Smoke machine

Technical Field

The utility model relates to a kitchen utensil's technical field specifically, relates to a cigarette machine.

Background

With the improvement of the living standard of people, the requirement of a user on a kitchen is continuously improved, and the experience of a cigarette machine becomes a pursuit trend in modern life.

In order to improve the oil smoke absorption effect of a range hood, the range hood on the market at present mostly adopts a method of increasing air intake or increasing air pressure. The two methods are realized by increasing the rotating speed of the fan or increasing the diameter of the impeller.

Although the method can improve the oil smoke absorption effect of the range hood, the disadvantages are obvious. One of them is that the volume of the cigarette machine becomes large, which makes the installation position of the cigarette machine limited. Secondly, the cost of the cigarette making machine is greatly increased, so that the market competitiveness of the cigarette making machine is reduced. And thirdly, the noise of the cigarette machine becomes large, thus reducing the use experience of users.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art at least partially, the utility model provides a cigarette making machine. The range hood comprises a smoke collecting hood and an air box assembly connected to the top of the smoke collecting hood, a main fan is arranged in the air box assembly, an air inlet communicated with the main fan is formed in the smoke collecting hood, the range hood further comprises an air deflector and an auxiliary fan, the air deflector and the auxiliary fan are arranged on the smoke collecting hood, the auxiliary fan and the air inlet are respectively located on two sides of the air deflector, and an auxiliary air outlet of the auxiliary fan is opposite to the air inlet.

The sub-fan may be disposed outside the bellows assembly so that it is an independent structure with respect to the main fan, both of which independently suck soot, and the soot discharged from the sub-fan may enter the main fan along substantially the same trajectory as the soot sucked into the main fan. From the aerodynamic perspective, the two parts do not invade each other, so that the range hood can be ensured to have a plurality of oil smoke absorption parts, the oil smoke is difficult to escape, and the oil smoke absorption effect is improved. Moreover, the auxiliary fan does not need to be provided with an independent discharge channel, so that the structure of the range hood is simpler and the cost is low. Moreover, the main fan does not need to be changed, and by reasonable arrangement, the auxiliary fan with small power and size can be selected. Thus, the cost of the cigarette machine is not increased remarkably. The auxiliary fan is arranged at the gap position on the range hood, so that the overall size of the range hood does not need to be increased, and the mounting position of the range hood is not limited. Moreover, the noise of the auxiliary fan is very low, the whole noise of the cigarette machine cannot be increased, and the use experience of a user is better.

Illustratively, the air deflector has a guiding position, and the air outlet direction of the auxiliary fan is along the air deflector at the guiding position. Through the arrangement, the airflow blown out by the auxiliary fan can enter the air inlet along the air deflector. The air flow directly sucked into the air inlet approaches the air deflector from bottom to top and moves towards the air inlet under the guidance of the air deflector. Therefore, the airflow blown out by the auxiliary fan and the airflow which is about to directly enter the air inlet can both move forwards along the air guide plate, and the interference of the air outlet of the auxiliary fan on the airflow which directly enters the air inlet is avoided. Thus, the problems of airflow disorder, noise increase and the like can be prevented. And, at the wind speed V of the sub-fan₂In the same case, this embodiment will result in a greater superimposed wind speed V₀Therefore, the oil smoke absorption effect is better and remarkable.

The air deflector is arranged at the air guiding position, the air deflector is positioned above the secondary air outlet and the air inlet, and the secondary air outlet is opposite to the upper part of the air inlet, so that air flow from the secondary air outlet enters the smoke collecting hood from the upper part of the air inlet. Although the airflow at the surface of the auxiliary air outlet is accelerated only for the airflow entering from the upper part of the air inlet, in practice, after the air speed at the upper part of the air inlet is increased, negative pressure is formed at the upper part, and the negative pressure drives the surrounding airflow to flow to the upper part, so that the air speed is increased integrally. Experiments show that the effect of absorbing the oil smoke is remarkably improved. In addition, in general, the air speed of the air flow entering the air inlet is higher in the middle area of the air inlet, and the air speed in the edge area is relatively lower; and under the condition of not opening the auxiliary fan, the wind pressure close to the wind deflector and the auxiliary fan is lower, so that the influence of the wind speed increased aiming at the upper part of the air inlet on the airflow directly entering the air inlet is smaller. Thus, the problems of airflow disorder, noise increase and the like can be prevented.

