Description

Technical Field

[0001] The present invention relates to a steam multi-purpose furnace.

Background Art

[0002] Among the cooking utensils with steam function on the market, generally having heating function and steam function, they can be used for multiple purposes. For example, through the heating function, food can be cooked, baked, and also used for hot pot, etc., and through the steam function, food can be steamed. For some of the existing such cooking utensils, the generation of steam is achieved by pumping water with a water pump and then through a steam generator. Such cooking utensils have a relatively high cost for steam generation. There is also a type that generates steam by heating water with the temperature of the furnace body. For example, the patent number is 201120090934.0, and the name is a steam baking oven with an inserted thermostat. Its water tank is communicated with the steam pipeline inside the baking plate through a nozzle. After water enters from one end of the steam pipeline, it enters the baking plate to be heated to generate steam, and the steam flows out from the steam plug at the other end of the steam pipeline. In this way, the generation of steam is relatively slow, with low efficiency and insufficient steam volume.

Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a water-drop type steam multi-purpose furnace with low production cost and capable of quickly generating sufficient steam.

[0004] To solve the above problems, the present invention adopts the following technical solutions:

[0005] A water-drop type steam multi-purpose furnace, including a base, a heating plate is provided on the base, a heater capable of heating the heating plate is provided on the heating plate, a heating cavity with an open upper end and a material tray for placing foodstuffs covering the opening of the heating cavity are provided inside the heating plate. It is characterized in that: a water tank housing is provided inside the heating cavity, a suspended water tank is provided inside the water tank housing, a plurality of water dripping holes for dripping water into the heating cavity to form steam are provided inside the water tank, and a steam switch assembly capable of controlling the opening and closing of the water dripping holes is provided on the water tank housing.

[0006] The water-drop type steam multi-purpose furnace as described above is characterized in that: the steam switch assembly includes a linkage frame provided on the water tank housing and capable of being inserted into the water tank, a plurality of plugs capable of blocking the water dripping holes are provided on the linkage frame, and a bimetallic strip capable of driving the linkage frame to open the water dripping holes after being heated is provided on the water tank housing.

[0007] A water-drop type steam multi-functional stove as described above, characterized in that: an installation boss is arranged in the heating cavity, a positioning groove is arranged on the installation boss, a bottom shell is arranged at one end of the water tank shell, and a positioning hole for the bimetal sheet to expose and abut against the positioning groove is arranged on the bottom shell, and a linkage column is arranged on the linkage frame, one end of which abuts against the bimetal sheet and can be lifted when the bimetal sheet deforms.

[0008] A water-drop type steam multi-functional stove as described above, characterized in that: a guide hole for the linkage column to extend into is arranged on the water tank shell.

[0009] A water-drop type steam multi-functional stove as described above, characterized in that: two water tanks are arranged relatively spaced apart, two bifurcated sheets respectively inserted into the two water tanks are arranged on the linkage frame, and the plug is arranged on the bifurcated sheet.

[0010] A water-drop type steam multi-functional stove as described above, characterized in that: a limit hole communicating with the water tank and for the bifurcated sheet to be inserted and limiting the height of the bifurcated sheet is arranged on the water tank shell.

[0011] A water-drop type steam multi-functional stove as described above, characterized in that: guide grooves are arranged on the bottom surface of the material tray in a relatively spaced-apart manner, and both sides of the water tank shell are slidably inserted into the guide grooves.

[0012] A water-drop type steam multi-functional stove as described above, characterized in that: an installation cavity with an open upper end is arranged on the base, a positioning step pressing against the installation cavity is arranged on the heating plate, the lower end of the heating plate extends into the installation cavity, a food cavity is formed by the part of the heating plate above the positioning step extending upward, the material tray is arranged on the upper end surface of the positioning step and separates the food cavity and the heating cavity, convection holes for steam or heat to convect from the heating cavity to the food cavity are arranged on the material tray, and the heater is arranged outside the bottom wall of the heating plate.

[0013] The beneficial effects of the present invention are as follows: After the heater is started, the heating chamber is heated to a high temperature. After the steam switch assembly is opened, water drips from the water tank into the heating chamber in the form of water droplets. In this way, the amount of water heated instantaneously is small, and steam can be generated quickly. Through the distribution of multiple water dripping holes, the contact area between the water droplets and the bottom wall of the heating chamber can be increased, so as to rapidly generate a sufficient amount of steam. By using a bimetal sheet, after the heating plate is heated, heat is conducted to the bimetal sheet. The bimetal sheet generates a bending deformation when heated. Under the action of the bending deformation, the linkage frame is gradually lifted. In this way, the larger the opening amount of the water dripping hole, the faster the water droplets fall. When the heating plate descends due to the water droplets, the bimetal dry burning sheet restores its deformation, so that the linkage frame gradually descends, the opening of the water dripping hole gradually becomes smaller, and the amount of dripping water becomes smaller. This ensures the rapid generation of steam and prevents water from accumulating in the heating chamber. The water tank housing is arranged on the material tray in a pull-out manner. In this way, when the steam function is not needed, the water tank housing can be pulled out for use in baking food, cooking food, hot pot, etc., which is convenient to use.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be further described in detail below in conjunction with the drawings and the specific embodiments:

