Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of range hoods, in particular to a range hood with a cooling type smoke guide plate.
Background Art
[0002] A range hood, also known as an extraction hood, is a kitchen appliance for purifying the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste generated by the stove combustion and the harmful oil fumes produced during the cooking process outdoors. At the same time, the oil fumes are condensed and collected to reduce pollution, purify the air, and have the safety guarantee functions of preventing poisoning and explosion. During actual use, the smoking module inside the range hood body is used to suck the oil fumes in the room. When sucking the oil fumes, the smoke guide plate arranged inside the range hood body guides the oil fumes so that they are discharged to the outside through the smoke exhaust pipe communicated with the smoking module through the smoking module, thereby realizing the cleaning of the oil fumes in the kitchen.
[0003] In the above solution, it mainly uses the smoke guide plate to directly guide the flue gas into the smoking module, and the smoking module transmits the flue gas to the outside through the smoke exhaust pipe, thereby realizing the discharge of the oil fumes. Although the smoke guide plate can guide the oil fumes, when the oil fumes are guided by the smoke guide plate into the inside of the range hood body, the amount of oil fumes is large. If the oil in the oil fumes is not separated, it is very easy for the oil to enter the range hood quickly and adhere to the inside of the range hood. Correspondingly, as the oil in the flue gas increases, the adhesion speed of the oil fumes will also increase. If the adhesion speed of the oil fumes increases, the number of times for personnel to clean the oil fumes inside the range hood body will also increase, which will bring unnecessary trouble to the personnel and greatly increase the maintenance cost of cleaning the range hood body.
Content of the Utility Model
[0004] The purpose of the utility model is to solve the problems in the prior art and propose a range hood with a cooling type smoke guide plate, which can extract oil fumes.
[0005] To achieve the above purpose, the utility model proposes a range hood with a cooling type smoke guide plate, including: a range hood body, a smoke guide plate fixedly connected to the range hood body, and a smoking module arranged inside the range hood body and extending to the outside at one end.
[0006] A temperature guiding pipe for cooling water to enter is fixedly connected to the side of the smoke guide plate close to the range hood body, and both ends of the temperature guiding pipe extend outside the range hood body and are connected to an external condensation system.
[0007] A connecting frame is detachably connected to the side of the smoke guide plate away from the temperature guiding pipe, and a chamber for flue gas to enter is formed between the connecting frame and the smoke guide plate.
[0008] One end of the smoking module communicates with the connection frame through a pipeline, and an air inlet for oil fume to enter is provided at the end of the connection frame far from the smoking module.
[0009] Preferably, a first temperature guide plate is fixedly connected between the smoke guide plate and the temperature guide pipe. Horizontally arranged in parallel on this temperature guide plate are fixedly connected second temperature guide plates. One end of the second temperature guide plate penetrates through the smoke guide plate and is located in the chamber, and is attached to the inner wall of the connection frame.
[0010] Preferably, a third temperature guide plate is fixedly connected obliquely between two adjacent second temperature guide plates, and a number of oil discharge holes for oil discharge are penetrated through the third temperature guide plate.
[0011] Preferably, a knob is rotatably connected to the connection frame, and one end of the knob penetrates through the connection frame and is threadedly connected to the smoke guide plate.
[0012] Preferably, a storage box with a top slot is provided at one end of the range hood body close to the air inlet.
[0013] Preferably, a slider is fixedly connected to the bottom of the storage box, and the slider is slidably connected to the range hood body.
[0014] Preferably, a fixing plate is rotatably connected to the range hood body, an elastic limiting column is connected to the fixing plate, and a limiting hole for the limiting column to enter is provided on the range hood body.
[0015] The beneficial effects of the present utility model: Compared with the prior art, by arranging a temperature guide pipe on the back of the smoke guide plate in the present utility model, and enabling the condensed water to circulate in the temperature guide pipe, the temperature guide pipe can be cooled. Once the temperature guide pipe is cooled, the temperature on the temperature guide pipe is transmitted to the smoke guide plate by means of heat transfer, so that the smoke guide plate cools the oil fume after cooling. When the oil fume is cooled, part of the oil is separated from the flue gas. The oil will be discharged to the outside along the guide of the smoke guide plate, and the flue gas will enter the smoking module, thereby realizing the separation of part of the oil fume and the flue gas. By cooling the oil fume and separating part of the oil from the flue gas, the amount of oil in the flue gas is reduced, thereby indirectly reducing the situation of oil adhesion inside the range hood, and further greatly reducing the cleaning frequency inside the oil fume, and indirectly reducing the maintenance cost of range hood cleaning.