The air deflector also has a closed position, the air deflector is movable between the closed position and the air deflecting position, and the air deflector moves below the air inlet when in the closed position to cover the air inlet. Through the arrangement, when the cigarette machine does not work, the air inlet can be covered, so that peculiar smell in the cigarette machine can be prevented from being emitted to the outside of the cigarette machine, and the health of a user is harmed.

Illustratively, the air deflection plate is pivotally connected to the hood about a pivot axis to pivot between a closed position and an air deflection position, the secondary fan is located on a side of the pivot axis, and the secondary air outlet is located below the air deflection plate. Through the arrangement, the cigarette machine is simple in structure and low in cost. And the auxiliary fan is arranged on one side of the pivot, so that the space of the range hood can be utilized as much as possible, and the whole size of the range hood is ensured not to be increased.

Illustratively, the air inlet comprises a left air inlet and a right air inlet, the auxiliary fan comprises a left auxiliary fan and a right auxiliary fan, the air deflector comprises a left air deflector and a right air deflector, the left auxiliary fan is positioned on the left side of the left air inlet, the left air deflector is positioned between the left auxiliary air outlet and the left air inlet of the left auxiliary fan, the right auxiliary fan is positioned on the right side of the right air inlet, and the right air deflector is positioned between the right auxiliary air outlet and the right air inlet of the right auxiliary fan. Through the arrangement, the range hood can completely cover the upper parts of the two furnace ends, and the air inlets close to the range hood can absorb oil smoke according to the difference of the oil smoke source directions, so that the distance of absorbing the oil smoke is shortened, the oil smoke generated by cooking can be absorbed favorably, and the effect of absorbing the oil smoke is enhanced.

Exemplarily, the wind speed V of the main fan₁And the wind speed V of the auxiliary fan₂Satisfies the following conditions: k is a radical of₁V₁＜V₂＜k₂V₁，k₁∈[0.40，0.50]，k₂∈[1.30，1.40]. Thus, the superimposed wind speed V of the smoke machine₀Is more obvious and has higher input-output ratio. That is, the main fan and the sub-fan work together, and when the relation is satisfied, the significantly increased superimposed wind speed V can be obtained at the air inlet of the range hood₀. Therefore, the oil smoke suction effect of the range hood can be obviously improved.

Exemplarily, there is a superimposed wind speed V at the air intake₀，V₀、V₂And V₁Satisfies the following conditions: v₂＝k₃V₀-V₁，k₃∈[1.40，1.50]. The wind speed V of the main fan is taken as the wind speed V of the main fan through the relational expression₁And the wind speed V of the auxiliary fan₂Given this knowledge, the superimposed wind speed V can be calculated₀. This brings convenience to the parameter design of the cigarette machine. Superimposed wind velocity V₀Usually has a decisive influence on the soot absorption effect of the range hood, so that at the desired superimposed wind speed V₀Under the determined condition, the parameters of the auxiliary fan can be calculated, so that the type selection design of the auxiliary fan is facilitated, and particularly when the auxiliary fan is additionally arranged on the basis of the conventional range hood, great convenience is brought, the design difficulty is reduced, the design period is shortened, and good predictability is achieved.

Illustratively, the range hood further comprises a controller electrically connected to the main fan and the auxiliary fan, the controller for controlling the main fan and the auxiliary fan to operate simultaneously based on a predetermined signal. Through the arrangement, the main fan and the auxiliary fan can be started simultaneously, and the smoke machine can be more intelligent by matching with other components.

