Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a water heater. Background Art

[0002] Existing low-end water heaters often use a mechanical pendulum thermometer to display the water temperature. The mechanical pendulum thermometer includes a case, a spring, a temperature-sensitive copper cap and a pointer. The temperature-sensitive copper cap is attached to the outer wall of the inner tank. When the water in the inner tank is heated, the water temperature will be transmitted from the metal inner tank. The temperature-sensitive copper cap receives the temperature and transmits it to the spring. Since the spring is connected to the pointer, the principle of thermal expansion and contraction of the spring is used to drive the swing of the pointer, and the pointer points to the temperature line to display the water temperature in the inner tank.

[0003] However, this mechanical pendulum thermometer is not only relatively old-fashioned and cannot meet the needs of modern products, but the reading process is not intuitive enough. In addition, the temperature of the outer wall of the inner tank displayed by the temperature-sensitive copper cap and the large error in the pointer swing indication process result in the displayed temperature being inaccurate, which seriously affects the user experience.

[0031] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0034] Reference below Figures 1-8 The specific structure of the water heater according to the embodiment of the present utility model is described.

[0035] The utility model provides a water heater with a high aesthetic appearance, and accurately displays the temperature of the hot water, which provides a good user experience. Figures 1 to 8 As shown, the water heater includes an outer shell 100, an inner tank 200 and a digital thermometer 300. The inner tank 200 is arranged in the outer shell 100, and a heating blind hole tube 220 is arranged in the inner tank 200. The digital thermometer 300 includes a temperature sensing wire 310, a temperature sensing probe 330 and a digital display component 350. The digital display component 350 is used to display a number representing the temperature value. The digital display component 350 is arranged on the outer shell 100. One end of the temperature sensing wire 310 is electrically connected to the digital display component 350, and the other end is connected to the temperature sensing probe 330. The temperature sensing probe 330 is placed in the heating blind hole tube 220.

[0036] Compared to existing water heaters that use mechanical pendulum thermometers, the water heater provided by the present invention uses a digital thermometer 300. Because the digital thermometer 300 can directly display a number representing the temperature—for example, a digital thermometer displaying 30 represents 30°C—the use of the digital thermometer 300 not only improves the aesthetics of the water heater but also makes it easier for users to read the temperature, enhancing the user experience. Furthermore, because the heating blind-hole tube 220 is disposed within the inner tank 200, the temperature sensing probe 330 is disposed within the heating blind-hole tube 220, placing the temperature sensing probe 330 closer to the hot water area within the inner tank 200 and ultimately providing more accurate temperature information.

[0037] Continue to refer to Figure 3 and Figure 4 As shown, in some embodiments, the first end of the heating blind-hole tube 220 is connected to the flange 210 of the inner liner 200, the second end of the heating blind-hole tube 220 extends to the middle of the inner liner 200, and the temperature sensing probe 330 is placed in the second end of the heating blind-hole tube 220. Placing the heating blind-hole tube 220 on the flange 210 can reduce the number of holes opened in the inner liner 200, thereby improving the structural strength of the inner liner 200 and reducing the risk of water leakage in the inner liner 200.

[0038] Optionally, the electrical room and flange 210 of the water heater are arranged on the same side of the water heater in the horizontal direction, the digital display component 350 is arranged on the side of the housing 100 close to the electrical room of the water heater, and the digital display thermometer 300 also includes a connecting wire 320, one end of the connecting wire 320 is electrically connected to the digital display component 350, and the other end is connected to the circuit in the electrical room.

[0039] This water heater disposes the digital display component 350 of the digital thermometer 300 on the side of the housing 100 near the electrical compartment, allowing the connection cable 320 to be powered by the circuitry within the electrical compartment. This makes powering and assembly of the digital thermometer 300 more convenient, eliminating the need for a separate power supply and reducing costs. The electrical compartment and the flange 210 of the inner tank 200 are located on the same horizontal side of the water heater, creating a more streamlined layout and reducing the required length of the temperature sensing cable 310 and the connection cable 320.

[0040] In some embodiments, as Figure 1 As shown, the housing 100 includes a cylindrical housing body 110 and a cover structure 120. One end of the housing body 110 forms an installation opening through which the inner container 200 can be installed within the housing 100. The cover structure 120 is positioned over the installation opening of the housing body 110 and serves to seal the installation opening. In some embodiments, the cover structure 120 defines an electrical compartment for mounting the electrical components of the water heater. In one specific embodiment, the housing body 110 is metal and the cover structure 120 is plastic. In another specific embodiment, both the housing body 110 and the cover structure 120 are plastic.

