Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen utensils, in particular to a temperature measuring device and a gas stove. BACKGROUND

[0002] The gas stove is a kitchen utensil that directly heats gas fuel such as liquefied petroleum gas (liquid), artificial gas, and natural gas. With the development of technology, the gas stove has gradually become intelligent, and the intelligent gas stove can have a dry burning prevention function or an intelligent cooking function. The principle is to detect the temperature of the pot by using a sensor, and adjust the size of the gas stove fire according to the detected temperature, so as to realize intelligent control.

[0003] However, the current intelligent gas stove usually measures the temperature of the pot by a temperature measuring probe arranged on the inner side of the burner. When the temperature measuring probe detects the temperature of the bottom of the pot, it is exposed to the flame of the open fire. The temperature detected by the temperature measuring probe is greatly affected by the flame, resulting in inaccurate temperature measurement. Invention content

[0004] Therefore, it is necessary to provide a temperature measuring device and a gas stove that can improve the temperature measurement accuracy.

[0005] The present application provides a temperature measuring device, which comprises a temperature measuring probe, a heat insulation shell, and a liquid cooling part. The heat insulation shell is arranged on the outer periphery of the temperature measuring probe, and the liquid cooling part is arranged on the inner side of the heat insulation shell and in contact with the heat insulation shell.

[0006] When the temperature measuring device is used in a gas stove, the heat insulation shell is arranged on the outer side of the temperature measuring probe, and the liquid cooling part is arranged on the inner side of the heat insulation shell. The heat insulation shell can reduce the heat transfer from the open fire to the temperature measuring probe, and the liquid cooling part can cool the heat insulation shell, thereby reducing the temperature of the space around the temperature measuring probe and reducing the influence of the flame on the temperature measuring probe, thereby improving the temperature measurement accuracy of the temperature measuring probe.

[0007] In one embodiment, the heat insulation shell has an opening at one end, and a heat insulation cover is arranged at the opening. The temperature measuring probe has a temperature measuring end, and the temperature measuring end is arranged in the heat insulation cover and exposed from the outer surface of the heat insulation cover.

[0008] In this way, the heat insulation cover can position the temperature measuring probe, so that the temperature measuring position is fixed. At the same time, the heat insulation cover can reduce the heat transfer from the heat insulation shell to the temperature measuring probe, thereby further reducing the influence of the flame on the temperature measuring probe. The temperature measuring end is arranged in the heat insulation cover and exposed from the outer surface of the heat insulation cover, which facilitates the direct contact between the temperature measuring probe and the pot, thereby making the temperature measurement more accurate.

[0009] In one embodiment, the temperature measuring end is flush with the outer surface of the heat insulation cover.

[0010] In this way, the temperature measuring end can be guaranteed to contact the pot, and the temperature measuring end of the temperature measuring probe is not exposed to the flame, thereby ensuring the accuracy of temperature measurement.

[0011] In one of the embodiments, the thermal conductivity of the heat insulation cover is lower than the thermal conductivity of the heat insulation shell.

[0012] In this way, the heat of the heat insulation shell can be effectively reduced to the temperature measuring probe, thereby ensuring that most of the heat received by the temperature measuring probe comes from the pot.

[0013] In one of the embodiments, the heat insulation cover is aerogel, vacuum insulation board or asbestos.

[0014] These materials have low thermal conductivity and good heat insulation effect.

[0015] In one of the embodiments, the liquid cooling member is provided as a liquid cooling pipeline, the liquid cooling pipeline is connected to a circulating cooling system, and the circulating cooling system provides flowing cooling liquid to the liquid cooling pipeline.

[0016] In this way, the structure of the liquid cooling member is very simple, and the heat of the heat insulation shell can be quickly removed by the flowing cooling liquid, so that the temperature measuring probe is not affected by the high temperature of the external flame.

[0017] In one of the embodiments, the liquid cooling pipeline is spiral and arranged around the circumference of the temperature measuring probe.

[0018] In this way, the liquid cooling pipeline can better separate the temperature measuring probe and the heat insulation shell, and the liquid cooling pipeline and the heat insulation shell have a larger contact area, which can quickly cool the heat insulation shell to keep the inside of the heat insulation shell in a low-temperature environment close to room temperature.

