Description

Technical Field

[0001] The utility model relates to a range hood, in particular to an air-conditioning type range hood. Background Art

[0002] In order to improve the user's cooking experience, people have invented various air-conditioning hoods to provide cold air to the kitchen in summer and warm air in winter. The air-conditioning hood integrates the air-conditioning component with the range hood, and an air-conditioning outlet is opened on the shell of the range hood. The air-conditioning hood can work in multiple different modes. As long as the air-conditioning mode is turned on, the air-conditioning outlet will blow out cold air or hot air, which can be blown directly to the cook or to the kitchen, thereby effectively improving the cook's cooking experience. For the air-conditioning hood working in the cooling mode, in order to improve the energy efficiency of the air conditioner, people have designed a structure in which the condenser is installed in the exhaust channel. The exhaust channel also constitutes a heat dissipation channel, that is, the heat of the condenser is taken away by the oil smoke, and the condenser is dissipated to improve its heat exchange effect. Since the condenser temperature is high, if it is only dissipated by the oil smoke airflow, the heat dissipation effect is not good. For this reason, people have invented a structure that uses air-conditioning condensed water to dissipate heat from the condenser, that is, the air-conditioning condensed water is transported to the surface of the condenser, and the condensed water is used to reduce the surface temperature of the condenser, thereby improving its heat exchange effect.

[0003] For example, the Chinese utility model patent with patent number CN202320196584.9 (publication number CN219550622U) discloses a refrigeration-type range hood, which includes an upper box and a lower cavity. An air conditioner module is provided outside the upper box. The upper box is divided into a smoke exhaust cavity and a heat dissipation cavity. A smoke exhaust fan is installed in the smoke exhaust cavity. The heat dissipation cavity is connected to the smoke exhaust cavity through a heat dissipation outlet. A condenser is installed in the heat dissipation cavity. The condensed water condensed on the evaporator can drip onto or be transported to the condenser. A heat dissipation fan and a water pump are installed below the condenser. The heat dissipation fan and the water pump are coaxially arranged and rotated under the drive of the same motor. The condensed water that has not been consumed by the condenser is pumped back to the condenser through the water pump or discharged to the outside of the upper box. The condensed water that has not been consumed by the condenser in the refrigeration range hood can be pumped back to the condenser through the water pump, and continue to rely on the high temperature of the condenser surface for heat exchange and evaporation consumption, or it can be discharged to the outside of the upper box through the water pump.

[0004] This patent requires the installation of a water receiving pan, condensate pipes, etc., involving many components and high costs. Although this patent has two-pronged approach to the condensate that is not consumed by the condenser to prevent the condensate from accumulating in the machine body, one of the solutions requires the installation of a water pump to pump the unconsumed condensate back to the condenser, involving many components and requiring pipe connections between the water pump and the water distributor, resulting in complex and messy pipes. Another solution is to directly discharge the water from the pump to the outside of the upper box body, but if the external discharge position is unreasonable, it is easy to cause social problems, and the external discharge of condensate will cause long-term erosion of the user's external wall and dripping in the external environment. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an air-conditioning type range hood capable of processing condensed water without setting too many components in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: an air-conditioning type range hood, including a body and an air-conditioning system arranged on the body, the air-conditioning system including an evaporator, a compressor and a condenser, the compressor, condenser and evaporator are connected by a refrigerant pipeline, and is characterized in that a water absorption plate is provided on the body, and the water absorption plate is located on the path where condensed water condensed on the evaporator drips or is transported.

[0007] In order to facilitate the transportation of condensed water condensed by the evaporator to the water absorption plate, an inner machine shell is provided on the machine body, the evaporator is installed in the inner machine shell, a condensed water outlet is provided at the bottom of the inner machine shell, and a water pipe for transporting condensed water is provided at the condensed water outlet.

[0008] Preferably, the end of the water delivery pipe is located above the water absorption plate and faces the water absorption plate to ensure that the water in the water delivery pipe flows onto the water absorption plate.

[0009] In order to make the water pipe evenly distributed on the water absorption plate and prevent the local water absorption load of the water absorption plate from being too large, which will cause condensed water to drip, the end of the water pipe is connected to a strip-shaped water distributor. The water distributor is hollow inside and is fluidically connected to the water pipe. The bottom of the water distributor has a water outlet, and the water distributor extends along the length direction of the water absorption plate.

