Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a refrigeration type range hood. Background Art

[0002] To enhance the user's cooking experience, various refrigeration-type range hoods have been invented. These range hoods add air conditioning components to the range hood platform, integrating a compressor, a heat dissipation module, and a refrigeration module. The heat dissipation module includes a heat dissipation fan and a condenser, while the refrigeration module includes an internal fan and an evaporator. Existing refrigeration-type range hoods generally have their air outlets located on the top edge of the cabinet door, embedding the air outlets within the cabinet. While this provides good overall performance, the high position of the air outlets means that when standing in front of the range hood, the cool air cannot reach them or blows directly over their heads, resulting in poor comfort. Furthermore, the air outlet distance is far, causing the user to perceive a high air temperature without a sense of coolness. This type of air outlet structure also often suffers from insufficient air outlet width, making it difficult to blow cool air from left to right. Furthermore, the air outlet frame of the existing air outlet module needs to be installed separately on the top edge of the cabinet and cannot be installed together with the entire machine. Although the prior art also discloses a structure in which an air-conditioning outlet is integrated on a range hood, such as the "Air-conditioning Hood" disclosed in the Chinese invention patent application with application number 201810525673.7 (application publication number CN 108397807 A), the air-conditioning hood includes: an oil fume component and an air-conditioning component, wherein the oil fume component includes an oil fume channel, the air-conditioning component includes a condenser component, the condenser component includes a condensation air inlet and a condensation air outlet, the condensation air outlet is connected to the oil fume channel, and the condensation air inlet is independent of the oil fume channel, the evaporator component includes an evaporation air inlet, an evaporation air outlet and an evaporator, the evaporation air outlet can be formed on the front wall of the range hood housing, so that the refrigerated cold air can be blown out from the front of the range hood housing, the evaporation air outlet is arranged on the upper part of the entire range hood, far away from the cook, and the comfort needs to be further improved. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a refrigeration range hood with a short distance between the internal fan and the cold air outlet module so that the cold air can be blown close to the cook in response to the above-mentioned existing technical status.

[0004] The heat dissipation fan of described outer combustion gas heating unit is connected with the engine room of cooling fan and the cooling fan is connected with the engine room of cooling fan.

[0005] In order to shorten the distance between the air outlet of the indoor fan and the air inlet of the cold air outlet module, the air outlet of the indoor fan faces downward and is adjacent to the top plate of the lower cavity.

[0006] In order to allow the cold air blown out from the air outlet of the indoor fan to smoothly enter the cold air outlet module, the air outlet of the indoor fan is connected to the air inlet of the cold air outlet module through an adapter.

[0007] The indoor fan can be distributed in a variety of ways. Preferably, the indoor fan is a vertically arranged centrifugal fan, and the central axis of the impeller of the indoor fan is horizontally distributed in the front-to-back direction or horizontally distributed in the left-to-right direction.

[0008] In order to enable the refrigeration module to smoothly take in and out air, the refrigeration module includes an air inlet cavity, an air inlet cavity air inlet is opened on the top of the air inlet cavity, an air inlet cavity air outlet is opened on the side of the air inlet cavity, and the air inlet of the internal fan is opposite to the air inlet cavity air outlet.

[0009] As a preferred embodiment, the air inlet cavity comprises an upper air inlet cavity and a lower air inlet cavity. The evaporator is mounted in the upper air inlet cavity, with the top opening of the upper air inlet cavity constituting the air inlet of the air inlet cavity. The internal unit fan is located on the side of the lower air inlet cavity, with the side opening of the lower air inlet cavity constituting the air outlet of the air inlet cavity. This arrangement results in a relatively high air inlet cavity, with the evaporator positioned above the outlet fan.

[0010] Further preferably, the upper air inlet cavity is arranged adjacent to the heat dissipation module on the left and right, and the air inlet of the heat dissipation module and the air inlet of the air inlet cavity are independent of each other.

[0011] As another preferred solution, the evaporator is installed in the air inlet cavity, and the indoor fan is arranged on the front side of the air inlet cavity.

[0012] As another preferred solution, the evaporator is installed in the air inlet cavity, the air inlet cavity is arranged on the right side of the upper cavity, and the indoor fan is arranged on the right side of the air inlet cavity.

[0013] As a preferred embodiment of any of the above solutions, a fume exhaust fan is installed inside the upper cavity.

[0014] In order to discharge the heat of the condenser through the range hood fan, the range hood fan is a centrifugal fan, a heat dissipation air inlet is opened on the volute ring wall of the range hood fan, and the air outlet of the heat dissipation fan is fluidically connected to the heat dissipation air inlet.

