Abstract
Description
Technical Field
[0001] This application relates to the technical field of kitchen utensils, particularly to an exhaust device and a cooking system. Background Art
[0002] Built-in cooktops are deeply loved by users due to their simple and tidy appearance and space-saving advantages, and are gradually becoming the first choice for more and more families. A built-in cooktop includes a gas supply device (i.e., a natural gas pipeline and / or a gas stove), and the gas supply device is installed in a cabinet. However, when the gas supply device ages or the connection loosens, slight gas leakage may occur. Since the leaked gas is less and the ventilation of the cabinet is very poor, the leaked gas accumulates in the cabinet, and it is not easy for users to detect, which will pose a safety hazard. Although maintenance personnel will regularly visit to check and eliminate this safety hazard, during the period between two regular visits, there may be a relatively high concentration of gas or natural gas accumulated in the cabinet. In other words, this safety hazard will exist during the period between two regular inspections. Summary of the Utility Model
[0003] Based on this, in view of the above problems, it is necessary to provide an exhaust device and a cooking system. The exhaust device can discharge the gas in the cabinet to the outside, so as to discharge the leaked gas out of the cabinet, thereby facilitating users to detect gas leakage, reducing the concentration of gas in the cabinet, and preventing safety accidents.
[0004] To solve the above problems, the technical solutions provided by this application are as follows:
[0005] An exhaust device, which includes:
[0006] A filter, having a flow channel;
[0007] A water-driven impeller, installed in the flow channel. When water flows through the flow channel and the water in the flow channel is in a flowing state, the water flow drives the water-driven impeller to rotate around the axis of the water-driven impeller;
[0008] A rotating shaft, fixedly arranged on the water-driven impeller and coaxially arranged with the water-driven impeller. The rotating shaft penetrates through the filter;
[0009] A shaft seal, arranged on the filter, used to seal the gap between the filter and the rotating shaft;
[0010] A fan impeller, fixedly arranged on the rotating shaft, located outside the filter and coaxially arranged with the water-driven impeller. The air outlet direction of the fan impeller is along the direction away from the water-driven impeller; and
[0011] An exhaust pipe, sleeved outside the fan.
[0012] This exhaust device has at least the following beneficial effects:
[0013] On the cabinet for installing an embedded cooker, a water inlet pipe and a faucet are usually also installed. A part of the water inlet pipe is located inside the cabinet, and the faucet is located outside the cabinet. When using the exhaust device provided by the present application, the filter can be strung between the water inlet pipe and the faucet, and the exhaust pipe can pass through the cabinet, so that the space inside the cabinet, the air inlet of the exhaust pipe, the air outlet of the exhaust pipe and the outside are communicated in sequence. On the one hand, this can achieve the purification of domestic water. On the other hand, after the faucet is opened, the water flows through the flow channel, the impeller rotates around its own axis, thereby driving the fan impeller to rotate. The fan impeller drives the gas inside the cabinet to be discharged to the outside through the exhaust pipe. In this way, the gas leaked inside the cabinet can be discharged outside the cabinet, which is beneficial for the user to detect the gas leakage and reduce the concentration of gas inside the cabinet, preventing safety accidents from occurring.
[0014] In one embodiment, the distance between the inner wall of the exhaust pipe and the fan impeller is D, and D satisfies: D≤2mm.
[0015] With such a setting, it is beneficial for the airflow formed when the fan impeller rotates to flow along the exhaust pipe, which is beneficial for discharging the gas inside the cabinet to the outside.
[0016] In one embodiment, a plurality of the fan impellers are spaced apart on at least one of the rotating shafts.
[0017] With such a setting, the multiple fan impellers cooperate with each other, can generate a greater wind force, and are beneficial for discharging the gas inside the cabinet to the outside.
[0018] In one embodiment, there are a plurality of the water-driven impellers, the rotating shafts, the exhaust pipes and the fan impellers. Each water-driven impeller corresponds to one exhaust pipe, one rotating shaft and at least one fan impeller.
[0019] With such a setting, the respective fan impellers act together, which is beneficial for discharging the gas inside the cabinet to the outside.
[0020] In one embodiment, the lengths of the respective exhaust pipes are different.
