Description

Technical Field

[0001] The present invention relates to an air - conditioner type range hood. Background Art

[0002] The kitchen is the main place where people cook, and the quality of the kitchen air environment directly affects the cooking experience. The kitchen is hot in summer and cold in winter, and there is a demand for cooling and heating. For this reason, people have invented various kitchen air - conditioners. In summer, the kitchen air is cooled, and in winter, warm air can be provided to the kitchen to improve the cooking comfort. The basic forms of existing kitchen air - conditioners are not much different from ordinary air - conditioners. Generally, there are two forms. One is the split - type of indoor and outdoor units, that is, the outdoor unit is located outdoors and the indoor unit is located indoors. Each of the indoor and outdoor units has a motor fan. The connection method of the split - type kitchen air - conditioner of indoor and outdoor units needs to be connected through pipelines, requires drilling holes in the wall, damages the decoration, and an outdoor unit needs to be hung outdoors, so the installation difficulty is relatively large and the structure is not compact enough. The other is the integrated structure of indoor and outdoor units. Although it can install both the second heat exchanger and the first heat exchanger of the air - conditioner indoors, a larger area of the wall needs to be damaged to install the exhaust heat pipe of the first heat exchanger, which not only increases the installation difficulty but also affects the indoor aesthetics.

[0003] Although there are products like air - conditioner range hoods on the market currently, that is, an air - conditioner component is added on the basis of the range hood platform, which can not only achieve all the functions of the range hood but also the functions of the air - conditioner. However, these air - conditioner range hoods often simply combine the indoor unit of the traditional air - conditioner with the traditional range hood, and the air - conditioner and the range hood work independently of each other and cannot be linked. In addition, the oil - fume discharge method of the existing air - conditioner range hoods is the same as that of conventional range hoods, that is, the oil - fume is discharged outdoors or into a common flue through an exhaust pipe. During the use of the air - conditioner range hood, the evaporator of the air - conditioner will generate condensate water, which is currently discharged outdoors through a water guide pipe and there is no other discharge method. In summary, it is necessary to further improve the existing air - conditioner range hoods. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an air - conditioner type range hood with a compact structure and capable of realizing internal oil - fume discharge in view of the above - mentioned current situation of the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows: This air-conditioning type range hood includes an air-conditioning component and a fume extraction component. The air-conditioning component includes a compressor, a first heat exchanger, and a second heat exchanger. The compressor, the first heat exchanger, and the second heat exchanger are connected and communicated through a refrigerant pipeline. The fume extraction component includes a casing. An oil fume extraction fan and an exhaust passage are provided in the casing. It is characterized in that: An air outlet passage is also provided in the casing. The first heat exchanger is arranged in the exhaust passage. The second heat exchanger is arranged in the air outlet passage. The air outlet of the exhaust passage is connected and communicated with the air inlet of the air outlet passage. The air outlet of the air outlet passage is arranged on the casing. An oil fume purification device is installed in at least one of the exhaust passage and the air outlet passage.

[0006] In order to make the air coming out of the air outlet of the air outlet passage cleaner, the oil fume purification device includes a first oil fume purification unit and a second oil fume purification unit. The first oil fume purification unit is arranged in the exhaust passage. And, along the flowing direction of the oil fume, the first oil fume purification unit is arranged upstream of the first heat exchanger. The second oil fume purification unit is arranged in the air outlet passage. And, along the flowing direction of the air, the second oil fume purification unit is arranged upstream of the second heat exchanger.

[0007] Preferably, the exhaust passage includes a first exhaust passage and a second exhaust passage. The first heat exchanger and the first oil fume purification unit are arranged in the first exhaust passage.

[0008] In order to open the inlet of one of the exhaust passages arbitrarily, a first valve piece is installed at the inlet of the first exhaust passage and the inlet of the second exhaust passage. By switching the first valve piece, one of the first exhaust passage and the second exhaust passage can be connected and communicated with the air outlet of the oil fume extraction fan.

[0009] In order to open the outlet of one of the exhaust passages arbitrarily, a second valve piece is installed at the outlet of the first exhaust passage and the outlet of the second exhaust passage. By switching the second valve piece, one of the first exhaust passage and the second exhaust passage can be connected and communicated with the air outlet passage.