Illustratively, the cigarette machine is also provided with an operating member which is electrically connected with the controller, and the operating member is used for responding to the operation of a user to generate a preset signal and sending the signal to the controller. Through the arrangement, the cigarette machine is simple to operate and convenient to use

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

In order to improve the smoking effect of cigarette machine, can eliminate some drawbacks, according to the utility model discloses an aspect provides a cigarette machine. The range hood is provided with an auxiliary fan to improve the oil smoke absorption effect.

Figures 1-4 illustrate a range hood 100 according to one embodiment of the present invention. As shown in fig. 1-4, the range hood 100 can include a smoke collection hood 200, a windbox assembly 300, a wind deflector 500, and a secondary fan 600.

A main blower 400 may be disposed within bellows assembly 300. The main blower 400 may employ various types of blowers known in the art or may come into existence in the future as long as it can suck oil smoke. The structure for providing the main blower 400 within the bellows assembly 300 is well known in the art and will not be described in further detail herein.

The bellows assembly 300 may be attached to the top of the smoke collection cage 200 by any suitable means, such as welding, fastener attachment, and the like. The fume collecting hood 200 may be provided with an air inlet 210. The intake vent 210 may communicate with the main blower 400. That is, the soot can be sucked into the main fan 400 through the intake vent 210 of the smoke collecting cover 200 and then discharged to the outside or the flue through the main fan 400.

The fume collecting hood 200 is further provided with an air deflector 500 and an auxiliary fan 600. For example, the air deflector 500 may be fixedly or movably disposed on the smoke collection cage 200. The air guide plate 500 can guide the oil smoke, so that the oil smoke can pass through the air inlet 210 at a smoother angle. The sub-fan 600 may employ various types of fans known in the art or may come into existence in the future as long as it can suck oil smoke. Preferably, the sub-fan 600 may be a centrifugal fan. The centrifugal fan has the advantages of convenient maintenance, low noise, difficult corrosion and the like. The sub-fan 600 may be provided at any suitable position on the smoke collecting hood 200. In the embodiment shown in the drawings, the sub-fan 600 is disposed inside the smoke collecting hood 200. The smoke collection cover 200 may be provided with a secondary air inlet 614. The oil smoke may be sucked into the sub-fan 600 through the sub-inlet 614 and then discharged through the sub-outlet 612 of the sub-fan 600. The secondary air outlet 612 may be disposed on the fume collecting hood 200, or may be disposed outside the fume collecting hood 200. In other embodiments not shown, the secondary fan 600 may be disposed outside the fume collecting hood 200, so that the corresponding air opening is not required to be disposed on the fume collecting hood 200.

The same or different types of fans may be used for the sub-fan 600 and the main fan 400. Preferably, the secondary fan 600 may have less power than the primary fan 400. The sub-fan 600 and the air inlet 210 may be respectively located at both sides of the air guide plate 500. The secondary air outlet 612 of the secondary blower 600 may be disposed opposite to the air inlet 210, so that the air flow blown from the secondary air outlet 612 may enter the air inlet 210. In the cigarette maker 100 shown in figures 3-4, the secondary air outlet 612 may be disposed at an angle relative to the air inlet 210. In the cigarette maker 100' shown in figures 6-7, the secondary air outlet 612 and the air inlet 210 may be disposed nearly face-to-face with each other, i.e., they are disposed nearly parallel to each other and face each other. No matter what way the two are arranged oppositely, the oil smoke exhausted from the auxiliary air outlet 612 can enter the main fan 400 through the air inlet 210.

When the range hood 100 operates, a portion of the soot may be drawn into the main fan 400 through the intake opening 210 and then discharged to the outside or a flue through the main fan 400. Another portion of the soot may be sucked into the sub-fan 600, and then discharged to the intake port 210 through the sub-outlet 612 of the sub-fan 600, and further sucked into the main fan 400, and then discharged to the outside or a flue through the main fan 400.

