Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heating cooker that heats an object to be cooked with at least a heat source of steam.

[0002]

[Prior Art]

 As one for supplying steam into the cooking chamber and heating the food to be cooked by using the thermal energy of the steam, there is, for example, one disclosed in Japanese Utility Model Publication No. 61-172905, in which case, Since the door is so-called vertically opened, water drops attached to the inner surface of the door rarely fall onto the floor after the door is opened when cooking is completed, but it is used for commercial purposes such as restaurants. In the relatively large cooker, there is a problem that it is difficult to put in and out the food to be cooked unless the door is opened sideways.

Therefore, when the door is configured to open sideways, for example, as shown in FIG. 4, a water receiver (101) for receiving water droplets attached to the inner surface of the door (100) is attached to the lower part of the door, and when the door is closed, water When the inner surface (102) of the receiver (101) is configured to be in contact with the peripheral wall (104) of the opening (103), water droplets will pass through the peripheral wall from between the inner surface (102) and the peripheral wall (104). It easily falls, and it is necessary to further provide another water receiving member or the like below the water receiving (101), which causes a problem of cost increase due to an increase in the number of parts.

[0004]

[Problems to be solved by the device]

 The present invention aims to prevent water droplets adhering to the inner surface of the door from falling onto the floor surface or the like during cooking, in the case where steam is supplied into the cooking chamber by forming the cooking chamber into a substantially hermetically sealed state.

[0005]

[Means for Solving the Problems]

 According to the present invention, in a case where a substantially sealed cooking chamber having an opening for opening and closing by a door is defined and formed in an outer case, and a discharge port for supplying steam is provided at an appropriate position in the cooking chamber. , Located below the lower edge of the door around the opening and protruding from the lower end of the door with the tip facing downward, and at the bottom of the door, below the draining projection when closed. It is equipped with a water pan.

[0006]

[Action]

 During heating, steam is supplied from the discharge port into the cooking chamber, and the food to be cooked in the cooking chamber is heated by the steam. Water droplets that adhere to the space drop down, but they are guided through the water drain protruding below the opening into the water pan to prevent them from falling to the floor.

【Example】

 First, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. (1) is a cooker main body mainly used for business such as restaurant, which has an opening (2) on the front surface and a door (3) on the opening. ), A substantially closed cooking chamber (4) that can be opened and closed, a circulation fan (5) consisting of a sirocco fan mounted in the approximate center of the back of this cooking chamber, and a partition formed below this fan. The combustion chamber (6) and one end (7) (7) ··· are connected to the upper wall (8) of this combustion chamber, and the other end (9) (9) · · is the upper part of the cooking chamber (4). Mainly composed of a plurality of substantially L-shaped heating pipes (11), (11), ... Connected to the exhaust pipe (10) on the front side, the exhaust pipe (10) includes heating pipes (11) (11) ) ······················· Installed in the front-back direction of the top surface of the cooking chamber (4), connecting the heating pipes (11), (11) ··· to one end, and the outer case (12) at the rear end. ) Is equipped with a discharge hole (13) opened at the upper back.

On the other hand, in the combustion chamber (6), a gas burner (15) is housed and installed with the flame hole (14) facing forward in the rear of the inside thereof, and the combustion chamber (6) is located rearward of the cooking chamber (4). An air supply fan (17) for supplying combustion air to the gas burner (15) is connected to the rear upper surface wall (16).

(18) is a solenoid valve set mounted on the rear upper surface wall (16) of the combustion chamber (4), and controls the fuel supply to the gas burner (15).

Reference numeral (19) is a steam supply pipe that opens through the discharge port (20) into the cooking chamber (4) by penetrating the rear wall (21) of the cooking chamber (4) at an appropriate position, and the combustion chamber (6). Located above the rear upper wall (16) is a steam shutoff valve (22) for controlling the supply of steam.

(23) is a bottom plate that constitutes the bottom surface of the cooking chamber (4), and is configured as a relatively shallow survivor shape, and a drain port (24) is formed at the bottom thereof, and a drain pipe is provided at this drain port. (25) is linked.

Further, the door (3) has an inner surface (26) mounted with a door packing (28) as shown in FIG. 3 at a position facing the peripheral wall (27) in front of the opening (2). In addition, a water receiver (30) having a receiving opening (29) extending inward from the inner surface (26) of the door is detachably attached to the lower part.

On the other hand, below the opening (2) of the peripheral wall (27), there is a recessed fitting portion (31) which is located opposite to the water receiver (30) and accommodates the inner portion of the water receiver. While being formed, it is located at the upper end of this concave fitting portion, and the tip is inclined between the lower end of the door (3) and the water receiver (30) toward the center of the receiving port (29). A protruding draining protrusion (32) is integrally formed.

For cooking, after the object to be cooked is stored in the cooking chamber (4), the cooking temperature, the cooking time, etc. are input from the operation unit (not shown), and the cooking start operation is performed to circulate the food. When operating the fan (5) and the air supply fan (17) and burning the gas burner (15) and performing steam heating, open the steam shutoff valve (22) and open the discharge port (20). By supplying steam into the cooking chamber (4), the combustion hot air is supplied to the heating pipes (11) (11) ··· by the combustion of the gas burner (15) to heat it and the surface of the heating pipe. At the same time that the food to be cooked is heated by the radiant heat from the heating fan (5), the surface of the heating pipes (11) (11) Heat almost uniformly.

On the other hand, the combustion hot air that has passed through the heating pipes (11), (11), ... Further passes through the inside of the exhaust pipe (10) to heat the exhaust pipe with residual heat and then discharge holes (13). It is further discharged to the outside, and at this time, the food to be cooked is also heated in the exhaust stack (10).

During the cooking, steam supplied from the discharge port (20) is condensed and drops on the bottom plate (23), and then discharged from the drain port (24) to the outside through the drain pipe (25). On the other hand, the water droplets that have condensed on the inner surface (26) of the door (3) fall down along this inner surface, part of which is discharged to the outside from the bottom plate (23), and part of which falls on the peripheral wall (27) and the inner surface (26). ) And collect.

Therefore, if the door (3) is opened after cooking, etc., water droplets adhering to the inner surface (26) of the door will drop, but these water droplets will be released on the draining protrusion (32) when the door (3) is opened. After it falls, it will fall into the water catchment (30) along this drainage protrusion and prevent it from falling to the floor surface.

When water drops collect in the water receiver (30), the water receiver (30) may be appropriately removed from the door (3) and the water may be discarded.

[0019]

[Effect of the device]

 With the configuration according to the present invention, it is possible to reliably prevent water droplets adhering to the inner surface of the door during cooking from falling due to the opening operation of the door while cooking, to the floor surface, etc. The purpose of this is to prevent accidents such as slippage of the human body due to water drops falling on the floor.
