Description

Food processor capable of steaming and boiling

Technical Field

The utility model belongs to the technical field of domestic cooking appliance, especially, relate to a food preparation machine that can cook.

Background

With the improvement of living standard, various household electrical cooking appliances, such as electric ovens, electric chafing dishes, frying and baking machines, are emerging continuously. Among them, the electric steamer is a new household cooker in recent years, and the electric steamer generally includes a lower casing at the bottom, a container and a heating assembly arranged in the lower casing, and an upper casing covering the top of the lower casing, wherein the heating assembly can be a steam generator for directly generating steam or a simple electric heating plate. When the food materials need to be cooked, the steam generator generates steam, so that the food materials in the container are cooked; or placing a vessel such as a bowl and a plate and water in the container, placing food materials in the vessel, and then heating the water in the container to form steam when the electric heating disc is started, so that the food materials in the vessel can be steamed and processed.

It will be appreciated that as a large amount of steam is generated, the pressure rises rapidly, and for this reason, we provide the passengers with a steam outlet in the upper housing through which steam from the cooked food material can be discharged outwardly so that the pressure of the steam is maintained at a suitable level.

However, the existing steam discharging structure has the following defects: since the steam is raised upward, one generally places the steam outlet on the top surface of the upper housing. And the cross section of the steam outlet is generally small in order to avoid a decrease in thermal efficiency and a delay in the progress of cooking due to the leakage of a large amount of steam from the beginning of cooking. Therefore, when the steam is gradually increased and the pressure is gradually increased, the steam with higher pressure can be sprayed out from the steam outlet at a high speed, and at the moment, if a user opens the upper shell by hand to observe the cooking condition of the food, the food is easily scalded by the steam sprayed out at a high speed, so that potential safety hazards are generated. Especially, when the temperature is high in summer, the sprayed steam cannot form white water mist quickly, and a user cannot detect the sprayed steam in time, so that the possibility of accidents such as scalding is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a food preparation machine that can cook can show and reduce outside exhaust steam pressure to reduce the velocity of flow of steam, and then reduce and reduce the probability that the user was scalded, promote food preparation machine's security.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a food preparation machine that can cook, includes casing, last casing, sets up the container that is used for holding edible material in the casing down, sets up the culinary art subassembly that is used for cooking edible material in the casing down, go up the steam outlet that is equipped with steam channel on the casing and communicates with the external world, steam channel one end is the basic passageway of intercommunication container, and the other end is the step-down passageway that radially expands and communicate steam outlet outward, the cross section of step-down passageway is greater than the cross section of basic passageway.

The utility model discloses a steam passage includes the basic passageway of being connected with the container and the step-down passageway that communicates with the steam outlet to the cross section of step-down passageway is greater than the cross section of basic passageway. Known by Bernoulli's law, gaseous pressure and volume are the inverse ratio, like this, when steam enters into the pressure reduction passageway from basic passageway, its volume enlarges in the twinkling of an eye, and correspondingly, its pressure then reduces rapidly, and the steam of reduced pressure is discharged slowly from the steam outlet, can avoid steam to spout from the steam outlet is high-speed effectively, and then avoids causing potential safety hazards such as scald to the user.

It can be understood that the cross section of basic passageway can be according to the corresponding cross section of emission needs design of steam, and the cross section of step-down passageway can be as far as possible than the cross section of basic passageway big to make steam fully step down, at this moment, even user's hand contacts steam, because the velocity of flow, the pressure of steam are lower, consequently, the user can move away the hand fast, makes the steam volume of hand contact in unit interval show the reduction, promotes the utility model discloses a security.

Preferably, a pressure reducing step is formed between the base passage and the pressure reducing passage, the cross-sectional area of the opening end of the base passage is S1, and the cross-sectional area of the end of the pressure reducing passage communicated with the steam outlet is S2, 1/10 ≦ S1/S2 ≦ 1/3.

Because the step-down step is formed between basic passageway and step-down passageway, consequently, when steam passes through basic passageway entering step-down passageway, its cross section and corresponding volume have an increase sudden change, and correspondingly, the atmospheric pressure of steam then has a reduction sudden change, and the steam export of casing outwards escapes from last after the step-down to be favorable to reducing the potential safety hazard that steam caused. Through the cross section proportion of rationally controlling step-down passageway and basic passageway, the velocity of flow of the atmospheric pressure of existing reduction steam to promote the security, can avoid too big step-down passageway unreasonable space that occupies the casing again, be favorable to the arrangement of other structures in class.

