Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a kitchen faucet with a heating function. Background Technology

[0002] In residential hot water supply systems, when there is a long pipe between the water heater and the water terminal (such as a kitchen faucet), significant water stagnation occurs during the hot water delivery process. Specifically, after the user turns on the hot water faucet, it takes about 15-30 seconds (depending on the pipe length and diameter) for the room-temperature water that has been stagnant in the pipe to be drained before the effective hot water heated by the water heater can reach the outlet. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a kitchen faucet with a heating function.

[0004] The technical solution of this utility model is implemented as follows:

[0005] This utility model provides a kitchen faucet with a heating function, wherein a cold water pipe and a hot water pipe are installed inside the kitchen faucet, and the kitchen faucet also contains:

[0006] A heating water pipe includes an inlet section, a spiral heating section, and an outlet section. The inlet section enters the kitchen faucet from the bottom and connects to the spiral heating section. The spiral heating section extends spirally toward the bottom of the kitchen faucet and connects to the outlet section. The outlet section is connected to the water valve of the kitchen faucet.

[0007] A heater, installed inside the kitchen faucet, the heater including a spiral heating element;

[0008] The spiral heating tube and the spiral heating section form a double spiral structure;

[0009] The double helix structure is a double helix structure that is coaxial with each other, has the same helical direction, and has its helical loops embedded in the pitch space of the other.

[0010] The water outlet section passes through the spiral cavity of the double spiral structure from the bottom of the spiral heating section and extends upward to connect with the water valve of the kitchen faucet.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following:

[0012] By installing a heater with a heating function inside the kitchen faucet, specifically, the heater's spiral heating element and the spiral heating portion of the water pipe form a double spiral structure, effectively utilizing the height space of the kitchen faucet to increase the contact area between the spiral heating element and the spiral heating portion. During the heating process of the spiral heating element, the temperature of the spiral heating portion increases, and heat exchange occurs between the two, thereby heating the water in the water pipe. The outlet extends upwards from the bottom of the spiral heating portion through the spiral cavity of the double spiral structure, connecting to the water valve of the kitchen faucet. In this design, the hot water heated by the spiral heating portion flows upwards. It is worth noting that the inlet and outlet are relatively close. This design allows for heat exchange between the inlet and outlet after the water has been heated by the spiral heating element, thus preheating the water. Therefore, after the first round of heating in the spiral heating portion, the temperature of the water entering the spiral heating portion in the second round is affected by the temperature of the water already heated in the first round, thereby increasing the temperature of the water entering the spiral heating portion and increasing heating efficiency.

[0037] A kitchen faucet with heating function, wherein a cold water pipe 11 and a hot water pipe 12 are installed inside the kitchen faucet 10, and further wherein the kitchen faucet 10 also has:

[0038] The heating water pipe 13 specifically includes an inlet section 131, a spiral heating section 132, and an outlet section 133. The inlet section 131 enters the kitchen faucet 10 from the bottom and connects to the spiral heating section 132. The spiral heating section 132 extends spirally towards the bottom of the kitchen faucet 10 and connects to the outlet section 133. The outlet section 133 is connected to the water valve 15 of the kitchen faucet 10. The spiral heating section 132 and the inlet section 131 are connected to each other by threads. The spiral heating section 132 has external threads, and the inner wall of the inlet section 131 has internal threads that are compatible with the external threads. During installation, the inlet section 131 is screwed onto the spiral heating section 132 through the cooperation of the internal and external threads.

[0039] A heater 14 is further installed inside the kitchen faucet 10. The heater 14 includes a spiral heating tube 141, a circuit board 142 and a power cord 1421.

[0040] Specifically, the circuit board 142 is vertically installed inside the kitchen faucet 10, and the two ends of the spiral heating tube 141 are detachably installed on the surface of the circuit board 142; the power cord 1421 is connected to the bottom of the circuit board 142 and extends out of the bottom of the kitchen faucet 10. The end of the power cord 1421 away from the circuit board 142 has a power plug. When installing the kitchen faucet, the power plug needs to be connected to the power source so that the circuit board 142 can supply power to the spiral heating tube 141 for heating.

[0041] Furthermore, the spiral heating tube 141 and the spiral heating section 132 constitute a double-helix structure; specifically, the double-helix structure is a double-helix structure in which the spiral coils are coaxial, have the same direction of rotation, and are embedded in each other's pitch space. Please refer to [the relevant documentation / reference]. Figure 2 , Figure 3 and Figure 4 As shown, the installation method of this double helix structure is as follows:

[0042] First, the water outlet section 133 is separated from the spiral heating section 132, such as... Figure 12 As shown. Then, one end of the spiral heating tube 141 is inserted into the pitch space opening at the bottom of the spiral heating section 132. The position of this opening can be referenced... Figure 12 The black arrow in the center indicates this. Next, rotate the spiral heating tube 141, causing it to spiral upwards along the axial direction of the spiral heating section 132 until it reaches the top of the spiral heating section 132, as shown. Figure 15 As shown. Next, connect both ends of the spiral heating tube 141 to the circuit board 142. Then screw the water inlet section onto the circuit board using internal and external threads, as shown. Figure 17As shown, this completes the installation of the heater 14 and the heating water pipe 13. This design makes full use of the height space of the kitchen faucet 10 to increase the contact area between the spiral heating tube 141 and the spiral heating section 132. During the heating process of the spiral heating tube 141, the temperature of the spiral heating section 132 is increased, and heat exchange occurs between the two, thereby heating the water in the heating water pipe 13.

