DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided pottery cooker, and more particularly, to a double-sided pottery cooker in which a lower fire burner is a hot plate type and an atmospheric pressure type and has a heating chamber provided with an upper fire burner and a lower fire burner. About.

2. Description of the Related Art As a double-sided cooker, there is an infrared ceramic burner in which both an upper fire burner and a lower fire burner are surface-burned with all primary air. However, the ceramic burner as the lower fire burner has a burning surface covered with a heat-resistant transparent cover made of glass, and the transparent cover transmits infrared rays of the burning surface, so that the surface is hardly heated to a high temperature and dripped from food. Since the burning is carried out with the food lipids that adhere to the surface of the transparent cover of the lower fire burner, smoke is easily generated.

On the other hand, there is also a low smoke type double-sided ware cooker, and a hot plate type burner is used as an under fire burner. FIG. 6 is a diagram for explaining a hot plate burner. Referring to FIG. 6, the hot plate type burner (201) has a hot plate (20) so as to cover the flame holes (203a) (203a) of the burner pipe (203).
5) is provided. And this burner (201)
Then, the hot plate (205) is heated by the flame (207) at the time of combustion to a high temperature state, radiant heat is radiated, and the food is baked. As described above, since the hot plate (205) is heated to a high temperature, the food lipids dripping from the food are repelled on the surface of the hot plate (205) of the lower fire burner so that they are less likely to adhere to the hot plate, thereby reducing smoke.

A low-smoke type double-sided ware cooker using a hot plate type burner as a lower fire burner is a blast in which the primary air is optimally adjusted using a fan to heat the hot plate of the lower fire burner. Some employ a combustion method. In recent years, in the low-smoking type double-sided ware cooker, in order to prevent food lipids flipped off by the hot plate of the lower-temperature burner from being heated, the user of the utensil is required to remove the food lipid from the heating chamber. In order to avoid having to feel the heat of the radiant heat, a heating chamber having a door attached to the front thereof has been widely used.

[0005]

However, a low-smoke type double-sided cooking device employing a blast combustion system in which all primary air is burned in a hot plate type lower burner must incorporate a fan. However, the structure becomes complicated and expensive. On the other hand, if we consider a low-smoke double-sided cooker that uses a hot plate type lower fire burner and an atmospheric pressure type (Bunsen combustion method) that burns with primary air and secondary air, Heat is easily trapped near the exhaust passage side, and the type in which the front side of the heating chamber is closed by closing the door has a problem that the lower side of the heating chamber is almost closed, so the supply and exhaust of the lower fire burner is not possible. It is thought to be sufficient. Therefore, it is considered that the temperature of the hot plate of the lower fire burner does not rise to a temperature sufficient to reduce smoke.

Therefore, the present invention relates to a double-sided porcelain cooker in which the lower fire burner is a hot plate type burner of an atmospheric pressure type and the smoke can be reduced as much as possible even if a door is attached to the front of the heating chamber.

FIG. 1 is a front view of a double-sided pottery cooker according to an embodiment of the present invention, and FIG. 2 is a view of the double-sided pottery cooker of FIG. 1 as viewed from the back. Yes, FIG.
FIG. 4 is a sectional view taken along line III-III of FIG. 1, and FIG. 4 is a perspective view of a double-sided porcelain cooker viewed from above for explaining the exhaust gas rectifier plate of FIG. 1.

The double-sided cooker (101) has a heating chamber (103) in a main body (102). Inside the heating chamber (103), an upper fire burner (105) and a lower fire burner (10
7) is provided. The upper fire burner (105) is
(103) and is located on the upper side of the
a) and an upper fire rear burner (105b) on the rear side. Both the upper fire front burner (105a) and the upper fire rear burner (105b) are ceramic burners whose surfaces are burned with all primary air, and the heat radiation direction is downward. Here, the ceramic burner was used as the upper fire burner (105) (the upper fire burner (105a) and the upper fire burner (105b)) because the food lipids from the food to be fired dropped down and adhered. This is because it is not necessary to consider the fact that the food material is baked so as to look delicious by taking advantage of the fact that the heat can be uniformly distributed. In addition, the upper fire front burner (105a) burns when the operation knob (106a) for the upper fire front burner of the operation unit (104) is operated, and the upper fire rear burner (105b) operates behind the upper fire of the operation unit (104). The burner operation knob (106b) is operated to burn.

