[0002] At present, with the improvement of people's living standards, desktop ovens or baking pans for household use have entered thousands of households. However, since oil fumes are generated when baking food, range hoods for desktop use have emerged as the times require. For example, a portable desktop range hood disclosed in Chinese Patent No.: CN202111069384.9 can achieve the effect of filtering grease, but it cannot filter the flue gas. That is, for the product using this technical solution, although the oil fumes are filtered, there is still smoke discharged; another example is the multifunctional range hood disclosed in Chinese Patent No.: CN 200720014517.1, where the exhaust port is connected to the smoke inlet pipe of the filter through a connecting hose, water is contained in the filter, and the lower end of the smoke inlet pipe on the filter is inserted into the water, which solves the problem of oil fume discharge and realizes the filtering of grease and smoke. However, for the product made by this structure, it is difficult to achieve the integration and integration of the product, and it cannot be substantially applied to a small integrated desktop range hood.

[0003] The present invention provides an improved desktop range hood to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the above existing problems and provide an improved desktop range hood. By using the principle that water can filter flue gas and combining with the smoking and exhaust effects of the impeller structure, the small range hood can also achieve the dual functions of grease filtering and flue gas elimination.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An improved desktop range hood includes a base and a main body. The main body is connected to the base. An impeller is connected in the main body through a motor. A smoking air inlet is provided on the main body, and the smoking air inlet is communicated with the air inlet end of the impeller. The characteristics are that a motor cavity and a wind collecting cavity are provided in the main body. The smoking air inlet is arranged on one side of the wind collecting cavity. The motor is installed in the motor cavity, and the main shaft on the motor extends into the wind collecting cavity to be connected with the impeller. A water receiving box is installed at the lower part of the main body. An opening communicating the wind collecting cavity and the water receiving box is provided on the main body. An air outlet is opened at one end of the water receiving box far away from the opening.

[0007] A cabinet is provided at the lower part of the main body. An installation entrance is provided on one side of the cabinet. The water receiving box enters the cabinet through a drawer form from the installation entrance.

[0008] A filter screen assembly is installed at the smoking air inlet. The lower end of the filter screen assembly extends with a filter screen oil nozzle. One end of the cabinet body is provided with an extension part, and a connection port matching the filter screen oil nozzle is opened on the top surface of the extension part. The connection port is communicated with the water receiving box.

[0009] A baffle is arranged on the water receiving box between the opening and the connection port. The baffle divides the water receiving box into a wind guiding area and an oil dripping area. A conducting gap is arranged between the bottom of the baffle and the bottom surface of the water receiving box.

[0010] Two support plates extend from both sides of the seat body. Both sides of the main machine are movably connected with the two support plates through rotating heads, so that the main machine can rotate relative to the seat body.

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments

[0028] First embodiment:

[0029] As Figures 1-6 shown, an improved desktop range hood includes a base body 1 and a main unit 2. The main unit 2 is connected to the base body 1. Inside the main unit 2, a wind wheel 4 is connected through a motor 3. A smoke intake opening 201 is provided on the main unit 2, and the smoke intake opening 201 is communicated with the air inlet end 401 of the wind wheel 4. An electric motor chamber 202 and an air collecting chamber 203 are provided inside the main unit 2. The smoke intake opening 201 is arranged on one side of the air collecting chamber 203. The motor 3 is installed in the electric motor chamber 202, and the main shaft 301 on the motor 3 extends into the air collecting chamber 203 to be connected with the wind wheel 4. A water receiving box 5 is detachably installed at the lower part of the main unit 2. An opening 204 communicating the air collecting chamber 203 and the water receiving box 5 is provided on the main unit 2. An air outlet 501 is opened at one end of the water receiving box 5 far away from the opening 204.

[0030] While the water receiving box 5 can filter the flue gas, it can also collect the filtered grease. It has a high degree of integration, and only by cleaning the water receiving box 5 can the grease be removed.

