Description

TECHNICAL FIELD

[0001] The utility model relates to a stove, especially a single-fan adjustable electric flame stove. BACKGROUND

[0002] As a new stove product, the electric flame stove is gradually attracting market attention due to its environmental protection and safety. This stove forms plasma in the air through high-voltage discharge, and then generates high-temperature heating to achieve cooking function. It is an innovative stove solution that does not rely on gas.

[0003] In the current market, the electric flame stove product, the firepower adjusting function is the important demand in the daily use of the user. However, the existing electric flame stove firepower adjusting mode is relatively single, mainly relies on the adjusting switch to change the discharge current. Specifically, when the user needs to increase or decrease the firepower, the current intensity can only be changed by operating the adjusting switch, and the change of the current intensity directly affects the discharge intensity, so as to achieve the purpose of adjusting the firepower. This adjusting mode has a significant limitation, that is, it can only adjust all discharge electrodes of the stove as a whole. In other words, when the user adjusts the firepower, the discharge intensity of all discharge electrodes will change at the same time, and independent control of the discharge intensity of different regions cannot be achieved. The characteristics of this overall adjustment make the electric flame stove lack flexibility in actual use. SUMMARY

[0072] The single-fan adjustable electric flame stove is described in detail below with reference to the drawings.

[0073] Referring to Figures 1 to 5 As shown in the figure, the single-fan adjustable electric flame stove provided by the utility model embodiment comprises a stove base 10, a panel 20, an electric flame stove 30, a control element 40 and a fan 50.

[0074] Specifically, the stove base 10 can be made of high-temperature-resistant metal material, such as stainless steel material, etc., and has good stability and heat dissipation performance. The stove base 10 can be placed on a kitchen stove top surface, a desktop surface or other planar carrier.

[0075] The panel 20 is arranged on the stove base 10, and a stove hole is arranged on the panel 20. The panel 20 can be made of stainless steel or tempered glass, etc., and has high structural strength and is convenient to clean and maintain. The stove hole is used for mounting the electric flame stove 30, and the shape of the stove hole can be a circular shape or other shape, which can be matched with the electric flame stove 30.

[0076] The electric flame stove 30 comprises a stove head 301 and a stove base 302. The stove head 301 is hung in the stove hole and at least partially located above the panel 20. The stove head 301 has a first electrode group and a second electrode group. Each first discharge electrode 3011 of the first electrode group is located in the middle of the stove head 301. Each second discharge electrode 3012 of the second electrode group is arranged around the first electrode group in a concentric circle manner. That is, the first electrode group is located in the central region of the stove head 301 and comprises a plurality of uniformly distributed first discharge electrodes 3011, forming a central heating region. The plurality of second discharge electrodes 3012 of the second electrode group are arranged around the first electrode group in a concentric circle manner, forming a peripheral heating region.

[0077] The furnace base 302 is located in the cooktop 10 and connected to the bottom of the furnace head 301, and the first air cavity P30a and the second air cavity P30b are formed in the furnace base 302, the first air cavity P30a is communicated with each first discharge electrode 3011 in the first electrode group, and the second air cavity P30b is communicated with each second discharge electrode 3012 in the second electrode group.

[0078] It can be understood that the first discharge electrode 3011 and the second discharge electrode 3012 generally each include a positive electrode and a negative electrode, and the negative electrode is generally in a sleeve structure, and the positive electrode is located inside the sleeve structure. Since the sleeve structure is a hollow structure, it can be communicated with the first air cavity P30a or the second air cavity P30b, and then air can be supplied to the first discharge electrode 3011 and the second discharge electrode 3012.

[0079] The control knob 40 is arranged on the cooktop 10 and is used for the user to operate to switch the second air cavity P30b to be communicated with or blocked from the first air cavity P30a. That is, the first air cavity P30a and the second air cavity P30b are two independent cavities, and the control knob 40 can control whether the second air cavity P30b is communicated with the first air cavity P30a.

[0080] The fan 50 is communicated with the first air cavity P30a and is used to supply air to the first air cavity P30a, so that the air flow enters the first electrode group through the first air cavity P30a, or the air flow enters the first electrode group through the first air cavity P30a, and at the same time, enters the second air cavity P30b through the first air cavity P30a, and then enters the second electrode group through the second air cavity P30b.

[0081] In use, when the small fire mode is needed, the user can use the control knob 40 to control the second air cavity P30b to be blocked from the first air cavity P30a, at this time, the air flow generated by the fan 50 can only enter the first air cavity P30a, and cannot flow into the second air cavity P30b. After the electric flame stove is started, the first discharge electrode 3011 generates an electric flame, and a relatively concentrated discharge heating area is formed in the central area, which is suitable for small pot heating or slow cooking and other cooking scenes.

