The following are a kind of embodiments of cooking apparatus provided by the utility model.

Embodiment one

It is a kind of diagram of cooking apparatus embodiment one of the utility model referring to Figure 1 to Fig. 4.

A kind of cooking apparatus, including pot body 10 and pot cover 20, pot cover 20 are covered on the open-mouth of pot body 10, set on pot cover 20 The outlet passageway 2 for being passed through the inlet channel 1 of steam in oriented pot body 10 and steam in pot body 10 being discharged, the pot body 10 include Interior pot 3 and heat preservation outer pot 4, have a gap 101 between the interior pot 3 and outer pot 4, the inner space 31 of the interior pot 3 and should between Gap 101 be connected to, inlet channel 1 inwardly pot 3 inner space 31 setting and be passed through steam.

Interior pot 3 is for loading food.Referring to shown in Fig. 3, the present embodiment is equipped with inlet channel 1 on pot cover 20 and outlet is logical The importing and export of steam in pot body 10 are realized in road 2.Wherein inlet channel 1 inwardly pot 3 inner space 31 setting and be passed through steaming Vapour makes steam first direct contacting foodstuff, to reach optimal heating effect.

In addition, having gap 101 between interior pot 3 and outer pot 4, the inner space 31 of interior pot 3 is connected to the gap 101, makes The steam that must be passed through in interior pot 3 can overflow interior pot 3 and be passed into the gap 101, and steam is also filled in gap 101, make interior 3 side walls of pot are also heated, to improve heating effect.Furthermore the outer pot 4 with thermal insulation property can prevent heat from distributing outward, Improve the utilization rate of steam heat, at the same also assure interior 3 side of pot to temperature be not lost, improve culinary art effect.

The width size in the gap 101 is that 2-50mm is the most suitable, and heating effect is preferable under the size.When 101 mistake of gap Hour, the water droplet condensed on pot cover 20 can be overfilled by the gap 101, and substantially reduces the quantity of steam in gap 101, then Influence heating effect.And when gap 101 is excessive, the volume of entire cooking apparatus is big, and space utilization rate is low, and is greater than 50mm When, the thickness of steam is enough, and quantity of steam needed for lateral heating effect tends to be saturated, and continues growing what steam promoted heating effect It influences small.

Preferably, pot cover 20 is covered on the outer pot 4, is formed between interior pot 3 and pot cover 20 and be connected to the inner space 31 With the communicating passage 102 in the gap 101.The present embodiment makes pot cover 20 and interior by the way that directly pot cover 20 is covered on outer pot 4 The communicating passage 102 for being connected to the inner space 31 and the gap 101 is directly formed between pot 3, structure is simple, is easy to real Existing, user uses and also facilitates when cleaning.

The structure that the present embodiment pot cover 20 is covered on the outer pot 4 has following several situations: one, it is vertical to be located at interior pot 3 Pot cover 20 on direction is partially in the top of interior pot 3, to make to form the communicating passage 102 between pot cover 20 and interior pot 3； Two, the medium position of pot cover 20 is recessed downwards enters in interior pot 3, and 32 position of pot edge that pot cover 20 is located at interior pot 3 is then concave up And if be in pot edge 32 top, to make to form the communicating passage 102 between pot cover 20 and interior pot 3.Wherein, pot cover 20 The lid coincidence of cover rim and outer pot 4 sets the pot edge 32 that can be lower than interior pot 3, can also be higher than the pot edge 32 of interior pot 3.