When S1/S2 < 1/10, the pressure reduction channel is oversized, so that the internal space of the upper shell is occupied, and the arrangement of other structures is influenced; when the pressure of S1/S2 is more than 1/3, the pressure reduction effect of the steam is reduced, thereby causing potential safety hazard.

Preferably, a water receiving groove is arranged below the opening of the base channel in the upper shell.

It can be understood that the temperature of the upper shell and the steam channel in the upper shell is lower than that of the steam, and when the high-temperature steam escapes outwards through the base channel, the pressure reducing channel and the steam outlet, the temperature of the steam is reduced, so that condensed water is easily formed in the steam channel. The utility model discloses be equipped with the water receiving tank that is located basic passageway opening below in last casing, form like this in the water receiving tank of below is instiled into to the comdenstion water accessible basic passageway opening in the steam channel to avoid the comdenstion water to drip on the edible material in the container and influence the taste.

It should be noted that, because the water receiving tank is located below the opening of the base passage, that is, a gap is formed between the opening of the base passage and the water receiving tank, steam can enter the base passage through the gap. Therefore, the arrangement of the water receiving tank does not influence the discharge of steam, the heat of the steam can heat the water receiving tank, the condensed water in the water receiving tank is heated and then evaporated, and the accumulation of the condensed water in the water receiving tank is effectively avoided.

Preferably, the upper shell is internally provided with a hot air assembly which can output hot air into a container below, and an oil shield which is positioned below the hot air assembly and allows hot air to pass through, wherein the oil shield is provided with the water receiving groove protruding downwards.

The utility model discloses set up hot-blast subassembly in class to make it when cooking, still have the efficiency of air frying pan, in order to adapt to the processing of different edible materials. Especially, set up the water receiving tank on the oil shield of hot-blast subassembly below, at this moment, bellied water receiving tank down can play the effect of similar handle to make things convenient for oil shield and water receiving tank's installation, dismantlement and washing.

Preferably, the oil shield is provided with two water receiving grooves which are centrosymmetric, and the bottom surfaces of the water receiving grooves incline upwards from inside to outside in the radial direction of the upper shell.

Two water receiving grooves which are symmetrically distributed facilitate the installation of the oil shield, and a user can ensure that one water receiving groove is arranged below the steam channel no matter the oil shield is installed in the forward direction or the reverse direction. In addition, because the bottom surface of the water receiving tank inclines upwards from inside to outside in the radial direction of the upper shell, the condensed water dropping into the water receiving tank naturally flows to one side of the water receiving tank close to the center of the upper shell. As mentioned above, the utility model discloses be equipped with hot-blast subassembly in last casing, hot-blast subassembly sets up in last casing central point and puts. Therefore, the condensed water close to the center of the upper shell is heated by the hot air assembly to form steam more quickly and is discharged outwards, and the accumulation of the condensed water in the water receiving tank is effectively avoided.

Preferably, the depressurization step slopes downward from the depressurization channel to the base channel.

It can be understood that, since the depressurization channel is close to the steam outlet communicating with the outside, the temperature of the steam in the entire steam channel is gradually decreased from the base channel to the depressurization channel. That is, more condensed water is formed in the depressurization channel. Since the pressure-decreasing step is inclined downward from the pressure-decreasing passage to the base passage, that is, a chamfer is formed between the pressure-decreasing passage and the base passage. When condensed water is formed in the pressure reduction channel, the condensed water can conveniently flow downwards into the basic channel along the inclined chamfer angle and drop into the water receiving tank, so that the condensed water is effectively prevented from accumulating on the pressure reduction step.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, a food processor capable of cooking comprises a lower casing 1 at the bottom, an upper casing 2 arranged at the upper part of the lower casing and having control keys on the surface, a container 3 (or inner pot) arranged in the lower casing for containing food materials, and a cooking assembly arranged in the lower casing for cooking food materials. Furthermore, as shown in fig. 2, the upper casing is provided with a steam passage 4 and a steam outlet 21 communicating with the outside, the steam passage has a lower end provided with a base passage 41 communicating with the vessel and an upper end provided with a depressurization passage 42 communicating with the steam outlet, and the depressurization passage is radially outwardly expanded with respect to the base passage so that the cross section of the depressurization passage is larger than that of the base passage.

