Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a dual-purpose faucet for purified water and tap water. Background Art

[0002] The structure of existing two-in-one faucets for purified water and tap water is mostly like the purified water and tap water switching faucet disclosed in Chinese patent CN205896282U, which has a filter assembly arranged on the faucet body. By operating the handle to rotate the combined valve core, the outflow of cold water, hot water or mixed water can be controlled; by rotating the water diversion valve core, purified water or tap water can flow out. In this solution, although the two functions of producing purified water and tap water are combined, the structure is complex and only cold purified water can be produced. When hot purified water is needed, the cold purified water must first be placed in a kettle or other heating device for heating, which is relatively inconvenient. In addition, in this solution, the filter core is set on the faucet body. On the one hand, this increases the size of the faucet body and occupies a large space on the countertop, which is not conducive to user operation. Moreover, due to the limited space on the countertop, the volume of the filter core, the number of filter layers of the filter core, and the thickness of the filter layer are all affected, resulting in the filter core needing to be replaced frequently, which is inconvenient for users.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0038] Combine Figures 1 to 8 This embodiment provides a dual-purpose faucet for purified water and tap water, including a faucet body 1, on which is disposed a water outlet pipe 2, a control valve 3 and an operating handle 41, wherein the water outlet pipe 2 is disposed at the water outlet end of the faucet body 1; the control valve 3 is built into the faucet body 1, for controlling the connection and disconnection of tap water and the water outlet pipe 2; the operating handle 41 is adaptively connected to the faucet body 1, and is linked to the control structure 4, and the control structure 4 is constructed to be electrically or wirelessly connected to the electric control valve installed on the outside of the faucet body; the operating handle is driven in an operable manner to trigger the electric control valve to control the connection and disconnection of the purified water source under the console and the water outlet pipe 2.

[0039] In a preferred embodiment, the control valve 3 is a three-inlet, two-outlet valve for controlling the flow of cold and hot tap water and cold purified water, and the electric control valve for controlling the flow of hot purified water. Specifically, a valve seat 5 is mounted or formed on the faucet body 1. The valve seat 5 is provided with a cold tap water channel 51, a hot tap water channel 52, a mixed water channel 53, a cold purified water inlet channel 54, a cold purified water outlet channel 55, and a hot purified water outlet channel 56. The cold purified water inlet channel 54 is connected to the under-counter purified water source, and the hot purified water outlet channel 56 is connected to the water outlet of the under-counter heater. The water inlet of the heater is connected to the under-counter purified water source. The outlet pipe 2 is mounted on the outlet end of the valve seat 5. The control valve 3 is used to control the flow of cold and hot tap water channels and the mixed water channel 53, as well as the flow of cold purified water inlet channel 54 and the cold purified water outlet channel 55. The electric control valve is used to control the flow of the water inlet or outlet of the heater. Furthermore, the control valve 3 includes a cold tap water hole, a hot tap water hole, a mixing water hole, a water inlet hole, and a water outlet hole. The cold tap water hole is connected to the cold tap water channel 51, the hot tap water hole is connected to the hot tap water channel 52, the mixing water hole is connected to the mixing water channel 53, the water inlet hole is connected to the cold purified water inlet channel 54, and the water outlet hole is connected to the cold purified water outlet channel 55. A control handle 31 is connected to the control valve 3. The control valve 3 is configured to be operable to adjust the flow of the cold purified water inlet channel 54 and the cold purified water outlet channel 55 by rotating the control handle 31 in a first direction, and to adjust the flow of the cold and hot tap water channels and the mixing water channel 53 by toggling the control handle 31 in a second direction. The direction around the axis of the control valve 3 is the first direction, and the extending direction along the axis of the control valve 3 is the second direction. When the controllable handle 31 is directly turned, the cold purified water flows from the cold purified water inlet channel 54 into the water inlet hole, and flows from the water inlet hole to the water outlet hole, and finally flows out from the cold purified water outlet channel 55 connected to the water outlet hole. Figure 3 By turning the handle to the right, the cold and hot tap water holes are connected to the mixing water hole, and the control handle 31 can be turned in this state to adjust the mixed water temperature, but it is not limited to this. Among them, the internal structure of the three-inlet and two-outlet valve is prior art and will not be repeated here.

