Description

Cooking device with active purification function

Technical Field

The invention relates to the technical field of kitchen electrical equipment, in particular to cooking equipment with an active purification function.

Background

With the overall development of technologies related to the field of household appliances, household appliances are developed on two aspects of enrichment and refinement. As one of home appliances, electric cooking appliances are mainly cooking appliances for preserving, processing, and the like food materials, and with the development of enrichment and refinement, for example, in addition to a conventional gas range, a refrigerator, a microwave oven, and the like, specific forms corresponding to various cooking modes such as steaming, baking, frying, air-frying, and the like are also emerging.

Taking the hot air oven as an example, the working principle of the hot air oven is to use the circulating hot air flow to cook food materials. Specifically, along with the circulating flow of hot air flow in the liner where the food to be cooked is located, when the hot air flow flows through the food to be cooked, heat carried in the hot air flow can be transferred to the surface of the food to be cooked, and the food to be cooked can be processed in a hot air baking cooking mode by correspondingly controlling parameters such as the flow rate and the temperature of the hot air flow.

Since the food material to be cooked usually contains grease or has an additive such as grease added thereto before cooking. Thus, the hot air flow often has a cleanliness problem during cooking of the food material to be cooked. In order to deal with the problem, a product form is provided in which a purification module in the form of honeycomb ceramics is added to a hot air oven, however, at present, the purification module is usually accompanied with purification after being fixed to a certain position (for example, a position close to a fan), the purification effect mainly depends on the purification capacity of the purification module itself and the installation position thereof, and a considerable space for improving the purification capacity still exists.

Accordingly, there is a need in the art for a new solution to the above-mentioned problems.

Illustratively, one or more first fans are arranged along the circumference of the purifying part, or the first fan is arranged on the side of the purifying part far away from the cooking chamber. The purifying part can be connected with the first fan, and can also be fixed to other parts such as the cooking main body, and the purifying part and the cooking main body are both fixedly arranged on the cooking main body, for example, a person skilled in the art can determine a specific fixed connection mode according to actual requirements, for example, the purifying part is clamped at the top or the side of the cooking main body in an embedded mode, and the first fan is fixed to the cooking main body in a threaded mode.

For the above cooking device with an active purification function, in a possible implementation manner, the cooking device includes a second fan, the second fan is configured to dissipate heat of an element in the cooking device, wherein the second fan is configured with a heat dissipation air duct, a mounting area is reserved in a position of the cooking device corresponding to the heat dissipation air duct, and the first fan is detachably disposed in the mounting area.

With this configuration, a specific configuration of the cooking apparatus is given.

If in a normal situation, the second fan is a cross-flow fan arranged on the top of the cooking body, and under the action of the cross-flow fan, heat dissipation can be performed on electrical elements and the like in the cooking device. In the present invention, the first fan supporting the purification function exclusively in addition to the second fan is disposed in the purification unit, and the purification effect of the active cooking medium aimed by the present invention can be ensured in advance without intersecting with the original smoke exhausting function. On the premise of realizing the basic function, an optional installation environment is provided for the first fan specially arranged for purification.

With regard to the cooking device with active cleaning function, in a possible embodiment, the first fan comprises a fan housing, and in an assembled state, the fan housing is exposed outside the heat dissipation air duct and is detachably disposed on a wall forming the heat dissipation air duct.

With this configuration, a specific configuration of the first fan is given.

With this configuration, a specific configuration of the guide portion is given.

On the premise of realizing the corresponding guiding function, a person skilled in the art can determine the number, the connection mode between the second guiding part and the purifying part, the corresponding guiding mode, the guiding path corresponding to the guiding mode and the like according to actual requirements. For example, the second guide portion may be adapted to direct the decontaminated cooking medium away from the decontamination portion in a manner similar to or different from the first guide portion described above. For example, the second guide portion makes the cooking medium detour to the purifying portion again after being separated from the purifying portion to purify it again, and the like.

With regard to the above-described cooking apparatus with active purging function, in one possible embodiment, the downstream side of the second guide portion comprises at least one discharge opening capable of discharging the cooking medium to a target position corresponding thereto, as viewed in the flow direction after the cooking medium is purged by the purge portion.

With such a construction, a form of construction is given by the second guide portion.

It will be appreciated that the number of dispensing ports, the dispensing path, the specific definition of the target location to be dispensed and the location of the target location relative to the cooking chamber, etc., may be determined by one skilled in the art based on actual requirements. For example, the target location may be external, central, or internal to the cooking device, and the cooking medium at the target location may be used directly, after reheating, or no longer for the cooking medium. Illustratively, the cooking device is an oven, and the target location may be a location near the heating tube (which may be considered a middle portion of the cooking device, an outer portion of the cooking chamber) such that the portion of the cooking medium may be reheated and reused as a cooking medium. Such as the dispensing opening of the second guide portion, is typically a pipe away from the nozzle of the purification section or an additional structure (e.g., a nozzle) at the nozzle, etc.

