Description

Multifunctional stove

Technical Field

The present application relates generally to kitchen cooktops and more particularly to a multi-function stove having both cooking and fume extraction functions.

Background

In commercial or other large scale cooking situations, a stove with a heating function alone cannot meet the complete cooking needs. In commercial cooking occasions such as household dinner, hotel catering, roadside snack stall and the like, the requirements of illumination, heat preservation, food material placement, oil smoke absorption, wind shielding, rain shielding and the like are met. Chinese patent application 201420387982.X proposes a multifunctional stove integrating a cooking bench, ice-cold cabinet, locker, canopy, etc. into one cooking device. However, such integration is simply a stacking of a plurality of functional modules, and there is no coordination relationship among the functional modules, particularly no coordination relationship of heat transfer, so that energy waste is easily caused.

The existing cooking equipment such as barbecue ovens, spicy hot ovens, noodle ovens and the like can generate a large amount of oil smoke in the cooking process, and in order to reduce the oil smoke, an oil smoke suction device is often arranged at the same time in such cooking occasions. The smoke inlet of the traditional upward-discharging type smoke absorbing device is 80 cm-100 cm higher than the height of the cooking operation table top, so that the sufficient operation space is ensured, and meanwhile, the effect of smoke absorbing is also ensured. The cooking fume generated by cooking is adsorbed on the pipe wall and fan blades of the range hood, so that thick oil stains are often formed, the range hood is difficult to clean, the smoking efficiency of the range hood can be influenced for a long time, and the service life of the range hood is shortened. In order to solve the problem of oil stain adhesion, chinese patent application 201610347271.3 proposes a fan runner non-sticky oil cleaning-free device, which sets up a water mist device inside the range hood, before the range hood absorbing oil smoke contacts the shell and the rotating wheel, the water mist device continuously sprays water mist particles, and forms the water film layer on the outer surface of the rotating wheel and the inner wall of the shell in advance, thereby preventing the adhesion of oil smoke. The nanometer coating UGT is arranged on the impeller and the impeller shell in the Chinese patent ZL 20182007370. X, and the adhesion of the oil smoke in the range hood is reduced by utilizing the advantages of UGT, water and oil resistance. However, UGT nanocoating is costly and difficult to maintain once it is shed.

In addition, the existing oil fume suction device is usually of an upward suction type, and the fume inlet of the oil fume suction device protrudes outwards to form a 7 shape, so that the upward suction type oil fume suction device can play a role in blocking oil fume because the hot oil fume is upwards dispersed and the fume inlet of the upward suction type oil fume suction device can be arranged at a position close to the vertical position of the movement path of the oil fume, and therefore, the upward suction type oil fume suction device can play a role in better absorbing the oil fume. Correspondingly, the oil way, the smoke suction port and the like of the up-draft type oil smoke device are large in area and length, and are difficult to miniaturize. In contrast, although the height of the smoke guide device of the down-draft smoke exhaust apparatus is 50-70 cm compared with the height of the table top of the furnace body, so that the volume of the down-draft smoke exhaust apparatus is relatively small, the smoke inlet of the down-draft smoke exhaust apparatus is difficult to be completely arranged on the motion path of the smoke due to the limitation of the height, and therefore, the effect of absorbing the smoke by the down-draft smoke exhaust apparatus is often poor.

In order to achieve the effects of safety, attractive appearance, foreign matter entering prevention and the like, the fume exhaust device is generally provided with a protective net at a fume inlet. For the downward-suction type fume exhaust device, since the fume exhaust port is arranged at a lower position, when cooking operation is performed, limbs of an operator can easily touch the fume inlet, and foreign matters can also easily enter the fume exhaust port, so that a protective net of the fume inlet is often necessary for the downward-suction type fume exhaust device. And the mesh openings of the smoke inlet protective net of the downdraft type smoke absorbing device are usually arranged more densely so as to prevent oil drops, water drops and the like from entering. However, the dense protective net arranged at the smoke inlet can greatly reduce the effective area of the smoke inlet, and further reduce the smoke absorbing effect of the lower smoke absorbing type smoke exhaust device.

In the occasion of commercial kitchen range, the air intake of oil smoke absorbing device often has certain length, leads to the negative pressure of air intake different positions different, and the position negative pressure that keeps away from the fan often is too little, causes the excessive of oil smoke easily.

The present invention has been made in view of the above problems occurring in the conventional cooking devices, particularly, the problems of poor smoking effect and excessive soot of the downdraft type range hood.

