Description

Technical Field

[0001] The utility model belongs to the technical field of electric water faucets, and in particular relates to an electric water faucet with a non-contact temperature control device. Background Art

[0002] The widespread use of tap water has brought convenience to people, but if you want to use hot water, you need to install heating equipment, and electric water faucets are one of the most widely used ones. For safety reasons, overheating protection devices are usually installed on electric water faucets.

[0003] The traditional electric hot water faucet protection device is a disposable thermal fuse device, which works in such a way that when the temperature is too high, the thermal fuse fuses and the circuit is disconnected. When it is needed to be used again, the disposable thermal fuse device needs to be reinstalled, which is not reusable and inconvenient to repair.

[0004] For example, the Chinese patent with the patent publication number CN219868547U discloses a manual reset control mechanism for an electric water faucet, including: a control mechanism, and a faucet body arranged on the control mechanism for discharging water; the control mechanism includes a water storage tank, the water storage tank is connected to the bottom of the faucet body, and a heating component arranged inside the water storage tank; and a manual reset mechanism arranged at the bottom of the heating component. When the heating component is abnormally high in temperature, the utility model can timely monitor and immediately cut off the internal circuit of the machine, and at the same time make the reset button on the thermostat automatically jump up, and when the temperature of the heating component is lower than the nominal value of the thermostat, it is necessary to manually reset it to avoid the machine from automatically restoring the reset button of the thermostat due to a malfunction, so that the machine continues to heat, thereby effectively preventing dangerous accidents such as dry burning, combustion, explosion, and fire of the electric water faucet.

[0005] However, the patent still has the following problems:

[0006] First, heat-conducting columns are arranged on the side wall of the heating tube body, which requires additional processing on the tube wall, which will destroy the structural integrity of the heating tube and form stress concentration points. Moreover, when the heating tube expands and contracts due to heat and cold, these points are prone to cracks or breakage, thus reducing the service life.

[0007] Second, the heat distribution on the outer wall of the heating tube is uneven, and the heat obtained by the heat-conducting column here has local differences. This difference will make the temperature signal of the thermostat inaccurate and cause the thermostat to malfunction, which may cause the danger of too high water temperature or hygiene and usage problems due to too low water temperature. Utility Model Content

[0008] The main technical problem to be solved by the present utility model is to provide an electric water faucet with a non-contact temperature control device, which has a reasonable structural design, is convenient to operate, avoids damaging the structure of the heating pipe, and the thermostat can more accurately sense the change of water temperature.

[0009] To solve the above technical problems, the present utility model provides the following technical solutions:

[0010] An electric water faucet with a non-contact temperature control device, comprising a faucet body. A heating cavity and an electrical control cavity are arranged in the faucet body, and the electrical control cavity is separated from the heating cavity by a sealing plate. A heating circuit and a water pressure switch are arranged in the electrical control cavity, a heating pipe is arranged in the heating cavity, and both the heating pipe and the water pressure switch are connected to the heating circuit. A non-contact temperature control device is arranged in the heating circuit;

[0011] The non-contact temperature control device includes a heat conduction column. One end of the heat conduction column extends into the electrical control cavity and does not contact the heating pipe. The other end of the heat conduction column penetrates through the sealing plate and extends into the heating cavity and is in contact connection with a thermostat. A manual reset component for manually resetting the thermostat is arranged on the other side of the thermostat.

[0012] The following are further optimizations of the above technical solutions by the present utility model:

[0013] An installation cylinder is integrally formed on the sealing plate. The two ends of the installation cylinder are respectively communicated with the heating cavity and the electrical control cavity. A first stepped hole, a second stepped hole and a third stepped hole are sequentially arranged in the installation cylinder, and the diameter of the second stepped hole is smaller than the diameters of the first stepped hole and the third stepped hole.

