Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the structure of a burner for a gas stove having two large and small burners.

Conventional technology Conventional gas stoves with two large and small burners are completely independent from ignition to flame detection and flame power adjustment.
Ignition, flame detection, and fire power adjustment are sometimes performed by a single control device, but as shown in Figure 3, the large burner cap 1
and the small burner cap 5 are all constructed completely independently.

Conventionally, there was no need to integrate the large burner cap 1 and the small burner cap 5, and with the conventional configuration of the large burner head 2 and the small burner head 6, the large burner cap 1 and the small burner cap 5 were This is because it is thought that if they are integrated, there is a risk that problems will occur in the performance of either one.

Moreover, the shape of the upper surface of the large burner cap 1 forms a downward slope toward the central opening in order to take in secondary air.

Problems to be Solved by the Invention However, in recent years, gas stoves built into system kitchens have become popular, and there are problems with ease of operation, ease of maintenance, structure that prevents boiled liquid from entering the appliance, and installation by contractors. With the increasing demand for ease of handling, etc., the conventional configuration in which the two large and small burner caps are independent has a major drawback in that the small burner cap is easily lost, and when combustion is controlled by one control device, It is necessary to have a structure in which the relative position of the large burner cap and the small burner cap is maintained constant, which also has the drawback of high cost. Furthermore, the top surface of the large burner cap is sloped downward toward the central opening, making it easy for boiled liquid and the like to enter the inside.

Means for Solving the Problems The gas stove of the present invention which solves the above-mentioned problems comprises a large burner character and a small burner cap integrated together, and further includes a lid that covers the opening in the center of the large burner cap.
This is also integrated, and the upper surface of the large burner cap and the upper surface of the lid are sloped downward toward the outer periphery.

Function The gas stove of the present invention prevents loss during installation or maintenance by integrating the small burner cap with the large burner cap as described above. By making the slope downward, the boiled liquid flows down to the outer periphery.

Example An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, a first flame hole group 3 formed by a large burner head 2 is provided on the outer periphery of the large burner cap 1, and an opening 4 is provided in the center for secondary air intake. has. A small burner cap 6 and a small burner head 6 are exposed in this opening 4, and the upper surface of the burner cap 5 is integrally formed with a lid 7 that covers the central opening 4 of the large burner cap, and the upper surface of the large burner cap 1 The top surface of the lid 7 slopes downward toward the outer periphery.

The large burner cap 1 and the small burner cap 5 are integrally formed by connecting portions 8 at two opposing locations. Next, on the outer periphery of the small burner cap 5, a main flame hole group 9 consisting of a plurality of round holes is formed as a second flame hole group, and the lower surface of the small burner cap 5 and the small burner head e. The fitting portion of the small burner cap 5 and the small burner head 6 constituting the auxiliary flame hole group 1o is cylindrical and has a constant interval.

ζThe height of the auxiliary flame hole group 10 was determined experimentally so that the size of the opening 4 and the amount of secondary air would be necessary and sufficient at a position higher than the upper end of the opening 4 in the center of the large burner cap. It is something that can be done. A slit flame hole 11 is provided on the upper surface of the large burner cap 1 to transfer the flame from the second flame hole group to the first flame hole group. It should be placed in the middle so as not to interfere with the flame coming from. Although the configuration is such that the spark plug 12 is arranged near the second group of flame holes formed in the small burner cap 5 to ignite, considering the case where the flame does not transfer to the opposite side through the above-mentioned connecting portion 8, A thermocouple 13 serving as flame detection means is arranged on the opposite side of the spark plug to ensure safety, and the slit flame hole 11 is also arranged on the same side for the same reason.

Furthermore, the large burner head 2 and the small burner head 6 are configured to maintain a constant relative position via the burner mounting plate 14.

In this way, the large burner head 2 and the small burner head 6 are configured to minimize variations in their relative positions, and the gap between the fitting portions of the small burner cap 6 and the small burner head 6 is kept constant to absorb some variation. This structure makes it possible to integrate the large burner cap and the small burner cap, which has been difficult in the past. The auxiliary flame hole group formed on the small burner cap further has the effect of stabilizing performance, such as preventing lift of the flame of the flame hole group formed on the small burner cap.

Effects of the Invention As described above, the gas stove of the present invention has the following effects.

(1) By integrating the large burner cap and the small burner cap, it is possible to reduce the cost and prevent the loss of the small burner cap during maintenance, installation, etc.

@) By integrally constructing the lid that covers the central opening of the large burner cap and sloping the top surface downward toward the outer periphery, it is possible to prevent boiled liquid from entering the inside.

(3) By configuring the small burner cap's flame hole group with a main flame hole group made of round holes and an auxiliary flame hole group below it, the flame is stabilized and variations in the position of large and small burner heads are absorbed. can do.

(4) The large and small burner caps can be integrated, and the slit flame hole for flame transfer and the main flame hole of the small burner cap can be set in a specific positional relationship, and mutual flame interference can be prevented.