[0026] Such as Figures 1 to 4, the present utility model discloses an oil fume extractor with a cooling type smoke guide plate, including: an oil fume extractor body 1, a smoke guide plate 2 fixedly connected to the oil fume extractor body 1, and a smoking module 3 disposed inside the oil fume extractor body 1 and extending to the outside at one end, wherein the smoking module 3 in the present utility model is the fan assembly in the patent application number CN202210814179.9, which has the effect of smoking;
[0027] The oil fume extractor of the present utility model further includes:
[0028] A temperature guiding pipe 4, which is fixedly connected to the side of the smoke guide plate 2 close to the oil fume extractor body 1, and its two ends respectively extend outside the oil fume extractor body 1 and communicate with the external condensation system. Through the condensation system, condensed water can be transmitted to be condensed in the temperature guiding pipe 4, so as to realize the cooling of the temperature guiding pipe 4. After one end of the temperature guiding pipe 4 is cooled, it will cool the smoke guide plate 2, thereby realizing the cooling of the smoke guide plate 2 to the oil fume, separating the oil fume and the flue gas. It is worth mentioning that the material of the temperature guiding plate is a copper plate;
[0029] A connection frame 5, which is detachably connected to the side of the smoke guide plate 2 away from the temperature guiding plate 8, and a chamber 6 for the flue gas to enter is formed between it and the smoke guide plate 2. This chamber 6 is mainly a place for the flue gas to transfer. It is worth mentioning that one end of the smoking module 3 communicates with the connection frame 5 through a pipeline, which can mainly suck the oil fume in the chamber 6. An air inlet 7 is opened at the end of the connection frame 5 away from the smoking module 3, which is mainly used to transmit the oil fume into the chamber 6.
[0030] The condensation system in the present utility model is mainly composed of a circulation tank, a liquid pumping pump 1, a liquid pumping pump 2 and a cooler connected. Among them, the liquid pumping pump is fixedly connected in the circulation tank. One end of the liquid pumping pump communicates with the temperature guiding pipe 4 through a pipeline, and one end of the temperature guiding pipe 4 communicates with the circulation tank, so as to realize the circulation of condensed water in the temperature guiding pipe 4. The condensation of the condensed water depends entirely on the cooler and the liquid pumping pump 2. Among them, the liquid pumping pump 2 is fixedly connected in the circulation tank. The liquid pumping pump 2 communicates with the cooler through a pipeline, and the cooler communicates with the circulation tank. When the liquid pumping pump 2 transmits the condensed water into the cooler, the cooler cools the condensed water and then transports it into the circulation tank, so as to realize the cooling of the condensed water in the circulation tank (not shown in this structure diagram).
[0031] Specifically, since a temperature guiding plate 8 is fixedly connected between the smoke guide plate 2 and the temperature guiding pipe 4, and temperature guiding plates 9 are fixedly connected in a horizontal array on this temperature guiding plate. One end of the temperature guiding plate 9 penetrates the smoke guide plate 2 and is located in the chamber 6 and is in contact with the inner wall of the connection frame 5. Therefore, the temperature guiding pipe 4 can transfer the temperature to the temperature guiding plate 8, and the temperature guiding plate 8 guides the temperature to the temperature guiding plate 9, and the temperature guiding plate 9 is used to guide the temperature of the flue gas, so that it contacts the oil fume. By increasing the contact surface of the temperature guiding plate 9 for the oil fume, the cooling effect of the oil fume is increased, and the separation effect of the oil fume is further improved.
[0032] Specifically, a third heat conduction plate 10 is fixedly connected obliquely between two adjacent second heat conduction plates 9. A number of oil outlet holes 11 for oil supply and discharge penetrate through the third heat conduction plate 10. The third heat conduction plate 10 is in contact with the oil fume mainly to increase the contact surface of the oil fume, further improving the cooling effect of the oil fume. The oil outlet holes 11 are mainly used to discharge the oil in the chamber 6.
[0033] Specifically, when the connection frame 5 needs to be disassembled, since a knob 12 is rotatably connected to the connection frame 5, and one end of the knob 12 penetrates through the connection frame 5 and is threadedly connected to the smoke guide plate 2, the connection frame 5 can be separated by rotating the knob 12, facilitating the disassembly of the connection frame 5 and the cleaning of the interior of the chamber 6 by personnel.
[0034] Specifically, a storage box 13 with a top slot is provided at one end of the range hood body 1 close to the smoke inlet 7, mainly for storing oil.
[0035] Specifically, since a slider 14 is fixedly connected to the bottom of the storage box 13, and the slider 14 is slidably connected to the range hood body 1, personnel can slide the storage box 13 to separate the storage box 13 from the range hood body 1, facilitating the cleaning of the storage box 13 by personnel.
[0036] Specifically, since a fixing plate 15 is rotatably connected to the range hood body 1, a limiting column 16 is elastically connected to the fixing plate 15, and a limiting hole 17 for the limiting column 16 to enter is provided on the range hood body 1. By rotating the fixing plate 15 by personnel and putting the limiting column 16 into the limiting hole 17, the storage box 13 can be limited. It is worth mentioning that the limiting column 16 is connected by a spring 18, and the spring 18 is fixedly connected to the fixing plate 15, with one end fixedly connected to the limiting column 16, enabling the reset of the limiting column 16.
[0037] Principle of the present utility model: The condensed water circulates in the heat conduction pipe 4 to cool the heat conduction pipe 4. Once the heat conduction pipe 4 is cooled, the temperature is transferred to the smoke guide plate 2 by means of heat transfer. After the smoke guide plate receives the temperature, it is cooled and cools the smoke in the chamber 6, separating the oil from the smoke, and reducing the situation of oil entering the range hood body 1.
[0038] The above embodiments are illustrative of the present utility model, not restrictive thereof. Any scheme obtained by simply transforming the present utility model falls within the protection scope of the present utility model.
