Refrigerated range hood

Abstract

A refrigerated range hood includes a range hood fan installed inside a fan frame and a refrigeration module installed outside the fan frame. The refrigeration module includes a compressor, condenser, evaporator, cooling fan, and indoor unit fan. The fan frame has ventilation openings, and the outside of the fan frame has a heat dissipation channel and an air outlet channel. The condenser and cooling fan are located in the heat dissipation channel, while the evaporator and indoor unit fan are located in the air outlet channel. The air outlet of the heat dissipation channel is connected to the air inlet of the range hood fan through the ventilation openings. The evaporator and condenser are arranged on the same vertical plane, with the evaporator directly above the condenser. The advantages of this invention are: when the refrigerated range hood operates in refrigeration mode, the heat from the condenser enters the fan frame through the ventilation openings and is then discharged to the outside by the range hood fan. Furthermore, the condensate water condensed on the evaporator can flow smoothly into the condenser, thus achieving dual cooling of the condenser through both air and water cooling, effectively improving the condenser's heat dissipation effect.

Description

Technical Field

[0001] This utility model relates to a range hood, and more particularly to a refrigerated range hood. Background Technology

[0002] Existing technologies disclose various types of refrigerated range hoods, which add air conditioning components to the existing range hood platform. The compressor, condenser, and evaporator are connected via refrigerant piping. These refrigerated range hoods can perform both the functions of a range hood and an air conditioner. Currently, the condenser of refrigerated range hoods on the market often dissipates heat by sharing a common flue with the range hood, exhausting the heat into a shared flue. For example, the "Kitchen Air Conditioning System" disclosed in Chinese invention patent number 201811150307.4 (authorization announcement number CN110966676 B) has its condenser installed in the air outlet duct downstream of the range hood fan. The air exhausted by the range hood fan blows towards the condenser and is ultimately discharged into the shared flue through the flue pipe, carrying away the heat from the condenser and improving air conditioning efficiency. However, installing the condenser in the air outlet duct can easily lead to oil fume contamination of the condenser. Furthermore, the relatively high temperature of the oil fume airflow can result in poor heat dissipation from the condenser. Furthermore, existing air conditioning refrigeration systems generate condensate that drips into a drip tray and flows outdoors through a sloped pipe, or the condensate is collected in a water box and emptied periodically. This does not achieve efficient utilization of the condensate. Therefore, further improvements are needed to existing refrigeration-type range hoods. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cooling range hood that can effectively dissipate heat from the condenser by using condensate water, in light of the existing technology described above.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a refrigerated range hood, including a fan frame, a range hood fan installed inside the fan frame, and a refrigeration module installed outside the fan frame. The refrigeration module includes a compressor, a condenser, an evaporator, a cooling fan, and an indoor unit fan. The compressor, condenser, and evaporator are connected through refrigerant pipes. The characteristic feature is that: the fan frame has a ventilation opening, and the fan frame is provided with a heat dissipation channel and an air outlet channel. The condenser and the cooling fan are located in the heat dissipation channel, and the evaporator and the indoor unit fan are located in the air outlet channel. The air outlet of the heat dissipation channel is connected to the air inlet of the range hood fan through the ventilation opening. The evaporator and the condenser are arranged on the same vertical plane, and the evaporator is located directly above the condenser.

[0005] To improve the heat dissipation effect of condensate on the condenser, the copper tubes of the evaporator are arranged horizontally, and the fins of the evaporator are arranged vertically. Similarly, the copper tubes of the condenser are arranged vertically, and the fins of the condenser are arranged horizontally. This arrangement allows the condensate produced by the evaporator to be evenly distributed onto the upper part of the condenser through the fins. The condensate then diffuses to both sides and flows downwards along the fins, achieving full coverage of the condensate on the condenser. This increases the spreading area and the length of the condensate's movement path, thereby achieving efficient evaporation of the condensate and improving the heat dissipation effect of the condenser.

[0006] To improve the energy efficiency of the air conditioner, the air intake surface of the evaporator faces the air inlet of the air outlet channel, and the air intake surface of the condenser faces the air inlet of the heat dissipation channel.

[0007] Preferably, along the airflow direction, the indoor unit fan is located downstream of the evaporator, and the cooling fan is located downstream of the condenser.

[0008] To make the cooling module more compact and reduce costs, both the cooling fan and the indoor unit fan are centrifugal fans. The cooling fan is located below the indoor unit fan and is coaxially arranged, and the cooling fan and the indoor unit fan share a single drive motor.

[0009] In a further preferred embodiment, the impellers of both the cooling fan and the indoor unit fan are vertically oriented.

[0010] In order for any unused condensate from the condenser to flow into the oil cup, a water collection box is installed below the condenser. The outlet of the water collection box is connected to the oil cup of the range hood via a drain pipe.

[0011] The refrigeration module and the fan frame can be arranged in various ways. The refrigeration module and the fan frame are arranged adjacent to each other on the left and right sides. Correspondingly, the ventilation opening is located on the left or right side wall of the fan frame.

[0012] Further preferably, a valve plate is installed at the vent. With this configuration, in cooling mode, the valve plate opens, and the heat from the condenser is exhausted through the exhaust fan. In mode where only the exhaust fan is on, the valve plate closes to prevent oil fumes from contaminating the heat dissipation channel.

[0013] As a preferred embodiment of any of the above solutions, the refrigerated range hood includes a housing, with the fan frame and refrigeration module both installed inside the housing. An air outlet panel is installed on the housing, and the air outlet of the air outlet channel is fluidly connected to the air inlet of the air outlet panel.