[0010] Preferably, the local section of the water pipe is spirally formed into a spiral section, and the spiral section is wound around the exhaust pipe connected to the compressor exhaust port through which the refrigerant flows. The exhaust pipe and the water pipe together constitute the condenser, and the compressor, the exhaust pipe and the evaporator are connected through the refrigerant pipeline. In this way, the electric energy of the compressor is converted into the internal energy of the refrigerant, and the heat is exchanged between the spiral section and the exhaust pipe, so that the internal energy of the refrigerant is transferred to the condensed water, the condensed water is preheated, and the efficiency of subsequent evaporation of the condensed water is improved; at the same time, the condensed water is used to cool down the exhaust pipe of the compressor in advance, and under the same conditions, the heat dissipation pressure of the condenser can be reduced.

[0011] Because the condenser needs to be cooled to ensure the cooling effect of the refrigeration system formed by the evaporator, the compressor and the condenser, the machine body includes an upper box body and a lower cavity provided at the bottom of the upper box body, the upper box body is divided into a smoke exhaust cavity and a heat dissipation cavity, the lower cavity and the smoke exhaust cavity are fluidically connected, a fume suction fan is installed in the smoke exhaust cavity, the heat dissipation cavity has a heat dissipation air inlet and a heat dissipation air outlet, the heat dissipation air inlet is connected to the outside, the heat dissipation cavity is connected to the smoke exhaust cavity through the heat dissipation air outlet, and the compressor and the condenser are arranged in the heat dissipation cavity. In this way, the heat dissipation fan blows the outside cold air to the condenser for heat dissipation, and then the airflow blowing through the condenser is discharged from the smoke exhaust cavity along with the oil smoke.

[0012] In order to make the air flow flow from the heat dissipation air inlet to the heat dissipation air outlet, the heat dissipation cavity is provided with an air flow driving member for driving the air flow from the heat dissipation air inlet to the heat dissipation air outlet.

[0013] In the above scheme, the air flow driving component is a heat dissipation fan, the air inlet of the heat dissipation fan is fluidly connected with the heat dissipation air inlet, and the air outlet of the heat dissipation fan is fluidly connected with the heat dissipation air outlet.

[0014] In order to reuse the water absorption plate, the water absorption plate is located upstream of the air inlet of the heat dissipation fan along the air flow path, so that the air flow driven by the heat dissipation fan will flow through the water absorption plate, and the air flow will cause the condensed water to evaporate, so that the water absorption plate can be reused.

[0015] In order to make the water absorption plate reusable, the water absorption plate is located downstream of the air outlet of the heat dissipation fan along the air flow path, so that the air flow driven by the heat dissipation fan will flow through the water absorption plate, and the air flow will cause the condensed water to evaporate and be discharged from the smoke exhaust cavity along with the oil smoke, so that the water absorption plate can be reused.

[0016] Compared with the prior art, the advantages of the utility model are as follows: the utility model can absorb the condensed water condensed on the evaporator by setting a water absorption plate, thereby avoiding the social or environmental problems caused by the discharge of condensed water; and compared with the solution of pumping water to the top of the condenser through a water pump, the structure of the present application is simple, involves fewer components and has low cost.

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

[0022] Example 1

[0023] like Figure 1 As shown, the air-conditioning type range hood of the preferred embodiment includes a body 1, an inner machine shell 2 is provided on the body 1, an evaporator 3 is provided outside the body 1, and the evaporator 3 is installed in the inner machine shell 2. A compressor 4 and a condenser 5 are also provided on the body 1. The compressor 4, the condenser 5 and the evaporator 3 are connected by a refrigerant pipeline, and the three together constitute an air-conditioning system. This is the prior art and will not be repeated here. The working principles of the compressor 4, the condenser 5 and the evaporator 3 are the same as those of the existing air conditioner.

[0024] A water absorption plate 6 is provided on the body 1, and the water absorption plate 6 is located on the path where the condensed water condensed on the evaporator 3 drips or is transported. The water absorption plate 6 can be made of materials such as diatom mud, volcanic stone, zeolite, etc., and has a certain structural strength, can absorb water, and has a very large internal and external surface area ratio.

