Description

Technical Field

[0001] The invention belongs to the technical field of heater equipment, and in particular relates to an instant hot water faucet. Background Art

[0002] Instant hot water faucets have the advantages of instant heating, small size, and no need for water tanks to store water. As people's living standards improve, they are becoming more and more popular among consumers.

[0003] Existing instant hot water faucets have the following problems: 1. When in use, you need to release cold water for several seconds before hot water can flow out of the spout, which cannot achieve "instant heating" in the true sense and causes a waste of water resources. 2. The water inlet end of the heating tube is connected to the water pump. If the water pump is turned off during use, the water flow to the heating tube will be pressurized and flow back. High-power heating tubes are prone to dry burning, causing damage to components. 3. After long-term use, a lot of dirt will accumulate on the spout of the instant hot water faucet, and the spout is easily plasticized, resulting in water plugging and reduced splash-proof effect. 4. Existing instant hot water faucets are one-piece and cannot be rotated left and right according to the customer's limit, which is inconvenient to use. Summary of the Invention

DETAILED DESCRIPTION

[0042] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0043] like Figure 1-Figure 2As shown, the hot water faucet comprises: an upper shell 1, on which a faucet device 2 and an adapter 3 connected to the faucet device 2 are provided, and the upper shell 1 has a connecting end 100; a lower shell 4, the interior of which is hollow, and the lower shell 4 has a first end 400 and a second end 401, and the first end 400 is rotatably connected to the connecting end 100; a connecting frame 5, on which a sealing member 6, a valve body device 7 and a heating device 8 connected to the valve body device 7 are provided, the connecting frame 5 is inserted into the lower shell 4 and the sealing member 6 abuts against the inner side wall of the second end 401, and the heating device 8 is connected to the adapter 3; a control panel 9, which is provided on the upper shell 1, and the control panel 9 is electrically connected to the heating device 8 and the valve body device 7. The control panel 9 is used to monitor the water flow rate, control the heating of the heating device 8 and the start and stop of the water outlet of the faucet.

[0044] When in use, the control panel 9 is pressed, and the valve body device 7 electrically connected to the control panel 9 is opened. The external water pump device increases pressure to send cold water through the valve body device 7 to the heating device 8. The cold water inside the heating device 8 is not backflow, and the heating device 8 quickly heats the cold water to achieve immediate boiling. The heated hot water is sent to the faucet device 2 through the adapter 3.

[0045] like Figure 3-Figure 4 As shown, preferably, the faucet device 2 includes: a faucet body 200, which is connected to the upper shell 1 by bolts, a cavity 201 is provided inside the faucet body 200, and a faucet water inlet end 202 and a faucet water outlet end 203 are provided on the faucet body 200, the faucet water inlet end 202 and the faucet water outlet end 203 are communicated with each other through the cavity 201, and the faucet water inlet end 202 is connected to the adapter 3; a locking cover 204, which is provided with a guide end 205, when the locking cover 204 is threadedly connected to the faucet body 200, the guide end 205 and the faucet water outlet end 203 enclose a cavity 206; a bubbler 207, which is movably arranged in the cavity 206.

[0046] The water inlet end 202 of the faucet is arranged on one side of the faucet body 200, and the water outlet end 203 of the faucet is arranged on the lower end surface of the faucet body 200. Hot water flows into the cavity 201 through the water inlet end 202 of the faucet, and then flows out from the bubbler 207 at the water outlet end 203 of the faucet. The bubbler 207 is made of food-grade 304 stainless steel, has good heat resistance, and will not plasticize. Hot water can filter out impurities when passing through the bubbler 207. The bubbler 207 is a kind of food-grade 304 stainless steel with good heat resistance and will not plasticize. 7 has the function of saving water and preventing splashing. The output hot water will not be sprayed out from the water nozzle under pressure, which reduces the impact force of the hot water. When the bubbler 207 needs to be replaced or cleaned, it is necessary to manually unscrew the locking cover 204 to take out the bubbler 207 and clean the dirt on the bubbler 207. After cleaning, the bubbler 207 is placed back on the guide end 205, and then the locking cover 204 is threadedly connected to the water outlet end 203 of the return nozzle. It is easy to clean and simple to disassemble and install.

[0047] Preferably, an exhaust pipe 208 is provided on the cavity 201 , and an exhaust hole 209 is provided on the locking cover 204 , and the exhaust pipe 208 is communicated with the exhaust hole 209 .

[0048] When hot water flows into the cavity 201 from the water inlet end 202 of the faucet, water vapor will be generated. If the faucet is not clear, the pressure inside the cavity 201 will be too high, and then splashing will occur when the hot water is output from the bubbler 207. The water vapor can be dissipated from the exhaust hole 209 through the exhaust pipe 208 to ensure that the hot water flows out of the bubbler 207 stably.