[0031] A cabinet 205 is provided at the lower part of the main unit 2. The cabinet 205 has a hollow cavity and is suitable for cooperating with the water receiving box 5. The cabinet 205 can be integrally formed with the main unit 2 or externally connected in a split manner. An installation inlet 205-1 is provided on one side of the cabinet 205. The water receiving box 5 enters the cabinet 205 through the form of a drawer from the installation inlet 205-1; the cooperation between the water receiving box 5 in the form of a drawer and the cabinet 205 facilitates the disassembly and installation of the water receiving box 5. The connection between the cabinet 205 and the main unit 2 breaks the defect that the water receiving box or the water-containing container of the existing range hood is external.

[0032] A filter assembly 6 is installed on the smoking air inlet 201, and a filter nozzle 601 extends from the lower end of the filter assembly 6. An extension part 205-2 is provided at one end of the cabinet 205. A connecting port 205-3 cooperating with the filter nozzle 601 is provided on the top surface of the extension part 205-2, and the connecting port 205-3 is connected to the water receiving box 5; the extension part 205-2 serves as an expansion part of the cabinet, and its purpose is to cooperate with the filter nozzle 601 of the filter assembly 6 to receive the grease collected by the filter assembly 6. Its structure is simple and reasonable, and the product integrity is stronger.

[0033] When the water receiving box 5 is installed in the cabinet 205, a baffle 502 is provided on the water receiving box 5 between the opening 204 and the connecting port 205-3. The baffle 502 divides the water receiving box 5 into an air guide area 503 and an oil dripping area 504. A conducting gap 505 is provided between the bottom of the baffle 502 and the bottom surface of the water receiving box 5. The baffle 502 can make the smoke entering the opening 204 contact the water faster and then be discharged from the air outlet 501.

[0034] Two support plates 101 extend from both sides of the base 1, and the two sides of the host 2 are movably connected to the two support plates 101 through a rotating head 206, so that the host 2 can rotate relative to the base 1; this facilitates the host function to be close to the source of oil smoke, which is conducive to faster smoking.

[0035] The water receiving box 5 is provided with a door panel 506 which cooperates with the installation inlet 205-1, and the air outlet 501 is arranged at the upper part of the door panel 506; the reason why the air outlet 501 is not arranged at the lower part or the lower half of the door panel 506 is that the water receiving box needs to store a certain amount of water, so the water receiving box must maintain air circulation, specifically discharged through the air outlet 501, and ensure a certain amount of water storage, so the air outlet 501 must be arranged at the upper part or the upper half of the door panel 506.

[0036] A handle 507 extends from the door panel 506 ; for easy operation, the consumer can pull out the water receiving box 5 in the form of a drawer through the handle 507 , making it easy to disassemble and assemble the water receiving box 5 .

[0037] A heat dissipation port 207 is provided on one side of the motor cavity 202 ; the heat dissipation port 207 facilitates heat dissipation of the motor 3 and maintains the motor 3 in a good working condition.

[0038] The filter assembly 6 includes an outer frame 602, an oil fume separation net 603 and a filter net 604. The outer frame 602 is in the shape of a hollow frame. A front wall plate 602a is provided at the front end of the outer frame 602. A mounting through hole 602b is provided on the front wall plate 602a. A side wall plate 602c extends from the inner side of the front wall plate 602a toward the direction of the motor 3. The bottom end of the side wall plate 602c and the mounting through hole 602b form a limiting portion 602d. A plurality of notches 602e are provided in the front wall plate 602a in a circumferential direction. A buckle is provided in each notch 602e. The buckle includes a first buckle 602f and a second buckle 602g of different lengths. 603 is installed in the installation through hole 602b and fixed by the first buckle 602f, and the front end of the oil fume separation net 603 is limited by the limiting part 602d, and the filter net 604 is tightly attached to the rear end of the oil fume separation net 603 and fixed by the first buckle 602g; the first buckle 602f and the second buckle 602g of different lengths can realize the separate buckle fixation of the oil fume separation net 603 and the filter net 604, which is specifically achieved by the barb on each buckle. The design is ingenious and easy to disassemble and clean. Multiple filter cottons or filter nets can also be added between the oil fume separation net 603 and the filter net 604 for clamping to improve the filtering effect.

