Description

Technical Field

[0001] This application relates to the technical field of cooking appliances, and particularly to an electric steamer. Background Art

[0002] An electric steamer is a kitchen appliance that uses electric energy to heat water to generate steam for steaming food. Conventional electric steamers generally cook by manually setting the cooking temperature and cooking duration. However, in such a cooking method, it is easy to have a situation where a large amount of ingredients are undercooked and a small amount of ingredients are overcooked. For this reason, the applicant proposed to detect the temperature in the cooking cavity through a temperature measuring device, judge the amount of ingredients according to the detected temperature, and allocate suitable cooking temperature and duration for different amounts of ingredients, so that different amounts of ingredients can all have good cooking effects and avoid the occurrence of undercooked or overcooked ingredients. Therefore, the accuracy of temperature measurement by the temperature measuring device is crucial. However, when the steam in the electric steamer contacts the pot lid or the pot side wall, condensed water will be formed, and the condensed water dripping onto the temperature measuring device will affect the accuracy of temperature measurement. How to reduce the influence of condensed water on the temperature measuring device is a technical problem that needs to be solved urgently. Utility Model Content

[0003] Based on this, it is necessary to provide an electric steamer to reduce the influence of condensed water on the temperature measuring device.

[0004] An electric steamer includes a base, a steaming grid, a steaming lid, and a temperature measuring device. A steam generator is provided in the base, and the steam generator is provided with a steam generating cavity with an upward opening. The steaming grid and the steaming lid are sequentially arranged on the base, and the steaming grid and the steaming lid enclose a cooking cavity. The bottom wall of the steaming grid is provided with a plurality of first through holes, and the first through holes communicate the steam generating cavity and the cooking cavity; the base is provided with a temperature measuring installation part, the temperature measuring installation part is provided with a cavity, the top of the temperature measuring installation part is provided with a temperature measuring outlet, the temperature measuring device is installed in the cavity, the temperature measuring device includes a temperature measuring probe, the temperature measuring probe extends out from the temperature measuring outlet, the bottom wall of the steaming grid is provided with a first temperature measuring avoidance hole communicating with the cooking cavity, the temperature measuring probe and / or the temperature measuring installation part penetrates through the first temperature measuring avoidance hole, and the top of the temperature measuring installation part is provided with a guiding surface, and the guiding surface surrounds the temperature measuring probe.

[0005] The electric steamer provided by this application provides an installation space for the temperature measuring device by setting the temperature measuring installation part, so that only the temperature measuring probe of the temperature measuring device extends out of the temperature measuring installation part, protecting the temperature measuring device and avoiding damage to the temperature measuring device due to being in a high-temperature steam environment for a long time. Since the top of the temperature measuring installation part is provided with a guiding surface, and the guiding surface surrounds the temperature measuring probe, if condensed water drips onto the temperature measuring probe, the condensed water will flow down along the temperature measuring probe and flow away along the guiding surface, thus avoiding the accumulation or condensation of condensed water on the temperature measuring probe and affecting the accuracy of temperature measurement of the temperature measuring probe.

[0006] In one embodiment, from the side of the diversion surface close to the temperature measuring probe to the side far from the temperature measuring probe, the height of the diversion surface gradually decreases.

[0007] In this way, the diversion surface can make the condensed water on it flow away from the temperature measuring probe in time.

[0008] In one embodiment, the included angle between the section plane of the diversion surface at any position and the axis of the temperature measuring probe is θ, and 20° ≤ θ ≤ 60°.

[0009] In this way, the inclination angle of the diversion surface can make the gravity of water greater than the surface tension of water, so as to ensure that the condensed water flows down quickly, ensure a good diversion effect, and at the same time, it will not cause the cross-sectional area of the temperature measuring installation part to be too small and affect the installation of the temperature measuring probe.

[0010] In one embodiment, the temperature measuring probe passes through the first temperature measuring avoidance hole, and there is a gap between the temperature measuring probe and the inner wall of the first temperature measuring avoidance hole.

[0011] In this way, it is avoided that the temperature measuring probe contacts the steaming grid and affects the accuracy of temperature measurement, and the condensed water can flow down through the gap between the temperature measuring probe and the inner wall of the first temperature measuring avoidance hole, avoiding the accumulation of condensed water on the bottom wall of the steaming grid.