[0014] Further optimization: The temperature sensing end of the thermostat is inserted into the first stepped hole, one end of the heat conduction column is in fit with the temperature sensing end of the thermostat, and the other end of the heat conduction column sequentially passes through the first stepped hole, the second stepped hole and the third stepped hole and extends into the heating cavity.

[0015] Further optimization: The heat conduction column includes a first column body and a second column body. The first column body has an interference fit with the third stepped hole, and the second column body has an interference fit with the second stepped hole. An annular sealing groove is formed on the outer side wall of the first column body close to the second column body, and a sealing ring is installed in the annular sealing groove. A sealing ring is also sleeved at the connection part of the second column body and the first column body.

[0016] Further optimization: The manual reset component includes an inner cover detachably installed at one end of the faucet body. A connecting cylinder is integrally formed on the inner side wall of the inner cover, and the two ends of the connecting cylinder are respectively communicated with the electrical control cavity and the outside.

[0017] Further optimization: An interference fit sleeve is provided at one end of the connecting cylinder away from the inner cover, and the other side of the interference fit sleeve is in contact with the thermostat. The thermostat reset button is located inside the interference fit sleeve and is concentric with the interference fit sleeve.

[0018] Further optimization: The connecting cylinder is successively provided with a first connection hole and a second connection hole, and the diameter of the first connection hole is smaller than that of the second connection hole.

[0019] Further optimization: A movable rod is slidably arranged in the second connection hole, and there is a clearance fit between the movable rod and the second connection hole. The axial length of the movable rod is smaller than the axial length of the second connection hole.

[0020] Further optimization: One end of the movable rod close to the inner cover is integrally connected with a button rod. The button rod successively passes through the second connection hole and the first connection hole and extends to the outside. There is a sliding fit between the button rod and the first connection hole. The axial length of the button rod is greater than the axial length of the first connection hole.

[0021] Further optimization: The other end of the movable rod is integrally connected with a reset rod. The other end of the reset rod slidably penetrates through the reset rod plug and is in contact with the reset button of the thermostat.

[0022] In the present utility model, the heat conducting column does not directly contact the heating tube, avoiding additional processing on the outer wall of the heating tube, thus eliminating the problem of damaging the structural integrity of the heating tube due to drilling holes in the tube wall or installing components. Stress concentration points will not be generated, greatly reducing the possibility of cracks or breakage caused by thermal expansion and contraction, and ensuring the normal service life of the heating tube.

[0023] In the present utility model, one end of the heat conducting column extends into the heating cavity but does not contact the heating tube. Instead, it obtains heat through the water in the heating cavity. This indirect heat conduction method utilizes the heat transfer characteristics of the water in the heating cavity. Since the water in the heating cavity is flowing and has a certain heat balance ability, even if the heat distribution on the outer wall of the heating tube is uneven, after natural convection and heat diffusion of the water in the heating cavity, the heat transferred to the heat conducting column will be relatively uniform. Thus, the thermostat can more accurately sense the water temperature change, avoiding misoperation of the thermostat, and further avoiding too high or too low water temperature, improving the comfort and safety of user use.

[0024] The present utility model will be further described below in conjunction with the drawings and embodiments. Description of the Drawings

Detailed implementation manners

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] AsFigure 1-7 As shown in the figure, an electric water faucet with a non-contact temperature control device 6 includes a faucet body 1. Inside the faucet body 1, there is a heating cavity 2 and an electrical control cavity 3. The electrical control cavity 3 and the heating cavity 2 are separated by a sealing plate 4. Inside the electrical control cavity 3, there is a heating circuit and a water pressure switch. Inside the heating cavity 2, there is a heating pipe 5. Both the heating pipe 5 and the water pressure switch are connected to the heating circuit. A non-contact temperature control device 6 is provided inside the heating circuit;

[0036] The non-contact temperature control device 6 includes a heat conduction column 61. One end of the heat conduction column 61 extends into the heating cavity 2 and does not contact the heating pipe 5. The other end of the heat conduction column 61 penetrates through the sealing plate 4 and extends into the electrical control cavity 3 and is in contact connection with a temperature controller 62. On the other side of the temperature controller 62, there is a manual reset assembly 63 for manually resetting the temperature controller 62.

