Description

Technical Field

[0001] This utility model relates to the field of stove technology, specifically to a stove. Background Technology

[0002] As the usage rate of gas stoves increases, people's requirements for stove safety are also rising. Gas stoves are usually equipped with external temperature sensors that can detect the temperature at the bottom of the pot. When the temperature at the bottom of the pot exceeds a preset temperature, the stove will automatically shut off to protect the flame. At the same time, if the stove accidentally goes out or if a pot is not placed on the stove for an extended period of time, the gas supply can be cut off immediately based on the detection results of the external temperature sensor to prevent accidents.

[0003] However, external temperature sensors have certain limitations in use. For example, because the external temperature sensor needs to be in contact with the bottom of the pot, only flat-bottomed pans can be used for cooking to avoid interference with the external temperature sensor. Also, the external temperature sensor is easily affected by the flame, which can cause the external temperature sensor to fail to accurately detect the temperature of the bottom of the pot, resulting in the stove malfunctioning and shutting off.

[0004] If the temperature sensor is placed in the bottom shell, it can avoid contact with the bottom of the pot. However, because the space inside the bottom shell is relatively narrow, the temperature sensor will generate heat when it is working. A lot of heat can easily accumulate near the temperature sensor, affecting the detection accuracy and service life of the temperature sensor. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a stove is provided, the technical solution of which is as follows.

[0006] The stove of this utility model includes a bottom shell, a panel, a burner head, and a temperature sensing element. The bottom shell encloses an opening to form a mounting cavity. The panel is disposed on the bottom shell and covers the opening. A portion of the burner head is disposed within the mounting cavity. The temperature sensing element is connected to the burner head and located within the mounting cavity. The bottom shell has a cavity bottom wall opposite the panel. The cavity bottom wall has a first region and a second region. The first region is further away from the panel than the second region. The temperature sensing element has a sensing surface. In a direction perpendicular to the panel, the sensing surface and the first region have a first distance Z1, which is 35mm to 80mm.

[0007] This invention relates to a cooktop that uses a temperature sensor to detect the temperature of the burner head and thus the temperature of the pot bottom. The temperature sensor is housed within the mounting cavity and is unaffected by the flame. Even when using a pointed-bottom pot, the temperature sensor will not interfere with the pot, expanding the cooktop's applicability. Furthermore, the aforementioned first distance between the sensing surface and the first area ensures sufficient heat dissipation space for the temperature sensor, preventing heat accumulation and damage. This effectively improves the accuracy and lifespan of the temperature sensor, enhancing the safety and reliability of the cooktop.

[0008] For example, a controller is disposed within the mounting cavity at a location corresponding to the first area, and a first heat dissipation hole is provided on the first area for the controller to dissipate heat. Thus, the first heat dissipation hole can be formed on the first area, allowing the heat generated by the controller to be dissipated through it, preventing heat accumulation from affecting and damaging components such as the controller and temperature sensing element. This effectively improves the detection accuracy of the temperature sensing element and the service life of the temperature sensing element and controller, thereby enhancing the safety and reliability of the stove's use.

[0009] For example, along the length of the bottom shell, there is a first lateral distance X1 between the sensing surface and the first heat dissipation hole, where the first lateral distance X1 is 150mm to 280mm. This first lateral distance range between the sensing surface and the first heat dissipation hole not only ensures that the heat generated by the temperature sensing element during operation can be dissipated through the first heat dissipation hole, but also prevents the heat generated by the stove head from being rapidly lost through the first heat dissipation hole, thus avoiding inaccurate sensing results from the temperature sensing element. This effectively improves the reliability and accuracy of the temperature sensing element.

[0010] For example, in the width direction of the bottom shell, there is a longitudinal distance Y between the sensing surface and the first heat dissipation hole, and the longitudinal distance Y is 30mm to 85mm. This longitudinal distance range between the sensing surface and the first heat dissipation hole not only ensures that the heat generated by the temperature sensing element during operation can be dissipated through the first heat dissipation hole, but also prevents the heat generated by the stove head from being rapidly lost through the first heat dissipation hole, thus avoiding inaccurate sensing results from the temperature sensing element, effectively improving the reliability and accuracy of the temperature sensing element.

[0011] For example, there are multiple first heat dissipation holes, which are spaced apart along the width of the bottom shell. In this way, the multiple first heat dissipation holes can increase the contact area between heat and the external environment, allowing the heat generated by the controller to be more evenly distributed to the surrounding environment, effectively improving the heat dissipation efficiency of the stove, and increasing the stability and service life of the stove.

[0012] For example, the bottom shell has a cavity sidewall located between the cavity bottom wall and the panel. The second region has an inner region and a peripheral region, with the peripheral region closer to the cavity sidewall than the inner region. The projection of the temperature sensing element onto the plane of the cavity bottom wall is located in the inner region, and a second heat dissipation hole is provided on the inner region for heat dissipation of the temperature sensing element. Thus, the heat generated by the temperature sensing element can be promptly discharged from the mounting cavity through the second heat dissipation hole located in the inner region. Furthermore, the temperature sensing element can be located above the inner region, allowing the hot airflow in the mounting cavity to be quickly discharged along a shorter airflow path, avoiding overheating that may occur due to heat concentration in the area near the temperature sensing element, further improving the accuracy and service life of the temperature sensing element.

[0013] For example, in a direction perpendicular to the panel, there is a second distance Z2 between the sensing surface and the internal area, the second distance Z2 being 35mm to 75mm. This second distance range between the sensing surface and the internal area not only ensures that the heat generated by the temperature sensor during operation can be dissipated through the second heat dissipation hole located on the internal area, but also prevents the heat generated by the burner head from rapidly dissipating through the second heat dissipation hole located on the internal area, thus avoiding inaccurate temperature sensing results. This effectively improves the reliability and accuracy of the temperature sensor.

