Description

Technical Field

[0001] This invention relates to the field of water heater technology, specifically to a plate-shaped instantaneous water heater for smart homes. Background Technology

[0002] A water heater is a device that uses various physical principles to raise the temperature of cold water to hot water within a certain time. Based on different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic water heaters, air source water heaters, and central heating water heaters, etc. Currently, most wall-mounted water heaters are cylindrical storage-type water heaters, which are large, take up a lot of space, and are heavy and difficult to move. Therefore, many plate-type water heaters have emerged, which provide instant heating. However, existing plate-type water heaters often use electric heating elements for heating, which are slow to heat and produce less water. Furthermore, prolonged use leads to scale buildup that is difficult to clean, shortening their lifespan. Therefore, a smart home plate-type instant water heater has been designed.

A heat-conducting steel sheet 25 is fixedly mounted on the second fixing seat, and a heat-conducting rod is provided at one end of the heat-conducting steel sheet 25. The heat-conducting rod penetrates the explosion-proof inner liner 11 and fits against the diversion liner 13.

[0038] As a preferred option, the water inlet 24 on the upper wall of the diversion liner 13 is used as the water inlet, and the water outlet 24 on the lower wall is used as the water outlet. This is designed to meet usage requirements, so that one end of the temperature detector 29 is used to detect the water outlet temperature.

[0039] As a preferred option, the three regions within the diversion liner 13 are alternately connected at one end to form a reciprocating flow, which is used to design the cold water flow path requirements and improve the heat absorption time to achieve rapid heating.

[0040] As a preferred option, the plate heat exchanger's slot 7 can be detachably mounted on the descaling plate 142 to meet design and installation requirements.

[0041] As a preferred option, the outer casing 21 can be hung horizontally with the water inlet 24 facing upwards to meet design and installation requirements, facilitating cold water circulation and promoting heating effect.

[0042] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0043] The working principle is as follows:

[0044] First, by connecting and installing the outer shell 21, bottom cover 22, and sealing cover 23 in the protective structure 2, the heating structure 1 is protected inside, and the equipment can be hung on the wall with force; then, the inlet pipe and outlet pipe are connected by two water nozzles 24 respectively, and the equipment is powered on by the power connector 30.

[0045] Cold water passes through a water nozzle 24, through the flow hole 8 of the outer shell 21, the first transition hole 4 of the explosion-proof inner liner 11, and the second transition hole 5 of the diversion liner 13, and enters the diversion liner 13. Through the opening of the distribution hole, the cold water is quickly sprayed onto both sides of the plate heater 15 in the heating structure 1. The cold water can also flow through the descaling plate 142 in the descaling unit 14 of the limiting plate heater 15. The descaling unit 14 alternately separates the connected areas of the diversion liner 13, allowing the cold water to flow back and forth multiple times, increasing the contact time with the plate heater 15 and improving the rapid heating effect.

[0046] Then hot water can flow out from another water tap 24 near the temperature detector 29. During operation, the internal structure is isolated by the heat insulation layer 12 to protect the internal water temperature and save heat loss. The overall structure is more compact and reduces the space occupied.

[0047] Secondly, by connecting the first switch 26 in series with the second switch 28 on the assembly base 27, the overall safety protection is improved. With the help of the heat-conducting steel sheet 25, the internal dry burning is prevented. In the event of excessive temperature, the power can be cut off. During use, the control box and temperature detector 29 are used to set a constant temperature.

[0048] Finally, after prolonged use, the sealing cover 23 can be removed, and the diversion liner 13 can be removed from the explosion-proof inner tank 11. Then, the descaling plate 142 and the descaling tray 143 can be removed in sequence to remove the scale that has settled at an angle. After the descaling plate 142 is removed from the slot 7 of the plate heater 15, the plate heater 15 can be removed for surface cleaning and maintenance to improve the service life and heating effect of the equipment.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