At this point, the cooking fume inlet is still located close to the cooking location 110.

In this embodiment, the multi-function furnace 100 further includes a flue device, the housing of which forms a smoke evacuation channel. The flue arrangement comprises a deposition section 132 arranged along the length direction of the furnace body and a smoke evacuation section 133 arranged along the height direction of the furnace body. One end of the deposition section 132 is connected to the smoke inlet structure so that the smoke can enter the smoke exhaust passage through the smoke inlet 131, and the other end of the deposition section 132 is connected to the smoke exhaust section 133. One end of the smoke exhausting section 133 is connected with the deposition section 132, and the other end of the smoke exhausting section is provided with a smoke outlet. The fume outlet may be connected to a negative pressure generating device installed inside the furnace body of the multifunctional furnace 100, which in this embodiment is a blower 140. Optionally, the fan can be installed in an external connection mode, and the fan is connected to the oil smoke outlet of the smoke exhaust section.

As shown in fig. 2 and 3, blower 140 includes a blower cover 141, a blower screen 142, a blower housing 143, an oil pan 144, and a negative pressure source (not shown) including a fan and/or a worm gear. The fan filter screen 142 is arranged between the smoke exhausting section and the fan and is used for filtering the oil smoke entering the negative pressure generating device, reducing the oil smoke entering the negative pressure generating device and prolonging the service life of the negative pressure generating device. The fan filter 142 is detachably mounted to the fan housing 143, and as an alternative embodiment, the fan filter 142 is fixedly mounted to the fan housing 143, and the fan filter 142 and the fan housing 143 may be integrally detached and cleaned.

The oil receiving basin 144 is disposed at an opening of the blower housing 143, extends toward the inside of the blower housing, and is formed with a receiving space for receiving waste oil and waste water collected in the blower.

As an alternative embodiment, a handle (not shown) is arranged on the outer side of the oil receiving basin 144, so that the oil receiving basin can be conveniently taken out, installed and the like.

As shown in fig. 3, the deposition section 132 is inclined, and the height of the position where the deposition section is connected to the smoke inlet structure is higher than the height of the position where the deposition section is connected to the smoke outlet section 133. Specifically, the deposition segment 132 forms an oblique angle α with the horizontal plane, the oblique angle α being between 10 ° and 30 °. The junction of the deposition section 132 and the fume exhaust section 133 has an end-to-end spacing x from the end of the deposition section 132. By setting the tip interval x, a space accommodating chamber can be formed at the tip of the deposition section 132. The droplets, drops, etc. that condense inside the deposition section 132 are subjected to gravity, move along the inner wall of the deposition section pipe toward the end of the deposition section 132, and are collected in a receiving chamber at the end of the deposition section 132. At the end of the deposition section 132, a drain valve 134 is provided, which has two states, closed and open. In the closed state, the drain valve 134 remains sealed, avoiding loss of negative pressure in the exhaust duct, thereby ensuring the exhaust suction. In the open state, the drain valve 134 is opened to allow communication between the accommodating chamber at the end of the depositing section and the atmospheric pressure, so that the waste water, waste oil or other foreign matter collected therein flows out through the drain valve 134. Through such design, can conveniently collect and clear up multi-functional stove waste oil, the waste water that produces in the culinary art in-process, reduce multi-functional stove's maintenance cost, improve its life.

Due to space constraints, the deposition section 132 has a certain length and the end pitch x of the receiving chamber must be kept within a certain range. If x is too large, the distance of the deposition section 132 for condensing droplets is too small, resulting in insufficient collection of oil and water droplets in the deposition section 132, increasing the pressure of the blower and reducing the service life of the blower. If x is set too small, the volume of the receiving chamber at the end is too small, and frequent maintenance of the receiving chamber is required. The effective receiving volume of the receiving chamber is also related to the angle of inclination α of the deposition section 132. With the same tip spacing x, the greater the angle of inclination of the deposition segment, the greater the effective receiving volume of the receiving chamber at its tip. The product of the included angle α of inclination of the deposition segment 132 and the end spacing x in this embodiment has a value between 100 and 900. By adopting the parameter setting, the deposition section has stronger capability of condensing liquid drops, the dirt collecting pressure of the fan is reduced, meanwhile, the space of the accommodating chamber at the tail end of the deposition section has larger space, and the maintenance frequency is reduced.