[0014] For example, the second heat dissipation hole is a circular hole, and the projection of the sensing surface onto the plane of the cavity bottom wall is located inside the circular hole. In this way, the sensing surface of the temperature sensing element can be located directly above the second heat dissipation hole, and the heat generated by the temperature sensing element can be dissipated through the second heat dissipation hole in the first instance, thereby ensuring that the temperature sensing element can always be in a stable and suitable working environment temperature, effectively improving the sensing accuracy and service life of the temperature sensing element, and further improving the safety and reliability of the stove.

[0015] For example, the burner head includes an ejector tube and a bracket. The ejector tube is positioned by the bracket, and a thermocouple is mounted on the bracket. A third heat dissipation hole is provided on the outer perimeter for heat dissipation of the thermocouple. Thus, by mounting the ejector tube and thermocouple on the bracket, the overall structural design of the burner head can be optimized, making it more compact and stable. Furthermore, the positioning of the ejector tube and thermocouple by the bracket simplifies the burner head assembly process, reducing assembly steps and time, and facilitating subsequent maintenance and replacement, significantly reducing maintenance costs. Moreover, the heat generated by the thermocouple can be dissipated through the third heat dissipation hole, preventing heat accumulation from affecting and damaging the temperature sensing element and thermocouple, effectively improving the detection accuracy of the temperature sensing element and the service life of the temperature sensing element and thermocouple, thereby enhancing the safety and reliability of the stove.

[0016] For example, the temperature sensor is mounted on the bracket. Thus, by sensing the temperature of the bracket, the temperature of the pot bottom can be detected (i.e., indirectly detecting the pot temperature). This not only ensures that the temperature sensor can sense the pot bottom temperature in real time, but also avoids interference or damage to the temperature sensor caused by the close proximity of the sensor to the burner flame. This effectively improves the accuracy of the temperature sensing results, thereby enhancing the safety and reliability of the stove.

[0017] For example, the sensing surface forms a surface contact with the bracket. Along the length of the bottom shell, there is a second lateral distance X2 between the sensing surface and the third heat dissipation hole, which is 35mm to 75mm. This surface contact significantly increases the contact area between the temperature sensing element and the bracket, thereby reducing contact thermal resistance and allowing heat from the bracket to be quickly and evenly transferred to the temperature sensing element. Furthermore, the aforementioned second lateral distance between the sensing surface and the third heat dissipation hole not only ensures that the heat generated by the temperature sensing element during operation can be dissipated through the third heat dissipation hole, but also prevents the rapid loss of heat transferred to the bracket through the third heat dissipation hole, thus avoiding inaccurate sensing results and effectively improving the reliability and accuracy of the temperature sensing element.

[0018] For example, the temperature sensing element is mounted on the ejector tube. By sensing the temperature of the ejector tube through the temperature sensing element, the temperature of the pot bottom can be detected (i.e., the temperature of the pot can be detected indirectly). This not only ensures that the temperature sensing element can sense the temperature of the pot bottom in real time, but also avoids interference or damage to the temperature sensing element caused by the close distance between the temperature sensing element and the flame of the burner. This effectively improves the accuracy of the temperature sensing element, thereby improving the safety and reliability of the stove.

[0019] For example, the sensing surface forms a surface contact with the ejector tube. Along the length of the bottom shell, there is a third lateral distance X3 between the sensing surface and the third heat dissipation hole, which ranges from 15mm to 105mm. This surface contact significantly increases the contact area between the temperature sensing element and the ejector tube, thereby reducing contact thermal resistance and allowing heat from the ejector tube to be quickly and evenly transferred to the temperature sensing element. Furthermore, the aforementioned third lateral distance between the sensing surface and the third heat dissipation hole not only ensures that the heat generated by the temperature sensing element during operation can be dissipated through the third heat dissipation hole, but also prevents the rapid loss of heat transferred to the ejector tube through the third heat dissipation hole, thus avoiding inaccurate sensing results and effectively improving the reliability and accuracy of the temperature sensing element.

[0020] For example, the ejector tube is connected to a heat transfer element, and the temperature sensing element is disposed on the heat transfer element. Thus, the temperature sensing element can contact the heat transfer element. When the stove is in combustion mode, since the temperature of the heat transfer element is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the heat transfer element (i.e., indirectly detecting the pot temperature). The temperature sensing element is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that even when using a pointed-bottom pot, the temperature sensing element will not interfere with the pot, expanding the stove's applicability and effectively improving its practicality.

[0021] For example, the sensing surface forms a surface contact with the heat transfer element. Along the length of the bottom shell, there is a fourth lateral distance X4 between the sensing surface and the third heat dissipation hole, ranging from 15mm to 105mm. This surface contact significantly increases the contact area between the temperature sensing element and the heat transfer element, thereby reducing contact thermal resistance and allowing heat from the heat transfer element to be transferred quickly and evenly to the temperature sensing element. Furthermore, the aforementioned fourth lateral distance between the sensing surface and the third heat dissipation hole not only ensures that the heat generated by the temperature sensing element during operation can be dissipated through the third heat dissipation hole, but also prevents the rapid loss of heat transferred to the heat transfer element through the third heat dissipation hole, which could lead to inaccurate sensing results. This effectively improves the reliability and accuracy of the temperature sensing element.

[0022] For example, in a direction perpendicular to the panel, there is a third distance Z3 between the sensing surface and the peripheral area, and the third distance Z3 is 40mm to 80mm. This third distance range between the sensing surface and the peripheral area not only ensures that the heat generated by the temperature sensor during operation can be dissipated through the third heat dissipation hole located on the peripheral area, but also prevents the heat transferred to the bracket from rapidly dissipating through the third heat dissipation hole located on the peripheral area, thus avoiding inaccurate sensing results from the temperature sensor. This effectively improves the reliability and accuracy of the temperature sensor.

[0023] For example, the projection of the bracket onto the plane of the cavity bottom wall is located in the inner area. In this way, the bracket can be positioned close to the second heat dissipation hole, and the heat transferred to the bracket and the heat generated by the components located on the bracket can be quickly discharged through the second heat dissipation hole, avoiding heat accumulation in the mounting cavity and effectively improving the safety and reliability of the stove.

