Description

Technical Field

[0001] The utility model belongs to the technical field of gas stove accessories, and particularly relates to a backless synchronous switch-fire cock valve. Background Art

[0002] A gas stove usually controls the opening and closing of the gas stove through a cock valve. Currently, the more commonly used one is an embedded gas stove. Embedded means that the kitchen countertop is made into a "concave" shape, which can just embed the gas stove, and the stove cabinet of the gas stove is flush with the kitchen countertop. Since the embedded gas stove is beautiful, space-saving and easy to clean, it makes the kitchen look more harmonious and complete, and is more convenient for the supporting design with other kitchen utensils. Therefore, it is favored by the majority of consumers.

[0003] Currently, the solenoid valve adopted needs to press down the valve rod, the valve rod drives the valve needle to push the lever, the lever opens the solenoid valve, and then the intake passage is opened by rotating the angle of the valve rod. This results in a large number of mechanical parts required for the entire valve body, and the valve body needs to be provided with a back cover to form a cavity for accommodating the lever, which further leads to the excessive thickness of the cock valve, so that the thickness of the household gas stove cannot be reduced, thus reducing the user experience during use. Content of the Utility Model

[0004] The utility model aims at the above problems existing in the prior art, and provides a backless synchronous switch-fire cock valve.

Detailed implementation manners

[0040] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical methods of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0041] Embodiment 1

[0042] As Figures 1-6 shown, the present utility model provides a back-coverless synchronous switch gas cock valve, including:

[0043] A valve body 100 having a first air inlet channel 110, a solenoid valve channel 120, a second air inlet channel 130, a main fire outlet channel 140, a secondary fire outlet channel 150, and a valve core cavity 170;

[0044] A self-priming solenoid valve 121 disposed in the solenoid valve channel 120, and the self-priming solenoid valve 121 opens or cuts off the connection between the first air inlet channel 110 and the second air inlet channel 130 by energizing or de-energizing;

[0045] A valve core 160 is rotatably arranged in a valve core cavity 170. By rotating the valve core 160, the communication between the second air inlet passage 130 and the main flame outlet passage 140 and the secondary flame outlet passage 150 can be opened or cut off.

[0046] Two air dampers 180 are provided and are respectively integrated at the flame outlets of the main flame outlet passage 140 and the secondary flame outlet passage 150.

[0047] It should be noted that the solenoid valve in this embodiment is a self - sucking solenoid valve 121. Only by energizing and de - energizing can the purpose of opening or cutting off the communication between the first air inlet passage 110 and the second air inlet passage 130 be achieved, without additional mechanical components such as valve needles and levers in the prior art to open the solenoid valve. Thus, materials are saved and costs are reduced.

[0048] Just because of this, the valve body 100 does not need to additionally install a rear cover on its back to accommodate additional mechanical components. Thus, the thickness of the entire cock is reduced, the thickness of the gas stove is reduced, and the possibility of air leakage is also reduced.

[0049] This design not only reduces the modification of the cabinet structure during installation, reduces the installation cost and time, but also avoids problems such as cabinet waterproofing and insect prevention that may be brought by opening holes, which is beneficial to maintaining the integrity of the cabinet and extending its service life.

[0050] In addition, for the structure where the air damper 180 is installed on the burner, an aluminum pipe, the air damper 180, and a nozzle need to be installed separately, and the installation process is more cumbersome. In contrast, for the cock provided in this embodiment, the air damper 180 is integrated on the valve body 100, can be directly docked with the burner head, does not require additional accessories, and the installation is simpler and more convenient, and costs are saved.

[0051] Preferably, a main fire nozzle 141 is installed in the main flame outlet passage 140, and the air damper 180 is installed on the main fire nozzle 141 through an air damper spring 181. A secondary fire nozzle 151 is installed in the secondary flame outlet passage 150, and the air damper 180 is installed on the secondary fire nozzle 151 through an air damper spring 181. Thus, the purpose of integrating the air damper 180 on the valve body 100 is achieved, and installing it on the burner head can make the air damper 180 closely fit with the burner head.

[0052] Preferably, the first air inlet passage 110 is opened at the bottom of the valve body 100. Compared with the first air inlet passage 110 being opened at the side of the valve body 100, the position design of the first air inlet passage 110 in this embodiment has no height limit and is more versatile.

[0053] Preferably, the solenoid valve passage 120 is located at the side of the valve body 100 and has a solenoid valve passage air outlet hole 122, wherein,

[0054] When the self - priming solenoid valve 121 is not powered on, its piston closes the air outlet hole 122 of the solenoid valve passage. At this time, the first intake passage 110 and the second intake passage 130 are not connected.

[0055] When the self - priming solenoid valve 121 is powered on, its piston moves upward and opens the air outlet hole 122 of the solenoid valve passage. At this time, the first intake passage 110 is connected to the second intake passage 130, and the gas enters the valve body 100.

