CN201926245U - Refrigerator with function of power consumption real-time display - Google Patents

The utility model discloses a refrigerator with the function of power consumption real-time display. A single-phase electric energy metering module is connected to an electric control part to record the electric energy consumed by the refrigerator in actual operation, and the electric energy is displayed through a display device arranged on a case body of the refrigerator. The single-phase electric energy metering module is added to the electric control part of the traditional refrigerator, and the electric energy consumed by the refrigerator in the actual operation is displayed through the display device, so that both the accumulated electric energy consumption of the refrigerator over a period of time and the power consumption in 24 hours can be displayed.

The refrigerator that has real-time demonstration power consumption function

Technical field:

The utility model relates to refrigerator, a kind of refrigerator with real-time demonstration power consumption function of more specifically saying so.

Background technology:

Present domestic energy resources are very limited, consumers in general are when buying refrigerator, all consider the energy conservation characteristic of refrigerator, conventional refrigerator is being sold the embodiment in the efficiency sign of power consumption in time, and the power consumption of this sign is to test to obtain under the state that specific environment, refrigerator doors are not opened, therefore the day power consumption of consumer's actual consumption has no way of finding out about it, and a kind of refrigerator that can actual displayed reflection consumer power consumption need be provided, and allows the more directly operating position of perception oneself of consumer.But present refrigerator does not provide such function.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of refrigerator that consumer demand can show power consumption in real time that meets.

The utility model technical solution problem adopts following technical scheme:

The refrigerator that has real-time demonstration power consumption function adds the single-phase electric energy metering module in the electric control system of described refrigerator, the electric energy that consumes during record refrigerator actual motion also shows by the display unit that is arranged on the refrigerator.

Design feature of the present utility model also is:

This section of the every fixed interval Time Calculation of refrigerator control chip time loss electric energy, 24h power consumption calculates by the electric energy in the Fixed Time Interval.

Give on the refrigerator load power supply circuits at power supply, the minimum resistance R 1 (μ Ω level) of series connection resistance, described single-phase electric energy metering module detects R1 and goes up voltage, through after the processing of electric energy computation chip digital signal processing circuit the energy data of load consumption being exported with pulse signal, described pulse signal is delivered to refrigerator master control borad single-chip processor i/o mouth by optocoupler.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, in the electric control system of conventional refrigerator, add the single-phase electric energy metering module, the electric energy that consumes during the refrigerator actual motion shows by display unit, can add up electric energy and 24 hours power consumption of consuming display refrigerator a period of time.

2, show by automatic switching mode or manual switchover mode: the preceding 24 hours power consumption of refrigerator when consumed power that refrigerator is total and switching show; Refrigerator shows increases new content, enriches product function, improves product competitiveness, for life offers convenience; Accurately, reflect the power save parameters that the consumer is concerned about in real time.

Description of drawings:

Fig. 1 is a kind of electric control system module map among the utility model embodiment.

Fig. 2 is a kind of displaying scheme among the utility model embodiment.

Number in the figure: 1 shows that refrigerated storage temperature charactron, 2 shows that cryogenic temperature charactron, 3 shows that power consumption charactron, 4 buttons, 5 show the power consumption unit cell pattern.

Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

The specific embodiment:

Embodiment: referring to Fig. 1, L is a refrigerator power line live wire end among the figure, N is a zero line side, give on the refrigerator load power supply circuits at power supply, the minimum resistance R 1 (μ Ω level) of series connection resistance, the single-phase electric energy metering module detects upward voltage of R1, handles through the electric energy computation chip digital signal processing circuit, finally makes the energy data of load consumption export with the signal of a kind of pulse (as CF end output pulse among Fig. 1) form.In order to reach the purpose of isolation, adopted the photoelectricity isolation during output of CF end, pulse signal is delivered to master control borad single-chip processor i/o mouth by optocoupler.

The master control borad single-chip microcomputer carries out Fixed Time Interval by the pulse signal to CF output and detects, simultaneously:

A, timer, register are set, record CF end output pulse total quantity and 24h number of pulses;

B, according to the ammeter constant that the electric energy metrical module is provided with, for example the ammeter constant is: 3200imp/kwh (i.e. 1 degree is represented in 3200 pulses), the umber of pulse that writes down among the A is converted to electric energy, promptly get refrigerator and add up the electric energy of consumption and the electric energy of 24h consumption.Master control borad send the energy data that obtains display board to show at last.

A, when normally moving, display board shows refrigerated storage temperature, cryogenic temperature; Power consumption viewing area charactron and pattern are not lighted.

Above disclosed only is a kind of embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
