Description

Technical Field

[0001] The utility model relates to the technical field related to cooking equipment, in particular to a stove and a split stove steaming and baking equipment. Background Art

[0002] At the same time, cooking equipment with stove steaming and baking functions has a relatively high space utilization rate in the height direction while ensuring product functions, and is more space-saving; in order to improve the space utilization rate in the height direction, most of the existing split stove steaming and baking equipment adopts a top-mounted heat source design, and the heat source is located inside the stove chassis.

[0003] The problem with this configuration is that the temperature inside the stove chassis will be higher, so a cooling system needs to be designed to cool the inside of the stove;

[0004] Most of the current cooling systems provide overall ventilation and heat dissipation for the heat source location inside the stove. However, setting up a cooling system requires designing air ducts and adding fans, and it will also occupy the internal space of the stove chassis, while its effect is only overall ventilation and heat dissipation. Therefore, adding a cooling system just to solve the heat dissipation problem requires high costs, relatively poor functionality, and relatively low cost-effectiveness. Utility Model Content

[0005] Based on this, it is necessary to provide a stove and split stove steaming and baking equipment with a more functional and cost-effective internal cooling system to address the relatively low cost-effectiveness of adding a cooling system only to solve the heat dissipation problem.

[0006] The present application first provides a cooker, including a panel, a chassis, an air duct housing, and a knob;

[0007] The chassis is fixed to the lower surface of the panel to form a containing space therebetween, the air duct housing is located in the containing space, and the air duct housing is attached to the lower surface of the panel to form a duct therebetween, a first air inlet connected to the air duct is opened on the panel, and the knob passes through the air duct housing and the first air inlet from the containing space to partially protrude from the panel to form an air intake gap between the knob and the first air inlet;

[0008] A fan is arranged in the air duct, an air outlet and a second air inlet are provided through the air duct shell, the air outlet corresponds to the outlet of the fan, and a chassis hole is provided through the chassis.

[0009] In one embodiment, the air duct housing is provided with at least one of the second air inlet ports, which are located on the side and / or bottom of the air duct housing; the chassis is provided with at least one of the chassis holes, which are located on the side and / or bottom of the chassis.

[0010] In one embodiment, the air duct housing is provided with a plurality of groups of the second air inlets, and each group of the second air inlets includes a plurality of circular holes which are provided on the air duct housing at equal intervals in a direction parallel to the panel;

[0011] The chassis is provided with a plurality of groups of chassis holes, and each group of chassis holes includes a plurality of circular holes which are provided on the chassis at equal intervals in a direction parallel to the panel.

[0012] In one of the embodiments, an igniter is further disposed in the accommodating space, the second air inlet is located on a side of the air duct housing close to the igniter, and the igniter is located between the second air inlet and the chassis hole.

[0013] In one of the embodiments, the igniter is arranged at an angle formed by two side surfaces of the chassis, and chassis holes corresponding to the igniter are opened on both side surfaces.

[0014] In one of the embodiments, a second air inlet is provided on a side of the air duct housing close to the igniter and on a bottom surface of the air duct housing close to the igniter.

[0015] In one embodiment, the air duct housing includes a first step portion and a second step portion recessed downward relative to the first step portion, the knob passes through the first step portion, the fan is arranged in the second step portion, and at least one air outlet gap connected to the accommodating space is opened through the side surface of the second step portion, the air outlet is opened on the side surface of the second step portion, and the air outlet area is smaller than the outlet of the fan.

[0016] In one of the embodiments, the first step portion is provided with a fan cover plate closing the second step portion, and the fan cover plate is provided with a through hole corresponding to the fan inlet.

[0017] In one of the embodiments, the stove further includes a display screen, which is fixed to the bottom surface of the panel and directly faces the fan.

[0018] A second aspect of the present application provides a split-type stove steaming and baking device, including the above-mentioned stove.

[0019] In the above stove, the opening through which the knob passes on the panel is used as the first air inlet. Since the knob is far away from the high temperature area, the air entering the air duct through the first air inlet is low temperature air, and the flow of low temperature air can cool the knob. The flowing low temperature air can also form a low temperature air layer, thereby playing a heat insulation role for the knob, further reducing the possibility of heat accumulation in the knob.

