[0004] However, the steam oven has high energy consumption and poor user experience. Summary of the Utility Model

[0013] In this way, the liquid in the water tank flows into the liquid receiving cavity, the steam in the cooking cavity enters the air duct cavity through the exhaust cavity, and transfers heat to the liquid in the liquid receiving cavity. The steam can heat up the liquid in the liquid receiving cavity, and at the same time, the temperature of the steam drops.

[0015] In this way, the distance between the energy-saving component and the inner tank is closer, and when the steam flows to the energy-saving component, the temperature of the steam is higher, and the temperature of the liquid in the liquid chamber rises more, which is beneficial to reducing the energy consumption of the steam generator.

[0016] In some embodiments, a steam oven is provided, wherein the liquid storage chamber is located within the area surrounded by the exhaust chamber.

[0017] In this way, the contact area between the liquid holding chamber and the steam is larger, which is beneficial to the temperature increase of the liquid in the liquid holding chamber.

[0068] As described in the background art, in the related art, a steam oven includes a water box, an inner container, a steam generator and an air duct assembly. The water box is communicated with the steam generator. The steam generator heats water into steam and transports it into the inner container. The steam in the inner container flows through the air duct assembly to the outside of the steam oven. In this way, the steam is directly discharged into the kitchen space, which not only wastes energy, resulting in a large energy consumption of the steam oven and a poor user experience, but also the discharged hot steam has a high temperature, leading to a poor user experience.

[0069] To solve the above - mentioned technical problems, based on the fact that heat can be transferred from an object with a high temperature to an object with a low temperature, and liquid needs to absorb heat to generate steam. Therefore, in the steam oven provided by the embodiments of the present application, by setting an energy - saving component, the energy - saving component is configured with an adjacent liquid - holding cavity and an exhaust cavity. The exhaust cavity is communicated with the cooking cavity and also with the air duct cavity. The liquid - holding cavity is communicated with the water tank and also with the steam generator. The liquid in the water tank flows into the liquid - holding cavity. The steam in the cooking cavity enters the air duct cavity through the exhaust cavity and transfers heat to the liquid in the liquid - holding cavity. The steam can heat up the liquid in the liquid - holding cavity, and at the same time, the temperature of the steam drops. The heated liquid in the liquid - holding cavity flows to the steam generator, and the evaporator heats the liquid into steam and transports it into the cooking cavity, thereby reducing the energy consumption of the steam generator, being beneficial to reducing the overall energy consumption of the machine, and providing a high user experience. Moreover, the cooled steam is discharged to the outside of the kitchen through the air duct assembly, and its temperature is relatively low, providing a high user experience.

[0098] In some embodiments, the water tank 300 is slidably connected to the cabinet 100, and the water tank 300 slides relative to the cabinet 100 so as to be located inside or outside the cabinet 100, thereby facilitating the user to add liquid and clean the water tank 300.

[0099] In some embodiments, the outer shell 110 is configured with an access opening, the access opening communicates with the accommodation cavity, the water tank 300 is inserted into the access opening, and is slidably connected to the outer shell 110.

[0100] Specifically, the access opening is located on the front side of the outer shell 110.

[0101] It should be noted that the water tank 300 can adopt a structure of pressing and popping out or manually pulling out, and the structure of the water tank 300 will not be elaborated in this embodiment.

[0114] Specifically, the air duct assembly 500 is located on the top of the inner tank 120 .

[0115] In some embodiments, the air duct assembly 500 includes a cover plate 520 . The cover plate 520 is disposed on one side of the inner liner 120 , and the area between the cover plate 520 and the outer wall of the inner liner 120 forms an air duct cavity 510 .

[0116] Figure 6 for Figure 3 Schematic diagram of the structure of the steam oven with the cover removed.

[0117] See also Figure 6 As shown, in some embodiments, the air duct assembly 500 includes a fan 530. The fan 530 reduces the temperature of the steam by accelerating the exhaust of the steam.

[0118] The fan 530 is located on a side of the cover plate 520 away from the door body 200 , and the fan 530 is communicated with the air duct cavity 510 .

[0119] Under the action of the fan 530, the steam in the inner pot 120 is discharged to the outside of the steam oven through the air duct cavity 510.

[0122] In some embodiments, the support plate 540 is located on one side of the inner container 120. The cover plate 520 is disposed on a side of the support plate 540 away from the inner container 120, and an air duct cavity 510 is formed between the cover plate 520 and the support plate 540.