[0024] For example, there are multiple third heat dissipation holes, which are spaced apart along the width of the bottom shell. In this way, the multiple third heat dissipation holes increase the contact area between heat and the external environment, allowing the heat generated by the thermocouple to be more evenly distributed to the surrounding environment, effectively improving the heat dissipation efficiency of the stove and increasing the stability and lifespan of the stove.

[0041] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0042] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0043] One embodiment of this utility model provides a cooktop 10, which can detect the temperature of the burner head 130 by sensing the temperature of the pot bottom through a temperature sensing element 140. The temperature sensing element 140 is protected from heat and damage, effectively improving its sensitivity and service life, thereby enhancing the safety and reliability of the cooktop 10. The following will describe in detail a cooktop 10 according to an embodiment of this utility model with reference to the accompanying drawings.

[0044] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The cooktop 10 includes a bottom shell 110, a panel 120, a burner head 130, and a temperature sensor 140. The bottom shell 110 encloses an opening to form a mounting cavity 1110. The panel 120 is disposed on the bottom shell 110 and covers the opening. A portion of the burner head 130 is disposed within the mounting cavity 1110. The temperature sensor 140 is connected to the burner head 130 and is located within the mounting cavity 1110. The bottom shell 110 has a cavity bottom wall 1111 opposite to the panel 120. The cavity bottom wall 1111 has a first region 1111a and a second region 1111d. The first region 1111a is further away from the panel 120 than the second region 1111d. The temperature sensor 140 has a sensing surface 1411. In a direction perpendicular to the panel 120, the sensing surface 1411 and the first region 1111a have a first distance Z1, which is 35mm to 80mm.

[0045] Specifically, the panel 120 can be a glass panel or a metal panel. The panel 120 can be covered on the bottom shell 110 to form a mounting cavity 1110. The panel 120 can be provided with through holes (not marked in the diagram). The burner head 130 can be disposed in the mounting cavity 1110, and some of the burner head 130 can extend out of the mounting cavity 1110 through the through holes to heat cookware and other items.

[0046] See Figure 4 The temperature sensing element 140 may include a heat-conducting part 1410, a sensing part 1420 and a signal transmission line 1430. The sensing surface 1411 may be formed on the heat-conducting part 1410. The two ends of the sensing part 1420 may be connected to the heat-conducting part 1410 and the signal transmission line 1430 respectively. The heat-conducting part 1410 can transfer the heat generated by the burner head 130 to the sensing part 1420. The sensing part 1420 can convert the heat into temperature information and transmit it outward via the signal transmission line 1430.

[0047] Furthermore, the heat-conducting part 1410 can be made of a material with good thermal conductivity, such as copper or aluminum. This application does not specifically limit the material of the heat-conducting part 1410; any material with good thermal conductivity is acceptable. Moreover, the shape of the heat-conducting part 1410 can be determined according to different usage scenarios and requirements. For example, the shape of the heat-conducting part 1410 can be circular, square, or irregular, etc. This application does not specifically limit the shape of the heat-conducting part 1410.

[0048] See also Figure 2 and Figure 3An adjacent first region 1111a and a second region 1111d can be formed on the bottom wall 1111 of the cavity. Electronic components can be disposed on the first region 1111a. The distance between the temperature sensing element 140 and the first region 1111a in the vertical direction is greater than the distance between the temperature sensing element 140 and the second region 1111d in the vertical direction, thereby giving the electronic components a larger heat dissipation space and heat dissipation range.

[0049] Specifically, the first distance Z1 ranges from 35 mm to 80 mm, such as 35 mm, 50 mm, 60 mm, 70 mm, and 80 mm. Within this range, heat accumulation near the temperature sensing element 140 is prevented, thus avoiding any impact or damage to it. In one embodiment of this invention, the first distance Z1 is 60 mm. This distance value effectively ensures the detection accuracy and service life of the temperature sensing element 140.

[0050] The cooktop 10 of this invention can detect the temperature of the burner head 130 by sensing the temperature of the pot bottom through the temperature sensing element 140. The temperature sensing element 140 is located within the mounting cavity 1110 and is not affected by the flame. Even when using a pointed-bottom pot, the temperature sensing element 140 will not interfere with the pot, thus expanding the applicability of the cooktop 10. Furthermore, the aforementioned first distance between the sensing surface 1411 and the first region 1111a ensures sufficient heat dissipation space for the temperature sensing element 140, preventing heat generated by the temperature sensing element 140 from accumulating nearby and affecting or damaging it. This effectively improves the detection accuracy and service life of the temperature sensing element 140, enhancing the safety and reliability of the cooktop 10.

[0051] In some embodiments, in conjunction with reference Figure 2 and Figure 3 A controller 180 is disposed within the mounting cavity 1110 at a position corresponding to the first region 1111a. A first heat dissipation hole 20 is provided on the first region 1111a for the controller 180 to dissipate heat. Thus, the first heat dissipation hole 20 can be formed on the first region 1111a, allowing the heat generated by the controller 180 to be dissipated through the hole, preventing heat accumulation from affecting and damaging components such as the controller 180 and the temperature sensing element 140. This effectively improves the detection accuracy of the temperature sensing element 140 and extends the service life of both the temperature sensing element 140 and the controller 180, thereby enhancing the safety and reliability of the stove 10.

[0052] See Figure 2 and Figure 3The cooktop 10 may also include an ignition element 50 electrically connected to a controller 180. The controller 180 can control the ignition element 50 to generate a high-voltage spark to ignite the gas in the burner head 130, thereby enabling the burner head 130 to generate a flame for heating cookware.

[0053] The controller 180 and the first heat dissipation hole 20 can be correspondingly arranged on the first region 1111a so that the heat generated by the controller 180 can be quickly discharged through the first heat dissipation hole 20 along a shorter airflow path, avoiding overheating that may occur in the area near the temperature sensing element 140 and the controller 180 due to heat concentration.

