Description

Technical Field

[0001] The utility model relates to the technical field of electric water faucets, in particular to a horizontal electric water faucet. Background Art

[0002] As we all know, faucet is the popular name for water valve, which is mainly used to control the size of the water flow switch and has the effect of saving water. With the continuous development of science and technology, faucets are constantly updated and iterated. Among them, electric water faucets were born.

[0003] Currently, electric water faucets, also known as quick-heating faucets, are efficient and quick faucets that can directly heat water. Like ordinary faucets, they can also be divided into vertical electric water faucets and horizontal electric water faucets based on the main body orientation. Vertical electric water faucets are aligned with the direction of water flow, so the internal pipe configuration can directly use straight pipes for water flow. However, horizontal electric water faucets have a different orientation and are 90° perpendicular to the direction of water flow. This configuration requires the installation of an internal diversion pipe with a steering function. In order to ensure the safety of the water temperature, a temperature sensor is installed at the water outlet. The thermometer is generally attached to the surface of the diversion pipe. However, due to the influence of the material and thickness of the diversion pipe itself, the temperature sensor is often prone to delays and errors when detecting the temperature, which brings difficulties to the existing diversion pipe design. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a horizontal electric water faucet.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A horizontal electric faucet comprises a casing, a temperature sensor, a circuit board mounted on the casing, and a water outlet pipe. A pipe body for introducing cold water and a heater having a water inlet and a water outlet are mounted inside the casing. The water inlet of the heater is connected to the pipe body. A faucet valve core is mounted on the pipe of the pipe body. A conducting pipe is mounted on the casing at the water outlet of the heater. The conducting pipe is U-shaped. One end of the conducting pipe is connected to the water outlet of the heater, and the other end of the conducting pipe is connected to the water outlet pipe. A mating hole is provided on the side of the conducting pipe. Both sides of the body of the temperature sensor are provided with mounting edges. The conducting pipe is provided with a receiving end surface on the side of the mating hole. The receiving end surface is provided with a threaded hole. The mounting edge is locked to the receiving end surface by a bolt. The detection head of the temperature sensor passes through the mating hole and is placed inside the conducting pipe. At least one sealing rubber ring is provided between the mating hole and the temperature sensor. The heater and the temperature sensor are both electrically connected to the circuit board.

[0007] Preferably, an impeller is provided in the pipeline of the tube body and can rotate as water flows in. The blades of the impeller are made of magnets. A thyristor is provided on the outside of the tube body and a Hall sensor is provided at the corresponding position of the impeller. The thyristor and the Hall sensor are both electrically connected to the circuit board.

[0008] Preferably, a first thermostat and a second thermostat are provided on the heater, the first thermostat is an automatic reset thermostat, the second thermostat is a manual reset thermostat, and both the first thermostat and the second thermostat are electrically connected to the circuit board.

[0009] Preferably, the heater is a cast aluminum heater.

[0010] Preferably, the water outlet and water inlet of the heater and the water inlet of the outlet pipe are all protruding outward and are covered with a soft rubber sleeve, the soft rubber sleeve is in the shape of a cone, the water inlet of the heater is connected to the water outlet of the pipe body through the soft rubber sleeve, the water outlet of the heater is connected to the water inlet of the conducting pipe through the soft rubber sleeve, and the water outlet pipe is connected to the water outlet of the conducting pipe through the soft rubber sleeve.

[0011] Preferably, an insulating tube is provided inside the water outlet pipe, and the insulating tube is communicated with the water outlet of the conducting pipe.

The cover plate is provided as a transparent portion at the display screen, and a touch icon is provided on the cover plate at the touch switch.

[0013] Due to the adoption of the above-mentioned scheme, the utility model relies on the U-shaped design of the conducting pipe to form conduction between the horizontally arranged heater and the water outlet pipe, thereby satisfying the guiding function of the horizontal faucet. At the same time, the temperature sensor is no longer directly attached to the outside of the conducting pipe, but a socket is directly opened to allow the detection head of the temperature sensor to be inserted into the inside of the conducting pipe, so that the temperature sensor is directly in contact with the water to be discharged, thereby ensuring the accuracy of temperature detection.

[0021] like Figures 1 to 3As shown, the present embodiment provides a horizontal electric faucet, comprising a housing 1, a temperature sensor 2, a circuit board 3 mounted on the housing 1, and a water outlet pipe 4. A pipe body 5 for introducing cold water and a heater 6 having a water inlet and a water outlet are installed inside the housing 1. The water inlet of the heater 6 is connected to the pipe body 5, and a faucet valve core 7 is installed on the pipeline of the pipe body 5. A conducting pipe 8 is installed at the water outlet of the heater 6 on the housing 1. The conducting pipe 8 is U-shaped, and one end of the conducting pipe 8 is connected to the water outlet of the heater 6, and the other end of the conducting pipe 8 is connected to the water outlet of the heater 6. It is connected to the water outlet pipe 4, and a socket 9 is provided on the side of the conducting pipe 8. The body of the temperature sensor 2 is provided with mounting edges 10 on both sides. The conducting pipe 8 is provided with a receiving end surface 11 on the side of the socket 9. The receiving end surface 11 is provided with a threaded hole. The mounting edge 10 is locked on the receiving end surface 11 by a bolt (not shown in the figure). The detection head of the temperature sensor 2 is placed inside the conducting pipe 8 through the socket 9. At least one sealing rubber ring 12 is provided between the socket 9 and the temperature sensor 2. The heater 6 and the temperature sensor 2 are both electrically connected to the circuit board 3.

