Description

Technical Field

[0001] This utility model relates to the field of heat pump water heater technology, specifically to a structural design of a heat pump water heater control panel, which is suitable for large heat pump water heater equipment that requires high stability and efficient maintenance. Background Technology

[0002] As a highly efficient and energy-saving hot water supply device, the control panel of a heat pump water heater, as the core component for user interaction, needs to possess good stability, convenience, and aesthetics. Currently, most control panels on the market use screw fixing or simple clip connections. However, screw fixing has problems such as cumbersome installation steps and inconvenient disassembly and assembly during maintenance, significantly increasing time costs, especially in scenarios with frequent maintenance; while traditional clip structures, due to their simple design, are prone to loosening or falling off in long-term vibration environments, making it difficult to withstand the continuous mechanical vibration of the heat pump water heater during operation, resulting in insufficient stability of the control panel, affecting user experience and equipment safety.

[0003] Furthermore, large heat pump water heaters are typically used in commercial or industrial environments, where the vibrations generated during operation are more significant, placing higher demands on the mounting method of the control panel. Therefore, there is an urgent need for a new type of heat pump water heater control panel that, while ensuring convenient installation and maintenance efficiency, improves the stability of the connection between the panel and the base through optimized structural design, effectively resists operational vibrations, and also maintains a pleasing overall appearance. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A heat pump water heater control panel includes a base, an interface, and a card plate. The base has symmetrical slots along the center line on its upper edge. The number of slots can be set as needed. Each slot has a protrusion above it to form a first positioning groove. The back of the interface has a first positioning protrusion that matches the first positioning groove.

[0006] The base has symmetrical slots along the center line of the left and right sides. The number of slots can be set as needed. Each slot has a protrusion above it with a notch facing the top of the base, forming a second positioning groove. The back of the operating interface has a second positioning protrusion that matches the second positioning groove, so that the second positioning protrusion fits into the notch of the second positioning groove.

[0007] The base has a third positioning slot symmetrically opened along the center line of the lower edge. The number of slots can also be set as needed. The back of the operation interface is provided with an elastic claw that is interference-fitted with the third positioning slot to prevent the operation interface from falling downward.

[0008] The base has a slot at the bottom center and a protrusion above it. The protrusion has a guide groove. The bottom center of the back of the operating interface has a third outward positioning protrusion that slides with the guide groove to position the bottom of the operating interface.

[0009] The base and the operating interface both have notches on the left and right sides near the bottom of the back, forming a snap-fit ​​groove. When the base and the operating interface are fastened together, the snap-fit ​​grooves of the two are aligned vertically.

[0010] The card plate is a U-shaped body with inward card plate protrusions on both sides. The card plate protrusions are inserted into the slots of the base and the operation interface to further fix the base and the operation panel.

[0011] Preferably, after the card plate is fully inserted into the slot groove of the base and the operating interface, its U-shaped body completely wraps around the bottom edge of the base and the operating interface, and forms a seamless connection with the bottom of the base and the operating interface.

[0012] Preferably, a guide slope is provided on the side near the opening of the first positioning groove to guide the sliding of the elastic hook structure.

[0013] Preferably, the base and the operating interface are arc-shaped, and the base fits into the arc-shaped shell of the water heater and is fixed by bolts.

[0014] Preferably, the first positioning groove has a pair.

[0015] Preferably, the second positioning groove has two pairs.

[0016] Preferably, a pair of third positioning slots are provided.

[0017] Preferably, the center of the base is recessed inward to form a recessed area for placing the control circuitry of the operating interface.

[0018] The above technical solution achieves a more stable connection between the operating interface and the base, effectively preventing the instability of the operating interface caused by continuous mechanical vibration during the operation of large water heaters such as heat pump water heaters. This invention also makes the installation and disassembly of the operating interface and base plate more convenient, improving assembly efficiency, simplifying the maintenance process, and enhancing practicality. Furthermore, the bottom of this invention uses a retaining plate to further secure the operating interface and base plate while maintaining the overall aesthetic appeal of the control panel.

Its U-shaped body completely covers the bottom edge of the base 1 and the operation interface 2, and forms a seamless connection with the bottom of the base 1 and the operation interface 2, and further fixes the base 1 and the operation interface.

[0032] The first positioning groove 11 has a guide slope on one side of the groove opening to guide the elastic hook structure 21 to slide in.

[0033] The base 1 and the operating interface 2 are arc-shaped, fitting snugly against the arc-shaped shell of the heat pump water heater, and are fixed with bolts.

[0034] The center of the base 1 is recessed inward to form a recessed area, which is used to place the control circuit of the operation interface 2.

[0035] When using this utility model, firstly, the base 1 is fixed to the outer surface of the arc-shaped shell of the heat pump water heater with bolts. Then, the top of the operation interface is fixed by the cooperation between the first positioning groove 11 on the base 1 and the first positioning protrusion 21 on the operation interface 2. The left and right sides of the operation interface are fixed by the cooperation between the second positioning protrusion 22 on the operation interface 2 and the second positioning groove 12 on the base 1. The bottom of the operation interface is fixed by the snap-fit ​​connection between the third positioning slot 13 and the elastic claw 23, and the cooperation between the guide groove 14 and the third positioning protrusion 24. Finally, the clip plate 3 is fastened to further fix the operation interface 2 and the base plate 1, and the overall aesthetics of the operation panel are maintained.
