Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more specifically, to an exhaust device and an integrated stove. Background Technology

[0002] An integrated cooktop is a kitchen appliance that combines a cooktop with other cooking equipment (such as a steamer, oven, or steam-grill combination appliance). The cooking equipment is usually located below the cooktop.

[0003] In related technologies, integrated cooktops generally use the existing range hood in the kitchen to deal with the oil fumes generated when the integrated cooktop is working. However, since the cooking equipment is located below the cooktop, the water vapor generated by the cooking equipment is difficult to be discharged outside the integrated cooktop, resulting in poor water vapor treatment effect of the integrated cooktop.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] Please see Figures 1-3 This application provides an integrated stove 1, which is a kitchen appliance that combines a stove and a cooking device (not shown in the figure). The cooking device can be a steam oven, an oven, or a steam oven, etc. This application does not specifically limit the type of cooking device.

[0037] The integrated cooktop 1 may include a cooktop shell 10 and an exhaust system 20. The cooktop shell 10 includes a cooktop housing 11 and a cooktop panel 12. The cooktop housing 11 has a receiving cavity 11a, in which part of the exhaust system 20 is installed, and the cooktop panel 12 is used to cover the receiving cavity 11a. That is, the cooktop panel 12 covers the opening of the receiving cavity 11a to prevent the exhaust system 20 from being exposed to the air, thereby protecting the exhaust system 20.

[0038] Furthermore, the cooktop panel 12 is provided with an installation port 12a, which communicates with the receiving cavity 11a. It is understood that the exhaust device 20 is installed within the receiving cavity 11a, and the exhaust gas from the exhaust device 20 flows out of the integrated cooktop 1 through the installation port 12a. The exhaust gas can be understood as at least one of air, flue gas, and water vapor. It should be noted that the installation port 12a can be located on the rear side of the cooktop panel 12 to prevent the exhaust gas flowing out of the exhaust device 20 from affecting the user.

[0039] The exhaust device 20 will be described in detail below.

[0040] Please see Figures 4-6 The exhaust device 20 includes a water box support 21, a fan assembly 22, a connector assembly 23, and a water receiving box 24. At least a portion of the water box support 21, the fan assembly 22, the connector assembly 23, and the water receiving box 24 are all installed within the receiving cavity 11a.

[0041] Please see Figures 5-6Specifically, the water box support 21 includes an air duct shell 211 and a steam duct shell 212 surrounding the air duct shell 211. The air duct shell 211 has an air duct 211a, and a steam duct 212a is formed between the air duct shell 211 and the steam duct shell 212. The fan assembly 22 is connected to and communicates with the air duct shell 211. The fan assembly 22 is a device that converts mechanical energy into airflow energy, and is used to achieve ventilation. It has functions such as heat dissipation and air supply; the connector assembly 23 is connected and communicates with the steam duct shell 212; the water receiving box 24 is partially installed in the water box support 21, and the water receiving box 24 can be used to receive the condensate water that flows back from the condensation of steam; the water receiving box 24 has an exhaust port 24a, which is connected to both the air duct 211a and the steam duct 212a, so that the air in the air duct 211a and the steam in the steam duct 212a are mixed at the exhaust port 24a.

[0042] Understandably, when the fan assembly 22 is working, air is drawn into the fan assembly 22 and blown into the air duct 211a by the rotation of the fan assembly 22; one end of the connector assembly 23 is connected to the steam duct shell 212, and the other end of the connector assembly 23 is connected to the steam exhaust pipe (not shown in the figure) of the cooking equipment. When the cooking equipment is working, the steam generated by the cooking equipment can flow into the steam duct 212a through the steam exhaust pipe and the connector assembly 23; and since the exhaust port 24a is connected to both the air duct 211a and the steam duct 212a, as the air in the air duct 211a and the steam in the rectifier duct flow, the air in the air duct 211a and the steam in the rectifier duct mix at the exhaust port 24a, and the steam drives the air to be discharged to the outside of the integrated stove 1 by natural ejection. Furthermore, driven by the fan assembly 22, air can quickly mix with steam at the exhaust port 24a, and the air has a certain flow rate at this time, which can accelerate the speed at which steam and air are discharged after mixing, thereby increasing the speed at which steam is discharged from the integrated stove 1. At the same time, because the speed at which steam is discharged from the integrated stove 1 is accelerated, the amount of steam condensing into condensate in the steam duct 212a is reduced. This prevents excessive condensate in the steam duct 212a from flowing back into the cooking equipment through the steam duct 212a, the connector assembly 23, and the steam exhaust pipe.