[0021] With such a setting, when making full use of the lengths of the respective exhaust pipes, the air inlet of the exhaust pipe with a shorter length can be arranged at the upper part of the space inside the cabinet, and the air inlet of the exhaust pipe with a longer length can be arranged at the lower part of the space inside the cabinet, so as to discharge the gas at different heights inside the cabinet to the outside by using the respective exhaust pipes.
[0022] The present application also provides a cooking system, which includes:
[0023] A cabinet, which is provided with a receiving cavity inside, and the cabinet is provided with an avoidance hole communicated with the receiving cavity;
[0024] The water inlet pipe, partially located within the accommodation cavity;
[0025] The gas supply device, partially located within the accommodation cavity;
[0026] The faucet, located outside the cabinet; and
[0027] The above-mentioned exhaust device, the filter is installed within the accommodation cavity, the flow channel has a water inlet section and a water outlet section, the water inlet section supplies water to flow into the filter, the water outlet section supplies water to flow out of the filter, the water inlet pipe, the water inlet section, the water outlet section and the faucet are sequentially connected; the exhaust pipe passes through the avoidance hole, the exhaust pipe has an air inlet and an air outlet, and the accommodation cavity, the air inlet, the air outlet and the outside are sequentially connected.
[0028] This cooking system has at least the following beneficial effects:
[0029] After the faucet is opened, water flows through the flow channel, the impeller rotates around its own axis, thereby driving the fan impeller to rotate, and the fan impeller drives the gas in the cabinet to be discharged to the outside through the exhaust pipe. In this way, the gas leaked in the cabinet can be discharged outside the cabinet, which is beneficial for users to detect gas leakage and reduce the gas concentration in the cabinet, preventing safety accidents.
[0030] In one embodiment, there are multiple water-driven impellers, rotating shafts, exhaust pipes and fan impellers. Each water-driven impeller corresponds to one exhaust pipe, one rotating shaft and at least one fan impeller. The air inlets of each exhaust pipe are located at different heights, and the air inlet of at least one exhaust pipe is located within the accommodation cavity.
[0031] With such an arrangement, it is beneficial to discharge the gas at different heights within the accommodation cavity to the outside.
[0032] In one embodiment, the gas supply device includes a natural gas pipeline and a gas stove, and the cooking system includes multiple exhaust devices; wherein, at least one filter is located in the upper part of the accommodation cavity, and the air inlet of at least one exhaust pipe corresponding to the filter located in the upper part of the accommodation cavity is located within the avoidance hole, at least one filter is located in the lower part of the accommodation cavity, and the air inlet of at least one exhaust pipe corresponding to the filter located in the lower part of the accommodation cavity is located in the lower part of the accommodation cavity.
[0033] With such an arrangement, whether natural gas leakage or gas leakage occurs, after the faucet is opened, the leaked gas can be discharged to the outside.
[0034] In one embodiment, a plurality of the water-driven impellers, the rotating shafts, the exhaust pipes, and the fan impellers are provided. Each water-driven impeller corresponds to one exhaust pipe, one rotating shaft, and at least one fan impeller. At least one rotating shaft is located in the water inlet section, and at least one rotating shaft is located in the water outlet section. The difference between the number of rotating shafts located in the water inlet section and the number of rotating shafts located in the water outlet section is less than or equal to 1.
[0035] With such an arrangement, the respective rotating shafts are relatively evenly distributed in the water inlet section and the water outlet section, avoiding excessive concentration of the rotating shafts in the water inlet section / water outlet section, which is beneficial to ensuring the structural strength of the filter and preventing the structural strength at a certain part of the filter from being too small.
[0036] In one embodiment, the outer sides of the exhaust pipes are in contact with the hole walls of the avoidance holes everywhere.
[0037] With such an arrangement, the hole walls of the avoidance holes play a role in fixing the exhaust pipes, avoiding the need to additionally provide a structure for fixing the exhaust pipes. Description of the Drawings

[0042] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be made in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.
[0045] In the present application, unless otherwise clearly specified and limited, the terms such as "mounted", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.
