turning member 60 is connected to the U-shaped wall p. The design of this structure directly forms a channel in the shell of the inner liner p, avoiding the risks of joints and leakage that may be caused by traditional assembly methods. The design of the U-shaped wall p also takes into account water flow dynamics, and its shape helps to guide water flow smoothly through the channel.

[0077] Furthermore, the integral formation of the U-shaped wall p and the inner tank 20, combined with the stable connection of the water flow turning member 60, together constitutes a highly stable non-return water operation mechanism. This technical means can show extremely high reliability when subjected to water pressure and temperature changes.

[0078] The water flow turning member 60 is a key component connecting the first vertical channel 51 and the second vertical channel 52, and has an important function. The water flow turning member 60 includes a plug-in pipe section 61 and a drainage pipe section 62, and the plug-in pipe section 61 and the drainage pipe section 62 are connected through a connecting pipe section 63, which ensures the smooth transmission of the water flow and enables the water flow between the first and second vertical channels to be effectively connected, ensuring that the water flow will not be blocked or broken. The highest connection point is located at the connecting pipe section 63, which can not only avoid the problem of empty burning of the heating component 30, but also enable the water flow to maintain the best flow state when entering and exiting the channel.

[0079] Furthermore, the inner cavity of the drainage pipe section 62 forms at least a part of the second vertical channel 52; preferably, the inner cavity of the drainage pipe section 62 is the entire second vertical channel 52; the space can be utilized to the maximum extent, and the channel width and flow capacity of water flow transmission are increased. The stability and continuity of the water flow during the flow process can be ensured. No longer restricted by the division of the channel, the water flow can flow freely in the entire channel, avoiding the problem of water flow blockage or unevenness caused by poor channel connection.

[0080] During installation, the plug-in pipe section 61 is inserted into the upper end of the first vertical channel 51 to connect the first and second vertical channels. Through the insertion of the plug-in pipe section 61, the first vertical channel 51 and the second vertical channel 52 are completely connected, ensuring smooth flow between the two channels. In addition, this plug-in method avoids additional connectors or pipes, simplifying the path of water flow.

[0081] Preferably, the wall surfaces of the connecting pipe section 63 and the drainage pipe section 62 facing the inner wall of the liner 20 are arc-shaped walls, so that the connecting pipe section 63 and the drainage pipe section 62 can fit the inner wall of the liner 20. Minimize the gap at the connection and optimize the component distribution pattern.

[0082] In addition, the connecting pipe section 63 maintains a consistent lateral height. Such a design can reduce the stress concentration or structural instability problems that may be caused by the height difference of the pipe sections, improve the structural strength and vibration resistance of the product, and ensure the safety and reliability of the product.

[0083] The length of the plug-in pipe section 61 is smaller than that of the drainage pipe section 62, so that the water flow bending member 60 has a 7-shaped structure; the water flow bending member 60 with this structure can make the water flow experience more sufficient guidance and control when turning, can more accurately control the direction and speed of the water flow, and reduce the turbulence and resistance of the water flow at the turn, which helps to improve the control performance of the water flow.

[0084] In addition, the vertical extension path of the wall of the first vertical channel 51 is consistent with the vertical distribution path of the plug-in pipe section 61, which helps to reduce the flow resistance loss generated by the water flow at the bend and is conducive to enhancing the structural stability of the channel. In this way, the pressure fluctuation and oscillation inside the channel can be reduced, and the stability and reliability of the channel can be improved.

[0085] The inner wall surface of the first vertical channel 51 fits with the inner wall surface of the drainage tube section 62. The fitting of the inner walls ensures a seamless connection between the first vertical channel 51 and the drainage tube section 62, and optimizes the compact layout of the components in the inner cavity.

[0086] More preferably, the inner wall surface of the first vertical channel 51 and the inner wall surface of the drainage pipe section 62 are both inclined, maintaining the same inclination amplitude and width. Such a design makes the component layout of the entire waterproof reflux structure more compact and reasonable, which helps to improve the stability and reliability of the environment of the inner cavity 201. By optimizing the component layout, full utilization of the internal space is ensured.

[0087] In addition, it should be noted that there are three ports on the valve core, including a water inlet port, a hot start port and a water outlet port. The water inlet port is connected to the water inlet channel 23, and the water outlet port is connected to the lower end of the first vertical channel 51.

[0088] When the user turns on the faucet, cold water enters the valve core through the water inlet port and then flows to the heating chamber 201 for heating. The hot start port is connected to the hot start switch to receive the signal from the hot start switch. The hot start switch senses the change in water temperature, and the hot start port of the valve core controls the operation of the hot start switch to control the heating component 30 in the heating chamber 201 to heat. When the water temperature reaches the set value, hot water is supplied.