[0043] Furthermore, when the cooking equipment is in operation, the temperature of the fumes and steam produced exceeds 100 degrees Celsius. If the steam is directly discharged from the exhaust port 24a, the high temperature of the fumes and steam could easily burn the user. Therefore, by installing a fan assembly 22 inside the exhaust device 20, and ensuring that the fan assembly 22 operates whenever the cooking equipment is in operation, the steam temperature decreases after mixing with air at the exhaust port 24a. In other words, the steam temperature is reduced before it is discharged from the exhaust port 24a to the outside of the integrated stove 1, thus preventing the user from being burned by the steam.

[0044] It should be noted that the embodiments of this application do not specifically limit the type of fan assembly 22. For example, the fan assembly 22 can be a cross-flow fan or an axial flow fan.

[0045] In this embodiment, an air duct shell 211 and a steam duct shell 212 surrounding the air duct shell 211 are provided on the water box support 21. The air duct shell 211 has an air duct 211a, and a steam duct 212a is formed between the air duct shell 211 and the steam duct shell 212. The water box 24 has an exhaust port 24a, which is connected to the air duct 211a and the steam duct 212a. Driven by the fan assembly 22, the air in the air duct 211a and the steam in the steam duct 212a mix at the exhaust port 24a. At the same time, the steam can carry the air out of the integrated stove 1 from the exhaust port 24a. In this way, on the one hand, the speed of steam discharge from the integrated stove 1 can be increased, and on the other hand, the steam temperature can be reduced to prevent the user from being scalded by the steam.

[0046] Please see Figure 7 In some embodiments, the air duct housing 211 includes an air inlet housing 2111 and an air outlet housing 2112.

[0047] Specifically, the inlet shell 2111 is connected and communicates with the fan assembly 22; the outlet shell 2112 is smoothly connected and communicates with the inlet shell 2111. It can be understood that when the fan assembly 22 is working, it creates a negative pressure, and air enters the inlet shell 2111 through the vent, then flows through the fan assembly 22 into the outlet shell 2112. The inlet shell 2111 contains an inlet section 2111a, and the outlet shell 2112 contains an outlet section 2112a. The inlet section 2111a and the outlet section 2112a communicate to form an air duct 211a. That is, air enters from the inlet section 2111a and flows out from the outlet section 2112a, and the outlet section 2112a communicates with the exhaust port 24a, allowing air and steam to mix at the exhaust port 24a.

[0048] Please continue reading. Figure 7Furthermore, in some embodiments, the central axis of the air inlet shell 2111 is set at an angle to the central axis of the air outlet shell 2112. That is, by setting the air inlet shell 2111 and the air outlet shell 2112 at an angle, the direction of airflow is changed, thereby enabling air to flow to the exhaust port 24a. In addition, compared with the linear airflow direction in related technologies, the present embodiment, by setting the central axis of the air inlet shell 2111 and the central axis of the air outlet shell 2112 at an angle, can make the airflow direction angled, thereby shortening the airflow path.

[0049] Please see Figures 7-8 In some embodiments, the water box support 21 further includes a front side plate 213, a rear side plate 214, a first partition 215, and a second partition 216.

[0050] Specifically, the rear side plate 214 and the front side plate 213 are arranged opposite each other in the front-rear direction AA of the exhaust device 20; the first partition 215 is connected to both the front side plate 213 and the rear side plate 214; the second partition 216 is connected to both the front side plate 213 and the rear side plate 214, and the second partition 216 and the first partition 215 are arranged opposite each other in the left-right direction BB of the exhaust device 20. The front side plate 213, the rear side plate 214, the first partition 215, the second partition 216, and the air duct shell 211 together constitute the steam duct shell 212. It can be understood that the steam generated during the operation of the cooking equipment flows to the connector assembly 23, and since the connector assembly 23 is connected and communicates with the steam duct shell 212, the steam flows through the connector assembly 23 into the steam duct 212a, so that the steam in the steam duct 212a mixes with the air in the air duct 211a at the exhaust port 24a.

