Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of integrated stoves, and in particular to a casing assembly of an integrated stove and an integrated stove having the casing assembly of the integrated stove. Background Art
[0002] Integrated stoves are popular with users for their reasonable use of the space under the kitchen stove, integration with the kitchen, the smoke is sucked away by the negative pressure formed by the fan before it spreads, and the noise source is placed below. The ability to absorb and exhaust smoke is the core ability of integrated stoves. By increasing the air volume and pressure of the internal fan, the smoke extraction effect can be improved to a certain extent. However, while improving the smoke extraction effect, high air volume and high air pressure will increase the noise of the whole machine to a certain extent.
[0003] Integrated stoves in related technologies usually include a head, a body, a fume removal fan system, a stove assembly, and additional assemblies (such as a disinfection cabinet, a steam oven, or a dishwasher, etc.). The fan is placed inside the body, and the air duct occupies a large space. The volume of the body used to accommodate additional assemblies is limited, and it is impossible to embed a dishwasher that requires a larger volume or a steam oven that requires a high depth. At the same time, the high air volume and high air pressure bring high noise, and the fan is placed in the body, which is prone to low-frequency rumbling sounds, causing users to feel irritated.
[0004] For this reason, some methods have emerged to set two motors on the left and right sides of the machine head. However, due to the interference between the two independent fan systems in the air duct, the air duct resistance is large, the air volume loss is large, and the air volume and air pressure are low. At the same time, due to the large wind resistance, the speed is high and the noise is high. The solution of more accurately controlling the flow of each fan separately still has losses when the dual fans are turned on, and it is necessary to add feedback and control modules, etc., which brings expensive control costs. At the same time, considering the narrow and long air duct of the integrated stove, this method cannot be applied to the integrated stove. Summary of the invention

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0033] The following describes a housing assembly 10 of an integrated stove according to a first embodiment of the present invention with reference to the accompanying drawings.
[0034] like Figure 1-Figure 4 As shown, the housing assembly 10 of the integrated stove according to an embodiment of the present invention includes: a body 100 , a head 200 , a negative pressure device, a first air duct 410 and a second air duct 420 .
[0035] Specifically, the body 100 is provided with a receiving cavity and an air outlet 101, and the top of the body 100 is provided with a stove 102. The head 200 is provided above the body 100, and the head 200 is located behind the stove 102. The head 200 is provided with a fan installation cavity, a first air inlet 201 and a second air inlet 202. The negative pressure device is provided in the fan installation cavity, and the negative pressure device includes a first fan 310 and a second fan 320. The inlet of the first fan 310 is connected to the first air inlet 201, and the inlet of the second fan 320 is connected to the second air inlet 202. The first air duct 410 and the second air duct 420 are independently provided, and the first air duct 410 is respectively connected to the outlet of the first fan 310 and the air outlet 101, and the second air duct 420 is respectively connected to the outlet of the second fan 320 and the air outlet 101. Here, the term "independent arrangement" means that the air flow channels of the first air duct 410 and the second air duct 420 are separated, and does not specifically mean that the first air duct 410 and the second air duct 420 are independently manufactured, that is, the first air duct 410 and the second air duct 420 can share an air duct wall, for example, the first air duct 410 and the second air duct 420 are defined in the air cylinder by the partition 11. It is understood that the partition 11 and the air cylinder can be integrally formed.
[0036] Among them, at least one of the first air duct 410 and the second air duct 420 includes an outlet extension section 401, an outlet bending section 402 and a guide section 403 connected in sequence along the direction from the outlet of the negative pressure device to the air outlet 101, and the outlet of the negative pressure device is the outlet of the first air duct 410 and / or the outlet of the second air duct 420. That is, the first air duct 410 or the second air duct 420 includes an outlet extension section 401, an outlet bending section 402 and a guide section 403, or the first air duct 410 and the second air duct 420 include an outlet extension section 401, an outlet bending section 402 and a guide section 403 respectively. The outlet extension section 401 extends in the up-down direction, and the outlet bending section 402 extends obliquely in the direction from the outlet extension section 401 to the guide section 403 (i.e., from top to bottom), so as to smoothly introduce the airflow at the outlet of the outlet extension section 401 into the guide section 403 to reduce airflow loss.
[0037] Therefore, according to the casing assembly 10 of the integrated stove according to the embodiment of the present invention, the first air duct 410 and the second air duct 420 are separated, so that the air duct resistance when the first fan 310 and the second fan 320 are turned on can be reduced, the air volume loss is small, the air volume and pressure are large, and the fan speed can be reduced, thereby the flow utilization rate is high and the noise is low; at the same time, the outlet extension section 401 is used, so that the uneven airflow coming out of the outlet of the negative pressure device will not turn directly, but will diffuse and expand, thereby reducing the impact and turbulent noise.
[0038] According to some embodiments of the present invention, the length of the outlet extension section 401 in the vertical direction is 30 mm-50 mm, thereby further reducing impact and turbulence noise. For example, the length of the outlet extension section 401 in the vertical direction is 50 mm.
