Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a gas stove. Background Art

[0002] At present, the intelligent high-fire juice collection and soup cooking functions in gas stoves generally detect that the water in the pot is boiling, and then adjust the gas stove to a certain firepower and continue cooking for a certain time. This method needs to be improved in terms of user experience, because the specific firepower and time are not suitable for different pots (different materials, different heat conduction speeds) and ingredients of different weights, and the actual juice collection or stewed soup tastes poor.

[0003] In existing gas stoves, because the temperature sensing probe for detecting temperature and the weighing plate for detecting weight both bear the weight of the pot, when detecting temperature and weight at the same time, the temperature sensing probe will affect the accuracy of weighing. As a result, existing gas stoves generally only detect temperature or only detect weight. When performing intelligent cooking (such as collecting juices or making soup over high heat), the cooking effect is difficult to achieve the user's ideal goal due to insufficient information collected.

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0035] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] like Figure 1 As shown, this embodiment provides a gas stove, including a stove housing 10, a burner 40 and a pot rack 50. The stove housing 10 includes a panel 11 and a bottom plate 12 fixed to the bottom of the panel 11. A receiving cavity is formed between the bottom plate 12 and the panel 11. The receiving cavity can be used to place a part of the burner 40, a gas pipeline and other structures. A through hole is provided on the panel 11. At least the top of the burner 40 passes through the through hole and extends out of the table. The pot rack 50 is sleeved on the outside of the burner 40 to support the pot so that the pot is located above the burner 40.

[0038] To facilitate intelligent cooking, the gas stove also includes a weighing mechanism 20 and a temperature measuring mechanism 30. The weighing mechanism 20 is used to obtain the weight of the pot and the food therein, and the temperature measuring mechanism 30 is used to obtain the temperature of the pot and the food therein. By obtaining the weight information and the temperature information, intelligent cooking programs are performed, such as the intelligent high-fire juice collection program, the intelligent soup-making program, etc., to ensure the cooking taste.

[0039] Combination Figure 2 and Figure 3 As shown, the weighing mechanism 20 includes a load-bearing component 21 and a weighing sensor 22. The weighing sensor 22 is arranged on the cooker housing 10. The top of the load-bearing component 21 extends through the through hole on the panel 11 to the top of the panel 11, and is used to bear the pot rack 50. The bottom of the load-bearing component 21 is connected to the force-bearing end of the weighing sensor 22. The weight of the pot and the food therein can be transmitted downward to the weighing sensor 22 through the load-bearing component 21, so that the force-bearing end of the weighing sensor 22 generates an electrical signal due to the force, thereby measuring the weight information of the pot and the food therein through the weighing sensor 22. Among them, the weighing sensor 22 is a cantilever weighing sensor.

[0040] The temperature measuring mechanism 30 includes a temperature detection mounting frame 32 and a temperature sensor 31. The temperature detection mounting frame 32 is arranged in the stove shell 10, and the temperature sensor 31 is arranged on the temperature detection mounting frame 32. The temperature sensing end of the temperature sensor 31 extends from the through hole to the outside of the stove shell 10 so as to abut against the pot, thereby measuring the temperature of the pot and the food therein.

[0041] In order to avoid mutual interference between the temperature measuring mechanism 30 and the weighing mechanism 20 and to ensure the smooth realization of the temperature measuring function and the weighing function, in this embodiment, the temperature detection mounting frame 32 is movably connected with the load-bearing component 21 so that the temperature detection mounting frame 32 can have a certain movable space relative to the load-bearing component 21 in the vertical direction. At the same time, it is ensured that the force applied to the temperature sensor 31 when it abuts against the cookware can be transmitted to the load-bearing component 21 through the temperature detection mounting frame 32.

[0042] When the cookware is placed on the cooker rack 50, the temperature sensor 31 and the load-bearing assembly 21 both bear the weight of the cookware and the food therein, that is, the temperature measuring mechanism 30 shares part of the weight of the cookware and the food therein, resulting in inaccurate measurement results of the weighing mechanism 20, affecting the smart cooking effect. This is why existing gas stoves only have a temperature measuring function or only have a weighing function.

[0043] In order to prevent the temperature measuring mechanism 30 from affecting the detection accuracy of the weighing mechanism 20, the temperature detection mounting frame 32 is connected to the load-bearing component 21, so that the force borne by the temperature sensor 31 when it abuts against the pot can be transmitted to the load-bearing component 21 through the temperature detection mounting frame 32, and then transmitted to the weighing sensor 22 through the load-bearing component 21, so that the weighing mechanism 20 can accurately obtain the weight information. In other words, part of the weight of the pot and the food therein is directly transmitted to the weighing sensor 22 through the load-bearing component 21, and the other part is transmitted to the weighing sensor 22 by passing through the temperature sensor 31, the temperature detection mounting frame 32 and the load-bearing component 21 in sequence, so as to ensure the accuracy of the weighing result.

[0044] Since the bottom shapes of different cookware are different, for example, the bottom surfaces of some cookware are flat, and the bottom surfaces of some cookware are curved, in order to ensure that the temperature sensing end of the temperature sensor 31 can contact with different cookware, ensure that the cookware is placed stably, and avoid the temperature sensing end of the temperature sensor 31 being damaged by excessive force, the temperature sensor 31 needs to have a certain degree of freedom in the vertical direction.

[0045] To this end, the temperature detection mounting frame 32 is movably connected to the load-bearing component 21 so that the temperature detection mounting frame 32 can move in the vertical direction relative to the load-bearing component 21. After the cookware is placed on the cooker rack 50, the cookware contacts the temperature sensor 31. Under the action of the force applied by the cookware, the temperature measuring mechanism 30 adaptively moves downward in the vertical direction relative to the load-bearing component 21 to ensure that the temperature sensor 31 is in contact with the cookware, thereby avoiding damage to the temperature sensor 31.

[0046] In addition, the temperature detection mounting frame 32 can move relative to the load-bearing component 21 in the vertical direction, and can also avoid the generation of pulling force between the load-bearing component 21 and the temperature detection mounting frame 32, thereby ensuring that the measurement of the weighing sensor 22 is more accurate.

[0047] like Figure 3 As shown, the load-bearing component 21 includes a weighing pan 211 and a load-bearing column 212. The weighing pan 211 is arranged above the cooker housing 10 at intervals. The weighing pan 211 is used to support the pot rack 50. When the pot is placed on the pot rack 50, the weighing pan 211 can move downward relative to the panel 11. A gap is provided between the weighing pan 211 and the panel 11, and the gap can provide a movement space for the weighing pan 211 to avoid the weighing pan 211 contacting the panel 11 and failing to weigh accurately. The top end of the load-bearing column 212 is connected to the weighing pan 211, and the bottom end is connected to the force-bearing end of the weighing sensor 22. The force exerted on the weighing pan 211 is transmitted downward to the weighing sensor 22 through the load-bearing column 212 to detect weight information.

[0048] To ensure the accuracy of the weighing result, the load-bearing column 212 extends vertically so that the extension direction of the load-bearing column 212 is the same as the gravity direction of the cookware and the food therein, thereby improving the accuracy of force transmission.

[0049] like Figure 4 As shown, the temperature detection mounting frame 32 is elastically connected to the load-bearing component 21 through an elastic member 34, so that the temperature detection mounting frame 32 can adaptively float up and down according to the stress condition of the temperature sensor 31, which can not only avoid damage to the temperature sensor 31, but also achieve automatic reset, so that the temperature sensor 31 can protrude from the weighing plate 211 and the burner 40, and provide pre-pressure for the contact between the temperature sensor 31 and the cookware, so as to ensure that the temperature sensor 31 can always maintain contact with the cookware on the pot rack 50, thereby improving the accuracy of temperature detection.

[0050] Specifically, one end of the elastic member 34 is connected to the load-bearing assembly 21, and the other end is connected to the temperature detection mounting frame 32. The elastic member 34 is used to drive the temperature detection mounting frame 32 to move upward. The direction of the elastic force of the elastic member 34 on the temperature detection mounting frame 32 is upward, so that the temperature detection mounting frame 32 has a tendency to drive the temperature sensor 31 to move upward and contact the pot, ensuring that the temperature sensor 31 can always contact the pot on the pot rack 50. The pressure of the pot on the temperature sensor 31 is converted into the elastic force of the elastic member 34, and is applied to the load-bearing assembly 21 through the elastic member 34 to be transmitted to the weighing sensor 22.

[0051] In order to provide guidance for the up and down floating of the temperature measuring mechanism 30 and prevent the temperature sensor 31 from being unable to contact the cookware due to position offset, the temperature detection mounting frame 32 can be slidably mounted on the load-bearing component 21 to provide guidance for the movement of the temperature detection mounting frame 32 through the sliding cooperation between the two.

[0052] In this embodiment, the temperature detection mounting frame 32 is mounted outside the load-bearing column 212. The load-bearing column 212 not only plays a role in transmitting force downward, but also plays a guiding role for the temperature detection mounting frame 32, thereby preventing the temperature sensor 31 from being damaged or having measurement errors due to the movement direction of the temperature detection mounting frame 32 deviating from the vertical direction.

