  6. The aforementioned through hole includes a first through hole and a second through hole. The heat source is positioned between the first through hole and the second through hole. The first rib is positioned on the heat source side of each of the first and second through holes. The heating appliance according to claim 1 or 2, wherein the second rib is arranged on the opposite side of the heat source from each of the first and second through holes.
  7. A heating plate positioned above the heat source and having through holes running vertically through it, A first rib extending downward from the burning plate on the heat source side of the through hole, A grill plate comprising a second rib that extends downward from the grilling plate on the opposite side of the through hole from the heat source and is longer than the first rib.

Description

This technology relates to a heating appliance and grill plate for cooking food. A barbecue grill has been proposed in which a gas burner is positioned beneath a griddle plate with multiple slits arranged side by side. The slits extend in a first direction. The multiple slits are aligned in a second direction perpendicular to the first direction at the center of the griddle plate. Two ribs protrude from the underside of the griddle plate, extending in the second direction. One rib is close to one end of each of the multiple slits, and the other rib is close to the other end of each of the multiple slits. A water tank is positioned beneath the slits. In the first direction, the gas burner is positioned away from the slits. During cooking, liquids released from food, such as meat fat, enter the slits and drip down the ribs into the water tank. If a portion of the gas burner flame is directed towards the center along the underside of the griddle, the ribs deflect it downwards, preventing the flame from heading towards the slits.

The present invention will be described below based on drawings showing a heating appliance according to an embodiment. In the following description, the directions shown in the figures (up, down, front, back, left, and right) will be used as appropriate. These directions are for ease of understanding and are not limited to them. Figure 1 is a schematic perspective view of the heating appliance 1, Figure 2 is a schematic front view of the heating appliance 1, and Figure 3 is a schematic left side view of the heating appliance 1. The heating appliance 1 comprises a housing 2 and a grill plate 7. The housing 2 is a rectangular parallelepiped extending to the left and right. The entire top surface of the housing 2 is open. The grill plate 7 is rectangular in plan view and includes a grilling plate 70 extending to the left and right. The grilling plate 70 is provided in the opening on the top surface of the housing 2. The grilling plate 70 is shallow and tray-shaped. The central portion of the grilling plate 70 in the front-to-back direction is thicker than the other portions of the grilling plate 70, forming a raised portion 70a that protrudes upward. The raised portion 70a extends over almost the entire width of the grilling plate 70. The upper surface of the raised portion 70a is a curved surface that protrudes upward. Multiple first through-holes 70b are formed in the recessed portion of the burnt plate 70, in front of the raised portion 70a, extending vertically. These multiple first through-holes 70b are aligned horizontally. Similarly, multiple second through-holes 70c are formed in the recessed portion of the burnt plate 70, in rear of the raised portion 70a, extending vertically. These multiple second through-holes 70c are aligned horizontally. Each first through-hole 70b and each second through-hole 70c forms a slit-like structure extending front to back. As mentioned above, since the upper surface of the raised portion 70a has a curved shape that protrudes upward, liquid adhering to the upper surface of the raised portion 70a easily moves to the first through hole 70b or the second through hole 70c, and liquid, such as oil, is less likely to accumulate in the raised portion 70a. A connector 4 for a power cable (not shown) is provided on the lower right side of the housing 2. The power cable connects the AC power supply 40 (Figure 11) to the cooking appliance 1. A dial-type control unit 3 is provided on the front of the housing 2. The user operates the control unit 3 to turn the cooking appliance 1 on or off and to set the heat level for heating. For example, the control unit 3 is configured to allow selection of one of the following: "High Heat," "Reduced Smoke," "Low Heat," or "Off." As shown in Figure 3, an insertion/removal opening 1a for inserting and removing the water tray 5 is formed on the left side of the housing 2. The insertion/re
