Abstract

The utility model relates to a refrigerator with the door-opening voice prompting function, comprising a voice prompting circuit module and a travel switch. The voice prompting circuit module is formed by a stabilized voltage power supply circuit, a voice chip circuit and a buzzer and is sealed in a shell; the anode of the output end of the stabilized voltage power supply circuit is connected in series with the normally closed contact of the travel switch; the stabilized voltage power supply circuit supplies power to the voice chip circuit through the travel switch; the travel switch is arranged on the side surface of the inner wall of the refrigerator; when the door of the refrigerator is opened, the normally closed contact of the travel switch is popped and closed, and the anode of the input end of the power supply of the voice chip circuit is connected and energized so that the voice chip circuit works and makes a voice prompt sound; and the voice prompting circuit module has the advantages of simple structure, low manufacturing cost and easy control and use, and can be widely applied to the refrigerator.

Description

Refrigerator with spacious door sound prompt function

Technical field

The utility model relates to refrigerator, particularly a kind of refrigerator that can send the spacious door sound prompt function of having of voice suggestion when refrigerator doors does not shut automatically.

Background technology

The refrigerator technology is very ripe at present, and is various multiple functional, and the particularly existing development of refrigerator aspect power-saving technology is more outstanding, and not only quality is good to produce refrigerator product, refrigerating efficiency high and also consume energy low, very economize on electricity; Yet, the electric energy that energy-conservation product is saved, sometimes but offset by artificial negligence, for example, open and but forgotten the pass refrigerator doors after refrigerator doors has been got thing, and the household also is absent from the scene, cause compressor for refrigeration length to be in open state often, in this case, the performance of refrigerator product has not been energy-conservation principal element, and how to avoid above-mentioned human factor to cause energy dissipation to become the key of problem, as and if this situation has all been ignored by refrigerator manufacturer, do not have also that refrigerator is additional to have reminds people to get the device that shuts the function of refrigerator doors behind the thing.

Summary of the invention

In view of the prior art above shortcomings, the utility model provides a kind of refrigerator that can send the spacious door sound prompt function of having of voice suggestion user when refrigerator doors does not shut automatically.

The technical scheme that the utility model is taked for achieving the above object is: the refrigerator with spacious door sound prompt function, comprise voice warning circuit module and travel switch, it is characterized in that, the voice warning circuit module comprises that voltage-stabilized power supply circuit, sound chip circuit, buzzer constitute, be sealed in the casing, the output head anode of voltage-stabilized power supply circuit is connected in series described travel switch normally-closed contact, provides power supply through travel switch for sound chip circuit; Travel switch is installed in refrigerator inwall side near the refrigerator doors position, and when refrigerator doors was opened wide, the travel switch contact was in ejection state (switch contact closure); When refrigerator doors was closed, the travel switch contact is in compressed into the disconnection of status switch contact.

Adopt above-mentioned voice warning circuit module, can adopt and to carry out the one-off programming speech chip, the voice programming software operation is simple, multiple functional, can shorten the fabrication cycle of chip greatly, and dependable performance, make full use of the resource of chip internal, the one-off programming speech chip is carried out in employing, can not only realize the control mode of standard, also can be according to customer demand, tailor-made various functions, this voice warning circuit module has that circuit structure is simple, cost is low, control and use characteristic of simple easily, can be widely used in the refrigerator

Thereby make refrigerator product not only energy-conservation on performance, and consider in the product use,, make product hommization more in design because human factor causes the possibility of energy dissipation.

Description of drawings

Fig. 1 the utility model circuit connects block diagram, and as Figure of abstract;

Fig. 2 travel switch contact state schematic diagram.

The specific embodiment

As shown in Figure 1, have the refrigerator of spacious door sound prompt function, comprise voice warning circuit module 1 and travel switch 2, voice warning circuit module 1 comprises that voltage-stabilized power supply circuit 11, sound chip circuit 12, buzzer 13 constitute, be sealed in the casing, casing can be fixed on the back side of refrigerator.

Voltage-stabilized power supply circuit 11 outputs are drawn lead, anodal serial connection travel switch normally-closed contact, insert from a terminal contacts, draw through travel switch 2 other end contacts, connect sound chip circuit 12 power input positive poles, voltage-stabilized power supply circuit 11 negative pole of output end directly connect sound chip circuit 12 power input negative poles, for sound chip circuit 12 provides power supply.

As shown in Figure 2, travel switch 2 is installed in refrigerator inwall side near the refrigerator doors position, and when refrigerator doors was opened wide, travel switch 2 contacts were in ejection state (switch contact closure); At this moment, it is electricly anodal to connect sound chip circuit 12 power inputs, and the voice suggestion sound is sent in sound chip circuit 12 work.

When refrigerator doors was closed, travel switch 2 contacts were in the state of compressing into (switch contact disconnection); Connect the anodal dead electricity of sound chip circuit 12 power inputs, sound chip circuit 12 is not worked.

Claims

1, a kind of refrigerator with spacious door sound prompt function, comprise voice warning circuit module (1) and travel switch (2), it is characterized in that, voice warning circuit module (1) comprises that voltage-stabilized power supply circuit (11), sound chip circuit (12), buzzer (13) constitute, be sealed in the casing, the output head anode of voltage-stabilized power supply circuit (11) is connected in series described travel switch (2) normally-closed contact, provides power supply through travel switch (2) for sound chip circuit (12); Travel switch (2) is installed in refrigerator inwall side near the refrigerator doors position.