[0019] In one of the embodiments, a heat-conducting material is filled between the liquid cooling member and the inner wall of the heat insulation shell, and the thermal conductivity of the heat-conducting material is greater than that of air.

[0020] The heat-conducting material increases the contact area between the liquid cooling member and the heat insulation shell, thereby more efficiently removing the heat on the heat insulation shell.

[0021] In one of the embodiments, the heat-conducting material is heat-conducting silica gel or aluminum material.

[0022] The heat-conducting silica gel or aluminum material has high thermal conductivity, which can quickly transfer heat to the liquid cooling member, thereby more efficiently cooling the heat insulation shell.

[0023] The application also provides a gas stove, which comprises a stove body, a support, a burner and the above-mentioned temperature measuring device, the support and the burner are arranged on the stove body, and the temperature measuring device is arranged on the inside of the burner.

[0024] Since the gas stove is provided with the temperature measuring device, the temperature measuring of the gas stove is very accurate, so that the intelligent control can be realized accurately. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below in combination with the drawings. In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

Thus, features defined with "first", "second" can include at least one of the features explicitly or implicitly. In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly and specifically limited.

[0034] In the present application, unless otherwise explicitly specified and limited, the "on", "under", "above" and "over" of the first feature to the second feature can be that the first feature is in direct contact with the second feature, or the first feature is indirectly in contact with the second feature through an intermediate medium.

[0035] Unless otherwise defined, all technical and scientific terms used in the specification of the present application have the same meaning as commonly understood by one skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0036] Please refer to Figures 1 to 4 The present application provides a temperature measuring device 100, comprising a temperature measuring probe 110, a heat insulation shell 120 and a liquid cooling member 130, the heat insulation shell 120 is sleeved on the outer circumferential side of the temperature measuring probe 110, and the liquid cooling member 130 is arranged on the inner side of the heat insulation shell 120 and in contact with the heat insulation shell 120 for heat transfer. When the temperature measuring device 100 is used for a gas stove, since the heat insulation shell 120 is arranged on the outer side of the temperature measuring probe 110, and the liquid cooling member 130 is arranged on the inner side of the heat insulation shell 120, the heat insulation shell 120 can reduce the heat transfer from the open flame to the temperature measuring probe 110, and the liquid cooling member 130 can cool the heat insulation shell 120, thereby reducing the temperature of the space around the temperature measuring probe 110 and reducing the influence of the flame on the temperature measuring probe 110, thereby improving the temperature measuring accuracy of the temperature measuring probe 110.

[0037] As Figure 1As shown, the heat insulation shell 120 is provided with an opening 121 at one end, and the opening 121 is provided with a heat insulation cover 140. The temperature measuring probe 110 is provided with a temperature measuring end 111, which is arranged in the heat insulation cover 140 and exposed from the outer surface of the heat insulation cover 140. In this way, the heat insulation cover 140 can position the temperature measuring probe 110, so that the temperature measuring position is fixed. At the same time, the heat insulation cover 140 can reduce the heat transfer from the heat insulation shell 120 to the temperature measuring probe 110, thereby further reducing the influence of the flame on the temperature measuring probe 110. The temperature measuring end 111 is arranged in the heat insulation cover 140 and exposed from the outer surface of the heat insulation cover 140, which facilitates the direct contact between the temperature measuring probe 110 and the pot 500, thereby making the temperature measurement more accurate.

[0038] Further, the temperature measuring end 111 is flush with the outer surface of the heat insulation cover 140. In this way, the temperature measuring end 111 can contact the pot 500, and the temperature measuring end 111 of the temperature measuring probe 110 is not exposed to the flame, thereby ensuring the accuracy of the temperature measurement.

[0039] Further, the heat conductivity coefficient of the heat insulation cover 140 is lower than that of the heat insulation shell 120. In this way, the heat transfer from the heat insulation shell 120 to the temperature measuring probe 110 can be effectively reduced, thereby ensuring that most of the heat received by the temperature measuring probe 110 comes from the pot 500.

[0040] Further, the heat insulation cover 140 is aerogel, vacuum insulation board or asbestos, which has a low heat conductivity coefficient and good heat insulation effect. Of course, the heat insulation cover 140 can also be other materials with a low heat conductivity coefficient.