[0051] Please continue reading. Figures 7-8 In some embodiments, the air duct housing 211 passes through the front side panel 213 and is connected to the front side panel 213, so that the air duct housing 211 is connected and communicates with the fan assembly 22. That is, since the air duct housing 211 passes through the front side panel 213, the air duct housing 211 extends to the side of the front side panel 213 near the fan assembly 22, thus facilitating the connection between the air duct housing 211 and the fan assembly 22.

[0052] Furthermore, the air duct shell 211 is spaced apart from the first partition 215, the second partition 216, and the rear side plate 214 to form a steam duct 212a. It can be understood that the steam ring of the steam duct 212a is located in the gaps formed between the air duct shell 211 and the first partition 215, the second partition 216, and the rear side plate 214 to increase the steam flow area and thus improve the steam discharge speed.

[0053] Please see Figure 7 In some embodiments, the fan assembly 22 includes a fan body 222, a fan bracket 221, and a fan cover 223.

[0054] Specifically, the fan body 222 is connected to the air duct shell 211 and communicates with the air duct 211a. The fan body 222 typically consists of a motor and an impeller. The working principle of the fan body 222 is mainly that the motor drives the impeller to rotate at high speed, compressing and accelerating the air, thereby giving the air power and generating airflow. That is, under the action of the fan body 222, the air flows into the air duct shell 211.

[0055] The fan bracket 221 is connected to the front side plate 213 and the fan body 222. That is, the fan bracket 221 is connected to the fan body 222 so that the fan body 222 is fixed on the fan bracket 221. The fan bracket 221 is connected to the front side plate 213 so that it is fixed on the front side plate 213, thereby fixing the fan assembly 22 on the front side plate 213.

[0056] The fan cover 223 is connected to the fan body 222, and the fan cover 223 and the fan bracket 221 are positioned opposite each other in the vertical direction CC of the exhaust device 20. It is understood that the fan assembly 22 needs to draw in outside air when it is operating; however, the fan assembly 22 may also draw in other impurities into the fan body 222, potentially damaging the impeller. Therefore, the fan cover 223 protects the impeller from damage by these impurities. Simultaneously, the fan cover 223 effectively guides airflow to ensure the smooth operation of the fan body 222.

[0057] Please continue reading. Figure 7 Specifically, in some embodiments, the front side plate 213 is provided with a first through hole 213a, and the fan bracket 221 is provided with a second through hole 221a; the exhaust device 20 also includes a first screw connector (not shown in the figure), which passes through the first through hole 213a and the second through hole 221a to fix the fan bracket 221 to the front side plate 213. That is, by the first screw connector passing through the first through hole 213a and the second through hole 221a, the fan bracket 221 is fixedly connected to the front side plate 213, thereby improving the stability of the fan bracket 221 installed on the front side plate 213.

[0058] Please continue reading. Figure 7In other embodiments, the fan body 222 is provided with a third through hole 222a; the fan bracket 221 is provided with a fourth through hole 221b; the exhaust device 20 further includes a second screw connector (not shown in the figure), which passes through the third through hole 222a and the fourth through hole 221b to install the fan bracket 221 onto the fan body 222. It is understood that by having the second screw connector pass through the third through hole 222a and the fourth through hole 221b, a fixed connection between the fan bracket 221 and the fan body 222 is achieved, thereby improving the stability of the fan bracket 221 installed on the fan body 222.

[0059] Please continue reading. Figure 7 In some embodiments, the front side plate 213 is provided with a first through hole 213a; the fan bracket 221 is provided with a second through hole 221a and a fourth through hole 221b; the fan body 222 is provided with a third through hole 222a; the exhaust device 20 includes a first screw connector and a second screw connector, wherein the first screw connector passes through the first through hole 213a and the second through hole 221a, and the second screw connector passes through the third through hole 222a and the fourth through hole 221b. That is, the fan body 222 is fixedly connected to the front side plate 213 through the fan bracket 221, thereby realizing the connection between the fan assembly 22 and the front side plate 213, and thus improving the stability of the fan assembly 22 installed on the front side plate 213.

