Description

Technical Field

[0001] The utility model relates to the technical field of cooking appliances, in particular to an air path component, a panel assembly and an oven. Background Art

[0002] Gas grills are often a must-have for barbecues at gatherings because of their smokeless, environmentally friendly, and unrestricted usage scenarios.

[0003] In the prior art, gas ovens generally use mechanical methods to manually adjust the firepower. However, during manual adjustment, the cook needs to rely on experience to adjust the firepower. If the cook is inexperienced, the food may be burnt or even carbonized.

[0004] In order to avoid relying on the experience of the cooking staff, the gas oven can be controlled by the controller's automatic temperature control method. After adopting the controller's automatic temperature control method, it is necessary to abandon the mechanical valve and introduce a proportional valve into the gas path structure of the gas oven. The controller controls the opening of the proportional valve to control the gas volume, and finally realizes automatic control of the firepower and temperature.

[0005] In the prior art, when a gas circuit assembly adopts a mechanical valve, the mechanical valve is fixedly installed on the furnace body of the gas grill, and the nozzle is directly screwed to the gas outlet end of the mechanical valve; the head of the burner of the gas grill passes through the nozzle. Due to processing and assembly errors, the head of the burner and the nozzle are often not coaxial during assembly, resulting in the burner head overlapping the gas outlet end of the mechanical valve after assembly.

[0006] When the mechanical valve is replaced with a proportional valve, the original gas circuit structure of the gas oven cannot be used. Generally, it is necessary to connect a copper or aluminum gas pipe to the output end of the proportional valve, and install the nozzle at the end of the gas pipe away from the proportional valve. In this way, when the gas circuit assembly with the proportional valve is installed on the furnace body, if the head of the burner overlaps the nozzle, the gas pipe will be deformed due to the soft material of the gas pipe during transportation due to the overlap force of the burner head, affecting the centering of the nozzle and the burner, causing the burner to have flame separation, yellow flame, or even fail to ignite when in use.

[0007] Therefore, there is an urgent need for an air path component, a panel assembly and an oven to solve the above problems. Utility Model Content

[0008] One of the technical problems solved by the utility model is to provide a gas path component, which can effectively solve the technical problem in the prior art that the original gas path structure of the gas oven cannot be used after a proportional valve is introduced into the gas path structure of the gas oven.

[0083] The nozzle module 5 includes a nozzle base 51, a nozzle 52, and a nozzle base bracket 53. The nozzle base bracket 53 is configured to be fixedly connected to the furnace body 100 of the grill. The nozzle base 51 is fixedly installed on the nozzle base bracket 53. The outlet of the second gas pipeline 4 is connected to the intake end 511 of the nozzle base 51, and the nozzle 52 is provided at the outlet end 512 of the nozzle base 51.

[0084] The air path assembly provided in this embodiment integrates a proportional valve 3, facilitating the control of the opening degree of the proportional valve 3 by a controller, controlling the air output of the proportional valve 3, thereby being able to control the air output of the nozzle 52. The nozzle 52 is used to communicate with the burner assembly of the grill and supply gas to the burner assembly, ultimately achieving the control of the firepower size, that is, achieving the control of the temperature size of the grill.

[0085] Moreover, in this air path assembly, since a second gas pipeline 4 is provided at the outlet of the proportional valve 3 and the outlet of the second gas pipeline 4 is connected to the intake end 511 of the nozzle base 51, the nozzle base bracket 53 can achieve the fixed installation of the nozzle module 5 on the furnace body 100.

And the nozzle 52 is fixedly installed on the furnace body 100 through the nozzle base bracket 53, which can ensure the accuracy of the position of the nozzle 52, and further ensure the centering of the nozzle 52 and the burner assembly during assembly.

[0086] Furthermore, in one of the embodiments, refer to Figure 3 , the nozzle base bracket 53 is generally in a "C" shape, including a nozzle base mounting plate 531 and two nozzle base bracket mounting plates 532.

[0087] Among them, the nozzle base 51 is fixedly installed on the nozzle base mounting plate 531, and the outlet end 512 of the nozzle base 51 passes through the nozzle base mounting plate 531.

[0088] The two nozzle holder bracket mounting plates 532 are respectively located on both sides of the nozzle holder mounting plate 531 . The nozzle holder bracket mounting plates 532 are configured to be fixedly connected to the furnace body 100 . The nozzle 52 is located between the two nozzle holder bracket mounting plates 532 .

[0091] Furthermore, the nozzle seat 51 is fixedly mounted on the nozzle seat mounting plate 531 by means of a bolt and nut assembly, and both the nozzle seat 51 and the nozzle seat mounting plate 531 are provided with mounting holes that cooperate with the bolts.

[0092] Furthermore, in order to fix the nozzle seat bracket mounting plate 532 on the furnace body 100, a connecting flange is provided at one end of each nozzle seat bracket mounting plate 532 away from the nozzle seat mounting plate 531, and the threaded connection part passes through the connecting flange and is then fastened to the furnace body 100 to achieve fixed installation of the nozzle seat bracket 53.

