Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
It should be noted that, in the case of no conflict, the technical features in the embodiments and examples of the present invention may be combined with each other, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present invention, and should not be construed as an improper limitation of the present invention.
In the description of the present application, the "top" and "bottom" orientations and positional relationships are based on the orientation and positional relationship shown in fig. 2, wherein "height" is the top-bottom direction of fig. 2, it being understood that these orientation terms are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be considered limiting of the present application.
Referring to fig. 1 and 2, the furnace 100 includes a water jacket 1 and a tray 2, wherein the water jacket 1 includes an outer shell 11, a partition wall 12 and a burner mounting portion 15. The outer case 11 has an inner cavity 1a, and a partition wall 12 is provided in the inner cavity 1a and partitions the inner cavity 1a into a waste heat recovery cavity 1b and a water storage cavity 1c, the water storage cavity 1c having a cold water inlet 1e and a hot water outlet 1 f. The furnace end mounting part 15 is arranged in the waste heat recovery cavity 1b and is close to the bottom of the waste heat recovery cavity 1b, and an opening 1d is formed in one end, far away from the furnace end mounting part 15, of the waste heat recovery cavity 1 b. Tray 2 has flue gas entry 2a, and 2 lids of tray are established in opening 1d department, and flue gas entry 2a is towards furnace end installation portion 15, and the flame that the furnace end 200 burning fuel of energy-saving stove produced can pass flue gas entry 2a, and the flue gas that furnace end 200 burning fuel produced can get into in waste heat recovery chamber 1b through flue gas entry 2 a.
Specifically, the burner mounting part 15 is used for mounting the burner 200, and the overall dimension of the flue gas inlet 2a is larger than that of the burner 200, so that not only can the flame generated by burning fuel by the mounted burner 200 pass through the flue gas inlet 2a, but also the flue gas generated by burning fuel by the burner 200 can enter the waste heat recovery chamber 1b through the flue gas inlet 2 a. When the energy-saving stove is used, kitchen utensils such as a wok are erected on the tray 2, and the heat generated by burning fuel by the furnace end 200 is utilized to heat the kitchen utensils. Because the kitchen utensils and appliances such as wok erected on the tray 2 can block the smoke from outwards diffusing to a certain extent, a large amount of smoke can enter the waste heat recovery cavity 1b through the smoke inlet 2 a. Meanwhile, the tray 2 covered at the opening 1d of the water jacket 1 can further prevent the smoke entering the waste heat recovery cavity 1b from being emitted outwards again, that is, the existence of the tray 2 enables a relatively closed space to be formed in the waste heat recovery cavity 1b, and therefore the waste heat generated by the smoke in the waste heat recovery cavity 1b can be fully utilized to heat the water stored in the water storage cavity 1 c. Generally, the temperature of the flue gas generated by the energy-saving stove in the using process is above 600 ℃, therefore, by adopting the hearth 100 of the embodiment, the cold water entering the water storage cavity 1c from the cold water inlet 1e can be rapidly heated, the single-opening stove can produce about 70 ℃ hot water per hour, and the waste heat recovery efficiency reaches above 20%, so that the utilization rate of the waste heat can be greatly improved, and the cost of a large amount of hot water for a kitchen can be saved.
The water jacket 1 of the present embodiment may be manufactured by welding or may be integrally formed, however, the welding method is adopted for many welding seams, the quality is not easy to be ensured, and particularly, the welding seams may be cracked in the process of repeatedly heating the water jacket 1, and therefore, it is preferable to manufacture the water jacket 1 by an integrally formed processing method, for example, by opening a mold.
Referring to fig. 2, the water storage cavity 1c partitioned by the partition wall 12 of the present embodiment is located at the periphery and the bottom of the waste heat recovery cavity 1b, so that the capacity of the waste heat recovery cavity 1b can be greatly increased to store more water, and the water in the water storage cavity 1c can be sufficiently heated, thereby increasing the heating speed of the water. It is understood that, in another embodiment, the water storage cavity 1c may be only disposed at the periphery of the waste heat recovery cavity 1b, or the water storage cavity 1c may be only disposed at one side of the waste heat recovery cavity 1b, as long as it is ensured that the waste heat energy in the waste heat recovery cavity 1b heats the water in the water storage cavity 1 c.
Referring to fig. 2, the burner mounting portion 15 is a burner fixing frame.
Specifically, in order to ensure that the heat generated by burning fuel at the furnace end 200 can sufficiently heat the kitchen ware, it is required to ensure that the setting height of the furnace end 200 can meet the use requirement of the energy-saving stove. Generally, the burner 200 may be directly fixed on the bottom wall of the furnace 100, however, the height of the burner 200 itself is not high, and if the burner 200 is directly fixed on the bottom wall of the furnace 100, the height of the water jacket 1 also needs to be reduced accordingly, thereby resulting in a relatively small capacity of the water storage chamber 1 c. Therefore, in order to increase the capacity of the water storage cavity 1c as much as possible, in the present embodiment, the burner mounting portion 15 is designed to be a fixed frame with a certain height, and the fixed frame is disposed in the waste heat recovery cavity 1b, so that the installation height of the burner 200 can be ensured to meet the use requirement of the energy saving stove, the height of the water jacket 1 can be increased, and the capacity of the water storage cavity 1c can be increased.