When the culinary art subassembly starts to thereby when beginning to cook the edible material in the container, can produce a large amount of steam, steam enters into the pressure reduction passageway from basic passageway, and at this moment, the volume of steam enlarges in the twinkling of an eye, and correspondingly, the pressure of steam then reduces rapidly, and the steam of reduced pressure slowly discharges from steam outlet pressureless to can avoid steam to follow the high-speed blowout of steam outlet effectively, and then avoid causing potential safety hazards such as scald to the user.

It can be understood that the cross section of basic passageway can be according to the corresponding cross section of emission needs design of steam, and the cross section of step-down passageway then can be bigger than the cross section of basic passageway as far as possible to make steam fully step down, at this moment, even steam is touched to user's hand carelessly, because the velocity of flow, the pressure of steam are lower, consequently, the user can move away the hand fast, makes the steam volume of hand contact in unit interval show and reduce, promotes the utility model discloses a security.

It should be noted that, the food processing machine in this embodiment may be an "electric cooker" for cooking food, during cooking, food and water are placed in the container, the cooking assembly includes an electric heating element disposed at the bottom of the lower housing, the electric heating element heats the food and water in the container to form a cooking effect of "cooking" or "stewing", and at this time, a large amount of steam is generated by the boiling water or soup. Of course, the food processor in this embodiment may also be an electric steamer, or even a steam air-fry, in this case, the cooking assembly may include a steam generator disposed at the bottom of the lower housing to generate a large amount of steam to "steam" the food material in the container; or, a vessel such as a bowl for containing water and food materials can be placed in the container, the cooking assembly comprises an electric heating element arranged at the bottom of the lower shell, and the electric heating element enables the water in the container to be boiled to generate a large amount of steam, so that the food materials in the vessel are steamed.

As a preferable mode, as shown in fig. 2 and 3, we can make the depressurization channel form an abrupt change in radial direction with respect to the base channel, so as to form a depressurization step 43 between the base channel and the depressurization channel, the cross-sectional area of the open end of the base channel is S1, and the cross-sectional area of the end of the depressurization channel communicating with the steam outlet is S2, and we can control the ratio between the two in the following range: 1/10 is less than or equal to S1/S2 is less than or equal to 1/3.

When steam enters the pressure reduction channel through the basic channel, the cross section and the corresponding volume of the steam have an increasing sudden change, correspondingly, the air pressure of the steam has a remarkable reduction, and the steam after pressure reduction naturally escapes outwards from the steam outlet of the upper shell, so that the potential safety hazard caused by the steam is favorably reduced.

As another preferred solution, a water receiving tank 51 may be provided in the upper housing below the opening of the base passage. When high-temperature steam escapes outwards through the basic channel, the pressure reduction channel and the steam outlet, the temperature of the steam is gradually reduced, and therefore condensate water is easily formed in the steam channel. At this moment, the condensed water formed in the steam channel can be dripped into the water receiving tank below through the opening of the basic channel, so that the condensed water is prevented from dripping on food materials in the container to influence the taste.

It should be noted that, should have the clearance between the opening of basic passageway and the water receiving tank for in steam accessible clearance gets into basic passageway, avoid influencing the discharge of steam because of the setting of water receiving tank, and the heat of steam can heat the water receiving tank, make the comdenstion water in the water receiving tank evaporate after being heated, and outwards escape through the steam outlet, thereby avoid the comdenstion water to store up in the water receiving tank effectively.

Furthermore, as shown in fig. 2 and 4, a hot air assembly 22 for outputting hot air into a container below the hot air assembly and an oil shield 5 located below the hot air assembly may be further disposed at the middle part of the upper housing, and the oil shield is provided with a vent 52 for allowing hot air formed by the hot air assembly to pass through the oil shield, so that the food processor has a cooking function and an air fryer function to adapt to processing of different food materials. Of course, the oil shield is clamped with the upper shell. In addition, the water receiving groove protruding downwards can be arranged on the oil shield. Like this, the bellied water receiving tank down can play the effect of similar handle to make things convenient for the installation, the dismantlement and the washing of oil shield and water receiving tank.

In order to facilitate installation and positioning of the oil shield and the water receiving grooves, two water receiving grooves can be arranged on the oil shield, and the two water receiving grooves are arranged on the oil shield in a central symmetry manner. Therefore, a user can ensure that a water receiving groove is arranged below the steam channel no matter the user installs the oil shield in the forward direction or the reverse direction. That is to say, even the oil shield is rotated 180 degrees and is reversely installed in the upper shell, a water receiving groove is arranged below the steam channel, and the other water receiving groove simply plays the role of a handle, so that the oil shield can be conveniently lifted and taken when being disassembled and assembled.