[0048] Refer to Figure 1 and Figure 2 First, the present application provides an exhaust device, which includes a filter 1, a water impeller 2, a rotating shaft 3, a shaft seal, a fan impeller 4 and an exhaust pipe 5. The filter 1 has a flow channel 11, and the filter 1 is used for filtering water to achieve water purification. The water impeller 2 is installed in the flow channel 11. When water flows through the flow channel 11 and the water in the flow channel 11 is flowing, the water flow drives the water impeller 2 to rotate around the axis of the water impeller 2. The rotating shaft 3 is fixed to the water impeller 2 and is coaxially arranged with the water impeller 2. The rotating shaft 3 passes through the filter 1. The shaft seal is arranged on the filter 1 and is used for sealing the gap between the filter 1 and the rotating shaft 3. The fan impeller 4 is fixed to the rotating shaft 3, is located outside the filter 1, and is coaxially arranged with the water impeller 2. The air outlet direction of the fan impeller 4 is along the direction away from the water impeller 2. The exhaust pipe 5 is sleeved outside the fan.
[0049] On a cabinet 6 for installing an embedded cooker, a water inlet pipe and a faucet are usually also installed. A part of the water inlet pipe is located inside the cabinet 6, and the faucet is located outside the cabinet 6. When using the exhaust device provided by the present application, the filter 1 can be strung between the water inlet pipe and the faucet, and the exhaust pipe 5 can be passed through the cabinet 6 so that the space inside the cabinet 6, the air inlet 51 of the exhaust pipe 5, the air outlet 52 of the exhaust pipe 5 and the outside are connected in sequence. On the one hand, this can achieve the purification of domestic water. On the other hand, after the faucet is opened, the water flow passes through the flow channel 11, and the impeller rotates around its own axis, thereby driving the fan impeller 4 to rotate. The fan impeller 4 drives the gas inside the cabinet 6 to be discharged to the outside through the exhaust pipe 5. In this way, the gas leaked inside the cabinet 6 can be discharged outside the cabinet 6, which is beneficial for users to detect gas leakage and reduce the concentration of gas inside the cabinet 6 to prevent safety accidents.
[0050] It can be understood that the cabinet 6 is used for installing an embedded cooker and needs to be able to be opened at any time for repairing the gas supply device. Therefore, the cabinet 6 is not a closed space. While the fan impeller 4 discharges the gas inside the cabinet 6 to the outside, relatively fresh and clean air from the outside will enter the cabinet 6 through the gaps on the cabinet 6.
[0051] The shaft seal is a sealing device used to prevent fluid from leaking along the rotating shaft 3. The shaft seal in this application can adopt the prior art and will not be elaborated here.
[0052] The water-driven impeller 2 includes multiple blades. During the process of water flowing through the flow channel 11, the water hits each blade. In this application, the acting force of the water on the water-driven impeller 2 is not symmetrical. In other words, the resultant torque on the water-driven impeller 2 is not 0. In this way, the water-driven impeller 2 rotates around its own axis under the action of the torque.
[0053] The distance between the inner wall of the exhaust pipe 5 and the fan impeller 4 is D. Preferably, D satisfies: D ≤ 2 mm. This is beneficial to making the airflow formed when the fan impeller 4 rotates flow along the exhaust pipe 5, which is beneficial to discharging the gas in the cabinet 6 to the outside.
[0054] Refer to Figure 2 , in some embodiments, a plurality of fan impellers 4 are spaced apart on at least one rotating shaft 3. In this way, the multiple fan impellers 4 cooperate with each other, can generate a greater wind force, and are beneficial to discharging the gas in the cabinet 6 to the outside.
[0055] Refer to Figure 1 , there are a plurality of water-driven impellers 2, rotating shafts 3, exhaust pipes 5 and fan impellers 4. Each water-driven impeller 2 corresponds to one exhaust pipe 5, one rotating shaft 3 and at least one fan impeller 4. In this way, the combined action of each fan impeller 4 is beneficial to discharging the gas in the cabinet 6 to the outside.
