Refrigeration type range hood

Abstract

A refrigeration type extractor hood comprises a machine shell, an oil smoke suction module comprises an oil smoke suction fan, a heat dissipation module comprises a condenser and a heat dissipation fan, a refrigeration mode comprises an evaporator and an inner machine fan, and a water treatment module collects condensate water condensed on the evaporator and conveys the condensate water to the condenser. An air outlet of the cooling fan is in fluid communication with an air inlet of the oil smoke suction fan, the condenser is provided with a water distribution area and a non-water distribution area, and condensate water output by the water treatment module falls on the water distribution area and flows through the water distribution area. When the refrigeration type range hood works in a refrigeration mode, condensed water flows to the water distribution area of the condenser, and when the refrigeration type range hood needs to increase the air quantity and the pressure of a heat dissipation fan, most of the heat dissipation air quantity passes through the low-pressure side, namely the non-water distribution area, of the condenser, so that the air quantity of the water distribution area is relatively reduced, and the corresponding air speed is also reduced; and water on the condenser cannot be sucked into the cooling fan and then enters the range hood fan, so that water leakage is avoided, and the working reliability of the refrigeration type range hood is improved.

Description

Technical Field

[0001] The utility model relates to an oil fume exhauster, in particular to a refrigerating type oil fume exhauster. Background Art

[0002] Various refrigerating type oil fume exhausters are disclosed in the prior art. An air conditioner component is added on the basis of the oil fume exhauster platform, which can not only realize all functions of the oil fume exhauster, but also realize the functions of the air conditioner. When working in the refrigerating mode, the condenser needs to dissipate heat. At present, the condenser is usually placed in the oil fume channel, and the oil fume exhaust fan is used to dissipate heat and cool it. For example, the "Range Hood" disclosed in the Chinese utility model patent with the patent number 201620118025.6 (the authorized announcement number is CN 205481215U) places the condensers in the smoke exhaust cavity. Although the air with oil fume can be purified by the centrifugal fan of the oil fume exhauster and then used to dissipate heat from the condensers, with the prolongation of the working time, oil stains will adhere to the condensers, thus affecting the heat exchange capacity of the condensers and further affecting the refrigerating effect. At present, a purification device is usually installed at the front end of the condenser. After setting the purification device, it is easy to cause the smoke exhaust channel to be unsmooth, with a high noise, and the purification device has a high cost and a high failure rate, and needs to be maintained regularly. As an improvement, people have also invented another refrigerating type oil fume exhauster, which places the entire heat dissipation module outside the oil fume exhaust fan, and the heat of the condenser of the heat dissipation module is taken away by the oil fume exhaust fan, which can avoid oil fume pollution of the condenser. However, during the use of the refrigerating oil fume exhauster, the air of the heat dissipation fan is discharged to the outside after passing through the air of the oil fume exhaust fan. Due to the water treatment circulation process of the refrigerating oil fume exhauster, the condenser will be covered with condensed water. When the air volume and pressure of the heat dissipation fan need to be increased, the water on the condenser will be sucked into the heat dissipation fan and then into the oil fume exhauster fan, causing water leakage and quality problems. To sum up, it is necessary to further improve the existing refrigerating type oil fume exhauster. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a refrigerating type oil fume exhauster that can avoid condensed water being brought into the oil fume exhaust fan by the heat dissipation fan aiming at the above-mentioned current situation of the prior art.

[0004] The technical solution adopted by the present utility model to solve the above technical problems is as follows: A refrigerated range hood, comprising a casing, wherein an oil fume extraction module, a compressor, a heat dissipation module and a refrigeration module are installed inside the casing. The oil fume extraction module includes an oil fume extraction fan. The heat dissipation module includes a condenser and a heat dissipation fan. The refrigeration module includes an evaporator and an indoor fan. It further includes a water treatment module. The water treatment module can collect the condensed water condensed on the evaporator and transport the collected condensed water to the condenser. It is characterized in that: the air outlet of the heat dissipation fan is in fluid communication with the air inlet of the oil fume extraction fan. The condenser has a water distribution area and a non-water distribution area. The condensed water output by the water treatment module falls on the water distribution area and flows through the water distribution area.

[0005] As a preferred solution, the water distribution area and the non-water distribution area are separated by a partition.

[0006] The partition can have various arrangement modes. Preferably, the partition is arranged vertically, and the water distribution area and the non-water distribution area are respectively arranged on the left and right sides of the condenser.

[0007] Preferably, the partition is arranged horizontally or obliquely, and the water distribution area is arranged below the non-water distribution area.

[0008] As another preferred solution, the condenser includes a first condenser and a second condenser which are arranged side by side and connected in series. The first condenser is the water distribution area, and the second condenser is the non-water distribution area.

[0009] Further preferably, the water distribution area is located on one side of the exhaust inlet of the condenser.

[0010] In order to generate a suction effect on the condenser, a heat dissipation module air inlet is provided at the top of the casing, and the condenser is arranged in the air duct between the heat dissipation module air inlet and the air inlet of the heat dissipation fan.

[0011] In order to facilitate the smooth falling of the condensed water, the condenser is arranged vertically, and the condenser has an opposite air inlet surface and air outlet surface.

[0012] The heat dissipation fan and the oil fume extraction fan can have various arrangement modes. Preferably, the heat dissipation fan and the oil fume extraction fan are centrifugal fans. The heat dissipation fan is arranged above the oil fume extraction fan. The central axis of the heat dissipation fan is parallel to the central axis of the oil fume extraction fan and perpendicular to the front surface of the casing. A ventilation opening is opened on the volute ring wall of the oil fume extraction fan.

The condensed water in the water receiving box can flow into the liquid distributor through the water pump and the second water pipe, and the liquid distributor is located above the water distribution area.