[0060] Please see Figure 7 as well as Figure 9 Furthermore, the cooktop housing 11 includes a bottom shell 111, which has a fifth through hole 111a; the front side panel 213 also has a sixth through hole 213b; the integrated cooktop 1 also includes a third screw connector (not shown in the figure), which passes through the fifth through hole 111a and the sixth through hole 213b to install the water box support 21 onto the bottom shell 111. That is, the third screw connector can fix the water box support 21 onto the bottom shell 111, thereby improving the stability of the installation between the water box support 21 and the bottom shell 111.

[0061] Please see Figures 7-8 In some embodiments, the water box support 21 further includes a left side plate 217 and a right side plate 218.

[0062] Specifically, the left side plate 217 is connected to the front side plate 213 and the rear side plate 214. The left side plate 217 and the first partition plate 215 are arranged opposite each other in the left-right direction BB of the exhaust device 20. The left side plate 217, the front side plate 213, the first partition plate 215 and the rear side plate 214 together form the first mounting groove 21a. The right side plate 218 is connected to the front side plate 213 and the rear side plate 214. The right side plate 218 and the second partition plate 216 are arranged opposite each other in the left-right direction BB of the exhaust device 20. The left side plate 217, the front side plate 213, the second partition plate 216 and the rear side plate 214 together form the second mounting groove 21b. The right side plate 218 and the left side plate 217 are located on opposite sides of the whole formed by the first partition plate 215 and the second partition plate 216, respectively. That is, the first mounting groove 21a and the second mounting groove 21b are spaced apart on the left and right sides of the exhaust device 20, and the steam duct shell 212 is between the first mounting groove 21a and the second mounting groove 21b. At least part of the water receiving box 24 is installed in the first mounting groove 21a and the second mounting groove 21b, so that the water receiving box 24 is at least partially installed in the water box support member 21, thereby reducing the overall size of the exhaust device 20.

[0063] It should be noted that the water tank support 21 and the water collection box 24 are detachably connected. Understandably, during the venting process, the steam generated by the cooking equipment condenses to form condensate, which flows into the water collection box 24. In other words, the water collection box 24 can be used to collect the condensate generated inside the cooking equipment, preventing excessive condensate from flowing back into the internal space of the cooking equipment. Furthermore, since the water tank support 21 and the water collection box 24 are detachably connected, when the water collection box 24 collects a large amount of condensate, the user can disassemble the water collection box 24 and empty the condensate for convenient condensate disposal.

[0064] Please see Figure 8 Furthermore, in some embodiments, the water receiving box 24 includes a first water holding box 241, a partition 242, and a second water holding box 243. The partition 242 is connected to the first water holding box 241 and has a vent 24a. The second water holding box 243 is connected to the partition 242 and the second water holding box 243 is connected to the partition 242. The second water holding box 243 and the first water holding box 241 are spaced apart in the left-right direction BB of the venting device 20. That is, the first water holding box 241 is installed in the first mounting groove 21a, and the second water holding box 243 is installed in the second mounting groove 21b, so that at least a portion of the water receiving box 24 is installed on the water box support 21, thereby reducing the overall size of the venting device 20.

[0065] Please continue reading. Figure 8In some embodiments, the separator 242 includes a first separator sub-component 2421 and a second separator sub-component 2422.

[0066] Specifically, the first partition sub-component 2421 is connected to the first water container 241, and the first partition sub-component 2421 has a first opening 2423 facing the first partition 215; the second partition sub-component 2422 is connected to the second water container, and the second partition sub-component 2422 and the first partition sub-component 2421 are arranged opposite each other in the left-right direction BB of the exhaust device 20, and the second partition sub-component 2422 has a second opening 2424 facing the second partition 216. It can be understood that in order to better install the first water container 241... The water receiving box 24 is installed into the first mounting slot 21a, and the second water holding box 243 is better installed into the second mounting slot 21b. Therefore, the first partition sub-piece 2421 is provided with a first opening 2423 facing the first partition plate 215, and the second partition sub-piece 2422 is provided with a second opening 2424 facing the second partition plate 216. The top end of the first partition plate 215 extends into the first opening 2423, and the top end of the second partition plate 216 extends into the second opening 2424. In this way, the water receiving box 24 can be installed in the water box support member 21.