[0012] In one embodiment, at least the lower end of the first temperature measuring avoidance hole is set to gradually expand from top to bottom.

[0013] In this way, compared with a through hole with a constant inner diameter, the gap between the inner wall of the first temperature measuring avoidance hole and the temperature measuring probe is larger, which is beneficial to the flow of condensed water from the first temperature measuring avoidance hole.

[0014] In one embodiment, the diversion surface does not contact the inner wall of the first temperature measuring avoidance hole, and the minimum distance between the diversion surface and the inner wall of the first temperature measuring avoidance hole is L1, and 1mm ≤ L1 ≤ 5mm.

[0015] In this way, it can avoid the accumulation of water due to the surface tension effect, and at the same time reduce the influence of steam flowing from the gap between the diversion surface and the inner wall of the first temperature measuring avoidance hole to the first temperature measuring avoidance hole on the temperature measurement of the temperature measuring probe.

[0016] In one embodiment, it further includes a juice receiving tray. The juice receiving tray is arranged on the base and is located below the steaming grid. The juice receiving tray is provided with a second temperature measuring avoidance hole. The part of the temperature measuring installation part provided with the diversion surface passes through the second temperature measuring avoidance hole, and the diversion surface does not contact the inner wall of the second temperature measuring avoidance hole.

[0017] In this way, the juice receiving tray can receive the condensed water flowing down from the steaming grid, preventing the condensed water from falling into the steam generation cavity and causing the water temperature in the steam generation cavity to decrease, thereby affecting the steam effect.

[0018] In one embodiment, the minimum distance between the guiding surface and the inner wall of the second temperature measurement avoidance hole is L2, where 1 mm ≤ L2 ≤ 5 mm.

[0019] In this way, it can not only prevent water from accumulating due to the effect of surface tension, but also reduce the steam flowing from the gap between the guiding surface and the inner wall of the second temperature measurement avoidance hole to the first temperature measurement avoidance hole, thus affecting the temperature measurement of the temperature measurement probe.

[0020] In one embodiment, a water storage cavity for supplying water to the steam generation cavity is further provided in the base. The water storage cavity surrounds the steam generation cavity on the periphery, and the temperature measurement installation part is arranged on one side of the water storage cavity and extends upward from the bottom wall of the water storage cavity.

[0021] In this way, the condensed water flowing down from the first temperature measurement avoidance hole is guided by the guiding surface to flow downward, and then flows down along the side wall of the temperature measurement installation part into the water storage cavity, so that the condensed water can be reused.

[0022] In one embodiment, the length of the temperature measurement probe extending into the cooking cavity is L, where 0 ≤ L ≤ 50 mm.

[0023] In this way, it is ensured that the temperature detected by the temperature measurement probe is the temperature in the cooking cavity. While ensuring the accuracy of the measured temperature, the consumables of the temperature measurement probe are not too much, thus effectively controlling the cost. Description of the Drawings

Detailed Description of the Invention

[0032] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be made with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application.

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0037] Please refer to Figures 1 to 5, this application provides an electric steamer, which includes a base 10, a steaming grid 20, a steaming lid 70 and a temperature measuring device 30. A steam generator 40 is provided inside the base 10, and the steam generator 40 is provided with a steam generating cavity 41 with an upward opening. The steaming grid 20 and the steaming lid 70 are sequentially arranged on the base 10, and the steaming grid 20 and the steaming lid 70 enclose a cooking cavity 23. A plurality of first through holes 211 are provided on the bottom wall of the steaming grid 20, and the first through holes 211 communicate the steam generating cavity 41 and the cooking cavity 23. In this way, the steam generated in the steam generating cavity 41 can enter the cooking cavity 23 through the first through holes 211 to cook the food. The base 10 is provided with a temperature measuring installation part 15, and a cavity 151 is provided inside the temperature measuring installation part 15. A temperature measuring outlet 152 is provided at the top of the temperature measuring installation part 15, and the temperature measuring device 30 is installed in the cavity 151. The temperature measuring device 30 includes a temperature measuring probe 31, and the temperature measuring probe 31 extends out from the temperature measuring outlet 152. A first temperature measuring avoidance hole 212 communicating with the cooking cavity 23 is provided on the bottom wall of the steaming grid 20, and the temperature measuring probe 31 and / or the temperature measuring installation part 15 penetrate through the first temperature measuring avoidance hole 212. In this way, the temperature measuring probe 31 can detect the temperature inside the cooking cavity 23. A diversion surface 153 is provided at the top of the temperature measuring installation part 15, and the diversion surface 153 is arranged around the temperature measuring probe 31. By providing the temperature measuring installation part 15 to provide an installation space for the temperature measuring device 30, only the temperature measuring probe 31 of the temperature measuring device 30 extends out of the temperature measuring installation part 15, protecting the temperature measuring device 30 and preventing the temperature measuring device 30 from being damaged due to being in a high-temperature steam environment for a long time. Since the diversion surface 153 is provided at the top of the temperature measuring installation part 15 and the diversion surface 153 is arranged around the temperature measuring probe 31, if condensed water drops onto the temperature measuring probe 31, the condensed water will flow down along the temperature measuring probe 31 and flow away along the diversion surface 153, thus avoiding the accumulation or condensation of condensed water on the temperature measuring probe 31 and affecting the accuracy of temperature measurement of the temperature measuring probe 31.

