[0002] As a kitchen appliance, a steaming box can be used for pure steaming during food cooking to achieve the purpose of healthy cooking without open fire and with less fumes. However, the steaming box does not have a refrigeration function for food. In addition, the poor heat dissipation of the refrigeration system and evaporator of the steaming box affects the cabinet and is also likely to cause discomfort to the human body. Therefore, the structural cooperation setting of the refrigeration system and evaporator of the steaming box is particularly important; a refrigeration system will be installed in the steaming box to reduce the temperature of the steam discharged from the inner container.

[0003] At present, the refrigeration systems commonly used in the prior art for heat dissipation of steaming boxes include a generating tray, a blower, a water receiving tray and a condensing pipe. The steam is introduced into the generating tray, and the blower is used for heat dissipation and cooling to achieve temperature reduction.

[0004] The above refrigeration system is installed outside the steaming box, and such a structure is also commonly used in the installation structure of the refrigeration system in the prior art. The heat dissipation effect of the above structure relying on a single blower is poor, and it cannot have a refrigeration effect on the steaming box. Moreover, the slow heat dissipation speed causes discomfort to the human body. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the defects that the refrigeration system cannot refrigerate the steaming box and has poor heat dissipation effect, and provide a steaming box.

[0006] The utility model solves the above technical problem through the following technical solutions:

[0007] A steaming box includes an inner container and a refrigeration system. The refrigeration system is arranged outside the inner container and includes an evaporator; a heat dissipation chamber for accommodating the evaporator is provided on the outer side wall of the inner container.

[0008] One end of the heat dissipation chamber is communicated with the inner container through a first connecting pipe, and the other end of the heat dissipation chamber is communicated with the inner container through a second connecting pipe. The gas in the inner container enters the heat dissipation chamber through the first connecting pipe, is cooled by the evaporator, and then flows back to the inner container through the second connecting pipe.

[0009] In this solution, a heat dissipation chamber for accommodating the evaporator is provided on the outer side wall of the inner container, which is beneficial to dissipating heat from the evaporator and then dissipating heat from the inner container. One end of the heat dissipation chamber is communicated with the inner container through a first connecting pipe, and the other end of the heat dissipation chamber is communicated with the inner container through a second connecting pipe. The gas in the inner container enters the heat dissipation chamber through the first connecting pipe and is cooled by the evaporator, and then flows back into the inner container through the second connecting pipe. The above setting enables the high-temperature steam not to be discharged from the steam box, but to be cooled near the side wall of the inner container. Secondly, the cooled high-temperature steam flows back into the inner container to cool the inside of the inner container, further improving the cooling effect on the inner container. In addition, the evaporator is inside the heat dissipation chamber, and the high-temperature steam entering the heat dissipation chamber is cooled by the evaporator, which can prevent the high-temperature steam from further diffusing inside the steam box and can be centrally cooled, thereby improving the cooling effect of the refrigeration system.

[0010] Preferably, a blower is further provided in the heat dissipation chamber, and the blower is used to make the high-temperature steam in the inner container flow through the heat dissipation chamber.

[0015] The switching valve is connected to the inner container through a first air duct; the switching valve is connected to the condenser through a second air duct; the switching valve is connected to the blower assembly through a third air duct;

[0017] When the switching valve is switched so that the second air duct is communicated with the third air duct, the blower assembly is communicated with the condenser to dissipate heat from the condenser.

[0018] In this solution, the switching valve is connected to the inner container through the first air duct; the switching valve is connected to the refrigeration system through the second air duct; the switching valve is connected to the fan assembly through the third air duct; the above settings enable the inner container, the fan assembly, and the refrigeration system to be interconnected through the switching valve. When the switching valve switches to connect the third air duct to the first air duct, the fan assembly is connected to the inner container to discharge the steam in the inner container; the above settings are conducive to quickly discharging the steam in the inner container for heat dissipation, with convenient operation and fast heat dissipation rate. When the switching valve switches to connect the second air duct to the third air duct, the fan assembly is connected to the refrigeration system to dissipate heat from the refrigeration system. The above settings are convenient to operate and can utilize the existing fan assembly to achieve the effect of refrigerating the steam box.