[0010] In order to filter the oil fume entering the air outlet passage, a filter screen is installed in the air outlet passage. And, along the flowing direction of the air, the filter screen is arranged upstream of the second oil fume purification unit. The filter screen preferably adopts a coarse filter screen to filter large particles in the oil fume.

[0011] In order to enable the air outlet of the air outlet passage to discharge air smoothly, an air outlet fan is installed in the air outlet passage. And, along the flowing direction of the air, the air outlet fan is arranged downstream of the second heat exchanger.

[0012] The compressor can be installed in multiple different positions. Preferably, the compressor is installed inside the casing and is located outside the smoke exhaust passage and the air outlet passage.

[0013] Further preferably, the first heat exchanger is a condenser and the second heat exchanger is an evaporator.

[0014] Further preferably, a water receiving tray for collecting the condensed water generated by the evaporator is installed in the air outlet passage. The condensed water in the water receiving tray is discharged outside the range hood through a drain pipe or sprayed onto the first heat exchanger through a spraying device. In this way, the condensed water can be discharged, or used to cool the first heat exchanger, improving the heat exchange efficiency of the first heat exchanger.

[0015] Further preferably, both the smoke exhaust passage and the air outlet passage are located above the smoke exhaust fan, and the smoke exhaust passage and the air outlet passage are distributed adjacent to each other left and right.

[0016] As a preference for any of the above solutions, a throttling device is installed on the refrigerant pipeline between the first heat exchanger and the second heat exchanger.

[0017] Compared with the prior art, the advantages of the present invention are as follows: The two heat exchangers of the air conditioning assembly of the air conditioner type range hood are respectively arranged in the smoke exhaust passage and the air outlet passage, with a compact structure. The oil fume discharged from the smoke exhaust passage can be discharged from the air outlet of the air outlet passage after being purified by the oil fume purification device. Since the air outlet of the air outlet passage is arranged on the casing of the range hood, the oil fume can be discharged indoors, and the oil fume exchanges heat with the heat exchanger in the air outlet passage when passing through the air outlet passage, so that cold air or hot air can be blown out from the air outlet of the air outlet passage as needed, enhancing the user's cooking experience.

[0021] The present invention will be further described in detail below in conjunction with the embodiments of the drawings.

[0022] As shown in Figure 1 and Figure 2As shown in the figure, the air-conditioning type range hood of this embodiment includes an air-conditioning component and a range hood component. The air-conditioning component includes a compressor 11, a first heat exchanger 12, and a second heat exchanger 13. The compressor 11, the first heat exchanger 12, and the second heat exchanger 13 are connected through a refrigerant pipeline 14. A throttling component 15 is installed on the refrigerant pipeline 14 between the first heat exchanger 12 and the second heat exchanger 13. A secondary refrigerant flows through the refrigerant pipeline 14. Common secondary refrigerants can be water, ethylene glycol, glycerol, and so on. The specific working principle of the air-conditioning component is the same as that of existing air conditioners and will not be elaborated here.

[0023] The range hood component of this embodiment has a casing 20. Inside the casing 20, there are installed a range hood fan 21, a smoke exhaust passage 22, and an air outlet passage 23. Figure 1 Taking the direction indicated by arrow A as right, the smoke exhaust passage 22 and the air outlet passage 23 are arranged above the range hood fan 21. Moreover, the air outlet passage 23 is located on the right side of the smoke exhaust passage 22. The air inlet of the air outlet passage 23 is connected to the air outlet of the smoke exhaust passage 22. In this embodiment, the air outlet of the air outlet passage 23 is arranged at the top of the casing 20. In addition, the air outlet of the air outlet passage 23 can also be arranged on the front or side of the casing 20.

[0024] The compressor 11 is installed inside the casing 20. Specifically, the compressor 11 is located on the right side of the range hood fan 21 and below the air outlet passage 23.

