Wherein, the body includes the culinary art chamber, and material holds the piece detachably and places in the culinary art chamber. In addition, the heat dissipation component is arranged on the body and can dissipate heat for the electric elements of the cooking appliance and the interior of the cooking appliance. The heat dissipation assembly comprises a heat dissipation fan and a heat dissipation air duct; the heat dissipation fan can drive the airflow in the heat dissipation air duct to flow, so that the purpose of heat dissipation is achieved. In addition, the material holds the piece and includes holding body and heat exchange tube, holds the food that can place waiting to cook.

Particularly, after the material holds the piece and places the culinary art chamber, the heat exchange tube that the material held the piece can be linked together with the first air outlet in heat dissipation wind channel, and then makes the cooling fan can be through the heat dissipation wind channel to the interior air supply of heat exchange tube to hold the piece cooling through the air-cooled mode for the material, reduce the risk that the material that the culinary art was accomplished the back high temperature holds the piece and scalds the user.

Specifically, in the daily use process, after a user places cooked food into the material containing piece, placing the food to be cooked and the material containing piece into the cooking cavity together; at this time, the heat exchange tube of the material containing piece can be communicated with the first air outlet of the heat dissipation air duct. Then, the cooking appliance cooks the food on the material containing member.

After cooking, the temperature of the material containing piece is also higher, and the user has the risk of being scalded if the user directly takes the material containing piece. At this moment, the cooling fan can operate, and the cooling fan is through the first air outlet in cooling wind channel to the heat exchange tube in supply air, can carry out heat transfer with holding the body when the air current is through the heat exchange tube, reduces the temperature that holds the body fast.

Therefore, on one hand, the temperature of the containing body can be reduced through air flow, the risk of scalding a user by the material containing piece is reduced, and on the other hand, the user can take out the material containing piece in a short time under the condition that the user does not wear gloves, so that the meal taking time of the user can be greatly shortened. Meanwhile, the temperature of the containing body can be quickly reduced through the air flow in the heat exchange tube, so that the tabletop or the counter cannot be scalded when the containing body is placed on the tabletop or the counter.

In addition, because the heat exchange tube is arranged on the containing body, namely, the object to be cooled is the containing body instead of the cooking cavity of the cooking appliance, and the cooling medium is air flow, the temperature in the cooking cavity is less influenced by the medium in the heat exchange tube, thus the controllability of the temperature of food can be ensured, and the accurate positioning is achieved, only the containing body is cooled, and the food cannot be cooled.

In some possible designs, a gap is provided between the inlet of the communication pipe and the first air outlet, and the baffle plate can extend into the gap to close the first air outlet.

In this design, the inlet of communicating pipe sets up towards first air outlet to guarantee to have the clearance between the inlet of communicating pipe and the first air outlet, the size of this clearance matches with the thickness of baffle. Therefore, under the condition that the door body is in a closed state, the baffle plate can extend into a gap between the inlet of the communicating pipe and the first air outlet and block the first air outlet. At this time, the first air outlet is in a closed state, and the air flow generated by the heat radiation fan is used for radiating the electric elements in the cooking utensil, so that the heat radiation efficiency of the electric elements is improved.

Detailed Description

In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

A cooking appliance 100 provided according to some embodiments of the present invention is described below with reference to fig. 1 to 14. Wherein the dashed arrows in fig. 7, 8 and 9 indicate the direction of airflow.

As shown in fig. 1, 2 and 3, a first embodiment of the present invention proposes a cooking appliance 100 comprising: the body 102, the heat dissipating assembly 106, and the material holder 112.

Wherein the body 102 includes a cooking cavity 104, and the material holder 112 is detachably disposed in the cooking cavity 104. In addition, the heat dissipation assembly 106 is disposed on the body 102 and is capable of dissipating heat for the electrical components of the cooking appliance 100 and the inside of the cooking appliance 100. As shown in fig. 7, 8 and 9, the heat dissipation assembly 106 includes a heat dissipation fan 108 and a heat dissipation air duct 110, and the heat dissipation fan 108 can drive the air flow in the heat dissipation air duct 110 to flow, so as to achieve the purpose of heat dissipation. As shown in fig. 4 and 5, the material accommodating part 112 includes an accommodating body 114 and a heat exchanging pipe 116, and the accommodating body 114 can accommodate food to be cooked.

Specifically, as shown in fig. 6, after the material containing member 112 is placed in the cooking cavity 104, the heat exchange tube 116 of the material containing member 112 can be communicated with the first air outlet 158 of the heat dissipation air duct 110, so that the heat dissipation fan 108 can supply air into the heat exchange tube 116 through the heat dissipation air duct 110, so as to cool the material containing member 112 in an air cooling manner, and reduce the risk of scalding the user by the high-temperature material containing member 112 after the cooking is completed.

