Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to an improved structure of an instantaneous heater. Background Technology

[0002] The existing instant heater, as seen in Chinese Utility Model Patent CN220212665U, entitled "Heating Element Assembly and Instant Water Dispenser Including the Heating Element Assembly," authorized on December 22, 2023, includes a heating element assembly, a heating pipe with an inlet and an outlet, a water distribution base, a motor, and a movable water channel. The water distribution base and motor are respectively located on the heating pipe near the outlet. The motor's output shaft is connected to the movable water channel. The water distribution base has at least two water channels, one end of which is connected to the outlet, and the other end is connected to the corresponding water channel. This heating element assembly, by adding a water distribution base and movable water channels, allows the motor to drive the movable water channel to rotate, enabling heated water to flow through the movable water channel to different water channels on the water distribution base. Different water channels can correspond to different usage needs, such as providing hot drinking water, brewing coffee, or brewing tea. In other words, this heating element assembly can meet various user needs, and its overall operation is simple and convenient, which is conducive to the promotion and application of the product.

[0003] However, the heating tube assembly with the above structure still has the following shortcomings: (1) The above heating pipe is a water pipe covered with a heating film. The lower end outlet of the water pipe is the inlet and the upper end outlet is the outlet. When heating, the boiling force of the water is used to make the hot water boil upward and discharge it from the water pipe. However, the main heating area of ​​the water pipe is concentrated in the area near the side wall of the water pipe. The heating efficiency of the central area of ​​the water pipe is low, which affects the overall heating efficiency of the water pipe. There is also a situation where the water in the center of the water pipe is not fully heated and is carried out of the water pipe by the boiling water in the side wall area of ​​the water pipe, which affects the quality of the hot water. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an improved structure for an instantaneous heater that improves the heating efficiency of the water pipe while ensuring the quality of the hot water.

[0005] The purpose of this utility model is achieved as follows: An improved instantaneous heater structure includes a shell, an instantaneous heating element, and a circuit board. The instantaneous heating element is fixed inside the shell and includes a water pipe and an electric heating element disposed on the outer wall of the water pipe. The electric heating element is electrically connected to the circuit board. The water pipe is characterized by a partition wall dividing its interior into an inner cavity and an outer cavity, with the lower part of the inner cavity communicating with the lower part of the outer cavity. The bottom of the water pipe is closed, and the upper part of the water pipe has an inlet communicating with the inner cavity and a hot water outlet communicating with the outer cavity. In this improved instantaneous heater structure, water entering the inner cavity through the inlet flows through the lower part of the inner cavity to the outer cavity, where it accumulates. The electric heating element then rapidly heats the water in the outer cavity until it boils, and the water is discharged through the hot water outlet from the water pipe. During this process, the electric heating element only needs to heat the water in the outer cavity, reducing the heating volume and allowing the water in the outer cavity to be heated to the set temperature more quickly, improving hot water output efficiency and ensuring good hot water quality.

[0006] The objective of this utility model can also be achieved by the following technical measures: Specifically, the water inlet is located inside the hot water outlet, so that the water inlet and outlet of the water pipe are both realized at its upper part and are independent of each other, without affecting each other, which has a better implementation effect.

[0007] Specifically, a fixed cover is provided at the upper opening of the water pipe, with the water inlet at the center of the fixed cover and several water outlets on the fixed cover, with the water outlets located on the outer periphery of the water inlet, and the water outlets constituting the hot water outlet; both the water inlet and the hot water outlet are located on the fixed cover, which is relatively easy to implement, and the positions of the water inlet and the hot water outlet on the fixed cover are independent, which is conducive to achieving stable water inlet and outlet.

[0008] Specifically, it further includes a water outlet seat, which has a connected water passage recess and a drainage channel. The water passage recess is fitted around the outer periphery of the fixed cover, and there is a water passage space between the water passage recess and the outer wall of the fixed cover. This allows the hot water discharged through the water outlet to pass through the water passage space and the drainage channel in sequence before being discharged. The water outlet seat facilitates the discharge of hot water outside the instantaneous heater.

[0009] Specifically, a fixing post extends from the middle of the fixing cover in the direction of the upper and lower ends. The fixing post has a hollow through hole. The upper end of the fixing post passes through the water outlet seat and the shell, and the lower end of the fixing post extends downward into the inner cavity. The hollow through hole constitutes the water inlet. The upper end of the fixing post facilitates connection with an external water source, and the lower end of the fixing post extending into the inner cavity allows external water to flow directly into the inner cavity.

[0010] Specifically, it further includes an inner tube, the upper end of which is fitted around the lower end of the fixed column located inside the water pipe, and the bottom of the inner tube has several hollow openings. The inner tube constitutes the partition wall. The inner tube has a simple structure and is easy to obtain. At the same time, the hollow opening structure is simple and can well realize the communication between the inner and outer cavities.

