Description

Technical Field

[0001] This utility model relates to the field of drinking water heating technology, and in particular to an integrated heating module for drinking water equipment. Background Technology

[0002] Instantaneous heating modules are now widely used in household appliances such as water dispensers and water purifiers. They eliminate the need for pre-boiling water and long waiting times, providing instant heating and great convenience to consumers. An instantaneous heating module consists of a water pump, a heating element assembly, and an inlet water temperature control probe. In existing heating module structures, the water pump, heating element assembly, and inlet water temperature control probe are often connected via silicone tee fittings and secured with cable ties. However, this connection method has the following drawbacks: 1. The silicone tee fittings at the connection points have poor pressure resistance; 2. The assembly of the silicone tee fittings is cumbersome, requiring the three components to be connected first, followed by cable ties for reinforcement. Furthermore, the small size of the heating element assembly makes cable ties difficult to apply. Utility Model Content

This module integrates the inlet water temperature control probe with the water pump, and connects the outlet pipe of the water pump with the inlet pipe of the heating element assembly via a quick-connect method. This makes the overall structure more compact and stable, eliminates the need for silicone tees, and solves the problems of poor pressure resistance and complicated assembly at the connection.

[0004] To achieve the above objectives, this utility model provides an integrated heating module for a drinking water device, including a water pump, a heating element assembly, and an inlet water temperature control probe. The heating element assembly includes a rigid inlet pipe used as a quick-connect rod.

[0005] The outlet pipe is further configured such that its inner cavity includes a first pipe, a second pipe, and a third pipe that extend coaxially and whose diameter gradually decreases from the outside to the inside.

[0006] The diameter of the inlet pipe is adapted to the inner diameter of the second pipe. The inlet pipe is equipped with an inner claw quick connector for fastening into the first pipe. The inlet water temperature control probe is installed at the third pipe of the outlet pipe.

[0007] A further provision is made: a sealing ring is provided inside the first pipe of the outlet pipe for the inlet pipe to pass through in order to seal the gap between the two.

[0008] The heating element assembly is further configured as follows: the heating element assembly includes a heating tube, an inlet end cap and an outlet end cap respectively covering the two ends of the heating tube, and a heating electrode with one end sleeved on the heating tube and the other end connected to an external power source. The inlet tube is a plastic tube inserted into the interface of the outlet end cap or is part of the interface of the outlet end cap.

[0009] The heating element assembly is further configured to include a housing disposed outside the heating tube, the housing comprising two constraint members disposed outside the inlet end cap and the outlet end cap respectively, and at least one connecting member connected between the two constraint members.

[0010] The water inlet cap and the water outlet cap each include a cap body portion that is sleeved on the port of the heating tube, and an interface portion connected to the sleeve portion, wherein the water inlet tube is inserted into the interface portion of the water inlet cap.

[0011] Each of the aforementioned constraint members includes a U-shaped frame that is fitted onto the interface portion and presses against the cover portion;

[0012] The connecting component is a U-shaped groove, which is fitted onto the ends of the two U-shaped frames and is fixedly connected to each other by screws.

[0023] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0024] This utility model discloses an integrated heating module for a drinking water device, such as... Figure 1 As shown, the device includes a heating element assembly 10, a water pump 20, an inlet water temperature control probe 22, and an outlet water temperature control probe 17. The heating element assembly 10 has an inlet pipe 15 and an outlet pipe 16 at its two ends. The outlet water temperature control probe 17 is mounted on the outlet pipe 16 of the heating element assembly 10 to detect the temperature of the flowing water. The inlet pipe 15 is a rigid plastic tube used as a quick-connect fitting. The water pump 20 has an outlet pipe 21 with a rigid plastic tube structure. The inner cavity of the outlet pipe 21 is configured as a quick-connect interface for quick-connect fitting with the inlet pipe 15. The structure features an inlet water temperature control probe 22 positioned on the outlet pipe 21 inside the quick-connect position of the inlet pipe 15 to detect the temperature of the flowing water. By directly placing the inlet water temperature control probe 22 on the outlet pipe 21 of the water pump 20, the two are combined to form a water pump 20 with a temperature control probe. At the same time, the water pump 20 and the heating element assembly 10 are quickly connected by inserting the inlet pipe 15 and the outlet pipe 21, eliminating the need for traditional silicone tees and thus solving the problems of poor pressure resistance and complicated assembly at the connection.

