Description

Technical Field

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

[0002] The kitchen is the main place for people to 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 need for cooling and heating. For this reason, people have invented various kitchen air conditioners to cool the kitchen air in summer and provide warm air to the kitchen in winter to improve cooking comfort.

[0003] The basic form of the existing kitchen air conditioner is not much different from that of ordinary air conditioners. Generally, there are two forms. One is the split type of internal and external units, that is, the external unit is located outdoors and the internal unit is located indoors. The internal and external units each have a motor fan. The connection method of the kitchen air conditioner with split internal and external units needs to be connected through pipes, and holes need to be opened on the wall, which destroys the decoration. An external unit needs to be hung outdoors, which is difficult to install and the structure is not compact enough. The other is an integrated structure of the internal and external units. Although it can install the second heat exchanger and the first heat exchanger of the air conditioner indoors, it is necessary to destroy a larger area of ​​the wall to install the heat exhaust pipe of the first heat exchanger, which not only increases the difficulty of installation, but also affects the beauty of the room. In addition, due to the limited space in the kitchen, the volume of the kitchen air conditioner cannot be too large. Therefore, there are major problems in the heat dissipation of the kitchen air conditioner. If the kitchen air conditioner cannot dissipate heat in time during use, the energy efficiency of the air conditioner will be greatly reduced. However, the existing kitchen air conditioner and the range hood work independently of each other, and the two cannot be linked. The heat generated by the kitchen air conditioner cannot be discharged to the outside through the fan of the range hood. Therefore, how to discharge the heat generated by the kitchen air conditioner through the range hood has become a problem that people need to solve urgently.

[0004] Although there are products such as air-conditioning hoods on the market, that is, air-conditioning components are added to the range hood platform, which can realize all the functions of the range hood and the functions of the air conditioner at the same time. However, these air-conditioning hoods often simply merge the functions of the traditional air-conditioning indoor unit and the traditional range hood, and the air-conditioning outdoor unit still needs to be installed separately outdoors. This type of air-conditioning range hood is not integrated enough, and the installation is more cumbersome. Moreover, the pipe and line connection between the indoor and outdoor units of the air conditioner will also damage the wall. In addition, during the use of the air-conditioning hood, the evaporator of the air conditioner will produce condensed water, which is currently discharged to the outside through the water pipe, and there is no other discharge method.

[0030] The present invention is further described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figures 1 to 5 As shown, the kitchen air conditioning system of this embodiment includes an air conditioning component and a fume extraction 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 device 15 is installed on the refrigerant pipeline 14 between the first heat exchanger 12 and the second heat exchanger 13. The specific working principle of the air conditioning component 1 is the same as that of the existing air conditioner, and will not be described in detail here.

[0033] The oil fume extraction assembly of this embodiment has a housing 20, and an oil fume extraction fan 21 is installed at the lower part of the housing 20. The oil fume extraction fan 21 of this embodiment is a horizontally arranged centrifugal fan. The upper part of the housing 20 is provided with a mutually isolated smoke exhaust channel 22 and an air outlet channel 23. Along the oil fume flow direction, the smoke exhaust channel 22 is arranged downstream of the air outlet of the oil fume extraction fan 21. Figure 1 The direction indicated by the middle arrow A is right, and the air outlet channel 23 is located on the right side of the smoke exhaust channel 22, and the air outlet channel 23 is located directly above the range fumes suction fan 21. The compressor 11 of this embodiment is arranged at the lower part of the casing 20 and integrated thereon.

[0034] The first heat exchanger 12 and the electrostatic purification device 5 are installed in the smoke exhaust channel 22 , and the electrostatic purification device 5 is arranged upstream of the first heat exchanger 12 along the flow direction of the oil smoke, so as to prevent the oil smoke from polluting the first heat exchanger 12 .

[0035] The housing 20 is provided with an air inlet 24 and an air outlet 25, and an air outlet channel 23 is formed between the air inlet 24 and the air outlet 25. An air outlet fan 26, a filter 27 and a second heat exchanger 13 are installed in the air outlet channel 23, and the filter 27, the second heat exchanger 13 and the air outlet fan 26 are arranged in sequence along the path of air flow. The air inlet 24 can be fluidly connected with the interior of the kitchen, that is, indoor air intake is realized, and it can also be fluidly connected with the exterior of the kitchen, that is, outdoor fresh air intake is realized; the air outlet 25 of this embodiment is arranged on the front of the housing 20, so that air can be directly discharged from the front of the housing 20, and the air outlet can also be arranged on the top of the housing 20, and connected with the air outlet hole on the kitchen ceiling through the air duct to realize ceiling air outlet.