[0053] Optionally, the elastic member 34 is sleeved outside the load-bearing column 212 so that the elastic member 34 can be guided by the load-bearing column 212 to prevent the direction of the elastic force applied by the elastic member 34 to the temperature detection mounting frame 32 from being offset.

[0054] In this embodiment, the elastic member 34 is a spring, which has a simple structure and low cost, and is helpful to reduce the cost of the gas stove.

[0055] Among them, the spring can be a tension spring, the top end of the tension spring is connected to the load-bearing column 212, and the bottom end of the tension spring is connected to the temperature detection mounting frame 32. The tension spring is always in a stretched state, and the direction of the elastic force applied by the tension spring to the temperature detection mounting frame 32 is vertically upward.

[0056] In some embodiments, the spring can be a compression spring, the top end of which is connected to the temperature detection mounting frame 32, and the bottom end of which is connected to the load-bearing column 212. The compression spring is always in a compressed state, and the direction of the elastic force applied by the compression spring to the temperature detection mounting frame 32 is vertically upward.

[0057] In other embodiments, the elastic member 34 may also be other structures, such as an elastic block made of elastic material.

[0058] In order to facilitate fixing the initial position of the temperature measuring mechanism 30, the load-bearing column 212 includes a load-bearing section 21211 and a guide section 21212. Both ends of the guide section 21212 are connected to the load-bearing section 21211. The outer diameter of the guide section 21212 is smaller than the outer diameter of the load-bearing section 21211, so that a limiting groove is formed on the load-bearing column 212 outside the guide section 21212. The temperature probe mounting frame 32 is slidably mounted on the guide section 21212, and the temperature probe mounting frame 32 slides in the limiting groove. The connection position of the temperature probe mounting frame 32 and the load-bearing column 212 can be limited by the limiting groove.

[0059] Specifically, a guide hole that cooperates with the guide section 21212 is provided on the temperature detection mounting frame 32, and the diameter of the guide hole is larger than the outer diameter of the guide section 21212 and smaller than the outer diameter of the load-bearing section 21211. This arrangement can limit the sliding range of the temperature detection mounting frame 32 relative to the load-bearing column 212 within the limiting groove, thereby preventing the temperature detection mounting frame 32 from being separated from the guide section 21212.

[0060] To facilitate the cooperation between the temperature detection mounting frame 32 and the load-bearing column 212, the load-bearing column 212 can be set as a splicing structure, for example, the guide section 21212 and one of the load-bearing sections 21211 can be detachably connected to facilitate the cooperation between the guide hole and the guide section 21212.

[0061] In order to facilitate the connection between the elastic member 34 and the load-bearing column 212 , the elastic member 34 is also connected to a clamping spring 33 , and the clamping spring 33 is clamped and fixed on the load-bearing column 212 to facilitate the connection between the elastic member 34 and the load-bearing column 212 .

[0062] In this embodiment, the temperature detection mounting frame 32 includes a temperature detection bracket 321 and a temperature detection fixing plate 322. The temperature detection bracket 321 is vertically arranged in the accommodating cavity. The top end of the temperature detection bracket 321 is connected to the temperature sensor 31. The bottom end of the temperature detection bracket 321 is fixedly connected to the temperature detection fixing plate 322. A guide hole is provided on the temperature detection fixing plate 322 to cooperate with the guide section 21212 on the load-bearing column 212.

[0063] Optionally, the temperature detection bracket 321 and the temperature detection fixing plate 322 may be fixedly connected by screws.

[0064] In order to improve the weighing accuracy, a plurality of load-bearing columns 212 are provided, and the plurality of load-bearing columns 212 are evenly spaced along the circumference of the weighing plate 211, and each load-bearing column 212 is correspondingly provided with a weighing sensor 22. By providing a plurality of load-bearing columns 212, the supporting effect of the weighing plate 211 can be improved, and the weighing plate 211 can be made more stable, and the pressure of the pot rack 50 and the pot on the weighing plate 211 is more uniform; each load-bearing column 212 is connected to a weighing sensor 22, and the plurality of weighing sensors 22 are spaced around the circumference of the weighing plate 211, so that when the pot is offset, each weighing sensor 22 can be evenly stressed, thereby improving the measurement accuracy of each weighing sensor 22 and avoiding the generation of eccentric load.

[0065] To further improve the accuracy of the temperature and weight detection results, the vertical center line of the temperature sensor 31 and the vertical center line of the load-bearing assembly 21 are coincident with the axis of the pot rack 50, so that the force direction of the temperature sensor 31 and the load-bearing assembly 21 coincides with the force direction of the pot rack 50, and the detection result is more accurate. Among them, the weighing plate 211 is an annular plate with a central hole, and the temperature sensor 31 passes through the central hole to extend above the weighing plate 211 and the burner 40 to contact the pot.