[0054] Specifically, the first heat dissipation hole 20 can be connected to the mounting cavity 1110 to allow the mounting cavity 1110 to communicate with the external environment. The shape and heat dissipation area of ​​the first heat dissipation hole 20 can be determined according to actual usage needs, and this application does not impose specific limitations on them. For example, the shape of the first heat dissipation hole 20 can be elongated or circular, etc.

[0055] In some embodiments, see Figure 3 Along the length of the bottom shell 110, there is a first lateral distance X1 between the sensing surface 1411 and the first heat dissipation hole 20, which is 150mm to 280mm. This first lateral distance range between the sensing surface 1411 and the first heat dissipation hole 20 not only ensures that the heat generated by the temperature sensing element 140 during operation can be dissipated through the first heat dissipation hole 20, but also prevents the heat generated by the burner head 130 from being rapidly lost through the first heat dissipation hole 20, thus avoiding inaccurate sensing results from the temperature sensing element 140. This effectively improves the reliability and accuracy of the temperature sensing element 140.

[0056] Specifically, the first lateral distance X1 ranges from 150 mm to 280 mm, for example, 150 mm, 180 mm, 215 mm, 250 mm, 280 mm, etc. Within this range, the heat generated by the temperature sensing element 140 can be dissipated in a timely manner through the first heat dissipation hole 20, thereby avoiding any impact or damage to the temperature sensing element 140. In one embodiment of this utility model, the first lateral distance X1 is 215 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 140 are well guaranteed.

[0057] It is understandable that the first lateral distance between the sensing surface 1411 and the first heat dissipation hole 20 should not be too large or too small. When the first lateral distance is too large, the heat generated by the temperature sensing element 140 during operation cannot be dissipated through the first heat dissipation hole 20, causing the heat generated by the temperature sensing element 140 to accumulate in the mounting cavity 1110, thereby affecting and damaging the temperature sensing element 140. When the first lateral distance is too small, the heat generated by the burner head 130 may be quickly dissipated through the first heat dissipation hole 20, thereby affecting the sensing result of the temperature sensing element 140. Specifically, it may cause the value sensed by the temperature sensing element 140 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 140.

[0058] In some embodiments, see Figure 3 In the width direction of the bottom shell 110, there is a longitudinal distance Y between the sensing surface 1411 and the first heat dissipation hole 20, which is 30mm to 85mm. This longitudinal distance range between the sensing surface 1411 and the first heat dissipation hole 20 not only ensures that the heat generated by the temperature sensing element 140 during operation can be dissipated through the first heat dissipation hole 20, but also prevents the heat generated by the burner head 130 from being rapidly lost through the first heat dissipation hole 20, thus avoiding inaccurate sensing results from the temperature sensing element 140. This effectively improves the reliability and accuracy of the temperature sensing element 140.

[0059] Specifically, the longitudinal distance Y ranges from 30 mm to 85 mm, for example, 30 mm, 50 mm, 65 mm, 70 mm, 85 mm, etc. Within this range, the heat generated by the temperature sensing element 140 can be dissipated in a timely manner through the first heat dissipation hole 20, thereby avoiding any impact or damage to the temperature sensing element 140. In one embodiment of this utility model, the longitudinal distance Y is 65 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 140 are well guaranteed.

[0060] Understandably, the longitudinal distance between the sensing surface 1411 and the first heat dissipation hole 20 should not be too large or too small. When the longitudinal distance is too large, the heat generated by the temperature sensing element 140 during operation cannot be dissipated through the first heat dissipation hole 20, causing the heat generated by the temperature sensing element 140 to accumulate in the mounting cavity 1110, thereby affecting and damaging the temperature sensing element 140. When the longitudinal distance is too small, the heat generated by the burner head 130 may be quickly dissipated through the first heat dissipation hole 20, thereby affecting the sensing result of the temperature sensing element 140. Specifically, it may cause the value sensed by the temperature sensing element 140 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 140.

[0061] In some embodiments, see Figure 3Multiple first heat dissipation holes 20 are provided, spaced apart along the width of the bottom shell 110. This increases the contact area between heat and the external environment, allowing the heat generated by the controller 180 to be more evenly distributed, effectively improving the heat dissipation efficiency of the cooktop 10 and increasing its stability and lifespan.

[0062] Specifically, the spacing between the plurality of first heat dissipation holes 20 in the width direction of the bottom shell 110 can be determined according to the actual situation or usage requirements, and this application does not impose specific limitations on this. For example, when it is necessary to ensure that the heat dissipation area of ​​the first heat dissipation holes 20 can cover the first region 1111a, the spacing between the plurality of first heat dissipation holes 20 can be 10 mm.

[0063] In some embodiments, in conjunction with reference Figure 2 and Figure 3 The bottom shell 110 has a cavity sidewall 1112, which is located between the cavity bottom wall 1111 and the panel 120. The second region 1111d has an inner region 1111b and an outer region 1111c. The outer region 1111c is closer to the cavity sidewall 1112 than the inner region 1111b. The projection of the temperature sensing element 140 onto the plane of the cavity bottom wall 1111 is located in the inner region 1111b. The inner region 1111b is provided with a second heat dissipation hole 30 for the temperature sensing element 140 to dissipate heat. In this way, the heat generated by the temperature sensing element 140 can be discharged from the mounting cavity 1110 in a timely manner through the second heat dissipation hole 30 provided in the inner region 1111b. Furthermore, the temperature sensing element 140 can be located above the internal area 1111b, so that the hot airflow in the mounting cavity 1110 can be quickly discharged along a shorter airflow path, avoiding overheating that may occur due to heat concentration in the area near the temperature sensing element 140, and further improving the accuracy and service life of the temperature sensing element 140.

[0064] Specifically, the cavity bottom wall 1111 and cavity side wall 1112 of the bottom shell 110 can be detachably connected or integrally formed. The detachable connection can include plug-in connection or adhesive connection, etc., and this application does not make specific limitations in this regard.

