Description

Delay control system of oven fan

Technical Field

The utility model relates to an oven equipment, concretely relates to oven fan's time delay control system.

Background

At present, more and more families and merchants begin to process food by adopting an oven, and people can make various baked and baked foods by utilizing the oven. Wherein, comparatively high-end oven often is equipped with convection current fan and protection fan, inside convection current fan mainly used blows the fan of heat source to the oven for the inside temperature of oven is even, the protection fan mainly is in order to prevent that computer version temperature is too high and outwards get rid of hot-blast reduction PCB board ambient temperature, after the oven circular telegram starts, the action of meeting synchronous control fan, after the oven outage, then the meeting synchronous control fan is closed, the defect that the control method who adopts this kind of fan exists is: when the oven outage back, the oven is inside still can have a large amount of steam, leads to the food in the oven to be burnt by excessively, influences the quality of food, opens the oven door in addition, and steam can be gone outward and gush out, probably causes the scald to the human body, and the security is also relatively poor.

Disclosure of Invention

In view of the not enough of background art, the utility model aims to solve the technical problem that a simple structure is provided, reasonable in design can realize the inside cooling heat dissipation of barbecue machine for the barbecue machine carries out the operation in a suitable temperature range, ensures the steady operation of barbecue machine, and effectively promotes the time delay control system of the oven fan of the life of barbecue machine.

Therefore, the utility model discloses an adopt following scheme to realize:

oven fan's time delay control system, its characterized in that: the automatic control system comprises an alternating current power supply module, a first switch module, a second switch module, a third switch module, a load control module and a timing control module, wherein the load control module and the timing control module are used for controlling the opening and closing of a fan, the first switch module, the second switch module and the third switch module are respectively and correspondingly electrically connected with a plurality of control switches arranged outside an oven, the alternating current power supply module is electrically connected with the first switch module, the second switch module and the third switch module, the first switch module, the second switch module and the third switch module are electrically connected with the load control module, the alternating current power supply module is electrically connected with the timing control module, the positioning control module is electrically connected with the load control module.

And a voltage reduction rectification module is arranged between the alternating current power supply module and the timing control module.

The timing control module is in an active state after being powered on for at least five seconds.

Adopt above-mentioned technical scheme, the utility model discloses an advantage does: the user only needs to press the control switch of oven peripheral hardware according to the user demand and starts the oven, the switch module that corresponds this moment also can switch on, and transmission signal drives the fan function for load control module, after reaching predetermined barbecue time, the control switch of oven peripheral hardware closes, the switch module that corresponds also can break off, timing control module accepts the signal and begins the timing this moment, and control load control module continues work and drives the fan function, thereby discharge the steam in the oven, the inside food of protection oven can not burnt by excessive roast, effectively promote the food quality after the baking, also avoided having a large amount of steam to gush out after opening the oven door simultaneously, play the guard action to the user, avoid the user to be scalded by steam.

Drawings

The utility model discloses there is following figure:

fig. 1 is a schematic block diagram of the present invention.

Detailed Description

As shown in the figure, the utility model discloses a time delay control system of oven fan, including the AC power supply module, first switch module, the second switch module, the third switch module, a load control module and timing control module for controlling the fan and open and close, it is first, second and third switch module correspond respectively and are connected with a plurality of control switch electricity of oven peripheral hardware, the AC power supply module is with first, second and third switch module electricity are connected, it is first, second and third switch module are connected with load control module electricity, the AC power supply module is connected with timing control module electricity, positioning control module is connected with load control module electricity, load control module is connected with the fan electricity. The user only needs to press the control switch of oven peripheral hardware according to the user demand and starts the oven, the switch module that corresponds this moment also can switch on, and transmission signal drives the fan function for load control module, after reaching predetermined barbecue time, the control switch of oven peripheral hardware closes, the switch module that corresponds also can break off, timing control module received the signal this moment and started the count down of 10 minutes, and control load control module continues work and drives fan function 10 minutes, thereby discharge the steam in the oven, the inside food of protection oven can not burnt by excessive roast, effectively promote the food quality after the baking, also avoided opening oven door simultaneously and then have a large amount of steam to gush out, play the guard action to the user, avoid the user to be scalded by steam. A voltage reduction rectification module is arranged between the alternating current power supply module and the timing control module, so that the timing control module can safely and smoothly receive an electric signal. The timing control module is in an activated state after being electrified for at least five seconds, and when the condition that a user turns on a switch of the peripheral equipment by misoperation and then turns off the switch immediately occurs, the timing control module cannot be activated, so that the condition that the draught fan cannot run idle is ensured.