[0039] The filter mesh oil nozzle 601 is provided on the outer frame 602, and an oil leakage notch 602h is provided on the side wall plate 602c. The oil leakage notch 602h is arranged corresponding to the filter mesh oil nozzle 601, so that the grease filtered by the oil fume separation net 603 passes through the oil leakage notch 602h and flows from the filter mesh oil nozzle 601 to the water receiving box 5; the design is ingenious, the oil filtering effect is good, and the grease flow path is short, which can achieve the purpose of rapid oil collection.

[0040] In addition, the combination of the outer frame 602, the front wall plate 602a and the side wall plate 602c effectively improves the structural strength of the filter assembly 6, and can ensure that it does not deform during multiple disassembly, assembly and cleaning processes.

[0041] like Figure 5 As shown, the oil smoke intercepting bodies on two adjacent layers of filter grilles at least partially overlap inside and outside; this structure can ensure that the oil smoke cannot pass through the filter screen 2 in a straight line, so that the oil smoke must pass through a circuitous filtering path, and at least partially overlap inside and outside, so that the filter screen can form a complete plane when viewed horizontally;

[0042] In this embodiment, the specific structure of the oil fume separation net 603 also includes a supporting outer frame 603a, and the supporting outer frame 603a is provided with a first filter grille 603b, a second filter grille 603c and a third filter grille 603d from the inside to the outside;

[0043] The first filter grille 603b and the third filter grille 603d are arranged in a symmetric arc shape. The convex arc surface of the third filter grille 603d faces the inflow of the air flow. A first climbing entrance 603e is provided between the third filter grille 603d and the second filter grille 603c. At the same time, a second climbing entrance 603f is provided on the second filter grille 603c. A third climbing entrance 603g is provided between the first filter grille 603b and the second filter grille 603c. The first climbing entrance 603e, the second climbing entrance 603f, and the third climbing entrance 603g form a circuitous path for the air flow to pass through the oil fume separation net 603, effectively achieving the effect of filtering grease.

[0044] The filter grille of this structure forms a circuitous filtration path through a staggered arrangement method. The circuitous filtration path can reduce the speed of the oil fume being discharged, increase the contact time between the oil fume and the surface of the filter grille, and enable the grease in the oil fume to stay on the filter grille due to collision or interception, improving the filtration efficiency of the oil fume.

[0045] Working principle: The oil fume enters through the smoke suction air inlet 201 and passes through the filter net assembly 6. Due to gravity, the grease drops downward and enters the oil dripping area 504 of the water receiving box 5 through the filter net oil nozzle 601 and the connection port 205-3. The flue gas is guided by the wind wheel 4 (a centrifugal wind wheel can be selected), is thrown out from the side of the wind wheel 4 and enters the air guiding area 503 of the water receiving box through the opening 204. After the flue gas contacts the water in the water receiving box, it is absorbed, and the smokeless gas is finally discharged from the air outlet 501, forming a gas that is invisible to the naked eye.

[0046] Second embodiment:

[0047] As Figure 7 shown, two layers of air filter nets 7 are arranged in the water receiving box 5 between the opening 204 and the air outlet 501. The air filter nets 7 are separable relative to the water receiving box 5, and the two layers of air filter nets 7 are arranged at intervals; the air filter nets are used to eliminate the smoke after the oil fume enters the water receiving box 5 and contacts the stored water, and are filtered by the air filter nets 7 before passing through the air outlet 501, further achieving the effects of deodorization and grease filtration, making the air discharged from the air outlet 501 cleaner and fresher.

[0048] Insertion slots suitable for the detachable installation of the air filter nets 7 are provided on the side walls on both sides of the water receiving box 5. Each insertion slot is formed by two connecting blocks 8 arranged at intervals.

[0049] A filter cotton 9 is added between the oil fume separation net 603 and the filter net 604 for clamping to improve the filtering effect.

[0050] The above is the preferred embodiment of the present invention, which shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