[0065] Specifically, the controller 180 can be set to correspond to the first region 1111a, and the temperature sensing element 140 can be set to correspond to the inner region 1111b. Through the first heat dissipation hole 20 set on the first region 1111a and the second heat dissipation hole 30 set on the inner region 1111b, the controller 180 and the temperature sensing element 140 can have different heat dissipation channels, which effectively ensures the heat dissipation effect and heat dissipation efficiency of the stove 10.

[0066] Specifically, the second heat dissipation hole 30 can be connected to the mounting cavity 1110 to allow the mounting cavity 1110 to communicate with the external environment. The shape and heat dissipation area of ​​the second heat dissipation hole 30 can be determined according to actual usage needs, and this application does not impose specific limitations on this. For example, the shape of the second heat dissipation hole 30 can be elongated or circular, etc.

[0067] In an embodiment not shown, there may be multiple second heat dissipation holes 30, and these multiple second heat dissipation holes 30 may be spaced apart on the inner region 1111b.

[0068] In some embodiments, see Figure 5 In a direction perpendicular to the panel 120, there is a second distance Z2 between the sensing surface 1411 and the inner region 1111b, which is 35mm to 75mm. This second distance range between the sensing surface 1411 and the inner region 1111b ensures that the heat generated by the temperature sensor 140 during operation can be dissipated through the second heat dissipation hole 30 located on the inner region 1111b. It also prevents the heat generated by the burner head 130 from rapidly dissipating through the second heat dissipation hole 30 on the inner region 1111b, thus avoiding inaccurate sensing results from the temperature sensor 140. This effectively improves the reliability and accuracy of the temperature sensor 140.

[0069] Specifically, the second distance Z2 ranges from 35 mm to 75 mm, such as 35 mm, 45 mm, 55 mm, 65 mm, and 75 mm. Within this range, the heat generated by the temperature sensing element 140 can be dissipated in a timely manner through the second heat dissipation hole 30, thereby avoiding any impact or damage to the temperature sensing element 140. In one embodiment of this invention, the second distance Z2 is 55 mm. This distance value effectively ensures the detection accuracy and service life of the temperature sensing element 140.

[0070] Understandably, the second distance between the sensing surface 1411 and the internal region 1111b should not be too large or too small. When the second distance is too large, the heat generated by the temperature sensing element 140 during operation cannot be dissipated through the second heat dissipation hole 30 located on the internal region 1111b, causing the heat generated by the temperature sensing element 140 to accumulate in the mounting cavity 1110, thereby affecting and damaging the temperature sensing element 140. When the second distance is too small, the heat generated by the burner head 130 may be quickly dissipated through the second heat dissipation hole 30 located on the internal region 1111b, thereby affecting the sensing result of the temperature sensing element 140. Specifically, it may cause the value sensed by the temperature sensing element 140 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 140.

[0071] In some embodiments, see Figure 2The second heat dissipation hole 30 is a circular hole, and the projection of the sensing surface 1411 onto the plane of the cavity bottom wall 1111 is located inside the circular hole. In this way, the sensing surface 1411 of the temperature sensing element 140 can be located directly above the second heat dissipation hole 30, and the heat generated by the temperature sensing element 140 can be dissipated through the second heat dissipation hole 30 in the first instance, thereby ensuring that the temperature sensing element 140 can always be in a stable and suitable working environment temperature, effectively improving the sensing accuracy and service life of the temperature sensing element 140, and further improving the safety and reliability of the stove 10.

[0072] In some embodiments, in conjunction with reference Figure 3 , Figure 6 , Figure 8 , Figure 9 and Figure 10 The burner head 130 includes an ejector tube 1310 and a support 1320. The ejector tube 1310 is positioned by the support 1320, and a thermocouple 150 is mounted on the support 1320. A third heat dissipation hole 40 for heat dissipation of the thermocouple 150 is provided on the outer periphery 1111c. Thus, by mounting the ejector tube 1310 and the thermocouple 150 on the support 1320, the overall structural design of the burner head 130 can be optimized, making it more compact and stable. Furthermore, the positioning of the ejector tube 1310 and the thermocouple 150 by the support 1320 simplifies the assembly process of the burner head 130, reduces assembly steps and time, and facilitates subsequent maintenance and replacement, greatly reducing maintenance costs. Furthermore, the heat generated by the thermocouple 150 can be discharged through the third heat dissipation hole 40, which avoids the impact and damage to the temperature sensing element 140 and the thermocouple 150 caused by heat accumulation, effectively improving the detection accuracy of the temperature sensing element 140 and the service life of the temperature sensing element 140 and the thermocouple 150, thereby improving the safety and reliability of the stove 10.

[0073] Specifically, the number and type of ejector tubes 1310 can be determined according to the type of burner head 130. Figure 6 For example, Figure 6 The burner head 130 shown is a double-ring burner head. When the burner head 130 is a double-ring burner head, the injector tube 1310 may include an inner ring injector tube 1311 and an outer ring injector tube 1312. When the burner head 130 is a triple-ring burner head, the injector tube 1310 may include an inner ring injector tube 1311, a middle ring injector tube, and an outer ring injector tube 1312. One end of the injector tube 1310 can be connected to a gas source, and the other end of the injector tube 1310 can be threaded onto the bracket 1320.

[0074] See Figure 7The bracket 1320 may have a plate 1321 and a foot 1322. One end of the foot 1322 may be mounted on the plate 1321. The end of the foot 1322 away from the plate 1321 may form a connecting end 1323, which can be fixedly connected to the bottom shell 110 of the stove 10 to fix the burner head 130.

[0075] See also Figure 6 and Figure 7 Thermocouple 150 can be installed on bracket 1320 and located next to temperature sensing element 140. Thermocouple 150 can detect and monitor the combustion status of burner head 130 so as to quickly cut off the gas supply when burner head 130 is accidentally extinguished, and prevent safety accidents caused by gas leakage.

[0076] See again Figure 2 and Figure 3 There can be multiple third heat dissipation holes 40, and these multiple third heat dissipation holes 40 can be spaced apart along the width of the housing to improve the heat dissipation efficiency and effect of the thermocouple 150.