The lower fire burner (107) is a burner that burns with primary air and secondary air from an air supply opening, which will be described later, and is located below the heating chamber (103). Burner
(107a) and a rear-side lower fire rear burner (107b). The lower fire front burner (107a) and the lower fire rear burner (107b) both extend at predetermined intervals in the front-rear direction between the side surfaces of the main body (102), and the heat radiation direction is upward. The lower fire front burner (107a) and the lower fire rear burner (107b) are burned by operating the lower fire burner operation knob (108) of the operation unit (104).

A door (109) is attached to the front of the heating chamber (103). The door (109) can be opened and closed, and food can be put into the heating chamber (103) by opening it, and by closing it, food lipids generated from food during baking do not splash outside the heating chamber (103). The user of the appliance also
It is devised so as not to feel the heat of the radiant heat from (103).

The upper fire front burner (105a) and the upper fire rear burner (1
05b) is provided with an exhaust opening (110),
The exhaust gas generated in the heating chamber (103), that is, the exhaust gas generated by the combustion of the upper fire burner (105) and the exhaust gas generated by the combustion of the lower fire burner (107) passes through an exhaust passage (110) connected to the opening (110). 111)
Exhausted upward through. However, the opening (110) is set to have a small opening area by providing the exhaust gas rectifying plate (113), so that the flow rate of the exhaust gas is increased and the exhaust is smoothly performed.

The door (109) is not completely closed even when it is closed, and is opened in a half-open state in which the exhaust can be performed smoothly and there is a gap at an appropriate angle such that the cooking state can be visually recognized. State. This is because the supply / exhaust air is blocked only by exhausting from the exhaust opening (110), and the lower fire burner (107) causes poor combustion.Therefore, exhaust gas is also exhausted from the gap. is there. Further, the half-opening has an advantage that the user can see the cooking state by looking at the heating chamber (103) during cooking.

Further, the exhaust gas flow regulating plate (113) is provided on the operation section (104) side, and the position of the opening (110) is on the side away from the operation section (104) side. The operation unit (104) side is a lower fire burner (107)
Is the primary air supply side for the
3) If there is no air supply, the secondary air will be partially over-supplied, which may lead to combustion failure.Therefore, the secondary air should be supplied sufficiently from the air supply opening described later to achieve appropriate and uniform combustion as a whole. In order to perform the operation, the exhaust speed on the operation unit (104) side is suppressed by the exhaust current regulating plate (113).
Furthermore, an exhaust flow straightening plate (113) provided on the operation unit (104) side.
As a result, the amount of exhaust gas flowing on the operation unit (104) side is reduced, and an overheating state of the operation unit (104) is prevented.

As described above, the provision of the exhaust gas flow regulating plate (113) and the smooth exhaust can be achieved by providing the upper fire burner (105) and the lower fire burner (107) in the heating chamber (103). A door (109) is attached to the front of the heating chamber (103), and the double-sided porcelain cooker (10
It is important when reducing smoke in 1). This is because the heat generated by the combustion of the upper fire burner (105) is trapped above the heating chamber (103), and the exhaust gas generated by the combustion of the lower fire burner (107) is less likely to be exhausted. This is because the supply of combustion air to the burner (107) becomes insufficient, so that the temperature of the hot plate of the lower fire burner (107) cannot be increased, thereby reducing smoke reduction.

On the other hand, below the heating chamber (103), there is provided a water tray (115) which can be pulled out forward. As shown in FIG. 5, the water tray (115) is composed of a main body (117) and a handle (119) provided forward from the upper end of the front surface of the main body (117). A flat portion (119a) that extends forward from the upper end of the front surface of the main body (117) and serves as the lower surface of the heating chamber (103) together with the water level of the water contained in the main body (117), and a front end of the flat portion (119a). Hanging portion extending downward (119b)
It is composed of That is, the depth of the main body (117) is L1, and the length from the rear surface of the main body (117) to the position of the hanging portion (119b) of the handle (119) is equal to the depth of the heating chamber (103). The corresponding L2, a plane portion of width (L2-L1)
(119a) constitutes a part of the lower surface of the heating chamber (103).