[0036] A condensed water collection device is provided in the housing 20 to collect condensed water generated when the system is working. The condensed water collection device of this embodiment adopts a water receiving pan provided in the air outlet channel 23, and the water receiving pan specifically includes a first water receiving pan 31 and a second water receiving pan 32, wherein the first water receiving pan 31 is located at the lower part of the air outlet channel 23 and is provided below the second heat exchanger 13, and the second water receiving pan 32 is located at the upper part of the air outlet channel 23, and the first water receiving pan 31 and the second water receiving pan 32 are connected through a water pipe 33, and a water pump 34 is installed on the water pipe 33, and a groove 30 is provided at the bottom of the second water receiving pan 32. In addition, the first water receiving pan can also be arranged above the second water receiving pan, in which case, there is no need to install a water pump on the water pipe, and the condensed water can flow from the first water receiving pan to the second water receiving pan by gravity.

[0037] A heat transfer element is installed between the smoke exhaust channel 22 and the air outlet channel 23. The heat transfer element of this embodiment is a heat pipe 4. The evaporation section 41 of the heat pipe 4 extends into the smoke exhaust channel 22. In this embodiment, along the flow direction of the oil smoke, the evaporation section 41 of the heat pipe 4 is arranged downstream of the first heat exchanger 12, and the condensation section 42 of the heat pipe 4 is arranged in the groove 30 of the second water receiving tray 32. In addition, the lower part of the heat pipe 4 is arranged in the groove 30, and the upper part of the heat pipe 4 is exposed in the groove 30. In addition, the position of the condensation section 42 is higher than the evaporation section 41. After the medium in the heat pipe 4 condenses and releases heat to become liquid, it flows back from the condensation section 42 to the evaporation section 41 by gravity. In addition, the evaporation section 41 of the heat pipe 4 can also be arranged upstream of the first heat exchanger 12.

[0038] The working principle of the kitchen air conditioning system is as follows:

[0039] In the cooling mode, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator. The oil smoke is discharged through the exhaust channel 22, and the oil smoke airflow passing over the surface of the first heat exchanger 12 can cool down and dissipate the heat of the first heat exchanger 12, reduce the temperature of the refrigerant flowing through the first heat exchanger 12, thereby improving the heat exchange effect of the first heat exchanger 12, and further improving the energy efficiency of the air conditioner. At the same time, under the action of the air outlet fan 26, cold air is sent into the kitchen room from the air outlet 25. At the same time, the condensed water generated by the second heat exchanger 13 enters the condensed water collection device, and the internal medium of the heat pipe 4 condenses in the condensation section 42 to emit heat, thereby evaporating the condensed water.

[0040] In the heating mode, the first heat exchanger 12 is an evaporator, and the second heat exchanger 13 is a condenser. The cold energy of the first heat exchanger 12 is discharged with the oil smoke, and warm air is blown out from the air outlet 25, and no condensed water is generated in the air outlet channel 23.

[0041] In addition, the oil fume extraction component of the present invention is not limited to the structure of installing the oil fume extraction fan inside the casing. The oil fume extraction component can also adopt a non-powered structure, that is, the oil fume extraction component only retains the smoke collecting shell, and the oil fume fan is placed outside the casing. For example, the oil fume extraction fan can be installed on the top of the public flue of the building.

[0042] Embodiment 2:

[0043] like Figure 6 and Figure 7 As shown, in the kitchen air conditioning system of this embodiment, the evaporation section 41 of the heat pipe 4 is close to the first heat exchanger 12. In the cooling mode, the heat in the smoke exhaust channel 22 and the heat of the first heat exchanger 12 are fully transferred to the evaporation section 41 of the heat pipe 4, and the internal medium of the heat pipe 4 condenses in the condensation section 42 to emit heat, thereby heating and evaporating the condensed water. The rest of the structure and working principle of this embodiment can refer to the first embodiment, and will not be described in detail here.

[0044] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), 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 allowing fluid to flow through, or a combination of the above.