[0082] When the large fire mode is needed, the user can control the second air cavity P30b to communicate with the first air cavity P30a through the control device 40, at this time, when the air flow enters the first air cavity P30a, on one hand, it directly enters the first discharge electrode 3011, and on the other hand, the air flow enters the second air cavity P30b from the first air cavity P30a, and then enters the second discharge electrode 3012 through the second air cavity P30b, in this way, the inner and outer large-area uniform heating areas are formed, which are suitable for large pots or rapid heating scenes.

[0083] Preferably, the fan 50 is a variable frequency speed regulation fan 50, which can accurately adjust the speed through the controller, thereby realizing accurate control of the air supply amount.

[0084] According to the single-fan adjustable electric flame stove provided in the embodiment of the utility model, a single fan 50 is adopted to cooperate with the design of double air cavities, the first air cavity P30a and the second air cavity P30b are arranged in the stove base 302, and the control device 40 is arranged on the stove base 10, thereby realizing the air flow distribution control of the inner and outer two heating areas. When the control device 40 is in the communication state, the air flow generated by the fan 50 can enter the first electrode group and the second electrode group through the first air cavity P30a and the second air cavity P30b at the same time, thereby realizing the inner and outer area fire heating. When the control device 40 is switched to the blocking state, the air flow only enters the middle first electrode group through the first air cavity P30a, thereby realizing the small-area concentrated heating. This design not only breaks through the limitation that the traditional electric flame stove can only be adjusted as a whole, but also realizes the selective control of the double areas by using only one fan 50, thereby reducing the product cost, providing a more flexible fire control mode selection, and significantly improving the practicability and user experience of the electric flame stove.

[0085] In some embodiments of the utility model, the stove base 302 includes a wind pipe 3021 and a pivot sleeve 3022, the upper end of the wind pipe 3021 is installed at the bottom of the stove head 301, preferably, the upper end of the wind pipe 3021 is detachably connected with the bottom of the stove head 301. The first air cavity P30a and the second air cavity P30b are formed in the wind pipe 3021, and the second air cavity P30b surrounds the outside of the first air cavity P30a and forms an annular structure, and a communication port H30a is arranged between the first air cavity P30a and the second air cavity P30b. That is, the first air cavity P30a is a cylindrical cavity, the second air cavity P30b is an annular cavity, the annular cavity surrounds the outside of the cylindrical cavity, and the coaxial arrangement is formed, at the same time, the first air cavity P30a and the second air cavity P30b are independent of each other and can be communicated through the communication port H30a, for example, the communication port H30a is arranged on the peripheral wall of the first air cavity P30a, thereby enabling the air flow in the first air cavity P30a to enter the second air cavity P30b through the communication port H30a on the peripheral wall.

[0086] The pivot sleeve 3022 is arranged in the air duct 3021 and rotatable about the axis of the air duct 3021 between a first position and a second position. Preferably, the outer diameter of the pivot sleeve 3022 is adapted to the diameter of the first air cavity P30a, and the pivot sleeve 3022 is fitted into the first air cavity P30a to be in abutment with the peripheral wall of the first air cavity P30a. When the pivot sleeve 3022 is in the first position, the pivot sleeve 3022 blocks the communication port H30a to block the second air cavity P30b from the first air cavity P30a, and when the pivot sleeve 3022 is in the second position, the pivot sleeve 3022 opens the communication port H30a to make the second air cavity P30b communicate with the first air cavity P30a.

[0087] The control member is connected with the pivot sleeve 3022 to drive the pivot sleeve 3022 to rotate between the first position and the second position.

[0088] In use, the user can control the position of the pivot sleeve 3022 by rotating the operating handle to open or close the air flow passage between the second air cavity P30b and the first air cavity P30a. When small fire power is needed, the operating handle is turned to the first position, at which time the pivot sleeve 3022 blocks the communication port H30a, and the air flow in the first air cavity P30a cannot enter the second air cavity P30b, and the air flow can only enter the first electrode group on the burner head 301 through the first air cavity P30a to realize central area heating. When large fire power is needed, the operating handle is turned to the second position, at which time the pivot sleeve 3022 opens the communication port H30a, and the second air cavity P30b communicates with the first air cavity P30a, and the air flow can enter the first air cavity P30a and the second air cavity P30b to realize large-area and uniform heating of the inner and outer areas.

[0089] In the embodiment, the combination of the pivot sleeve 3022 and the air duct 3021 is adopted to realize reliable switching of the communication state between the second air cavity P30b and the first air cavity P30a, which is simple in structure and convenient to operate, and only needs to drive the pivot sleeve 3022 to rotate by a certain angle through the control member to realize partitioned fire power control.

[0090] In an embodiment of the present application, the air duct 3021 comprises an inner cylinder 3021a and an outer cylinder 3021b, the inner space of the inner cylinder 3021a defines the first air cavity P30a, and the outer cylinder 3021b is arranged outside the inner cylinder 3021a and defines the second air cavity P30b with the inner cylinder 3021a.

