Referring to fig. 1 to 10, a cooking appliance 100 according to an embodiment of the present invention includes a case 300 for cooking food, a bottom plate 120, and a rack 110, wherein a cavity for placing the food is provided in the case 300, and wherein, referring to fig. 2 and 3, the rack 110 covers a bottom surface of the bottom plate 120 to form a mounting cavity between the rack 110 and the bottom plate 120.

Wherein, it can be understood that its installation cavity is used for installing electrical component 200, specifically, electrical component 200 is installed in chassis 120, and all electrical components 200 are covered in the installation cavity by support 110, when water in the cavity permeates into chassis 120 from the weld, it firstly drops onto support 110 and flows onto chassis 120 along support 110 instead of directly dropping onto electrical components 200, and water from the cavity is prevented from directly dropping onto electrical components 200, thus ensuring that electrical components 200 operate normally.

It should be mentioned that during cooking, water is generated when the food is heated, and the water is left in the cavity and flows away from the weld in the cavity, so that a small amount of water flows into the bottom plate 120.

It should be noted that in some embodiments, when the bracket 110 is covered on the chassis 120, a mounting cavity isolated from the external space is formed in the chassis 120, specifically, the bracket 110 isolates the electrical component 200 in the mounting cavity, and after water drops from the cavity fall onto the bracket 110, a part of the water remains on the bracket 110, and a part of the water flows into the chassis 120 without dropping onto the electrical component 200. In other embodiments, the bracket 110 covers the electrical component 200, but does not completely isolate the installation cavity from the external space, and the bracket 110 ensures that water from the cavity does not drip into the electrical component 200 from above, and that water seeping into the cooking utensil 100 from the weld does not affect the normal operation of the electrical component 200.

It will be appreciated that, with reference to fig. 5 and 6, the bracket 110 includes a baffle 111 and a sidewall 112, the baffle 111 overlying the mounting plate 130; the side walls 112 are disposed at the sides of the barrier 111 and are connected to the bottom surface of the bottom chassis 120. The baffle 111 is used for shielding water seeped from the cavity and preventing the water from directly dripping onto the electric element 200, and the side wall 112 is used for guiding the water to the bottom plate 120, wherein in the existing cooking appliance, the bottom plate 120 of the existing cooking appliance is designed with a structure for draining water, the side wall 112 guides the water to the bottom plate 120 and discharges the water out of the cooking appliance through the structure for draining water, so that the water is prevented from directly flowing into the electric element 200, and the normal operation of the electric element 200 is further ensured.

It should be mentioned that, in practical use, the water in the cavity seeps out from the weld, the seeped water firstly drops onto the baffle 111, the seeped water dropping onto the baffle 111 flows along the baffle 111 in all directions, and a part of the water flows along the side wall 112 to the bottom plate 120.

Specifically, when water in the cavity spreads to the weld, the water seeps from the weld in the cavity, drips toward the bottom plate 120, firstly drips onto the baffle 111, is blocked by the baffle 111, and is prevented from directly dripping into the electrical component 200, the water dripped onto the baffle 111 slides on the baffle 111 and flows to the edge of the baffle 111, wherein part of the water flows to the edge provided with the side wall 112, flows to the bottom surface of the bottom plate 120 along the side wall 112, and is finally discharged out of the cooking utensil.

It should be noted that, referring to fig. 5 and 6, the sidewalls 112 are disposed at two opposite edges of the baffle 111 to form two opposite sidewalls 112 on the baffle 111. The water flows on the baffle 111 and flows to the edge of the baffle 111, and because the water has the adhesion, the water flowing to the edge provided with the side wall 112 flows to the bottom plate 120 along the side wall 112, and the water flowing to the two sides not provided with the side wall 112 directly drops to the bottom surface of the bottom plate 120 instead of the electrical component 200, thereby ensuring the normal operation of the electrical component 200.

It should be noted that in the above embodiment, the baffle 111 is required to completely cover the area of the chassis 120 where the electrical component 200 is installed, so as to completely block water from the cavity.

It will be appreciated that in other embodiments, the side walls 112 are provided in plurality, so that the plurality of side walls 112 enclose the installation cavity into a space isolated from the external space (not shown in the drawings), thereby achieving a better waterproof effect.

It is understood that, referring to fig. 4, the drainage structure provided on the base plate 120 may be a hole for drainage, and specifically, the side wall 112 of the base plate 120 is provided with the first drainage port 121. When water flows into the base plate 120, the water in the base plate 120 rises and finally flows out of the cooking appliance at the first water discharge port 121, so that the water is prevented from accumulating in the base plate 120, and the electric element 200 is prevented from being damaged due to the fact that the water soaks the electric element 200.