[0025] In this embodiment, as shown in Figure 2 and Figure 3As shown, the inner cavity of the outlet pipe 21 of the water pump 20 includes a first pipe 211, a second pipe 212, and a third pipe 213 that extend coaxially and whose diameters gradually decrease from the outside to the inside (relative to the flow direction from back to front). The diameter of the inlet pipe 15 is adapted to the inner diameter of the first pipe 211. The inlet pipe 15 is provided with an inner claw quick connector 151 for fastening to the first pipe 211 to fix the two together. The inlet water temperature control probe 22 is located at the third pipe 213 of the outlet pipe 21. At the same time, in order to ensure the sealing effect between the inlet pipe 15 and the outlet pipe 21, it is preferable that a sealing ring 214 is provided in the first pipe 211 of the outlet pipe 21 for the inlet pipe 15 to pass through to seal the gap between the two.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the heating element assembly 10 includes a housing 18 and a heating element extending axially within the housing 18. The heating element includes a PTC ceramic heating tube 11, an inlet cap 12 and an outlet cap 13 respectively covering the two ends of the heating tube 11, and a heating electrode 14 with one end sleeved on the heating tube 11 and the other end connected to an external power source. The inlet cap 12 and the outlet cap 13 each include a cover portion 121 sleeved on the port of the heating tube 11 and an interface portion 122 connected to the sleeve portion. The inlet pipe 15 and the outlet end are respectively fixedly inserted into the interface portion 122 of the inlet cap 12 and the outlet cap 13. Preferably, the inner wall of the interface portion 122 is provided with several sealing ribs. In some other specific embodiments, the outlet pipe 16 and the inlet pipe 15 may also be part of the interface portion 122.

[0027] In this embodiment, as Figure 4 As shown, the outer casing 18 includes constraint members 181 respectively disposed on the outside of the inlet and outlet end caps 13 at both ends, and a connecting member 182 connecting the two constraint members 181. The constraint members 181 at both ends of the outer casing 18 are used to clamp and constrain the inlet and outlet end caps 13 at both ends so that the end caps are securely installed on the heating pipe 11. The connecting member 182 is used to tighten the constraint members 181 at both ends.

[0028] In the above scheme, such as Figure 3 and Figure 4As shown, the constraint member 181 includes a U-shaped frame 1811 fitted onto the interface portion 122 of the end cap and pressing against the cover portion 121, and a blocking member 1812 connected between the two sides of the opening of the U-shaped frame 1811 and pressing against the end of the interface portion 122. Thus, the constraint member 181 can better constrain the end cap. The connecting member 182 is a U-shaped groove. The connecting member 182 is arranged horizontally on one side of the heating body, and the ends of both end caps are placed in the groove of the connecting member 182. The side wall of the U-shaped frame 1811 and the side wall of the connecting member 182 are fastened together by screws. Thus, under the tension of the connecting member 182, the constraint members 181 at both ends can firmly clamp the end cap. Preferably, there are two connecting members 182, which are arranged facing each other on opposite sides of the heating body to achieve encirclement, which can protect the internal heating body.

[0029] Compared with the prior art, this utility model has a simple and reasonable structure, integrating the inlet water temperature control probe and the water pump into one unit, reducing the use of fixing devices, making the structure more compact and improving production efficiency; at the same time, the outlet pipe of the water pump and the inlet pipe of the heating element assembly are connected by a quick-connect method, further improving the compactness and stability of the overall structure, eliminating the need for silicone tee structure, thus solving the problems of poor pressure bearing capacity and troublesome assembly at the connection.

[0030] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