[0038] The top end of the temperature measuring probe 31 extends to the first temperature measuring avoidance hole 212 or the cooking cavity 23. The temperature measuring installation part 15 can be entirely located below the first temperature measuring avoidance hole 212, or partially extend into the first temperature measuring avoidance hole 212, or penetrate through the first temperature measuring avoidance hole 212 and extend into the cooking cavity 23. As long as the top end of the temperature measuring probe 31 extends to the first temperature measuring avoidance hole 212 or the cooking cavity 23 to ensure that the temperature measuring probe 31 can detect the temperature inside the cooking cavity 23.

[0039] Further, please refer to Figure 4, the length of the temperature measuring probe 31 extending into the cooking cavity 23 is L. If L = 0, the top end of the temperature measuring probe 31 is flush with the bottom wall of the cooking cavity 23, that is, the top end of the temperature measuring probe 31 just extends to the cooking cavity 23; if L < 0, the top end of the temperature measuring probe 31 extends to the first temperature measuring avoidance hole 212 and does not extend to the cooking cavity 23; if L > 0, the top end of the temperature measuring probe 31 extends into the cooking cavity 23. In this embodiment, 0 ≤ L ≤ 50 mm, ensuring that the temperature detected by the temperature measuring probe 31 is the temperature inside the cooking cavity 23. While ensuring the accuracy of the measured temperature, the temperature measuring probe 31 does not consume too much material, thus effectively controlling the cost. In some specific embodiments, L can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 12 mm, 15 mm, 16 mm, 18 mm, 20 mm, 22 mm, 25 mm, 26 mm, 28 mm, 30 mm, 32 mm, 35 mm, 36 mm, 38 mm, 40 mm, 42 mm, 45 mm, 46 mm, 48 mm, 50 mm, or any other value within the range of 0 ≤ L ≤ 50 mm.

[0040] In this embodiment, the temperature measuring probe 31 is columnar, but not limited thereto. The temperature measuring probe 31 can also be disc-shaped, and this application does not limit this.

[0041] Furthermore, from the side of the diversion surface 153 close to the temperature measuring probe 31 to the side far from the temperature measuring probe 31, the height of the diversion surface 153 gradually decreases. In this way, the diversion surface 153 can make the condensed water on it flow away in a timely manner in the direction away from the temperature measuring probe 31.

[0042] Furthermore, please refer to Figure 5 , the included angle between the section plane of the diversion surface 153 at any position and the axis of the temperature measuring probe 31 is θ, and 20° ≤ θ ≤ 60°. If this included angle θ is too large, the diversion effect is not good, and the condensed water is likely to accumulate on the diversion surface 153 or even around the temperature measuring probe 31; if this included angle θ is too small, the cross-sectional area of the temperature measuring installation part 15 is small, and it is not easy to install the temperature measuring probe 31. In this embodiment, 20° ≤ θ ≤ 60°, and the inclination angle of the diversion surface 153 can make the gravity of water greater than the surface tension of water, thereby ensuring that the condensed water flows down quickly and ensuring a good diversion effect. Moreover, it will not cause the cross-sectional area of the temperature measuring installation part 15 to be too small and affect the installation of the temperature measuring probe 31. In some specific embodiments, the included angle θ can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, or any other value within the range of 20° ≤ θ ≤ 60°.