[0018] As Figures 1 to 3As shown in the figure, a water-drop type multi-functional steam stove includes a base 1. In this embodiment, the base 1 is a square disc-shaped one. A heating plate 2 is provided on the base 1. The heating plate 2 is supported by the base 1, and the bottom wall of the heating plate 2 is spaced apart from the bottom wall of the base 1. A heater 10 capable of heating the heating plate 2 is provided on the heating plate 2. The heater 10 can be in the form of a PCT heater, a dry-burning tube, etc. A heating cavity 21 with an open upper end is provided in the heating plate 2, and a material tray 3 for placing food materials is covered on the opening of the heating cavity 21. The food to be made is placed on the material tray 3 for heating. The heater 10 heats the bottom wall of the heating cavity 21, and the temperature in the heating cavity 21 rises. A water tank housing 4 is provided in the heating cavity 21. A water tank 41 suspended in the heating cavity 21 is provided in the water tank housing 4. The water tank 41 is suspended, preventing water from directly contacting the inner wall of the heating cavity 21. A plurality of water dripping holes 42 for allowing water droplets to drop into the heating cavity 21 to form steam are provided in the water tank 41. When water flows down from the water dripping holes 42, it drops onto the bottom wall of the heating cavity 21, and the water droplets are quickly heated and turn into steam. A steam switch assembly 5 capable of controlling the opening and closing of the water dripping holes 42 is provided on the water tank housing 4. When the steam function is required, the steam switch assembly 5 can control the opening of the water dripping holes 42 to allow water droplets to drop.

[0019] In order to further achieve the on-off control of the water dripping holes 42, the steam switch assembly 5 includes a linkage frame 51 provided on the water tank housing 4 and capable of being inserted into the water tank 41. One end of the linkage frame 51 is inserted into the water tank 41. A plurality of plugs 52 capable of blocking the water dripping holes 42 are provided on the linkage frame 51. The plugs 52 are provided on the part inserted into the water tank 41. A bimetal sheet 53 is provided on the water tank housing 4, which can drive the linkage frame 51 to open the water dripping holes 42 after being heated. After the linkage frame 51 is driven, the plugs 52 move away from the water dripping holes 42, thereby opening the water dripping holes 42. An installation boss 22 is provided in the heating cavity 21. A positioning groove 23 is provided on the installation boss 22. One end of the water tank housing 4 is provided with a bottom case 43. A positioning hole 44 for the bimetal sheet 53 to expose and abut against the positioning groove 23 is provided on the bottom case 43. The bimetal sheet 53 is in an arc shape, and the bottom surface extends out from the positioning hole 44 and abuts against the positioning groove 23. In this way, after the heating plate 2 is heated, the installation boss 22 can quickly conduct heat to the bimetal sheet 53, causing the bimetal sheet 53 to bend and deform due to heat. A linkage column 46 is provided on the linkage frame 51, with one end pressing against the bimetal sheet 53 and capable of being lifted by the deformation of the bimetal sheet 53. The linkage column 46 is vertically arranged and provided at one end of the linkage frame 51 outside the water tank 41. After the bimetal sheet 53 is heated and bent, it lifts the linkage column 46 when deforming, thereby driving the entire linkage frame 51 to rise. A guiding hole 47 for the linkage column 46 to extend into is provided on the water tank housing 4. When the linkage column 46 rises and falls, it passes through the guiding hole 47, and the lifting is stable. In this embodiment, there are three sets of the linkage column 46, bimetal sheet 53, positioning groove 23, and positioning hole 44 in one-to-one correspondence. Two water tanks 41 are relatively spaced apart. Two bifurcated pieces 54 respectively inserted into the two water tanks 41 are provided on the linkage frame 51. The plugs 52 are provided on the bifurcated pieces 54. The water dripping holes 42 are arranged along the length direction of the water tank 41, and the plugs 52 are arranged along the length direction of the bifurcated pieces 54. A limiting hole 45 communicating with the water tank 41 and for the bifurcated pieces 54 to be inserted and restricting the height of the bifurcated pieces 54 is provided on the water tank housing 4. The bifurcated pieces 54 pass through the limiting hole 45 and into the water tank 41. The height of the bifurcated pieces 54 is restricted by the height of the limiting hole 45, preventing the linkage frame 51 from rising too high, and thus preventing the amount of water in the water dripping holes 42 from being too large.

[0020] In order to facilitate the installation of the oven and make the structure more reasonable, an installation cavity 11 with an open upper end is provided on the base 1. A positioning step 24 pressing against the installation cavity 11 is provided on the heating plate 2. The lower end of the heating plate 2 extends into the installation cavity 11. The part of the heating plate 2 above the positioning step 24 extends upward to form a food cavity 25. The size of the food cavity 25 is larger than the opening size of the installation cavity 11. The material tray 3 is provided on the upper end surface of the positioning step 24 and separates the food cavity 25 and the heating cavity 21. The material tray 3 is provided with convection holes 31 for steam or heat to convect from the heating cavity 21 to the food cavity 25. The heater 10 is provided outside the bottom wall of the heating plate 2, and food is placed above the material tray 3.