With reference to fig. 2, a flue gas outlet 1g communicated with the waste heat recovery chamber 1b is formed on the water jacket 1 of the present embodiment; the flue gas outlet 1g is close to the cold water inlet 1 e.
Specifically, the flue gas outlet 1g of this embodiment is arranged at the bottom of the water jacket 1, and the tail gas pipe 16 is communicated with the flue gas outlet 1g, so that the flue gas can discharge excessive flue gas in the waste heat recovery cavity 1 b. In addition, in the process of heating cold water entering the water storage cavity 1c, a large amount of residual heat in the flue gas is absorbed, so that the temperature of the discharged flue gas can be reduced to below 150 ℃, the temperature around a cook can be obviously reduced by 3-5 ℃ in the cooking process, and the working environment of the cook can be greatly improved. Further, since the temperature of water in the vicinity of the cold water inlet 1e is lower than that of water at other positions, the temperature of the flue gas discharged from the tail gas pipe 16 can be lowered more quickly by disposing the flue gas outlet 1g near the cold water inlet 1 e.
Referring to fig. 2, the hot water outlet 1f of the present embodiment is disposed on the bottom wall of the water storage cavity 1c, the water jacket 1 further includes a hot water outlet pipe 14 disposed in the water storage cavity 1c, one end of the hot water outlet pipe 14 passes through the hot water outlet 1f, and the other end of the hot water outlet pipe 14 is close to the top wall of the water storage cavity 1 c.
Specifically, the hot water outlet pipe 14 mainly functions to lead hot water obtained after heating out of the water storage cavity 1c, and the end of the hot water outlet pipe 14 away from the hot water outlet 1f is disposed at a position close to the top wall of the water storage cavity 1c, so that when the water level in the water storage cavity 1c is lower than the end face of the end of the hot water outlet pipe 14 away from the hot water outlet 1f, water in the water storage cavity 1c cannot flow out of the hot water outlet 1f, that is, a certain amount of water is always stored in the water storage cavity 1c, and therefore, the water jacket 1 can be prevented from being damaged due to dry burning of residual heat in flue gas after the water in the water storage cavity 1c is emptied. In another embodiment, the hot water outlet 14 may not be provided, for example, the hot water outlet 1f may be provided on a sidewall of the water storage chamber 1c at a certain height from the bottom of the water storage chamber 1c, thereby performing a dry heating prevention function.
Referring to fig. 1, since the hot water outlet 1f of the present embodiment cannot empty the water in the water storage cavity 1c, a drain outlet 1h is further disposed on the bottom wall of the water storage cavity 1c of the present embodiment, so that when the water is needed, for example, when the energy saving stove is not used for a long time, the water stored in the water storage cavity 1c can be drained through the drain outlet 1 h.
Referring to fig. 1 and fig. 2, the furnace 100 of the present embodiment further includes a heat storage member 3, and the heat storage member 3 is sleeved in the tray 2, so that the flame generated by the burner 200 combusting the fuel can be located in the space surrounded by the heat storage member 3.
Specifically, the heat storage part 3 can store heat during the process of burning the fuel at the burner 200 to avoid heat loss. The heat storage member 3 may be a reflective sheet or a metal heat storage net. However, the reflective sheet is generally made of cast iron, and the heat storage effect is poor, and the metal heat storage net can keep the interior of the furnace 100 in a red hot state all the time, and the heat storage effect is good, so the metal heat storage net is preferably used, and more preferably, a honeycomb-type metal heat storage net can be used.
In another aspect of the present application, referring to fig. 2 and 3, an energy saving stove is provided, and includes a furnace end 200 and the furnace chamber 100, where the furnace end 200 is disposed on the furnace end mounting portion 15.
The noise of the ordinary kitchen range is very high when the kitchen range works, although the national standard is below 80 decibels, the noise of most kitchen ranges on the market far exceeds the standard. When the cook exchanges in the kitchen, need pull the throat and shout, consequently, the furnace end 200 of this embodiment can adopt the silence furnace end, uses the low noise fan (not shown) cooperation of silence furnace end and energy-conserving kitchen, can control the noise about 65 decibels to can make the noise greatly reduced in kitchen, and then can not influence the interchange between the cook.
Further, the energy-saving stove of the present embodiment further includes a temperature control device (not shown), and the temperature control device includes a temperature probe, a control element, and an electromagnetic switch valve. The temperature probe is arranged at the hot water outlet 1f, the control element is electrically connected with the temperature probe, and the electromagnetic switch valve is arranged at the cold water inlet 1e and is electrically connected with the control element.
Specifically, the temperature probe is mainly used for detecting the water temperature at the hot water outlet 1f and transmitting the detected water temperature to the control element in the form of a temperature signal, and the control element is used for controlling the opening and closing of the electromagnetic switch valve according to the set water temperature. For example, the set water temperature of the control element may be set to 60 ℃, and when the temperature signal received by the control element indicates that the current water temperature at the hot water outlet 1f is lower than 60 ℃, the control element controls the electromagnetic switch valve to close the cold water inlet 1e, so as to prevent cold water from entering the water storage cavity 1 c; when the temperature signal received by the control element indicates that the temperature of the water at the current hot water outlet 1f is higher than 60 ℃, the control element controls the electromagnetic switch valve to open the cold water inlet 1e, so that the cold water can enter the water storage cavity 1 c. It can be understood that the set water temperature is not limited to 60 ℃, and the specific set water temperature can be adjusted as required to meet different use requirements.
The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