The sub-fan 600 may be disposed outside the bellows assembly so that it is an independent structure with respect to the main fan 400, both of which independently suck the soot, and the soot discharged from the sub-fan 600 may enter the main fan 400 along substantially the same trajectory as the soot sucked into the main fan 400. From the aerodynamic perspective, the two parts do not invade each other, so that the range hood 100 can be ensured to have a plurality of oil smoke absorption parts, the oil smoke is difficult to escape, and the oil smoke absorption effect is improved. Moreover, the auxiliary fan 600 does not need to be provided with an independent discharge channel, so that the structure of the range hood 100 is simpler and the cost is low. Also, the main blower 400 does not need to be changed, and by proper arrangement, the sub-blower 600 having a small power and size can be selected for use. In this manner, the cost of the cigarette maker 100 does not rise significantly. The secondary fan 600 is disposed at a gap position on the range hood 100, and it is possible to ensure that the installation position of the range hood 100 is not limited without increasing the overall size of the range hood 100. Moreover, the noise of the auxiliary fan 600 is very low, the whole noise of the range hood 100 is not increased, and the user experience is good.

In a preferred embodiment, the cigarette maker 100 may further include a controller (not shown). The controller may be electrically connected to the main fan 400 and the sub-fan 600. The controller may be configured to control the main fan 400 and the sub-fan 600 to operate simultaneously based on a predetermined signal. The predetermined signal may be generated by a variety of means, such as a button, voice recognition, sensor, etc. With this arrangement, the primary fan 400 and the secondary fan 600 may be activated simultaneously and cooperate with other components to make the range hood 100 more intelligent.

Two preferred embodiments of generating the predetermined signal are described below:

optionally, the range hood 100 may also be provided with an operating member (not shown). The operating members include, but are not limited to, buttons, switches, touch screens, and the like. The operating member may be electrically connected to the controller. The user can control the operating member so that the operating member generates the predetermined signal and transmits the predetermined signal to the controller. With this arrangement, the cigarette maker 100 is relatively simple to operate and convenient to use. For example, when a user is stir-fried or when indoor smoke is large, the operation member may be manually operated to turn on the sub-fan 600.

Optionally, a sensor (not shown) may also be provided on the cigarette maker 100. Sensors include, but are not limited to, temperature sensors, smoke sensors, and the like. The sensor may be electrically connected to the controller. The sensors may be used to detect environmental information (e.g., temperature) about the range hood 100 and transmit the information to the controller. The controller may be configured to generate the predetermined signal based on environmental information. Through this arrangement, the range hood 100 is more intelligent and convenient to use.

It is to be noted that the above embodiments only describe the operation modes for improving the oil smoke suction effect of the range hood 100, and the range hood 100 may have other operation modes according to actual use situations. For example, if the soot is very small, only the sub-fan 600 may be operated to discharge the soot. For example, if the soot is not very large, the soot may be discharged by operating only the main fan 400.

The wind speed of the main fan 400 is set to V₁The wind speed of the auxiliary fan 600 is V₂The superimposed wind speed at the wind inlet 210 is V₀. The superimposed wind velocity V₀The wind speed of the main fan 400 is V₁And the wind speed of the sub-fan 600 is V₂In the case of (a), the wind speed measured at the wind inlet 210. That is, when the main fan 400 and the sub-fan 600 draw oil smoke together, the sub-outlet 612 of the sub-fan 600 draws wind at the wind speed V₁The discharged oil smoke and the main fan 400 is driven at the wind speed V₂When absorbing the oil smoke, V can be obtained at the air inlet 210₀The superimposed wind speed.

The inventor uses the wind speed V of the main fan 400₁13m/s is taken as a test basis, and the wind speed V of the auxiliary fan 600 is changed₂Respectively measuring the superimposed wind speed V₀The numerical value of (c). Specific values are shown in table 1. At the same time, the wind speed V in the table 1 is adjusted₂Sum of superimposed wind speeds V₀The relationship of (a) is plotted in a graph, see fig. 5.

