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. Traditional 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 a good cooking effect and avoid the occurrence of undercooked or overcooked ingredients. However, the steam of the electric steamer needs to contact the temperature measuring device after absorbing heat from the ingredients to achieve the purpose of accurate temperature measurement and quantity judgment. "Temperature measurement and quantity judgment" refers to judging the amount of ingredients according to the measured temperature. Therefore, how to set the position of the temperature measuring device to improve the accuracy of temperature measurement and quantity judgment is a technical problem that urgently needs to be solved. Utility Model Content

[0003] Based on this, it is necessary to provide an electric steamer to improve the accuracy of temperature measurement and quantity judgment.

[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 temperature measuring device is arranged in the base, and the temperature measuring device includes a temperature measuring probe. At least part of the temperature measuring probe protrudes from the top end of the side wall of the base, and a first temperature measurement avoidance hole is provided in the bottom wall of the steaming grid near the edge area, and the first temperature measurement avoidance hole communicates with the cooking cavity, and the top end of the temperature measuring probe extends into the first temperature measurement avoidance hole or the cooking cavity.

[0005] In the electric steamer provided by this application, by providing a first temperature measurement avoidance hole in the bottom wall of the steaming grid near the edge area, the first temperature measurement avoidance hole communicates with the cooking cavity, and the top end of the temperature measuring probe extends into the first temperature measurement avoidance hole or the cooking cavity. The steam enters the cooking cavity from the first through hole, contacts the temperature measuring probe of the temperature measuring device after absorbing heat from the ingredients, so that the steam detected by the temperature measuring probe is the steam after absorbing heat from the ingredients, and thus the amount of ingredients can be accurately judged according to the detection of the temperature measuring probe, greatly improving the accuracy of temperature measurement and quantity judgment.

[0006] In one embodiment, the base is provided with a temperature measurement mounting portion, the temperature measurement mounting portion is provided with a cavity, the top of the temperature measurement mounting portion is provided with a temperature measurement outlet, the temperature measurement device is installed in the cavity, and at least a part of the temperature measurement probe extends out from the temperature measurement outlet.

[0007] In this way, by providing the temperature measurement mounting portion to provide an installation space for the temperature measurement device, the temperature measurement device only has the temperature measurement probe extending out of the temperature measurement mounting portion, protecting the temperature measurement device and preventing the temperature measurement device from being damaged due to being in a high-temperature steam environment for a long time.

[0008] In one embodiment, there is a gap between the temperature measurement probe and the inner wall of the first temperature measurement avoidance hole.

[0009] In this way, it can be avoided that the temperature measurement probe contacts the bottom wall of the steaming grid, resulting in inaccurate temperature measurement.

[0010] In one embodiment, a juice receiving tray is provided between the base and the steaming grid. The juice receiving tray is provided with a second through hole facing the steam generating cavity and a second temperature measurement avoidance hole for the temperature measurement probe to pass through.

[0011] In this way, by providing the juice receiving tray to receive the condensed water flowing down from the cooking cavity, it is avoided that the condensed water falls into the steam generating cavity, resulting in a decrease in the water temperature in the steam generating cavity and thus affecting the steam effect. The second through hole is provided to ensure that the steam flows upward intensively and flows to the steaming grid, and the second temperature measurement avoidance hole avoids the juice receiving tray from hindering the temperature measurement of the temperature measurement probe.

[0012] In one embodiment, the juice receiving tray includes a juice receiving bottom wall and a juice receiving side wall surrounding the juice receiving bottom wall. The juice receiving bottom wall and the juice receiving side wall enclose a juice receiving cavity. The top end of the juice receiving side wall is further provided with an outward turning edge. The second through hole is provided on the juice receiving bottom wall, and the second temperature measurement avoidance hole is provided on the outward turning edge of the juice receiving side wall.

[0013] In this way, the condensed water flowing down from the steaming grid is received by the juice receiving cavity. The second temperature measurement avoidance hole is provided on the outward turning edge of the juice receiving side wall, which is beneficial to shortening the distance between the part of the juice receiving tray for the temperature measurement probe to pass through and the steaming grid. Thus, the juice receiving side wall close to the outward turning edge plays a certain role in blocking the steam, and the steam flowing from below the steaming grid to the first temperature measurement avoidance hole can be reduced.

[0014] In one embodiment, a baffle extending downward is provided on the lower surface of the bottom wall of the steaming grid. When the juice receiving tray is placed on the base, the baffle is close to the temperature measurement probe and is located inside the juice receiving side wall.

[0015] After the steam flows through the second through-hole and reaches above the juice collecting tray, the steam will not only continue to flow upward through the first through-hole and enter the cooking cavity, but also diffuse around and fill the space between the bottom wall of the steaming grid and the juice collecting tray, and will further diffuse toward the first temperature measurement avoidance hole. In this embodiment, by providing a baffle, the path for the steam to flow toward the first temperature measurement avoidance hole becomes longer, so that the steam directly flowing from below the bottom wall of the steaming grid to the first temperature measurement avoidance hole can be reduced, thereby further improving the accuracy of the temperature measurement and judgment of the temperature measurement device.

[0016] In one embodiment, the distance between the lower end of the baffle and the bottom wall of the juice collecting tray is H1, where 0 < H1 ≤ 5 mm.

[0017] In this way, it is ensured that the baffle has a good effect on blocking the steam, and there will be no assembly interference between the juice collecting tray and the steaming grid, resulting in air leakage.

[0018] In one embodiment, the distance between the part of the top end of the juice collecting side wall provided with the outward turning edge and the lower surface of the bottom wall of the steaming grid facing it is H2, where 0 < H2 ≤ 5 mm.

[0019] In this way, it is ensured that the part of the top end of the juice collecting side wall provided with the outward turning edge has a good effect on blocking the steam, and there will be no assembly interference between the juice collecting tray and the steamer, resulting in air leakage.

[0020] In one embodiment, a water storage cavity for supplying water to the steam generating cavity is further provided in the base. The water storage cavity surrounds the steam generating cavity on the periphery. A ring-shaped partition is provided on the lower surface of the bottom wall of the juice collecting tray. When the juice collecting tray is placed on the base, the partition is sleeved outside the side wall of the steam generating cavity.

[0021] In this way, the partition can change the flow path of the steam flowing around below the bottom wall of the juice collecting tray, so that this part of the steam flows to the bottom wall of the water storage cavity, and the water in the water storage cavity can play a sealing role to block the steam from flowing from below the bottom wall of the juice collecting tray to the temperature measurement probe.

[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 will not be too much, thereby effectively controlling the cost.

[0036] Please refer to Figures 1 to 4, this application provides an electric steamer, including: 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 temperature measuring device 30 is arranged inside the base 10, and the temperature measuring device 30 includes a temperature measuring probe 31, and at least part of the temperature measuring probe 31 protrudes from the top end of the side wall of the base 10. A first temperature measuring avoidance hole 212 is provided in the bottom wall of the steaming grid 20 near the edge area, and the first temperature measuring avoidance hole 212 communicates with the cooking cavity 23. The top end of the temperature measuring probe 31 extends into the first temperature measuring avoidance hole 212 or the cooking cavity 23. In this way, in this application, by providing the first temperature measuring avoidance hole 212 in the bottom wall of the steaming grid 20 near the edge area, the first temperature measuring avoidance hole 212 communicates with the cooking cavity 23, and the top end of the temperature measuring probe 31 extends into the first temperature measuring avoidance hole 212 or the cooking cavity 23. The steam enters the cooking cavity 23 from the first through holes 211, contacts the temperature measuring probe 31 of the temperature measuring device 30 after being absorbed by the food materials, so that the steam detected by the temperature measuring probe 31 is the steam after being absorbed by the food materials, and thus the amount of the food materials can be accurately judged according to the detection of the temperature measuring probe 31, greatly improving the accuracy of temperature measurement and quantity judgment.

