Description

Technical Field

[0001] This utility model relates to the field of instant hot water dispenser technology, and in particular to an instant hot water dispenser with dual heating tubes. Background Technology

[0002] An instant hot water dispenser is a high-tech, intelligent, and innovative water dispenser that provides hot water instantly with the touch of a button, unlike traditional water dispensers that require repeated heating. Generally, existing instant hot water dispensers operate on approximately 220V and have a power consumption of approximately 2200W.

[0003] With globalization, people are living, working, and traveling more frequently in different countries and regions, leading to a growing demand for instant water dispensers that can operate stably under varying voltage conditions. Traditional instant water dispensers typically only have a single heating element with a fixed voltage, making them unsuitable for different countries' voltage standards. This results in numerous inconveniences when used in different regions, such as low heating efficiency and equipment damage.

[0004] Therefore, there is a need for an instant hot water dispenser that is suitable for both high and low voltage. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides an instant hot water dispenser with dual heating tubes.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A dual-heating-tube instant water dispenser has a heating element and a circuit board inside the dispenser body. The heating element and the circuit board are electrically connected. The heating element includes a water pipe, and a dual-heating-tube assembly is provided on the side of the water pipe. The working state of the dual-heating-tube assembly is controlled by a voltage detection and switching module on the circuit board.

[0008] Preferably, the dual heating tube assembly includes two hollow pipes, which are located on both sides of the water pipe and each pipe is equipped with a heating tube.

[0009] Preferably, the water inlet protrudes from the pipe openings on both sides, the water inlet and the two pipes are integrally formed, and the heating pipe is placed inside the hollow pipe.

[0010] Preferably, the water pipe is provided with a flow-deflecting element to assist in heat conduction.

[0011] Preferably, the turbulence-disrupting element is a rib protruding from the inner wall of the water pipe or a stainless steel spring placed inside the water pipe.

[0012] Preferably, the heating element is configured as two heating elements with different voltages and installed in the pipes on both sides of the water pipe.

[0013] Preferably, the water pipe and the pipeline have a U-shaped structure, with the two ports of the water pipe being higher than the ports of the pipeline on both sides.

[0014] Preferably, the dual heating tube assembly can withstand voltages from 100V to 240V.

[0015] Preferably, the water outlet end of the water pipe is connected to the water outlet nozzle through the water outlet pipe, and a temperature sensor is connected to the water outlet pipe. One end of the temperature sensor is inserted into the water outlet pipe, and the temperature sensor is electrically connected to the circuit board through a wire.

[0016] Preferably, the water dispenser body includes a base and an outer frame. The heating element and the circuit board are mounted on the base via a fixing bracket. The upper end of the outer frame is also provided with a detachable water inlet.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] A dual-heating-tube instant water dispenser features a dual-heating-tube assembly whose operating state is controlled by a built-in voltage detection and switching module. When a low input voltage is detected, it automatically switches to the first heating tube for heating; when a high input voltage is detected, it automatically switches to the second heating tube for heating. No manual operation by the user is required, ensuring stable operation of the device under different voltage environments. Through the dual-heating-tube design and automatic switching, efficient heating is ensured under different voltage conditions, meeting the user's need for quick hot water. In certain low-voltage operating conditions, both heating tubes can work together to achieve the required water temperature and flow rate. Attached Figure Description

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] like Figures 1 to 4 As shown in the figure, this is the first embodiment of the present utility model. The water dispenser body 1 is provided with a heating element 2 and a circuit board 3 inside. The heating element 2 and the circuit board 3 are electrically connected. The water dispenser body 1 includes a base 7 and an outer frame 8. The heating element 2 and the circuit board 3 are installed on the base 7 by a fixing bracket. The upper end of the outer frame 8 is also provided with a detachable water inlet 9. The heating element 2 includes a water pipe 201. A dual heating tube assembly 202 is provided on the side of the water pipe 201. The dual heating tube assembly 202 is controlled by a voltage detection and switching module on the circuit board 3.

[0027] Specifically, the dual heating tube assembly 202 includes two hollow pipes 204, which are located on both sides of the water pipe 201 and each pipe 204 is equipped with a heating tube 203. The heating tubes 203 are configured as two heating tubes with different voltages and are installed in the pipes 204 on both sides of the water pipe 201. The dual heating tube assembly 202 can withstand voltages from 100V to 240V and has a minimum power of 900W, making it energy-efficient.

[0028] Ideally, the two heating elements 203 should be configured with one relatively high voltage and one relatively low voltage. The heating elements 203 should be adapted to the power supply voltage of different regions and automatically switched by electrical components. Specifically, the working state is controlled by the voltage detection and switching module built into the water dispenser. When the input voltage is detected to be low, it automatically switches to the first heating element for heating; when the input voltage is detected to be high, it automatically switches to the second heating element for heating. No manual operation by the user is required, ensuring that the equipment can work stably under different voltage environments.

[0029] In addition, its two heating tubes 203 can also be set to heating tubes with the same voltage. By activating the two heating tubes 203 with the same voltage at the same time, the liquid temperature rises faster, thereby increasing the heating speed.

[0030] Furthermore, the water pipe 201 protrudes from the pipes 204 on both sides, and the water pipe 201 and the two pipes 204 are integrally formed. The heating pipe 203 is placed inside the hollow pipe 204.

[0031] Furthermore, the water pipe 201 is made of aluminum, and an auxiliary heat-conducting baffle is provided inside the water pipe 201. The baffle is a raised rib 205 on the inner wall of the water pipe 201. When the liquid enters the water pipe 201, the temperature of the liquid rises through the inner wall of the water pipe 201, thus heating the liquid. The rib 205 increases the contact area and heat conduction area between the liquid and the water pipe 201, making the water flow heat up faster, and also plays a role in diverting the water flow.

[0032] Furthermore, the flow-deflecting element can also be a stainless steel spring placed inside the water pipe 201 to increase water flow resistance, increase the contact area with the water flow, and increase the water flow heating temperature.

[0033] Furthermore, both the water pipe 201 and the pipe 204 have a U-shaped structure. The two ports of the water pipe 201 are higher than the ports of the pipes 204 on both sides. The U-shaped structure reduces the floor space occupied by the heating element 2, allowing it to be better installed inside the water dispenser body 1. In larger water dispensers, the water pipe 201 and the pipe 204 can also be designed as W or S-shaped, thus allowing for better installation inside the water dispenser.

[0034] Furthermore, the water outlet of the water pipe 201 is connected to the water outlet 5 via the water outlet pipe 4. A temperature sensor 6 is connected to the water outlet pipe 4. One end of the temperature sensor 6 is inserted into the inside of the water outlet pipe 4. The temperature sensor 6 is electrically connected to the circuit board 3 via a wire to detect the water temperature.

[0035] This invention, through its dual heating element design and automatic switching, ensures efficient heating under different voltages, meeting users' needs for quick hot water. It is highly adaptable, automatically adapting to the voltage environments of different countries, eliminating the need for cumbersome manual switching by users, and making it convenient for use in different regions.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