Specifically, during daily use, after a user places the cooked food into the material holder 112, the food to be cooked is placed into the cooking cavity 104 together with the material holder 112; at this time, the heat exchange tube 116 of the material accommodating part 112 can be communicated with the first air outlet 158 of the heat dissipation air duct 110. Then, the cooking appliance 100 cooks the food on the material container 112.

After cooking, the temperature of the material containing member 112 is also high, and the user may risk being scalded if the user directly takes the material containing member 112. At this time, the heat dissipation fan 108 may be operated, the heat dissipation fan 108 supplies air into the heat exchange tube 116 through the first air outlet 158 of the heat dissipation air duct 110, and the air flow can exchange heat with the accommodating body 114 when passing through the heat exchange tube 116, so as to quickly reduce the temperature of the accommodating body 114.

In this way, on one hand, the temperature of the containing body 114 can be reduced through the air flow, the risk of scalding the user by the material containing piece 112 is reduced, and on the other hand, the user can take out the material containing piece 112 in a short time under the condition that the user does not wear gloves, so that the meal taking time of the user can be greatly shortened. Meanwhile, the temperature of the accommodating body 114 can be quickly reduced by the air flow in the heat exchange tube 116, so that the tabletop or the counter surface cannot be scalded when the accommodating body 114 is placed on the tabletop or the counter surface.

In addition, since the heat exchange tube 116 is disposed on the accommodating body 114, that is, the object to be cooled is the accommodating body 114 instead of the cooking cavity 104 of the cooking appliance 100, and the cooling medium is air flow, the temperature in the cooking cavity 104 is less affected by the medium in the heat exchange tube 116, so that the controllability of the temperature of the food can be ensured, and the accurate positioning is achieved, only the accommodating body 114 is cooled, but the food cannot be cooled. The user is facilitated to remove the material holding member 112 without wearing protective gloves.

In addition, the invention selects air as a heat dissipation medium to cool the containing body 114 and the material containing piece 112, the source of the air is wide and the air is infinite, so that the cold air can be continuously adopted to cool the material containing piece 112, the air cooling mode is more environment-friendly, and the air after heat exchange can be directly discharged into the external environment.

Therefore, the cooking appliance 100 provided by the invention can cool the material containing member 112 in an air cooling manner, so that the material containing member 112 is quickly cooled to a proper temperature (i.e. the temperature of a user cannot be scalded) after cooking is finished, and the user can directly take the material containing member 112 and cannot be scalded. Therefore, on one hand, the risk of scalding the user is reduced, and on the other hand, the defect that the user needs to wear gloves and other holding parts for holding materials in the related art is overcome, so that the user can use the glove conveniently in daily life.

A second embodiment of the present invention proposes a cooking appliance 100, further based on the first embodiment:

When the user places the material containing member 112 in the cooking cavity 104, the inlet end 122 of the heat exchange tube 116 can be communicated with the first air outlet 158 through the first opening 118, so that the air flow in the heat dissipation air duct 110 enters the heat exchange tube 116 through the first opening 118.

When the user places the material containing member 112 in the cooking cavity 104, the outlet end 124 of the heat exchange tube 116 can be communicated with the external environment through the second opening 120, so that the air flow after heat exchange is discharged through the second opening 120. In this way, the heat dissipation fan 108 can continuously provide the air flow with relatively low temperature to the heat exchange tube 116, so as to continuously cool the accommodating body 114, and increase the cooling speed.

Specifically, as shown in fig. 1, the side wall of the cooking cavity 104 is provided with a mounting structure (not shown in the drawing), and the mounting structure is positioned to be opposite to the first opening 118 and the second opening 120. In this way, by designing the positions of the mounting structure, the first opening 118 and the second opening 120, it is ensured that the material containing member 112 is mounted on the mounting structure, the inlet end 122 of the heat exchange tube 116 is communicated with the first opening 118, and the outlet end 124 of the heat exchange tube 116 is communicated with the second opening 120.

In particular, the mounting structure may be a mounting bead, a mounting groove, etc., which are not discussed in detail herein.

In addition, the cooking appliance 100 provided in this embodiment has all the advantages of the cooking appliance 100 of the first embodiment, and can enable the material containing member 112 to be quickly reduced to a proper temperature after cooking is finished, so that a user can directly take the material containing member 112 and is not scalded, the risk of scalding the user is reduced, and the user does not need to wait for a long time without finding gloves; the heat dissipation mode is more environment-friendly, and air subjected to heat exchange can be directly discharged into the external environment and is not discussed in detail herein.

A third embodiment of the present invention proposes a cooking appliance 100, further based on the first embodiment and the second embodiment:
