Description

Technical Field

[0001] This utility model relates to the field of ovens, and in particular to a smoking oven. Background Technology

[0002] A smoke oven is a kitchen appliance that combines traditional baking with unique smoking functions. It uses low-temperature, slow baking and smoking to allow food to absorb the smoke from the smoke-producing ingredients, creating a unique flavor and texture. Most existing smoke ovens on the market use a separate heating element to heat the smoke-producing ingredients, generating smoke, which is then directed into the oven's cooking chamber.

[0003] For example, Chinese invention application CN120267155A discloses a smoking oven, including a smoking component, an inner liner, and a cabinet. The smoking component and the inner liner are located inside the cabinet. One side of the cabinet has a door, a material inlet, and a water tank outlet. The inner liner has a cooking opening near the door and a smoke outlet near the smoking component. The smoking component includes a material cylinder, a feeder, a heater, a flue, and a water tank cavity. The feeder is located below the material cylinder and contains a quantitative feeding device. Below the feeder is the heater, and below the heater is the water tank cavity containing a water tank. The flue covers the water tank cavity and connects the water tank cavity to the smoke outlet. This smoking oven uses different heaters to heat the food and smoking materials separately, resulting in high production costs. Furthermore, controlling the amount of smoke produced by the smoking materials by adjusting the temperature of the heater used to heat the materials makes its structure complex and operation cumbersome.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a smoking oven that eliminates the need for a separate heating element to heat the smoking material. The amount of smoke can be controlled by adjusting the distance between the smoking material box and the first heating element. The oven has a simple structure and is easy to operate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a smoking oven, including a box having a cooking chamber and a smoking spice box, wherein a first heating element is provided in the cooking chamber; the smoking spice box is located in the cooking chamber and is correspondingly located below the first heating element; it also includes a lifting mechanism for driving the smoking spice box to move up and down so that the smoking spice box approaches or moves away from the first heating element.

[0007] The heat radiation from the first heating element heats the incense material inside the incense box, producing smoke to achieve the smoking effect. When the incense box is close to the first heating element, the incense material is heated to a higher temperature, which increases the rate of smoke production and the amount of smoke; when the incense box is far from the first heating element, the incense material is heated to a lower temperature, which decreases the rate of smoke production and the amount of smoke.

[0008] The first heating element heats both the food in the cooking chamber and the smoking material in the smoking box simultaneously, eliminating the need for a separate heating element for the smoking material and thus reducing production costs. The amount of smoke can be controlled by moving the smoking box closer to or away from the first heating element via a lifting mechanism; the structure is simple and easy to operate.

[0009] According to the above scheme, the lifting mechanism includes a lifting support plate and a lifting drive assembly. The lifting support plate is used to support the smoke box, and the lifting drive assembly is used to drive the lifting support plate to move up and down.

[0010] The smoke box tends to move downwards under its own weight, thus being supported by a lifting support plate. The lifting drive assembly moves the lifting support plate up and down, thereby causing the smoke box to move up and down synchronously.

[0011] In some embodiments, the first heating element is disposed at the lower part of the cooking chamber, the housing has a bottom plate with an opening on the bottom plate; the lifting support plate includes a first step portion and two second steps portions protruding through the opening, the first step portion is used to support the smoking spice box, and the two steps portions are symmetrically connected to the two ends of the first step portion and located below the bottom plate; when the lifting drive assembly drives the first step portion to the highest position, the second steps portion abuts against the bottom surface of the bottom plate.

[0012] By setting a second step, the upward movement of the lifting support plate can be limited, thereby preventing the lifting support plate from colliding with the first heating element when it moves upward.

[0013] According to the above scheme, a guide groove is fixed on the bottom surface of the base plate, and the guide groove is connected to the opening; the second step is movably disposed in the guide groove, and a guide plate that contacts the inner sidewall of the guide groove is provided on the second step.

[0014] By setting up mutually cooperating guide plates and guide grooves, the lifting support plate can move up and down smoothly, thereby improving the stability of the smoke box's up and down movement.

[0015] According to the above scheme, the lifting drive assembly includes a U-shaped rod and a control mechanism. The two ends of the U-shaped rod are rotatably connected to the guide groove. The U-shaped rod is located below the first step. The protruding part in the middle of the U-shaped rod is used to support the first step. The control mechanism is used to drive the U-shaped rod to rotate.