[0123] Figure 7 for Figure 6 A partial enlarged view of point C in the middle. Figure 8 for Figure 3 The schematic diagram of the structure of the steam oven after removing the air duct components. Figure 9 A schematic diagram of the structure of the energy-saving components in the steam oven provided in an embodiment of the present application.

[0124] See also Figures 7 to 9 As shown, in some embodiments, the steam oven includes an energy-saving component 600. The energy-saving component 600 is used to receive the liquid in the water tank 300, and use the liquid to absorb the heat of the steam to reduce the temperature of the steam. At the same time, the liquid can be heated, and the heated liquid can be transported to the steam generator 400 to generate steam, thereby reducing the energy consumption of the steam generator 400.

[0125] The energy-saving component 600 is located in the housing 110 , and the energy-saving component 600 is configured with a liquid storage chamber 610 . The energy-saving component 600 is configured with an exhaust chamber 620 .

[0126] Specifically, the energy-saving component 600 is located in the accommodating cavity. The energy-saving component 600 is configured with a liquid storage cavity 610 and an exhaust cavity 620 arranged adjacent to each other. The exhaust cavity 620 is communicated with the cooking cavity and the air duct cavity 510. The liquid storage cavity 610 is communicated with the water tank 300 and the steam generator 400.

[0127] It is understandable that, based on the principle that heat can be transferred from an object with a high temperature to an object with a low temperature, liquid needs to absorb heat to generate steam. The liquid in the water tank 300 flows to the liquid chamber 610, and the steam in the cooking chamber enters the air duct chamber 510 through the exhaust chamber 620, and transfers heat to the liquid in the liquid chamber 610. The steam can heat up the liquid in the liquid chamber 610, and the temperature of the steam decreases at the same time. The heated liquid in the liquid chamber 610 flows to the steam generator 400, and the evaporator heats the liquid into steam and transports it to the cooking chamber, thereby reducing the energy consumption of the steam generator 400, which is beneficial to reducing the energy consumption of the whole machine, and the user experience is higher. Moreover, the cooled steam is discharged to the outside of the kitchen through the air duct assembly 500, and the temperature is lower, and the user experience is higher.

[0128] In some embodiments, the energy-saving component 600 is located in the air duct cavity 510.

[0129] See Figure 5 As shown, in some embodiments, the energy-saving component 600 is located between the inner container 120 and the air duct component 500. In this way, the distance between the energy-saving component 600 and the inner container 120 is relatively close. When the steam flows to the energy-saving component 600, the temperature of the steam is relatively high. Thus, the temperature rise of the liquid in the liquid storage cavity 610 is relatively large, which is beneficial to reducing the energy consumption of the steam generator 400.

[0130] In some embodiments, the liquid storage cavity 610 and the exhaust cavity 620 are arranged side by side.

[0131] See Figure 5 As shown, in some embodiments, the liquid storage cavity 610 is located within the area surrounded by the exhaust cavity 620. In this way, the contact area between the liquid storage cavity 610 and the steam is relatively large, which is beneficial to the temperature rise of the liquid in the liquid storage cavity 610.

[0132] In some embodiments, in order to prevent liquid overflow, the liquid storage cavity 610 and the exhaust cavity 620 are separated from each other. That is to say, the liquid in the liquid storage cavity 610 cannot flow into the exhaust cavity 620.

[0133] In some embodiments, in order to increase the temperature of the liquid in the liquid storage cavity 610, the top of the liquid storage cavity 610 is open, and the liquid storage cavity 610 is in communication with the exhaust cavity 620.

[0134] It should be noted that in this embodiment, the shapes of the liquid storage cavity 610 and the exhaust cavity 620 are not specifically limited here.

[0135] As shown in FIG. 9, in some embodiments, the energy-saving component 600 includes: an exhaust box 630. The exhaust box 630 is used to communicate the cooking cavity and the air duct cavity 510, so that the steam in the cooking cavity flows into the air duct cavity 510, reducing the leakage of steam.

[0136] Among them, the exhaust box 630 is configured with an exhaust cavity 620.

[0137] As shown in FIG. 9, in some embodiments, the energy-saving component 600 includes: a water storage box 640. The water storage box 640 is used to hold liquid.

[0138] Among them, the water storage box 640 is located in the exhaust cavity 620, and the water storage box 640 is configured with a liquid storage cavity 610.