[0056] Preferably, the main flame outlet passage 140 and the secondary flame outlet passage 150 are arranged in parallel and are respectively connected to the valve core cavity 170. As the valve core 160 rotates, the main flame outlet passage 140, the secondary flame outlet passage 150 are connected to or closed off from the second intake passage 130, thereby achieving the purpose of synchronously firing and extinguishing the flame.

[0057] Among them, the valve core 160 in this embodiment is provided with a valve core communication passage 161, a valve core main - fire air outlet hole 163, a valve core secondary - fire air outlet hole 162, and a valve core fire - keeping hole 164. The valve core communication passage 161 is composed of a valve core intake hole 1611 and an extension section 1612 extending along the surface of the valve core 160. The valve core fire - keeping hole 164 is arranged in a staggered manner with the valve core communication passage 161. Specifically:

[0058] 1. When the valve core 160 is at the 0° position, a sealing angle is formed between the second intake passage 130 and the intake hole or the intake - and - exhaust passage of the valve core 160, and the two are not connected. At this time, the gas cannot enter the main flame outlet passage 140 and the secondary flame outlet passage 150, and the cooking appliance is in the flame - off state.

[0059] 2. When the valve core 160 rotates between 0° and 90°, the valve body 100 is in the initial opening state. The self - priming solenoid valve 121 is opened, and the second intake passage 130 is connected to the first intake passage 110. At this time, the gas sequentially passes through the first intake passage 110, the air outlet hole 122 of the solenoid valve passage and enters the second intake passage 130. Among them,

[0060] When the valve core communication passage 161 is not connected to the second intake passage 130, the valve core main - fire air outlet hole 163 and the valve core secondary - fire air outlet hole 162 are respectively pre - connected to the main flame outlet passage 140 and the secondary flame outlet passage 150. Thus, once the valve core communication passage 161 is connected to the second intake passage 130, the main flame outlet passage 140 and the secondary flame outlet passage 150 can achieve the purpose of synchronously discharging the flame.

[0061] 3. When the valve core 160 rotates after 90°, the valve body 100 is in the latter - stage opening state. When the valve core 160 rotates to a preset angle, the valve core main - fire air outlet hole 163 is closed off from the main flame outlet passage 140, and at the same time, the valve core fire - keeping hole 164 remains connected to the secondary flame outlet passage 150 to keep the cooking appliance in the fire - keeping state.

[0062] Preferably, it further includes a valve cover 190 and a valve stem 191. The valve cover 190 is connected to the valve body 100. The valve stem 191 passes through the valve cover 190 and is connected to the valve core 160 in a matching manner. The valve core 160 is driven to rotate by the valve stem 191 to realize the on-off control of the air flow passage.

[0063] Wherein, one end of the valve core 160 for connecting with the valve stem 191 is provided with a spring cavity 200. A spring 201 is installed in the spring cavity 200. The two ends of the spring 201 are respectively abutted against the valve core 160 and the valve stem 191. On the one hand, the spring 201 plays a role in lifting the valve stem 191. After pressing down the valve stem 191, the child lock is opened and the valve stem 191 can rotate. On the other hand, the spring 201 can also keep the valve core 160 in a conical surface fitting and sealing state without air leakage.

[0064] In addition, sealing plugs 210 are installed on both sides of the valve body 100 to ensure the airtightness inside the valve body 100.

[0065] Embodiment 2

[0066] As Figures 7-8 shown, the difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, another structure of the valve core 160 is provided, which has a valve core intake hole 1611 and a valve core primary and secondary integrated outlet hole 1613. The two are on the same straight line, and can also play the functions of synchronously turning on and off the fire and maintaining the fire, while reducing the length of the valve core to save materials.

[0067] Embodiment 3

[0068] As Figure 9 shown, the difference between Embodiment 3 and Embodiment 1 is that in Embodiment 3, another structure of the valve core 160 is provided, the area of its enlarged valve core communication channel 161 combines the functions of intake and outlet, and it also has a valve core fire-maintaining hole 164, which can also play the functions of synchronously turning on and off the fire and maintaining the fire.

[0069] Embodiment 4

[0070] As Figure 10 shown, the difference between Embodiment 4 and Embodiment 1 is that in Embodiment 2, another structure of the valve core 160 is provided, and only a valve core communication channel 161 is opened on its surface. When the valve core 160 rotates after 90°, the valve body 100 is in the latter stage of opening. When the valve core 160 rotates to a preset angle, the valve core communication channel 161 is closed with the main fire outlet channel 140, and at this time, the valve core communication channel 161 remains connected with the secondary fire outlet channel 150 to keep the cooking appliance in the fire-maintaining state.

[0071] That is, in the fourth embodiment compared with the first embodiment, the valve core fire protection holes 164 on the surface of the valve core 160 are cancelled, and by extending or expanding the ventilation area of the valve core communication channel 161, it still has the function of protecting the fire.

If the specific posture changes, the directional indication will also change accordingly.

[0074] In addition, in the present utility model, descriptions such as "first", "second", and "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0075] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0076] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