[0043] Then, the water outlet section 133 passes through the spiral cavity of the double spiral structure from the bottom of the spiral heating section 132, extends upward and connects to the water valve 15 of the kitchen faucet 10, as shown below. Figure 17 As shown, in this design, the hot water heated by the spiral heating section 132 will flow from bottom to top. It is worth noting that the inlet section 131 and the outlet section 133 are relatively close. Figure 7 The spacing between the inlet section 131 and the outlet section 133 shown is designed so that after the water flows through the spiral heating section for heating, the inlet section 131 and the outlet section 133 can exchange heat for preheating. Thus, after the spiral heating section 132 has undergone the first round of heating, the water temperature entering from the inlet section 131 in the second round will be affected by the water temperature of the water that has already been heated in the first round, thereby increasing the water temperature entering the spiral heating section 132 from the inlet section 131 and increasing the heating efficiency.

[0044] Furthermore, a heat insulation layer 16 is installed on the inner wall of the part of the kitchen faucet 10 corresponding to the spiral heating tube 141, which can reduce the situation where the outer wall temperature of the kitchen faucet 10 is too high due to the spiral heating tube 141.

[0045] As a further improvement to the above structure:

[0046] Water valve 15 includes:

[0047] The valve body 151 is installed on the kitchen faucet 10. The rear end of the valve body 151 has three connection holes 1511, which are respectively connected to the outlet section 133 of the cold water pipe 11, the hot water pipe 12, and the heating water pipe 13. The valve body 151 also has a water outlet 1512.

[0048] The valve core 152 is rotatably installed inside the valve body 151. The valve core 152 has an annular water outlet groove 1521 along its outer periphery. The valve core 152 also has a water inlet channel 1522, which is connected to the water outlet groove 1521.

[0049] By rotating the valve core 152, the opening of the water inlet channel 1522 can be connected to the cold water pipe 11, the hot water pipe 12 or the water outlet section 133, and can also be further pressed against the inner wall of the valve body 151.

[0050] When the opening of the water inlet channel 1522 is pressed against the inner wall of the valve body 151, the water inlet channel 1522 is blocked, so the kitchen faucet 10 is in the closed state.

[0051] When the opening of the water inlet channel 1522 is connected to the cold water pipe 11, the water in the cold water pipe 11 enters the water outlet tank 1521 through the water inlet channel 1522 and flows in the water outlet tank 1521 until it flows out from the water outlet 1512. At this time, the kitchen faucet 10 turns on the cold water mode.

[0052] When the opening of the water inlet channel 1522 is connected to the hot water pipe 12, the water in the hot water pipe 12 enters the water outlet tank 1521 through the water inlet channel 1522, flows in the water outlet tank 1521 until it flows out from the water outlet 1512, at which time the kitchen faucet 10 turns on the hot water mode.

[0053] When the opening of the water inlet channel 1522 is connected to the water outlet section 133, the heated water in the heating water pipe 13 enters the water outlet tank 1521 through the water inlet channel 1522 and flows in the water outlet tank 1521 until it flows out from the water outlet 1512. At this time, the kitchen faucet 10 turns on the mode of dispensing heated water.

[0054] Based on the further improvement of the above structure: the valve core 152 further has a blocking part 1523. When the opening of the water inlet channel 1522 abuts against the inner wall of the valve body 151, the blocking part 1523 reaches the position of the outlet 1512 and blocks the outlet 1512. In this way, the outlet 1512 can be blocked immediately without waiting for the water in the outlet tank 1521 to drain out.

[0055] The water valve 15 further includes a rotating handle 153, which is mounted on the front end of the valve core 152 and is located outside the kitchen faucet 10, thereby adjusting the mode of the faucet.

[0056] As a further improvement to the above structure, a sealing ring 1524 is also installed at the opening of the water inlet channel 1522 of the valve core 152, which can effectively prevent the water flow of the cold water pipe 11, hot water pipe 12 and heating water pipe 13 from flowing through the inner wall between the valve core 152 and the valve body 151.

[0057] It should be noted that the spiral heating section 132 and the water outlet section 133 are integrally formed structures, and both are made of copper. Copper has good thermal conductivity and can fully exchange heat.

[0058] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0059] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