[0077] In some embodiments, in conjunction with reference Figure 3 , Figure 6 , Figure 7 and Figure 8 The temperature sensing element 140 is mounted on the bracket 1320. Thus, by sensing the temperature of the bracket 1320 through the temperature sensing element 140, the temperature of the pot bottom can be detected (i.e., indirectly detecting the pot temperature). This not only ensures that the temperature sensing element 140 can sense the temperature of the pot bottom in real time, but also avoids interference or damage to the temperature sensing element 140 due to its close proximity to the flame of the burner 130. This effectively improves the accuracy of the temperature sensing results, thereby enhancing the safety and reliability of the stove 10.

[0078] The temperature sensor 140 can be mounted on the bracket 1320 so that it can form surface contact with the bracket 1320. When the cookware is heated, the temperature of the bottom of the cookware above the burner 130 can be transferred to the bracket 1320, thus correlating the temperature of the bracket 1320 with the temperature of the bottom of the cookware. Therefore, the temperature sensor 140 can determine the temperature of the bottom of the cookware by sensing the temperature of the bracket 1320. Specifically, the bracket 1320 can be made of a material with good thermal conductivity, such as stainless steel.

[0079] See Figure 7 and Figure 8The temperature sensor 140 can be detachably connected to the bracket 1320 via fasteners 170. The fasteners 170 can be bolts or screws, etc. This detachable connection allows the temperature sensor 140 to be quickly installed on the bracket 1320, effectively saving installation time and costs. Furthermore, when it is necessary to replace or maintain the temperature sensor 140, it can be easily disassembled and assembled, greatly reducing the workload and costs required for disassembly and assembly.

[0080] In embodiments not shown, the temperature sensing element 140 may also be connected to the bracket 1320 by other means, such as welding, riveting, gluing, snap-fit ​​connection, etc.

[0081] In some embodiments, see Figure 3 The sensing surface 1411 forms a surface contact with the bracket 1320. Along the length of the bottom shell 110, there is a second lateral distance X2 between the sensing surface 1411 and the third heat dissipation hole 40, which is 35mm to 75mm. This surface contact significantly increases the contact area between the temperature sensing element 140 and the bracket 1320, thereby reducing contact thermal resistance and allowing heat from the bracket 1320 to be quickly and evenly transferred to the temperature sensing element 140. Furthermore, the aforementioned second lateral distance between the sensing surface 1411 and the third heat dissipation hole 40 not only ensures that the heat generated by the temperature sensing element 140 during operation can be dissipated through the third heat dissipation hole 40, but also prevents the rapid loss of heat transferred to the bracket 1320 through the third heat dissipation hole 40, thus avoiding inaccurate sensing results from the temperature sensing element 140. This effectively improves the reliability and accuracy of the temperature sensing element 140.

[0082] Specifically, the second lateral distance X2 ranges from 35 mm to 75 mm, for example, 35 mm, 45 mm, 55 mm, 65 mm, 75 mm, etc. Within this range, the heat generated by the temperature sensing element 140 can be dissipated in a timely manner through the third heat dissipation hole 40, thereby avoiding any impact or damage to the temperature sensing element 140. In one embodiment of this utility model, the second lateral distance X2 is 55 mm. With this distance value, the detection accuracy and service life of the temperature sensing element 140 are well guaranteed.

[0083] Understandably, the second lateral distance between the sensing surface 1411 and the third heat dissipation hole 40 should not be too large or too small. When the second lateral distance is too large, the heat generated by the temperature sensing element 140 during operation cannot be dissipated through the third heat dissipation hole 40, causing the heat generated by the temperature sensing element 140 to accumulate in the mounting cavity 1110, thereby affecting and damaging the temperature sensing element 140. When the second lateral distance is too small, the heat transferred to the bracket 1320 may be quickly dissipated through the third heat dissipation hole 40, thereby affecting the sensing result of the temperature sensing element 140. Specifically, it may cause the value sensed by the temperature sensing element 140 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 140.

[0084] In some embodiments, see Figure 9 The temperature sensing element 140 is mounted on the ejector tube 1310. By sensing the temperature of the ejector tube 1310 through the temperature sensing element 140, the temperature of the bottom of the pot can be detected (i.e., the temperature of the pot can be detected indirectly). This not only ensures that the temperature sensing element 140 can sense the temperature of the bottom of the pot in real time, but also avoids interference or damage to the temperature sensing element 140 due to the close distance between the temperature sensing element 140 and the flame of the burner 130. This effectively improves the accuracy of temperature sensing by the temperature sensing element 140, thereby improving the safety and reliability of the stove 10.

[0085] Specifically, the ejector tube 1310 may include an inner ring ejector tube 1311 and an outer ring ejector tube 1312, and the temperature sensing element 140 may be attached to one or more of the ejector tubes 1310, preferably attached to the inner ring ejector tube 1311.

[0086] When the cookware is heated, the temperature of the bottom of the pot above the burner head 130 can be transferred to the ejector tube 1310, thus relating the temperature of the ejector tube 1310 to the temperature of the bottom of the pot. Therefore, the temperature sensor 140 can determine the temperature of the burner head 130 by sensing the temperature of the ejector tube 1310. Specifically, the ejector tube 1310 can be made of a heat-conducting material, such as metal or other materials with good heat transfer properties, so that the temperature sensor 140 can sense the temperature of the ejector tube 1310.

[0087] In some embodiments, see Figure 3The sensing surface 1411 forms a surface contact with the ejector tube 1310. Along the length of the bottom shell 110, there is a third lateral distance X3 between the sensing surface 1411 and the third heat dissipation hole 40, ranging from 15mm to 105mm. This surface contact significantly increases the contact area between the temperature sensing element 140 and the ejector tube 1310, thereby reducing contact thermal resistance and allowing heat from the ejector tube 1310 to be quickly and evenly transferred to the temperature sensing element 140. Furthermore, the aforementioned third lateral distance between the sensing surface 1411 and the third heat dissipation hole 40 not only ensures that the heat generated by the temperature sensing element 140 during operation can be dissipated through the third heat dissipation hole 40, but also prevents the rapid loss of heat transferred to the ejector tube 1310 through the third heat dissipation hole 40, which could lead to inaccurate sensing results from the temperature sensing element 140. This effectively improves the reliability and accuracy of the temperature sensing element 140.

