Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a so-called range that is integrated with a stove, a gas stove, etc., which is incorporated into a system kitchen or the like.

Conventional technology These days, many large building jaw rooms are not permitted to have gas intake pipes. Therefore,
without connecting the gas intake pipe to the primary gas piping of the range.
I try to explain the product by plugging only the power supply cable into a commercial power source, but the safety circuit (misfire detection circuit, etc.) activates and the device turns off completely.

In addition, for general consumers and families with small children,
A child's mischief may cause the microwave to be operated without permission, causing food to burn, or causing the device to operate without food, compromising the safety of the device. The durability of the product was impaired.

Problems to be Solved by the Invention Therefore, in such a microwave oven, it was not possible to explain the product of the appliance to the purchaser of the appliance in a place where the gas intake pipe of the jaw room of a large building was not permitted. . Therefore, product explanations for complex appliances such as stoves, fish grills, open grills, etc. have to be done through catalogs and flyers, and there is a problem in that it is very difficult to explain the products themselves. However, in households where there are small children and general consumers, the child may play a trick and operate the appliance without permission, causing all of the food to be burned, or causing the appliance to operate without any food being cooked. The problem is that it is very difficult to eliminate these problems because the safety of the equipment is compromised and the durability of the equipment is compromised.

The present invention solves these conventional problems, and allows the product to be operated and explained in the jaw room regardless of whether or not the primary gas piping is connected.
The purpose is to make it a safe device with child-proof functions.

Means for Solving the Problems In order to achieve the above object, the range of the present invention includes a main body, a primary gas pipe, a gas lead-in pipe for connecting the primary gas pipe, a power supply cable for power supply, and an operation unit. , comprising an operation key provided on the operation section, a display tube section, and a gas burner, and by setting a special operation with the operation key, the connection between the gas intake pipe and the primary gas piping is established when a normal operation is performed thereafter. Regardless of the presence or absence of this, the gas burner etc. will not burn and other functions including the display tube will operate normally.

Function: By setting a special operation using the operation key, the range of the present invention can be operated normally without causing the gas burner etc. to burn, regardless of whether or not the gas intake pipe and the primary gas pipe are connected. Since the display tube part and other functions operate normally, (1) the product description of the equipment to the equipment purchaser can be safely provided even in places where gas intake pipes are not permitted, such as in the jaw room of a large building; I can do it well.

(2) Regardless of whether the primary gas piping is connected to the gas intake pipe in the jaw room or not, the gas burner, etc. will not burn, and the product description of the equipment to the equipment purchaser will be provided safely and adequately using the equipment. can.

(3) For general consumers and families with small children,
It has a child-proof function that prevents combustion even if gas is supplied to the main unit, so if a child plays a trick, they can operate the device without permission, causing food to burn, or the device being turned off. There is no longer a situation where the equipment is operated completely without food to be cooked, thereby compromising the safety of the equipment or impairing the durability of the equipment.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings. As shown in FIG. 1, the operation section 2 on the front surface of the main body 1 includes a display tube section 3 and various operation keys 4.

Inside the lower cover 6 at the lower front of the main body 1, there is a main cock 7 that is connected to the primary gas pipe 6 attached to the main body 1, and a lead-in pipe 8 that is piped from the gas company to each home.
is connected. Inside the main body 1, there are a combustion part 9 such as a gas burner, a lighting rung 10 for the open storage, a turntable for placing objects to be heated, a motor 11, and the like.

FIG. 2 shows a block diagram of an embodiment of the present invention, which is controlled by a microcomputer 12. In FIG.

That is, the microcomputer 12 controls various operation keys 4 of the operation section 2.
When the heating conditions etc. are set, these heating conditions etc. are displayed on the display tube section 3 and the heating signal +13
Controls the output of 11. When the heating signal ItBn is output, various circuits 13 such as the lighting lamp 1o in the oven, the turntable for placing the object to be heated, and the motor 11 are activated.
is turned on, power from the commercial power source 14 is supplied to the burner combustion circuit 16, and thereby the burner etc. are 9 burned. At that time, in order to prevent gas from leaking and resulting in a gas explosion or gas poisoning, if a gas burner, etc. 9 misfires, a "misfire detection circuit" 16 is activated to completely shut off the gas passage and prevent gas leakage. Microcomputer 12" is constantly monitoring.