[0093] See also Figure 1 and Figure 2 In order to ensure the position stability of the main gas valve 1, the gas circuit assembly also includes a main gas valve bracket 6, the main gas valve 1 is fixedly mounted on the main gas valve bracket 6 through a threaded connector, and the main gas valve bracket 6 is fixedly mounted on the furnace body 100.

[0094] Furthermore, the inlet of the main gas valve 1 is connected to an air inlet connector 7, which is connected to an air source to supply air to the gas circuit assembly. The outlet of the main gas valve 1 is connected to the inlet of the first gas pipeline 2 through a main valve outlet connector 11.

[0095] Furthermore, in order to ensure the position stability of the proportional valve 3 , the gas circuit assembly further includes a proportional valve bracket 8 , which can be fixedly mounted on the furnace body 100 , and the proportional valve 3 is fixedly mounted on the proportional valve bracket 8 via a threaded connector.

[0096] Specifically, a proportional valve bracket flange is provided at both ends of the proportional valve bracket 8 , and the proportional valve bracket flange is fixedly mounted on the furnace body 100 through a threaded connector.

[0097] Specifically, the outlet of the first gas supply pipe 2 is connected to the proportional valve 3 through the proportional valve air inlet connector 31 .

[0098] Optionally, in this embodiment, the proportional valve 3 includes three independent outlets, each outlet of the proportional valve 3 is correspondingly provided with a second gas pipe 4, and each second gas pipe 4 is correspondingly provided with a nozzle module 5. In this way, the gas circuit assembly can supply gas to three burner assemblies at the same time. Specifically, the lengths of the three second gas pipes 4 are different.

[0099] Of course, in other embodiments, the number of outlets of the proportional valve 3 may also be other numbers, such as one, two, four or more, which can be set as needed and is not restricted too much here.

[0102] Embodiment 2

[0103] See also Figure 4-Figure 7 The present embodiment provides a panel assembly, which is applied to a gas grill to facilitate cooks to control the gas grill.

[0104] Specifically, the panel assembly includes a front panel 10, a rear cover plate 20, a control screen assembly 40 and the air path assembly in the first embodiment.

[0106] Preferably, the rear cover plate 20 is closer to the combustion chamber of the oven, so the material of the rear cover plate 20 is a heat-insulating material.

[0108] The gas circuit assembly is located in the installation cavity 30 , the nozzle seat bracket 53 is fixedly installed on the rear cover plate 20 , and the control screen assembly 40 is electrically connected to the proportional valve 3 .

[0109] The nozzle holder bracket 53 is fixedly mounted on the rear cover plate 20 , thereby achieving a fixed connection between the nozzle holder bracket 53 and the furnace body 100 .

[0110] The panel assembly provided in this embodiment, the control screen assembly 40 is electrically connected to the proportional valve 3, so that the cooking personnel can set a preset temperature by operating the control screen assembly 40. When the actual temperature of the oven is lower than the preset temperature, the controller will control the gas outlet of the proportional valve 3 to increase; when the actual temperature of the oven is higher than the preset temperature, the controller will control the gas outlet of the proportional valve 3 to decrease.

[0111] In the panel assembly, since the second gas pipe 4 is arranged at the outlet of the proportional valve 3 and the outlet of the second gas pipe 4 is connected to the air inlet end 511 of the nozzle seat 51, the nozzle seat bracket 53 can realize the fixed installation of the nozzle module 5 on the furnace body 100. In this way, the outlet of the second gas pipe 4 is fixed by the nozzle seat bracket 53 to avoid deformation of the second gas pipe 4 during transportation, and the nozzle 52 is fixedly installed on the furnace body 100 by the nozzle seat bracket 53, which can ensure the centering of the nozzle 52 and the burner assembly when they are assembled.

[0113] Specifically, the nozzle seat mounting plate 531, the two nozzle seat bracket mounting plates 532 and the rear cover plate 20 are jointly enclosed to form a protective space 302 to protect the nozzle 52 and prevent the nozzle 52 from being displaced or deflected due to collision with other components during transportation, thereby affecting the subsequent installation of the nozzle 52 and the burner assembly 200.

[0114] See also Figure 5 and Fig. 9 In one embodiment, a burner air avoidance hole 201 is opened on the rear cover plate 20, and the nozzle 52 is coaxially arranged with the burner air avoidance hole 201.

[0118] The setting of the screen avoidance hole 101 allows the control screen assembly 40 to be exposed, making it convenient for the cook to operate the control screen assembly 40 .

[0119] The pressing ring 102 abuts against the control panel assembly 40 , so that the control panel assembly 40 is stably installed, and the control panel assembly 40 will not move or shake due to the pressing force of the cook to operate the control panel assembly 40 .

[0120] Further, see Figure 8 In one embodiment, a sealing area 301 is formed between the pressing ring 102 and the control screen assembly 40 , and the sealing area 301 is filled with sealing material.