[0037] With such a design, first of all, its heat conduction column 61 does not directly contact the heating pipe 5, avoiding additional processing on the outer wall of the heating pipe 5, thus eliminating the problem of damaging the structural integrity of the heating pipe 5 due to drilling holes in the pipe wall or installing components. No stress concentration points will be generated, greatly reducing the possibility of cracks or breakage caused by thermal expansion and contraction, and ensuring the normal service life of the heating pipe 5.

[0038] Secondly, one end of the heat conduction column 61 extends into the heating cavity 2 but does not contact the heating pipe 5. Instead, it obtains heat through the water in the heating cavity 2. This indirect heat conduction method utilizes the heat transfer characteristics of the water in the heating cavity 2. Since the water in the heating cavity 2 is flowing and has a certain heat balance ability, even if the heat distribution on the outer wall of the heating pipe 5 is uneven, after natural convection and heat diffusion of the water in the heating cavity 2, the heat transferred to the heat conduction column 61 will be relatively uniform. Thus, the temperature controller 62 can more accurately sense the water temperature change, avoiding misoperation of the temperature controller 62, and further avoiding the water temperature being too high or too low, improving the comfort and safety of user use.

[0039] In this embodiment, the heating pipe 5, the heating circuit, the water pressure switch, and the temperature controller 62 are all prior arts and are well-known technologies to those of ordinary skill in the art. Therefore, they will not be described in detail in this embodiment.

[0040] An installation cylinder 7 is integrally formed on the sealing plate 4. The two ends of the installation cylinder 7 are respectively communicated with the heating cavity 2 and the electrical control cavity 3.

[0041] With such a design, the installation cylinder 7 integrally formed on the sealing plate 4 reduces the connection parts, reduces the possibility of problems caused by connection looseness or poor sealing, and at the same time is easier to ensure accuracy and quality during the processing, ensuring a stable and reliable separation between the heating cavity 2 and the electrical control cavity 3.

[0042] A first stepped hole 71, a second stepped hole 72 and a third stepped hole 73 are sequentially arranged in the installation cylinder 7, and the diameter of the second stepped hole 72 is smaller than the diameters of the first stepped hole 71 and the third stepped hole 73.

[0043] The temperature sensing end of the thermostat 62 is inserted into the first stepped hole 71, and there is an interference fit between the temperature sensing end of the thermostat 62 and the first stepped hole 71.

[0044] One end of the heat conducting column 61 is attached to the temperature sensing end of the thermostat 62, and the other end of the heat conducting column 61 sequentially passes through the first stepped hole 71, the second stepped hole 72 and the third stepped hole 73 and extends into the heating cavity 2.

[0045] The heat conducting column 61 includes a first column body 611 and a second column body 612, and there is an interference fit between the first column body 611 and the third stepped hole 73, and there is an interference fit between the second column body 612 and the second stepped hole 72.

[0046] An annular sealing groove 613 is formed in the outer side wall of the first column body 611 close to the second column body 612, and a sealing ring 614 is installed in the annular sealing groove 613, and a sealing ring 614 is also sleeved on the second column body 612 at the connection with the first column body 611.

[0047] With such a design, first of all, the heat conducting column 61 has an interference fit with the corresponding stepped hole, and can be stable in the installation cylinder 7 during water flow impact, vibration and thermal expansion and contraction, maintaining a stable heat conduction path and ensuring accurate transmission of temperature signals.

[0048] Secondly, the diameter of the second stepped hole 72 is smaller than other holes, and it has a tight fit with the heat conducting column 61 to form a labyrinth sealing effect. At the same time, an annular sealing groove 613 and a sealing ring 614 are arranged on the first column body 611 and a sealing ring 614 is sleeved on the second column body 612, so that multiple sealing lines of defense are formed between the heat conducting column 61 and the installation cylinder 7, thereby effectively preventing water and water vapor in the heating cavity 2 from leaking into the electrical control cavity 3, protecting electrical components from water damage, and ensuring the safe operation of the electric water faucet.