Next, an example of a special operator will be described. Among the various operation keys 4 on the operation section 2 on the front of the main body 1, the "Start" key 4
Press a four times, then press the "Cancel" key 4b four times. Then, as an example, [PROOFJ] is displayed on the display tube. Then operate normally. For example, press the "oven" key 4C, set the temperature with the "@degree setting" key 4d, set the cooking time with the "time setting" knob 4e,
When the "Start" key 4C is pressed, the device starts operating. At that time, regardless of whether or not the primary gas pipe 6 is connected to the main cock 7 and the service pipe 8 that is piped from the gas company to each home, when special operations are performed, the combustion part of the gas burner etc. The microcomputer that operates other functions, such as the display tube part 3 of the operation part 2, the lighting lamp 1Q in the oven, the turntable and motor 11 for placing the heated object, etc., without operating it. All you have to do is incorporate the software sequence. Then, the dot display on the temperature display section of the display tube section blinks at regular intervals, and when the set temperature is reached, a buzzer sounds, and "preheating" is completed.

Next, when the cooking time is set and the "start" key 4a is pressed, the cooking time starts counting down and after a predetermined time has elapsed, the display shows "○", the buzzer sounds, and the cooking ends.

FIG. 3 shows a flowchart of the program of the microcomputer 12. An example of special operations will be described using a flowchart. For example, the following "program" can be installed in the microcontroller. After step 101 of "power on", "initialize" in step 102, and then "special operator" in step 103.
Do the following. As an example of a "special operator", among the various operation keys 4 of the operation section 2 on the front of the main body 1, the "start" key 4
! Press L four times and press "Cancel" key 4b four times.

Thereafter, in step 104, l'-PROOFJi is displayed on the display tube according to a command from the microcomputer.

Next, when "oven key set" is performed in step 106, "temperature setting key set" is determined in step 106, and "start key set" is determined in step 107.
A determination is made, and "preheating display" is displayed in step 108. Next, in step 109, it is determined that "the burner does not burn", and in step 110, it is determined that "circuits such as illumination lamps and turntables are operating". Next, in step 111, "the dot display on the temperature display section is stepped up while blinking sequentially at a fixed period, for example, every second", and step 1 is performed.
When it is determined in step 12 that the temperature has reached a predetermined temperature, a "buzzer" is sounded in the next step 113. When ``preheating is complete'' is determined in step 114, the door is then closed and the door is closed, and it is determined in step 116 whether or not ``all cooking time settings'' have been made. Next, in step 116, the cooking time is counted down, in step 117 it is determined that the predetermined cooking time has been reached, in step 118 the display becomes "o" J, and in step 119 the buzzer goes off. sounds and the cooking is "finished" in step 120.

If there is no special operator, the process moves from step 3 to step 121 of determining whether to set the oven key. Thereafter, in step 122 it is determined whether there is a "temperature setting key set", and in step 123 it is determined whether there is a "start key set". Next, after "preheating display" is displayed in step 124, it is determined in step 126 whether or not "the burner is burning". If it is "burner combustion" in step 126, then in step 127 "circuits such as lighting lamps and turntables operate", in step 128 "dots are displayed on the degree display", and then in step 129 "sensor combustion" is performed. The seismic intensity inside the refrigerator is detected, and in step 130, the dots are displayed blinking in sequence according to the temperature inside the refrigerator. If it is determined in step 131 that the temperature has reached 1 set temperature, a buzzer sounds in step 132, and
At 33, "preheating is complete". Then, in step 134, 1
After confirming "Set cooking time", select "Set cooking time" in step 135.
The cooking time display will be “countdown” and step 13
When it is confirmed that 1 predetermined time has been reached in step 6, the display changes to step 137 [to II j, and step 1
At step 38, a "buzzer" sounds, and at step 139, normal cooking is "completed".

Next, we will show how to cancel the "special operator".

``The method for canceling special operation Aj ``Special operation B'' is -
As an example, among the various operation keys 4 of the operation section 2 on the front surface of the main body 1, the "cancel" key a b f is pressed four times, and the "start" key 4 & is pressed four times. After that, according to a command from the microcomputer, PROOFJ is displayed on the display tube and PROOFJ disappears, and the subsequent program steps are changed to "Step 2".
