Description

grease pump

This application claims the priority of a Chinese patent application filed to the State Intellectual Property Office of China on June 15, 2020 with the application number "202010545431.1" and the invention title "Exhaust Hood", the entire content of which is incorporated into this application by reference middle.

Technical field

Background technique

Conventional European-style range hoods are provided with a condensing plate below the air inlet. In order to improve the effect of absorbing oil fume, the condensing plate and the front and left sides of the deflector of the range hood form channels with a fixed width for air flow. When the condensing plate has a lifting function, the larger the flow path between the condensing plate and the deflector is conducive to the rapid introduction of oil fume into the range hood.

When the burner is on, most of the oil fume only enters the range hood through the one-sided channel. Due to the uneven air flow, the one-sided flow channel cannot quickly suck the fume away.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other if there is no conflict.

In the following description, many specific details are set forth in order to fully understand this application. However, this application can also be implemented in other ways different from those described here. Therefore, the scope of protection of this application is not subject to the specific implementations disclosed below. Limitations of cases.

The range hoods according to some embodiments of the present application will be described below with reference to FIGS. 1 to 9.

Example one:

As shown in Figs. 1 to 4, a range hood includes a baffle 100 and a condensing assembly 200. The baffle 100 has an air inlet 110 and a smoke collecting cavity 120 that communicate with each other; the condensing assembly 200 is at least partially disposed in the smoke collecting cavity 120. The first flow channel 240 communicated with the tuyere 110. The condensing assembly 200 includes a first condensing plate 210, a second condensing plate 220 and a driving mechanism 230. The first condensing plate 210 is disposed on the side of the air inlet 110 facing the smoke collecting cavity 120; the second condensing plate 220 is disposed on the first condensing plate One side of 210, and abuts against the first condensing plate 210. The driving mechanism 230 is arranged in the smoke collecting cavity 120 and is connected to the first condenser plate 210 and/or the second condenser plate 220; the driving mechanism 230 is used to drive the first condenser plate 210 and the second condenser plate 220 to move away from each other and drive The first condensing plate 210 and/or the second condensing plate 220 move in translation to form a second flow channel 250 between the first condensing plate 210 and the second condensing plate 220.

In the range hood proposed in the present application, a second flow passage 250 is constructed between the first condensing plate 210 and the second condensing plate 220, which also increases the number of flow passages, which is conducive to improving the smoking effect of the range hood. The second runner 250 is located between the first condensing plate 210 and the second condensing plate 220, that is, the second runner 250 is more centered than the first runner 240, no matter which side of the stove is turned on, The second runners 250 are relatively close to the opening of the burner, which is convenient for sucking the oil fume near the burner, so that the oil fume enters the range hood faster, thereby improving the overall smoking efficiency of the range hood and preventing the oil fume from overflowing.

Specifically, the baffle 100 has an air inlet 110 and a smoke collecting cavity 120 that communicate with each other, so that the smoke collecting cavity 120 can guide the oil fume to the air inlet 110, and the oil fume can be sucked and discharged through the air inlet 110. The condensing assembly 200 is at least partially disposed in the fume collecting cavity 120, so that the rising oil fume first encounters the condensing assembly 200 to be condensed, so that the filter at the air inlet 110 can intercept the oil droplets in the fume. The condensing assembly 200 shields the air inlet 110, which can effectively block the oil and water dripping from the inside of the range hood. In addition, due to the large area of the condensing assembly 200, the negative pressure area at the bottom of the smoke collecting chamber 120 is expanded, and the condensing assembly A first flow passage 240 is formed between 200 and the baffle 100, which is beneficial to enhance the smoking ability around the range hood, and through the communication between the first flow passage 240 and the air inlet 110, the sucked oil fume is guided to the air inlet 110 to make The oil fume is discharged, and there is less oil fume overflow. The condensing assembly 200 includes a first condensing plate 210 and a second condensing plate 220. The first condensing plate 210 and the second condensing plate 220 are in contact with each other, which is beneficial to intercept the oil droplets dripping inside the range hood and prevent the oil droplets from directly falling on the stove On the stage; the driving mechanism 230 can drive the first condensing plate 210 and/or the second condensing plate 220 to move, so that the first condensing plate 210 and the second condensing plate 220 are separated from each other, and a second flow path is constructed between the two 250, so that the oil fume can also enter the air inlet 110 through the second runner 250, which is beneficial to improve the efficiency of oil fume absorption when a single burner is used or the oil fume is large. Moreover, it is specifically defined that the driving mechanism 230 can drive the first condensing plate 210 and/or the second condensing plate 220 to translate, which is beneficial to ensure the opening of the second flow channel 250 constructed between the first condensing plate 210 and the second condensing plate 220 Large enough to better absorb oil fume. Moreover, the translational movement is relatively simple, which is beneficial to simplify the structure of the driving mechanism 230. Compared with the related art, the first condensing plate 210 or the second condensing plate 220 can be turned over and partially extend into the smoke collecting cavity 120, which reduces the occupation of the internal space of the smoke collecting cavity 120 and does not affect the oil smoke in the smoke collecting cavity. Fast flow within 120. Moreover, compared with the solution of raising and lowering the condensing plate in the related art, since the translational movement is simpler, it is beneficial to simplify the structure of the driving mechanism 230, reduce the space occupied by the driving mechanism 230, and thereby help reduce the space occupied by the range hood. Reduce the cost.