[0016] The lifting support plate, under its own weight and that of the fumigation box, tends to move downwards, causing the first step to be supported by the central protrusion of the Z-shaped rod. The control mechanism drives the Z-shaped rod to rotate, causing the vertical height of the central protrusion of the Z-shaped rod to change, thereby moving the first step up and down.

[0017] According to the above scheme, the control mechanism includes a control lever and a toggle key. The control lever is fixedly connected to one end of the U-shaped rod, and the toggle key is kinetically connected to the control lever. The user toggles the toggle key to control the rotation of the U-shaped rod via the control lever.

[0018] It is understood that, in some embodiments, those skilled in the art may employ control mechanisms with other structures as needed. For example, in some embodiments, the control mechanism includes a knob, which is fixedly connected to one end of the U-shaped rod; the user can rotate the knob to drive the U-shaped rod to rotate. As another example, in some embodiments, the control mechanism includes a rotary motor, the output shaft of which is fixedly connected to one end of the U-shaped rod; controlling the rotation of the rotary motor can drive the U-shaped rod to rotate.

[0019] In some embodiments, a detachable slag-receiving tray is further included in the cooking chamber, and the first heating element is located in the lower part of the cooking chamber; the slag-receiving tray is provided with a placement hole, and the smoking material box is movably disposed in the placement hole; the outer periphery of the smoking material box is provided with a flange, and the flange is located above the slag-receiving tray.

[0020] When the slag tray is removed from the cooking chamber, the flange of the smoking seasoning box abuts against the slag tray to prevent the smoking seasoning box from falling out of the placement hole, so that the smoking seasoning box can be removed from the cooking chamber along with the slag tray, making it convenient to add smoking seasoning and clean the smoking seasoning box.

[0021] In some embodiments, a second heating element and a steam device are also included, the second heating element and the first heating element being respectively disposed in the upper and lower parts of the cooking chamber; the steam device includes a water tank and a water supply mechanism, the water supply mechanism being used to supply water to the water tank, the water tank being disposed above the second heating element.

[0022] The downward heat radiation from the second heating element and the upward heat radiation from the first heating element can simultaneously heat the food, improving the baking efficiency. The upward heat radiation from the second heating element can also heat the water in the upper tank to generate steam, effectively utilizing the heat from the second heating element.

[0023] In some embodiments, a third heating element and a steam device are also included, wherein the third heating element and the first heating element are both located in the lower part of the cooking chamber; the steam device includes a water tank and a water supply mechanism, wherein the water supply mechanism is used to supply water to the water tank, and the water tank is located below the third heating element.

[0024] The upward heat radiation from the first and third heating elements can simultaneously heat the food, improving the baking efficiency; the downward heat radiation from the third heating element heats the water in the tank to generate steam, effectively utilizing the heat from the third heating element.

[0025] In some embodiments, those skilled in the art may, according to actual needs, configure a cooking chamber with a first heating element, a second heating element, and a third heating element. The first heating element and the third heating element are both located in the lower part of the cooking chamber, and the second heating element is located in the upper part of the cooking chamber. The downward heat radiation from the second heating element and the upward heat radiation from the first and third heating elements can simultaneously heat the food; the downward heat radiation from the third heating element heats the water in the water tank.

[0026] By setting up a water tank and water supply system, steam can be added to the food during the smoking and roasting process. This prevents the food surface from dehydrating too quickly and forming a membrane during the high-temperature smoking process, thereby accelerating the penetration of smoke into the food and achieving better cooking results.

[0027] According to the above scheme, the water supply mechanism includes a water tank, a water pump, and a water outlet pipe connected in sequence via a connecting pipe. By controlling the operation of the water pump, water from the water tank can be pumped into the water tank.

[0028] According to the above scheme, the water supply mechanism also includes a water tank bracket, and the water tank is detachably installed on the water tank bracket; the water tank is provided with a one-way valve, and the water tank bracket is provided with a hollow push rod that communicates with the water pump, and the hollow push rod is used to trigger the one-way valve to open.

[0029] With the above structural design, when the water tank is installed on the water tank bracket, the hollow top rod triggers the one-way valve to open, allowing the water in the water tank to flow out sequentially through the one-way valve and the hollow top rod; and when the water tank is removed from the water tank bracket, the one-way valve closes, thus facilitating the addition of water to the water tank.

[0030] According to the above solution, a water level sensor is installed on the water tank support, which is used to sense the water level inside the water tank. When the water level sensor detects that the water level inside the tank is too low, it can notify the user to add water to the tank.

[0031] The beneficial effects of this utility model are as follows: 1. The first heating element heats both the food in the cooking chamber and the smoking material in the smoking material box simultaneously, eliminating the need for a separate heating element to heat the smoking material, which helps reduce production costs; 2. The amount of smoke can be controlled by moving the fumigation box closer to or away from the first heating element through the lifting mechanism. The structure is simple and easy to operate.

[0034] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments. Example

[0035] like Figure 1-6As shown, this utility model provides a smoke oven, including a box 1 with a cooking chamber 11 and a smoke box 3. The cooking chamber 11 is provided with a first heating element 2. The smoke box 3 is located in the cooking chamber 11 and is located below the first heating element 2. It also includes a lifting mechanism for driving the smoke box 3 to move up and down so that the smoke box approaches or moves away from the first heating element 2.

[0036] The first heating element 2 heats both the food in the cooking chamber 11 and the smoking material in the smoking material box 3 simultaneously, eliminating the need for a separate heating element for the smoking material and thus reducing production costs. The amount of smoke can be controlled by moving the smoking material box 3 closer to or further away from the first heating element 2 via a lifting mechanism; the structure is simple and easy to operate.

[0037] Furthermore, the lifting mechanism includes a lifting support plate 5 and a lifting drive assembly 6. The lifting support plate 5 is used to support the smoke box 3, and the lifting drive assembly 6 is used to drive the lifting support plate 5 to move up and down.

[0038] The fumigation box 3 tends to move downwards under its own weight, thus being supported by the lifting support plate 5. The lifting drive assembly 6 drives the lifting support plate 5 to move up and down, thereby causing the fumigation box 3 to move up and down synchronously.

[0039] Furthermore, the first heating element 2 is located at the lower part of the cooking chamber 11, and the housing 1 has a bottom plate 12 with an opening 121. The lifting support plate 5 includes a first step portion 51 and two second step portions 52 protruding through the opening 121. The first step portion 51 is used to support the smoking spice box 3, and the two step portions 52 are symmetrically connected to the two ends of the first step portion 51 and located below the bottom plate 12. When the lifting drive assembly 6 drives the first step portion 51 to the highest position, the second step portion 52 abuts against the bottom surface of the bottom plate 12.

[0040] By setting the second step 52, the upward movement of the lifting support plate 5 can be limited, thereby preventing the lifting support plate 5 from colliding with the first heating element 2 when it moves upward.

[0041] Furthermore, a guide groove 13 is fixed on the bottom surface of the base plate 12, and the guide groove 13 communicates with the opening 121; the second step portion 52 is movably disposed in the guide groove 13, and a guide plate 53 is provided on the second step portion 52 that contacts the inner sidewall of the guide groove 13. By setting up the guide plate 53 and guide groove 13 that cooperate with each other, the lifting support plate 5 can move up and down smoothly, thereby improving the stability of the smoke box 3 moving up and down.

[0042] Furthermore, the lifting drive assembly 6 includes a U-shaped rod 61 and a control mechanism. The two ends of the U-shaped rod 61 are rotatably connected to the guide groove 13. The U-shaped rod 61 is located below the first step portion 51. The protruding part 611 in the middle of the U-shaped rod 61 is used to support the first step portion 51. The control mechanism is used to drive the U-shaped rod 61 to rotate.

[0043] The lifting support plate 5, under its own weight and the weight of the fumigation box 3, tends to move downwards, causing the first step 51 to be supported by the central protrusion 611 of the U-shaped rod 61. The control mechanism drives the U-shaped rod 61 to rotate, causing the height of the central protrusion 611 of the U-shaped rod 61 to change in the vertical direction, thereby causing the lifting support plate 5 to move up and down.

[0044] Furthermore, the control mechanism includes a control lever 62 and a toggle key 63. The control lever 62 is fixedly connected to one end of the U-shaped lever 61, and the toggle key 63 is kinetically connected to the control lever 62. The user toggles the toggle key 63 to control the rotation of the U-shaped lever 61 via the control lever 62.

[0045] Furthermore, it also includes a detachable slag collection tray 4 installed in the cooking chamber 11, the slag collection tray 4 having a placement hole 41, the smoking material box 3 being movable up and down within the placement hole 41; the outer periphery of the smoking material box 3 having a flange 31, the flange 31 being located above the slag collection tray 4.

