[0016] A first communication port is provided on the side wall of the storage box, and the first open end of the heat-conducting pipe is connected with the pump body through the first communication port;

[0017] The second communication port is arranged at another position on the side wall of the storage box, and the second communication port is connected to the second open end of the heat conduction pipe.

[0018] The heat pipe comprises:

[0019] a coiled section, laid in close contact with at least one side surface of the shell, the coiled section having a first open end and a second open end corresponding to the first communication port and the second communication port respectively;

[0020] Two connecting sections, one of the two connecting sections is used to connect the first opening end and the first communicating port, and the other connecting section is used to connect the second opening end and the second communicating port.

[0021] The first opening end and / or the second opening end is the lowest point of the refrigeration channel.

[0022] The centroid of the first opening end and the centroid of the second opening end are both located above the storage box.

[0023] The storage box comprises:

[0024] A refrigeration component is disposed in the storage box, and the refrigeration component is in contact with the refrigeration medium;

[0025] A temperature sensing element is arranged in the storage box, the temperature sensing element is in contact with the refrigerant medium, and in a cooling state, when the temperature of the refrigerant medium reaches a preset threshold, the pump body is controlled to operate.

[0032] The heat conducting pipe is arranged in contact with three surfaces of the shell.

[0033] The technical solution of the present invention has the following advantages:

[0034] 1. A steam oven provided by the present invention comprises: a steam oven chamber, comprising a shell for enclosing a steam oven space; a heating assembly for heating the shell; and a refrigeration unit, which is arranged in close contact with the shell and has a cooling state for absorbing heat from the shell and a normal temperature state for stopping absorbing heat from the shell.

[0035] When the user uses the reservation function, the ingredients to be steamed and baked are placed in a relatively closed steaming and baking chamber. At this time, the refrigeration part switches to a cooling state, absorbing the heat of the shell, lowering the temperature of the shell, thereby lowering the temperature inside the steaming and baking chamber, preventing the ingredients from deteriorating during the reserved time waiting for steaming and baking.

[0036] 2. The present invention provides a steam oven, wherein the refrigeration part comprises: a heat-conducting pipe, which is made of a heat-conducting material, and is arranged in contact with the shell. The heat-conducting pipe has a refrigeration channel for the flow of a refrigeration medium; and a pump body, which works when the refrigeration part is in a cooling state, and drives the refrigeration medium to enter the heat-conducting pipe and circulate in the heat-conducting pipe.

[0037] The heat pipe is attached to the outside of the shell, and heat is exchanged with the shell through the refrigerant medium, so that the heat of the shell is taken away by the refrigerant medium, so as to achieve the purpose of lowering the temperature of the shell and then lowering the temperature inside the steaming and baking chamber. Among them, the pump body provides power for the circulation of the refrigerant medium, and the flowing refrigerant medium can more efficiently take away the heat of the shell, thereby improving the efficiency of refrigeration.

[0038] 3. The present invention provides a steam oven, wherein the refrigeration part further includes: a storage box for accommodating the refrigeration medium; a first connecting port, provided on the side wall of the storage box, through which the first open end of the heat-conducting pipe is connected to the pump body; and a second connecting port, provided at another position on the side wall of the storage box, wherein the second connecting port is connected to the second open end of the heat-conducting pipe.

[0039] The refrigerant is stored in the storage box. When the refrigeration unit is turned on to cool down, the refrigerant is pumped into the heat pipe through the pump. The heat pipe has two openings. The refrigerant enters the heat pipe from one opening and then re-enters the storage box from the other opening. When the refrigeration unit is switched to normal temperature, the pump stops working and the refrigerant returns to the storage box by gravity.

[0040] 4. The present invention provides a steam oven, wherein the heat-conducting pipe comprises: a coiled section, which is laid in contact with at least one side of the shell, and has a first open end and a second open end corresponding to the first connecting port and the second connecting port respectively; and two connecting sections, one of the two connecting sections is used to connect the first open end and the first connecting port, and the other connecting section is used to connect the second open end and the second connecting port.

[0041] The connecting section is used to connect the refrigeration channel and the storage box. Since the heat pipe is made of heat-conducting material, when the steam oven is used for steaming and baking, the heat pipe will be heated by the shell, thereby affecting the refrigeration medium inside the shell. In this solution, the connecting section is made of heat-insulating material to prevent the heat pipe from transferring heat to the storage box when the temperature rises, thereby affecting the temperature of the refrigeration medium inside the storage box.

[0042] 5. In a steam oven provided by the present invention, the first opening end and / or the second opening end is the lowest point of the refrigeration channel.