[0022] In this solution, the above setting method of the second temperature sensor is conducive to monitoring the temperature of the inner container.

[0023] Preferably, a heat insulating cotton is also laid on the outer side wall of the inner container.

[0024] In this solution, the setting of the heat insulating cotton prevents the heat or cold air in the inner container from escaping during the operation of the steam box, improving its working efficiency.

[0025] Preferably, the steam box further includes a box body, and the inner container, the refrigeration system, the heat dissipation chamber, the switching valve, and the fan assembly are all arranged inside the box body.

[0063] In this embodiment, a heat dissipation chamber 112 for accommodating the evaporator 124 is provided on the outer side wall of the inner container 11, which is beneficial to dissipate heat from the evaporator 124, and then dissipate heat from the inner container 11; one end of the heat dissipation chamber 112 is communicated with the inner container 11 through a first connecting pipe 1121, and the other end of the heat dissipation chamber 112 is communicated with the inner container 11 through a second connecting pipe 1122. The gas in the inner container 11 enters the heat dissipation chamber 112 through the first connecting pipe 1121 and is cooled by the evaporator 124, and then flows back to the inner container 11 through the second connecting pipe 1122. The above setting enables the high-temperature steam not to be discharged from the steaming box 1, but to be cooled near the side wall of the inner container 11. Secondly, the cooled high-temperature steam flows back into the inner container 11 to cool the inside of the inner container 11, further improving the cooling effect on the inner container 11; in addition, the evaporator 124 is inside the heat dissipation chamber 112, and the high-temperature steam entering the heat dissipation chamber 112 is cooled by the evaporator 124, which can prevent the high-temperature steam from further diffusing inside the steaming box 1 and can be centrally cooled, thereby improving the cooling effect of the refrigeration system.

In addition, the above heat dissipation chamber 112 and evaporator 124 can be provided on any outer side wall of the inner container 11. Further, on the premise of satisfying the communication between the heat dissipation chamber 112 and the inner container 11, the above first connecting pipe 1121 and second connecting pipe 1122 should be as short as possible to reduce the conveying distance of the high-temperature steam, concentrate the heat of the high-temperature steam, and thus accelerate its heat dissipation.

In this embodiment, the setting of the fan 113 enables the high-temperature steam in the inner container 11 to be forced to convect and exchange heat with the evaporator, which can quickly cool the food in the steaming box 1 and ensure the taste of the food ingredients.

[0067] It should be noted that in this embodiment, the structure of the fan 113 is only a preferred structural manner, but in other alternative embodiments, the fan 113 can also be set to any structure applicable thereto. And, in Figure 1 it shows the arrangement mode where the fan 113 is located upstream of the evaporator 124. In other embodiments, there can also be other arrangement modes so that the steam in the inner container 11 can flow through the evaporator 124.

[0068] Referring toFigure 1 It is understood that the refrigeration system includes a compressor 121, a condenser 122 and a throttle 123. The coolant enters the condenser 122, the throttle 123 and the evaporator 124 in sequence from the compressor 121 and then returns to the compressor 121.

[0069] In this embodiment, the coolant enters the condenser 122, the throttle 123 and the evaporator 124 in sequence from the compressor 121 and then returns to the compressor 121, so that the coolant can be recycled during the process of cooling the steaming box 1.

[0070] It should be noted that after the compressor 121 compresses the coolant, it enters the condenser 122 for cooling, then flows through the throttle 123, enters the evaporator 124 to cool the inner tank 11, and the used coolant returns to the compressor 121 for reuse.

[0071] Refer to Figure 1 It is understood that the steaming box 1 further includes a fan assembly 14 and a switching valve 13. The fan assembly 14 is arranged outside the inner tank 11; the switching valve 13 is connected to the inner tank 11 through a first air duct 131; the switching valve 13 is connected to the condenser 122 through a second air duct 132; the switching valve 13 is connected to the fan assembly 14 through a third air duct 133; when the switching valve 13 switches to connect the third air duct 133 with the first air duct 131, the fan assembly 14 is connected to the inner tank 11 for discharging the high-temperature steam in the inner tank 11; when the switching valve 13 switches to connect the second air duct 132 with the third air duct 133, the fan assembly 14 is connected to the condenser 122 for dissipating heat from the condenser 122.