[0067] In some embodiments, the exhaust device 20 further includes a seal, which is an accessory used for sealing. Seals are mostly made of rubber and possess characteristics such as corrosion resistance, tear resistance, and elasticity.

[0068] Please see Figures 8-9Furthermore, the water box support 21 also includes a base plate 219, which is connected to the front side plate 213, the rear side plate 214, the first partition 215, and the second partition 216. The base plate 219 includes a frame 2191, which is connected to and communicates with the steam duct shell 212 and the connector assembly 23. The frame 2191 extends from the base plate 219 toward the connector assembly 23 and is provided with a sealing mounting groove 2192, in which a seal is installed. Understandably, when the cooking equipment is working, steam flows from the connector assembly 23 through the frame 2191 into the steam duct housing 212, mixes with the air in the air duct 211a at the exhaust port 24a, and is then discharged outside the integrated stove 1. However, steam easily forms condensation when it encounters cold external air. Most of the condensation can be collected by the water collection box 24, but a small portion of the condensation will flow back from the steam duct 212a to the connector assembly 23. During the condensation backflow process, since the connector assembly 23 is connected to the frame 2191, and there may be a gap between the connector assembly 23 and the frame 2191, the condensation may seep into the internal space of the cooking equipment, affecting other components of the cooking equipment and making it difficult for the user to clean the condensation inside the cooking equipment. Therefore, by installing a seal in the sealing mounting groove 2192 to seal the gap between the connector assembly 23 and the frame 2191, the seepage of condensation into the internal space of the cooking equipment is prevented, thus improving the sealing performance between the connector assembly 23 and the frame 2191.

[0069] Please see Figure 9 Furthermore, in some embodiments, the enclosure 2191 includes a first sub-enclosure 2193 and a second sub-enclosure 2194. The first sub-enclosure 2193 is connected to and communicates with the steam duct shell 212; the second sub-enclosure 2194 is connected to and communicates with the connector assembly 23, and the second sub-enclosure 2194 is interference-fitted with the first sub-enclosure 2193 to form a sealing mounting groove 2192. That is, a portion of the second sub-frame 2194 extends into the first sub-frame 2193, so that the second sub-frame 2194 and the first sub-frame 2193 are interference-fitted, while another portion of the second sub-frame 2194 extends toward the connector assembly 23, and the size of the second sub-frame 2194 is smaller than the size of the first sub-frame 2193, so that the other portion of the second sub-frame 2194 forms a sealing mounting groove 2192; when the second sub-frame 2194 is connected and communicates with the connector assembly 23, the seal can be installed in the sealing mounting groove 2192, and then the connection between the second sub-frame 2194 and the connector assembly 23 is realized, thus improving the sealing performance between the second sub-frame 2194 and the connector assembly 23.

[0070] It should be noted that the second sub-frame 2194 and the first sub-frame 2193 can be an integral component to reduce the installation steps of the exhaust device 20, thereby improving the ease of installation of the exhaust device 20.

[0071] Please see Figures 8-9 In some embodiments, the connector assembly 23 includes a connector tube 231, a connecting tube 232, and a connector 233.

[0072] Specifically, connector pipe 231 is connected to and communicates with the steam exhaust pipe (not shown in the figure) of the cooking equipment; connecting pipe 232 is connected to and communicates with connector pipe 231; connector 233 is connected to and communicates with connecting pipe 232 and frame 2191. That is, the seal is sandwiched between the outer peripheral wall of frame 2191 and the inner peripheral wall of connector 233, so that the seal is installed in sealing mounting groove 2192, thereby improving the sealing performance between connector assembly 23 and frame 2191.