[0043] The first opening end and the second opening end serve as two openings of the refrigeration channel. When the pump body stops working, the refrigeration medium flows back into the storage box from both openings. Since the refrigeration medium flows by gravity, the first opening end and / or the second opening end located at the lowest point of the refrigeration channel makes it easier for the refrigeration medium to flow back into the storage box.

[0044] 6. In the steam oven provided by the present invention, the centroid of the first opening end and the centroid of the second opening end are both located above the storage box.

[0045] The first opening end and the second opening end correspond to the end faces of the two openings of the refrigeration channel respectively. Since there is a certain hydraulic pressure in the storage box, a liquid column of a certain height will exist in the connecting section. In order to prevent the refrigerant medium from contacting the refrigeration channel and being heated, the height of the opening end of the refrigeration channel in this solution is higher than the storage box.

[0046] 7. The present invention provides a steam oven, wherein the storage box comprises: a refrigeration component, which is arranged in the storage box and is in contact with the refrigeration medium; a temperature sensing component, which is arranged in the storage box and is in contact with the refrigeration medium, and in a cooling state, when the temperature of the refrigeration medium reaches a preset threshold, the pump body is controlled to operate.

[0047] In the cooling state, the refrigeration component first cools down the refrigerant medium, and then starts the pump body when the refrigerant medium is lower than the shell temperature, driving the refrigerant medium to flow into the heat transfer pipe, thereby taking away the heat of the shell and achieving the purpose of refrigeration insurance.

[0048] 8. In a steam oven provided by the present invention, the storage box further comprises: a partition, which separates the interior of the storage box into a refrigeration chamber for accommodating the refrigeration component, and the partition is provided with a passage connecting to other spaces in the storage box, and the refrigeration chamber is located between the first connecting port and the second connecting port.

[0049] The first connecting port and the second connecting port are used for the outflow and inflow of the refrigerant respectively. The refrigeration chamber is located on the final path of the refrigerant circulation, so that the refrigerant that absorbs heat can more fully contact and exchange heat with the refrigeration element, and the temperature is lowered again to form a cycle. The partition guides the refrigerant to flow into the refrigeration chamber and plays a guiding role.

[0050] 9. In a steam oven provided by the present invention, the value of the angle A between the heat conduction pipe and the horizontal plane is [0°, 90°].

[0051] The heat conducting pipe can be wound in a vertical direction and attached to the outside of the shell, or can be wound in a horizontal direction and attached to the outside of the shell.

[0052] 10. In the steam oven provided by the present invention, the heat conducting pipe is laid on the shell in an inclined coil.

[0053] The heat conducting pipe is inclined and coiled, and when the pump body stops working, the refrigerant medium can flow back to the storage box faster along the inclined heat conducting pipe.

[0054] 11. In the steam oven provided by the present invention, the heat conducting pipe is arranged to fit three surfaces of the shell.

[0055] The heat pipes are arranged to fit the sides of the multiple shells, so that the heat of the shells can be absorbed more quickly, thereby achieving the purpose of cooling and insurance more quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0068] Example 1

[0069] A steam oven comprises: a steam oven chamber, comprising a shell 1 for enclosing a steam oven space; a heating assembly 2 for heating the shell 1; and a refrigeration unit 3, which is arranged in close contact with the shell 1 and has a cooling state for absorbing heat from the shell 1 and a normal temperature state for stopping absorbing heat from the shell 1. When a user uses a reservation function, food to be steamed and baked is placed in a relatively closed steam oven chamber, and at this time, the refrigeration unit 3 switches to a cooling state, absorbs heat from the shell 1, and reduces the temperature of the shell 1, thereby reducing the temperature inside the steam oven chamber, and preventing the food from deteriorating during the reserved time of waiting for steaming and baking.

[0070] There is no specific limitation on the structure of the refrigeration unit 3. In this embodiment, Figure 1 As shown, the refrigeration unit 3 includes: a heat pipe 31, which is made of a heat-conducting material and is arranged in close contact with the shell 1. The heat pipe 31 has a refrigeration channel for the flow of the refrigeration medium; a pump body 33, which works when the refrigeration unit 3 is in a cooling state, driving the refrigeration medium to enter the heat pipe 31 and circulate in the heat pipe 31. The heat pipe 31 is attached to the outside of the shell 1, and heat is exchanged with the shell 1 through the refrigeration medium, so that the heat of the shell 1 is taken away by the refrigeration medium, so as to achieve the purpose of lowering the temperature of the shell 1 and then lowering the temperature inside the steaming and baking chamber. Among them, the pump body 33 provides power for the circulation of the refrigeration medium, and the flowing refrigeration medium can more efficiently take away the heat of the shell 1, thereby improving the efficiency of refrigeration.