[0043] Please refer to Figure 5, in this embodiment, the flow guiding surface 153 includes a conical surface 1531 and a spherical surface 1532. The conical surface 1531 is located above, and the spherical surface 1532 is connected to the lower end of the conical surface 1531. The structure of the flow guiding surface 153 is very simple and the flow guiding effect is good. Of course, the flow guiding surface 153 can also be in other forms, as long as the flow guiding surface 153 can timely guide the condensed water thereon away.

[0044] Further, please refer to Figure 4 , the temperature measuring probe 31 is inserted through the first temperature measuring avoidance hole 212, and there is a gap between the temperature measuring probe 31 and the inner wall of the first temperature measuring avoidance hole 212, which avoids the temperature measuring probe 31 contacting the steaming grid 20 and affecting the accuracy of temperature measurement, and the condensed water can flow down through the gap between the temperature measuring probe 31 and the inner wall of the first temperature measuring avoidance hole 212, avoiding the accumulation of condensed water on the bottom wall of the steaming grid 20.

[0045] Further, please refer to Figure 4 , at least the lower end of the first temperature measuring avoidance hole 212 is set to gradually expand from top to bottom. In this way, compared with a through hole with a constant inner diameter, the gap between the inner wall of the first temperature measuring avoidance hole 212 and the temperature measuring probe 31 is larger, which is beneficial to the condensed water flowing away from the first temperature measuring avoidance hole 212.

[0046] Further, please refer to Figure 4 , the flow guiding surface 153 does not contact the inner wall of the first temperature measuring avoidance hole 212, and the minimum distance between the flow guiding surface 153 and the inner wall of the first temperature measuring avoidance hole 212 is L1, where 1mm ≤ L1 ≤ 5mm. If L1 is too small, the water tension effect is likely to cause water to accumulate at this minimum distance position; if L1 is too large, it will cause the steam below the bottom wall of the steaming grid 20 to flow to the temperature measuring probe 31 through this position without passing through the food materials, thus affecting the accuracy of temperature measurement judgment. In this embodiment, 1mm ≤ L1 ≤ 5mm can both avoid the accumulation of water due to the tension effect and reduce the steam flowing from the gap between the flow guiding surface 153 and the inner wall of the first temperature measuring avoidance hole 212 to the first temperature measuring avoidance hole 212 and affecting the temperature measurement of the temperature measuring probe 31.

[0047] Please refer to Figure 1 , in this embodiment, the steaming grid 20 is of a disk-like structure, that is, equivalent to the bottom part of a steamer with a bottomless steamer basket. The steaming grid 20 is used in cooperation with the bottomless steamer basket 80 to expand the capacity of the cooking cavity. As Figure 1 shown, this electric steamer includes a plurality of steaming grids 20 and a plurality of bottomless steamer baskets 80, and the plurality of steaming grids 20 and the plurality of bottomless steamer baskets 80 are stacked in sequence. The steaming lid 70 covers the uppermost steaming grid 20. Of course, the steaming lid can also cover the uppermost bottomless steamer basket. In other embodiments, the steaming grid 20 can also include an integrated bottom wall and side wall, that is, a steamer with a bottom as commonly referred to.

[0048] Further, please refer to Figures 1 to 4, the electric steamer further includes a juice receiving tray 50. The juice receiving tray 50 is disposed on the base 10 and is located below the steaming grid 20. The juice receiving tray 50 is provided with a second temperature measurement avoidance hole 541, and a part of the temperature measurement installation part 15 having a guiding surface 153 penetrates through the second temperature measurement avoidance hole 541, and the guiding surface 153 does not contact the inner wall of the second temperature measurement avoidance hole 541. In this way, the juice receiving tray 50 can receive the condensed water flowing down from the steaming grid 20, preventing the condensed water from falling into the steam generating chamber 41 and causing the water temperature in the steam generating chamber 41 to decrease, thereby affecting the steam effect.