[0039] According to some embodiments of the present invention, Figure 3 As shown, the outlet bending section 402 extends obliquely backward in the direction from the outlet extension section 401 to the guide section 403 (ie, from top to bottom) to leave a certain space for the stove.
[0040] Since the outlet thickness of the negative pressure device is relatively large, in order to reduce the thickness of the back of the whole machine (i.e., the head 200) (i.e., the thickness in the front-to-back direction), in some embodiments of the present invention, Figure 3 As shown, the width of the outlet bending section 402 in the front-to-back direction decreases from top to bottom. For example, the inclination angle of the front wall of the outlet bending section 402 relative to the vertical direction is greater than the inclination angle of the rear wall of the outlet bending section 402 relative to the vertical direction, so as to reduce the thickness of the back while leaving a larger space.
[0041] In some specific embodiments of the present invention, Figure 4As shown, the width of the outlet bending section 402 in the left-right direction increases from top to bottom. In this way, the flow area of the outlet bending section 402 can be kept basically unchanged, avoiding the sudden reduction of the flow area, which may cause excessive local loss of fluid during flow, dynamic pressure loss, etc., and avoid causing eddy currents and inducing noise.
[0042] According to some embodiments of the present invention, Figure 3 As shown, the outlet extension section 401 is located above the stove 102 and the outlet bending section 402 is located behind the stove 102, so as to reduce noise before the airflow enters the guide section 403 and leave a certain space for the stove.
[0043] According to some embodiments of the present invention, Figure 2 As shown, one end of the first air duct 410 adjacent to the air outlet 101 is located above one end of the second air duct 420 adjacent to the air outlet 101, and one end of the guide section 403 of the second air duct 420 adjacent to the air outlet 101 is formed with a guide structure 404, which is configured to be an arc convex downward with the tangent direction pointing to the air outlet 101. For example, the air outlet 101 is located on the left side wall of the fuselage 100, the first fan 310 is located on the left side of the second fan 320, and the lower end of the guide section 403 of the second air duct 420 is formed with a guide structure 404, which is warped upward instead of being horizontally tangent to the bottom wall of the fuselage 100, so that the airflow can be directed upward to connect with the check valve in the air outlet 101, further weakening the airflow collision in the air duct.
[0044] In some specific embodiments of the present invention, Figure 2 As shown, the tangent line X of the lower edge of the air guide structure 404 coincides with the tangent line of the lower edge of the air outlet 101 , so as to achieve a better airflow guiding effect and ensure that all the airflow is guided to the air outlet 101 .
[0045] According to a specific embodiment of the present invention, Figure 1-Figure 4 As shown, the oil smoke is sucked in by the first fan 310 and the second fan 320 placed at the head 200, and after rotation and separation, it is discharged into the common flue through the first air duct 410 and the second air duct 420 and the air guide 500 arranged at the rear of the fuselage 100. The first air duct 410 and the second air duct 420 are thin, which can save the lower side space to a large extent and provide a larger volume for the accessory assembly. At the same time, since the negative pressure device is fixed at the top, the noise in the frequency range of 300Hz-800Hz will be significantly reduced, and the low-frequency roar of the machine will be significantly improved.
[0046] A partition 11 is set from the outlet of the negative pressure device to separate the left and right air ducts, all the way to the front end of the check valve (i.e., upstream of the check valve), and a guide structure 404 is set at the outlet of the air duct to further weaken the collision of airflow in the air duct. By using the partition 11 and the guide structure 404, and extending the airflow from the outlet of the negative pressure device for a period of time before turning, the air duct resistance when the first fan 310 and the second fan 320 are turned on at the same time can be greatly reduced, the air volume can be increased, the fan speed can be reduced, and the noise can be improved.
[0047] The integrated stove 1 according to the second embodiment of the present invention comprises: the housing assembly 10 of the integrated stove according to the first embodiment of the present invention, a stove assembly 20 and an additional assembly. The stove assembly 20 is installed on the stove top 102. The additional assembly is installed in the accommodating cavity.
[0048] The integrated stove 1 according to the embodiment of the present invention utilizes the housing assembly 10 of the integrated stove as described above, so that the flow rate utilization rate is high and the noise is low.
[0049] Since the air duct is divided anyway, it will always converge at the far end, so when one fan is turned on alone, the other fan will reverse, causing the oil smoke to flow back from the other fan; however, turning on the two fans at high speed at the same time wastes energy and is noisy. To this end, according to some embodiments of the present invention, the integrated stove 1 also includes: a control module, which is used to control the first fan 310 and the second fan 320 to be turned on at the same time and separately control the speed of the first fan 310 and the second fan 320 according to the use status of the stove assembly 20. That is, when the motor on one side is turned on at high speed, the motor on the other side will start at low speed accordingly, which will not cause the motor on the other side to reverse, so that it will not cause oil smoke to flow back, and at the same time save energy, reduce noise, and the cost is not high. For example, when the left fan is turned on at high speed, the right fan is turned on at low speed at the same time. Conversely, when the right fan is turned on at high speed, the left fan is automatically turned on at low speed for coordinated use.
[0050] Other structures and operations of the integrated stove 1 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