[0066] It should be noted here that the vertical center line of the load-bearing component 21 is the axis of the weighing pan 211 .

[0067] In this embodiment, when the weight of the food or water in the cookware changes, the distance between the weighing plate 211 and the panel 11 also changes, thereby changing the pressure applied by the load-bearing component 21 to the weighing sensor 22. The changes in the food and water in the cookware can then be reflected by the detection value of the weighing sensor 22 to assist in intelligent cooking.

[0068] Optionally, the maximum spacing between the weighing pan 211 and the top surface of the cooker housing 10 is 3 mm-5 mm, for example, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm, 4.9 mm or 5 mm. In other embodiments, the maximum spacing between the weighing pan 211 and the panel 11 can be adjusted according to actual needs.

[0069] In this embodiment, the weighing sensor 22 is arranged on the outer bottom surface of the stove shell 10, that is, the weighing sensor 22 is arranged on the outer bottom surface of the chassis 12, part of the load-bearing column 212 is located in the accommodating cavity, and the weighing pan 211 is located above the stove shell 10. The heat generated by the burner 40 when working needs to pass through the weighing pan 211, the panel 11, the load-bearing column 212 and the chassis 12 in sequence before it can reach the weighing sensor 22, so that the weighing pan 211, the panel 11, the load-bearing column 212 and the chassis 12 can effectively insulate the weighing sensor 22, thereby reducing the influence of the conductive heat and the radiant heat on the weighing sensor 22 when the gas stove is working.

[0070] Specifically, the weighing mechanism 20 further includes a weighing mounting plate 23 , the weighing mounting plate 23 is fixedly connected to the chassis 12 , and the weighing sensor 22 is disposed on the weighing mounting plate 23 .

[0071] In order to facilitate the connection between the load-bearing column 212 and the weighing sensor 22, the load-bearing column 212 includes a column 2121 and a weighing foot 2122. One end of the column 2121 is connected to the weighing pan 211, and the other end passes through the chassis 12 and is connected to the weighing foot 2122. The weighing foot 2122 is connected to the force-bearing end of the weighing sensor 22.

[0072] Optionally, the gas stove also includes a control component arranged on the stove shell 10, which is electrically connected to the weighing sensor 22 and the temperature sensor 31 respectively, and is used to receive detected weight information and temperature information, so as to control the flame size and start and stop time of the burner 40 according to the weight information and temperature information, thereby realizing intelligent cooking.

[0073] When the temperature detected by the temperature sensor 31 reaches the preset temperature, the temperature sensor 31 sends the detection result to the control component, and the control component collects the monitoring data of the weight of the food in the cooker by the weighing sensor 22. When the weight change of the food reaches the preset value, the gas source is cut off, the burner 40 stops working, and cooking ends; when the weight change of the food is less than the preset value, the gas stove continues to work until the weight change of the food reaches the preset value, the gas source is cut off, and cooking ends; when the weight change of the food is greater than the preset value, the gas stove cuts off the gas source and cooking ends.

[0074] Optionally, the control component includes a display panel 60, which is disposed on the panel 11 and is used to display cooking information, such as temperature and weighing results.

[0075] It should be noted here that the weighing sensor 22 and the temperature sensor 31 are common sensors in this field. The connection relationship, specific structure and specific control method between the weighing sensor 22, the temperature sensor 31 and the control component and other components are all relatively conventional means in this field. This embodiment can adopt any connection relationship, specific structure and specific control method of the weighing sensor 22, the temperature sensor 31 and other components in the prior art. The utility model will no longer describe in detail the connection relationship, specific structure and specific control method between the weighing sensor 22, the temperature sensor 31 and other components.

[0076] With the gas stove provided in this embodiment, when the cookware is placed on the cooker rack 50, the temperature sensor 31 and the cooker rack 50 move downward due to the shape of the cookware and gravity, and the cooker rack 50 transfers the weight of the cookware to the weighing plate 211, and the weighing plate 211 transfers the gravity received to the weighing sensor 22 via the load-bearing column 212; and the temperature sensor 31 moves downward to compress the elastic member 34, and the spring deformation force generated by the compression of the elastic member 34 is transferred to the weighing sensor 22 via the load-bearing column 212, that is, the gravity is finally collected to the load-bearing column 212 and transmitted to the weighing sensor 22, so that the gas stove can weigh the cookware and food, and detect the temperature of the cookware and food during operation.

[0077] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