[0020] In addition, another part of the outside air enters the accommodation space through the bottom plate hole, and the low-temperature air flows through the components in the accommodation space (such as the igniter 80, the power board, etc.) to cool them by heat exchange, and is sucked into the air duct through the second air inlet under the action of negative pressure, thereby achieving targeted heat dissipation of some components in the accommodation space;

[0021] Finally, the fan discharges the sucked low-temperature air into the accommodating space, cooling the high-temperature area inside the stove as a whole.

[0022] To sum up, the cooling system in the stove of the present application can not only dissipate the heat inside the stove as a whole, but also achieve heat dissipation and heat insulation for the knob and targeted heat dissipation for individual parts in the accommodating space, thereby increasing the functionality of the fan and effectively improving the cost-effectiveness of the cooling and heat dissipation system.

[0034] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a stove, including a panel 10, a bottom plate 20, an air duct housing 30 and a knob 40;

[0035] The chassis 20 is fixed to the lower surface of the panel 10 to form an accommodation space therebetween, the air duct housing 30 is located in the accommodation space, and the air duct housing 30 is attached to the lower surface of the panel 10 to form an air duct therebetween, a first air inlet 11 connected to the air duct is provided on the panel 10, and the knob 40 passes through the air duct housing 30 and the first air inlet 11 from the accommodation space to partially protrude from the panel 10 to form an air intake gap between the knob 40 and the first air inlet 11;

[0036] A fan 50 is arranged in the air duct, an air outlet 31 and a second air inlet 34 are formed through the air duct housing 30 , the air outlet 31 corresponds to the outlet of the fan 50 , and a chassis hole 21 is formed through the chassis 20 .

[0037] Specifically, the air duct housing 30 is sealed and fitted with the panel 10 to form an air duct. When the fan 50 is running, negative pressure is generated inside the air duct, which has a suction force on the air around the air duct. A part of the outside air enters the air duct through the first air inlet 11 and is sucked into the fan 50, and another part of the outside air enters the accommodating space through the chassis hole 21 and is sucked into the air duct through the second air inlet 34 under the action of negative pressure.

[0038] In the present application, the opening through which the knob 40 passes on the panel 10 is used as the first air inlet 11. Since the knob 40 is far away from the high temperature area, the air entering the air duct through the first air inlet 11 is low-temperature air, and the flow of low-temperature air can cool the knob 40; the flowing low-temperature air can also form a low-temperature air layer, thereby playing a heat insulation role for the knob 40, further reducing the possibility of heat accumulation in the knob 40;

[0039] In addition, another part of the outside air enters the accommodating space through the bottom plate hole 21, and the low-temperature air flows through the components (such as the igniter 80, the power board, etc.) in the accommodating space to cool them by heat exchange, and is sucked into the air duct through the second air inlet 34 under the action of negative pressure, thereby achieving targeted heat dissipation of some components in the accommodating space;

[0040] Finally, the fan 50 discharges the sucked low-temperature air into the accommodating space to cool down the high-temperature area inside the stove as a whole.

[0041] In summary, the cooling system in the stove of the present application can not only dissipate the heat inside the stove as a whole, but also achieve heat dissipation and heat insulation for the knob 40 and targeted heat dissipation for individual parts in the accommodating space, thereby increasing the functionality of the fan 50 and effectively improving the cost-effectiveness of the cooling and heat dissipation system.

[0042] Please refer to Figure 2 As shown, in some embodiments, the stove also includes a display screen 90, which is fixed to the bottom surface of the panel 10 and directly faces the fan 50; on the one hand, the low-temperature air entering the air duct from the first air inlet 11 can cool the display screen 90 when flowing through the display screen 90 area, and on the other hand, the low-temperature air layer can also insulate the display screen 90, further reducing the possibility of heat accumulation in the display screen 90.

[0043] Please refer to Figure 2 As shown, in some embodiments, the duct housing 30 is provided with at least one second air inlet 34, which is located on the side and / or bottom of the duct housing 30; the chassis 20 is provided with at least one chassis hole 21, which is located on the side and / or bottom of the chassis 20.