[0073] It should be noted that the connector pipe 231, connecting pipe 232, and connector 233 can be an integral component. This improves the ease of installation of the connector assembly 23 and prevents condensate from seeping into the internal space of the cooking equipment. Of course, the connector pipe 231, connecting pipe 232, and connector 233 can also be separate components; this embodiment does not specifically limit this.

[0074] Please see Figure 9 Since the connector assembly 23 is detachably connected to the frame 2191, to prevent the connector assembly 23 from becoming loose during installation, the stove bottom shell 111 is provided with a seventh through hole 111b, and the connector 233 has an eighth through hole 233a. The integrated stove 1 also includes a fourth screw connector (not shown in the figure), which passes through the seventh through hole 111b and the eighth through hole 233a to fix the connector assembly 23 to the stove bottom shell 111. That is, by using the fourth screw connector to pass through the seventh through hole 111b and the eighth through hole 233a, a fixed connection between the connector assembly 23 and the stove bottom shell 111 is achieved, thereby improving the stability of the connector assembly 23 installed on the stove bottom shell 111.

[0075] Please continue reading. Figure 9 Furthermore, in some embodiments, the central axis of the connector pipe 231 is set at an angle to the central axis of the connecting pipe 232. That is, when the steam exhaust pipe of the cooking equipment is connected to the connector pipe 231, since the connector pipe 231 and the connecting pipe 232 are set at an angle, and the connector pipe 231 extends along the left-right direction BB of the exhaust device 20, the steam exhaust pipe of the cooking equipment can extend from the rear of the integrated stove 1 to connect with the connector pipe 231. In this way, it is convenient to install the steam exhaust pipe of the cooking equipment onto the connector pipe 231.

[0076] Please see Figure 2 as well as Figure 8 In some embodiments, the exhaust device 20 further includes a vent cover 26, which covers the exhaust port 24a to prevent external debris from entering the interior of the exhaust device 20 through the exhaust port 24a. The vent cover 26 has a vent 26 that communicates with the exhaust port 24a. That is, the air from the air duct 211a and the steam from the steam duct 212a, after mixing at the exhaust port 24a, can be discharged outside the integrated stove 1 through the vent 26 to achieve steam discharge. At the same time, providing a vent 26 on the vent cover 26 can reduce the pressure loss after the air and steam mix and flow out, thereby increasing the steam discharge volume.

[0077] Furthermore, in some embodiments, in the vertical direction CC of the exhaust device 20, the distance between the inner wall of the vent cover 26 and the top wall of the exhaust port 24a is greater than or equal to 5 mm. It is understood that...

[0078] When the fan assembly 22 draws in air, a negative pressure is generated at the air inlet of the fan assembly 22. If the distance between the top wall of the exhaust port 24a and the inner wall of the vent cover 26 is too short, the air at the exhaust port 24a can easily generate greater pressure, thus affecting the working efficiency of the fan assembly 22. Therefore, by setting the distance between the inner wall of the vent cover 26 and the top wall of the exhaust port 24a to be greater than or equal to 5mm, the distance between the vent cover 26 and the top wall of the exhaust port 24a is increased, thereby reducing the pressure loss after the air and steam mix and flow out, and thus improving the working efficiency of the fan assembly 22.

[0079] Please continue reading. Figure 2 as well as Figure 8 In some embodiments, the integrated stove 1 further includes a decorative panel 30, which is connected to and protrudes from the stove panel 12. The decorative panel 30 protrudes from the stove panel 12 to prevent condensate from overflowing from the stove panel 12 during the steam discharge process of the exhaust device 20. The decorative panel 30 is used to cover the installation opening 12a to prevent external debris from entering the interior of the exhaust device 20 from the installation opening 12a.

[0080] Furthermore, the decorative panel 30 has a third opening 30a, and a vent cover 26 is installed on the decorative panel 30, with the third opening 30a communicating with the exhaust port 24a. It is understood that the vent cover 26 is used to cover the third opening 30a and the exhaust port 24a, and the vent 26 on the vent cover 26 is communicating with both the third opening 30a and the exhaust port 24a, so that air and steam mix at the exhaust port 24a and then flow from the third opening 30a and the vent 26 to the outside of the integrated stove 1.