Table 1:

through the test, the inventor finds that: referring to table 1 and fig. 5, the wind speed V of the main fan 400₁13m/s, wind speed V of the secondary fan 600₂When less than 5.5m/s, V₀And V₁Are almost equal. That is, the wind speed V of the sub-fan 600₂When the wind speed is less than 5.5m/s, the secondary fan 600 has almost no superimposed effect on the wind speed at the wind inlet 210 even when being started. When V is₂When it is greater than 5.5m/s, V₀With V₁The increase in (c) is a straight-line upward trend. I.e. secondary windWind speed V of machine 600₂When the wind speed is more than 5.5m/s, the superposition effect of the wind speed at the wind inlet 210 is obvious, and V is₀Relative to V₂Increasing almost proportionally.

Through the above analysis and multiple tests, the inventor found that the wind speed V of the main fan 400 is the same as the wind speed V of the main fan₁And the wind speed V of the sub-fan 600₂Satisfies the following conditions: k is a radical of₁V₁＜V₂，k₁∈[0.40，0.50]In the meantime, the superimposed wind speed V measured at the air inlet 210₀Will follow the wind speed V₂The increase of the number of the layers is remarkably increased, and the superposition effect is remarkable.

Further testing of the cigarette machine 100 indicated in the test data not shown when V₂＜k₂V₁，k₂∈[1.30，1.40]When, V₀With V₁The increase in (c) rises relatively slowly. I.e. the wind speed V of the secondary fan 600₂Greater than k₂V₁In time, the wind speed superposition effect at the air inlet 210 is general. That is, in terms of increasing the wind speed at the wind inlet 210, although it is also possible to increase V to some extent₀However, the "input-output ratio" is low, which may cause negative effects in increasing the power and volume of the auxiliary fan 600, increasing energy consumption and noise, and the like. Therefore, the inventors selected the above range in consideration of various factors.

In summary, when the wind speed V of the main fan 400 is higher than the wind speed V₁And the wind speed V of the sub-fan 600₂Satisfies the following conditions: k is a radical of₁V₁＜V₂＜k₂V₁，k₁∈[0.40，0.50]，k₂∈[1.30，1.40]In time, the superimposed wind speed V of the smoke machine 100₀Is more obvious and has higher input-output ratio. That is, the main blower 400 and the sub-blower 600 work together, and when the relation is satisfied, a significantly increased superimposed wind speed V can be obtained at the inlet 210 of the range hood 100₀. Accordingly, the range hood 100 can have a significantly improved range hood effect.

The inventor obtains the wind speed V of the main fan 400₁Wind speed V of the auxiliary fan 600 at three wind speed points of 8m/s, 10m/s and 12m/s₂Taking 12 points from 5.5-16.5, and dividingRespectively measuring the superposed wind speed V₀The numerical value of (c). Specific values are shown in Table 2.

Table 2:

through the analysis of Table 2, the inventors found V₀、V₂And V₁Satisfies the following conditions: v₂＝k₃V₀-V₁，k₃∈[1.40，1.50]。

That is, the wind speed V of the main fan 400 is determined by the relation₁And the wind speed V of the sub-fan 600₂Given this knowledge, the superimposed wind speed V can be calculated₀. This facilitates the design of the parameters of the range hood 100. Superimposed wind velocity V₀Generally has a decisive influence on the soot absorption effect of the range hood 100, and therefore at the desired superimposed wind velocity V₀Under the determined condition, the parameters of the auxiliary fan 600 can be calculated, so that the type selection design of the auxiliary fan 600 is facilitated, and particularly when the auxiliary fan 600 is additionally arranged on the basis of the existing range hood, great convenience is brought, the design difficulty is reduced, the design period is shortened, and good predictability is achieved.

As previously described, the wind deflection plate 500 may have a wind deflection position. Alternatively, the air guide plate 500 may be fixed at the air guide position, and the position is not variable. Alternatively, the air deflection plate 500 may be movable between an air deflection position and a closed position, as will be described in detail below with reference to specific embodiments. When the air deflector 500 is in the air guiding position, the air outlet direction of the sub-fan 600 may preferably be along the air deflector 500 in the air guiding position, as shown in fig. 7.

