Description

Technical Field

[0001] The invention relates to a kitchen air conditioning system. Background Art

[0002] Cooking at the kitchen stove is a hard housework, especially in summer. The hot weather and the heat from the stove make the working environment in the kitchen very harsh. In order to solve the problem of high temperature in the kitchen, some people install fans or air conditioners in the kitchen. However, the cooling effect of the fan is average, and it will affect the normal operation of the gas stove and there are also safety hazards. Due to the special fume environment in the kitchen, after using the fan for a period of time, a large amount of putty is attached to the fan, which is difficult to clean and will also cause pollution to the kitchen environment. Installing air conditioning equipment in the kitchen has cost problems on the one hand and difficult cleaning problems on the other hand. After the fume is attached to the surface of the air conditioner heat exchanger, there is also a problem of reduced cooling effect. In addition, there is also a solution in the prior art to place the supply fan inside the range hood, but the structure is complicated and the air supply effect is not good, and it cannot stably and accurately supply air to the user's body. Therefore, in view of the problems of complex structure and poor air supply effect of using traditional kitchen cooling equipment in the kitchen, people have invented a range hood that can supply air. For example, the "range hood" disclosed in the Chinese invention patent application with application number CN201410078960.X (application publication number CN 104896545A) includes a housing and an air supply module arranged in the housing, wherein the air supply module further includes: an air inlet for sucking air from the surrounding environment; an air outlet channel connected to the air inlet, arranged in the housing and extending for a certain length to guide the airflow flowing therethrough; and an air supply fan, arranged in the air outlet channel, to cause the airflow to be sucked into the air outlet channel and blown out toward the front of the housing through the air outlet channel. Although the range hood can guide the airflow generated by the air supply fan to blow it toward the user at the stove in a predetermined direction, the air supply direction is stable and accurate, and the user's comfort is improved without affecting the normal operation of the stove, but the range hood cannot send outdoor fresh air into the kitchen through the range hood, and naturally does not provide a solution for dehumidifying the outdoor fresh air before sending it into the kitchen. In summary, there is a need to further improve the existing kitchen air conditioning system. Summary of the invention

[0018] The present invention is further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system of this embodiment includes a range hood 1 and a fresh air dehumidification module 2. Among them, a mutually isolated smoke exhaust channel 11 and an air outlet channel 12 are provided in the housing 10 of the range hood 1, and a range hood fan 13 is installed inside the housing 10. The smoke exhaust channel 11 is formed downstream of the air outlet of the range hood fan 13. The smoke exhaust channel 11 is externally connected to a smoke exhaust pipe 15, and the air outlet channel 12 is fluidically connected to the kitchen room. In this embodiment, the range hood fan 13 is a horizontally arranged centrifugal fan, and the smoke exhaust channel 11 and the air outlet channel 12 are distributed left and right to each other, and the air outlet channel 12 is located above the range hood fan 13, and the air outlet 122 of the air outlet channel 12 is arranged on the front of the housing 10 of the range hood 1, so that air can be discharged from the front of the range hood 1.

[0020] like Figure 3As shown, in this embodiment, an air supply fan 14 is installed in the air outlet channel 12. Under the action of the air supply fan 14, the fresh air dehumidified by the fresh air dehumidification module 2 enters the air outlet channel 12 through the air inlet 121 of the air outlet channel 12, and then blows into the kitchen room through the air outlet 122 on the front of the casing 10.

[0021] The fresh air dehumidification module 2 is installed above the kitchen ceiling. The fresh air dehumidification module 2 includes a solution dehumidification unit 21 and a solution regeneration unit 22. The solution dehumidification unit 21 of this embodiment is installed outside the housing 10 of the range hood 1, and the solution regeneration unit 22 is installed inside the housing 10. The outdoor fresh air can enter the air outlet channel 12 after being dehumidified by the solution dehumidification unit 21. The solution regeneration unit 22 is used to provide the solution dehumidification unit 21 with a regeneration solution 224 for dehumidification.