[0049] Preferably, the faucet body 200 has a cover plate 210 , and a baffle 211 is provided on the cover plate 210 . The baffle 211 is located between the exhaust pipe 208 and the water inlet end 202 of the faucet.

[0050] When hot water flows from the water inlet end 202 of the faucet to the cavity 201 , it also has a certain pressure cavity. The baffle 211 is set between the exhaust pipe 208 and the water inlet end 202 of the faucet to prevent the hot water from being over-pressurized and bursting out of the exhaust pipe 208 .

[0051] like Figure 5 As shown, preferably, the heating device 8 includes: a heating tube body 800, which is arranged on the connecting frame 5, a water flow channel is provided inside the heating tube body 800, the heating tube body 800 has a heating tube water inlet end 802 and a heating tube water outlet end 803 connected to the water flow channel, the heating tube water inlet end 802 is connected to the valve body device 7, and the heating tube water outlet end 803 is connected to the adapter 3; an electrode 804, which is sleeved on the heating tube body 800; and a protective shell 805, which is arranged on the heating tube body 800.

[0052] Cold water flows into the water flow channel through the valve body, and the electrode 804 drives the heating tube body 800 to achieve high-power rapid heating, achieving the effect of immediate heating and opening. The protective shell 805 can prevent external impurities from damaging the heating tube body 800 while also preventing heat loss, further accelerating the heating speed of cold water.

[0053] like Figure 2 or Figure 7 As shown, preferably, a limiting member 806 is detachably provided on the water outlet end 803 of the heating tube, one end of the adapter 3 is connected to the upper shell 1 by a bolt, and the other end of the adapter 3 is rotatably inserted into the limiting member 806, and a limiting block 807 is provided on the limiting member 806. A slide groove 101 and a stop block 102 connected to the slide groove 101 are provided in the upper shell 1, and the limiting block 807 is mounted on the slide groove 101. When the adapter 3 rotates relative to the limiting member 806, the stop block 102 can abut against the limiting block 807.

[0054] A chute 101 is provided within the upper housing 1, with a set of stops 102 positioned above it. A stopper 807 is positioned between these stops 102, allowing the upper housing 1 to rotate 120 degrees relative to the lower housing 4. The user can adjust the rotation to the left or right to meet customer needs. The stopper 807 has curved end faces on both sides, with notches formed between the curved end faces and the upper housing 1. The control panel 9 on the upper housing 1 is connected to the heating device 8 and valve assembly 7 in the lower housing 4 via wires, which can be electrically connected through the notches. When the upper housing 1 rotates left or right, the wires passing through the notches will not be pinched or severed by the rotation of the upper housing 1.

[0055] Preferably, a temperature control detection component 801 is provided at the water outlet end 803 of the heating pipe, and the temperature control detection component is connected to the adapter 3.

[0056] The temperature control detection component 801 can detect the temperature of the hot water output from the water outlet end 803 of the heating pipe, thereby realizing feedback through the control panel 9.

[0057] Preferably, a metal pipe 808 is provided on the water inlet end 802 of the heating pipe, a heat conducting plate 809 is clamped on the metal pipe 808, and a controller 810 is pressed against the heat conducting plate 809.

[0058] After the controller 810 is turned on, it generates a large amount of heat energy. The heat energy is transported to the metal pipe 808 through the heat conducting plate 809 to heat the cold water in the metal pipe 808 to realize heat energy recovery, thereby improving the heating efficiency of the heating tube body 800 and achieving the effect of instant heating and opening.

[0059] like Figure 6 As shown, preferably, the valve body device 7 includes: a one-way valve 700, which is arranged on the connecting frame 5, the one-way valve 700 has an inlet valve port 701 and an outlet valve port 702, and the inlet valve port 701 is connected to an external water pump; a water pipe 703, which is arranged on the outlet valve port 702, and the water pipe 703 is connected to the metal pipe 808; a flow detection component 704, which is arranged on the water pipe 703, and the flow detection component 704 is used to detect the water flow rate in the water pipe 703.

[0060] The external pump body delivers cold water from the water inlet valve port 701 to the water pipe 703. The one-way valve 700 can prevent the cold water from flowing back, ensuring that the heating tube body 800 will not dry-burn. A flow detection component 704 is provided in the water pipe 703. The flow detection component 704 can detect whether there is liquid in the water pipe 703 and provide feedback from the control panel 9 to further prevent the heating tube from dry-burning.

[0061] like Figure 8 As shown, preferably, the connecting frame 5 has a clamping portion 500 , a clamping member 501 is threadedly connected to the clamping portion 500 , and a through hole 502 is opened at the center of the clamping portion 500 , and the water inlet valve port 701 is located next to the through hole 502 .

[0062] The water pipe connected to the pump body passes through the through hole 502 and is then connected to the water inlet valve port 701, eliminating the need for line setting of the water pipe. The structure is compact, the volume is small, and it is suitable for more places.

[0063] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).