[0041] The inner liner 200 is used to hold water and includes a flange 210 disposed on one side. The flange 210 is used to mount the water heater's heating element, which extends into the inner cavity of the inner liner 200 and is used to heat the water within the inner liner 200. In some embodiments, the heating element includes the aforementioned heating blind-hole tube 220. Of course, the heating element also includes a ring-shaped heating tube for heating. Optionally, the flange 210 may also be mounted with an inlet pipe for supplying water to the inner liner 200 and an outlet pipe for discharging water. Integrating the inlet pipe, outlet pipe, and heating blind-hole tube 220 on the same flange 210 can reduce the number of holes drilled in the inner liner 200 and reduce the risk of leakage.

[0042] Continue to refer to Figure 8As shown, in some embodiments, the digital thermometer 300 further includes a case 340, which is disposed over a digital display component 350 and is detachably connected to the housing 100. The digital display component 350 is used to display a number representing the temperature value. Optionally, the digital display component 350 can be a small display screen or a device having multiple light tubes arranged in a "sun" shape. The digital display component 350 is connected to the temperature sensing wire 310 and the connecting wire 320.

[0043] Continue to refer to Figure 3 and Figure 8 As shown, the watch case 340 is snap-fitted to the outer shell 100. Specifically, a mounting hole is provided on the outer shell 100. The watch case 340 includes a light-transmitting main portion and a snap-fitting portion 341. The snap-fitting portion 341 is snap-fitted into the mounting hole. The light-transmitting main portion is used to transmit light so that the user can see the numbers displayed by the digital display component 350. Of course, in other embodiments, other methods can also be used to achieve a detachable connection between the watch case 340 and the outer shell 100, such as connection with a connector, magnetic attraction, etc.

[0044] In some embodiments, the mounting hole is a waist-shaped hole, and the cross-section of the light-transmitting main body is roughly waist-shaped. The light-transmitting main body is embedded in the mounting hole. Such a setting not only helps to improve the appearance of the water heater, but also helps to improve the clamping strength.

[0045] In some embodiments, multiple engaging portions 341 are provided, spaced apart circumferentially around the light-transmitting main body, with the engaging grooves of the engaging portions 341 engaging with the edges of the mounting holes formed in the housing 100. This arrangement can improve the mounting strength and stability of the digital thermometer 300 on the housing 100.

[0046] In some embodiments, the digital display component 350 is snap-connected to the watch case 340 . This arrangement makes the digital display component 350 and the watch case 340 easy to assemble and convenient to disassemble and maintain.

[0047] Continue to refer to Figure 1 As shown, in some embodiments, a temperature adjustment knob 400 is provided on one side of the housing 100 in the horizontal direction. By rotating the temperature adjustment knob 400, the heating amount of the heating component can be changed, thereby changing the heating efficiency of the water heater.

[0048] To improve wiring order, in some embodiments, a first clamp is provided on the inner wall of the housing 100. This clamp is used to clamp the temperature sensing cable 310. Alternatively, the clamp can be used to clamp the connection cable 320. Optionally, the first clamp is an elastic clamp with an adjustable opening. By clamping the temperature sensing cable 310 and the connection cable 320 within the first clamp, the neatness of the internal wiring of the water heater can be improved and the chance of damage to the temperature sensing cable 310 and the connection cable 320 can be reduced.

[0049] In some embodiments, a second clamping member is provided on the outer surface of the flange 210 to clamp the temperature sensing cable 310. Optionally, the second clamping member is an elastic collar with an adjustable opening. This arrangement improves the alignment of the temperature sensing cable 310 on the outer side of the flange 210 and prevents interference between the temperature sensing cable 310 and other components.

[0050] In some embodiments, the temperature sensing cable 310 includes a first, spirally-shaped telescopic portion, making the length of the temperature sensing cable 310 adjustable. By applying force to the first telescopic portion, the spacing between adjacent coils of the first telescopic portion can be changed, thereby varying the overall length of the temperature sensing cable 310, making the temperature sensing cable 310 suitable for water heaters of different specifications. Of course, in other embodiments, a retractable cable mechanism can also be provided on the temperature sensing cable 310, with a portion of the temperature sensing cable 310 wound around the retractable cable mechanism. By pulling the portion of the temperature sensing cable 310 exposed to the outside of the retractable cable mechanism or rotating the retractable cable mechanism, the effective length of the temperature sensing cable 310 can be adjusted.

[0051] In some embodiments, the connection cable 320 includes a spiral-shaped second telescopic portion, allowing the length of the connection cable 320 to be adjustable. Applying force to the second telescopic portion can change the spacing between adjacent coils of the second telescopic portion, thereby varying the overall length of the connection cable 320 and adapting the connection cable 320 to water heaters of varying specifications. In other embodiments, the connection cable 320 may also be provided with a retractable mechanism, with a portion of the connection cable 320 wound around the retractable mechanism. The effective length of the connection cable 320 can be adjusted by pulling the portion of the connection cable 320 exposed outside the retractable mechanism or by rotating the retractable mechanism.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