[0011] Specifically, it further includes a sealing plug. The water pipe is a hollow tube. The upper part of the sealing plug is fixed to the bottom opening of the water pipe, and the inner circumference of the bottom of the water pipe is press-fitted with the outer circumference of the upper part of the sealing plug. The inner bottom of the housing has a mounting groove, and the lower part of the sealing plug is inserted into the mounting groove. This allows the sealing plug to effectively seal the bottom of the water pipe and achieve bottom closure of the water pipe. Furthermore, the water pipe can also be installed inside the housing through the sealing plug.

[0012] Furthermore, an electric heating film is fixed to the outer end of the water pipe, and an electrode conductive plate electrically connected to the electric heating film is provided on the outer periphery of the water pipe. One end of the electrode conductive plate is electrically connected to the circuit board, and the electric heating film constitutes the electric heating element; so as to realize the electrical connection between the electric heating film and the circuit board, which is relatively simple to implement and has good implementation effect.

[0013] Specifically, one end of the instant heating tube is connected to a water inlet pipe, which includes at least one water inlet pipe, and one end of the water inlet pipe is connected to an external water source; this is relatively easy to implement.

[0014] Specifically, it further includes a water pump and an intermediate box. The water pump is fixed on the outer periphery of the housing, and the intermediate box is placed on the housing and the water pump. The intermediate box is provided with a first connecting cavity and a second connecting cavity. The two ends of the first connecting cavity are respectively connected to the other end of the water inlet pipe and the inlet of the water pump, and the two ends of the second connecting cavity are respectively connected to the outlet of the water pump and the inlet of the water pipe. The water circuit connection between the water inlet pipe, the water pump and the instant heating pipe is realized through the intermediate box, and the implementation effect is good.

[0015] The beneficial effects of this utility model are as follows: (1) This instant heater has an improved structure. Water entering the inner cavity through the inlet flows to the outer cavity through the lower part of the inner cavity. The heating element then heats the water in the outer cavity quickly until it boils and is discharged through the hot water outlet. In this process, the heating element only needs to heat the water in the outer cavity, and the heating volume is reduced, so that the water in the outer cavity can be heated to the set temperature more quickly, improving the hot water output efficiency and ensuring the quality of the hot water.

[0016] (2) Both the water inlet and the hot book outlet are set on the fixed cover, which is relatively easy to implement. The water inlet and the hot book outlet are located independently on the fixed cover, which is conducive to achieving stable water inlet and outlet.

[0017] (3) The water circuit connection between the water inlet pipe, water pump and instant heating pipe is realized through the intermediate box, and the implementation effect is good. Attached Figure Description

[0042] More specifically, it also includes an L-shaped connecting pipe 63, the upper end of which is rotatably fitted around the lower outer periphery of the vertical pipe body.

[0043] More specifically, it also includes a protective cover 40, with elastic hooks 401 extending from the side opening of the protective cover 40.

[0045] In this embodiment, a water pump 8 and an intermediate box 9 are also included. The water pump 8 is fixed on the outer periphery of the housing 1, and the intermediate box 9 is placed on the housing 1 and the water pump 8.

[0048] like Figure 11 The diagram shown is an electrical schematic of this utility model. The infrared detection component 5 includes an infrared emitting tube and an infrared receiving tube. The infrared emitting tube continuously emits a red line into the water inlet pipe 6. When the water flows through the water inlet pipe 6, the water flow will push the floating component to move upward. Both the water flow and the floating component can reflect the red line (the floating component has a better reflection effect), so that the reflected red line is received by the infrared receiving tube. Then the infrared receiving tube outputs a low-level signal to the control module on the circuit board 3, so as to realize the control of the instant heating tube 2 by the circuit board 3 to power on and work. Conversely, when there is no water flow in the inlet pipe 6, the floating part falls to the vicinity of the inlet 65 due to its own gravity. That is, the floating part will not move up, the red line emitted by the infrared emitting tube will not be reflected back, the infrared receiving tube will not receive the red line, and then the infrared receiving tube will output a high-level signal to the control module on the circuit board 3 so as to realize the control of the instant heating tube 2 by the circuit board 3 to cut off the power and realize the anti-dry burning function.

[0049] Infrared detection component 5 is a photocurrent patch manufactured by Yonglin Electronics Co., Ltd., model: YL3528 / WT / P2 / 20-P940 / PT-JC.

[0050] The embodiments described above are merely examples for clearly illustrating this patent, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this patent, and these all fall within the scope of protection of this patent. Therefore, the scope of protection of this patent should be determined by the appended claims.