[0014] Compared with the prior art, the advantages of this utility model are as follows: The cooling range hood has a heat dissipation channel and an air outlet channel on the outside of the fan frame. The air outlet of the heat dissipation channel is connected to the air inlet of the range hood through the ventilation port. The heat of the condenser enters the fan frame through the ventilation port and is then discharged to the outside by the range hood. In addition, since the evaporator and condenser are set on the same vertical plane and the evaporator is located directly above the condenser, the condensate water condensed on the evaporator can flow smoothly into the condenser, thereby achieving dual cooling of the condenser through air cooling and water cooling, effectively improving the heat dissipation effect of the condenser.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 3 As shown, the refrigerated range hood of this embodiment includes a casing (not shown in the figure). A fan frame 1 and a refrigeration module 3 are installed inside the casing. A range hood fan 2 is installed inside the fan frame 1, and the refrigeration module 3 is located on the right side of the fan frame 1. The refrigeration module 3 includes a compressor 31, a condenser 32, an evaporator 33, a cooling fan 34, and an indoor unit fan 35. The compressor 31, condenser 32, and evaporator 33 are connected via a refrigerant pipe 36. The above structure can be referenced from existing refrigerated range hoods; specific details will not be elaborated further.

[0020] In this embodiment, a ventilation opening 11 is provided on the right side wall of the fan frame 1. A heat dissipation channel 37 and an air outlet channel 38 are provided on the outside of the fan frame 1. The condenser 32 and the cooling fan 34 are located within the heat dissipation channel 37, while the evaporator 33 and the indoor unit fan 35 are located within the air outlet channel 38. The air outlet of the heat dissipation channel 37 is connected to the air inlet of the range hood 2 through the ventilation opening 11. A valve plate 7 is installed on the ventilation opening 11. In cooling mode, the valve plate 7 is open, meaning the ventilation opening 11 is open, allowing heat from the condenser 32 to enter the range hood 2 through the ventilation opening 11 and ultimately be discharged to the exhaust pipe. In the mode where only the range hood is on, the valve plate 7 is closed, meaning the ventilation opening 11 is closed, preventing fumes from entering the heat dissipation channel 37 and contaminating the condenser 32 and the cooling fan 34. An air outlet panel 8 is installed on the casing, and the air outlet of the air outlet channel 38 is fluidly connected to the air inlet of the air outlet panel 8. When the cooling system is working, cool air is blown out through the air outlet panel 8, enhancing the user's cooking experience.

[0021] In this embodiment, the evaporator 33 and the condenser 32 are arranged on the same vertical plane, with the evaporator 33 positioned directly above the condenser 32. Specifically, the copper tubes of the evaporator 33 are arranged horizontally, and the fins of the evaporator 33 are arranged vertically. The copper tubes of the condenser 32 are arranged vertically, and the fins of the condenser 32 are arranged horizontally. When the refrigeration system is operating, the condensate produced by the evaporator 33 can be evenly sprayed onto the upper part of the condenser 32 through the fins. The condensate diffuses to both sides and flows downwards along the fins, achieving full coverage of the condensate on the condenser 32. This increases the spreading area and the length of the flow path of the condensate, thereby achieving efficient evaporation of the condensate and improving the heat dissipation effect of the condenser 32.

[0022] like Figure 1 As shown, the air intake surface of the evaporator 33 faces the air inlet of the air outlet duct 38, and the air intake surface of the condenser 32 faces the air inlet of the heat dissipation duct 37. Furthermore, along the airflow direction, the indoor unit fan 35 is located downstream of the evaporator 33, and the heat dissipation fan 34 is located downstream of the condenser 32. The indoor unit fan 35 creates a suction effect on the evaporator 33, and the heat dissipation fan 34 creates a suction effect on the condenser 32.

[0023] In this embodiment, both the cooling fan 34 and the indoor unit fan 35 are centrifugal fans. The cooling fan 34 is located below the indoor unit fan 35 and is coaxially arranged. The impeller axes of both the cooling fan 34 and the indoor unit fan 35 are vertically aligned, and they share a single drive motor 39. Thus, driven by the drive motor 39, the cooling fan 34 and the indoor unit fan 35 rotate synchronously. Compared to conventional solutions, this eliminates the need for a single motor, resulting in a more compact structure and reduced costs.

[0024] Additionally, a water collection box 4 is installed below the condenser 32, and the outlet of the water collection box 4 is connected to the oil cup 6 of the range hood via a drain pipe 5. Unused condensate from the condenser 32 flows into the oil cup 6 through the drain pipe 5, preventing it from dripping into the range hood or onto the cooktop.

[0025] The positional relationship between the fan frame 1 and the cooling module 3 is not limited to this embodiment. For example, the cooling module 3 can also be installed on the left, above or below the fan frame 1. Accordingly, the position of the ventilation opening 11 can be adjusted accordingly. These changes are all considered to be within the protection scope of this utility model.

[0026] This range hood can be controlled by a voice module, which is equipped with a control module, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the range hood to perform corresponding operations, thereby realizing intelligent control of the range hood and improving the user experience.

[0027] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0028] The term "fluid connectivity" as used in this utility model refers to the spatial relationship between two components or parts, collectively referred to as the first part and the second part, meaning that a fluid, gas, liquid, or a mixture of both can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, flow guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
