Therefore, in order to release the hot air in the installation cavity to the outside, the shell is provided with the air inlet and the air outlet, so that the heat flow in the installation cavity can flow out, and the outside cold air can flow into the installation cavity.

In the existing oven, a heat dissipation system is further arranged in the installation cavity and comprises a heat dissipation fan and a heat dissipation air duct. The air inlet of the heat dissipation fan is communicated with the installation cavity, the air outlet of the heat dissipation fan is communicated with the heat dissipation air channel, and the heat dissipation air channel is also communicated with the air outlet. When the heat dissipation system dissipates heat, hot air in the installation cavity is sucked from the air inlet of the heat dissipation fan, flows to the heat dissipation air duct through the air outlet of the heat dissipation fan, and is finally discharged out of the shell. Meanwhile, outside cold air continuously enters the installation cavity from the air inlet of the shell, and the temperature in the installation cavity is guaranteed to be within a normal range, so that stable work of the electrical component is guaranteed, and the service life of the electrical component is guaranteed.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The embodiment of the application provides an oven which can be used for baking food. Illustratively, embodiments of the present application provide a dual-cavity oven, i.e., having two cooking cavities for cooking food. Of course, the oven of the embodiment of the present application may also be a single-cavity oven.

Referring to fig. 1 and 2, an oven provided by the embodiment of the present application includes an oven body 1, an inner container 2, a first electrical component 31, a second electrical component 32, a first heat dissipation system 4, and a second heat dissipation system 5.

As shown in FIG. 1, the box 1 encloses a chamber, and the box 1 is provided with an air inlet 15 and an air outlet 16. The cabinet 1 includes a cabinet top plate 11, cabinet side plates 12, a cabinet back plate (a cabinet back plate 13 shown in fig. 4), and a door 14. As shown in fig. 1, in the oven provided by the embodiment of the present application, the door 14 includes a first door 141 and a second door 142.

The box body 1 is provided with an air inlet 15 and an air outlet 16. The hot air in the cabinet 1 may be discharged to the outside through the air outlet 16, and the cold air from the outside may be introduced into the cabinet 1 through the air inlet 15. By providing the air inlet 15 and the air outlet 16, smooth circulation of air is ensured.

As shown in fig. 2, fig. 2 is a schematic structural view of the inside of the case. The inner container 2 is positioned in the cavity, and the inner part of the inner container 2 forms a baking cavity. In the oven provided by the embodiment of the present application, the inner container 2 includes a first inner container 21 and a second inner container 22, which respectively form two independent oven cavities.

As shown in fig. 2, the two inner containers are arranged at intervals along the height direction X of the oven. Taking the second inner container 22 as an example, the second inner container includes a top panel 221, a back panel 222, side panels and a bottom panel (not shown in the figure) to enclose the baking cavity. It is understood that the first inner container 21 also has the same structure as described above to enclose the baking chamber.

Wherein, the backplate and the box of inner bag enclose into first accommodation space, and the roof and the box of inner bag enclose into second accommodation space. For example, taking the oven shown in fig. 2 as an example, the back panel of the second inner container 22 and the back panel of the first inner container 21 and the box body enclose a first accommodating space. The top plate of the first inner container 21 and the box body enclose a second accommodating space.

It should be noted that the above description is made by taking an example in which the oven has two inner containers. Similarly, when the oven only has one inner container, the back plate and the top plate of the inner container and the box body respectively enclose the first accommodating space and the second accommodating space.

As shown in fig. 2, the first electrical component 31 is located in the first receiving space, and the second electrical component 32 is located in the second receiving space. The first electrical component 31 and the second electrical component 32 are electrical components required for ensuring the normal operation of the oven.

In the oven provided by the embodiment of the present application, the first heat dissipation system 4 is configured to dissipate heat of the first accommodating space, and the second heat dissipation system 5 is configured to dissipate heat of the second accommodating space.

The oven that this application embodiment provided is equipped with first cooling system 4 and dispels the heat to first accommodation space, and second cooling system 5 dispels the heat to second accommodation space. Since the first accommodating space and the second accommodating space are respectively provided with the heat dissipation systems for heat dissipation, both the first electrical component 31 located in the first accommodating space and the second electrical component 32 located in the second accommodating space can be sufficiently dissipated, so that the first electrical component 31 and the second electrical component 32 can stably operate.

Compared with the prior art, the oven that this application embodiment provided, dispel the heat to first accommodation space and second accommodation space respectively through first cooling system 4 and second cooling system 5, the holistic radiating effect of oven has been improved, first electrical components 31 in the first accommodation space and second electrical components 32 in the second accommodation space can both obtain effectual heat dissipation, first electrical components 31 and second electrical components 32 temperature have been guaranteed normally, make it can last steady operation, guarantee its life.