[0037] 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 into the cooking cavity 23; if L < 0, the top end of the temperature measuring probe 31 extends into the first temperature measuring avoidance hole 212 and does not extend into 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 of the steam in the cooking cavity 23 after being absorbed by the food materials. While ensuring the accuracy of the measured temperature, the temperature measuring probe 31 will 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.

[0038] In this embodiment, the temperature measurement probe 31 is columnar, but it is not limited thereto. The temperature measurement probe 31 can also be disc-shaped, and this application does not limit this.

[0039] Please refer to Figures 1 to 4 , further, the base 10 is provided with a temperature measurement installation part 15. In one embodiment, the temperature measurement installation part 15 is located below the steaming grid 20 (as Figure 3 shown), but it is not limited thereto. The temperature measurement installation part 15 can also partially extend into the first temperature measurement avoidance hole 212 (as Figure 4 shown), or the temperature measurement installation part can also partially pass through the first temperature measurement avoidance hole and extend into the cooking cavity. A cavity 151 is provided in the temperature measurement installation part 15, and a temperature measurement outlet 152 is provided at the top of the temperature measurement installation part 15. The temperature measurement device 30 is installed in the cavity 151, and at least a part of the temperature measurement probe 31 extends out from the temperature measurement outlet 152. By providing the temperature measurement installation part 15 to provide an installation space for the temperature measurement device 30, only the temperature measurement probe 31 of the temperature measurement device 30 extends out of the temperature measurement installation part 15, protecting the temperature measurement device 30 and avoiding damage to the temperature measurement device 30 due to being in a high-temperature steam environment for a long time.

[0040] Further, please refer to Figure 4 , there is a gap between the temperature measurement probe 31 and the inner wall of the first temperature measurement avoidance hole 212. In this way, it can be avoided that the temperature measurement probe 31 contacts the bottom wall of the steaming grid 20, resulting in inaccurate temperature measurement.

[0041] Further, there is a gap between the temperature measurement installation part 15 and the bottom wall of the steaming grid 20. In this way, the condensed water can flow down through this gap, thereby avoiding the accumulation of condensed water on the temperature measurement probe 31 and affecting the accuracy of temperature measurement. However, due to the gap, the steam in the steam generation cavity 41 can enter the first temperature measurement avoidance hole 212 from below the steaming grid 20 and enter the cooking cavity 23 through the first temperature measurement avoidance hole 212. Figure 4 The path indicated by the arrow in

[0042] Please refer to Figures 1 to 4, a juice receiving tray 50 is provided between the base 10 and the steaming grid 20. The juice receiving tray 50 is provided with a second through hole 531 facing the steam generating cavity 41 and a second temperature measuring avoidance hole 541 for the temperature measuring probe 31 to pass through. In this way, by setting the juice receiving tray 50 to receive the condensed water flowing down from the cooking cavity, it is avoided that the condensed water falls into the steam generating cavity 41, resulting in a decrease in the water temperature in the steam generating cavity 41, thereby affecting the steam effect. The second through hole 531 is provided to ensure that the steam flows upward centrally and towards the steaming grid 20, and the second temperature measuring avoidance hole 541 prevents the juice receiving tray 50 from obstructing the temperature measurement of the temperature measuring probe 31.

[0043] In this embodiment, the temperature measuring installation part 15 partially passes through the second temperature measuring avoidance hole 541. Of course, in other embodiments, the temperature measuring installation part 15 may also be located below the second temperature measuring avoidance hole 541.