A plurality of front air supply openings (121) for secondary air are formed in the plane portion (119a) in the longitudinal direction. The opening direction of the front air supply opening (121) is
The exhaust gas generated in (7) is discharged into the exhaust passage (11
Since the vertical direction is the same as the direction flowing toward 1), the air supply and exhaust are designed to be smooth. Therefore, the secondary air flows from the front air supply opening (121) to the heating chamber (1).
03) Air is supplied smoothly downward, and sufficient combustion air is supplied to the lower fire burner (107) provided below the heating chamber (103), and the temperature of the hot plate of the lower fire burner (107) is increased. It is planned. Moreover, the handle (11) in which the front air supply opening (121) is formed
In the case of 9), the hand may be touched at the time of drawer, but the handle (119) is cooled by the flow of the secondary air, and the temperature is lowered. Therefore, the lower fire burner
While the temperature of the hot plate of (107) is raised, the temperature of the handle (119) is prevented. In addition, the flat portion (119a) extends in the horizontal direction and does not form a gap for the air supply opening that can be seen from the front of the instrument body (102), so that dust and the like can be kept inside the heating chamber (103). It is devised so as not to enter easily, and a dustproof effect is obtained.

A plurality of front air supply openings (121) are formed in the longitudinal direction, and a lower fire burner (107) is provided from below the heating chamber (103).
The secondary air can be evenly supplied to the
In consideration of 3) and the later-described rear air supply opening, temperature unevenness in the longitudinal direction of the hot plate is prevented. However,
Since air supply is performed, a plurality of openings are not necessary, and one opening may be used. The size of one opening is not limited, and the opening type may be a punch hole, a louver, or the like.

Also, the front air supply opening need not necessarily be formed in the water tray (115). A front air supply opening (121) is formed on the front side of the appliance body (102), while a pair of rear air supply openings (123a) and (1
23b) is formed, and the combustion air is sufficiently supplied to the lower fire burner (107) to raise the temperature of the hot plate.
In addition, air supply from the rear side is limited to both ends with respect to the lower fire burner (107).
(103) will give a draft effect to the exhaust gas inside,
The exhaust gas from the lower fire burner (107) is smoothly exhausted. As described above, it is important to smoothly exhaust the lower fire burner (107). By smoothly exhausting the exhaust gas, the front air supply opening (121), the rear air supply opening (123a), and ( The supply of the secondary air from 123b) to the lower fire burner (107) also becomes smooth, and the temperature of the hot plate of the lower fire burner (107) is increased.

Since the air supply opening at the rear side of the instrument body (102) is only at the lower ends, it is smaller than the case where it is extended in the longitudinal direction, and as a result dustproofing is achieved. Further, the rear air supply opening is limited to the lower end sides for the formation position, but may be a state where a plurality of small openings are gathered at that position, and the opening type is the same as the front side, such as a punch hole, A louver or the like may be used.

[Others] The upper fire burner is not limited to the ceramic type, but may be another type such as a hot plate type. Although the front air supply opening as the air supply opening at the lower part of the instrument main body is provided, it is not always necessary to provide the front air supply opening.

The temperature of the hot plate of the lower fire plate type burner rises to about 700 ° C. by the front air supply opening, the pair of rear air supply openings, and the exhaust gas flow control plate, and the food lipid dripped from the food to be baked is heated. The effect of reducing smoke was obtained without flicking off and adhering on the surface of the plate, but it was not necessary to provide all the components.

In the embodiment, the door is half-opened even in the closed state. However, if the burner burns well and the temperature of the hot plate is high, the door may be completely closed in the closed state. Good. In this case, the user can visually recognize the cooking state during cooking, for example, by attaching a transparent glass window to the door.