Taking the dispensing opening as a nozzle, for example, the dispensing opening can be movably (e.g., rotatably) disposed on the cooking body, so as to: by means of which the form of the cooking medium is dispensed again into the cooking chamber. Taking rotation as an example, a person skilled in the art can determine the specific structure depending on which rotation is realized, the allowable rotation range, and the like according to actual requirements.

With regard to the above-mentioned cooking appliance with active purging function, in one possible embodiment, the target positions include a first target position and/or a second target position, wherein the purged cooking medium can be discharged to the external environment of the cooking appliance in case the cooking medium is dispensed to the first target position; wherein the cooking medium after the purification treatment can be dispensed to the cooking chamber again in a state that the cooking medium is dispensed to the second target position.

With this configuration, the cleanliness of the cooking medium can be ensured even when the cooking medium is discharged to different target positions.

In particular, in case the cooking medium is discharged to the first target location, the air quality to the external environment such as the kitchen where the cooking apparatus is located is reduced, thus improving the user experience. In case of discharging the cooking medium to the second target position, it is possible to make the cooking medium have a quality with good cleanliness when cooking the material to be cooked again, thus optimizing the use performance of the cooking apparatus.

It is understood that the timing and duration of the dispensing of the cooking medium to the first target position and the second target position, and parameters such as the flow rate during the dispensing process can be determined by those skilled in the art according to actual needs.

It is understood that a person skilled in the art may determine the specific position of the first/second target positions relative to the cooking device, the number of the first/second target positions, the relative position between the first/second target positions, the specific path for the cooking medium to reach the first/second target positions, etc. according to actual requirements. For example, the cooking apparatus has A, B, C three positions at the position corresponding to the cooking chamber, and the second target position includes three positions.

Taking the target positions including the first target position and the second target position as an example, it can be understood that a person skilled in the art can determine the specific structure for switching the cooking medium between the two dispensing paths according to actual requirements, for example, the two dispensing paths are independent from each other and thus can be switched without interference, or a switching part is used to switch the communication state of the two dispensing paths. If the first target position includes a and the second target position includes B, C two positions, the second guide portion includes three paths corresponding to the three positions, each path is provided with a valve for adjusting the path, such as communication, non-communication, partial communication, etc., and the three valves constitute a switching portion.

With this configuration, a specific arrangement of the dispensing opening on the cooking body is given.

It can be seen that in this case, the heat in the fan guard assembly can be used to preheat the cooking medium that is again dispensed into the cooking chamber to some extent, thereby ensuring the temperature quality of this portion of the cooking medium.

With the above-described cooking apparatus with active purging function, in one possible embodiment, the second guide portion comprises a duct.

With this configuration, a specific configuration of the second guide portion is given.

It should be noted that, the connection relationship between the air inlet of the first fan (the component of the first guiding portion) and the purifying portion, between the upstream side of the duct and the air outlet of the first fan, and between the downstream side of the duct (the emission opening) and the structure corresponding to the target position forms the flow path of the cooking medium, for example, the connection manner may include a physical connection/abutment, or may not include a physical connection/abutment (such as alignment). Illustratively, the two do not produce a direct physical connection but rather each have a connection with an intermediate component.

In a possible embodiment, the purge portion is provided to the cooking body and, in an assembled state, at least a part of the purge portion is exposable to the cooking chamber.

With this configuration, a specific arrangement of the purifying part in the cooking apparatus is given.

It will be appreciated that the manner in which it is disposed on the cooking body and its extent and manner of exposure to the cooking chamber may be determined by those skilled in the art according to actual needs. For example, the purification part is movably (e.g. telescopically) arranged on the cooking main body, and when the active purification function of the purification part needs to be started, the purification part extends into the cooking chamber, otherwise, the purification part retracts to a state with a small exposure range or no exposure. More specifically, for example, in the case where the cooking main body has an installation space provided with a closing plate, the purifying part can be completely unexposed by retracting the purifying part into the installation space and closing the installation space by the closing plate or the like.

As shown in fig. 1 to 6, the oven 100 mainly includes a cooking body 1, a fan guard assembly 2, and a purge portion. Wherein, the cooking main body 1 is formed with a cooking chamber (e.g., a liner) for containing food to be cooked. If a shelf is arranged in the inner container, the food to be cooked is directly placed on the shelf or placed in a vessel (such as a plate) placed on the shelf. The fan cover component 2 is mainly used for forming circularly flowing hot air flow in the inner container, and cooking food materials to be cooked by taking the hot air flow as a cooking medium. The purifying part is mainly used for purifying hot air flow as a cooking medium at any time (such as middle and later cooking) during cooking of food to be cooked.