[0091] The communication ports H30a are multiple, and the multiple communication ports H30a are arranged on the peripheral wall of the inner cylinder 3021a and are arranged in a circumferential direction; the pivoting sleeve 3022 is sleeved in the inner cylinder 3021a, and the peripheral wall of the pivoting sleeve 3022 is provided with multiple air vents H30b, and the multiple air vents H30b correspond to the multiple communication ports H30a one by one.

[0092] When the pivoting sleeve 3022 is located at the first position, the air vents H30b are misaligned with the communication ports H30a, so that the communication ports H30a are closed; when the pivoting sleeve 3022 is located at the second position, the air vents H30b are opposite to the communication ports H30a and are in communication, so that the communication ports H30a are opened.

[0093] In this embodiment, the air cylinder 3021 adopts a double-cylinder structure design, including an inner cylinder 3021a and an outer cylinder 3021b. The inner cylinder 3021a is in a cylindrical shape, and the hollow region inside the inner cylinder 3021a constitutes a first air chamber P30a. Multiple communication ports H30a are uniformly arranged on the peripheral wall of the inner cylinder 3021a in a circumferential direction. The inner diameter of the outer cylinder 3021b is larger than the outer diameter of the inner cylinder 3021a, and the outer cylinder 3021b is arranged concentrically with the inner cylinder 3021a. The annular space between the outer cylinder 3021b and the inner cylinder 3021a constitutes a second air chamber P30b. The outer cylinder 3021b and the inner cylinder 3021a can be detachably connected, which facilitates assembly.

[0094] The outer diameter of the pivoting sleeve 3022 matches the inner diameter of the inner cylinder 3021a. Multiple air vents H30b are arranged on the peripheral wall of the pivoting sleeve 3022, and the positions of the air vents H30b correspond to the positions of the communication ports H30a on the inner cylinder 3021a one by one. The size of the air vents H30b can be slightly larger than the size of the communication ports H30a, so as to ensure that sufficient ventilation area can be obtained when the air vents H30b are aligned with the communication ports H30a.

[0095] In a working state, when the pivoting sleeve 3022 is located at the first position, the air vents H30b are offset from the communication ports H30a by a certain angle, for example, 45°. The solid wall of the pivoting sleeve 3022 completely covers the communication ports H30a, thereby blocking the airflow passage between the first air chamber P30a and the second air chamber P30b. When the control member drives the pivoting sleeve 3022 to rotate to the second position, the air vents H30b are aligned with the communication ports H30a, forming multiple uniformly distributed airflow passages, allowing the airflow in the first air chamber P30a to enter the second air chamber P30b.

[0096] In this embodiment, the inner and outer double-cylinder structure cooperates with the rotatable pivoting sleeve 3022, the double-cylinder structure provides stable and reliable air chamber separation, and facilitates processing and assembly. The multiple uniformly distributed communication ports H30a and air vents H30b ensure the uniformity of airflow distribution.

[0097] In an embodiment of the utility model, the lower end of inner cylinder 3021a is protruded downward to form lower neck part 3021c, which is overall cylindrical and coaxially arranged with inner cylinder 3021a. Lower neck part 3021c is provided with opening H30d for the installation of control member.

[0098] Hearth 302 further comprises bottom plate 3023, which is fixedly sealed on the lower end face of lower neck part 3021c to confine pivot sleeve 3022 within inner cylinder 3021a, and control member is connected with pivot sleeve 3022 through opening H30d to drive the rotation of pivot sleeve 3022. Bottom plate 3023 can be made of metal material such as stainless steel plate, which is overall disc-shaped, with diameter matching the outer diameter of lower neck part 3021c, and is fixed on the end face of lower neck part 3021c by screws. Annular sealing groove can be provided on the mating surface of bottom plate 3023 and lower neck part 3021c, and sealing ring such as fluorine rubber O-ring can be embedded in the annular sealing groove to ensure the sealing effect.

[0099] The present embodiment forms a compact, easy-to-install and easy-to-maintain hearth 302 through the design of lower neck part 3021c, bottom plate 3023 and control member. Lower neck part 3021c provides reliable installation space for control member, the detachable structure of bottom plate 3023 facilitates product assembly and maintenance, and control member ensures the convenience of operation.

[0100] In an embodiment of the utility model, the outer peripheral surface of the lower end of pivot sleeve 3022 has ear part 3022a, which extends out of opening H30d. That is, the position of ear part 3022a corresponds to the position of opening H30d of lower neck part 3021c, and extends outwards through the opening H30d. In addition, the width dimension of opening H30d is greater than that of ear part 3022a, so that ear part 3022a swings within opening H30d when pivot sleeve 3022 rotates relative to inner cylinder 3021a.

[0101] Control member comprises rod part 401 and operation part 402, one end of rod part 401 extends into cooktop seat 10 and is connected with ear part 3022a, and operation part 402 is arranged on the other end of rod part 401 and located outside cooktop seat 10 for user operation. Preferably, the other end of rod part 401 extends out of the front side of cooktop seat 10, and operation part 402 is exposed on the front side, thereby facilitating user operation.