[0041] As shown in Figure 1 and Figure 3 , the liquid cooling member 130 is arranged as a liquid cooling pipeline, which is connected to a circulating cooling system 160. The circulating cooling system 160 provides flowing cooling liquid to the liquid cooling pipeline. In this way, the liquid cooling member 130 has a very simple structure, and the flowing cooling liquid can timely take away the heat of the heat insulation shell 120, so that the temperature measuring probe 110 will not be affected by the high temperature of the external flame.

[0042] In an embodiment, the cooling liquid is water, which has good cooling effect and low cost. Of course, the cooling liquid can also be other cooling medium.

[0043] The circulating cooling system 160 can adopt air cooling or compressor cooling to cool the cooling liquid passing through the inside of the circulating cooling system 160, which is not limited in the present application.

[0044] Further, please refer to Figure 1 and Figure 2, the liquid cooling pipeline is in a spiral shape and is arranged around the circumference of the temperature measuring probe 110. In this way, the liquid cooling pipeline can better separate the temperature measuring probe 110 and the heat insulation shell 120, and the liquid cooling pipeline and the heat insulation shell 120 have a larger contact area, which can more quickly cool the heat insulation shell 120, so that the inside of the heat insulation shell 120 is kept in a low-temperature environment close to room temperature. Of course, in other embodiments, the liquid cooling pipeline can also be in a serpentine shape or other shapes, as long as the liquid cooling pipeline is arranged around the circumference of the temperature measuring probe 110 and is in contact with the heat insulation shell 120 to transfer heat.

[0045] It is worth mentioning that the “liquid cooling element 130 is in contact with the heat insulation shell 120 to transfer heat” can be that the liquid cooling element 130 is directly in contact with the heat insulation shell 120, or that the liquid cooling element 130 is indirectly in contact with the heat insulation shell 120. When an intermediate element is arranged between the liquid cooling element 130 and the heat insulation shell 120, the intermediate element can realize heat transfer between the liquid cooling element 130 and the heat insulation shell 120, instead of air, that is, the liquid cooling element 130 and the heat insulation shell 120 are indirectly in contact through the intermediate element to realize contact heat transfer.

[0046] Further, the heat insulation shell 120 and the inner wall of the heat insulation shell 120 are filled with a heat-conducting material 150, and the heat-conducting coefficient of the heat-conducting material 150 is greater than that of air. In this way, the heat-conducting material 150 increases the contact area between the liquid cooling element 130 and the heat insulation shell 120, so that the heat on the heat insulation shell 120 can be more efficiently taken away.

[0047] Further, the heat-conducting material 150 is heat-conducting silica gel or aluminum material, and the heat-conducting coefficient of the heat-conducting silica gel or aluminum material is high, which can timely transfer heat to the liquid cooling element 130, so that the heat insulation shell 120 is more efficiently cooled. The heat-conducting silica gel can be arranged between the liquid cooling element 130 and the inner wall of the heat insulation shell 120 by injection molding, and the aluminum material can be arranged between the liquid cooling element 130 and the inner wall of the heat insulation shell 120 by casting, and the present application does not limit this.

[0048] The bottom plate 122 is arranged at the lower end of the heat insulation shell 120, and the temperature measuring probe 110 and the liquid cooling element 130 are arranged through the bottom plate 122. In this way, the heat insulation shell 120 and the temperature measuring probe 110, the liquid cooling element 130, and the heat insulation cover 140 inside the heat insulation shell 120 can form an integral assembly, which is convenient to install.

[0049] Please refer to Figure 3 and Figure 4The application further provides a gas stove, which comprises a stove body 200, a support 300, a burner 400 and the temperature measuring device 100 as described above, the support 300 and the burner 400 are arranged on the stove body 200, and the temperature measuring device 100 is arranged on the inner side of the burner 400. Since the gas stove is provided with the temperature measuring device 100, the temperature measurement of the gas stove is very accurate, so that precise intelligent control can be realized.

[0050] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0051] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, however, it should not be understood as the limitation to the patent application scope. It should be pointed out that, for the ordinary skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
