Description

Technical Field

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

[0002] In order to improve the cooking experience, people have invented various refrigeration-type range hoods, which can realize all the functions of range hoods and the functions of air conditioners. For example, the "A Kind of Air-conditioning Range Hood" disclosed in the Chinese utility model patent with patent number 202122814657.X (authorization announcement number CN216557289U) has a wind valve installed at the outlet of the range hood fan for switching one of the first and second smoke exhaust channels to be connected to the outlet of the range hood fan, and the condenser is arranged in the first smoke exhaust channel. When the refrigeration system is started, the wind discharged by the range hood fan will be blown to the condenser. Since the wind contains many oil fume particles, in order to keep the surface of the condenser clean, it is often necessary to add an additional electrostatic device to filter these fine particles. The installation of the electrostatic device not only increases the cost but also brings the risk of error, reduces reliability, and is not conducive to later maintenance. At the same time, the internal space of the range hood is relatively small, and the requirements for space layout become higher. The production and assembly are more troublesome, and the assembly efficiency is low. Moreover, the electrostatic device often cannot completely remove the oil fume particles in the wind. When the wind from the fan blows towards the condenser, it will pollute the surface of the condenser and reduce the working efficiency and life of the condenser. The range hood needs to add a three-way device to the smoke pipe and adopt a dual-channel structure. The first smoke exhaust channel constitutes a heat dissipation channel, and the second smoke exhaust channel constitutes a direct exhaust channel. In different working modes, the smoke can be discharged from the heat dissipation channel or the direct exhaust channel by switching the air valve. And after the smoke enters the heat dissipation channel, it needs to turn two 90° bends before being discharged, which has a large wind resistance and affects the smoke exhaust effect. Since it is necessary to consider the exhaust path of the wind under two working conditions and avoid drilling two holes in the wall, the wind discharged from these two paths needs to be finally converged and discharged outdoors. The additional three-way device increases the cost compared to the single smoke pipe, and because the smoke pipe has more bends, it is not conducive to the exhaust of oil fume. In addition, the existing refrigeration range hood usually has an air-conditioning outlet at the top of the front of the casing. The cold air blown out of the air-conditioning outlet reaches the user at a long distance, causing greater damage and poor user experience. In summary, there is a need to further improve the existing refrigeration type range hoods. Utility Model Content

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 8 As shown, the refrigeration type range hood of this embodiment includes a range hood module 1, an external heat dissipation module 2 and an internal refrigeration module 3. The range hood module 1 includes a shell 11 and a range hood fan 12 installed inside the shell 11. The external heat dissipation module 2 and the internal refrigeration module 3 can be detachably installed on the outside of the shell 11.

[0027] The external unit heat dissipation module 2 includes a compressor 21, a condenser 22 and a heat dissipation fan 23, and the internal unit refrigeration module 3 includes an evaporator 31 and an internal unit fan 32.

Its working principle is the same as that of the existing air conditioner and will not be described in detail here.

[0028] The shell 11 of this embodiment includes an upper box body 111 and a lower cavity body 112, and the lower cavity body 112 extends forward from the upper box body 111. The air guide channel 5 and the air outlet assembly 4 are both arranged above the lower cavity body 112 and located at the front side of the upper box body 111, and the air outlet assembly 4 is installed at the bottom of the air guide channel 5. The air outlet of the indoor fan 32 extends forward from the upper box body 111 and faces vertically downward. The air inlet of the air guide channel 5 is connected with the air outlet of the indoor fan 32, and the air outlet of the air guide channel 5 is connected with the air outlet assembly 4. The air outlet assembly 4 is located in the middle area in the height direction of the shell body 11 and is arranged horizontally. The air outlet of the air outlet assembly 4 faces the front side, that is, a central front air outlet structure is adopted. The width of the air outlet of the air guide channel 5 is greater than the width of the air inlet of the air guide channel 5, and specifically presents a trapezoidal structure with a small top and a large bottom.

[0029] The internal refrigeration module of this embodiment is installed above the upper box body 111, and the left and right width of the lower cavity 112 is greater than the left and right width of the upper box body 111. Figure 1 The direction indicated by the middle arrow A is right, and the external heat dissipation module 2 is arranged on the right side of the upper box body 111 and above the lower cavity 112.
