Abstract

The utility model relates to a steaming boiling point and timed monitor for food for monitoring and controlling the steaming boiling point and time for the food (and boiled water). The monitor sends out the sound signal when reaching the point or the set time, and an electric furnace can cut off the power automatically to obtain the effect of saving the time, ensuring the food quality and saving the energy. The monitor is composed of sensing devices arranged on a pot (or a kettle) cover, a monitoring device arranged in the position for the convenience of monitoring and connecting wires. A plurality of sensing devices can use one monitoring device commonly (at different time). When the monitoring is not needed, a plug on the sensing devices is taken off to be used as a common pot cover.

Description

Steaming boiling point and timed monitor for food

The utility model belongs to temperature-electric weight sensing and timing monitoring technique field.

In the family, boil water, cook rice gruel, food such as cooking rice, steamed stuffed bun, steamed bun, meat is the work that all will carry out every day.At present, to the supervision of aforesaid operations process and control entirely by manually finishing.Therefore, when negligence being arranged slightly or being busy with other thing, situations such as water dryouies, meat is burnt just may take place.

The device that the utility model provides a kind of food boiling boiling point and regularly monitors.It is made up of Sensitive Apparatus (1), monitoring device (2) and connection lead (3), as shown in Figure 1.Sensitive Apparatus (1) is installed in pot cover (or pot lid) and goes up the original position that knob is installed.Monitoring device is placed on the place of being convenient to monitor away from the kitchen.When the temperature of the food of water that burns and boiling reached boiling point, this device sent acoustic signal automatically, and reminds people is noted; To the food of needs timing boiling, go up setting-up time by the people at monitoring device (2), when reaching Preset Time, this device sends acoustic signal once more, and expression food is cooked.To using the situation of various electric furnaces, this device will be cut off the electricity supply automatically this moment.

The utility model is designed to the product of two kinds of models.

I type: only food boiling boiling point and timing are monitored not have control function automatically.Be applicable to the stove that uses liquefied gas, natural gas, coal.The theory structure of I type as shown in Figure 2.Now as follows to each part division:

Sensitive Apparatus (1): form by protective sleeve (4), temperature element (5), tight split nut (6), (7), knob (8), button lid (9), fixed head (10), tubular socket (11), plug (12).Its profile is similar to the pot cover knob that generally uses at present.In the time will using this watch-dog, knob lid (9) exposes two jacks, inserts plug (12) and gets final product.When without this watch-dog, take off plug (12), knob lid (9) is with the jack capping.At this moment, have the just the same use of pot cover (or pot lid) of Sensitive Apparatus (1) with common pot cover (or pot lid).

Monitoring device (2): be composed in series by dc source (13), timer (14), integrated circuit musical film (15), loudspeaker (16).When boiling temperature reaches boiling point, send acoustic signal.Timer (14) has a normally closed contact, and behind setting-up time, its normally closed contact disconnects; When reaching the closed again circuit of connecting of its contact of Preset Time, send acoustic signal.

Connect lead (3): adopt very thin lead can satisfy circuit requirement.But consider to adopt the slightly slightly stranded conductor of any from mechanical strength.Should there be the protective layer of several centimeter length the plug of lead and Sensitive Apparatus (12) junction, and the one, prevent from that lead from hanging down on the pot cover to be scorched; The 2nd, avoid lead to fracture in the junction.

II type:, also have the timing controlled function except that having to food boiling boiling point and the function for monitoring regularly.Be applicable to the situation of using electric furnace.The Sensitive Apparatus of II type is identical with the I type.Fig. 3 draws, and (figure a) and main control circuit (scheme b) for its theory structure of surveillance device.

Monitoring device is made up of dc source (13), button (18), timer (14), midget universal relay (17), integrated circuit musical film (15), loudspeaker (16), auxiliary reclay (19).When boiling temperature reached boiling point, 3 volts of DC currents were by midget universal relay J ₁(17) normally closed contact J ₁₁Constitute the loop, send acoustic signal.Locate off-state, J because of button (18) this moment ₁Coil is not charged, so main control circuit is failure to actuate.After using timer (14) setting-up time (its normally closed contact disconnects), push button (18), if digestion time reaches Preset Time, it is closed that the contact of timer (14) recovers.This moment, 6 volts of DC circuits were connected, and sent acoustic signal, simultaneously midget universal relay J ₁(17) coil is charged, its normal opened contact J ₁₂Closure, 220 volts of alternating currents are by auxiliary reclay J ₂(19) coil makes its normally closed contact J ₂Disconnect, the control function is finished in electric furnace (20) outage.

Several Sensitive Apparatuses can be at the public monitoring device of different time.

The utility model can be finished above-mentioned design function through overtesting.

Use advantage of the present utility model and effect to be:

1, saves time.In above-mentioned food digestion process, people can absorbedly do other thing, the digestion process of needn't diverting one's attention to monitor.

2, guarantee food quality.Can prevent that food (particularly meat) is burnt; Drinking water increases because of the long wherein concentration of narmful substance of boiling time; Situations such as food does not cook or digestion time is long take place, thereby have guaranteed the quality of food.

3, fuel or electric energy have been saved.