As shown in fig. 2 and 3, a heat insulating plate 6 is further provided above the first liner 21 to block heat transferred upward from the first liner, thereby achieving a heat insulating effect. Wherein, as shown in fig. 3, a space between the heat insulating board 6 and the top plate 11 of the cabinet is a second receiving space.

As shown in fig. 1, an operation panel 7 is further provided above the door 14, and the oven can be manually operated by the operation panel 7 to control the operation and stop of the oven.

In some embodiments, as shown in fig. 2, the first heat dissipation system 4 includes a first fan 41 and the second heat dissipation system 5 includes a second fan 51. The first fan 41 and the second fan 51 are both located in the first accommodation space or the second accommodation space, respectively.

The first fan 41 and the second fan 51 can increase the flow speed of the air flow, and timely send out the hot air in the first accommodating space and the second accommodating space through the air outlet 16. Cold air can be supplemented into first accommodation space and second accommodation space from air inlet 15 faster to carry out the heat transfer with first electrical components 31 and second electrical components 32, guarantee the radiating effect. The first fan 41 and the second fan 51 are selectively arranged in the first accommodating space or the second accommodating space, so that the whole structure of the oven is more compact, and the installation space is saved.

For example, the first fan 41 may be a crossflow fan, and the second fan 52 may be a centrifugal fan.

In some embodiments, the first fan 41 and the second fan 51 are located in the second accommodation space. As shown in fig. 2, the second accommodating space is located above the first liner 21. In practice, the space above the first inner container 21 is relatively large compared with other places, so that the installation is convenient. The first fan 41 and the second fan 51 are thus selectively disposed in the second accommodation space.

In some embodiments, as shown in fig. 2, the first heat dissipation system 4 further includes a first air duct assembly 42, and the first air duct assembly 42 forms a first air duct 421. The first air duct 421 has a first air inlet 4211 and a first air outlet 4212, the first air outlet 4212 is communicated with an air inlet of the first fan 41, the first air inlet 4211 is communicated with the first accommodating space, and an air outlet of the first fan 42 is communicated with an air outlet (the air outlet 16 shown in fig. 1). Further, as shown in fig. 1, the air inlet 15 includes a first air inlet 151, and the first air inlet 151 communicates with the first receiving space.

Based on the above scheme, the external cold air enters the first accommodating space through the first air inlet 151, exchanges heat with the first electrical component 31, and reduces the temperature of the first electrical component 31. Then, the hot air after heat exchange enters the first air duct 421 through the first air inlet 4211 under the action of the first fan 41. Subsequently, the hot air is discharged from the air outlet 16 communicating with the air outlet of the first fan 41. Therefore, the first electrical component 31 in the first accommodating space is in a normal temperature environment, and long-term stable operation of the first electrical component is guaranteed.

It should be noted that the first air duct assembly 42 may not be provided. As shown in fig. 2, the air inlet direction of the first fan 41 is downward, and the hot air in the first accommodating space can be directly sucked by the first fan 41. In contrast, by arranging the first air duct assembly 42 and forming the first air duct 421, the part located in the first air duct 421 can be sufficiently cooled, and meanwhile, by arranging the air duct with a certain length, a good cooling effect can be achieved at a position far away from the position of the first fan 41.

In some embodiments, as shown in fig. 2, the first electrical component 31 includes a first sub-electrical component 311 and a second sub-electrical component 312, and the first sub-electrical component 311 is located in the first air duct 421. It should be noted that the first sub-electrical component 311 is an electrical component that needs to dissipate heat, and the second sub-electrical component 312 is an electrical component that does not need much heat dissipation.

For example, the first sub-electrical component 311 is a motor of a hot air blower in the oven cavity, and needs to dissipate heat in time, otherwise, the first sub-electrical component fails due to high temperature and cannot operate. The first sub-electrical component 311 may also be a component directly connected to the heating tube, and when the temperature is too high, the component may be damaged, which may affect the use of the oven. As shown in fig. 2, the second sub-electrical component 312 may be a steam generating device, which has a higher temperature during the steam generating process, and the heat generated by the steam generating device raises the temperature of the peripheral area, and is disposed outside the first air duct 421 and separated from the first sub-electrical component 311 in the first air duct 421, so as to reduce the influence of the heat generated by the steam generating device on the first sub-electrical component 311.

Because the first sub-electrical component 311 is in the first air duct 421, the cold air exchanges heat with the first sub-electrical component 311 in the first air duct 421, so as to reduce the temperature of the first sub-electrical component 311, and ensure that the first sub-electrical component 311 can obtain a good heat dissipation effect.

In some embodiments, as shown in FIG. 2, the first air duct assembly 42 includes a first partition 422a and a second partition 422 b. The first and second spacers 422a and 422b are respectively located at opposite sides of the first sub-electrical component 311. The first partition 422a, the second partition 422b, the box (the box back 13 in fig. 4), and the back of the inner container 2 (the first inner container 21 and the second inner container 22) together enclose a first air duct 421.