[0049] Thirdly, the heat conducting column 61 is closely attached to the temperature sensing end of the thermostat 62, without heat insulation media such as air gaps, and has high heat conduction efficiency. Moreover, the stepped hole design ensures the stability of the heat conducting column 61 and maintains close contact for a long time, continuously providing accurate temperature signals for the thermostat 62.

[0050] Finally, the interference fit between the heat conducting column 61 and the stepped hole can adapt to thermal expansion and contraction caused by temperature changes, limit and guide the expansion direction of the heat conducting column 61, maintain close contact and good sealing with surrounding components, and the space between the stepped holes provides a buffer for the expansion of components, preventing damage or sealing failure.

[0051] The manual reset component 63 includes an inner cover 631 detachably installed at one end of the faucet body 1. A connecting cylinder 632 is integrally formed on the inner side wall of the inner cover 631. The two ends of the connecting cylinder 632 are respectively communicated with the electrical control cavity 3 and the outside.

[0052] An interference fit is provided with a reset rod plug 633 at the end of the connecting cylinder 632 far from the inner cover 631. The other side of the reset rod plug 633 is in contact with the thermostat 62. The reset button of the thermostat 62 is located inside the reset rod plug 633 and is concentric with the reset rod plug 633.

[0053] A first connection hole 6321 and a second connection hole 6322 are sequentially arranged in the connecting cylinder 632. The diameter of the first connection hole 6321 is smaller than the diameter of the second connection hole 6322.

[0054] A movable rod 634 is slidably arranged in the second connection hole 6322. There is a clearance fit between the movable rod 634 and the second connection hole 6322. The axial length of the movable rod 634 is smaller than the axial length of the second connection hole 6322.

[0055] In this embodiment, the axial length of the movable rod 634 is smaller than the axial length of the second connection hole 6322 by 2 mm to 3 mm.

[0056] One end of the movable rod 634 close to the inner cover 631 is integrally connected with a button rod 635. The button rod 635 sequentially passes through the second connection hole 6322 and the first connection hole 6321 and extends to the outside.

[0057] There is a sliding fit between the button rod 635 and the first connection hole 6321. The axial length of the button rod 635 is greater than the axial length of the first connection hole 6321.

[0058] In this embodiment, the axial length of the button rod 635 is greater than the axial length of the first connection hole 6321 by 5 mm - 7 mm.

[0059] The other end of the movable rod 634 is integrally connected with a reset rod 636. The other end of the reset rod 636 slidably penetrates through the reset rod plug 633 and is in contact with the reset button of the thermostat 62.

[0060] An outer cover 637 is sleeved outside the inner cover 631. The outer cover 637 is detachably connected to the faucet body 1.

[0061] With such a design, first, the inner cover 631 is installed at one end of the faucet body 1. By pressing the button rod 635 extending to the outside, the reset of the thermostat 62 can be realized, which is convenient for the user to operate. No complex tools or professional knowledge are required, enabling the user to easily complete the reset operation and improving the convenience of product use.

[0062] Secondly, one end of the connecting cylinder 632 is interference-fitted with the reset rod plug 633, ensuring the stability of contact with the thermostat 62. Moreover, the movable rod 634, the button rod 635, and the reset rod 636 are integrally connected. When the button rod 635 is pressed, the force can be effectively transmitted to the reset button of the thermostat 62. At the same time, the reset button of the thermostat 62 is located inside the reset rod plug 633 and is concentrically arranged, ensuring that each press can accurately trigger the reset, improving the accuracy and reliability of the reset operation.