Referring to fig. 4 to 7, the multifunctional furnace further includes a wind deflector 135, and the wind deflector 135 is mounted to the smoke inlet structure, in particular, the wind deflector is mounted on the smoke inlet 131. The wind guard 135 is provided with a plurality of openings, at the positions of which negative pressure is generated, through which soot enters the smoke exhaust passage. These openings have a certain exhaust area. The area of the openings per unit area of the wind deflector is defined as the unit exhaust area. The position of the wind shield 135 near the smoke exhaust passage is the smoke exhaust proximal end (end a), and the unit exhaust area of the smoke exhaust proximal end is smaller than the unit exhaust area of the smoke exhaust distal end (end B). Since the smoke inlet 131 of the multifunctional furnace has a certain length, the negative pressure at the smoke discharging proximal end (a end) of the smoke inlet 131 is stronger than the negative pressure at the smoke discharging distal end (B end). By setting the unit exhaust area of the smoke exhaust near end to be smaller than the unit exhaust area of the smoke exhaust far end, the negative pressure at each opening of the whole smoke inlet can be basically kept consistent, the loss of the negative pressure at the smoke exhaust near end is reduced, and the phenomenon that the oil smoke generated at the cooking position near the smoke exhaust far end (B end) overflows due to insufficient negative pressure of the smoke exhaust far end is avoided.

Fig. 4 and 5 show a wind deflector design in the first embodiment, in which the opening of the wind deflector 135 is circular, and the diameter of the opening near the smoke exhaust proximal end (section a) of the smoke exhaust channel is smaller than the diameter of the opening far from the smoke exhaust distal end (end B) of the smoke exhaust channel, so that the unit exhaust area of the smoke exhaust proximal end is smaller than the unit exhaust area of the smoke exhaust distal end.

Fig. 6 shows another design of wind deflector, wherein the openings in wind deflector 135 are rectangular, and the size of each opening is consistent. The spacing between the openings at the proximal end of the smoke (end A) near the smoke passageway is greater than the spacing between the openings at the distal end of the smoke (end B) far from the smoke passageway so that the unit exhaust area at the proximal end of the smoke is less than the unit exhaust area at the distal end of the smoke.

Fig. 7 shows another design of a wind deflector, in which a single opening is provided in the wind deflector 135. The width of the opening at the proximal end of the smoke evacuation (end a) near the smoke evacuation channel is smaller than the width of the opening at the distal end of the smoke evacuation (end B) far from the smoke evacuation channel, so that the unit exhaust area of the proximal end of the smoke evacuation is smaller than the unit exhaust area of the distal end of the smoke evacuation.

Fig. 8 to 13 are schematic views of a second embodiment of the present patent. The multifunctional furnace 200 comprises a furnace body, wherein the furnace body comprises a table surface 201, a control panel 202, a cabinet door 203 and side plates 204. The oven body is provided with a cooking location 210 where cooking equipment may be placed to effect heating of the food material. As shown in fig. 9, the multifunctional furnace further comprises a smoke inlet structure, wherein the smoke inlet structure comprises a smoke inlet 231 formed on the table 201 and a smoke collecting part 236 connected with the smoke inlet, and the smoke collecting part 236 is used for collecting the smoke entering from the smoke inlet 231. In the embodiment, the smoke gathering part is in an inverted trapezoid shape with a large upper part and a small lower part, and the larger opening area at the upper end of the smoke gathering part can be matched with the smoke inlet to absorb the oil smoke as much as possible. The smaller opening area of the lower end of the smoke gathering part can be matched with the smoke discharging channel of the multifunctional furnace, so that the convenience of assembly is improved and the material cost is reduced. In this embodiment, since the smoke exhaust passage 232 is disposed at the center of the smoke inlet, the negative pressure near the middle of the smoke inlet is greater than the negative pressure on both sides.

The smoke guide 220 of fig. 8 is disposed near the cooking location for guiding the cooking fumes generated at the cooking location. The smoke guide 220 includes vertical baffles 221 and horizontal baffles 222. The vertical baffle 221 is inclined towards the cooking position 210 with an angle θ between the vertical baffle 221 and the plane of the table top, the angle value being in the range 65 ° to 85 °, θ preferably 70 ° to 80 °, in particular θ is 75 °. As an alternative embodiment, in case the table top itself has a certain inclination angle, the vertical barrier 221 has an angle of 65 ° to 85 ° with the horizontal plane, which angle is preferably 70 ° to 80 °, in particular 75 °.
