Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a hot and cold water alternating washbasin. Background Technology

[0002] Currently, with the improvement of living standards, every household is starting to purchase and use washbasin products for decoration. Common washbasin faucets have only a single cold water outlet, which can affect the user experience in winter when the temperature is low in the north.

[0003] Therefore, it is necessary to design a washbasin with alternating hot and cold water. Utility Model Content

[0004] The technical problem this invention aims to solve is that common washbasin faucets have only a single cold water outlet, which can negatively impact the user experience, especially in winter when temperatures are low in northern regions.

[0005] To solve the above-mentioned technical problems, the present invention provides a hot and cold water alternating washbasin, the washbasin including a countertop wash basin, an under-counter cabinet installed below the countertop wash basin, a faucet installed above the countertop wash basin, an inlet pipe, an outlet pipe and a hot water assembly installed inside the under-counter cabinet, the inlet pipe being connected to the inlet of the hot water assembly, the outlet pipe including a hot water outlet pipe and a cold water outlet pipe, the cold water outlet pipe being directly connected to the inlet pipe, the hot water outlet pipe being connected to the outlet of the hot water assembly, both the hot water outlet pipe and the cold water outlet pipe being connected to the faucet, and switches being installed between the hot water outlet pipe, the cold water outlet pipe and the faucet respectively.

[0006] The hot water assembly includes a heating box, which is installed on the inner side wall of the under-counter cabinet, and a pair of electric heating coils are installed inside the heating box.

[0007] One of the electric heating coils has a straight pipe inside, and the other electric heating coil has a curved pipe inside. The top ends of the straight pipe and the curved pipe are connected to the hot water outlet pipe, and the bottom ends of the straight pipe and the curved pipe are connected to the water inlet pipe. A two-way switch is connected at the connection between the water inlet pipe and the straight pipe and the curved pipe.

[0008] A knob is installed on the outer wall of the under-counter cabinet, and one end of the knob is fixedly connected to the control shaft of the two-way switch.

[0009] The beneficial effects of this utility model are as follows:

[0010] Equipped with a hot water component, an electric heating coil, and a curved pipe, the system allows for easy operation. When only cold water is needed, simply turn on the switch connecting the cold water outlet pipe to dispense cold water from the faucet. When hot water is required, turn on the switch connecting the hot water outlet pipe; the cold water will be heated by the hot water component to dispense hot water from the faucet. To supply water to the straight pipe, the shorter length of the straight pipe within the electric heating coil results in warm water from the faucet. Conversely, when the curved pipe is longer within the electric heating coil, hot water will flow from the faucet. The dual-way switch can be easily controlled by turning the knob.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] Please see Figure 1-4The washbasin includes a countertop washbasin 1, an under-counter cabinet 2 installed below the countertop washbasin 1, and a faucet 3 installed above the countertop washbasin 1. The under-counter cabinet 2 contains an inlet pipe 4, an outlet pipe, and a hot water assembly. The inlet pipe 4 is connected to the inlet of the hot water assembly. The outlet pipe includes a hot water outlet pipe 5 and a cold water outlet pipe 6. The cold water outlet pipe 6 is directly connected to the inlet pipe 4, and the hot water outlet pipe 5 is connected to the outlet of the hot water assembly. Both the hot water outlet pipe 5 and the cold water outlet pipe 6 are connected to the faucet 3. Switches 7 are installed between the hot water outlet pipe 5, the cold water outlet pipe 6, and the faucet 3. If only cold water is needed, simply turn on the switch 7 connected to the cold water outlet pipe 6 to get cold water from the faucet 3. When hot water is needed, turn on the switch 7 connected to the hot water outlet pipe 5. Since the cold water is heated by the hot water assembly, hot water will come out of the faucet 3.

[0018] The hot water assembly includes a heating box 8, which is installed on the inner wall of the under-counter cabinet 2. A pair of electric heating coils 9 are installed inside the heating box 8. When hot water is needed, the electric heating coils 9 are activated, and the electric heating coils 9 will automatically heat the cold water entering through the water inlet pipe 4.

[0019] One of the electric heating coils 9 has a straight pipe 10 inside, and the other has a curved pipe 11 inside. The top ends of both the straight pipe 10 and the curved pipe 11 are connected to the hot water outlet pipe 5, and the bottom ends of both the straight pipe 10 and the curved pipe 11 are connected to the water inlet pipe 4. A double-way switch 12 is connected to the connection between the water inlet pipe 4 and the straight pipe 10 and the curved pipe 11. When the double-way switch 12 is controlled to supply water to the straight pipe 10, the water coming out of the faucet 3 is warm water because the length of the straight pipe 10 inside the electric heating coil 9 is shorter. When the double-way switch 12 is controlled to supply water to the curved pipe 11, the water coming out of the faucet 3 is hot water because the length of the curved pipe 11 inside the electric heating coil 9 is longer.

[0020] A knob 13 is installed on the outer wall of the under-counter cabinet 2. One end of the knob 13 is fixedly connected to the control shaft of the double-way switch 12. The double-way switch 12 can be controlled by turning the knob 13, which is convenient for operation.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