[0044] Furthermore, the juice receiving tray 50 includes a juice receiving bottom wall 51 and a juice receiving side wall 52 surrounding the juice receiving bottom wall 51. The juice receiving bottom wall 51 and the juice receiving side wall 52 enclose a juice receiving cavity 512. The top end of the juice receiving side wall 52 is further provided with an outwardly turned edge 54. The second through hole 531 is provided on the juice receiving bottom wall 51, and the second temperature measuring avoidance hole 541 is provided on the outwardly turned edge 54 of the juice receiving side wall 52. In this way, the condensed water flowing down from the steaming grid 20 is received through the juice receiving cavity 512. The second temperature measuring avoidance hole 541 is provided on the outwardly turned edge 54 of the juice receiving side wall 52, which is beneficial to shortening the distance between the part of the juice receiving tray 50 through which the temperature measuring probe 31 passes and the steaming grid 20. Thus, the juice receiving side wall 52 near the outwardly turned edge 54 plays a certain blocking role on the steam, and the steam flowing from below the steaming grid 20 to the first temperature measuring avoidance hole 212 can be reduced.

[0045] Furthermore, a boss 53 protrudes upward from the central area of the juice receiving bottom wall 51, and the second through hole 531 is provided on the top surface of the boss 53. In this way, the boss 53 can prevent the condensed water in the juice receiving tray 50 from flowing back into the steam generating cavity 41 through the second through hole 531, thereby avoiding the decrease in the water temperature in the steam generating cavity 41 and affecting the steam effect.

[0046] A water storage cavity 12 for supplying water to the steam generating cavity 41 is further provided in the base 10. The water storage cavity 12 surrounds the steam generating cavity 41 on the peripheral side. 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 cavity 41. In this way, the partition 55 can change the flow path of the steam flowing around the lower part of the bottom wall of the juice receiving tray 50, so that this part of the steam flows towards 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 bottom wall of the juice receiving tray 50 to the temperature measuring probe 31.

[0047] In this embodiment, the water storage cavity 12 supplies water to the steam generating cavity 41, and the water storage cavity 12 and the steam generating cavity 41 can be connected through the principle of communicating vessels. Please refer toFigure 2 and Figure 5 , 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, 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 to achieve water replenishment. When the water level in the steam generation cavity 41 rises to the preset water level again (such as Figure 5 the B water level line shown), the water control valve 60 closes the water flow channel. Repeating this cycle, 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 the 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.

[0048] Please refer to Figures 1 to 4 , further, a baffle 213 extending downward is provided on the lower surface of the bottom wall of the steaming grid 20. When the juice receiving tray 50 is placed on the base 10, the baffle 213 is close to the temperature measurement probe 31 and is located inside the side wall 52 of the juice receiving tray. Since the steam flows through the second through hole 531 to the upper part of the juice receiving tray 50, the steam will not only continue to flow upward through the first through hole 211 into the cooking cavity 23, but also diffuse around and fill the space between the bottom wall of the steaming grid 20 and the juice receiving tray 50, and will further diffuse toward the first temperature measurement avoidance hole 212. As Figure 4 shown, the arrow indicates the flow path of the steam below the bottom wall of the steaming grid 20. In this embodiment, by providing the baffle 213, the flow path of the steam flowing toward the first temperature measurement avoidance hole 212 becomes longer, so that the steam directly flowing from below the bottom wall of the steaming grid 20 to the first temperature measurement avoidance hole 212 can be reduced, thereby further improving the accuracy of the temperature measurement and judgment of the temperature measurement device 30.

