[Operation and effect of cover member]

Hereinafter, operations and effects of the cooking appliance according to an embodiment of the present invention will be described.

2 to 4, water supplied from the water supply device 35 flows into the water storage tank 32 through the connection pipe 37, and the water flowing into the water storage tank 32 flows into the steam heater 33. ) to generate steam, and the generated steam is introduced into the cooking chamber 15 and circulated inside the cooking chamber 15, so that cooking using the steam is performed.

At this time, steam is sprayed downward into the cooking chamber 15 through the steam spraying member 39 . During the process of spraying steam through the steam spraying member 39, some of the steam may be condensed in the form of water droplets condensed on the inner and outer walls of the steam spraying member 39 and around the spray hole 39a.

In particular, there is a high possibility that this phenomenon occurs when an excessive amount of steam is injected, at the beginning of steam injection when the temperature of the steam injection member 39 is still low, or after steam injection is completed. In addition, this phenomenon may occur even when heating of food with a lot of moisture is performed in the cooking chamber 15 even though steam is not sprayed.

Water droplets condensed on the steam spraying member 39 are collected around the spraying hole 39a and fall downward when the weight is sufficiently increased. These water droplets fall toward the first cover part 110 disposed under the spray hole 39a. In addition, the water droplets that have fallen in this way accumulate in the concave portion 115 formed in the first cover portion 110 and do not fall toward the cooking object or the bottom surface of the cooking chamber 15 .

That is, the cover member 100 provided so that the first cover part 110 is disposed under the spray hole 39a effectively prevents water droplets formed on the steam spraying member 39 from falling on the cooking water or the bottom surface of the cooking chamber 15. can block

As the cover member 100 is installed as described above, the steam discharged through the spray hole 39a is not sprayed downward, but through the lateral passage formed between the spray hole 39a and the cover member 100 in a lateral direction. supplied to the inside of the cooking chamber 15.

That is, the steam is supplied to the inside of the cooking chamber 15 in a form of spreading to both sides of the cover member 100 without being directly sprayed downward. Accordingly, the steam is supplied in a form in which steam is evenly spread throughout the cooking chamber 15 without being intensively sprayed on only a portion of the cooking chamber 15 . Accordingly, since steam can be supplied evenly and efficiently throughout the entire cooking chamber 15, the efficiency of steam cooking and the result of steam cooking can be improved.

The cover member 100 has a lateral length, that is, a narrow width, compared to a longitudinal length. Preferably, the width of the cover member 100 may be set to have the narrowest width within a range in which the first cover part 110 may include the concave portion 115 therein.

When the cooking chamber 15 is opened, the cover member 100 is configured to be exposed to the outside of the cooking chamber 15 . Since it is difficult to say that it is aesthetically pleasing for the cover member 100 to be exposed to the outside of the cooking chamber 15, the cover member 100 is formed as narrow as possible to minimize external exposure. Even in this case, it goes without saying that the width of the cover member 100 should be set to a width sufficient for the first cover part 110 to contain the concave portion 115 therein.

A second cover part 120 is provided in front of the injection hole 39a, and a second cover part 120 is provided behind the injection hole 39a. The second cover unit 120 and the third cover unit 130 are components required to fix the first cover unit 110 to the lower portion of the nozzle 39a, but are not provided only for this purpose.

The second cover part 120 provided in front of the spray hole 39a forms a blocking wall disposed between the spray hole 39a and the door 16 (see FIG. 1). Due to the second cover part 120, direct spraying of steam from the injection port 39a to the front side, that is, to the door 16 side, is partially suppressed.

Even if it is unavoidable that steam is formed on the door 16 when the cooking chamber 15 is filled with steam, steam is sprayed directly toward the door 16 from the beginning of steam spraying on the door 16. This frosting can be suppressed by the second cover part 120 .

The third cover part 130 provided behind the spray hole 39a forms a blocking wall disposed between the spray hole 39a and the steam outlet 40 . The passage between the injection port 39a and the steam outlet 40 is partially blocked by the third cover part 130 .

If the steam injected into the cooking chamber 15 is immediately discharged through the steam outlet 40 before being applied to food, steam is wasted and it is difficult to sufficiently supply the steam in the cooking chamber 15 as expected.

In this embodiment, since the passage between the nozzle 39a and the steam outlet 40 is partially blocked by the third cover 130, the steam injected through the nozzle 39a directly hits the steam outlet 40. It is possible to block a large part of the discharge through. Accordingly, the cooking appliance of the present embodiment may be provided in a form with improved functions so that steam can be supplied quickly and sufficiently while preventing waste of steam.

The upper heater 19 includes a plurality of heat transfer pipes 19a disposed at a predetermined interval in the lateral direction. Also, the plurality of heat transfer pipes 19a are connected to each other at the front or rear of the upper heater 19 to form one upper heater 19 .

The upper heater 19 is disposed to occupy most of the upper surface of the cavity 11 inside the cooking chamber 15 . Accordingly, the steam spraying member 39 is disposed between the heat transfer tubes 19a spaced apart from each other in the lateral direction when viewed from the bottom and the gap between the heat transfer tubes 19a. Also, the cover member 100 is disposed in the gap between the pair of heat transfer tubes 19a adjacent to each other in the lateral direction.

The cover member 100, in order to be disposed in such a narrow gap, is provided in a form narrower than its longitudinal length. Specifically, the lateral length of the cover member 100, that is, the width of the cover member 100 is set shorter than the distance between the pair of heat transfer tubes 19a disposed on both sides of the cover member 100 in the lateral direction.

Since the cover member 100 is provided with such a narrow width, the cover member 100 is not exposed to the outside when the cooking chamber 15 is opened, and the case where the upper heater 19 is installed above the cooking chamber 15 Even the cover member 100 can be easily installed without interference with the upper heater 19 can be provided together.