[0022] This embodiment mainly relies on the U-shaped design of the conducting tube 8 to form conduction between the horizontally arranged heater 6 and the water outlet pipe 4, thereby satisfying the guiding function of the horizontal faucet. At the same time, the temperature sensor 2 is no longer directly attached to the outside of the conducting tube 8, but a socket 9 is directly opened to allow the detection head of the temperature sensor 2 to be inserted into the inside of the conducting tube 8, so that the temperature sensor 2 is directly in contact with the water to be discharged, thereby ensuring the accuracy of temperature detection. In addition, combined with the installation form of the sealing rubber ring 12 and the mounting edge 10, the temperature sensor 2 is directly used as both a temperature detector and a sealing member.

[0023] Furthermore, in order to prevent the occurrence of dry burning, that is, when no water flows in, the heater 6 needs to be stopped from working. Therefore, in this embodiment, an impeller 13 that can rotate after the water flows in is provided in the pipeline of the tube body 5. The blades of the impeller 13 are made of magnets. A thyristor 14 is provided on the outside of the tube body 5 and a Hall sensor 15 is provided at the corresponding position of the impeller 13. The thyristor 14 and the Hall sensor 15 are both electrically connected to the circuit board 3, and the operation of the heater 6 is controlled by the thyristor 14. In this way, when water flows through the tube body 5, the impeller 13 will be driven to rotate, and the blades are magnets. After the rotation occurs, the magnetic field between the blades of the impeller 13 will change, so that the Hall sensor 15 detects the change in the magnetic field and allows the heater 6 to perform heating. When the Hall sensor 15 does not detect the change in the magnetic field, it is determined that no water has flowed in, and the heater 6 will not be turned on. This can prevent the heater 6 from dry burning. Among them, in order for the impeller 13 to rotate when encountering water flow, a guide plate with an arc-shaped surface can be directly provided at the edge of the impeller 13, so that when the water flows in, a vortex can be formed, thereby driving the impeller 13 to rotate.

[0024] Furthermore, in order to prevent the heater 6 from heating at too high a temperature and to detect whether dry heating has occurred, a first thermostat 16 and a second thermostat 17 are provided on the heater 6 of this embodiment. The first thermostat 16 is an automatic reset thermostat and the second thermostat 17 is a manual reset thermostat. The first thermostat 16 and the second thermostat 17 are both electrically connected to the circuit board 3. Specifically, the set temperature of the automatic reset thermostat is 70°C, while the set temperature of the manual reset thermostat is 135°C. Generally, during normal operation, the automatic reset thermostat performs temperature detection, that is, when the heater 6 is working, the temperature is below 70°C, the heater 6 continues to work, and when the temperature exceeds 70°C, the heater 6 stops working, so that the temperature can be controlled below 70°C. Of course, if the automatic reset thermostat encounters an accident and does not trip, the temperature directly exceeds 70°C and continues to heat until it reaches 135°C. At this time, the manual reset sensor can be used to forcibly cut off the heater, and it will not automatically reset. It can only be manually reset after it is repaired. This can ensure heating safety. At the same time, the heater 6 in this embodiment is a cast aluminum heater.

[0025] Furthermore, in order to ensure the sealing between the pipe mouths of the components, the water outlet and water inlet of the heater 6 and the water inlet of the outlet pipe 4 are all protruding outward and are covered with a soft rubber sleeve 18. The soft rubber sleeve 18 is cone-shaped. The water inlet of the heater 6 is docked with the water outlet of the tube body 5 through the soft rubber sleeve 18, and the water outlet of the heater 6 is docked with the water inlet of the conducting pipe 8 through the soft rubber sleeve 18. The outlet pipe 4 is docked with the water outlet of the conducting pipe 8 through the soft rubber sleeve 18. In this way, relying on the cone-shaped soft rubber sleeve 18, the connection will become more and more dense as the connection is tightened.

[0026] Furthermore, to avoid electric shock, an insulating tube 19 is provided inside the outlet pipe 4 of this embodiment. The insulating tube 19 is connected to the water outlet of the conducting pipe 8. Specifically, the insulating tube 19 can be a soft rubber tube. Depending on the length of the insulating tube 19, an electrical isolation wall is formed inside the outlet pipe 4. Specifically, this wall utilizes the electrical resistance of water itself (for example, the national standard stipulates that the resistivity of tap water at 15°C should be greater than 1300Ω.cm). The "electrical isolation wall" is formed by selecting the insulating tube 19, combining the tube diameter and distance. When the heater 6 is powered on, even if the water contains electricity, it will be attenuated by the water's own resistance as it passes through the "electrical isolation wall," achieving the purpose of electrical isolation. This results in the discharged water having a voltage of almost zero and a very weak current of less than 0.02mA / kw.

[0027] Furthermore, in order to facilitate the user to know the specific working status and manual control work, the circuit board 3 of this embodiment is provided with a display screen 20 and a touch switch 21, and the housing 1 is covered with a cover plate 22 at the display screen 20 and the touch switch 21. The cover plate 22 is set as a transparent part at the display screen 20, and a touch icon is set on the cover plate 22 at the touch switch 21.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
