Description

Technical Field

[0001] The utility model belongs to the field of range hoods, and in particular relates to a flat range hood that can be used in a gas leakage environment. Background Art

[0002] A range hood is a household appliance that exhausts cooking fumes and purifies the kitchen environment. When it is working, the main motor drives the fan to rotate, generating air flow. The airflow is guided by the body components, creating a negative pressure area at the air inlet to absorb the fumes and exhaust them to the outside through the air outlet. At present, traditional range hoods on the market are only used to exhaust kitchen fumes. They are prone to static electricity or sparks during startup, operation, and shutdown. When a natural gas leak occurs in the kitchen, the natural gas in the environment needs to be exhausted outdoors as soon as possible. At this time, using a traditional range hood is likely to cause a natural gas explosion.

[0003] Therefore, a novel range hood is needed to overcome the technical defects currently existing therein. Utility Model Content

[0004] The problem that the utility model aims to solve is to provide a flat-plate range hood that can be used in a gas leakage environment. The range hood adopts an explosion-proof design, and will not generate electric arcs, sparks or high-temperature points that ignite natural gas when in use. It can also effectively isolate the impact generated by the explosion. At the same time, the upper and lower double air inlet design can achieve faster and better gas suction effects, and the volute assembly is networked with the indoor gas leakage alarm to promptly discharge the leaked natural gas in the room.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model provides a flat range hood that can be used in a gas leakage environment, comprising a body and a chassis connected to the upper part of the body, and further comprising:

[0007] The cross-sectional shape of the machine body is an inverted L-shape;

[0008] A return groove is provided on the top of the inner concave surface of the body close to the surface of the downwardly extending portion of the body;

[0009] An upper air inlet is arranged on the surface of the reflux groove away from the downwardly extending portion of the body;

[0010] An explosion-proof LED lamp is arranged on the surface of the top of the inner concave surface of the machine body away from the downward extending portion of the machine body;

[0011] An oil cup is provided at the bottom of the downwardly extending portion of the machine body;

[0012] A lower air inlet is provided on one side of the downwardly extending portion of the concave surface of the body close to the oil cup;

[0013] An explosion-proof volute assembly is provided inside the chassis;

[0014] The body and the chassis include explosion-proof housings;

[0015] The explosion-proof volute assembly is networked and connected to an indoor gas leakage alarm.

[0016] Furthermore, the material of the explosion-proof housing includes 0.8 mm steel plate sprayed with an anti-static coating.

[0017] Furthermore, the explosion-proof volute assembly includes a volute, a wind wheel disposed in the volute, and an explosion-proof motor whose output end is connected to the wind wheel;

[0018] Among them, the models of the explosion-proof motor include YBF3-56#.

[0019] Furthermore, the explosion-proof volute assembly is connected to the indoor gas leakage alarm through a wireless network.

[0020] The utility model has the following beneficial effects:

[0021] (1) Optimize the suction and exhaust system. The flue gas that cannot be sucked in by the lower air inlet will be sucked in through the upper air inlet, which has the function of secondary flue gas suction and greatly improves the suction efficiency of oil smoke and natural gas.

[0022] (2) By using explosion-proof LED lamps and explosion-proof volute components, no arcs, sparks or high-temperature points that may ignite natural gas will be generated when the range hood is started, operated or shut down. Even if the range hood is used to exhaust natural gas in a gas leakage environment, there is no possibility of fire or explosion.

[0023] (3) The explosion-proof shell design can effectively isolate the impact caused by the explosion. Even if an explosion occurs, the range hood can still operate normally and discharge harmful gases in the environment.

[0024] (4) Networked with gas leak alarms to monitor natural gas concentration in real time, enabling timely response and measures to effectively prevent fires or explosions caused by excessive indoor natural gas concentrations.