[0071] There is no specific restriction on the location of the heat pipe 31. In this embodiment, Figure 2 As shown, the heat pipe 31 is arranged in contact with the outside of the shell 1. As an alternative embodiment, the heat pipe 31 can also be arranged inside the shell 1, that is, the heat pipe 31 is arranged in the steaming and baking chamber.

[0072] There is no specific restriction on the storage and flow of the refrigerant. In this embodiment, Figure 2 , Figure 3 As shown, the refrigeration unit 3 further includes: a storage box 32 for accommodating a refrigerant; a first communication port 321 provided on the side wall of the storage box 32, through which the first opening end 313 of the heat pipe 31 is connected to the pump body 33; a second communication port 322 provided at another position on the side wall of the storage box 32, and the second communication port 322 is connected to the second opening end 314 of the heat pipe 31. The refrigerant is stored in the storage box 32. When the refrigeration unit 3 is turned on to the cooling state, the refrigerant is pumped into the heat pipe 31 through the pump body 33. The heat pipe 31 has two openings. The refrigerant enters the heat pipe 31 from one of the openings, and then re-enters the storage box 32 from the other opening. When the refrigeration unit 3 is switched to the normal temperature state, the pump body 33 stops working, and the refrigerant returns to the storage box 32 by gravity.

[0073] There is no specific limitation on the shape of the storage box 32. Figure 3 As shown, the storage box 32 is rectangular. As an alternative embodiment, the storage box 32 is square or cylindrical.

[0074] There is no specific limitation on the structure of the heat pipe 31. In this embodiment, Figure 2 , Figure 4 As shown, the heat pipe 31 includes: a coiled section 312, which is laid in contact with at least one side of the shell 1, and the coiled section 312 has a first open end 313 and a second open end 314 corresponding to the first connecting port 321 and the second connecting port 322 respectively; two connecting sections 311, one of the two connecting sections 311 is used to connect the first open end 313 and the first connecting port 321, and the other connecting section 311 is used to connect the second open end 314 and the second connecting port 322. The connecting section 311 is used to connect the refrigeration channel and the storage box 32. Since the heat pipe 31 is made of heat-conducting material, when the steaming and baking cooking is carried out inside the steam oven, the heat pipe 31 will be heated by the shell 1, thereby affecting the refrigeration medium inside the shell 1. In this solution, the connecting section 311 is made of heat-insulating material to prevent the heat pipe 31 from transferring heat to the storage box 32 when the temperature rises, thereby affecting the temperature of the refrigeration medium inside the storage box 32.

[0075] The refrigeration channel is the portion corresponding to the coiled section 312 between the first opening end 313 and the second opening end 314, and the first opening end 313 and / or the second opening end 314 are the lowest points of the refrigeration channel. The first opening end 313 and the second opening end 314 are two openings of the refrigeration channel. When the pump body 33 stops working, the refrigeration medium flows back into the storage box 32 from both openings. Since the refrigeration medium flows by gravity, the first opening end 313 and / or the second opening end 314 located at the lowest point of the refrigeration channel make it easier for the refrigeration medium to flow back into the storage box 32.

[0076] There is no specific limitation on the positional relationship between the coiled section 312 and the storage box 32. Figure 4 As shown, the centroid of the first open end 313 and the centroid of the second open end 314 are both located above the storage box 32. The first open end 313 and the second open end 314 correspond to the end faces of the two openings of the refrigeration channel respectively. Since there is a certain hydraulic pressure in the storage box 32, there will be a liquid column of a certain height in the connecting section 311. In order to prevent the refrigerant from contacting the refrigeration channel and being heated, the height of the opening end of the refrigeration channel in this solution is higher than the storage box 32. Among them, the centroid is the center of the end face shape corresponding to the first open end 313 and the second open end 314. When the cross section of the winding section 312 is circular, the centroid is the center of the circle. When the cross section of the winding section 312 is square or rectangular, the centroid is the intersection of the diagonals of the square or rectangle.

[0077] There is no specific limitation on the structure inside the storage box 32. Figure 2 , Figure 3 The storage box 32 includes: a refrigeration element 34, which is arranged in the storage box 32 and contacts the refrigeration medium; a temperature sensing element 35, which is arranged in the storage box 32 and contacts the refrigeration medium. In the cooling state, when the temperature of the refrigeration medium reaches a preset threshold, the pump body 33 is controlled to work. In the cooling state, the refrigeration element 34 first cools the refrigeration medium, and then starts the pump body 33 when the refrigeration medium is lower than the temperature of the shell 1, driving the refrigeration medium to flow into the heat conducting pipe 31, thereby taking away the heat of the shell 1, and achieving the purpose of refrigeration insurance.