[0056] In some embodiments, there are a plurality of water-driven impellers 2, rotating shafts 3, exhaust pipes 5 and fan impellers 4. Each water-driven impeller 2 corresponds to one exhaust pipe 5, one rotating shaft 3 and a plurality of fan impellers 4. In some embodiments, there are a plurality of water-driven impellers 2, rotating shafts 3, exhaust pipes 5 and fan impellers 4. Each water-driven impeller 2 corresponds to one exhaust pipe 5, one rotating shaft 3 and one fan impeller 4. In some embodiments, only one water-driven impeller 2, rotating shaft 3, exhaust pipe 5 and fan impeller 4 are provided.
[0057] Refer to Figure 1 , in some embodiments, in the exhaust device with a plurality of exhaust pipes 5, the lengths of the respective exhaust pipes 5 are the same. This is beneficial to arranging the air inlets 51 of the respective exhaust pipes 5 at the same height position in the cabinet 6, and is beneficial to discharging the gas at a specific height in the cabinet 6 to the outside.
[0058] In some embodiments, among the multiple exhaust devices provided in the exhaust pipe 5, the lengths of the respective exhaust pipes 5 are different. In this way, when making full use of the lengths of the respective exhaust pipes 5, the air inlet 51 of the exhaust pipe 5 with a shorter length can be arranged at the upper part of the space inside the cabinet 6, and the air inlet 51 of the exhaust pipe 5 with a longer length can be arranged at the lower part of the space inside the cabinet 6, so as to discharge the gas at different heights inside the cabinet 6 to the outside through the respective exhaust pipes 5.
[0059] Referring to Figure 1 and Figure 2 , the present application secondly provides a cooking system, which includes a cabinet 6, a water inlet pipe, a gas supply device, a faucet and the above-mentioned exhaust device. A receiving cavity 61 is provided inside the cabinet 6, and an avoidance hole 62 communicating with the receiving cavity 61 is provided on the cabinet 6. The water inlet pipe is partially located inside the receiving cavity 61, the gas supply device is partially located inside the receiving cavity 61, and the faucet is located outside the cabinet 6. The filter 1 is installed inside the receiving cavity 61. The flow channel 11 has a water inlet section 111 and a water outlet section 112. The water inlet section 111 supplies water to flow into the filter 1, and the water outlet section 112 supplies water to flow out of the filter 1. The water inlet pipe, the water inlet section 111, the water outlet section 112 and the faucet are connected in sequence. The exhaust pipe 5 passes through the avoidance hole 62. The exhaust pipe 5 has an air inlet 51 and an air outlet 52. The receiving cavity 61, the air inlet 51, the air outlet 52 and the outside are connected in sequence. After the faucet is opened, water flows through the flow channel 11, the impeller rotates around its own axis, thereby driving the fan impeller 4 to rotate. The fan impeller 4 drives the gas inside the cabinet 6 to be discharged to the outside through the exhaust pipe 5. In this way, the gas leaked inside the cabinet 6 can be discharged outside the cabinet 6, which is beneficial for the user to detect gas leakage and reduce the concentration of gas inside the cabinet 6, preventing safety accidents from occurring.
[0060] It can be understood that the filter 1 includes a filter element 12 for filtering water. Along the water flow path, the filter element 12 is located between the water inlet section 111 and the water outlet section 112, as Figure 1 and Figure 2 shown.
[0061] Referring to Figure 1 , there are multiple water-driven impellers 2, rotating shafts 3, exhaust pipes 5 and fan impellers 4. Each water-driven impeller 2 corresponds to an exhaust pipe 5, a rotating shaft 3 and at least one fan impeller 4. The air inlets 51 of the respective exhaust pipes 5 are all at the same height. In this way, it is beneficial to discharge the gas at a specific height inside the receiving cavity 61 to the outside.
[0062] Exemplarily, the gas supply device is a natural gas pipeline. If the natural gas pipeline ages or the connection loosens, slight natural gas leakage will occur. Since the density of natural gas is relatively small, the leaked natural gas accumulates in the upper part of the accommodation cavity 61. The air inlets 51 of each exhaust pipe 5 are all located at the same height in the upper part of the accommodation space, which is conducive to discharging the leaked natural gas to the outside. Preferably, the air inlets 51 of each exhaust pipe 5 are all located within the avoidance holes 62.