In one possible embodiment, the inner container is provided with a door body which can be opened (such as being opened in a vertical pivoting manner or opened in a transverse pivoting manner) at a side close to the operation side of the user (such as the side facing the user, which can be generally referred to as a front side). The liner is provided with a back plate at the side far away from the user (such as the side which can be called as the back side), wherein the back plate comprises a first back plate 11 and a second back plate 12 which are arranged in sequence from front to back, and the inner side of the top of the liner is provided with a heating pipe 13 so as to supplement and heat the hot air flow circulating in the liner. The purifying part is also arranged at the inner side of the top of the inner container.

In a possible embodiment, the fan guard assembly 2 mainly comprises a fan guard 21, a centrifugal fan a and a heating coil 23, a hot air chamber is formed between the front side of the first back plate 11 and the fan guard 21, the fan guard has a return air inlet 211 near the middle thereof, and a supply air outlet 212 is arranged around the circumference of the return air inlet. A centrifugal fan a is arranged in the hot air chamber at a position corresponding to the air return opening, the centrifugal fan a comprises a motor (not shown) and a fan 222, the fan is located in the hot air chamber (the front side of the first back plate), the motor is located at a position corresponding to the hot air chamber (the rear side of the first back plate) of the first back plate, the motor is fixed on the first back plate through a motor support 2211, the motor support is simultaneously fixed on the second back plate 12, and the motor is accommodated in an installation space between the first back plate and the second back plate in an assembled state. The motor rotates to drive the fan to rotate at a position facing the air return opening, and the rotation of the fan can lead the air in the inner container to flow through the air return opening and then to be led into the hot air chamber. A heating coil 23 is also provided in the hot blast chamber at a position corresponding to the return air opening, e.g. a fan is provided in the area encircled by the heating coil. Therefore, under the action of the fan, air in the inner container flows through the air return opening and is sucked into the hot air chamber, the air is heated by the heating coil pipe and is converted into hot air carrying heat, and then the hot air is thrown to the air supply opening on the periphery and is sent into the inner container again. By such circulation, the hot air flow can continuously distribute the air carrying heat to the surface of the food material to be cooked, thereby realizing the main cooking function.

In the present embodiment, the air return opening 211 is a substantially disk-shaped area formed by grid holes, and the air supply opening 212 is a plurality of air supply points surrounding the outside of the disk-shaped area, for example, the plurality of air supply points are substantially arranged around the outside of the disk-shaped area and form a ring-shaped area. Obviously, the specific configuration form of such a return air inlet and an air supply outlet is only a specific example, and those skilled in the art can flexibly adjust the configuration form according to actual needs, and for example, the air supply outlet may include a plurality of annular regions surrounding the return air inlet and having different radial dimensions, or a plurality of strip-shaped holes arranged at intervals are added at positions of the fan cover outside the annular regions, and the like.

In a possible embodiment, the purification part mainly comprises a purification part 31 mounted to the inside of the top of the liner, a centrifugal fan b32 (first fan) constituting a first guide part, and a duct 33 constituting a second guide part, wherein the purification part is capable of purifying the hot air flow as it approaches and flows through the purification part. The centrifugal fan b is arranged above the purification part, and can actively guide hot air flow to be close to the purification part under the suction action of the centrifugal fan b so as to purify the hot air flow. The upstream side of the duct 33 is connected to the outlet of the centrifugal fan b so as to guide the hot air flow after the treatment of the purification section to a position away from the purification section.

In the present invention, the downstream side of the duct has a discharge port, and accordingly, a communication port 24 is provided in both the fan guard 21 and the first back plate 11 constituting the fan guard assembly. The hot air thus purified flows through the duct 33 to the downstream discharge port, and then the hot air is discharged again to the inner container to perform the cooking function of the food to be cooked again. In this embodiment, the communication port is located at a position near the bottom of the fan guard assembly, and the duct 33 is vertically disposed and tightly attached to the wall of the first back plate near the outer side, so that the heat dissipated by the heating coil included in the fan guard assembly can be effectively utilized to preheat the hot air flowing through the duct and then be distributed to the inner container. The back of inner bag in addition is provided with heat preservation parts such as heat preservation cotton usually, so such setting can reduce effectively because the setting of purifying part causes the oven in the heat loss of culinary art in-process, has consequently reduced because the setting of purifying part is to the influence of the inside temperature field of oven, has guaranteed the culinary art effect of oven.