[0046] When the slag tray 4 is removed from the cooking chamber, the flange 31 of the smoking material box 3 abuts against the slag tray 4 to prevent the smoking material box 3 from falling out of the placement hole 41, so that the smoking material box 3 can be removed from the cooking chamber 11 along with the slag tray 4, which facilitates the addition of smoking material and the cleaning of the smoking material box 3.

[0047] Furthermore, it also includes a second heating element 21 and a steam device, the second heating element 21 being disposed above the cooking chamber 11; the steam device includes a water tank 7 and a water supply mechanism 8, the water supply mechanism 8 being used to supply water to the water tank 7, the water tank 7 being disposed above the second heating element 21.

[0048] The downward heat radiation from the second heating element 21 and the upward heat radiation from the first heating element 2 can simultaneously heat the food, improving the baking efficiency. The upward heat radiation from the second heating element 21 can also heat the water in the water tank 7 above to generate steam, effectively utilizing the heat from the second heating element 21. By setting up the water tank 7 and the water supply mechanism 8, steam can be added to the food during the smoking and baking process, preventing the food surface from dehydrating too quickly and forming a membrane during high-temperature smoking. This allows the smoke to penetrate deeper into the food, resulting in better cooking results.

[0049] Furthermore, the water supply mechanism 8 includes a water tank 82, a water pump 83, and a water outlet pipe 84 connected in sequence via a connecting pipe 81; the water supply mechanism 8 also includes a water tank bracket 85, on which the water tank 82 is detachably mounted; the water tank 82 is provided with a one-way valve 821, and the water tank bracket 85 is provided with a hollow push rod (not shown in the figure) connected to the water pump 83, which is used to trigger the one-way valve 821 to open.

[0050] With the above structural design, when the water tank 82 is installed on the water tank bracket 85, the hollow top rod triggers the one-way valve 821 to open, allowing the water in the water tank 82 to flow out sequentially through the one-way valve 821 and the hollow top rod; and when the water tank 82 is removed from the water tank bracket 85, the one-way valve 821 closes, thus facilitating the addition of water to the water tank 82.

[0051] Furthermore, the water tank support 85 is equipped with a water level sensor 851, which is used to sense the water level inside the water tank 82. When the water level sensor 851 senses that the water level inside the water tank 82 is too low, it can notify the user to add water to the water tank 82.

[0052] When using the smoke oven described in this utility model, the required smoking materials are placed in the smoking material box 3, and then the smoking material box 3 is placed in the placement hole 41 of the slag collection tray 4. The slag collection tray 4 is installed in the cooking chamber 11, and the food is placed in the cooking chamber 11. Water is added to the water tank 82, and then the water tank 82 is installed on the water tank bracket 85. The hollow top rod on the water tank bracket 85 triggers the one-way valve 821 of the water tank 82 to open, so that the water tank 82 is connected to the water pump 83 through the connecting pipe 81. The second heating element 21 and the first heating element 2 are controlled to work. The downward heat radiation of the second heating element 21 and the upward heat radiation of the first heating element 2 can heat the food simultaneously. The downward heat radiation from the heating element 2 heats the smoking material, generating smoke to smoke the food. Moving the toggle key 63 via the control lever 62 rotates the U-shaped rod 61, causing the vertical height of the protruding part 611 in the middle of the U-shaped rod 61 to change. This causes the lifting support plate 5 and the smoking material box 3 to move up and down synchronously, allowing the smoking material box 3 to move closer to or further away from the first heating element 2, thus controlling the amount of smoke. The water pump 83 is then activated, pumping water from the water tank 82 into the water trough 7. The upward heat radiation from the second heating element 21 heats the water in the water trough 7, generating steam to supplement the food with steam. Example

[0053] like Figure 7As shown, this utility model provides a smoke oven, whose structure is basically the same as that of Embodiment 1, except that it also includes a third heating element 22 located at the lower part of the cooking chamber 11, and the water tank 7 is positioned differently. In this embodiment, the water tank 7 is located below the third heating element 22.

[0054] The downward heat radiation from the second heating element 21 and the upward heat radiation from the first heating element 2 and the third heating element 22 can simultaneously heat the food, improving the baking efficiency. The downward heat radiation from the third heating element 22 heats the water in the water tank 7 to generate steam, effectively utilizing the heat of the third heating element 22.

[0055] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