[0014] In order to enable cold air to blow out from the front of the casing, an inner machine air outlet is provided on the front of the casing, and the air outlet of the inner machine fan is connected to the inner machine air outlet through an internal air duct.

[0015] Compared with the prior art, the advantages of the present utility model are as follows: when the refrigerating range hood works in the refrigeration mode, when the condensed water flows to the water distribution area of the condenser, in the case where the air volume and pressure of the heat dissipation fan are required to increase for the refrigerating range hood, most of the heat dissipation air volume will pass through the side with lower pressure of the condenser, that is, the non-water distribution area, so that the air volume in the water distribution area will relatively decrease, and the corresponding wind speed will also decrease. In this way, the water on the condenser will not be sucked into the heat dissipation fan and then into the range hood fan, and water leakage will not occur, improving the working reliability of the refrigerating range hood.

[0021] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] As shown in FIGS. 1 to Figure 5As shown in the figure, the refrigerating range hood of this embodiment includes a housing 1, and an oil fume suction module 2, a compressor 3, a heat dissipation module 4, a refrigeration module 5 and a water treatment module 6 are installed inside the housing 1. Among them, the oil fume suction module 2 includes an oil fume suction fan 21, the oil fume suction fan 21 is a centrifugal fan, and a ventilation opening 22 is formed on the volute annular wall of the oil fume suction fan 21. The heat dissipation module 4 includes a condenser 41 and a heat dissipation fan 42. A heat dissipation module air inlet 43 is provided at the top of the housing 1, and the condenser 41 is arranged in the air duct between the heat dissipation module air inlet 43 and the air inlet of the heat dissipation fan 42, that is, the heat dissipation fan 42 forms a suction effect on the condenser 41. The heat dissipation fan 42 is a centrifugal fan, the heat dissipation fan 42 is arranged above the oil fume suction fan 21, the central axis of the heat dissipation fan 42 is parallel to the central axis of the oil fume suction fan 21 and perpendicular to the front surface of the housing 1, and the air outlet of the heat dissipation fan 42 is connected to the air inlet of the oil fume suction fan 21 through the ventilation opening 22. The refrigeration module 5 includes an evaporator 51 and an indoor unit fan 52. An indoor unit air outlet 11 is provided on the front surface of the housing 1, and the air outlet of the indoor unit fan 52 is connected to the indoor unit air outlet 11 through an internal air duct 7.

[0023] The compressor 3, the condenser 41 and the evaporator 51 are connected through a refrigerant pipeline 8 to form an air conditioning assembly, and its specific working principle is the same as that of the existing air conditioner, and will not be elaborated here.

[0024] When working in the refrigeration mode, the heat of the condenser 41 enters the oil fume suction fan 21 through the ventilation opening 22 and is discharged outward together with the oil fume; the cold air blows forward through the indoor unit air outlet 11 to improve the user's cooking experience.

[0025] The condenser 41 of this embodiment is arranged vertically. The condenser 41 has an opposite air inlet surface 412 and an air outlet surface 413. The condenser 41 is separated into a water distribution area a and a non-water distribution area b by a vertically arranged partition c. The water distribution area a and the non-water distribution area b are respectively arranged on the left and right sides of the condenser 41. Since the temperature on the exhaust gas inlet side of the condenser 41 is higher than that on the exhaust gas outlet side, therefore, the water distribution area a of this embodiment is located on one side of the exhaust gas inlet 411 of the condenser 41 to obtain a better cooling and heat exchange effect. In addition, the partition c can also be arranged horizontally or obliquely, and the water distribution area a is located below the non-water distribution area b. In addition, the condenser 41 can also be formed by combining two independent condensers. For example, the condenser 41 can include a first condenser and a second condenser arranged side by side and connected in series. The entire first condenser constitutes the water distribution area, and the entire second condenser constitutes the non-water distribution area.

[0026] The water treatment module of this embodiment includes a water receiving box 61, a water pump 62, a first water pipe 63, a second water pipe 64, and a liquid distributor 65. The water receiving box 61 is arranged below the evaporator 51. The condensed water on the surface of the evaporator 51 flows into the water receiving box 61 through the first water pipe 63. The condensed water in the water receiving box 61 can flow into the liquid distributor 65 through the water pump 62 and the second water pipe 64. The liquid distributor 65 is located above the water distribution area a. During operation, the water treatment module can collect the condensed water condensed on the evaporator 51 and transport the collected condensed water to the water distribution area a of the condenser 41 and flow through the water distribution area a.

[0027] When the refrigerating range hood is operating, when the condensed water flows to the water distribution area a of the condenser, in the case where the air volume and pressure of the heat dissipation fan 42 are required to increase in the refrigerating range hood, most of the heat dissipation air volume will pass through the side with lower pressure of the condenser, that is, the non-water distribution area b, so that the air volume in the water distribution area a will relatively decrease, and the corresponding wind speed will also decrease. In this way, the water on the condenser 41 will not be sucked into the heat dissipation fan 42 and then into the oil fume extraction fan 21, and water leakage will not occur, improving the working reliability of the refrigerating range hood.

[0028] Experimental tests found that when the wind speed of the condenser is greater than about 1.5 m / s, the water on the condenser 41 covered with water will be blown off (related to the parameters of the condenser, such as fin type, fin pitch, tube pitch, etc.). The blown-off condensed water will then enter the oil fume extraction fan 21 through the ventilation opening 22, which may cause water leakage. Therefore, the separation ratio of the left and right sides of the condenser 41 should be appropriate to ensure that when the condenser 41 requires the maximum air volume, the maximum wind speed of the water-covered side of the condenser 41, that is, the water distribution area a, does not exceed 1.5 m / s.