[0139] It can be understood that in this application, the exhaust cavity 620 is formed by the exhaust box 630, and the liquid storage cavity 610 is formed by the water storage box 640, and the overall structure is relatively simple.

[0140] It should be noted that, in some embodiments, the water storage box 640 and the exhaust box 630 are integrally provided. Alternatively, the water storage box 640 and the exhaust box 630 are separately provided.

[0141] Refer to Figure 5 As shown, in some embodiments, the inner container 120 is configured with a first opening (not shown in the figure), and the first opening communicates with the cooking cavity.

[0142] Among them, the first opening can be circular, rectangular, triangular or irregular in shape, etc.

[0143] Refer to Figure 5 and Figure 8 As shown, in some embodiments, the exhaust box 630 is connected to the outer wall of the inner container 120. The exhaust box 630 is configured with a second opening 631, and the second opening 631 communicates with the exhaust cavity 620. The first opening is opposite to the second opening 631, and the cooking cavity and the exhaust cavity 620 communicate through the first opening and the second opening 631.

[0144] Among them, the second opening 631 can be circular, rectangular, triangular or irregular in shape, etc.

[0145] Specifically, the first opening can be located at the top of the inner container 120.

[0146] Specifically, the end face of the exhaust box 630 facing the inner container 120 abuts against the outer wall of the inner container 120.

[0147] Exemplarily, the end face of the exhaust box 630 facing the inner container 120 can be bonded to the outer wall of the inner container 120, or the exhaust box 630 and the outer wall of the inner container 120 can be welded. After connection, the gap is small, which is conducive to reducing the escape of steam from the gap between the exhaust box 630 and the outer wall of the inner container 120.

[0148] It can be understood that in the communication scheme between the cooking cavity and the exhaust cavity 620 provided in the present application, there is no need to set up additional pipelines for communication, thereby simplifying the structure and reducing the space occupation.

[0149] In some embodiments, the opening size of the second opening 631 is larger than the opening size of the first opening.

[0150] It can be understood that the first opening has a small size, which is conducive to reducing the heat loss due to steam overflow during the operation of the steam oven. The second opening 631 has a large size. After the steam enters from the first opening into the second opening 631, it can enter the exhaust cavity 620 more evenly, so that the liquid in the liquid storage cavity 610 is heated more evenly.

[0151] In some embodiments, the thermal conductivity of the exhaust box 630 is less than that of the water storage box 640. In this way, when steam enters the exhaust cavity 620, less heat of the steam is transferred to the outside through the exhaust box 630, and more heat is transferred to the liquid in the water storage box 640.

[0152] Specifically, the thermal conductivity of the material of the exhaust box 630 can be less than that of the material of the water storage box 640.

[0153] Exemplarily, the material of the exhaust box 630 can be plastic or rubber.

[0154] Exemplarily, the material of the water storage box 640 can be metal, such as copper, aluminum, etc.

[0155] In some embodiments, a heat insulation member is further included, and the heat insulation member is disposed on the outer wall of the exhaust box 630.

[0156] Exemplarily, the heat insulation member can be heat insulation cotton or a heat insulation coating.

[0157] Figure 10 It is a schematic structural diagram of the exhaust box in the steam oven provided by the embodiment of the present application.

[0158] See Figure 10 As shown, in some embodiments, the exhaust box 630 is configured with a third opening 632. The third opening 632 communicates with the exhaust cavity 620. The exhaust box 630 is inserted on the air duct assembly 500, and a part of the exhaust box 630 is located in the air duct cavity 510.

[0159] Among them, the third opening 632 is located in the air duct cavity 510, and the air duct cavity 510 communicates with the exhaust cavity 620 through the third opening 632. In this way, there is no need to set up an additional pipeline to connect the exhaust cavity 620 and the air duct cavity 510, the structure is relatively simple, and the cost is relatively low.

[0160] Among them, the third opening 632 can be circular, rectangular, triangular or irregular in shape, etc.

[0161] See Figure 6 and Figure 7 As shown, the exhaust box 630 is located between the support plate 540 and the inner liner 120. In this way, the distance between the exhaust box 630 and the inner liner 120 is relatively close. When the steam flows to the exhaust box 630, the temperature of the steam is relatively high. In this way, the temperature rise of the liquid in the liquid holding cavity 610 is relatively large, which is beneficial to reducing the energy consumption of the steam generator 400.