[0078] There is no specific restriction on the distribution of the internal structure of the storage box 32. The storage box 32 also includes: a partition 323, which separates the storage box 32 into a refrigeration chamber for accommodating the refrigeration element 34. The partition 323 is provided with a passage connecting other spaces in the storage box 32. The refrigeration chamber is located between the first connecting port 321 and the second connecting port 322. The first connecting port 321 and the second connecting port 322 are used for the outflow and inflow of the refrigerant medium, respectively. The refrigeration chamber is located on the final path of the refrigerant medium circulation, so that the refrigerant medium that absorbs heat can more fully contact and exchange heat with the refrigeration element 34, and the temperature is reduced again to form a cycle. The partition 323 guides the refrigerant medium to flow to the refrigeration chamber and plays a guiding role. Among them, in this embodiment, the partition 323 is arranged perpendicular to the bottom surface of the storage box 32 and the side wall of the storage box 32. As an alternative embodiment, the partition 323 is inclined relative to the side wall of the storage box 32 to form a guide surface for guiding the refrigerant medium to flow to or out of the refrigeration chamber.

[0079] There is no specific limitation on the coiling method of the heat conducting pipe 31. Figure 2 As shown, the value of the angle A between the heat pipe 31 and the horizontal plane is [0°, 90°]. The heat pipe 31 can be wound vertically and attached to the outside of the housing 1, or can be wound horizontally and attached to the outside of the housing 1. As an alternative embodiment, Figure 4 As shown, the heat conducting pipe 31 is laid on the housing 1 in an inclined coil. When the pump body 33 stops working, the refrigeration medium can flow back to the storage box 32 faster along the inclined heat conducting pipe 31.

[0080] There is no specific restriction on the distribution position of the heat pipe 31. In this embodiment, Figure 1 , Figure 2 As shown, the heat pipe 31 is arranged to fit three surfaces of the shell 1. The heat pipe 31 is arranged to fit multiple sides of the shell 1, which can absorb the heat of the shell 1 more quickly and achieve the purpose of cooling and insurance more quickly. As an alternative embodiment, the heat pipe 31 is correspondingly distributed on one side of the shell 1.

[0081] There is no specific limitation on the distribution structure of the heat pipe 31. In this embodiment, Figure 2 As shown, the heat conducting pipe 31 fits three sequentially connected side surfaces of the shell 1 to form a "C"-shaped structure surrounding and fitting the outer surface of the shell 1, and the opening of the "C"-shaped structure faces the opening of the steaming and baking chamber.

[0082] There is no specific limitation on the connection structure between the heat pipe 31 and the housing 1. In this embodiment, Figure 4 As shown, the limiting member 4 is arranged on the outer side of the housing 1 and surrounds the housing 1 to form a limiting slot 42 for the heat conducting pipe 31 to be inserted. The opening of the limiting slot 42 is provided with a guiding inclined surface 41 to guide the heat conducting pipe 31 into the limiting slot 42. As an alternative embodiment, the heat conducting pipe 31 is directly welded to the outer side of the housing 1.

[0083] There is no specific limitation on the connection method between the stopper 4 and the housing 1. In this embodiment, one end of the stopper 4 is welded to the outside of the housing 1, and an opening for the heat pipe 31 to be embedded is formed between the other end and the housing 1. As an alternative embodiment, the stopper 4 is detachably fixed to the outside of the housing 1 by screws and nuts, or is installed on the outside of the housing 1 by buckles.

[0084] There is no specific limitation on the number of the limiting members 4. In this embodiment, the limiting members 4 are evenly distributed along the extension direction of the winding section 312. As an alternative embodiment, the limiting members 4 are only provided on two side surfaces of the housing 1.

[0085] There is no specific limitation on the distribution structure of the heat pipe 31 and the heating assembly 2. Figure 2 As shown, the heating components 2 are distributed on two outer surfaces of the housing 1 that are opposite to each other in the vertical direction. The heat pipes 31 are provided on three outer surfaces of the housing 1 that are connected in sequence in the horizontal direction. When the heating components 2 are working, the heat is convected in the vertical direction to heat the food. When the refrigeration unit 3 is working, the heat pipes 31 surround the housing in the horizontal direction and work to absorb heat and cool at the same time.

[0086] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