[0040] In another embodiment, the control valve 3 is used to control the on-off of cold and hot tap water, and the electric control valve is used to control the on-off of cold purified water and hot purified water. Figure 9The under-counter purified water source has a first water outlet waterway and a second water outlet waterway, a first electrically controlled valve is arranged on the first water outlet waterway, the second water outlet waterway is connected to the water inlet end of the under-counter heater, and a second electrically controlled valve is arranged at the water outlet end of the heater. In other embodiments, the electrically controlled valve can also be a solenoid valve with one inlet and two outlets, wherein the water inlet is used to be connected to the under-counter purified water source, the first water outlet is used to be connected to the water outlet pipe 2, the second water outlet is used to be connected to the water inlet end of the heater, and the water outlet end of the heater is connected to the water outlet pipe 2. The electrically controlled valve is preferably a solenoid valve with one inlet and two outlets, and the water inlet is connected to the first water outlet or the second water outlet by operating the handle. When the water inlet is connected to the first water outlet, the water outlet pipe 2 discharges cold purified water, and when the water inlet is connected to the second water outlet, the water outlet pipe 2 discharges hot purified water, separating the purified water control and the tap water control, making it convenient for users to select and avoiding user misoperation. The first water outlet is connected to the first water passage on the valve seat 5 via a flexible hose. The water outlet of the heater is connected to the second water passage on the valve seat 5 via a flexible hose. Both the first and second water passages are connected to the outlet pipe 2. The structure and circuit principles of the one-inlet, two-outlet solenoid valve are prior art and will not be elaborated here. Placing the electrically controlled valve under the counter simplifies the water path of the faucet body 1, thereby reducing the body's volume and reducing design restrictions.

[0041] It should be noted that in this embodiment, by providing a control valve and an operating handle for triggering the electric control valve, the control of tap water, cold purified water, and hot purified water is achieved, making it convenient for users to use. Among them, the water source for the under-counter purified water can be water filtered by a filter element, water filtered by a water purifier, or bottled mineral water, purified water, or distilled water, ozone water, etc. The structure and working principle of the heater are existing technologies and will not be repeated here. Among them, placing the purified water under the counter can simplify the faucet structure and reduce the space occupied by the faucet on the counter. At the same time, the under-counter purified water can also facilitate the installation of the filter element or water purifier, and the volume of the filter element can be made larger, thereby reducing the frequency of filter element replacement. In addition, by providing a cold purified water inlet channel 54, a cold purified water outlet channel 55, and a hot purified water outlet channel 56 on the valve seat 5, and using the control valve 3 to control the cold purified water and the electric control valve to control the hot purified water, independent control of cold purified water and hot purified water can be achieved, thereby combining cold and hot tap water and cold and hot purified water on a single faucet, making it convenient for users to use hot purified water and meeting the needs of different usage scenarios. Only the valve seat 5 and two valve cores need to be provided, the structure is simple, and the cost of the faucet can be reduced.

[0042] For example, when a user needs to use tap water, the control valve 3 is driven to connect the cold and hot tap water channels with the mixed water channel 53, and the corresponding tap water flows out of the water outlet pipe 2. When the user needs cold purified water, the control valve 3 is opened to connect the cold purified water inlet channel 54 with the cold purified water outlet channel 55, and cold purified water flows out of the water outlet pipe 2. When the user needs hot purified water, the electric control valve is driven to open to allow the hot purified water on the heater to flow to the hot purified water outlet channel 56, and hot purified water flows out of the water outlet pipe 2. Among them, an inner water outlet pipe can be provided in the water outlet pipe 2 corresponding to the mixed water channel 53, the cold purified water outlet channel 55, and the hot purified water outlet channel 56, and a corresponding water outlet nozzle is provided at the water outlet end of each inner pipe. The user can further judge whether the outflowing water is tap water, cold purified water, or hot purified water by the position of the water outlet nozzle, and it can also avoid the purified water and tap water sharing a pipe, which causes the contamination of the purified water. Of course, a water outlet cavity can also be provided at the water outlet end of the valve seat 5, with the water outlet pipe 2 communicating with the water outlet cavity, the mixed water channel 53, the cold purified water outlet channel 55, and the hot purified water outlet channel 56 all communicating with the water outlet pipe 2, and a water outlet nozzle provided on the water outlet pipe 2, through which tap water, cold purified water, and hot purified water all flow. This is not limited to this and is not specifically limited.