[0049] In summary, the juice receiving tray 50 can not only receive the condensed water to prevent the condensed water from falling back into the steam generation cavity 41, but also change the flow path of the steam. As Figure 3 shown, it is a schematic diagram of the steam flow path when the electric steam cooker is in use. By providing the above-mentioned juice receiving tray 50, the steam generated in the steam generation cavity 41 can flow along Figure 3Path flows such as the a→b path, c→d path, e→f→d path, etc. exist therein. Among them, the a→b path is the path for steam to directly reach the water storage cavity 12 from the steam generation cavity 41. This path is achieved by setting a partition plate 55. The partition plate 55 introduces steam into the water storage cavity 12, and the water in the water storage cavity 12 blocks the steam from reaching the temperature measuring probe 31 below the juice receiving tray 50. The c→d path is the normal steam path for cooking ingredients. The steam in the steam generation cavity 41 passes through the second through hole 531 to reach below the steaming grid 20, and then passes through the first through hole 211 to reach the cooking cavity 23. After the ingredients absorb heat, it reaches the temperature measuring probe 31. The e→f→d path is the path for steam to directly reach the temperature measuring probe 31 without passing through the ingredients to absorb heat. The steam in the steam generation cavity 41 passes through the second through hole 531 to reach below the steaming grid 20, then diffuses around, and reaches the temperature measuring probe 31 after passing through the gap between the steaming grid 20 and the juice receiving tray 50. It can be seen that the e→f→d path will affect the temperature measurement accuracy of the temperature measuring probe 31. In this application, by setting a baffle 213 and a juice receiving side wall 52 corresponding to the baffle 213, this path is extended, thereby reducing or even blocking the steam reaching the temperature measuring probe 31 through this path, thus improving the accuracy of temperature measurement judgment.

[0050] Further, please refer to Figure 4 As shown in the figure, the distance between the lower end of the baffle 213 and the juice receiving bottom wall 51 is H1, where 0 < H1 ≤ 5 mm. If the distance H1 between the lower end of the baffle 213 and the juice receiving bottom wall 51 is too large, there is no obvious effect on blocking the steam. If it is too small, it may cause deformation of the juice receiving tray 50 and the steaming grid 20 under high-temperature conditions, resulting in assembly interference, and thus the phenomenon of air leakage in the whole electric steamer. Therefore, H1 cannot be too large or too small. In this embodiment, 0 < H1 ≤ 5 mm ensures that the baffle 213 has a good effect on blocking the steam, and the juice receiving tray 50 and the steaming grid 20 will not have assembly interference resulting in air leakage. In some specific embodiments, H1 can be 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 1.8 mm, 2 mm, 2.3 mm, 2.5 mm, 2.8 mm, 3 mm, 3.3 mm, 3.5 mm, 3.8 mm, 4 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5 mm, or any other value within the range of 0 < H1 ≤ 5 mm. Preferably, 2 mm ≤ H1 ≤ 4 mm.

[0051] Further, please refer to Figure 4, the distance between the part with the outward-turned edge 54 at the top of the juice-receiving side wall 52 and the lower surface of the bottom wall of the steaming grid 20 opposite thereto is H2, where 0 < H2 ≤ 5 mm. The part with the outward-turned edge 54 at the top of the juice-receiving side wall 52 blocks the steam flowing from below the bottom wall of the steaming grid 20 to the first temperature-measuring avoidance hole 212. If this distance H2 is too large, there is no obvious effect on blocking the steam. If it is too small, it may cause deformation of the juice-receiving tray 50 and the steaming grid 20 under high-temperature conditions, resulting in assembly interference and thus air leakage in the whole electric steamer. Therefore, H2 should neither be too large nor too small. In this embodiment, 0 < H2 ≤ 5 mm ensures that the part with the outward-turned edge 54 at the top of the juice-receiving side wall 52 has a good effect on blocking the steam, and there will be no assembly interference between the juice-receiving tray 50 and the steaming grid 20 leading to air leakage. In some specific embodiments, H2 can be 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 1.8 mm, 2 mm, 2.3 mm, 2.5 mm, 2.8 mm, 3 mm, 3.3 mm, 3.5 mm, 3.8 mm, 4 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5 mm, or any other value within the range of 0 < H2 ≤ 5 mm. Preferably, 2 mm ≤ H2 ≤ 4 mm.

[0052] In this embodiment, the steaming grid 20 is a disk-shaped structure, which is equivalent to the bottom part of a steamer with a bottomless steamer basket. This steaming grid 20 is used in combination with the bottomless steamer basket 80 to expand the capacity of the cooking cavity 23. As Figure 1 shown, the 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.