[0049] Please refer to Figures 1 to 4 , the juice receiving tray 50 includes a juice receiving bottom wall 51 and a juice receiving side wall 52. The juice receiving bottom wall 51 and the juice receiving side wall 52 enclose a juice receiving cavity 512. A boss 53 protruding upward is provided in the central area of the juice receiving bottom wall 51. The boss 53 is located directly above the steam generating chamber 41, and a second through hole 531 for steam to pass through is provided on the top surface of the boss 53. The top end of the juice receiving side wall 52 is further provided with an outwardly turned edge 54, and the second temperature measurement avoidance hole 541 is provided in the outwardly turned edge 54 of the juice receiving side wall 52. In this way, the juice receiving tray 50 receives the condensed water flowing down from the steaming grid 20 through the juice receiving cavity 512. At the same time, the juice receiving tray 50 can also change the flow direction of the steam, so that the steam is concentrated to pass through the second through hole 531 in the central area of the juice receiving tray 50 and flows to the steaming grid 20, reducing the steam flowing directly from below the steaming grid 20 to the temperature measurement probe 31.

[0050] Further, please refer to Figure 4 , the minimum distance between the guiding surface 153 and the inner wall of the second temperature measurement avoidance hole 541 is L2, and 1mm ≤ L2 ≤ 5mm. If L2 is too small, the surface tension of water is likely to cause water to accumulate at this minimum distance position, resulting in the condensed water not flowing smoothly from the guiding surface 153; if L2 is too large, the steam below the juice receiving tray 50 will flow to the temperature measurement probe 31 through this position without passing through the food materials, thus affecting the accuracy of temperature measurement judgment. In this embodiment, 1mm ≤ L2 ≤ 5mm can both prevent water from accumulating due to surface tension and reduce the steam flowing from the gap between the guiding surface 153 and the inner wall of the second temperature measurement avoidance hole 541 to the first temperature measurement avoidance hole 212 and affecting the temperature measurement of the temperature measurement probe 31.

[0051] Further, please refer to Figures 1 to 3 , a water storage cavity 12 for supplying water to the steam generating chamber 41 is further provided in the base 10. The water storage cavity 12 surrounds the periphery of the steam generating chamber 41. A ring-shaped partition 55 is provided on the lower surface of the bottom wall of the juice receiving tray 50. When the juice receiving tray 50 is placed on the base 10, the partition 55 is sleeved outside the side wall of the steam generating chamber 41. In this way, the partition 55 can change the flow path of the steam flowing radially outward below the juice receiving bottom wall 51, so that this part of the steam flows to the bottom wall of the water storage cavity 12, and the water in the water storage cavity 12 can play a sealing role to block the steam from flowing from below the juice receiving bottom wall 51 to the temperature measurement probe 31.

[0052] In this embodiment, the water storage cavity 12 supplies water to the steam generation cavity 41, and the water storage cavity 12 and the steam generation cavity 41 can be connected through the principle of communicating vessels. Please refer to Figure 2 and Figure 6 . Specifically, a water flow channel and a water control valve 60 for controlling the on-off of the water flow channel are provided between the water storage cavity 12 and the steam generation cavity 41. When the water level in the steam generation cavity 41 rises to a preset water level (such as Figure 6 the B water level line shown), the water control valve 60 closes the water flow channel, so that the water storage cavity 12 will not continue to supply water to the steam generation cavity 41; when the water level in the steam generation cavity 41 drops due to evaporation, the water control valve 60 opens the water flow channel, so that the water in the water storage cavity 12 flows into the steam generation cavity 41 for water replenishment. When the water level in the steam generation cavity 41 rises to the preset water level again, the water control valve 60 closes the water flow channel. In this way, the water control valve 60 can keep the water level in the steam generation cavity 41 at a constant height. This connection method not only solves the influence of different water addition amounts of users on temperature measurement and judgment using the temperature measurement probe 31, but also the water level in the steam generation cavity 41 can be controlled at a lower level, which can achieve the purpose of quickly generating steam at a low water level and saves the cooking time of ingredients.

[0053] Furthermore, please refer to Figures 2 to 4 . The temperature measurement installation part 15 is arranged on one side of the water storage cavity 12 and extends upward from the bottom wall of the water storage cavity 12. In this way, the condensed water flowing down from the first temperature measurement avoidance hole 212 is guided downward through the guide surface 153 and then flows down along the side wall of the temperature measurement installation part 15 into the water storage cavity 12, so that the condensed water can be reused.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0055] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these 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.
