Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like figure 1 As shown, the numerically controlled constant temperature water delivery device of the present invention is respectively connected to the manipulator, display, temperature collector and numerically controlled driver through the CPU interface, and the mechanical water mixing device is respectively connected to the temperature collector and numerically controlled driver.

[0020] Described CPU is made up of 8 or 16 single-chip microcomputers. This embodiment selects AT89C51 one-chip computer in MCS-51 series for use. The single-chip microcomputer ports can be allocated and used arbitrarily. The allocation method of this embodiment is as follows: the 8-bit I / O interface of the P0 port is connected to the signal input terminal of the numerical control drive circuit, and the 0-3 bits control the stepper motor installed in the mechanical water mixing de...

Abstract

The numerically controlled constant-temperature water conveying device is one device to make water heater output constant-temperature hot water. The technological scheme includes connecting CPU to operating unit, display, temperature collector and numerically controlled driver; and connecting the mechanical water mixer to the temperature collector and the numerically controlled driver. The temperature collector consists of non-shielded anti-jamming amplifier, temperature sensor connected to the input of the amplifier and A / D converter connected to the output of the amplifier. The mechanical water mixer consists of water mixing seat, water mixing chamber, cold water inputting controller and hot water inputting controller. The present invention has the functions of controlling the temperature of the electric water heater and outputting constant-temperature hot water, and may be used to replace available electric control board.

Description

technical field [0001] The invention relates to a water delivery device, more specifically, it relates to a numerically controlled constant temperature water delivery device for an electric water heater. technical background [0002] Although the current commercially available electric water heaters can set the temperature between 30 degrees Celsius and 80 degrees Celsius, they cannot output hot water at a constant temperature stably. Especially when using in winter, this problem is just more prominent. In order to meet the needs of using constant temperature hot water, users often need to manually adjust the cold and hot water valves several times. Therefore, there are many inconveniences in the prior art: (1) manual adjustment is difficult to maintain a constant temperature; (2) when the electric water heater is used continuously, its water temperature will become lower and lower, and it needs to be readjusted, which is troublesome to ...