[0044] Specifically, the position of the second air inlet 34 and the chassis hole 21 can be designed according to the position of the components that actually need heat dissipation, as long as the components that need heat dissipation are located between the chassis hole 21 and the corresponding second air inlet 34, and are located on the air intake path; in addition, the area of ​​the second air inlet 34 and the chassis hole 21 can be adjusted according to the actual heat dissipation required by the corresponding parts to be cooled, and the present application does not make further limitations here.

[0045] Please refer to Figure 2 As shown, in some embodiments, a plurality of groups of second air inlets 34 are provided on the air duct housing 30, and each group of second air inlets 34 includes a plurality of circular holes provided on the air duct housing 30 at equal intervals in a direction parallel to the panel 10;

[0046] The chassis 20 is provided with a plurality of groups of chassis holes 21 , and each group of chassis holes 21 includes a plurality of circular holes that are provided on the chassis 20 at equal intervals in a direction parallel to the panel 10 .

[0047] Preferably, each group of second air inlets 34 and each group of chassis holes 21 include three circular holes.

[0048] Please refer to Figure 2As shown, in some embodiments, an igniter 80 is further disposed in the accommodating space, the second air inlet 34 is located on a side of the air duct housing 30 close to the igniter 80 , and the igniter 80 is located between the second air inlet 34 and the chassis hole 21 .

[0049] Of course, the igniter 80 may also be other components that require heat dissipation, such as a power board, etc., and this application does not make any further limitations here.

[0050] Please refer to Figure 2 As shown, in some embodiments, the igniter 80 is disposed at an angle formed by two side surfaces of the chassis 20, and chassis holes 21 corresponding to the igniter 80 are opened on both side surfaces;

[0051] A second air inlet 34 is formed on the side of the air duct housing 30 close to the igniter 80 and on the bottom of the air duct housing 30 close to the igniter 80 .

[0052] This allows the low-temperature air sucked in by the negative pressure inside the air duct to pass through the igniter 80 from multiple angles to increase the contact area between the airflow and the igniter 80, thereby improving the heat dissipation effect on the igniter 80.

[0053] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the air duct housing 30 includes a first step portion 30a and a second step portion 30b that is recessed downward relative to the first step portion 30a, the knob 40 passes through the first step portion 30a, the fan 50 is arranged in the second step portion 30b, and at least one air outlet gap 32 connected to the accommodating space is opened through the side of the second step portion 30b, the air outlet 31 is opened on the side of the second step portion 30b, and the area of ​​the air outlet 31 is smaller than the outlet of the fan 50.

[0054] When the fan 50 is running, the outlet of the fan 50 will blow air, thereby blowing out part of the low-temperature air from the air outlet gap 32; with this design, it is only necessary to match the air outlet gap 32 to the parts and structures that need heat dissipation, so as to carry out targeted heat dissipation and cooling to improve the heat dissipation effect.

[0055] Please refer to Figure 4 As shown, in some embodiments, the first step portion 30 a is provided with a fan cover plate 33 closing the second step portion 30 b , and the fan cover plate 33 is provided with a through hole 331 corresponding to the inlet of the fan 50 .

[0056] Since the area of ​​the air outlet 31 on the air duct housing 30 is smaller than the outlet of the fan 50, and the fan cover 33 closes the second step portion 30b, positive pressure is generated around the fan 50 (i.e., inside the second step portion 30b), thereby increasing the blowing effect and allowing more low-temperature air to be discharged from the air outlet gap 32.

[0057] Please refer to Figure 4 As shown, in some embodiments, an igniter 80 is further provided in the accommodating space, and at least two air outlet slits 32 are opened through the side of the second step portion 30b, one of which faces the igniter 80, and the area of ​​the air outlet slit 32 is larger than that of the other air outlet slits 32.

[0058] The amount of low-temperature air discharged from the air outlet gap 32 on one side of the igniter 80 is increased to ensure sufficient cooling of the igniter 80 .

[0059] Of course, in some other embodiments, the air outlet gap 32 can also be designed according to the cooling capacity required by the heat dissipation and cooling equipment and its distance relative to the air duct. As long as the amount of low-temperature air discharged from the corresponding air outlet gap 32 can meet the heat dissipation and cooling requirements of the corresponding equipment, the present application will not make further limitations here.

[0060] The present application also provides a split-type stove steaming and baking device, including the above-mentioned stove.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