[0162] In some embodiments, the exhaust box 630 is inserted on the support plate 540. A part of the exhaust box 630 is located in the air duct cavity 510. In this way, there is no need to set up an additional pipeline to connect the exhaust cavity 620 and the air duct cavity 510, the occupied space is relatively small, and the cost is relatively low.

[0163] In some embodiments, the exhaust box 630 includes a first part and a second part that communicate with each other. The inner walls of the first part and the second part together form an exhaust cavity 620. The second part is located at the top of the first part. A second opening 631 is located at the bottom of the first part, and a third opening 632 is located at the bottom of the second part. The bottom of the first part abuts against the outer wall of the inner container. The second part is inserted into the support plate 540.

[0164] In some embodiments, the orthographic projection of the first part onto the ground is located within the orthographic projection of the second part onto the ground.

[0165] In some embodiments, the first part may be in the shape of a rectangular body.

[0166] In some embodiments, the second part may be in the shape of a cylinder.

[0167] In some embodiments, the second opening 631 and the third opening 632 are located on opposite sides of the exhaust box 630.

[0168] Specifically, the second opening 631 is located at the bottom of the exhaust box 630. The third opening 632 is located at the top of the exhaust box 630.

[0169] In some embodiments, the opening size of the third opening 632 is smaller than the opening size of the second opening 631. In this way, the speed at which steam enters the air duct cavity 510 from the exhaust cavity 620 is slower, which is beneficial for the steam to transfer more heat to the liquid in the liquid holding cavity 610.

[0170] It should be noted that the opening size is the cross-sectional area size through which steam can flow.

[0171] See Figure 8 and Figure 9 As shown in

[0172] In some embodiments, the steam oven further includes a first pipe 700. The water tank 300 is at least partially located above the energy-saving component 600. The first pipe 700 is connected to the water tank 300 and communicates with the water storage box 640.

[0173] It can be understood that the liquid in the water tank 300 can flow to the water storage box 640 under the action of gravity, which is beneficial for reducing energy consumption.

[0174] Specifically, the first pipe 700 is inserted into the exhaust box 630 and extends into the exhaust cavity 620 to connect with the water storage box 640.

[0175] In some embodiments, the water tank 300 and the water storage box 640 are configured as a communicating vessel structure through the first pipe 700, and the liquid levels in the water tank 300 and the water storage box 640 are the same.

[0176] In some embodiments, an inlet water pump is further included. The inlet water pump is communicated with the first pipeline 700. Under the action of the inlet water pump, the liquid in the water tank 300 flows into the water storage box 640. In this way, when the liquid level in the water tank 300 is relatively low, it is still possible to transport the liquid to the water storage box 640, which is beneficial to ensuring the smoothness of water inlet.

[0177] See Figure 8 and Figure 9 As shown, in some embodiments, the steam oven further includes a second pipeline 800 and a water pump 900. The water pump 900 is communicated with the second pipeline 800. The second pipeline 800 is communicated with the water storage box 640 and is also communicated with the steam generator 400.

[0178] In this way, under the action of the water pump 900, the liquid in the water storage box 640 flows into the steam generator 400. In this way, it is beneficial to control the water inlet amount of the steam generator 400.

[0179] Specifically, the second pipeline 800 is inserted into the exhaust box 630 and extends into the exhaust cavity 620 to be connected with the water storage box 640.

[0180] In some embodiments, the steam oven further includes a fifth pipeline and a third return water pump. The third return water pump is communicated with the fifth pipeline. The fifth pipeline is communicated with the water tank 300 and is also communicated with the steam generator 400.

[0181] It can be understood that the residual water in the steam generator 400 can be pumped back into the water tank 300 through the third return water pump.

[0182] In some embodiments, the steam oven further includes a third pipeline and a first return water pump. The first return water pump is communicated with the third pipeline. The third pipeline is communicated with the water storage box 640 and is also communicated with the steam generator 400.

[0183] It can be understood that the residual water in the steam generator 400 can be pumped back into the water storage box 640 through the first return water pump.

[0184] In some embodiments, the steam oven further includes a fourth pipeline and a second return water pump. The second return water pump is communicated with the fourth pipeline. The fourth pipeline is communicated with the water storage box 640 and is also communicated with the water tank 300.

[0185] It can be understood that the residual water in the steam generator 400 can be pumped back into the water storage box 640 through the second return water pump.