[0025] (5) It has wide applicability. In addition to being used in home kitchens, it can also be widely used in industrial environments or other places where there may be a risk of gas leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1

[0033] A flat range hood that can be used in a gas leakage environment comprises a body 1 and a case 2 connected to the upper part of the body 1, and further comprises:

[0034] The cross-sectional shape of the machine body 1 is an inverted L-shape;

[0035] A reflow groove 8 is provided on the top of the inner concave surface of the body 1 and the surface of the downwardly extending portion of the body;

[0036] An upper air inlet 4 is provided on the surface of the downwardly extending portion of the return groove 8 away from the machine body 1;

[0037] An explosion-proof LED lamp 3 is provided on the top of the inner concave surface of the body 1 away from the surface of the downwardly extending portion of the body 1;

[0038] An oil cup 6 is provided at the bottom of the downwardly extending portion of the machine body 1;

[0039] A lower air inlet 5 is provided on one side of the downwardly extending portion of the concave surface of the body 1 close to the oil cup 6;

[0040] An explosion-proof volute assembly 7 is provided inside the chassis 2;

[0041] The body 1 and the chassis 2 include explosion-proof housings;

[0042] The explosion-proof volute assembly 7 is networked with the indoor gas leakage alarm.

[0043] In the above embodiment, the upper air inlet 4 can inhale and discharge the smoke missed by the lower air inlet 5 to keep the kitchen air fresh; the use of explosion-proof LED lamps 3 and explosion-proof volute components 7 can prevent the range hood from generating arcs, sparks or igniting high-temperature points of natural gas when starting, running and shutting down, greatly reducing the possibility of fire or explosion caused by using the range hood when natural gas leaks; the use of explosion-proof casing can effectively resist the impact of the explosion, isolate the explosion outside the range hood, prevent the explosion impact from damaging the internal components of the range hood, ensure that the range hood still has a complete structure and function when a fire or explosion occurs, and can discharge toxic gases in the environment in time; the concentration of natural gas in the air is monitored in real time by an indoor gas leak alarm. When the natural gas concentration reaches the alarm value, the range hood starts immediately to discharge the natural gas into the room.

[0044] Example 2

[0045] The present invention is further improved based on Example 1 in that:

[0046] The material of the explosion-proof casing is 0.8mm steel plate sprayed with anti-static coating. The 0.8mm steel plate sprayed with anti-static coating has excellent anti-static ability, which can effectively conduct static electricity on the surface of the steel plate to avoid fire or explosion caused by static electricity when natural gas leaks. At the same time, it also has excellent anti-corrosion performance, which can prevent the range hood from being corroded by oil smoke, seasonings and other substances during use, ensuring that the equipment still has good explosion-proof ability after long-term use.

[0047] Example 3

[0048] The present invention is further improved based on Example 2 in that:

[0049] The explosion-proof volute assembly 7 includes a volute 9, a wind wheel 10 arranged in the volute 9, and an explosion-proof motor 11 whose output end is connected to the wind wheel 10, wherein the explosion-proof motor is preferably model YBF3-56#, and the volute 9, the wind wheel 10 and the explosion-proof motor 11 form a large suction duct system with the upper air inlet 4 and the lower air inlet 5, which can discharge the oil smoke or leaked natural gas in the kitchen more quickly.

[0050] In some more preferred embodiments,

[0051] Example 4

[0052] The present invention is further improved based on Example 3 in that:

[0053] The explosion-proof volute assembly 7 is connected to the indoor gas leakage alarm through a wireless network, so the installation position of the range hood will not be restricted.

[0054] In some more preferred schemes, the range hood provided by the utility model can be used in conjunction with the gas safety center monitoring system, which can not only monitor the natural gas concentration in the air in real time and automatically start the range hood to exhaust natural gas after a natural gas leak, but also record the natural gas leak information into the system and feed back the leakage information to the user or the safety monitoring center to ensure that the problem of natural gas leakage on site can be resolved in a timely manner.

[0055] The flat-panel range hood provided by the utility model can be used in a gas leakage environment. It not only has an efficient suction and exhaust system, effective explosion-proof capability, and excellent corrosion and impact resistance, but can also monitor the natural gas concentration in the environment and respond promptly when a gas leak occurs to exhaust the natural gas in the environment. The flat-panel range hood is not only suitable for home kitchens, but also can be used in industrial environments or other places where there may be a risk of natural gas leakage.

[0056] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