In addition, it can be understood that, referring to fig. 9, a bottom of the bottom plate 120 is generally connected with a foot for supporting, therefore, a plurality of screw holes 123 for inserting screws are provided on the bottom surface of the bottom plate 120, and the screw holes 123 can also be used as a structure for draining the bottom plate 120, so that water flowing into the bottom plate 120 can be drained from the screw holes 123.

It is understood that, referring to fig. 2, the bracket 110 is further provided with an air inlet end 113 and an air outlet end 114, and the air inlet end 113 is provided with a fan assembly 140. The fan assembly 140 is used for drawing in cold air, the air inlet end 113 and the air outlet end 114 are arranged in a penetrating manner, and the cold air drawn by the fan passes through the installation cavity to cool the electric element 200 in the installation cavity. It should be mentioned that, during the operation of the cooking appliance, a large amount of heat is generated in the cavity, and the heat in the cavity is transferred to the space inside the chassis 120, so that the electric element 200 is easily heated, and the electric element 200 is further damaged, which affects the normal operation of the cooking appliance. The fan assembly 140 introduces cold air to cool the electrical element 200, so that the electrical element 200 can work at a low temperature, and the normal operation of the electrical element is ensured.

In addition, it can be understood that the cooling air is introduced and flows along the direction a, so as to cool the electrical component 200, protect the electrical component 200, prevent the electrical component 200 from being damaged due to too high heat, prolong the service life of the electrical component 200, and reduce the maintenance times and cost.

Since the heat in the cavity is transferred to the space inside the base pan 120, the cool air blown in from the air inlet end 113 is easily heated before being blown in, so that the cool air blown into the installation cavity becomes hot air, which does not cool the electric components 200, and it is possible to accelerate the loss speed of the electric components 200, and for this reason, it can be understood that, referring to fig. 2 and 7, the cooking appliance 100 further includes the heat insulation plate 150 disposed above the air inlet end 113. The heat insulation plate 150 separates the space above and below the air inlet end 113, and when the heat of the cavity is transferred to the space in the chassis 120, the air above the heat insulation plate 150 is heated first, and the air above and below is blocked by the heat insulation plate 150, so that the blown cold air is prevented from absorbing excessive heat, the air blown into the installation cavity is ensured to cool the electric element 200, and the electric element 200 is prevented from being overheated to cause failure or damage.

Wherein, this heat insulating board 150 can incline or horizontal setting in the top of air inlet end 113, and the tip edge of heat insulating board 150 and baffle 111 contact, and when leading-in cold wind in air inlet end 113 department, this heat insulating board 150 can avoid the heat to transmit to in the cold wind of leading-in through fan subassembly 140, wherein, refer to fig. 7, when heat insulating board 150 inclines to set up, still can lead to the cold wind that fan subassembly 140 introduced, makes cold wind blow into to the installation cavity from air inlet end 113.

It can be understood that, by injecting cold air into the mounting cavity through the fan assembly 140, the electric element 200 which is working can be effectively cooled, so that the electric element 200 can keep a normal working state, the problem of temperature rise of the electric element 200 in the chassis 120 is solved, and the reliability of the use of the whole cooking appliance is improved.

In addition, the electric element 200 does not include the fan assembly 140, the electric element 200 includes components and circuits used by the cooking appliance for cooking food, and the fan assembly 140 serves the electric element 200, so that the electric element 200 can work at a proper temperature, and the working effect of the cooking appliance is ensured.

It should be mentioned that a vertically arranged partition 151 is disposed on the chassis 120, the partition 151 is disposed at the air inlet end 113 of the bracket 110, the upper end is used for connecting and fixing the heat insulation board 150, the electric element 200 and the fan assembly 140 are respectively disposed at two sides of the partition 151, and a vent 152 is opened in the partition 151 for blowing cold air into the installation cavity and cooling the electric element 200.

It is understood that, referring to fig. 3, in order to avoid direct contact of the electric components 200 with water in the base pan 120, the cooking appliance 100 further includes a mounting plate 130, and the mounting plate 130 is disposed between the bracket 110 and the base pan 120. Specifically, the electrical components are arranged on the mounting plate 130 to be mounted in the chassis 120, the electrical components 200 arranged in the chassis 120 are not in direct contact with the bottom surface of the chassis 120, and a small amount of water seeping from the bottom surface of the chassis 120 is not in direct contact with the electrical components 200, so that the situation that water which is not drained in time directly flows into the electrical components 200 to cause damage or malfunction of the electrical components 200 is avoided, and the cooking utensil can work normally is ensured.