With this arrangement, the airflow from the secondary fan 600 can enter the air inlet 210 along the air deflector 500. The airflow directly sucked into the air inlet 210 approaches the air deflector 50 from the bottom to the top0 and moves toward the intake vent 210 under the direction of the air guide plate 500. Therefore, compared with the air outlet direction of the auxiliary blower 600 shown in fig. 3 to 4, both the airflow blown out by the auxiliary blower 600 of this embodiment and the airflow that is about to directly enter the air inlet 210 can move forward along the air deflector 500, so as to avoid the interference of the air outlet of the auxiliary blower 600 on the airflow directly entering the air inlet 210. Thus, the problems of airflow disorder, noise increase and the like can be prevented. And, the wind speed V at the sub-fan 600₂In the same way, the embodiments shown in fig. 6-7 result in a greater superimposed wind speed V than the previous embodiments₀Therefore, the oil smoke absorption effect is better and remarkable.

Alternatively, as shown in fig. 6-7, the air deflection plate 500 in the air deflection position may be positioned above the secondary air outlet 612 and the air inlet 210. The directional terms "upper" and "lower" as used herein are relative to the user when the machine 100 is in use. The secondary outlet 612 is opposite the upper portion of the intake vent 210 such that airflow from the secondary outlet 612 enters the smoke collecting hood 200 from the upper portion of the intake vent 210. The inventor found that although the airflow at the sub-outlet 612 on the surface is accelerated only by the airflow entering from the upper portion of the air inlet 210, in practice, when the air speed at the upper portion of the air inlet 210 is increased, a negative pressure is formed at the upper portion, and the negative pressure drives the surrounding airflow to flow thereto, thereby increasing the air speed as a whole. Experiments show that the effect of absorbing the oil smoke is remarkably improved. In addition, in general, the air flow entering the air inlet 210 has a large air speed in the middle area of the air inlet 210 and a relatively small air speed in the edge area; also, without opening the sub-fan 600, the wind pressure near the wind guide plate 500 and the sub-fan 600 is low, and thus, increasing the wind speed with respect to the upper portion of the air inlet 210 has less influence on the airflow directly entering into the air inlet 210. Thus, the problems of airflow disorder, noise increase and the like can be prevented.

The embodiment shown in fig. 6-7 differs from the embodiment shown in fig. 3-4 only in the mounting location of the secondary fan 600, and therefore, the same reference numerals are used for the same or similar components of the embodiment shown in fig. 6-7 as those of the embodiment shown in fig. 3-4, and a detailed description of these same or similar components will not be provided herein for the sake of brevity.

Preferably, referring back to fig. 2-4, the deflector 500 can also have a closed position. The air guide plate 500 can move between the closed position and the air guide position in various ways such as lifting and turning. The air deflector 500 may be moved below the intake vent 210 when in the closed position. The air guide plate 500 may cover the air inlet 210. With this arrangement, the air inlet 210 may be covered when the range hood 100 is not in operation, so that it is possible to prevent the odor inside the range hood 100 from being emitted to the outside of the range hood 100, thereby endangering the health of the user.

Further, as shown in fig. 1-4, the air deflection 500 may be pivotally connected to the smoke collection cage 200 about a pivot axis. The air deflection plate 500 is pivotable between a closed position and an air deflection position. The sub-fan 600 may be located at a side where the pivot is located. Meanwhile, the secondary air outlet 612 may be located below the air guide plate 500. With this arrangement, the cigarette maker 100 is compact in construction and low in cost. In addition, the auxiliary fan 600 is arranged at one side of the pivot, so that the space of the cigarette making machine 100 can be utilized as much as possible, and the whole size of the cigarette making machine 100 is ensured not to be increased.

Preferably, as shown in fig. 1 to 4, the intake vent 210 may include a left intake vent 211 and a right intake vent 212. The sub-fan 600 may include a left sub-fan 601 and a right sub-fan 602. The wind deflector 500 may include a left wind deflector 501 and a right wind deflector 502. The left sub-fan 601 may be positioned at the left side of the left intake vent 211.