The above settings are convenient to operate and can utilize the existing fan assembly 14 to achieve the effect of refrigerating the steaming box 1.

[0073] It should be noted that when the third air duct 133 is connected to the first air duct 131, neither the third air duct 133 nor the first air duct 131 is connected to the second air duct 132. Similarly, when the second air duct 132 and the third air duct 133 are connected, neither the third air duct 133 nor the second air duct 132 is connected to the first air duct 131.

[0075] In this embodiment, the condensing pipe 1221 is beneficial to cooling the coolant, and the setting of the temperature sensor is beneficial to monitoring the heat dissipation condition of the condenser 122 by the fan assembly 14.

[0076] It should be noted that in this embodiment, the first temperature sensor 1222 is merely a preferred component, but in other alternative embodiments, the first temperature sensor 1222 can also be set as any component suitable for this, such as a chip or a thermistor, etc.

[0077] Refer to Figure 1 It can be understood that a second temperature sensor 111 is provided on the outer side wall of the inner container 11.

[0078] In this embodiment, the setting manner of the above-mentioned second temperature sensor 111 is beneficial to monitoring the temperature of the inner container 11.

[0079] It should be noted that in this embodiment, the second temperature sensor 111 is merely a preferred component, but in other alternative embodiments, the first temperature sensor 1222 can also be set as any component suitable for this, such as a chip or a thermistor, etc.

[0080] Refer to Figure 1 It can be understood that a heat-insulating cotton is also laid on the outer side wall of the inner container 11.

[0081] In this embodiment, the setting of the heat-insulating cotton prevents the heat or cold air in the inner container 11 from flowing out when the steam box 1 is working, thereby improving its working efficiency.

[0082] It should be noted that in this embodiment, the heat-insulating cotton is merely a preferred structure, but in other alternative embodiments, the heat-insulating cotton can be set as any structure suitable for this, such as a heat-insulating cover or a heat-insulating seal, etc.

[0083] Refer to Figure 1 and Figure 2It is understood that the steam box 1 further includes a box body 15.

[0084] In this embodiment, the fan assembly 14 is arranged at the top of the box body 15 and is arranged outside the top wall of the inner liner 11. Such an arrangement is conducive to quickly discharging the heat of the box body 15 to the outside of the box body 15, and is also conducive to the heat discharged outside the box body 15 being far away from the human body; the compressor 121, the condenser 122, and the throttle 123 are arranged at the bottom of the box body 15 and are located outside the rear wall of the inner liner 11, which is conducive to making the compressor 121, the condenser 122, and the throttle 123 close to the inner liner 11, with concentrated heat dissipation and faster heat dissipation speed.

[0085] It should be noted that the fan assembly 14 is separated from the inner liner 11 and does not directly contact.

[0086] Refer to Question 1 and Figure 2 It is understood that the steam box 1 further includes a control panel 16. The control panel 16 is arranged above the box body 15 and forms a gap 114 with the inner liner 11. The gap 114 is used for the air outlet of the fan assembly 14. In this embodiment, the arrangement of the control panel 16 facilitates controlling the working state of the steam box 1; the gap 114 formed by the control panel 16 and the inner liner 11 is conducive to the discharge of the wind generated by the fan assembly 14, so as to improve the heat dissipation effect of the fan assembly 14 on the inner liner 11 and the refrigeration system.

[0087] It should be noted that the control panel 16 faces the human body, which is convenient for people to operate and can prevent the discharged steam from flowing towards the human body to the greatest extent, thereby preventing it from bringing discomfort to the human body.

The above setting makes the high-temperature steam not discharged from the steam box 1, but cooled near the side wall of the inner tank 11. Secondly, the cooled high-temperature steam flows back into the inner tank 11 to cool the inside of the inner tank 11, further improving the cooling effect on the inner tank 11; in addition, the evaporator 124 is inside the heat dissipation chamber 112, and the high-temperature steam enters the heat dissipation chamber 112 and is cooled by the evaporator 124, which can prevent the high-temperature steam from further diffusing inside the steam box 1 and can be centrally cooled, thereby improving the cooling effect of the refrigeration system.