[0088] The shape of the heat-conducting portion 1410 of the temperature sensing element 140 can be adapted to the outer contour of the ejector tube 1310. Specifically, the shape of the heat-conducting portion 1410 can be an arc-shaped plate, which not only allows for sufficient contact area between the heat-conducting portion 1410 and the ejector tube 1310, but also ensures that the two are in close contact. The sensing surface 1411 can be formed on the side of the heat-conducting portion 1410 that is in contact with the outer surface of the ejector tube 1310.

[0089] The sensing surface 1411 of the heat-conducting part 1410 and the outer surface of the ejector tube 1310 can be in contact by means of adhesive connection or snap-fit ​​connection. This application does not specifically limit the contact method between the temperature sensing element 140 and the ejector tube 1310.

[0090] Specifically, the value of the third lateral distance X3 ranges from 15 mm to 105 mm, for example, 15 mm, 50 mm, 70 mm, 85 mm, 105 mm, etc. Within this range, the heat generated by the temperature sensing element 140 can be dissipated in a timely manner through the third heat dissipation hole 40, thereby avoiding any impact or damage to the temperature sensing element 140. In one embodiment of this utility model, the third lateral distance X3 is 70 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 140 are well guaranteed.

[0091] Understandably, the third lateral distance between the sensing surface 1411 and the third heat dissipation hole 40 should not be too large or too small. When the third lateral distance is too large, the heat generated by the temperature sensing element 140 during operation cannot be dissipated through the third heat dissipation hole 40, causing the heat generated by the temperature sensing element 140 to accumulate in the mounting cavity 1110, thereby affecting and damaging the temperature sensing element 140. When the third lateral distance is too small, the heat transferred to the ejector tube 1310 may be quickly dissipated through the third heat dissipation hole 40, thereby affecting the sensing result of the temperature sensing element 140. Specifically, it may cause the value sensed by the temperature sensing element 140 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 140.

[0092] In some embodiments, in conjunction with reference Figure 10 and Figure 11 The ejector tube 1310 is connected to a heat transfer element 160, and a temperature sensing element 140 is disposed on the heat transfer element 160. Thus, the temperature sensing element 140 can contact the heat transfer element 160. When the stove 10 is in combustion mode, since the temperature of the heat transfer element 160 is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the heat transfer element 160 through the temperature sensing element 140 (i.e., indirectly detecting the pot temperature). The temperature sensing element 140 is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that even when using a pointed-bottom pot, the temperature sensing element 140 will not interfere with the pot, expanding the applicability of the stove 10 and effectively improving its practicality.

[0093] For a single-ring furnace head, the heat transfer element 160 can be connected to the single ejector tube 1310; for a double-ring furnace head, the heat transfer element 160 can be connected to the inner ring ejector tube 1311, or the heat transfer element 160 can also be connected to the outer ring ejector tube 1312, or the heat transfer element 160 can be connected to both the inner ring ejector tube 1311 and the outer ring ejector tube 1312 simultaneously; for a triple-ring furnace head, the heat transfer element 160 can be connected to at least one of the inner ring ejector tube 1311, the middle ring ejector tube, or the outer ring ejector tube 1312. (See also...) Figure 10 The heat transfer element 160 can be disposed on the inner ring ejector tube 1311. It should be understood that when a pot is placed on the burner head 130, the central area of ​​the pot bottom is typically where heat is concentrated. When there are two or more ejector tubes 1310, the inner ring ejector tube 1311 is closer to the center of the burner head 130, and its temperature better reflects the temperature of the pot bottom. Therefore, connecting the heat transfer element 160 to the inner ring ejector tube 1311 allows the heat transfer element 160 to more accurately reflect the temperature of the pot bottom. In embodiments not shown, the heat transfer element 160 can also be disposed on ejector tubes 1310 other than the inner ring ejector tube 1311.

[0094] Specifically, see Figure 11 The heat transfer element 160 may have a sleeve portion 1610, and the ejector tube 1310 may have a mating section 1313. A through hole (not shown in the figure) may be provided on the sleeve portion 1610. The sleeve portion 1610 can be fitted onto the mating section 1313 through the through hole. To ensure connection stability, the sleeve portion 1610 can also be connected to the mating section 1313 by means of adhesive, welding, or snap-fit. This facilitates the installation of the heat transfer element 160, and because the temperature of the pot bottom above the burner head 130 is transferred to the sleeve portion 1610 through the ejector tube 1310 when the pot is heated, the temperature of the heat transfer element 160 is correlated with the temperature of the pot bottom, ensuring accurate and rapid temperature detection.

[0095] Further, see Figure 11 The outer edge of the sleeve portion 1610 can extend into a plate-shaped portion 1620. The plate-shaped portion 1620 can have a surface to be measured 1630. The temperature sensing element 140 can be attached to the surface to be measured 1630. This facilitates the installation of the temperature sensing element 140, and since the temperature of the pot bottom above the burner 130 is transferred to the plate-shaped portion 1620 through the injector tube 1310 when the pot is heated, the temperature of the plate-shaped portion 1620 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection.

[0096] It should be understood that in this embodiment of the invention, the temperature sensing element 140 indirectly detects the temperature of the pot bottom by detecting the temperature of the heat transfer element 160. To ensure the accuracy of temperature detection, the heat transfer element 160 can be made of a thermally conductive material, such as metal or other materials with good thermal conductivity. Specifically, the heat transfer element 160 and the ejector tube 1310 can be made of the same material, such as stainless steel, thus forming a stainless steel assembly.