[0121] The sealing area 301 is filled with sealing material, which can prevent impurities such as water or dust from entering the installation cavity 30 through the gap between the pressing ring 102 and the control screen assembly 40 .

[0125] The control panel cover plate 403 is located on a side of the control panel 402 facing away from the fixing plate 401 and is fixedly connected to the fixing plate 401 .

[0126] Specifically, in this embodiment, the control screen 402 has a display function and a touch control function. For example, the control screen 402 can display a preset temperature, and the cook can adjust the preset temperature by touching the control screen 402.

[0127] More specifically, the control screen 402 includes a control screen body 4022 and a touch panel 4021 , and the touch panel 4021 is disposed on the front surface of the control screen body 4022 .

[0130] Specifically, the positioning flange 4012 located at the lowermost side can receive the control screen 402 , and the four positioning flanges 4012 along the four sides of the screen mounting hole 4011 together restrict the control screen 402 .

[0144] Embodiment 3

[0145] See also Figure 11-Figure 14 , this embodiment provides an oven.

[0146] Specifically, the oven is a gas oven.

[0147] See also Figure 11-13 The oven includes an oven body 100 and a panel assembly of the second embodiment.

[0148] The panel assembly is assembled in the front area of ​​the furnace body 100 .

[0149] The oven provided in this embodiment includes the above-mentioned panel assembly. In the panel assembly, the control panel assembly 40 is electrically connected to the proportional valve 3 of the gas circuit assembly, so that the cook can set a preset temperature by controlling the control panel assembly 40. When the actual temperature of the oven is lower than the preset temperature, the controller will control the gas output of the proportional valve 3 to increase; when the actual temperature of the oven is higher than the preset temperature, the controller will control the gas output of the proportional valve 3 to decrease. In this way, the automatic temperature control of the oven is realized.

[0150] In the panel assembly of the oven, since the second gas pipe 4 is arranged at the outlet of the proportional valve 3 and the outlet of the second gas pipe 4 is connected to the air inlet end 511 of the nozzle seat 51, the nozzle seat bracket 53 can realize the fixed installation of the nozzle module 5 on the furnace body 100. In this way, the outlet of the second gas pipe 4 is fixed by the nozzle seat bracket 53 to avoid deformation of the second gas pipe 4 during transportation, and the nozzle 52 is fixedly installed on the furnace body 100 by the nozzle seat bracket 53, which can ensure the centering of the nozzle 52 and the burner assembly when they are assembled.

[0151] Specifically, the burner assembly 200 is assembled in the central area of ​​the furnace body 100, including a burner body 2001, on which a thermocouple 2002 and an ignition needle 2003 are arranged, a nozzle avoidance hole 2005 is arranged at one end of the burner body 2001, and a burner body fixing hole 2004 is arranged at the other end.

[0152] The oven is provided with a burner fixing bracket 300 for mounting the burner assembly 200 .

[0153] When the burner assembly 200 is installed on the oven, the nozzle avoidance hole 2005 is aligned with the nozzle 52 and the nozzle 52 is inserted into the nozzle avoidance hole 2005 , and the other end of the burner body 2001 is installed on the burner fixing bracket 300 through the burner body fixing hole 2004 .

[0154] Furthermore, in this embodiment, a temperature detection member 400 is also provided on the oven body 100 to detect the temperature of the oven.

[0155] Specifically, a left stage assembly 1001 is disposed on the left side of the furnace body 100 , and a right stage assembly 1002 is disposed on the right side. An upper cover assembly 1003 is also disposed on the furnace body 100 , and the temperature detection component 400 is disposed on the upper cover assembly 1003 .

[0156] Optionally, the temperature detection component 400 is a temperature measuring probe.

[0157] The oven further comprises a frame assembly 500, and the oven body 100 is arranged on the frame assembly 500, so as to facilitate the movement of the oven.

[0158] On the furnace body 100 , a fire baffle is arranged above the burner assembly 200 , a grill 1004 is arranged above the fire baffle, and a heat preservation rack 1005 is also arranged above the grill 1004 . When the upper cover assembly 1003 is in an open state, the temperature detection component 400 is located above the heat preservation rack 1005 .

[0159] Exemplarily, in this embodiment, the working process of the oven is as follows:

[0160] After receiving the working instruction, the controller controls the main gas valve 1 and the proportional valve 3 to open, and at the same time the ignition needle 2003 starts to discharge, and the gas enters the burner body 2001 and then sprays out from the fire hole of the burner body 2001. Under the action of the ignition needle 2003, the gas sprayed from the fire hole is ignited;

[0161] The burning flame heats the thermocouple 2002, and the temperature of the thermocouple 2002 is transmitted to the controller in real time to indicate that the ignition is successful;

[0162] During the flame combustion process, the internal air of the furnace body 100 is heated and rises, the temperature detection component 400 detects the temperature of the rising airflow, and transmits the temperature of the rising airflow to the controller in real time. The controller compares the detection value of the temperature detection component 400 with the preset temperature, and adjusts the gas output of the proportional valve 3 according to the difference between the two, thereby realizing automatic adjustment of the flame size.