Preferably, the bottom surface of the water receiving tank can be inclined upwards from inside to outside in the radial direction of the upper shell. Therefore, the condensed water dropping into the water receiving tank can naturally flow to one side of the water receiving tank close to the center of the upper shell. Because the hot air assembly is arranged at the center of the upper shell, the condensed water close to the center of the upper shell is heated by the hot air assembly to form steam more quickly and is discharged outwards, and the accumulation of the condensed water in the water receiving tank is effectively avoided.

As another preferred option, as shown in fig. 5, the pressure-reducing step may be inclined downward from the pressure-reducing channel to the base channel, i.e., a transition chamfer is formed between the pressure-reducing channel and the base channel.

The temperature of the steam in the whole steam channel is gradually reduced from the basic channel to the pressure reduction channel. Therefore, the condensate water is mainly formed in the pressure reducing channel, and when the condensate water is formed in the pressure reducing channel, the condensate water can conveniently flow downwards into the basic channel along the inclined chamfer angle and drop into the water receiving tank, so that the condensate water is effectively prevented from accumulating at the pressure reducing step.

In order to avoid that excessive condensed water in the water receiving tank overflows and drops on food materials in a container below, as shown in fig. 2, 3 and 6, a water collecting tank 23 can be arranged in the upper shell, a downward water outlet interface 431 is arranged on a pressure reduction step of the steam channel, and the water outlet interface is communicated with the water collecting tank through a water drainage pipeline 24. Therefore, the condensed water formed in the pressure reducing channel can directly flow into the water collecting tank through the water outlet interface arranged on the pressure reducing step and the water discharging pipeline for storage.

It should be noted that we can increase the volume of the water collecting tank properly so as to make the water collecting tank store more condensed water and ensure that the food processor will not overflow and drip when it works continuously for a long time. In addition, this scheme can use alone, or also can use with the water receiving tank cooperation. When the water collecting tank is arranged independently, the ratio of the extrusion S1 to the extrusion S2 can be reduced as much as possible, and the condensate water is ensured to be only reserved on the pressure reduction step of the pressure reduction channel.

Preferably, the drainage pipeline is arranged to be inclined downwards from one end of the water outlet port to one end of the water collecting tank, so that condensed water is prevented from being accumulated in the drainage pipeline, and the drainage pipeline is ensured to be smooth.

In order to further improve the safety, as shown in fig. 7, a plurality of steam outlets may be eccentrically arranged on the top surface of the upper shell, and the steam outlets are radially arranged in a straight line on the upper shell, and in addition, one end of the depressurization channel, which is communicated with the steam outlets, is in an oblong shape, and the steam outlets arranged in a straight line are located in a corresponding area of the depressurization channel. That is, the cross section of the pressure-reducing channel that is oblong is also arranged radially on the upper housing.

Therefore, the user can keep away from the handle and other parts for opening the upper shell at the central position of the upper shell as far as possible, namely, the user can keep away from the steam discharged from the steam outlet as far as possible if the user wants to operate the upper shell when in use, thereby improving the safety of the steam outlet. And set up a plurality of steam outlets of a style of calligraphy range, under the same steam discharge amount, can make the exhaust region of steam spread as far as possible, avoid appearing steam and gather the effect, and then reduce the injury that causes when the user accidentally contacts steam.

Finally, a U-shaped lifting ring 25 can be arranged on the upper shell, two ends of the lifting ring are rotatably connected to two sides of the upper shell, the lifting ring is attached to the top surface of the upper shell, and at the moment, the steam outlet is eccentrically positioned on one side, away from the lifting ring, of the top surface of the upper shell.

The bail is convenient for a user to lift the food processor, and particularly, when the bail is attached to the top surface of the upper shell, the steam outlet is eccentrically positioned on one side of the top surface of the upper shell away from the bail, so that when the user needs to lift upwards and open the upper shell, the steam outlet can be kept away from the part holding the bail, thereby maximally avoiding the injury of the steam to the hand of the user.

It is understood that various changes and modifications other than those described in the preferred embodiments described above may be made by those skilled in the art without departing from the spirit of the invention, and the scope of the invention is defined by the appended claims.