It should be noted that in the present application, the condensing assembly 200 shields the air inlet 110, which does not mean that the smoke collecting cavity 120 and the air inlet 110 cannot be communicated, but when the condensing assembly 200 blocks the air inlet 110, such as the first condensing plate When 210 is in contact with the second condensing plate 220, the oil fume will not enter the air inlet 110 through the smoke collecting cavity 120 vertically, but will enter through the first flow passage 240 formed between the condensing assembly 200 and the baffle 100 The air inlet 110. When the driving assembly drives the first condenser plate 210 and the second condenser plate 220 to move away from each other, the condenser assembly 200 partially covers the air inlet 110 or does not block the air inlet 110. At this time, the first condenser plate 210 and the second condenser plate 220 are A second flow passage 250 is formed between the plates 220, which is beneficial for the oil fume to enter the air inlet 110 through the second flow passage 250 more quickly, and the efficiency of oil fume absorption is improved. Wherein, the first condensing plate 210 and the second condensing plate 220 abut, which is only the first smoking state of the range hood of the present application. By default, in the natural state, the range hood is in the first smoking state; the range hood can also be in the first smoking state. The second smoking state in which the first condensation plate 210 and the second condensation are separated from each other. In addition, the driving mechanism 230 can also drive the first condensing plate 210 and the second condensing plate 220 to approach each other, so that the first condensing plate 210 and the second condensing plate 220 abut and return to the first smoking state. The first condensing plate 210 is arranged on the side of the air inlet 110 facing the smoke collecting cavity 120, so that the first condensing plate 210 can be arranged in the smoke collecting cavity 120 or outside the smoke collecting cavity 120; The smoke cavity 120 has a smoke inlet, and the air inlet 110 is located at an end of the smoke collecting cavity 120 away from the smoke inlet.

In a specific application, as shown in Fig. 3, the first condensing plate 210 and/or the second condensing plate 220 can be driven by the driving mechanism 230 to translate left and right, that is, move in the horizontal direction of the range hood. Of course, in other embodiments, the first condensing plate 210 and/or the second condensing plate 220 may also be able to move up and down under the drive of the driving mechanism 230, that is, move in the height direction of the range hood.

In a specific application, as shown in Figures 1 and 2, when the cooking fume on both sides of the burner is relatively small, the first condensing plate 210 and the second condensing plate 220 of the range hood abut, that is, they are merged and flushed. , The oil fume flows to the air inlet 110 through the first flow passage 240 formed between the entire condensing plate integrated with the first condensing plate 210 and the second condensing plate 220 and the baffle plate 100.

When the oil fume continues to increase, it is necessary to switch the high gear, as shown in Figures 3 and 4, the first condensing plate 210 and/or the second condensing plate 220 are far away from each other, so that the first condensing plate 210 and the second condensing plate 220 are integrated Between the whole of the condensing plate and the baffle 100, and between the first condensing plate 210 and the second condensing plate 220, a plurality of flow passages, namely the first flow passage 240 and the second flow passage 250 are formed, so that the oil fume is in the multiple flows The middle of the road quickly enters the range hood, and quickly exhausts the range hood.

Moreover, the switching of the smoking status of the first condensing plate 210 and the second condensing plate 220 can be controlled by the operating gear of the range hood, for example, the first condensing plate 210 and the second condensing plate 220 are in the first smoking state in the low gear. , The first condensing plate 210 and the second condensing plate 220 are in the second smoking state when switched to the high gear. Or there are sensors, smoke detectors and other detection equipment on the back of the two condensing plates, in the smoke collecting cavity 120, and at the air inlet 110.