The first and second partitions 422a and 422b are provided, and the air duct is formed by the back plates of the case and the inner container. The cold air entering into the first air channel can directly contact with the box body to cool the box body, and the temperature of the box body is prevented from being too high.

For example, as shown in fig. 2, the first and second partitions 422a and 422b may have the same structure. For example, the first partition 422a includes two oppositely disposed side partition plates and one bottom partition plate. The two side partition plates are respectively positioned at two opposite sides of the bottom partition plate to form a groove. Of course, the first and second partitions 422a and 422b may include only one bottom partition plate, and the two bottom partition plates are spaced apart to form the first air passage.

In some embodiments, as shown in fig. 1, the first air inlet 151 is provided on the case side plate 12. Since the oven is generally placed against a wall, and one side of the oven is placed against the wall (i.e., the case back 13 in fig. 4), air circulation is poor. With first air inlet 151 setting on curb plate 12, the circulation of air effect is better, and the entering into in the box 1 that cold air can be more smooth.

As shown in fig. 2, the first inlet vent 4211 is disposed on the first partition 422a, and the first partition 422a and the first inlet vent 151 are located on the same side of the first sub-electric element 311.

As can be seen from fig. 1 and 2, the first air inlet 151 of the case side plate 12 is located at one side of the first sub-electrical component 311, and the cool air enters the first receiving space from the side of the first sub-electrical component 311. And the first partition 422a and the first inlet port 151 are located on the same side of the first sub-electric element 311. Accordingly, the first air inlet 4211 is disposed on the first partition 422a to facilitate the entry of the cool air into the first air passage 421.

In some embodiments, the number of the first air inlets 4211 is multiple, and the multiple first air inlets 4211 are located on a side of the first sub-electrical component 311 away from the first fan 41. The plurality of first air inlets 4211 are arranged at intervals along the extending direction of the first partition 422 a.

Because the first air inlet 4211 is located at a side of the first sub-electrical component 311 away from the first fan 41, the cold air passes through the first sub-electrical component 311 first and exchanges heat with the first sub-electrical component 41 when moving towards the first fan 41. The hot air after heat exchange enters the first fan 41 again, and is discharged through the air outlet 16. Through setting up a plurality of air intakes, can increase air inlet efficiency for first sub-electrical component 311 can obtain abundant heat transfer, avoids the heat transfer inadequately to arouse the temperature rising of first sub-electrical component 311.

In some embodiments, as shown in fig. 2, the first heat dissipation system 4 further includes a second air duct assembly 43, and the second air duct assembly 43 is located in the second accommodating space. The second air duct assembly 43 forms a second air duct. The second air duct has a second air inlet and a second air outlet, the second air inlet is communicated with the air outlet of the first fan 41, and the second air outlet is communicated with the air outlet 16.

As can be seen from the above, the hot air in the first accommodating space is sucked into the first fan 41 by the first fan 41. Meanwhile, the air outlet of the first fan 41 is communicated with the second air inlet of the second air duct, so that the hot air can enter the second air duct and is finally discharged from the air outlet 16.

It should be noted that the air outlet of the first fan 41 may be directly communicated with the air outlet 16. However, in consideration of the actual product, the installation position of the first fan 41 and the position of the air outlet 16 are not convenient in direct communication. Therefore, by providing the second air duct assembly 43, the first fan 41 and the air outlet 16 can be located at different positions, and then the air outlet of the first fan 41 is communicated with the air outlet 16 by means of the second air duct assembly 43, so as to discharge the hot air.

In some embodiments, the second air duct further includes a third air inlet, the air outlet of the second fan 51 is communicated with the third air inlet, and the air inlet of the second fan 51 is communicated with the second accommodating space. Meanwhile, the air inlet includes a second air inlet 152, and the second air inlet 152 communicates with the second receiving space.

Since the air inlet of the second fan 51 communicates with the second accommodating space, the second air inlet 152 also communicates with the second accommodating space. The external cold air enters the second accommodating space through the second air inlet 152, then exchanges heat with the second electrical element 32 in the second accommodating space, and the hot air after heat exchange is sucked by the second fan 51, finally flows through the second air duct, and is discharged from the air outlet 16.

The oven that this application embodiment provided is through the third air inlet intercommunication with the air outlet of second fan 51 and second wind channel for two fans share the second wind channel, need not to set up in addition solitary wind channel subassembly and come to be connected with second fan 51, save space.

In some embodiments, as shown in FIG. 2, the second duct assembly 43 may include a first cover 431 and a second cover 432, the first cover 431 and the second cover 432 being connected to each other and secured to the heat shield 6 to define a second duct together with the heat shield 6. The first cover plate 431 is provided with a second air inlet and a third air inlet, which are respectively communicated with the air outlet of the first fan 41 and the air outlet of the second fan 51.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