[0025] In this embodiment, a condensate outlet 21 is provided at the bottom of the inner casing 2, and a water pipe 22 for conveying condensate is provided at the condensate outlet 21. The end of the water pipe 22 is located above the water absorption plate 6 and faces the water absorption plate 6 to ensure that the water in the water pipe 22 flows to the water absorption plate 6.

[0026] The end of the water pipe 22 may be connected to a strip-shaped water distributor (not shown in the figure), the interior of the water distributor is hollow and in fluid communication with the water pipe 22, the bottom of the water distributor has a water outlet, and the water distributor extends along the length direction of the water absorption plate 6, so that the water pipe 22 is evenly distributed on the water absorption plate 6, to prevent the water absorption plate 6 from having an excessive local water absorption load, resulting in condensed water dripping. The structure of the water distributor can refer to the structure of the strip-shaped spray arm of the dishwasher.

[0027] Example 2

[0028] The difference between this embodiment and embodiment 1 is that the structure of the water delivery pipe 22 is different.

[0029] like Figure 2 , 3 As shown, a local section of the water pipe 22 is spirally formed into a spiral section 221, and the spiral section 221 is wound around the exhaust pipe 41 connected to the exhaust port of the compressor 4. The exhaust pipe 41 is used for the flow of refrigerant. The exhaust pipe 41 and the water pipe 22 together constitute the condenser 5. The compressor 4, the exhaust pipe 41 and the evaporator 3 are connected through the refrigerant pipeline. In this way, the electric energy of the compressor 4 is converted into the internal energy of the refrigerant, and the heat is exchanged between the spiral section 221 and the exhaust pipe 41, and the internal energy of the refrigerant is transferred to the condensed water, and the condensed water is preheated to improve the efficiency of the subsequent evaporation of the condensed water; at the same time, the condensed water is used to cool down the exhaust pipe 41 of the compressor 4 in advance. Under the same conditions, the heat dissipation pressure of the condenser 5 can be reduced.

[0030] The body 1 includes an upper box body 11 and a lower cavity body 12 arranged at the bottom of the upper box body 11. The upper box body 11 is divided into a smoke exhaust chamber 111 and a heat dissipation chamber 112. The lower cavity body 12 and the smoke exhaust chamber 111 are fluidically connected. A fume suction fan 113 is installed in the smoke exhaust chamber 111. The heat dissipation chamber 112 has a heat dissipation air inlet and a heat dissipation air outlet 115. The heat dissipation air inlet is connected to the outside. The heat dissipation chamber 112 is connected to the smoke exhaust chamber 111 through the heat dissipation air outlet 115. The compressor 4 and the condenser 5 are arranged in the heat dissipation chamber 112.

[0031] An airflow driving component 7 is provided in the heat dissipation cavity 112 for driving the air flow from the heat dissipation air inlet to the heat dissipation air outlet 115. The airflow driving component 7 is a heat dissipation fan. The air inlet of the heat dissipation fan is fluidically connected to the heat dissipation air inlet, and the air outlet of the heat dissipation fan is fluidically connected to the heat dissipation air outlet 115.

[0032] In this way, the heat dissipation fan blows the external cold air to the condenser 5 for heat dissipation, and then the airflow blowing through the condenser 5 is discharged from the smoke exhaust cavity 111 along with the oil smoke.

[0033] Along the airflow path, the water absorption plate 6 is located downstream of the air outlet of the heat dissipation fan. In this way, the airflow driven by the heat dissipation fan will flow through the water absorption plate 6, and the airflow will cause the condensed water to evaporate and be discharged from the smoke exhaust chamber 111 along with the oil smoke, so that the water absorption plate 6 can be reused.

[0034] Example 3

[0035] like Figure 4 As shown, the difference between Example 3 and Example 2 is that the setting position of the water absorption plate 6 is different from that of Example 2.

[0036] Along the airflow path, the water absorption plate 6 is located upstream of the air inlet of the heat dissipation fan. In this way, the airflow driven by the heat dissipation fan will flow through the water absorption plate 6, and the airflow will cause the condensed water to evaporate, so that the water absorption plate 6 can be reused.