[0025] The smoke exhaust passage 22 of this embodiment includes a first smoke exhaust passage 221 and a second smoke exhaust passage 222. A first valve plate 41 is installed at the inlet of the first smoke exhaust passage 221 and the inlet of the second smoke exhaust passage 222. By switching the first valve plate 41, one of the first smoke exhaust passage 221 and the second smoke exhaust passage 222 can be connected to the air outlet of the range hood fan 21. A second valve plate 42 is installed at the outlet of the first smoke exhaust passage 221 and the outlet of the second smoke exhaust passage 222. By switching the second valve plate 42, one of the first smoke exhaust passage 221 and the second smoke exhaust passage 222 can be connected to the air outlet passage 23.

[0026] In the first smoke exhaust passage 221, a first oil fume purification unit 31 and a first heat exchanger 12 are installed. And, along the oil fume flow direction, the first oil fume purification unit 31 is located upstream of the first heat exchanger 12 to prevent the oil fume from polluting the first heat exchanger 12. In the air outlet passage 23, a filter screen 5, a second oil fume purification unit 32, a second heat exchanger 13 and an air outlet fan 24 are installed. And, the filter screen 5, the second oil fume purification unit 32, the second heat exchanger 13 and the air outlet fan 24 are distributed in sequence along the air flow direction. In this embodiment, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator. The filter screen 5 preferably can adopt a coarse filter screen, and the first oil fume purification unit 31 and the second oil fume purification unit 32 preferably can adopt various electrostatic purification devices in the prior art.

[0027] In addition, a water receiving tray 6 is installed in the air outlet passage 23, and the water receiving tray 6 is located below the second heat exchanger 13, i.e., the evaporator. When the air conditioner works, the condensed water generated by the evaporator flows into the water receiving tray 6, and the water in the water receiving tray 6 is discharged through a drain pipe 7. As Figure 3 shown, a water pump 8 is installed on the drain pipe 7, and a water pipe 9 is installed in the kitchen wall body. Under the action of the water pump 8, the condensed water is discharged into the water pipe 9 through the drain pipe 7. In addition, the condensed water can also be utilized. For example, the condensed water can be used to spray and cool the first heat exchanger 12 in the first smoke exhaust passage 221 to improve its heat exchange effect.

[0028] Taking the refrigeration mode as an example, the working principle of this air conditioner type range hood is as follows:

[0029] As Figure 1 shown, both the range hood and the air conditioner are turned on. The first valve plate 41 deflects to the left, and the second valve plate 42 rotates upward. At this time, the first smoke exhaust passage 221 is opened, the second smoke exhaust passage 222 is closed, and the outlet of the first smoke exhaust passage 221 is communicated with the air outlet passage 23. The oil fume first enters the first smoke exhaust passage 221, and the first oil fume purification unit 31 purifies the oil fume. Then, the purified oil fume enters the air outlet passage 23, and the filter screen 5 and the second oil fume purification unit 32 further purify the oil fume. The purified air is cooled after flowing through the second heat exchanger 13, i.e., the evaporator, and finally is blown out from the air outlet of the air outlet passage 23 under the action of the air outlet fan 24 to cool the kitchen air and improve the user's cooking experience.

[0030] As Figure 2As shown, when only the range hood is turned on, the first valve piece 41 deflects to the right and the second valve piece 42 rotates downward. At this time, the first smoke exhaust passage 221 is closed and the second smoke exhaust passage 222 is opened. The outlet of the second smoke exhaust passage 222 is communicated with the air outlet passage 23. The oil fume first enters the second smoke exhaust passage 222, then enters the air outlet passage 23 and is further purified by the filter screen 5 and the second oil fume purification unit 32, and finally is blown out from the air outlet of the air outlet passage 23 under the action of the air outlet fan 24.

[0031] In the heating mode, the first heat exchanger 12 is an evaporator and the second heat exchanger 13 is a condenser. Warm air is blown out from the air outlet of the air outlet passage 23. The switching mode of the smoke exhaust passage 22 is the same as that in the cooling mode and will not be described in detail here.

[0032] As described above, the air conditioner type range hood of this embodiment realizes the internal discharge of oil fume, thus solving the problem of outdoor environmental pollution that may be caused by the external discharge of oil fume.