Obviously, the number, the arrangement position, the arrangement mode of the above-mentioned emitting openings and the corresponding emitting mode of the hot air flow are only an exemplary description, and those skilled in the art can flexibly modify them according to the actual situation, such as but not limited to:

1) the number of the opening openings is increased, for example, communication openings corresponding to the distribution openings are respectively arranged on the left side and the right side of the fan cover component, or the communication openings corresponding to the distribution openings are also arranged on the top, the (left, right) side part, the bottom and other positions of the inner container. Illustratively, one or more communication ports are provided at the intersection between the (left, right) side portion and the bottom portion;

2) the downstream side of the pipeline is additionally provided with a structure with a dispensing opening function, such as a nozzle, and the nozzle is movably arranged at the position of the cooking main body corresponding to the communication opening. For example, the nozzle can adjust the distribution direction of the purified hot air flow when the hot air flow is distributed to the inner container again through the rotation of the nozzle relative to the communication port;

3) in addition to delivering the hot gas flow to the inner container, the hot gas flow can be directly exhausted out of the external environment of the oven, or returned to a position close to the purifying part for secondary purification and then exhausted. In case of exhausting the hot air flow into the external environment, as compared to the case of non-cleaning treatment, the air quality of the kitchen environment where the oven is located can be improved, and thus the user experience can be improved.

In a possible embodiment, a cross-flow fan 4 is arranged between the sandwich layers of the top inner side and the top outer side (top cover) of the inner container, and is used as a second fan, and the main function of the cross-flow fan is heat dissipation. Specifically, the cross-flow fan is provided with a plate-shaped heat dissipation air duct 41 adapted to the axial air intake area of the cross-flow fan. The centrifugal fan b32 in the purification part is arranged in the middle of the heat dissipation air duct. Specifically, a mounting area that is not communicated with the heat dissipation air duct is provided in an area covered by the heat dissipation air duct, the centrifugal fan b is mounted to the mounting area, an air inlet of a fan housing (volute) 321 of the centrifugal fan b is aligned with the purification portion 31, and an air outlet of the volute is butted with (an upstream side of) the duct 33. In this embodiment, the volute is disposed on the wall of the heat dissipation air duct in a multi-point fixing manner through three fasteners 322. Based on this, for the above case 3), the hot air flow after the purification treatment can be directly exhausted out of the external environment of the oven. As an exemplary implementation may be: the downstream side of the duct 33 may further have a dispensing opening, which can be connected to the heat dissipation air duct, specifically, another communication opening is reserved on the heat dissipation air duct, and the purified hot air flow can be discharged out of the external environment through the heat dissipation air duct by butting the first dispensing opening with the communication opening (such as direct butting or butting through an intermediate component). Since the downstream side of the heat dissipation air duct is itself open to the outside environment, it is not necessary to add a structure such as an exhaust port on the downstream side of the heat dissipation air duct, which corresponds to the discharge of the hot air flow.

In one possible embodiment, the purification section 31 includes a housing, a catalyst module 312 accommodated in the housing, and a heating member 313 specially provided for the catalyst module 312. Illustratively, the housing includes an upper cover 3111 and a lower mesh-like structure (e.g., an oil-blocking screen) 3112, e.g., the cover is fixed to the top of the inner container by way of flange connection, and in the installed state, the mesh-like structure is exposed to the cooking chamber through a reserved opening 14 of the top so as to achieve the introduction of the hot air flow, and the heating element is fixed to the oven by a support 3131.

In this way, under the action of the centrifugal fan b, the hot air flow in the cooking chamber can be guided to the area close to the mesh-shaped structure, then enters the inside of the shell through the mesh-shaped structure, and is purified in a chemical decomposition mode when approaching and flowing through the catalytic module accommodated in the purification space.

Such as catalytic module 312, is typically constructed by attaching a catalyst to the carrier that promotes the decomposition of substances such as grease in the hot gas stream. Illustratively, the support is a porous metal framework and the catalyst is affixed to the support in the form of a coating. Illustratively, the active heating portion of the heating member 313 is housed inside the housing and below the catalytic module.

In one possible embodiment, the purge section 31 is aligned with the centrifugal fan b32 in the following manner: the top of the housing body is extended with a first pipe section 31111 along its axial direction, a second pipe section 323 is arranged at a position of the centrifugal fan b corresponding to its air inlet, for example, the second pipe section is fixed to the centrifugal fan b in a flange connection manner, the first pipe section and the second pipe section can form a passage for hot air flow from the purification part to the centrifugal fan b by being not connected but aligned, and can also be aligned in a connection manner to form a passage for hot air flow from the purification part to the centrifugal fan b, for example, aligned on the basis of partial plug-in or screw connection, so as to form a passage for hot air flow from the purification part to the centrifugal fan b.

It will be understood that the above-mentioned structural form of the purge portion and the form of the constraint of the hot air flow from the purge portion to the centrifugal fan b are only exemplary descriptions, and those skilled in the art can flexibly adjust them according to the actual situation, such as changing two pipe segments into one pipe segment which is only integrally formed with the housing but not fixed to the centrifugal fan b.

It can be seen that in the oven of the present invention, the arrangement of the purifying portion can effectively purify the hot air flow as the cooking medium in the oven.