[0063] Thirdly, the movable rod 634 is in clearance fit with the second connecting hole 6322, and the axial length of the movable rod 634 is less than the axial length of the second connecting hole 6322. The button rod 635 is in sliding fit with the first connecting hole 6321, thus providing a reasonable movement space for the movable rod 634 and the button rod 635 during the operation process. Furthermore, it can avoid the jamming phenomenon caused by factors such as machining errors, thermal expansion and contraction, or slight component deformation, ensuring that the manual reset assembly 63 can work properly in various environments.

[0064] Thirdly, the inner cover 631 and the outer cover 637 are detachably connected to the faucet body 1. When problems occur with the manual reset assembly 63, such as damage to the movable rod 634, the button rod 635, or the reset rod 636, etc., it can be conveniently disassembled for repair or replacement, reducing the maintenance cost and difficulty and extending the service life of the product.

[0065] On the faucet body 1, an inlet water assembly, a cold and hot water control assembly, an outlet water assembly, a heating control assembly, a temperature display assembly, etc. are also provided as required.

[0066] The structures, working principles, installation principles, etc. of the inlet water assembly, the cold and hot water control assembly, the outlet water assembly, the heating control assembly, or the temperature display assembly all constitute the prior art and are well-known to those of ordinary skill in the art, so they will not be elaborated here.

[0067] During use, first, when the faucet is in the closed state, the entire system is in the standby state. The heating circuit is not connected, the heating tube 5 does not work, the water temperature in the heating chamber 2 is in the initial state, the thermostat 62 is in the state of preparing to monitor the temperature, and there is no operation requirement for the manual reset assembly 63.

[0068] When the user opens the faucet, water flows into the faucet body 1, and the water pressure generated by the water flow acts on the water pressure switch. The water pressure switch closes under the action of the water pressure, connecting the heating circuit. Subsequently, the current passes through the heating tube 5. Due to the resistance characteristics of the heating tube 5, electrical energy is converted into heat energy, and the water in the heating chamber 2 starts to be heated.

[0069] As the heating progresses, the water temperature in the heating chamber 2 gradually rises, and the heat is transferred to the heat conduction column 61 located in the heating chamber 2 in the form of heat conduction. The heat conduction column 61 transfers the heat to the temperature controller 62, and the temperature controller 62 monitors the temperature change in real time and compares the measured temperature with the preset temperature set value.

[0070] When the water temperature does not reach the upper limit of the preset normal operating temperature, the heating circuit continues to supply power normally, the heating tube 5 remains in the heating state, and the water temperature continues to rise; when the water temperature rises close to the upper limit of the preset normal operating temperature, the temperature controller 62 sends an adjustment signal to the heating circuit according to the temperature signal. After receiving the signal, the heating circuit can take measures such as reducing the heating power to maintain the water temperature within a suitable range and prevent the water temperature from being too high; when the water temperature exceeds the upper limit of the preset safety temperature, the temperature controller 62 will immediately trigger the protection mechanism, and the reset button will automatically pop up. At this time, the temperature controller 62 sends a signal to stop heating to the heating circuit, cuts off the heating circuit, and makes the heating tube 5 stop heating, avoiding safety hazards such as scalding users or damaging equipment caused by too high water temperature.

[0071] When the temperature controller 62 needs to be automatically reset, the user presses the button rod 635 located on the outside. After the button rod 635 is stressed, it moves towards the inside of the connecting cylinder 632. Since the button rod 635 is integrally connected to the movable rod 634, the movement of the button rod 635 drives the movable rod 634 to slide axially in the second connection hole 6322. The sliding of the movable rod 634 further drives the reset rod 636 to slide in the reset rod plug 633. The reset rod 636 moves towards the temperature controller 62, and the reset rod 636 passes through the reset rod plug 633, accurately transferring the pressing force to the reset button of the temperature controller 62 to reset the temperature controller 62.

[0072] For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principles and spirit of the present utility model, the changes, modifications, substitutions, and variations made to the embodiments still fall within the protection scope of the present utility model.