[0097] In some embodiments, the sensing surface 1411 forms a surface contact with the heat transfer element 160. Along the length of the bottom shell 110, there is a fourth lateral distance X4 between the sensing surface 1411 and the third heat dissipation hole 40, where the fourth lateral distance X4 is 15mm to 105mm. This surface contact significantly increases the contact area between the temperature sensing element 140 and the heat transfer element 160, thereby reducing contact thermal resistance and allowing heat from the heat transfer element 160 to be quickly and evenly transferred to the temperature sensing element 140. Furthermore, the aforementioned fourth lateral distance between the sensing surface 1411 and the third heat dissipation hole 40 not only ensures that the heat generated by the temperature sensing element 140 during operation can be dissipated through the third heat dissipation hole 40, but also prevents the heat transferred to the heat transfer element 160 from rapidly dissipating through the third heat dissipation hole 40, thus avoiding inaccurate sensing results from the temperature sensing element 140. This effectively improves the reliability and accuracy of the temperature sensing element 140.

[0098] Specifically, the heat-conducting part 1410 of the temperature sensing element 140 can be plate-shaped, and the plate-shaped heat-conducting part 1410 can be in contact with the heat transfer element 160 to achieve surface contact between the two.

[0099] Furthermore, the temperature sensing element 140 and the heat transfer element 160 can be connected by welding, riveting, adhesive bonding or snap-fit ​​connection, etc., and this application does not make specific limitations in this regard.

[0100] Specifically, the fourth lateral distance X4 ranges from 15 mm to 105 mm, for example, 15 mm, 50 mm, 70 mm, 85 mm, 105 mm, etc. Within this range, the heat generated by the temperature sensing element 140 can be dissipated in a timely manner through the third heat dissipation hole 40, thereby avoiding any impact or damage to the temperature sensing element 140. In one embodiment of this utility model, the fourth lateral distance X4 is 70 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 140 are well guaranteed.

[0101] Understandably, the fourth lateral distance between the sensing surface 1411 and the third heat dissipation hole 40 should not be too large or too small. When the fourth lateral distance is too large, the heat generated by the temperature sensing element 140 during operation cannot be dissipated through the third heat dissipation hole 40, causing the heat generated by the temperature sensing element 140 to accumulate in the mounting cavity 1110, which may affect or damage the temperature sensing element 140. When the fourth lateral distance is too small, the heat on the heat transfer element 160 may be quickly dissipated through the third heat dissipation hole 40, thus affecting the sensing result of the temperature sensing element 140. Specifically, it may cause the value sensed by the temperature sensing element 140 to be too low, failing to accurately reflect the actual sensed value, thereby affecting the accuracy of the sensing result of the temperature sensing element 140.

[0102] In some embodiments, see Figure 5 In a direction perpendicular to the panel 120, there is a third distance Z3 between the sensing surface 1411 and the peripheral area 1111c, which is 40mm to 80mm. This third distance range between the sensing surface 1411 and the peripheral area 1111c ensures that the heat generated by the temperature sensor 140 during operation can be dissipated through the third heat dissipation hole 40 located on the peripheral area 1111c. It also prevents the heat transferred to the bracket 1320 from rapidly dissipating through the third heat dissipation hole 40 on the peripheral area 1111c, thus avoiding inaccurate sensing results from the temperature sensor 140. This effectively improves the reliability and accuracy of the temperature sensor 140.

[0103] Specifically, the third distance Z3 ranges from 40 mm to 80 mm, such as 40 mm, 50 mm, 60 mm, 70 mm, and 80 mm. Within this range, the heat generated by the temperature sensing element 140 can be dissipated in a timely manner through the third heat dissipation hole 40, thereby avoiding any impact or damage to the temperature sensing element 140. In one embodiment of this invention, the third distance Z3 is 60 mm. This distance value effectively ensures the detection accuracy and service life of the temperature sensing element 140.

[0104] Understandably, the third distance between the sensing surface 1411 and the peripheral area 1111c should not be too large or too small. When the third distance is too large, the heat generated by the temperature sensing element 140 during operation cannot be dissipated through the third heat dissipation hole 40 located on the peripheral area 1111c, causing the heat generated by the temperature sensing element 140 to accumulate in the mounting cavity 1110, which may affect or damage the temperature sensing element 140. When the third distance is too small, the heat transferred to the bracket 1320 may be quickly dissipated through the third heat dissipation hole 40 located on the peripheral area 1111c, thereby affecting the sensing result of the temperature sensing element 140. Specifically, it may cause the value sensed by the temperature sensing element 140 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 140.

[0105] In some embodiments, in conjunction with reference Figure 2 and Figure 3 The projection of the bracket 1320 onto the plane of the cavity bottom wall 1111 is located in the inner area 1111b. Thus, the bracket 1320 can be positioned close to the second heat dissipation hole 30, allowing heat transferred to the bracket 1320 and heat generated by the components on the bracket 1320 to be quickly dissipated through the second heat dissipation hole 30, preventing heat accumulation in the mounting cavity 1110 and effectively improving the safety and reliability of the stove 10.

[0106] In some embodiments, see Figure 3 Multiple third heat dissipation holes 40 are arranged at intervals along the width of the bottom shell 110. In this way, multiple third heat dissipation holes 40 can increase the contact area between heat and the external environment, so that the heat generated by the thermocouple 150 can be more evenly distributed to the surrounding environment, effectively improving the heat dissipation efficiency of the stove 10, and increasing the stability and service life of the stove 10.

[0107] Specifically, the spacing between the plurality of third heat dissipation holes 40 in the width direction of the bottom shell 110 can be determined according to the actual situation or usage requirements, and this application does not impose specific limitations on this. For example, when it is necessary to ensure that the heat dissipation area of ​​the third heat dissipation holes 40 can cover the peripheral area 1111c, the spacing between the plurality of third heat dissipation holes 40 can be 10 mm.

[0108] In the description of this utility model, it should be understood that the directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" indicate the orientation or positional relationship, which are usually based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0109] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0110] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.