[0063] Exemplarily, the gas supply device is a gas cylinder. If the gas cylinder ages or the connection loosens, slight gas leakage will occur. Since the density of gas is relatively large, the leaked gas deposits in the lower part of the accommodation cavity 61. The air inlets 51 of each exhaust pipe 5 are all located at the same height in the lower part of the accommodation space, which is conducive to discharging the leaked gas to the outside.
[0064] In some embodiments, there are multiple water-driven impellers 2, rotating shafts 3, exhaust pipes 5 and fan impellers 4. Each water-driven impeller 2 corresponds to an exhaust pipe 5, a rotating shaft 3 and at least one fan impeller 4. The air inlets 51 of each exhaust pipe 5 are located at different heights, and the air inlets 51 of at least one exhaust pipe 5 are located within the accommodation cavity 61. In this way, it is conducive to discharging the gas at different heights in the accommodation cavity 61 to the outside.
[0065] In some embodiments, the gas supply device includes a natural gas pipeline and a gas stove. When natural gas leaks, the leaked natural gas accumulates in the upper part of the accommodation cavity 61. When gas leaks, the leaked gas deposits in the lower part of the accommodation cavity 61. Refer to Figure 2 , the cooking system includes multiple exhaust devices. Among them, at least one filter 1 is located in the upper part of the accommodation cavity 61, and at least one filter 1 is located in the lower part of the accommodation cavity 61. The air inlets 51 of at least one exhaust pipe 5 corresponding to the filter 1 located in the upper part of the accommodation cavity 61 are located within the avoidance holes 62, and the air inlets 51 of at least one exhaust pipe 5 corresponding to the filter 1 located in the lower part of the accommodation cavity 61 are located in the lower part of the accommodation cavity 61. In this way, whether natural gas leaks or gas leaks, after the faucet is turned on, the leaked gas can be discharged to the outside. Preferably, each filter 1 is connected in series (that is: the water inlet section 111 of the latter filter 1 is communicated with the water outlet section 112 of the previous filter 1), which is conducive to improving the purification degree of water. For example, one of the filters 1 is a pre-filter 1, and the pre-filter element 12 can adopt an activated carbon filter element 12 to remove sediment, chlorine and peculiar smell in the water. One of the filters 1 is a post-filter 1, and the post-filter 1 can adopt a cellulose filter element 12 to remove bacteria, viruses and other fine particles in the water.
[0066] Refer to Figure 1, there are multiple water-driven impellers 2, rotating shafts 3, exhaust pipes 5, and fan impellers 4. Each water-driven impeller 2 corresponds to one exhaust pipe 5, one rotating shaft 3, and at least one fan impeller 4. At least one water-driven impeller 2 is located in the water inlet section 111, and at least one water-driven impeller 2 is located in the water outlet section 112. The difference between the number of rotating shafts 3 located in the water inlet section 111 and the number of rotating shafts 3 located in the water outlet section 112 is less than or equal to 1. In this way, each rotating shaft 3 is relatively evenly distributed in the water inlet section 111 and the water outlet section 112, avoiding the excessive concentration of the rotating shafts 3 in the water inlet section 111 / water outlet section 112, which is beneficial to ensuring the structural strength of the filter 1 and avoiding the too small structural strength at a certain part of the filter 1.
[0067] Refer to Figure 2 , all parts on the outer side of the exhaust pipe 5 are in contact with the hole wall of the avoidance hole 62. In this way, the hole wall of the avoidance hole 62 plays a role in fixing the exhaust pipe 5, avoiding the need to additionally provide a structure for fixing the exhaust pipe 5.
[0068] In some embodiments, there are multiple avoidance holes 62 and exhaust pipes 5. Each avoidance hole 62 corresponds to one exhaust pipe 5. In other words, each avoidance hole 62 only passes through one exhaust pipe 5. In some embodiments, only one avoidance hole 62 is provided, and there are multiple exhaust pipes 5. In other words, multiple exhaust pipes 5 pass through the avoidance hole 62. In some embodiments, there are multiple avoidance holes 62 and exhaust pipes 5. Only one exhaust pipe 5 passes through some avoidance holes 62, and multiple exhaust pipes 5 pass through some avoidance holes 62.
[0069] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0070] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