[0022] The principle of solution dehumidification fresh air is to use some solutions with good hygroscopicity, such as lithium bromide, lithium chloride, calcium chloride and other solutions to treat the air to be treated. On the dehumidification side, the water vapor partial pressure of the treated air is greater than the water vapor partial pressure of the concentrated solution. The pressure difference between the two is used to transfer moisture from the air to the solution, and the solution concentration becomes dilute. On the regeneration side, the process is the opposite, and the solution is regenerated. The water vapor partial pressure difference between the regenerated air and the solution is also used to continue to dehumidify the treated air with the regenerated solution, and the cycle is carried out.

[0023] The solution dehumidification unit 21 of this embodiment includes a dehumidification box body 211 and a dehumidification solution 212 installed in the dehumidification box body. A fresh air inlet pipe 213 and a fresh air outlet pipe 214 are installed on the dehumidification box body 211. One end of the fresh air inlet pipe 213 is connected to the outdoor fresh air, and the other end extends into the dehumidification solution 212. One end of the fresh air outlet pipe 214 is arranged on the air outlet of the dehumidification box body 211, and the other end is connected to the air inlet 121 of the air outlet channel 12.

[0024] The solution regeneration unit 22 of this embodiment includes a heat exchanger 221, a regeneration box 222, a heating pipe 223 and a regeneration solution 224. The heat exchanger 221 is installed in the smoke exhaust channel 11, the regeneration box 222 is arranged outside the smoke exhaust channel 11, the regeneration solution 224 is stored in the regeneration box 222, the heating pipe 223 is immersed in the regeneration solution 224 and is connected to the heat exchanger 221 through the heat exchange pipe 225, and the first pump body 226 is installed on the heat exchange pipe 225. The liquid outlet of the dehumidification box 211 is connected to the liquid inlet of the regeneration box 222 through the first pipeline 215, and the liquid outlet of the regeneration box 222 is connected to the liquid inlet of the dehumidification box 211 through the second pipeline 216, and the second pump body 217 is installed on the second pipeline 216.

[0025] In addition, the regeneration box 222 has a steam outlet 227, and the steam outlet 227 is connected to the smoke exhaust channel 11 through a steam channel 228, and a damper 229 is installed between the steam channel 228 and the smoke exhaust channel 11. When the steam outlet 227 does not generate steam, the damper 229 is closed under the action of its own weight, and the steam channel 228 is isolated from the smoke exhaust channel 11. When the steam outlet 227 generates steam, the damper 229 is opened under the action of the steam, and the steam channel 228 is connected to the smoke exhaust channel 11, and the steam enters the steam channel 228 and the smoke exhaust channel 11, and then is discharged through the smoke exhaust pipe 15.

[0026] Here’s how the system works:

[0027] After the range hood 1 is turned on, the outdoor fresh air passes through the dehumidification box 211 of the solution dehumidification unit 21, and the dehumidification solution 212 dehumidifies the fresh air. The diluted dehumidification solution 212 in the dehumidification box 211 enters the regeneration box 222. At the same time, the residual heat of the oil smoke in the exhaust passage 11 heats the heat exchanger 221. The heat exchanger 221 transfers the heat to the heating pipe 223 through the heat exchange medium in the heat exchange pipe 225. The heating pipe 223 then heats the regeneration solution 224 in the regeneration box 222. , so that the regeneration solution 244 is evaporated and the concentration is increased. Under the thrust of the steam, the air valve 229 is opened, and the evaporated water vapor is discharged into the smoke exhaust channel 11 through the steam channel 228 and discharged through the smoke exhaust pipe 15. The regeneration solution 224 with increased concentration is refluxed into the dehumidification box body 211 under the action of the second pump body 217. This cycle is repeated to continuously dehumidify the fresh air. The dehumidified fresh air enters the air outlet channel 12 and is then blown into the kitchen room through the air outlet 122 on the front of the casing 10.

[0028] In addition, the "fluid connection" referred to in the present invention refers to the spatial position relationship between two components or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber that allows fluid to flow through, or a combination of the above.