Specifically, when the cooking appliance is cleaned, a large amount of water is required to wash, and therefore, the amount of water seeping out of the weld in the cavity is large, resulting in an increase in water flowing onto the bottom plate 120 for a short time, easily resulting in water accumulating in the bottom plate 120 and soaking the electrical component 200, and for this reason, it can be understood that, referring to fig. 2 and 8, the mounting plate 130 and the bottom surface of the bottom plate 120 are provided with the gap 131. The mounting plate 130 is fixed on the chassis 120 and keeps a certain distance with the bottom surface of the chassis 120 to form a gap 131 between the mounting plate 130 and the bottom surface of the chassis 120, and specifically, the electric element 200 is mounted on the mounting plate 130 and is mounted in the chassis 120 together with the mounting plate 130, wherein, since the electric element 200 is mounted on the mounting plate 130, the electric element 200 is spaced apart from the bottom surface of the chassis 120, when water permeates into the chassis 120 from the inner cavity, if the water amount is too large, the water is accumulated in the chassis 120, and by providing the gap 131 between the mounting plate 130 and the bottom surface of the chassis 120, the water seeped from the inner cavity is accumulated, thereby avoiding the problem of soaking the electric element 200.

In addition, the gap 131 is left at the bottom of the electrical element 200, and can also be used as a heat dissipation channel formed below the electrical element 200, when cold air is driven by the fan assembly 140, the cold air can pass through the upper side of the electrical element 200 and the lower side of the electrical element 200, and the electrical element 200 is cooled from the upper side and the lower side of the electrical element 200 respectively, so as to improve the cooling effect, it should be mentioned that the height of the gap 131 is 10mm, so as to allow sufficient cold air to blow in, ensure that the electrical element 200 cannot be soaked, and further, prevent the electrical element 200 from being soaked due to excessive water accumulation.

Through the air inlet end 113 and the air outlet end 114 which are designed in a penetrating mode, the air duct design with the functions of back and forth outlet is achieved, the electric element 200 is cooled from the upper portion and the lower portion of the electric element 200 respectively, the problem of temperature rise of an electric device can be greatly improved, and the reliable operation of the electric device is guaranteed.

It will be appreciated that in order to further avoid the problem of soaking the electrical components 200, with reference to figure 5, the first drain opening 121 is provided below the mounting plate 130. When water is excessive and accumulated on the chassis 120, accumulated water can be discharged out of the cooking appliance through the first water outlet 121, so that the water is prevented from accumulating to the position where the water overflows the mounting plate 130, the electric element 200 is prevented from being soaked by the accumulated water, and the normal use of the cooking appliance is ensured.

Referring to fig. 10, in order to more rapidly drain the water in the runner base 120, the lower edge of the first drain port 121 extends to the bottom of the base 120, so that the water flowing into the base 120 is more timely drained, and the drainage effect is improved.

After a long time use, the first drain opening 121 disposed on the bottom plate 120 is easily blocked by sundries, so that a user cannot find a problem in the first time and continuously uses the cooking appliance, at this time, water accumulated in the bottom plate 120 cannot be quickly drained, which may cause excessive accumulation of water in the bottom plate 120, and therefore, in order to improve a drainage effect, it can be understood that the side wall 112 of the bottom plate 120 is provided with the second drain opening 122, and the second drain opening 122 is located between the first drain opening 121 and the mounting plate 130. When the first drain port 121 is blocked, the rising water level can make the accumulated water flow out from the second drain port 122 above the first drain port 121, and ensure that the water in the chassis 120 does not flow to the electric element 200.

It is understood that the bottom surface of the base plate 120 is inclined downward toward the side where the first drain port 121 is located. When the water drops on the bottom plate 120, the inclined bottom surface guides the water to the first drain port 121, and more specifically, referring to fig. 2, the water flowing to the bottom plate 120 flows to the first drain port 121 and the second drain port 122 along the direction B, so that the water on the bottom plate 120 is quickly drained, and the water in the bottom plate 120 is prevented from being accumulated in the bottom plate 120.

It will be appreciated that in general use, the bottom of the base plate 120 is provided with feet (not shown), and the feet disposed near the first drain opening 121 are at a lower height than the feet disposed at the end away from the first drain opening 121, so that the bottom of the base plate 120 is inclined and serves to rapidly guide water toward the first drain opening 121, and thus the water in the base plate 120 flows out of the cooking utensil.

Wherein, support 110 is the sheet metal component material, and lateral wall 112 is for being bent by the same sheet metal component and forming, and in order to cooperate the embodiment that the bottom of chassis 120 is installed with the stove foot, refer to fig. 5, the lateral wall 112 that sets up in the edge of baffle 111 needs to divide into a plurality of solitary plate element to the chassis 120 that the cooperation slope set up. It will be appreciated that in other embodiments, referring to fig. 6, the side wall 112 may be a one-piece plate formed by bending a sheet metal member.

In another embodiment, the bottom plate 120 may be directly provided with an inclined bottom surface to guide water to the first drain port 121, so that water may be quickly guided to the first drain port 121 and the water in the bottom plate 120 may flow out of the cooking utensil.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