[0043] In a preferred embodiment, the electrically controlled valve is preferably a solenoid valve, the control structure includes a control component, the operating handle 41 is mounted on the faucet body 1, and the solenoid valve is electrically connected to the control component. Exemplarily, the electrically controlled valve is arranged between the clean water source under the counter and the water inlet of the heater. The heater and the clean water source are connected by a hose. The solenoid valve is arranged between the water inlet of the heater and the clean water source, so that the heater does not need to be constantly under the water supply pressure, which can extend the service life of the heater. At the same time, the heater is installed under the counter, which can facilitate the maintenance and installation of the heater. In other embodiments, the solenoid valve can also be arranged between the water outlet of the heater and the hot clean water outlet channel 56.

[0044] Preferably, the operating handle 41 is configured to trigger the control component to drive the solenoid valve to open and close by rotating, pressing, touching or approaching. For example, an infrared sensing module is provided on the operating handle 41 to send a signal to the control component when the human body approaches the infrared sensing detection window, so that the control component drives the solenoid valve to open. Alternatively, the control component is a circuit board, and a button is provided on the circuit board, and the button is triggered by pressing the operating handle 41. In other embodiments, the control component can also be arranged under the table, and a signal detection module can be arranged on the operating handle 41, and a corresponding electrical signal is sent to the control component through the signal detection module, so that the control component drives the solenoid valve to open and close. Among them, the circuit principle and structure between the circuit board and the solenoid valve are existing technologies and will not be repeated here.

[0045] In other embodiments, a wire passage 57 is provided on the valve seat 5 or between the valve seat 5 and the faucet body 1. The control circuit passes through the wire passage 57 to connect to the solenoid valve located under the counter. Preferably, the wire passage is provided on the valve seat 5, making the valve seat 5 compact and saving space.

[0046] Based on the above embodiment, in an alternative embodiment of the present invention, the faucet body 1 is provided with an assembly cavity 11, the valve seat 5 is positioned within the assembly cavity 11, and the outlet pipe 2 is mounted on the valve seat 5 and secured to the valve seat 5 via a fastener 21 provided on the side. The fastener 21 may be a screw that is inserted from the side of the faucet body 1 and connects with a mounting hole in the outlet pipe 2 to secure the outlet pipe 2 to the valve seat 5. The valve seat 5 may be made of plastic to save costs.

[0047] Preferably, the faucet body 1 is cross-shaped, with the outlet pipe 2 mounted on its upper end and the mounting pipe 6 connected to its lower end. A first mounting cavity 12 for mounting the control valve 3 and a second mounting cavity 13 for mounting the operating handle 41 are formed on either side. The inner walls of both the first mounting cavity 12 and the second mounting cavity 13 are threaded. The control valve 3 is threadedly connected to the threaded connection via a gland 32 to secure it to the valve seat 5. The operating handle 41 is fixedly connected to the threaded connection at one end, with the other end exposed in the second mounting cavity 13. The cross-shaped faucet body 1 has a simple appearance. The control valve 3 and the operating handle 41 are disposed on opposite sides of the faucet body 1, making them less likely to be confused, preventing user error and facilitating ease of use. During installation, the valve seat 5 is inserted into the faucet body 1 until it is in position. The control valve 3 is then placed into the first mounting cavity 12 and the gland 32 is screwed in, ensuring that the control valve 3 abuts the valve seat 5. The operating handle 41 is then threaded into the second mounting cavity 13 to secure it. The outlet pipe 2 is then inserted into the valve seat 5 and tightened from the side with screws. The control valve 3 and the control handle 31 can also be secured with side-locking screws. This structure facilitates assembly and disassembly, improves production efficiency, and facilitates after-sales service and maintenance.