[0015] Compared with the prior art, the advantages of the present invention are: the heat dissipation module of the refrigeration type range hood is installed above the upper cavity, and the refrigeration module is arranged above the lower cavity and located on the side of the upper cavity, which will not affect the flue and structural layout of the range hood, and the internal fan and the heat dissipation fan are distributed in a staggered manner in the longitudinal height, so that the air inlet of the internal fan and the air inlet of the heat dissipation fan do not interfere with each other. In addition, the cold air outlet module is installed on the top of the lower cavity and located on the front side of the upper cavity, so that the cold air outlet is closer to the cook, and the distance between the refrigeration module and the cold air outlet module is short, the cold air outlet path is short, less insulation area is required, the cooling capacity attenuation is small, and the user experience is better.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1:

[0028] like Figures 1 to 4 As shown, the refrigeration-type range hood of this embodiment includes a range hood module 1, a compressor 2, a heat dissipation module 3, a refrigeration module 4, and a cold air outlet module 5. The range hood module 1 includes an upper chamber 11 and a lower chamber 12 located below the upper chamber 11. The upper chamber 11 serves as a fan frame, and a range hood fan is installed within the upper chamber 11 (not shown). The heat dissipation module 3 includes a condenser 31 and a heat dissipation fan 32, and the refrigeration module 4 includes an evaporator 41 and an internal fan 42. The compressor 2, condenser 31, and evaporator 41 are interconnected via a refrigerant pipeline 6. Furthermore, the range hood fan utilizes a centrifugal fan. A heat dissipation inlet is provided on the volute ring wall of the range hood fan. The air outlet of the heat dissipation fan 32 is fluidically connected to the heat dissipation inlet. When the refrigeration module is operating, heat generated by the condenser 31 enters the range hood fan through the heat dissipation inlet and is ultimately discharged along with the oil smoke.

[0029] In this embodiment, the heat dissipation module 3 is located above the upper chamber 11, while the cooling module 4 is located above and to the side of the lower chamber 12, without affecting the range hood's air duct and structural layout. Furthermore, the internal fan 42 and the heat dissipation fan 32 are staggered in vertical height, with the heat dissipation fan 32 located above the internal fan 42, which is adjacent to the lower chamber 12. The air outlet of the internal fan 42 faces downward and is adjacent to the ceiling of the lower chamber 12. This closer proximity of the internal fan 42 to the ceiling of the lower chamber 12 reduces the distance between the air outlet of the internal fan 42 and the cold air outlet module, shortening the cold air outlet path, requiring less insulation area, and minimizing cooling capacity attenuation.

[0030] In this embodiment, the cold air outlet module 5 is mounted on the top of the lower chamber 12 and located in front of the upper chamber 11. The air outlet of the cold air outlet module 5 is arranged horizontally, providing a wide air outlet width, reaching both sides of the range hood and providing a better user experience. The internal fan 42 is located at the rear of the cold air outlet module 5, and the air outlet of the internal fan 42 is in fluid communication with the air inlet of the cold air outlet module 5. The air outlet of the internal fan 42 can be directly connected to the air inlet of the cold air outlet module 5.

[0031] The cooling module 4 of this embodiment includes an air inlet cavity 43. An air inlet cavity inlet 430 is formed at the top of the air inlet cavity 43. An air inlet cavity outlet is formed on the side of the air inlet cavity 43. The air inlet of the internal fan 42 faces the air inlet cavity outlet. Specifically, the air inlet cavity 43 includes an upper air inlet cavity 431 and a lower air inlet cavity 432. The upper air inlet cavity 431 is located adjacent to the right side of the heat dissipation module 3. The air inlet of the heat dissipation module 3 and the air inlet cavity inlet 430 are independent of each other and do not interfere with each other. The evaporator 41 is installed in the upper air inlet cavity 431. The top opening of the upper air inlet cavity 431 constitutes the air inlet cavity inlet 430. The internal fan 42 is located on the side of the lower air inlet cavity 432. The side opening of the lower air inlet cavity 432 constitutes the air inlet cavity outlet. In this embodiment, the indoor fan 42 is a vertically mounted centrifugal fan, with the central axis of the impeller of the indoor fan 42 horizontally distributed in a front-to-back direction. When operating in cooling mode, the indoor fan 42 draws kitchen air into the air inlet cavity 43 through the air inlet 430. After heat exchange with the evaporator 41, it is converted into cold air, which is ultimately blown out through the outlet of the cold air outlet module 5, enhancing the user's cooking experience.

[0032] Example 2:

[0033] like Figures 5 to 7 As shown, the air outlet of the indoor fan 42 of this embodiment is connected to the air inlet of the cold air outlet module 5 via the adapter 7. The evaporator 41 of this embodiment is installed in the air inlet cavity 43, which is located on the right side of the upper cavity 11. The indoor fan 42 is located on the right side of the air inlet cavity 43, and the central axis of the impeller of the indoor fan 42 is horizontally distributed in the left and right directions. The remaining structure of this embodiment is the same as that of the first embodiment and will not be further described here.

[0034] Example 3:

[0035] like Figures 8 to 10 As shown, the evaporator 41 of this embodiment is installed in the air inlet cavity 43, and the indoor fan 42 is located in front of the air inlet cavity 43. The central axis of the impeller of the indoor fan 42 is horizontally distributed in the front-to-back direction. The remaining structure of this embodiment is the same as that of the second embodiment and will not be further described here.
